[Q] Samsung Display Problem !!! - Galaxy Note 3 Q&A, Help & Troubleshooting

I bought a Note 3 on October 4th 2013.... And I was an extremely proud owner of an awesome phone... And...
And then after a few days I noticed a rectangular smudge near the back button on the glass. And also a purple flickering on certain widgets when quickly moving between home screens (check below video).
https://db.tt/k8Gg6PkK
So, I asked for a phone replacement... they said no... and finally after a small fight got the glass and display replaced...
Guess what.... the new phone I got had a permanent smudge as well, but at a different location. Moreover the display issue was still there !!!
And then after a BIGGG fight they agreed to replace the phone. They said they dint have stock and finally refunded the money.
So... I waited a month... and decided to buy the Note 3 again thinking that the previous cases were just bad luck. Got it day before yesterday.
No problem with the glass and all and everything running smoothly. But...
But... the issue shown in the video was still there. So, i decided to do a small investigation. Went around a few Samsung showrooms. And as most of you know, all phones displayed in showrooms are the Snapdragon version (N9005) and not the Exynos version (I have no idea why !!!). I transferred the same background image to those phones.. added the google now widget to the home screen... and tried to reproduce the issue on the N9005s...
Guess what... In none of the shops I could reproduce the issue.... As i was about to leave the last shop, the owner walks in and he has a Note 3.... this was an Exynos version ofcourse... I tried to reproduce the issue on it...
And voila.... there it was... the same issue..... So.... I saw the same issue on different phones.... but all were the Exynos ones..... the Snapdragon versions have no probs !!!
So the question is..... WHAT IS GOING ON ? ARE WE BEING SOLD SUB STANDARD PRODUCTS IN INDIA ? WHY DOES BOTH THE VERSIONS HAVE DIFFERENT DISPLAYS ? OR IS IT A CHIPSET ISSUE ? OR A GPU ISSUE ? OR A DISPLAY DRIVER ISSUE ?
I AM JUST SAD !!!

Geez... u have to screw the samsung there for displaying snapdragon, but yet selling exynos.
This is a cheating to consumer.

Well, I definitely would luv to... Then I will have to put in all that time and effort. But I am seriously considering it... !!!
Anyone else seen similar issues ?
The easiest way to reproduce is when you have a new device and have not used the S-notes. Have the S-note widget on the homescreen. Just tap on it. This will open the welcome page for the S-note... its like a small video.... so between the time when the widget is touched and that video kinda thingy comes up you should be able to see the purple patches here and there....

You can get rid/minimise the purple cast by using Lux. Go under night mode and decrease the screen temp(warm up). Doing this may exacerbate other shortcomings of the screen though.
e.g lines and splotches on grey backgrounds.

Well... I had read about the purple smearing even before buying the Note 3....This should be the workaround to reduce that I suppose ?
Smearing is OK.... this is like random purple patches coming up here and there.... And what concerns me is why it is seen only on the Exynos version and not on the Snapdragon one !!!
Any explanation for that ?

I looked at the vid you uploaded and saw you trying to replicate the purple smearing(quickly transioning between homescreens). I didn't see any purple splotches(not saying they don't exist).
I myself own a Snapdragon N3 and the smearing is present, aswell as a line that runs across the screen (visible on greys and dimly lit display).My screen doesn't suffer from purple splotches although I think it's a common occurance on amoled displays(considered some what normal). I notice it the most when pulling down the status bar, and scrolling through my feeds in gReader, with white text on a black background at low brightness (mainly at night). The first thing you could do is increase the brightness which helps, but I find changing the color temp has worked a whole lot better.
From my own experience with my first amoled(non-technical), the purple smear is most prevalent with transitions from black to grey/white at low brightness. It even occurs on LCDs(which I myself tried and confirmed on an ipad at very low brightness). It's more widespread on amoled because of the deep almost pure black level.
Now with the splotches your concerned about; I believe this is a drawback of amoled manufacturing and to a certain degree is normal. If changing the brightness or color temp doesn't reduce it to an acceptable level for you, then I guess your only other option is taking it back for a replacement or getting a new device without an amoled screen. If your rooted and your warranty happens to be void, you could try a custom kernel with gamma support(others have reported this helps?).
I apologise for my dumb downed explanation as I'm not schooled on the technical aspects of screen technology. Here is a good write with a more technical background which you may find more informative (Mura Effect & AMOLED).

Well... I was also of tbe opinion that this was somehow a more dreadful recreation of the purple smearing effect. But here, there is no transition from black or even a dark color for that matter. The wideget is all white and if you carefully see the portions where the purple patches flicker is actually the whiter portion of the wallpaper (that is between the leaves). And the rest of the wallpaper is mostly green.
Now, this pretty easy to reproduce on my handset. With that wallpaper and the google now widget in place and a few quick movement between home screens and it can be easily seen.
At the samsung showroom where they display the n9005s (though we can get only the exynos versuon here in India!!! ) I put the same wallpaper and added the google now widget and recreated the exact scenario. I tried for atleast 5 minutes continuously in two shops and I couldnt reproduce the issue....
At the last shop the owner walks in with a Note 3 and his is an Exynos version. And I reproduced the issue with two flicks on the screen !!!

I can assure you that this happens on both exynos and snapdragon models. Some devices have variations in the lower base brightness(0), this can exacerbate this effect.
You going to have to realise this is a downside of amoled screen technology. In the mean time you CAN take steps to minimize it!:
1. Have you tried the app I mentioned above? Download it and set the White Balance(WB) to Fluro. Then see if you can recreate the purple cast.*
2. When you start to notice the purple cast, increase the screen brightness. It shouldn't occur at higher brightness levels.
Do these things then tell me if you can recreate your problem.
*I've found changing the WB is enough and can avoid the Purple smear even at very low brightness levels(sub-zero).

Sorry for yet another long reply !!!
I went to the Samsung service center and showed the display problem. Being within the first 7 days of purchase they readily gave me the certificate for replacement.
So, once I get my new phone this will be the first thing I try. Anyhow, once I realized that this was a problem with all phones I was kinda ready to live with it. As I knew the scenarios where this would be seen and I could just avoid those situations.
But, what got me mad was this :
The first time I bought the phone, there was a permanent rectangular smudge near the back button. If i really clean it, it would become less visible, but with use and finger smudges it would become very much visible again. So, I complained and they replaced the full front panel.
The second time, I was using a pouch (cloth). Permanent marks began appear on the top of the glass where the edges of the pouch used to touch the glass. The same kind - clean it really hard and it would could not be seen but with use they reappear. This was really annoying. So, this time I made a lot of fuss and got them to agree to get the phone replaced. They dint have stock and they ended up refunding the full money.
So i waited for the S5 launch just to see if it was worth a shot. Once it was out, I decided to buy the Note 3 again.
So, the third time I got it, its was wth 4.4.2 and to be frank I was surprised at how smooth it was. I mean the performance was fluid. I was happy. The display issue I could still see. That is when I had done the small investigation regarding the Snapdragon and Exynos versions. Anyhow, as I said, I was ready to live with it. And this time to avoid all problems, I had a Samsung Flip wallet. And guess what, after 4 days, 2 mark appeared on the screen corresponding to the card slot in the flip wallet !!! The same kind - clean - goes - touch - comes back !!!!
4 days !!! Cmon !!! I look after my phone like it were my baby !!! Does this even have Gorilla Glass 3 !!! I used a S3 before this. And i have used a flip cover with it and for the major part I was using a cheap pouch. It dint have a single mark or scratch on it when i sold it !!!
So, am sure of two things : the display issue is gonna be there and the screen is gonna get easily scratched (or get some kinda marks !!!). So, thinking of getting a tempered glass screen protector (I hate using screen protectors !!! )
And I can swear, the display issue is EASILY reproducible on the Exynos version and I couldn't manage to reproduce the issue on 2 N9005s after trying for atleast 10 minutes each !!!
If you havent used S-Note at all, just keep its widget on the homescreen and launch it from there. I should see the problem if it is there. It should be like, the very first time u use S-note, that is, when you launch it, a small video kinda page load.

One more update :
The easiest way to reproduce the issue is to just launch the S-Note app using the widget from the home screen. Just that it should be like the first time use. So, when u touch the S-Note widget, the app launches with a small intro video kinda thingy. So, when this happens, multiple and random patches of purple can be seen all across the screen.
If you don't mind spending 10 minutes, here is what you can do :
If you are already using S-note :
1) Backup your notes from S-Note.
2) If the S-Note widget is already there in your home screen, remove it.
3) Goto app manager and delete cache/data related to S-Note.
4) Put the S-note widget on the home screen (Now it would be green in color with the picture of a note).
5) Open S-note using the widget.
If you haven't used S-Note at all :
1) Add S-note widget to homescreen if not already present.
2) Launch S-note using the widget
You should be able to see the purple patches right away and very much easily.
Now the update is that I visited 3 more Samsung showrooms and tried to reproduce the issue (using the above mentioned method) on the handset on display there (which are N9005s). THE ISSUE IS NOT SEEN !!!
I can say with utmost confidence that the above steps would reproduce the issue in the Exynos versions (Well, after checking on 5 Exynos devices ). If someone with an SM-N900 could verify this, it would be really helpful.
I can post a video once I receive my replacement device.
I am seriously considering suing Samsung !!! Not for giving me a handset with a AMOLED display that has some inherent issues, but for :
1) Showing something in all showrooms across the country and selling something different all together.
2) Having this issue just on the Exynos versions and not on the Snapdragon version.
3) The glass getting marked so easily even though it is supposedly Gorilla Glass 3.

Short answer: I tried what you said and I couldn't reproduce your issue!
I can quite easily produce the purple smearing but not on the S-note intro video!
Maybe your not going crazy.?
On a side note?, I've had a Note 2 in my possession and apart from some lines, which can only be seen on certain grey backgrounds, it doesn't suffer the purple smear problem(Exynos one I tried didn't). If this issue continues to drive you up the wall, and considering all N900s you've tried exhibit the same issue, maybe consider a Note 2 (DittoNote3 ROM?) or import a N9005.
Alternatively, rally together all the disgruntled N900 owners and sue the pants of Samsung.?
Best of Luck either way.

Well... First of all thank you for spending some time for that...
And as soon as I get my hand on my new phone, I will post a video so that you (and I ) can be absolutely sure that I am not going crazy
And I would definitely luv to have an N9005 but i wont get one under warranty here in India I suppose !!!
And about suing Samsung... I am seriously considering that and I would be talking to a lawyer tomorrow just to confirm that I do have a valid case and it wouldn't be just a waste of my time and my money going behind this....
And yeah, lemme see if I can get a few more people behind this with me....
Anyhow, thanks a ton...

Im also using exynos version but I didn't face any of the problems.Maybe New versions have tgis problem

Screen feedbacks/issues

For the current owners, especially for those who are 'extremely' particular about the screen, do you guys any screen related issues?
I've been with the Galaxy S1 and S8500, both devices used the first generation SAMOLED screen and I never had any screen related issues on both devices but as of late there's been a lot of screen issues ( mostly quality control related ) on the Galaxy S2, Galaxy Note and Galaxy Nexus..
To name a few:
- faint but visible horizontal/vertical lines visible on white/grey images
- green/blue color tint when the device is tilted with in just a few degree's
- uneven screen brightness
- suction cup rings
- blotchy/spotty blacks, you can see darker or brighter spots when the screen is displaying an entire black image - All Tab7.7's have spotty blacks, if anyone has a screen w/o spotty blacks please post it up here, it would help a lot of people.
I owned a Galaxy S2, replaced for a total of 7 times all had different screen related issues and I decided to get a refund for and got the G-Note when It came out, already had 1 screen replacement which resolved the lines issue but other screen related issues took its place, still waiting for the 3rd screen replacement to arrive and also processing a refund if they are not able to fix it.
I plan to make the Tab7.7 as my primary media device ( please spare me the 'get a plasma tv defense' ) and a web browsing device so screen quality is very important to me and most of the time it will be used at 0-10% screen brightness in a dark room (bed room).
Using the Tab in a totally dark room is nothing considered as 'extreme conditions' just because not everyone has the same usage pattern does not translate to 'extreme conditions only' situation.
Id like to ask a very honest and objective feedback from the current owners, I also understand that as of now only a few have this device. Testing in a dark room or with minimal ambient light is preferred as reflections can really skew results.
For anyone also wanting to contribute check the following images on your Tab 7.7 and put it in full screen and see if there are any uneven shades,lines or anything to report about.
This thread will get more exposure as the Tab 7.7 is slowly rolled out around the world. I would like to restate that this is purely an objective thread and not the subjective 'i dont see it in normal use' because not everyone has the same normal usage. Its not to say that all of the Tab7.7 screens are defective but Id like to see how wide spread the issue is based on XDA-Developer members. Again people, objective and not subjective.
EDIT:
For now it seems that I've gotten enough feedback and expect the very same issues from the Galaxy S2, Need a huge amount of luck for the purchase on my end.
EDIT2:
We need someone who claims that their black screen output is very uniform and does not have any spots, so far nobody has posted yet but we do see claims but these claims are not enough, for the sake of research anyone with an screen with no blotches or spots on black post up.
EDIT3: (Feb 19 2012)
After checking out and screening a total of 15 units from different stores and different dates, I've managed to see only 2 units with 'acceptable' screens. I say acceptable because I am expecting the grey rendering to be as good as on the Galaxy S and S8500. I will be getting one tomorrow but it still has a visible darker top part and lighter bottom when rendering greys.
The very common issue I've seen is a visible thick vertical/horizontal lines on the screen when rendering greys and either a yellowish or greenish discoloration at the bottom and some reddish bleeding on the edges ( mostly top ) I dont think a screen that can render greys on the Tab7.7 exists for now but Im sure it will be possible 6-8 months down the road when screen production gets better.
Different shades of greys are my objective way of testing the screen quality as it easily cuts down the time needed to do so, if a certain screen passes my objective test I goto the subjective test, Load up Thumbkeyboard and use the split lay out with the ICS theme and observe if the shades on the letters from Q to P are the same, some screens that fail the objective test actually produce good results on the subjective test, while others really give out a very obvious discoloration, also all of my tests are done with 0% brightness since thats the brightness i will be using 90% of the time, as the brightness ramps up these discolorations become less obvious.
EDIT4:
Anyone wanting to set here my suite of grey test images
http://www.mediafire.com/?hfxjz8nhymc4h4d
Crucial images are the grey-15 and grey-25, test in a room w/o any directly light or reflections from your face. 0-33% brightness.
EDIT5:
Why grey images, why all this specific settings that require planetary alignment and a virgin sacrifice, read on:-

I've had mine for almost a month, no burn-in issues, Ive been using the Tab almost in portrait mode and stopped using Honeybar just to see how fast the burn-in kicks in, nothing what so ever.
I cant judge if its visible in normal use or not, unlike others I dont assume how a screen issue looks like unless I've seen it or at least pictures of the issue, this has always been the source of many arguments in forums, people just assume all screens are created equally and just because they dont see the exact same issue on their end they actually become more aggressive and hateful and they tend to find the need to keep defending the product. What gives?
Companies always add a cost buffer to cover for returns and that is usually with upto 3 returns, but complacent people just accepting obivous defects are also the cause for this level of quality control since Samsung can now get away with it, especially that some people are false advocating that there are issues thats normal to AMOLED which is incorrect.
I havent used my Tab yet as an ebook reader so Im not exactly sure what they are experiencing but the pictures posted paint a clear picture, It can be annoying at times I suppose and when a product is marketed for its great screen and deep black levels, should anything less be expected? I mean personally coming from a Galaxy S which had none of the screen issues you've mentioned, the Tab7.7's screen should be expected to be better in every single aspect, right?
I've been quite active in this forum and I haven't seen anyone report multiple exchanges yet, I didnt even exchange my Tab yet.
I dont know who you are specifically referring to but I also use greys as my test images, let me give you a little more perspective incase you made a 'selective reading' in regards to this issue.
Grey colors easily allow you to check if your getting a quality screen or not, they can easily show those lines and discolorations with out the need for using multiple test images, they give you objective results especially when your buying the device but its not very conclusive since the store light will show a lot of reflection on the screen.
Testing at 0% brightness in low light environment is also ideal for an objective testing to avoid any reflections that you might see hiding these flaws, but if one exclusively uses the device in a very bright environment then this step can be skipped.
And this is the real world perspective:
This is the original grey image:

"lightbox_close": "Close",

}
and it should look close to that on the tablet.. For comparison, on my Galaxy S and my former Galaxy S2 can render this color perfectly.
not something like this:
one side is darker, visible lines, dots, circle marks.
You can argue that it only affects greys but it does affect a lot of things you see on the screen and to a certain extent like this:
and when we flip the tab over we get this:
Ignore the moire, notice that one side is darker than the other.
This is how the original frame looks like:
Sure not everyone uses the Tab7.7 as a media player, remember those visible rings and spots above? Check out the attached images.
This is because reviewers hype up the black levels saying its totally black and some internet articles say that AMOLED is in an 'off' state when displaying blacks which gives us the false information and relatively ruining expectations, my first samoled device was the S8500 (Wave) and the blacks were great, no blobs or spots and it had a very faint glow, that was the foundation of my expectation which was further reinforced by the Galaxy S that gave the same results. Others may have started with the Galaxy S2 and the expectations set by reviewers so they ended up returning their devices. On my end I returned it for the yellow tint, which the technician also confirmed that it was very visible and during that time there was nothing they can do.
Sorry for the wall of text but I felt that I should be explain this thoroughly as I am very affected by the screen issues and I am very vocal about it and it did get things done on my end.
TL;DR
Bottom line is, its a $700 device with its primary feature as the screen which is advertized,marketed and specified to have the most vivid, crisp, sharp and clear images. Others are reporting that they dont have any screen issues-what-so ever so why should someone else for settle anything less?

the 77 has same screen as the note... but it's brightness more even across the screen.. the only problem you will have is it's size... since you're coming from Note.. you might find it hard to justified it's size... like bringing it with u anywhere.? when jogging?
I am now using my old trusty ipad2 ... which I can type like a breeze...
like I said 77 has better amoled screen that early Notes...

Erm, wrong...
The Note is a PenTile display. The 7.7 is not.
The Note's PenTile arrangement uses 8 subpixels per 1 pixel.
The 7.7's SAMOLED Plus display uses 12 subpixels per 1 pixel.
I won't be brining it around for joggin of that sort, its gonna be my primary media device so it needs defect free from those random manufacturing faults.
It might be too early to ask this as probably the user count in xda is pretty small.
I'm returning one of this beacuse when reading in a dark room there are serval visible rings and spots darker than the rest of the screen.
You are only able to see it when you have a grey or black background and your eyes are adapted to the darkness.

This device probably isn't for you, yet.
I just got the 7.7 and have issues. The brightness is a bit brighter along one side, and I have the dark spot issue, this time in the form of dark circles, equally spaced (probably from the glass handling suction cups or something)
On the bright side, at least I don't have any bad pixels ;/
BTW a good app for testing is the simple "Advanced task manager" app, it has a dark screen near black and these blotches are visible with this even in a room with some light.
I used my galaxy tab 7.7 for almost a month and i must say , the dark circles are truly annoying especially when you watch movies with dark scenes in a dark room with low brightness.You can hide the dark circles by increasing the brightness but it is a simple waste of battery life and its really bright in dark room. I also noticed screen burn in for the wifi and battery icon, i used my 7.7 on zero brightness since day 1 and screen burn-in still persist after 3 weeks. Good way to see the dark circles is by simply turning off the tablet, the tablet will "glow" with the dark circles after the samsung logo is gone.

My old and new one have these rings. I'm guessing its glue or something bonding the screen to a backplate. Or an imprint of a backplate on the screen.
In any case I think this is not a problem or defect. You really must be in total darkness and viewing a black screen to see it. And even then its very hard to see.

You are only able to see it when you have a grey or black background and your eyes are adapted to the darkness.

I just got the 7.7 and have issues. The brightness is a bit brighter along one side, and I have the dark spot issue, this time in the form of dark circles, equally spaced (probably from the glass handling suction cups or something)
On the bright side, at least I don't have any bad pixels ;/
BTW a good app for testing is the simple "Advanced task manager" app, it has a dark screen near black and these blotches are visible with this even in a room with some light.

I used my galaxy tab 7.7 for almost a month and i must say , the dark circles are truly annoying especially when you watch movies with dark scenes in a dark room with low brightness.You can hide the dark circles by increasing the brightness but it is a simple waste of battery life and its really bright in dark room. I also noticed screen burn in for the wifi and battery icon, i used my 7.7 on zero brightness since day 1 and screen burn-in still persist after 3 weeks. Good way to see the dark circles is by simply turning off the tablet, the tablet will "glow" with the dark circles after the samsung logo is gone.

Thanks for the heads up, It would seem that the darker spots are quite obvious since the screen is bigger, I also had those spots on some of my Galaxy S2 replacements and I found it very unacceptable and the same with my Note.
When I was testing at the store which had the usual store lighting one unit had several visible lines in greys while the other one only had 3 lines just in the middle.
For the uneven brightness on the screen, Im pretty sensitive to that.. when I saw the HC task bar in landscape mode I immediately noticed a difference in brightness but only 1 of the 2 exhibited the issue.
The screen burn-in is a concern as Im getting the same feedback from friends who bought the unit just last week!
I understand that not all screens have this issue but the chances of getting an out of spec screen might be pretty high, wish they brought back the same quality control when the Galaxy S initially came out, which had none of these issues what so ever.

My old and new one have these rings. I'm guessing its glue or something bonding the screen to a backplate. Or an imprint of a backplate on the screen.
In any case I think this is not a problem or defect. You really must be in total darkness and viewing a black screen to see it. And even then its very hard to see.

It is a defect and a very bad one, also the visibility on this is not the same on all units. I have a suction up ring on my Galaxy Note which is visible at the 'service center lighting conditions' which the tech also saw the rings. Several pictures of this issue also posted on the various Galaxy S2 forums here in XDA under a well lit condition.

Seems like it until screen yields improve or I get a chance to get one w/o any of these out of spec issues.
No screen is perfect, not even the ipad screen.
Ihave a galaxy s2 and rememeber hearing all the burn in worries last year. Almost a year later now and i dont have any burn in.
The only issue ive noticed is that some pixels on oled can have a slightly differrent brightness than others due to the nature of oled. Yes my s2 has a tiny amount of pixels like that,
But you have to look at it at the wrong angle with the wrong amount of ambient light with the wrong colour on the screen to notice it.
Yes a larger screen is likely to have more issues but if it was an ips screen then we would no doubt all complain about backlight bleed.
My advice is stop looking for problems with it and enjoy your tablet otherwise you will never be happy with it !

Like what you said, no perfect screen but there are some screens that are made better, A year of usage with no burn-in is fantastic! Some are getting it as early 30days from purchase.

Yes to certain degree there are but they should not be noticeable to the naked eye, if its noticeable then its purely a quality control issue.

Well that depends on the usage, Im not pushing my own usage to anyone as I believe not everyone watches movies or browses the web on the tab7.7 with close to 0% brightness and in total darkness. My usage revolves on that so there are no special conditions on my end. I hope this is understandable.

I do not look for these issues intentionally and I see them with my normal usage, thats why I intend to research first before taking the plunge. But I understand I might have a higher standards that others but thats just me, I want to get the most of my purchase or not purchase at all.
Long story short, all the screen issues I've found on my Galaxy S2 was due to normal usage including the yellow tinting and darker spots which annoyed the heck out of me considering the cost of the device. On the Galaxy Note I've read about the all the screen related issues even on the video issue and still said to my self 'these things should not be noticeable in normal usage' but i was wrong. So this time Im taking it slowly but I already know what to expect. But I do understand what you are trying to say.
EDIT:
I dont want anyone to mistake this as a witch hunt, I just want to know what to expect, acceptance is easier when expectations are set.
Yes, there will never be 100% perfect screens. We'd all be constantly returning devices and not actually using them because of some "defect".
I've had my S2 since it first came out in May 2011. No problems with burn-in or colour shifts. I don't expect my 7.7 to have problems either. I'm not concerned that some "defect" will manifest itself under some extreme "only if I go looking " condition.
I'm enjoying using my S2, 7.7, and Transformer for what they are - mobile devices that provide communications, entertainment, and information.
Agreed I can also accept defects as long as I dont see them with my usage. Example between my SGS2 vs Galaxy Note which shared a common issue on the darker spots but it was more obvious on the SGS2 since it was a horrible pattern while on the Galaxy Note its tiny and multiple spots.
Every defect is different and we should not all assume that they are all acceptable to everyone.

May be for you it's an extreme situation, but in my case, I bought this tablet for reading ebooks at bed (among other things) and I use white text over black background, so I am in that "extreme situation" on a daily basis.
I also have a Galaxy Nexus and that screen also have one line and some dots, but since my usage pattern is not the same it don't bothers because I really dont see it. But in the case of the tablet, I had to convince myself that I had paid a big amount of money to receive a screen with what for me is a defect.
I was the owner of a Huawei Ideos S7-105 (I now miss it) and appart from the battery and several other small annoyances I was pretty happy with it, I paid 150€ for it so I got what I paid for, but the 7.7 costs 450€ so my level of exigence is higher.
Sad thing abot all of this is that the other tablet that could be an option (Xoom 2 8.2) seems to bee plently of issues as well.

This is always the case, people who dont have the same usage pattern nor with the same issue will never understand. But its been my understanding that this is already 'common' (but not normal) among amongst the hd samoled and samoled plus.

Yes the other alternatives that I've been looking are also riddled with issues, come to think of it only samsung has the least issues based on my research.
I've seen the concerns on other AMOLED devices Earlz mentions as well.
It's not a deal beaker but you may want to keep a LCD device around for reading at night.
No use exchanging numerous times hoping for a perfect screen.
Right now while AMOLED is a very dramatic screen tech
but it's not at its best with low brightness levels,
and certain test patterns / images reveal other side effects .
For reading in the dark a screen like the iPad 2's IPS LCD is probably a better choice.
It offers a very low brightness level with consistent results.
I think the key is to use AMOLED devices where they perform best,
at higher brightness levels during the day.
In that scenario if you hand a iPad 2 and AMOLED device
to the average person they will be floored with the AMOLED screen.
I don't have any issue on low brightness level.
I always operate my 7.7 at ~0-20% brightness.
Did anyone test the screen using the screen test apps? I tested mine and I have yellowish patch at the bottom part of the screen. It's only visible in dim grey. Luckily there is no dead pixel but my screen start to squeak a little when press at the bottom corner. The quality control is really bad. I'm waiting for a engineering revision before going for warranty claim. I must say I'm disappointed.

There's been a few reports from here and another forum that the screen seems to squeak or dislodge a bit on the bottom corner.
@SonicTab:
I went for an amoled screen beause it's suposed that when screen is black pixels are off and there should be no light emiting so in my case, when reading in the dark I should only see the text, and not a bluish black background as every other LCD based screen
@GOF007:
You are either lucky or do not use the tablet in the same conditions as I do. Did you test it viewing one of the pictures in the first post in a dark room?
I really hope my case where just bad luck and be given another tablet whitout those screen issues, or at least with something less annoying.

Yellow tint on S4 screen

I have this annoying yellow tint on my S4's screen, but disappears when the phone is tilted over 45 degrees. Is this faulty ? Shall I return it ? Or is there a way I can fix the gamma through an app without rooting the phone ?
Brightness set on full
Auto-tone, Auto-brightness disabled

I have this too, interested if this is a defect or just the colour tone of the amoled on the gs4
I have the S2 and it's blue compared to my display on computer, and I don't even notice it unless I put it against the computer display like you did.
Maybe try other display calibration, I hear you can change them.
Ok, been doing some google research on this -
There's always going to be a slight yellow tint to the particular amoled screen used in the GS4. However, to reduce the effect, set your screen mode to MOVIE.
Movie mode provides the best colour accuracy and also white point of the available choices. I can confirm this is the case having just spent a few minutes comparing colour charts to my girlfriend's very well-calibrated iphone 5.
So I would set it to MOVIE. The whites still won't be IPS display white, but then IPS can't touch the beautiful blacks on amoled. Horses for courses. Hope this helps.
@paddlyaz can you provide sources of where you got this info ? -- Edit : I just tried it, all that did was make the display washed off..Yellow tint still visible
It may LOOK washed out to you - but this is an AMOLED display, which is naturally very colour saturated.
If you compare the gs4 to an iphone 5 like I did just now, you'll see that even in Movie mode, the colours are a little MORE saturated than even the iphone 5 has to offer. The tint is a side-effect of this. IPS displays like the iphone may offer truer whites but amoled displays like the gs4 destroy them in terms of saturation and black levels.
It all depends on what you prefer on a phone.
In terms of the GS4, some people find the 'dynamic' and 'standard' modes vibrant and eye-pleasing - but they're not at all accurate and will exaggerated, innaccurate representations of your photos, videos etc. I have one photo of me in a yellow jumper (fashion mistake I know). When I have it on 'standard' it looks like I just came back from a two week holiday in Chernobyl. In movie mode, it looks exactly how it looks in real-life (i.e. still disgusting but accurate).
Here are a couple of links that describe it more:
http://www.gsmarena.com/displaymate_tests_galaxy_s4_screen_gives_it_the_thumbs_up-news-5928.php
http://gizmodo.com/5995376/galaxy-s-iv-display-shoot+out-how-does-it-compare
I wish I have another camera to show you the difference between my iPhone and S4 ... The iPhone's screen is bright white compared to the yellow tint on my S4. If this is a "feature" then it's not really efficient now is it =\
Maybe there is a way I can manually edit the gamma, this should fix the problem I guess. Or just exchange it for another one.
did you read ANY of my post?!
It's the trade off you pay for having perfect black levels and saturated colours.
The only way you're ever going to see perfect whites is if you get an iphone/htc one - e.g. an IPS display.
But then you're going to be stuck with 'blacks' that are actually grey. And that SUCKS.
People have differing opinions on which trade-off they'd rather have. Personally I'll take a slightly 'warmer' screen in return for having deep, inky blacks.
Hmm I see, so the display type is the reason why the yellow tint appears eh ? Interesting, thanks for the links too, going to check them out.
all screens will be slightly different from each other - but yes, amoled screens will almost always have either a slight YELLOW tint, or a slight BLUE tint - in other words, a slight exaggeration of one particular tone. If you have the time, do a google search and you'll see this was a common 'issue' flagged up on both the gs3 and gs2.
Your best bet is to do the following:
-set screen mode to MOVIE
-disable 'auto adjust screen tone'
-disable auto brightness.
You will never EVER see perfect whites on an amoled screen, and anyone who tells you they have them is lying out of their arse. Most reviews for the GS4 and also in the articles I linked you state that the GS4 is the most accurate amoled screen so far though.
If still disappointed, your best bet is the iphone5/htc one/nexus 4 etc
I think having an exaggerated blue tone is better than a yellow tone, in my own opinion.
Anyone else having this issue ?
I noticed this playing around with the S4 in the store. Still, much better than the S3 white point.
bad yellow tint
Hi everyone,
I received my s4 last week and found it yellowish as well. I have read everything regarding the screen yellow tint and the fact that it's because of the type of screen. I was going to give up but my girlfriend got one today as well and the comparison is very clear: her whites are so much better!
I have tried to take photos of them, and it looks greenish on the shots but you can see the difference. FYI the screen are both using the same settings: auto brightness off, brightness at the maximum, both screen mode in adapt display (I have tried the movie mode without noticing a change).
Mine is on the right if you couldn't see. You can clearly see the difference in the colour and the quality of the screen. I also noticed that the viewing angle are way worse on mine, the phone takes a greenish colour.
Finally I have very strong smearing/ghosting as soon as the screen background is black. For example when I am in the settings, if I scroll up and down, the thin lines separating the sections actually disappear whilst the menu scrolls. The thicker separator get a purple line until the scolling stops. Once again, the smearing on my girlfriend's phone is existant but much less strong. The thin separators are still visible even while the phone is scrolling.
I am definitely bringing it back to the store tomorrow. I am very disappointed with the screen even though the phone is great. I wouldn't change for a One, just for a good one.

I had the same yellow tint on screen and tried a few different firmwares thinking maybe its a software issue but nothing fixed it.
Picked up a new s4 last night and this one is perfect. The thing I noticed is the new one is assenbled in Vietnam and the old one
was assembled in China. Over all the build quality on the new one feels much better along with audio quality.
Maybe a quality control issues in some factories

You'll see it when you pull the battery, there should be a sticker there.
I am located in Toronto and we dont have any samsung stores here

I looked at mine and it says made in Vietnam... But I would agree to say that there is a problem with quality control overall. My guess is that they need to produce as much as possible to avoid any shortage. I had the same problem with my Note 1 and could be bothered to change it, this time I won't let it go.
I will keep you posted.

I had to go to another branch and thankfully they had a model with a white tone screen. I compared it there and they did indeed see the yellow-tone in my phone. I am getting a refund soon, it's not really worth all this trouble i'm fed up of the customer service experience with Samsung.

[Q] Note 3 Uneven Screen Color

I know there are a few different threads about various screen concerns, but this one is specific to color distribution. Sorry if this belongs elsewhere.
I attached a picture of the Note 3 screen without any screen protector while on the dark gray color from the LCD Pixel Testing app. Apologies that the uploaded picture isn't rotated properly. The bottom-right has a purplish/pink tint to it and the top-left has a greenish tint. It's not the camera angle/picture because I took another picture of it from the same angle, but upside down and the coloring moved accordingly.
I also took a picture of the Note 2 under the same conditions to make sure that this isn't normal for other screens, and the Note 2's screen was much more consistent. I've experienced uneven color distribution on the Samsung UN46B8000 TV, but not on a mobile device.
Does anyone else have this type of uneven screen color on the Note 3?
Thank you!
Im not sure why is this happening. Im now on my third replacement and every one has this hue or tint in different parts of the screen. Im not sure if its fixable but I gave up on samsung. I just hope it goes away after some time.

Thanks for the reply. I'm going to check out display models and see how the uniformity is. If they are worse than mine, I'll keep mine. Still, I think that Samsung should really work on this. I've compared it to the Note 2 and S3. All have better uniformity than the Note 3, which saddens me as I was really looking forward to this device.

I spoke to one of the tech guys at my work and he said it could be a power issue. The power source could be coming from the upper-left corner and it gets weaker as it goes across the screen, which could explain the gradient-like change in the display. If the pink is at the bottom-right for all our displays, it could be the explanation.
We looked online for a proper teardown, but we couldn't find one that showed where the screen power originates from. I don't know about this because I'm not sure if full/more power would result in a greenish-blue hue. The only evidence I can think of that supports this is that the Note 2 and S3 were overly greenish-blue in tint over the entire screen.
Does everyone affected have greenish-blue on the top-left that fades into pink on the bottom-right?
just tested mine with the app i got no tint or diffrent hue .. I've tested it on AUTO, Manual low, high brightness settings..
I have these problems since I own AMOLED devices, and that is now for quite some time (see sig.)! Me too had to exchange each device a few times until I got some with a almost perfect screen! On both N9005 I own so far the lower screen side is darker, although there are other significant differences between the two screens: the one of the second device is much more uniform! plus no1 has sharp pitch up in gamma on the leftmost 5mm over the whole side (maybe this screen has been cut out from the edge of the mother-substrate: the more from the center the better, due to principles of metal mask lithography)
I've done a few posts in regard to this in the past, if interested use the search function!

Another problem I have: When CUP is on medium to heavy load, screen brightness and contrast start to go up and down slightly each few seconds on all brightness levels, even on manual and lowest brightness! this happens on both devices, although here the first one is a little more stable! for me this happens always when in gallery for example, due to CPU load because of media scanning... Seems to be some load or thermal brightness throttling mechanism implemented (guess: in some part of the kernel)...

I'm happy for you. For me, I gave up and bought LG g2 and I'm so glad I did. I just love this ips screen.
I'm wondering if it's there is edge LED lighting and the screen is just uneven.
My first one was like yours which seems very bad. Took it back got a new one, this one has the issue too, but its not that visible. I wanted to take it back again, but then i saw a guy who took 3 Note 3s back and the last one was the worst. So change it until you find one acceptable and next time wait a bit until Samsung gets better QC, or hope for another player on the phablet market.

It's probably not as bad as I make it sound. You can only see it if there isn't any light in the room basically. I took a screen shot of the battery status menu and cropped it to the all "black" part and put a black dot on it. In a totally dark room (doesn't mater what the screen brightness is) see if you can find the dot. It's pretty small you have to zoom in a lot. But using this image I can see the uneven lighting on the screen. If there us ant kind of color displayed though it's totally invisible.
I'm kind of worried about getting one that's worse too. that's what's got me not wanting to deal with it. A lot of them down here have been getting returned to best buy and Verizon because of a signal issue or battery drainage problems.

Nope. Obviously. ?
So I returned the first one and got another. This one is better but there's a big dark band that goes across the middle. It's not as pronounced as the last one though. -__-

Try this in a dark room. Using Display Tester app test card Grey #808080 and put the brightness in the screen tester to as low as possible as well as your phones brightness to low as feasibly possible. The check out the lower half near the home button. You will see it being slightly different and darker. Both mine and the wife's do it. Her's possibly a little bit more pronounced than mine. Normal, as I never notice it during day to day or night time viewing. Point being I have to go out of my way to find this so called issue.

Try this in a dark room. Using Display Tester app test card Grey #808080 and put the brightness in the screen tester to as low as possible as well as your phones brightness to low as feasibly possible. The check out the lower half near the home button. You will see it being slightly different and darker. Both mine and the wife's do it. Her's possibly a little bit more pronounced than mine.

My first one was like yours which seems very bad. Took it back got a new one, this one has the issue too, but its not that visible. I wanted to take it back again, but then i saw a guy who took 3 Note 3s back and the last one was the worst. So change it until you find one acceptable and next time wait a bit until Samsung gets better QC, or hope for another player on the phablet market.

i had same issue i replaced 3 note 3s then in white color there is no tint no screen issue..n checked 6 phones on shop..u r lucky if u get 1 phone with gud screen among ten phones..9 will be faulty and one will be gud....but my shop keeper is a nice guy..but really samsung should fix this issue.
..
people will complain about hardware issue after some time..when they will compare note 3 together..
coz i have too much experienced in note 3 replacement.
i had three note 3s n900 and n9005.And checked 6 note 3s...so trust me..some device perform gud some laggy..

can confirm this! and it was the same on note1, note2, ... on basically all amoled devices i owned from samsung so far!
the "problem" is the manufacturing process of the amoled screens:
they were cut out of a wafer. in the process of exposing the wafer with a light source through a FMM (fine metal mask) the exposure is not evenly distributed over the whole wafer. the more from the middle your screen has been cut out, the better it is! the gradients (down side darker, right side darker, ...) are due to the gradient light exposure of the wafer before cutting!
so it's all luck of the draw: atm i have one (!) decent screen out of 5 devices! the bad thing is: on this device the thermal throttling is comparable worse then on two of the other devices i have, but on these the display is very uneven!
so it seems to be a hard task to get a device where a) the screen is perfect and b) there are none of the other known problems (wobbly button, thermal throttling, noisy camera, ...) present!
thank you samsung!

Display Issues Thread

We can discuss display issues here. Here's my situation:
Let's be clear: MOST display have problems. My iMac I'm posting this from is tinted yellow on the left half and magenta toward the bottom right corner; my Nexus 7 2013 had edge light bleeding; 3 iPad minis retinas had edge yellowing; I returned and exchanged my way through 5 iPhones 5ses and 5 Nexus 5s before I found one without display problems; etc. But these faults are subtle enough that the general population isn't sensitive to them, or else they mostly don't care.
Sure enough, my Note 4 has display issues. I'm not sure if this is Mura Effect stuff or just bad quality control. Check it out below.

The picture above doesn't do it justice, it's a lot more apparent when you've been using the actual display in real life for awhile. Also disregard the scan lines. But notice about 1/3 of the way from the top, there's a subtle horizontal line where the display below it is more gray, and more yellow above it. And if you divide the display diagonally from the bottom left to the top right, then the left half is tinted yellow compared to the right half, especially toward the upper left corner of the display. And the entire right edge of the display is tinted magenta, which is more apparent toward the bottom right.
Above I used the Note 4's Screen Write ability to document the imperfections as I see them.
Don't get me wrong, the display is nice. But I will likely have to flip through several devices until I end up with a good display. Are you guys noticing some Mura Effect problems, or other problems? Talk about them here.
PROTIP: to see the Mura Effect imperfections on your Note 4 display, grab this image and view it in a pitch black room and manually dim the display to the lowest level.
All I see is someone who is a perfectionist
So far I haven't had a display Issue. I keep at full brightness at all times.
Anyway, I know people are having issues and I am sorry you are too.
I got lucky I guess
From the BadAss Note 4
I dont notice this at all on my white note 4. Even if it so faint then the difference is neglible. Its not really worth the trouble going through 10 different devices just to get rid of this effect. But i turned off all lights and its night here so no outside lights and i see nothing at all wrong with my display. i also dont see anything wrong in your images either.
OP def has issues.
I see grey lines on the image that I'm not even sure is an artifact of the display or what you purposely have showing on the screen n I do see the slight greying 1/3 the way down, but again, what do you have displaying on the phone to represent this and how do you know that image itself isn't creating the artifacts, not the display?
No way YOU get that many lemons... either you're too picky or your method of testing is flawed.

The gray lines are from the camera, I edited the OP to reflect that. The image is just a plain white image, the same one i used to demonstrate display problems with the nexus 5 earlier this year. It's not that i get unlucky, it's that displays usually have problems. The apple store manager let me replace my 5s to get a good one because he acknowledged the edge yellowing and that colors were inconsistent even across the 10 display models. He told me outright that displays are calibrated within certain limits, and every display will appear differently, but that edge yellowing is an actual problem and he could see it after I pointed it out. I can't be blamed that most people aren't bothered by these problems, or that they're too insensitive to notice them. And again, the pictures don't do it justice...we're talking about a display you hold in front of your face live and stare at for hours daily.
On my current Note 4 what i mainly notice is that the gradient, where the yellow tint of the upper left gradually blends into the magenta of the bottom right. For me that's noticeable constantly. I can't make myself not see it, it's pretty apparent despite the image in the OP not showing it off well. As for the horizontal separation between the milky upper 1/3 and the gray lower 2/3, I'm only actually aware of that whenever i scroll, because eyes are made to notice contrast so it becomes apparent whenever my eyes are tracking something as it passes that border.
Nope. Perfect display here.
my problem.... and a big one, i cant stop staring at it. lol
Starting to have buyers remorse, tempted to consider a 6+ if stores dont have stock to exchange this for soon. Its so gross, this is all i see whenever im using my $830 phone with the "best mobile display ever" according to display mate:
Also, not necessarily a problem just something i noticed, this display gets SUPER bright in direct sunlight (its max brightness is only allowed on auto brightness, you cant set it there manually). That makes all colors super washed out, its weird, but so far not a problem. What im writing about here though is something I've never noticed on an lcd displays: whenthe note 4 SAMOLED is at this max brightness because youre viewing it in direct sunlight, if you use your finger to cast a shadow on the display, it makes this really bizarre inverted shadow effect. Try it out, its kinda crazy!
Hey am having tmobile send me new device because of this issue,for me it was really noticeable in landscape mode browsing Web at night once eyes start to adjust to screen brightness, I can see on mine were one side is whiter and the other a greyish purple hue.
---------- Post added at 10:12 PM ---------- Previous post was at 10:11 PM ----------
My note 3 did not have this issue.
It's highly unlikely that you're going to score a unit with absolutely consistent white balance across the display. I haven't had an AMOLED screen that doesn't have it to some degree, and i've had many. Even my Note 4 has it, but it's very difficult to see unless you're really looking for it.
When I first got the S4 a couple years ago I got a unit that was so bad that when looking at the keyboard in landscape it was clearly 2 totally different colors on each side, but I exchanged and got one that was much, much better, but still not completely 100% even. So you might try an exchange if you can, but don't expect absolute perfection. Most displays on most devices will have some degree of imperfection if you look for it, whether it's white balance issues, back-light bleed, uneven brightness etc etc. An AMOLED panel is still likely to give you a better overall experience than a comparable LCD.
As many others have said in this forum, just try not to look too hard at the finest details ("mura" effect for example)...it's still mass produced hardware. If your screen is that noticeable though, exchange it.
I had this problem with my black note 4, my wife has the white one so it was clearly there when put side by side, tmobile said it was ok so i had to take her phone the next time and then they said it was bad. Something interesting, the white ones seem to not have this problem.
Yea got shipping info for new device today,should be here Monday,which ever one has least defect I'm gonna keep.

my gf has a white note 4 from vzw .. i have a black note 4 tmo.. the only thing i notice between our devices is that hers has a slight yellow tint but her display is a little brighter.. i have seen this with my old iphone's if i ever had to get a warranty replacement form apple .. the replacements always had a yellow tint but were brighter ..
so far no issues with my note 4 .. i got lucky this time around :good:
Lol.... I think I beat all of you. This happened a few hours ago while I was using Yelp and Google Maps to find breakfast. Needless to say I'm pretty upset right now, but thankfully I have my Note 2 still, so at least I have something to use until T-Mobile helps me out. I'll be going there in a few hours to talk to a rep to request a new unit. Hopefully they don't try and **** me because I bought in via T-Mobile's website versus in store or because I don't have Jump anymore.

Dude is that the way it looks ALL THE time? Dude GO WITH THE WHITE ONE. I know I am I have the charcoal black and seems to be a bigger problem with the black ones than white I went in to the tmobile store and they had a white and black one. The black one was the same as mine (bluish white/warm color) compared to the WHITE note 4 the white looked great. Sure the black seemed brighter but I think that's what hurt the device in the first place. Sending mine in today or tomorrow already set.

Nick you should save yourself the hassle and just call tmobile customer care. The lady right away told me to send then my phone and as soon as they got the tracking number they will send me a new one. I'm going with the white if I can.
Sent from another Galaxy! Note the difference!
I exchanged mine 2 times because they had dust under the screen . Too bad I didn't check the screen uniform last time.
Anyway I'm on my 3rd Note 4. I don't have yellow/blue/purple tilted part but the white is not uniform as I can tell the top half of my screen is a little bit dimmer. It's something that an average user wouldn't notice but I do because I'm extremely picky. Anyway my dad's note 3's screen has uniform white so maybe you can score a perfect amoled screen but then maybe you'd end up with another problem like dust or dead pixel.
Sometimes I hate myself for having such good eyes lol

My black Note 4 also has some issues with the screen uniformity. My right side has a pink hue as described above. I don't have the yellow tint on the left. Also under direct sunlight the screen creates a strange effect, it looks like the colors are inverted. If you place your hand to create a shadow over the screen then the colors look correct without the inversion, it is a very strange phenomena. I am trying to decide whether to exchange it for a white one or get another black one.
Are the white version somehow better in quality control?

Mine was looked like this. And everyone in the BestBuy from where I got this said this is NORMAL. Fortunately I could able to get a replacement from the other BestBuy. The new one is still not perfect (it looks similar to yours), but I can live with it since I don't want to send it for Samsung's Warranty service.
(My local BestBuy said they can exchange the smartphone for only one time. If I have a problem with the replacement, I have to send it back to the manufacturer for repair. I couldn't find this from policy in BestBuy website, but that's what they said to me.)

[ISSUES] Known issues, discussion and workarounds

Why am I starting this thread?
- To make a proper issue thread, most users are reporting issues on various threads.
- If someone is to buy a S6, or has got a new one, they can resort to this thread for checking their handsets.
- Issues can me major and minor, and considering we have paid a fat buck, we cant settle for less.
CAUTION:
- read this thread only if you want info about your device and for cross checking.
- Once you know your device has any of the below issues, it will bug you forever!! so dont blame me, I'm just trying to be informative.
1 ) Uneven screen, Uneven brightness, Uneven color, Gradient on grays, Pink/Yellow tints:
Common issue with amoleds, Amoleds are manufactured by deposition of various layers on a Substrate (Glass, plastic). Then these layers are exposed to light in a procedure called as "Fine metal masking" . During this process light gets unevenly distributed across the big plate of glass from which our displays are cut. Why does this happen? The technology isnt as mature yet, earlier in 2010, it was worse, now it has improved but not perfect. Due to uneven exposure of light while manufacturing, some parts of the mother-plate do not get equal light and hence we get tints, gradients on grays, and uneven whites (pink tints). The more your display is cut from the center of the plate, the better is the accuracy, the more it is cut from the sides, we get uneven tints.
Here are some images:

(Roflwafflez)
What can you do about this? will this be fixed in a software update?
- NO, no update can fix it.
- only a screen replacement, or a RMA can.
- Replace your device if you cannot stand the tint, or if its bothering you (After all you have paid a lot for it)
- EVERY Amoled will suffer from this issue, ranging from negligible, to intolerable.
The note 3, S4 and Nexus 6 are affected by this issue majorly. Many live with it, some go for replacements and end up in a cycle of RMA's. If your display is tolerable or if it does not affect you, then dont go for a replacement.
2) Color shift at various angles
The display is glass, and it will show some rainbowing to an extent. Color shifts on pure whites are noticable . This does not mean your display is defective, it is just the way it is.
3) Auto-Brightness not working
The S6 shuts down brightness settings at low power to save battery. Make sure you're charged. Still if it does not work properly, check if you have any screen protector or tempered glass covering the ambient light sensor beside the earpiece. To cross check if your ambient light sensor is working properly, use CPU Z, go into the sensors tab and check for the light sensitivity, it should range from 0 to 30 or even more at brighter lights. if it is showing less value or no value, your sensor is not working. Get your device replaced or serviced.
4) Lines on display
Here's something new that I noticed today. If you subject your phone to direct sunlight, and full brightness, there are clear visible lines on the display. It is a manufacturing thing and it does not bother me. I do not use my phone is sunlight. I could not get a good picture, so I drew it in paint to show what it looks like.
Here's a picture:
I dont know how widespread this issue is, but its there on mine, clearly visible on lighter colors like (cyan, yellow) ONLY in direct sunlight. As it is not reducing my usability to any extent, I am not replacing or getting my screen serviced.
These markings look like some techie circuit lines. No display is perfect, there ought to be some or the other thing on it.
5) Flash always lit
This is a well known issue, as of now we cannot do anything about it. Even when the phone is switched off, the flash is on dimly. My guess is, it is the way it is, there is no current leaking into it as the phone removes current from the Motherboard when switched off. So this looks like the flash is manufactured like that, maybe some glowing material like phosphorous, (IDK). The flash otherwise works just fine. To see the issue, go into a dark room and observe the flash area, you will see a faint glow. Here is a picture by tenxo
6) Phone heating up
The phone will heat up on heavy use, it is very common on androids. I did not even needed to mention this issue as its not an issue. I read some people complaining, so I included this.
Androids will heat up. you cannot do anything about it. My Galaxy S3 and Nexus 6 used to heat like a frying pan (45 deg to 49 deg). Even my S6 heats up so much on heavy use, or while the Wifi Hotspot is on. (Lol. Hotspot). Anything above 60 deg is not normal. I have never experienced it, even on over clocking the CPU on my previous phone. The fast adaptive charger will heat the phone up, and it is normal.
7) Regional Locks:
Say, you have brought a S6 which is for some other country. There is a thing called regional locks, wherein you need to activate the phone using the same country sim. Idk why samsung has done this, but it is regionally restricted for activation. Once you have activated the phone, you most probably should be able to use it anywhere else. (Cant say as I havent tested it). How to remove regional lock? No info that I know of in that particular matter. If anyone has anything to share on this subject, please leave a comment as it will be helpful to others.
8) Heart Rate sensor always on?
Uninstall google fit, reboot the phone. Samsung health app has some problem with google fit. Uninstall google fit, and everything will be fine.
9) Capacitive keys always on?
use this https://play.google.com/store/apps/details?id=com.notquiteinsane.galaxybuttonlights
10) High RAM Usage.
Apparently, a common issue. Samsung is really bad when it comes to ram management. It's a known issue that there are memory leaks in lollipop. Luckily software patches will be available soon, try closing all apps or disabling a few Samsung ones which consume ram. For me it is not a big deal as I am not facing any any lag whatsoever in any apps even after such higher ram consumption. The only problem is when apps are switched, the app may force close. Wait for an update, or flash cyanogenmod when it is available. Meanwhile try other stock custom roms in the forum.
Update :
After some minor updates over the last month, I've noticed some improvements in RAM usage. Earlier my ram consumption used to idle around 700mb free, now it's around 1 GB free. I have the same apps, same usage and I've installed more apps over time and still it has got better.
11. Uneven capacitive buttons:
One xda user reported the button backlit is uneven, I do not use the button backlight, it is always off for me. If you notice this issue please report.
12. Scratches on the screen
Scratches are not common and highly unacceptable. If you're noticing scratched screens, get your device replaced.
If you find this thread informative, or if you want to throw a stone at me for pointing out a flaw in your device, you are welcome to hit the thanks button. I have severe ocd when it comes to my phone, and I cant handle noticable flaws.

That's great. Enjoy a flawless phone.
Minor issue here, but me and others have noticed that the Samsung keyboard keeps re-enabling itself making the input selection notification show up in the notification menu. Does these consistently a few minutes after disabling it.
Will most likely be fixed in a future update, otherwise it could be possible to disable the keyboard completely via adb even though unrooted.
I have the tint issue, unfortunately, even after one phone replacement.
Regarding the lines under sunlight I believe it's related to the touch grid? I remember seeing it on my s4 too.

Good to know that my friend. After looking at many of your comments, even I decided not to settle for this tint issue and returned mine. Over here in India, they issue a Dead on Arrival certificate and I need to take it back to the retailer where I bought it from. Since I am out of town, I may just travel over the weekend to get this replaced or send it along with someone who is traveling. Hope the replacement turns out fine.
Annoying issue, which is popular in S5 too. "Searching using GPS" keeps popping up. There are suggestions to reinstall weather app. But none of the suggestions works.
