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",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
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.

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.

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 !

True no screen is perfect, what I am looking for is a quality screen that is with in specification and Im more than certain there are batches of screens that will meet these requirements.

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.

Anyone else experiencing screen color temperature variation between devices?

Just got my 1st replacement Nexus in the mail-the first one was exhibiting symptoms of a non-responsive touchscreen after heavy gaming or when exposed to sunlight. The replacement unit is almost flawless, except for one glaring flaw...the white balance on the screen is WAY off! Whites are tinted beige, and the screen looks extremely washed out and warm compared to my first one. Here's a side by side picture (not the best photo, difference is more pronounced to the naked eye).

I'm tempted to send this one back, but I don't have the time to get stuck in a RMA loop, especially as I'll be travelling this month. What do you guys reckon-should I just keep this device with it's flawed WB, return for a replacement and hope for the best, or return for a refund?
Alternatively, is there any way I can dial out some of the warmness using software? I know there is a color tuning/calibration utility that is included with CM for my Galaxy S-anything similar exist for the N7?

I had the same issue as welll. My recent replacement has better whites bit the screen is still displaying a pinkish tint. My old nexus 7 had a yellowish tint as well. I wonder what the screen temperature is actually supposed to be :\

To the OP you are correct I've started two threads already about the color correction slash grey scale issues. Most agree that Google will not be doing anything about it. Just plain luck or bad luck. Both of those are not bad mine is just in between I would say.
I have linked to this video before http://www.youtube.com/watch?v=MD8n7xaPBMo the way cool blue tint on the unit shown would be grounds for return IMO. Whites need to be white, not yellow warm or cool blue. Just try and do a side by side with an iPad 3 if you can live with the offness then do so, its a lottery at this point.
I started two threads because so many people have said this is an issues, but it varies so much and is so subjective that its doubtful Google will do anything. I prefer the one to the right just because a little cool blue is way better than warm yellow but the New one on the left looks more accurate.
Hows the Backlight bleed?
A good simple test is I go to T-Mobile.com or Engadget their Magenta Pink and Engadget's sky blue are hard to get right. But then again that opens up a new can of worms about your color Gamut and Hue which I am sure also vary device to device. Its obvious by now this is a QC step Google did not require ASUS to perform. Most likely to improve production yields.

Thanks for the informative reply. It's really unfortunate that Asus has dropped the ball so badly with consistency-I can understand lowering some standards for a $200 device to increase production yields, but they've seemingly neglected numerous aspects as evidenced by all the problems the community is having.
As for the new vs old one, the photo is not the best representation-the old device has perfect whites, completely neutral-no tinge of blue at all. Colors gamut is also pretty accurate on the old one. The new one is visibly worse-not only is the white balance off (whites appear beige), but colors are over-saturated and blown out-I noticed a loss of detail immediately just by looking at my wallpaper. Flesh tones are especially bad-much more red than they should be. I even had my roommate do a blind test between the new and old, and he immediately noted that the old device had a "sharper, crisper" screen.
As far as backlight bleed, it's not too bad on both Nexus's (Nexii?). The new one has a bit of bleed in the lower left corner, but it isn't very noticeable and is the least of my concerns at this point. I'm just not sure if it's worth entering the lottery again to see if I can get a better device based on all the horror stories I've been reading here...
Are you aware of any calibration/color tuning utility for the N7? Devs should look into integrating a utility into their ROMs. Something like this:

Sounds like they are messing with what would be called on HDTV's the Sharpness setting.Its gonna take a subpoena to find out what Google and ASUS knew about the color temperature slash calibration or lack their of, and when they knew it. I smell class action down the road. No way its just not right so many units coming out so differently.

Not only color, but I've noticed noticeable differences in brightness between the 3 I've gotten for RMAs. This new one gets darker and brighter than the previous one.

Mine is pretty much spot on, Except for Blue Links tend to be on the purple side of Blue, enough to start a few threads and ask some questions but definitely not warrant a return.
One thing I have its noticed is that its nice bright and vibrant not at all "washed out" as other have reported. But When I go into Display Brightness, (never Auto brightness) when I move the slider I have like 8 or more different levels of Low brightness below the the Halfway Mark so I can really pick to my licking how low I want the brightness, even on the lowest it maybe too bright for reading a book in a dark room.
But above the halfway mark of brightness I only get about 4 or 5 Steps Up to Max brightness, The last inch or more on the slider toward MAx brightness does nothing. So in essence I reach Max brightness well before the slider is maxed out.

That is very strange indeed. My brightness slider doesn't exhibit this-it is linear throughout it's range and the lowest brightness setting is quite dim, perfect for reading at night.

XDA developer Supercurio has an app called screen tuning for the Samsung 10.1 that I loved that changed the white temperature, which I believe is the issue. I think an app like this would help significantly.
Its also been said that the nvidia chip settings causes screen wash out after videos or heavy gaming. Its a battery saving measure while watching video or gaming but persists afterwards when it shouldn't. There's an app around here for that. Nut I'm after a color correction.

The screen tuning app can only be used with AMOLED screens, which the Nexus 7 doesn't have.

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
Screen settings set as standard

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
so i actually bought another one from this dealer i found on kijiji.
The new one was sealed and its from Hong Kong (but assembled in Vietnam)

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)...

mine doesn't have a hue but on really dark colors (like the dark tapatalk theme) the screen color is uneven on the background.

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.

do you know what you are talking about??

amoled is common in that type of tint.. I used all galaxy. Since first galaxy I used.. And now still smiled tech have this tint..
Sent from my Micromax A74 using xda app-developers app

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.

..
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!

Getting a replacement S6 due to screen.

Hello!
So I just wanted to make a brief post and post a pic of my current S6 and why I'm sending it back for a replacement. I noticed today that about 1/4th or 1/5th of my screen (towards the bottom near the home button) is pinkish. It's visible mostly on white images, but now that I've seen it, I can't un-see it! I've read a few other posts here and there about screen discoloration, and I noticed that Erica Griffin touched upon it on one of her videos. I'm thinking that it has to be a hardware problem, cause I can't see how software would cause this issue. Pics below:

Let me know what you guys think. Am I crazy and making things up in my mind, or does the screen actually have like 2 different color calibrations?! :crying:
-Matt

Nope...one of the two I bought look kinda like that. I think yours is worse actually.

I have the same problem but it's towards the left in the middle. But I have to really look for it. It seems to be worse at certain angles. My GF has a Note 4 and her whites look kinda rainbow-ish as well. So maybe it's a Samsung thing?
But like I said in another thread. I've had a 2 M8s, Nexus 5s, and Z3s side by side and none of the screens looked the same. Some looked better, some had different color temps, etc. So if you return it, there's a good possibility the next one won't look as good or have slight defects. I've seen people return phones several times until they were satisfied.

You are not crazy. I had the same problem with the S6 I preordered from tmobile but the pinkish/purplish tint was on the upper 1/3 of my screen. Yours does look worse but mine was pretty noticeable as well. It's actually most apparent on grey backgrounds with the tint section looking much darker than the non tinted part of the screen. And I agree, once you see it, you can't unsee it.
I actually looked for it right away when I got my phone because it's a fairly common problem on super amoled screens. Both the display units I look at at Best Buy had it to some extent, though not nearly as bad. I had it on both the S3 and the S4. I was pretty noticeable on the S4 but I just dealt with it. After how much I paid for the S6, I wasn't about to again.
Anyway, I got my replacement last night and am much happier with the screen. It still suffers from the uneven screen tone issue, but its far less noticeable and something I can definitely live with.

Hrm... how widespread is this issue. I am still on the fence about picking up the S6 and I certainly don't want one if it has uniformity issues. Maybe I'll wait for the second batch to come out before deciding.

I wouldn't worry too much about it. T-Mobile for me is pretty decent about returns. I noticed some scratches on the heart rate monitor glass and they're shipping one out (about a week delay). Seriously, take the chance it's worth it. This phone is amaze-balls.

Well what do you expect? The device isn't even officially launched yet, what people are getting are some pre-released units. Not to mention that the phone has almost no problems, except the flash and now the dead pixels, but the latter one is something which can happen to everybody. Nobody is immune to dead pixels....

I've never owned a Samsung smartphone before, but kept reading how amazing their displays are VS iphone and LG, but there are so many threads like this one.. Don't know what to think. I hope the one I get is fine.

This has nothing to do with preleased units. I got a retail unit that I preordered early. It's probably from the same batch that will be sent to T-Mobile stores on launch day.
This screen issue is something that affects just about all super amoled screens. I've checked out numbers galaxy phones (S4s, S5s, Notes, S6s, etc...) at verizon AT&T, best buy and nearly all suffered from this uneven screen color balance to some degree.
The thing is, in most situations the screen looked absolutely gorgeous. You really can only tell on certain backgrounds (mostly white and various shades of grey). That's why when you go to see the phone at a store with its demo on or casually play with it, you probably won't notice it. But once you get it home and have had a chance to really do things like reading a book against a white background, you'll eventually notice it. As as I've said before, once you see it, you'll always see it.
What matters is how much it'll bother you. My wife and brother-in-law didn't think it was a big deal and would not have exchanged it. My sister and few of my coworkers said they would get a replacement. I got a replacement and am happier for it.

The screen is amazing. Unless you get an S6 with this screen issue that is as severe as the OPs, you display will look fantasticmost of the time. Like you, I came from a LG G2 and also own a Tab Pro 8.4, which both use LCD panels. Even though my replacement S6 still suffers from this issue a bit, I think it look much better than either of those other devices. This is really apparent on photos and videos. I did a side by side comparison of the newest 1080p Avengers trailer from youtube with the S6 and G2 and the S6 looked much better. I simply love the deep blacks and more vivid colors.

My bad, those aren't dead pixels. Those are likely just pieces of lint or dust cause I took the pic with the S6 on my bed. My replacement unit is set to arrive today, so I'm going to take a side by side pic of both phones on a white screen again to compare the difference. Will post it up when I get it :good:.

scratches, dead pixels, and discoloration are all on my check list for when i receive my handset

I wouldn't worry too much about it. T-Mobile for me is pretty decent about returns. I noticed some scratches on the heart rate monitor glass and they're shipping one out (about a week delay). Seriously, take the chance it's worth it. This phone is amaze-balls.

Did Tmobile reship free of charge on shipping and whatever, restocking fees, or any other expenses? Or was the exchange completely free?

Well, second time wasn't a charm lol. Received the replacement unit today and it suffered from the same discoloration on the screen, this time in the upper 1/4th to 1/5th of the screen. I didn't even bother to mess around with it, just packed it right back up and went to UPS and sent it back. At this point, the only option I really have is to wait until the replacement phone is received back at the warehouse, then go into my local Tmobile and get a new device from them in person, THEN send this original phone back via UPS to the warehouse... What a pain in the ass. I'm not sure who to be more upset with, the ridiculous hoops you have to jump through with Tmobile, or the faulty screens/calibration from Samsung.
Edit: The only thing I've found that helps with the problem a little is to switch from basic to AMOLED Cinema under the display settings, but the colors look so ridiculous with this setting that I honestly don't know if I can keep it like this. In fact, I don't think changing it to AMOLED mode actually fixes the problem at all, it just distracts my eyes enough with everything else that I don't notice it as much lol.

Hate to say but I did say it would be 50/50 chance. Quality control on phones nowadays is terrible.

I had to exchange my device 4 times due to a particle inside the glass screen. I didn't notice about the pink hue until I got to my third device and read this thread. I assume that my first two device I exchanged had the same issue.
I too would rather wait for S6 to be release in-store and hopefully one of the reps can notice the faulty display issue. I'm just getting tired of contacting customer service every time to order a new device and return the old one. My EIP is practically piling up.
I just hope that someday the media would pick up on this problem when the device is officially released.

Hehe yea, I figured since it was my first device I'd roll the dice and see if I got lucky; didn't happen haha. At this point, I'm just going to return my original S6 as well, have them activate a microSIM in store and throw it in my old Blackberry Z30 until both phones reach the return destination in Texas. After the refunds and everything I'll pick up another S6, in store this time. (I've learned my lesson: I'm never ordering a phone online again. It's gonna be in store or not at all from now on lol).

Both mine and my gf's Note 4 suffered from this issue. While it was annoying it didn't seem to bad enough to warrant return/exhange. I was concerned about it on my S6 as well. The funny thing is when I first turned it on I didn't notice anything until I switched the screen to the basic mode and turned the bightness down. Whites are definitely uneven, with a warm spot. I don't think its severe enough to replace. But it does seem to be almost unavoidable. I didn't notice it on my S4 until I went back and examined it. Otherwise, the screen is beautiful. It doesn't help being OCD.
The first time I experience this was on a Nokia Icon - it was severe. Fortunately none of my other devices were to that degree.

Yea, I hear ya. See my problem is 2 fold: 1) I am pretty ocd when it comes to defects in things, and 2) I've been using TFT LCD screens on multiple phones for awhile now, and this is my first time back on an AMOLED in a long time. Due to that fact, I'm guessing this issue is sticking out a lot more to me than it might others who have been using AMOLED screens for a couple generations now in succession. I can take a few problems with a phone here and there, like a scratch on the metal or whatnot, but when there's a problem with the screen of a device, you can't get away from it. Every time you use the phone, you have to see it :\.
