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.

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 !

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.
I did a search and haven't really seen anyone else report this.
My display seems dimmer around the edges. Does anyone else have this? It's not like a light bleed issue either.
Don't use the home screen to judge that if you are. Mine definitely dims by itself on the edges. Use the display tester app and see if you're getting the same results. I think I notice a very slight difference along the edge of the screen compared to dead center, but it's not enough to notice during normal use.

Hi everyone.
I have not seen this mentioned in N4 forum, hence I decided to start a new thread.
After my much awaited N4 sitting at the local UPS depot for 3 days, I have finally received it.
I did anxiously unpack and start it as soon as I got home. To my surprise, I’ve noticed significant amount of ghosting, particularly evident when swiping a screen with clock widget on dark background. I did come in from the cold, and knowing how laggy displays are when cold, waited a few hours to try again. To my disappointment the ghosting effect was still there. It can be clearly seen when compared side by side against Galaxy Nexus performing the same task.
I’ve never heard of ghosting being a software defect. So presumably the fact my device is still at 4.2 (as opposed to 4.2.1) does not have anything to do with it.
Did anyone experience anything similar? Does it go away with display use?
Thank you,

Thank you. Perhaps I have a defective unit. As I previously mentioned it seems to be substantial in comparison to the Galaxy Nexus SuperAMOLED HD. I realize this is not a TV screen. However I am a bit disappointed it is a step backwards in terms of display.
I read plenty than some people did not like the colors. I am perfectly fine with N4's color saturation. It is the ghosting trailing effect when scrolling up/down in settings menu that drives me nuts.
Chris Chavez from phandroid thought the same thing ...I think its a defective unit or you just have "special eyes"

I'm not sure if I'm the only one, but when I browse Reddit Sync on AMOLED mode on a decent brightness, I get minor to severe ghosting on certain images. Its gets worse on lower brightnesses, and I'm not sure if this is common occurrence for AMOLED screens, or if I'm the only one. Thanks in advance.
Link a page you're getting ghosting on so we can test it, also tell us what brightness setting.
I get screen ghosting when the color changes from pure black to grey. Especially when scrolling a black object on a grey background, I can observe the back pixel takes some time to switch to grey.

I get it as well, I think it's just a limitation of AMOLED panels. Not sure if the newest (on the Galaxy S7) have it as well but it happens with a lot of AMOLED panels.
Hello guys, suddenly I'm having display issues on my k20. I've attached a link to the video, when i pull down the notification bar, look how the blacks are loading a bit late. When i turn off dark mode, i see no issues like this, it's just the beautiful display again. Even i had same issues with my dark wallpaper. Please check, if you've same issues. I'm really concerned about it. Also, this maybe screen flickering but when i increased brightness, the issue didn't disappear, it was still persistent but at lower levels.

That's normal behavior for amoled displays.
1st: If this is the display problem, how can you expect we can see this on a screen capture??
2nd (probably because of the 1st): I can't see anything wrong.
3rd: I have no display issues at all.

I can not see anything wrong or violet at all. Am playing this on my computer at 1080 resolution and 0.25 playback speed and there is nothing to see.
If your screen is faulty, we are not able to see it on video you have shared with us of course
DAMN IT! Even i see nothing from my laptop
I think I'm having screen issues, only when its dark mode, else the screen is working absolutely fine!
I need to get to the service center ASAP! :crying:
Edit: Guys can you try doing the same and look if the issue is persistent in your screen too?! It would really be helpful for me.

It's normal for OLED panels, some are better, some worse. My phone has it too. No need to go to the service center.
I too have it brother. Dark mode has it normal mode doesn't. It can also be noticed if you open youtube and scroll back and forth quickly. The blacks seem to be spilling or streching. I saw that on your video and I don't know if it is normal or not but i too have that and wanted to ask someone about that.

People are claiming this to be normal, but after searching a lot i got to know these kind of issues come after 1-2years, not in a week or month. So I'm trying my best to replace my device or get the screen changed. I don't understand why Xiaomi is keeping the colours to pure blacks when they know their displays are facing smearing issues. I hope someone just changes that pure black colour to very dark grey colour, system widely. Some developer tested(on OP7 pro) the battery consumption difference with pure black and dark grey and it turned out that, dark grey consumes only 0.067% more power than dark inky blacks. I'm humbly requesting developers to change the colour, or at least have an option for the same.
My display when there is low light, the brightness is set to low and the image I see on the display is darkish I can see a vertical line at the left side of the display, is this normal or should I return It?
It's normal for Amoled screens (from first day of use). Just search for Amoled black smearing and you'll find a lot of videos and articles. S10 has it, iPhones have it too.

I have faint vertical lines on the right of the display when the brightness is low which is how I normally use it. I also have black smearing on pitch black to dark color transition. I think thats normal, it doesn't really bother me all that much.
The best way to reproduce this issue is turn off brightness to minimum and turn on reading mode to max. Then you'll see delay of displaying some colors (mostly gray)

My k20 has this issue and it's annoying that after paying for a flagship killer, we just got a cheap display which is not just low in quality but has these issue in dark mode which i think most of us use. Interestingly when i record this from screen recorder,it doesn't show up much but the same can be seen visually. So, this is definitely an issue that redmi is trying to let go.

As you "record from screen recorder" you do not record from the screen as you may like to think. You capture the video signal BEFORE it gets to the screen. So any imperfections caused by the amoled screen do not show up on a screen capture.
Anyway, this is a normal weakness with all amoled screens that I have seen.
It is soooo annoying when in dark mode at low brightness, I feel like I couldn't stand it anymore. The worst experience of display usage ever.
Maybe with DC dimming update that might happen someday, the issue won't be as intrusive and pronounce as it is right now. But whenn???
UPDATE:
So I found a workaround for this issue with an app. It's called Screen Balance. Basically it adds a filter overlay on your screen (ineffective on notification panel, because android restriction). Set it to either flourescent or flourescent (warm) at 15% strength minimum, and both brightness and contrast at 100%. You won't see perfect black anymore, but very close to that and no smearing effects visible unless you're really trying to.
I've bought Mi 9T Pro and have the same issue (also see it in your video). Did you fixed that?
