Here's a side-by-side of two ATT GS2s on auto brightness showing the same application. The one on the left has a bluish/greenish tinge to the display, while the one on the right looks...I dunno...pinkish? Almost dirty by comparison, at least to my eyes, as it's much harder to read in low light settings. I thought at first it was the Helvetica vs stock font, but it's clearly the panel's lighting characteristics.

Here are the same phones again running the 'dead pixel test' from the Market, set to max brightness on the white screen color test.
The one on the right doesn't seem to be able to produce a true white.
Now, I get that there are different screen suppliers, and manufacturing variances among panel batches, but this whole thing has me a little disappointed at Samsung's QC. I would love to know what qualifies as a successful screen test, because the one on the right is a huge disappointment to my eyes. Just for the hell of it I compared both screens to my old Captivate, and to my surprise that had the most accurate color reproduction of the three.
How bout you guys - true whites on your screen? (try the gmail app, for example) Maybe I just got a bad batch?
The screen on my SGS2 has no colot tinge whatsoever. It's white and bright. I did however notice a bluish tint on my Infuse; which drove me crazy. I actually exchanged 3 Infuses because of a flaw in market where I got the "unable to download, insufficient memory on device". Each Infuse had a different tint, or brightness to the display. I switched to thw SGS2 and haven't looked back since.

Wow... big difference.... what the hell...
I thought this too about my SGSII when comparing it side-by-side with store units... Turned out for me the brightness was the same but another setting (adjust screen to save battery or something like that) was checked on my phone, making the screen look like crap on some colors, including making white look gray and yellow look bluish. Once I uchecked that box the display looked fine.
yeah I am anal about colors too. Being a photographer.
So I was looking for ways to improve the displays on my SGS2(now returned).
I have a Gretag i1-Pro spectrophotometer that I use for calibration and also matching color swatches. So I 'calibrated' my screen to the best of the available software. There is a program call 'Screen Adjuster' you guys can use to alter the RGB values. However gama will be off, and you can only calibrate EITHER high bias RGB or low bias RGB. There is no way to calibrate both.
Have you tried Supercurio screen tune? He just started making it but can probably help you out with colors and such.

QC and screen temperature were both big issues with the ISGS2 when it launched. There's a 100 page thread that's been talking about it since May. Five ISGS2's side-by-side all had from slight to wild differences in color temperature. Some of the ROMs also alter color temperature which makes it even more confusing. Cool/blue is what's intended to be normal and warm/yellow is the exception. The phone on the right in the pic looks like it has a warmer screen. I'd guess they changed either the screen or manufacturing process for the ASGS2 or you guys would have been freaking out by now.
P.S. - Samsung manufactures all their own displays and they all come from the same factories. So if there are differences it's QC or allowable deviation.

I can't see the banding all the time but when I do it's very annoying. I'm going to try and post some pics today. Is it normal or can I get it fixed?
No one at all has this problem or has heard of it?
what do you mean by banding? describe it properly
in my case specifically i can see faint gray horizontal lines going across the lcd on my phone about every quarter inch. it is especially noticeable on a white screen. i emailed the ebay seller and they stated that it was normal and i would not be able to return or exchange the phone since it was sold as new. i emailed LG about it and they said it would cost anywhere from $40-$100 if it was actually a flaw. like i said in the first post, i'm going to try and get some pictures up soon (hopefully in a couple hours after i get some sleep) to graphically show what i'm talking about.
DarkKnight62, if it helps in any way: I have observed this on my screen too. The faint gray lines made me believe text lines were burned in the LCD screen, but that would have been pretty much impossible, since I don't read that much on my phone. I can only see this effect when I use the screen as a flashlight - white background and 100% luminosity and it doesn't bother me at all.

even I read a lot on my phone but I keep the brightness lower than the lowest default. so I dont have this problem.
I think, It's due to surface dithering. See our phone is not 16m colors its 256k so the colors that are missing are to calculated and displayed and that's why the horizontal band if the we set no surface dithering (custom roms mik) the banding just vanishes but the quality of display is reduced. All the linear gradient colors are no more gradient.

I do have this gray lines horizontally and vertically if you see the phone far and carefully only in white background... when its near, the lines just dissapears to my eyes, (like if they get used to the display)
"gray horizontal lines going across the lcd on my phone about every quarter inch"
I don't think he is talking abouth the lines between pixels.
can you post a picture so we can understand what are you talking about?
@DarkKnight62 I had a same problem. If you are using francos kernel (and/or roms that have it integrated) it's more visible - very noticeable on wallpapers with smooth gradients. Try switching to stock or mik_os CM7 mod 6.5.4 stable (which is great)...

Hello everyone,
I noticed that at night when I have a black background i can see dark spots that make you notice the color is not uniform.
This defect occurs when all these conditions are verified:
- Completely dark room and eyes accustomed to the darkness for a few minutes
- Completely black screen (like the one in the test screen by typing *#0*#)
- Minimum brightness (but can be seen even at maximum brightness).
In practice, you see lots of little dots of different sizes and shapes, always black as the background, but not the rest of the uniform color (as if they were the signs of glue that is below).
During the day with light are virtually invisible, at night using it would not normally notice, but as soon as the screen remains black for a few seconds (for example when loading a video from youtube), here they are appearing and are really annoying.
I got my phone last week, I would still be time to ask to replace it, but I'm afraid it's a problem of all devices and maybe even put the risk of receiving a worse one (with dead pixels, circles on the screen, etc.).
Someone else has ever noticed these spots? If you have not noticed could you do a test under the conditions that I outlined above?
To understand whether it is a problem of all (in which case I would avoid to let me change) or just mine.
I still have 2 days to apply for replacement, thanks!!
P.S: sorry for my bad english
Same on mine, and a lot of them... not really visible that much only with blank black screen... and sincerely when do you use your phone with nothing on the display ?
Im pretty sure those are manufacturing imperfections in the amoled production process and we cant do anything about it, im pretty sure all phones have it to some extent.
Same here... I think that its bet to just get used to it, that what i did anyway..
Sent from my GT-I9100 using XDA App
Yes, I have the same problem too! Just got the white version of this phone. I also noticed that mine looks like there's a small fingerprint smudge underneath the glass. These don't bother me, but what really bugs me is this faint faded line that runs up and down the screen. It looks like burn-in or something. I can't see it unless I'm playing a certain video with gray backgrounds. Should I swap it out or keep it? The one I have now has no dead pixels, but I'm afraid the new one would...
Hmmm so we all have this problem, any other witness?
Yeah same thing i was thinking im only one
/problem with all oled screens
same with mine..its a flaw by samsung. unequal distribution of glue to stick the glass and capacitive layer
Same here ...
At first I was a bit worried because I also have an LG Optimus SOL E730 with amoled, and it does not suffer from this problem.
So, the only thing that comes to my mind, is that samsung did a crappy job on this phone.
One more thing: When the screen is black, the LG appears as if it's turned off, the Samsung, on the other hand, is a little lit.

So I am seeing some color issues with my SII
Not sure if it's just the way it is (because I am coming from the LG G2x which had the most amazing display you can ever imagine), or is it just my phone.
The funny thing is that even though I am attaching a screnshot, obviously YOU will not be able to see the issue (since of course, the pic itself is fine, and it is the display that makes it wavey...)
I am not even sure I am explaining myself the right way.
Wavy colorts, uneaven, almost cartoonish-like, smeary.
It is most apparent with darker shades
(U can't see it here)

Samsung's Super AMOLED Plus displays exaggerate colors and shades, and that is it's key feature. Not sure about your phone, but if you think something's wrong with your phone, go check with your service provider.

Thank you!!!
Found some info here, i wonder if mine is one of these....

I hope more members will have something to say, perhaps they have experienced this as well.
I was also thinking whether this can (hopefully) be a kernel issue or color calibration issue? I know that some kernels has effect on the colors, but I am out of my field here and completely wrong
The weird thing is that light colors are perfect. When GRAY or BLACK, it just looks bad.

I've got something similar to that.
It's not noticeable in a well lit environment but if I'm in a dark room and have a black screen on my sgs2, some blotches seem darker than the rest of the screen.
I wouldn't be too bothered about this if it was just one or two but there's one large one and a bunch of smaller ones scattered around the screen.
Thanks!
I wish I could upload a photo to show it, but (funny enough), my only camera is my phone's camera (a single student - what r u gonna do?!)
This is especially noticeable when I take a picture or when I use the Music app (pictured above), where there is huge smears of color going from the dark to the lighter.
I hate to even imagine it, but I think I will have to depart from my SII if this is something that isn't fixable. If no one else experience this, I will get a new SII
(i don't know anyone that has the SII so I have no one to compare it to)
Managed to take some pics
Hope U can see it:
Look at the bottom discoloration:
All menus with shades of grey and black present this issue (kernel problem maybe?)
NOTICE POWER WIDGET!!!!
Does anyone else see reddish or pink on their screen? I see it when I tilt the screen. I noticed it a few days ago on my S9+ and now can't unsee it. Straight on it looks OK but at an angle the screen looks pink, like when scrolling through GMail or web page when my phone is on a table at an angle to me. Not sure if I should exchange and risk getting other issues. Otherwise my device has been fine. I went to the AT&T store near me to compare their display models and mine shows some pink compared to the store.

Mine show slight blue tint when tilted
The left one has a slight green tint. No AMOLED is going to be 100% perfect. Actually I think you have one of the better panels. It looks brighter and the white looks thicker compared to the display model.
Based on the number of screwy AMOLED panels I've seen, that one would probably be OK to me. My panel is yellower along the top quarter and I also consider that a keeper you can do so much worse in my opinion. In ten years they may finally nail the technology till then it's lottery.

Mine also turns a little pink if angled... i can't remember if my previous S8 also did so...
Mine turns ever so slightly blue when tilted. It's MUCH better then my Note 8 was, which turned pink at even the slightest angle.
Try factory reset, when I got mine and turned it on I saw from the boot animation that the display was white. When it finished booting it looked like it was stuck with the blue filter on. I factory reset and the display has been normal since
This can be adjusted, at least this is what I did on my S8. Go to settings, Display, Screen mode and fine tune it there.
So my wife and I each have a US T-Mobile model. Her's definitely has the pink screen issue. Duplicating the settings between the phones and the issue persists. I will be contacting T-Mobile for an exchange.
FYI - wound up not being a hardware issue for our phones. I found out that the native Android Night Light setting transfers between phones. Was able to delete,and use Samsung blue light filter settings, using Nova and the instructions here.
https://www.reddit.com/r/GalaxyS9/comments/85blz5/psa_night_light_and_blue_light_filter_overlap/
anyone else experiencing this on their s9+? when i tilt my device, right before the blue shift, i can se a pink/reddish hue go across the display. do you have the same thing? should i be worried? it's kind of annoying, every slight tilt and i can notice it.
I think now that I checked it seems like mine also has a very slight pink touch on it... But i dont really care and I haven't really ever noticed it.
I use black everywhere possible. Dark theme, dark wallpaper, KIWI browser with AMOLED dark turned on, so this way I save my battery, i save my screen, and black is way better on the eye
On many LG devices, there is "kcal" settings to tune the display to eliminate screen burn.
Here's a good example:- https://forum.xda-developers.com/t/...ontrast-and-also-get-rid-of-ghosting.3653992/
I cannot find any alternative or anything similar on the S8 or S9 forums which is strange considering burn in is a big issue on our devices too.
My question is, why is there no similar cure, what am I missing?, Or have I not being look hard enough?
TIA

The OLED pixels are failing. The calibration and color accuracy as well. Since blue pixels die first any compensation be limited and you would lose color/gamma calibration. The blue pixel output is already near its max when new compared to the other pixel colors.
Red pixels generally have the longest lifespan. No way you can accurately color calibrate one of these display by eye.
Once an OLED display is degraded only a new display will really fix it.
The only thing you can do is reduce the wear by not using in direct sunlight. Use manual brightness control and keep below 50%. Use max brightness for seconds not minutes. Use dark mode and get rid of the notification icons at the top. Use dark wallpaper and red or darker icon packs. This N10+ has over 8k hours on it. No detectable display damage or degradation.
Limit exposure to sunlight and excessive temperatures including during storage.
A hot running phone is burning both the battery and display. Correct the cause of excessive power consumption.
OLEDs are very susceptible to water damage; keep water away from phones even if ip68 rated.
My N10+ AMOLED conservation management strategy. So far it remains in excellent condition even though it's been heavily used daily almost every day for 3 years. I slightly rotate the static homepage icons every month or so. Newer Samsung's incorporate pixel shifting as well.
