i have this problem(maybe common in amoled devices) if i take gray pitchure and put it on background there is distorsion in grey. like brighter and darker stripes(but you need to look it realy good) for exsample download program screen helper lite and tell me do you see stripes on main gray program screen.
There is a thread going for so long,

I think that he meant this:

I dont think he is refering to both yellowish screens or banding.
I'm having this issue too. It doesnt show itself unless the screen brightness is turned down, and especially an grey background. There will be faint large vertical stripes. It is as if the backlighting is uneven. Increase the brightness and it'll go away.
Seeing that i do not have the yellowish screen problem, no stuck/dead pixels and no bluish tint problem, im very reluctant to send this phone back for a replacement due to this problem. Its something that i can live with.

thank you very much.
please try in LCD Test(*#0*# in Diagnostic Mode) select RED you will see a white border but on my device left-border is green (other sides are OK).
It's very hard to be absolutely sure on red, but on blue and green the edges are definitely all white.

I loaded your JPG onto my Focus and the left side is green. The left side is always green, but the right side and even the top and bottom can also appear green if you hold the phone at certain angles. The green can also appear purple at extreme angles.
Is this a manufacturing flaw, or just a characteristic of AMOLED screens? Could it be some sort of back-lighting source that's located along the left edge that's causing the green tint?
I loaded the picture after downloading it and then attaching it to an email.
It does have a strange tint on the left side.
I then created my own version of the image. I started with a 480 x 800 blank image in Photoshop. I filled the entire image with black at 100% opaque.
Then I stroked the outer edge with 1 pixel of white. I repeated this using 2 pixels and then 3 pixels. As you can see, it is still visible at 3 pixels, but it is starting to turn white. I think we are seeing a consistent result that means the AMOLED screens have a slight design problem that is not considered to be worth holding back this technology from the market. I know I like the display and this is minor.
So I've noticed a very slight, but annoying issue on my Fire. When I'm reading with a black background and white text, I find the whites on the left side of the screen is bright white, then gradually fades to a duller white towards the right side. I flipped the screen to make sure I wasn't crazy, and then the whites were on the right side.
Is this a manufacturing defect, or an issue they all have? Granted, it's subtle, but still is starting to distract me when I'm reading at night and don't want the bright white background.
As an alternative, is there a way to adjust colors in the native reading app (besides the three preset)? I've sideloaded Aldiko, but the right sides of text cut off.
Hi 2 All,
I have galaxy s4 installed offical 4.4.2, when i open setting or task manager in very dark place, i saw abnormal brightness in background.
i thinks it should be black as it is amoled.
is it normal or serious?
is it sign of screen burn?

Open a completely black image. Download a solid black JPG from google as your test. Do the same thing with a completely white image.
Look at those images in full screen mode.
If there is burn in (which CAN happen on an LED screen, though it's actually pixel fading rather than burn in) you should be able to notice it with this test.
If you see fading in the white image, or general non-uniformity in the brightness, it's a sign of fading. (burn in)
If you see a ghost image in the black image, then something is wrong. It means the screen is lighting up when it shouldn't be.
You should not be able to see a residual image on a black screen like you used to with an old CRT computer monitor. The burn is doesn't work that way. What happens is the pixels lose some of their brightness over time. It's subtle, and if the screen is fading uniformly you probably won't notice. But when 1 spot isn't fading, you notice it quickly. This is most commonly seen with the status bar. If it's always black and the area right beneath it is always colored, then the black status bar wont' fade and the rest of the screen will.

Thanks Sir,
actually it was lcd problem
i notice that my display is not uniform ... first i notice when i pull down my notification bar. But seems to be on dark grey or dark pink as well. I can see clearly when is not much light in room. Is just mine or is a common problem? Sry for bad quality pics.
even worse
Hi,
same with my S5. You can see the non uniformity best when the background is grey and the brightness low:
Can someone post a picture of his S5 at the lowest brightness with grey background to show how it should look with a uniform screen?
I just brought a yotaphone 2 and notice the screen (color side) will change to red/purple in color (especially the dark color area , like the black one) when i set the brightness to a low level(below 30%)
is it normal issue to all amoled display??
this is my 1st time to use amoled phone
nope, it could be damaged during transport. check if yellow spots appear, that's usually the sign of damage. nothing to worry about, it's just annoying
It is normal - if you are in dark and you lower brightness less than 20% it gets purple.
