Hi
Just wondered if the Screen Adjuster app poses any risk of damaging the S4 screen after a while? My phone has a noticeable yellowy green tint which makes photos and videos appear slightly green. I downloaded the Screen Adjuster app which lets you adjust the red green and blue sliders and it reduces the yellow tint (although it doesn't work when playing videos annoyingly).
I have seen on other similar apps the developer putting a warning not to use the colour slider tints on OLED screens as it damages them, so I just wondered if I always have the Screen Adjuster switched on whether I am damaging my screen in the long run?

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.
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?

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 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.
So I was just getting used to the green tint on my screen by applying a dark filter to reduce the green effect to suddenly realise it completly disappeared from my screen totally by itself!! I'm just glad I didn't do a screen change yet!!
Screen Change
Has anyone noticed there is a gradient in brightness on the main display of the LG g8x or is it just me and my phone
The best way to notice this is to open any gray background and look at it in landscape mode
yes, Many of them have same problem but it affect only in night time, day time can't find the issue.i don't know whether gradient, uniformity issue are same but my phone have uniformity issue (dark gray background with 0% brightness) bright in top,dark patches in bottom.so I change screen colour to sport and warm temperature better than before screen (reduce only small part of dark patches in bottom ).use dual screen in dark room change the screen colour you may see the difference or may not .uniformity issue also in LG latest oled tv.
