When I'm on a white screen, even when you take a photo with white in the background, you can see faded LNMTL in the background. I think the cause of the problem is screen-burn in.This happens a lot to AMOLED panels when they display the same image for a long time, the pixels got damaged. I don't think there's any way to deal with this other than replacing the screen. This happened because the LNMTL on the top left corner really doesn't move. Nevermind the screenshots I forgot you can't screenshot something burned on your screen haha
No that isn't what is going on. The pixels are not damaged per say. Let me break it down for you. Most AMOLED screens consist of RGB pixels, white consists of combination of all 3 colors. What is going on is not so much that they are burning in but the opposite. It does not matter how long something remained on the screen, what matters is what colors were used up. The cause of your "burn-in" is that when pixels were used, you lost brightness on those pixels. When the pixels lose brightness, it gives the effect of burning. If you make an opposite image and use up the surrounding pixels, it will return to normal. (albeit not as bright, but you won't notice it) Normal LCD has similar issues, except they use 1 or a few lightsources so you don't notice it. In AMOLED each one is its own lightsource so you notice it easily. Overall though the biggest issue is the color blue which has the lowest lifespan. (It also eats up the most battery life out of the 3 colors) (White uses up the most out of all colors, followed by purple(red+blue) and followed by yellow(green+blue) ) If you want the best battery life with least usage of pixels stick to as much black(uses no power at all and infinite life) and green(longest life) as possible followed by red(least battery). As for your issue, get FireFox Mobile and use Reader Mode. (If your phone has a reader display setting, use that too as it reduces blue usage)
I don't think you'll need to buy a new one. A friend of mine had the same problem on his TV and just "burned it away" (as he called it) by having one colors filling the entire screen and switching to another every few seconds. Took a few days, but the problem was gone.
Any static image will do that. It will fade away anyway. Minimum brightness all the way is the solution.
Oh, I thought this only happens with plasma screens. So it can happen to amoled too. Good to know. Ai-chan already knows to avoid lnmtl though. Ahaha.
Take a screenshot, invert the colors and display it for a while. It will return to normal. (after the brightness evens out)
