Is this AMOLED screen damaged? When i display a black screen on my phone, it is still brighter than when i turn it to sleep, is that how AMOLEDs normally behave (trying to "shine" the black darkness)?
When viewing the totally black screen (sadly dark gray screen) in dark, i see real black lines and dots on my display, see the picture i painted in mspaint. Is that a damaged screen? They dont show on turned-off display.
I think some old tamagotchi did this too :)

I read AMOLED can shut down pixels when displaying black (and save energy), can they do it after all, when they display gray anyway? Or is it the dimming that saves battery?


My phone is (should hopefuly be) Samsung Galaxy S III LTE (GT-I9305) so it should have AMOLED.

EDIT Ad. 2.: I googled a bit and it seems a common problem for all AMOLED screens. But since it is so hardly noticeable it isnt nothing to worry about. One poster summarizes it nicely here: http://forums.androidcentral.com/samsung-galaxy-s3/260791-amoled-black-dots-dark.html#post2726685
The screen is definitely damaged. The only solution is to replace it.
