A warning! Don't do the white screen thing! I just saw this!
The white screen thing is what is done for LCD, not AMOLED screens.
"Unlike LCDs, OLED burn-in cannot be 'washed out' by displaying a complete white screen for an hour or two. A white image on an LCD causes the crystals to relax, thereby alliviating the problem of image retention when showing constant items such as desktop icons or status / task bars. But on an OLED screen, a white picture will cause more wear and degredation of the light emitting diodes".
I found this from the Web, just a heads up. Use an app to fix this like I am (and it seems to be improving a little).
The app I am currently using is linked here and it IS improving the issue
https://forums.androidcentral.com/e...ails?id=com.rane.screentestfix&token=pLKJRcZF I'm trying to find information for why this works, so I'll add more when I find the proper information. Apparently most displays only have ghosting, and not actual "burn in". It can go away after a while from what I'm reading (but I can't prove this is 100% true at the moment).
Update: this app works by evenly using all the colors of the pixels, leveling the display colors. I just hope it solves the issue
