Used Samsung Galaxy S9+ more than 2 years or use = Zero Burn-in. ROG 2, 6 months is starting to burn. Same use, brightness medium (adaptive), without gaming too much, more web navigation.
Tip: Use classic theme, default theme leave navigation bar aways black (the rest of screen white) and statusbar icons always white causing Burn-in.B But using Samsung black theme on S9+ more than 2 years didn't have any Burn-in.
