Nope in samsung amoled displays there wont be screen burn in issue and that issue will be there with LG OLED display phones. This may be something else. And you need to understand what's screen burning is exactly.
who said samsung amoled screens dont have screen burn? most of the amoled screens end up with screen burn. The very classic example is YouTube white timeline...even that causes screenburn in amoled. search for it and ull find out
2 solution.......it's oleophobic coating issue means cosmetic issue ..so Samsung warrenty will not applicable here ...if you go to service center then they will replace whole display only....a d 2nd you can get so many nano coating material at amazon to coat it again from home....but try to purchase a good one ..
