I am getting the same issue in my S20+ from 7th AUG after updating the software. I neither dropped my phone nor dropped in liquid and is in case at all times. At first the screen turned to white lines and came back but now the issue persists and is no longer usable because of the display issue.
I first faced this issue 2 months back and it went away on its own after a while. I was assuming that the software updates (I always keep my phone updated) must have fixed the issue. This morning the issue has come back to haunt me and I really don't know what to do. Can samsung please find a solution to this problem? Tried disabling adaptive brightness, always on display , changed screen resolution but nothing seems to be working. Attached is the video of the issue and the software information of my phone. Samsung, many loyal fans are desperately looking for a solution. Please help.
I am currently facing the same issue with my Samsung galaxy S20+. The phone was bought on March 2020 and has past the warranty period. The flickering starts from Saturday (7 Aug) morning, no apps were running at that moment and did not drop the phone or so, it just occur suddenly. Tried to update the software to latest and restarted the phone in safe mode but the same issue still persist. The only way to read the screen currently is connecting the phone to PC using Samsung Dex. Contacted online Samsung customer service, they only suggest to reset the phone in setting first then only restart in safe mode (but obviously not helpful as I can’t even read the screen) or attend to their service centre for inspection and repair (with charges of course since warranty period has past). Since many S20 users are affected there is obviously something fishy about the quality of the device. Very disappointed in Samsung, perhaps is time to consider other brand.
