The left side of my note 20 ultra 5G flashes white. I've tried resetting the phone. Hard reset. The only other option is a full factory reset. I have not dropped it. No water damage either. It will go back to normal for a few seconds occasionally.
Hello there, I would recommend testing the device in safe mode to see if you still get the white flashes. If the screen still flashes white in safe mode I would recommend having your device evaluated by a certified technician, you may have a couple of options for this depending on your location. You can either contact your local uBreakiFix location to see what options they have available at the moment for evaluations or I'd be more than happy to get you set up with a service ticket to have your device shipped to the Samsung service center so that in house techs can evaluate and diagnose your device.
If you would like to ship your device in please send me or any of the other moderators in the Community a private message with the full model code and IMEI number of your device.
