I have had a galaxy A50 since July 2019 and I have had an issue with it for awhile. The screen flickers all the time on its own. It does not allow me to unlock it as it flickers back to the lock screen as I am attempting to enter my pin. When I am doing something on my phone it will snap out of it and going to the lock screen. This issue is very annoying. I have done soft resets, deleted downloaded apps, and done a factory reset. Nothing has helped this. My phone is under warranty, but I don't know how to get a new phone sent to me. Please advise.
