I've had a S20 Ultra since it was released and today T-mobile is changing it under warranty for the 3rd time. Camera stops working,, I do everything Samsung ask to reset , factory rest , app reset nothing ever works or help. I've had Samsung since S2 and this has been the worse experience ever. My kids and wife make fun of me because they all have IPhones I'm the only one with a Android cellphone, I try hard not switching to Apple but after this being my 4th cell I'm close to saying forget it because Samsung knows there's a problems and they are not taking care of there customers. Switching phones is not solving the problem.
