When I answer a call on my Note 20 Ultra, the screen doesn't go black when I put it up to my ear. So while I'm talking, numbers are being hit, apps opened, all kinds of stuff. I have reset the phone and removed the screen protector and case. Resetting the phone will help for a few calls, but the issue always comes back. No 3rd party launcher or anything like that installed. Anyone else have this issue? Any idea on what I can do?
