Unable To End Call After 8.1 update

re:

A ton on the forum team have screen protectors on theirs with zero issue....
Please tell me which full screen screen protectors you are all using or can recommend and I'm more than happy to try them, thanks, David.

I've got this issue now, too. It was fine until the 8.1 update. Very frustrating for sure. My screen protector was on the phone since Day 1. Never had a problem until now.
