ios14 glitch
With ios14 installed on 11 pro max. If you are looking at or typing a text message, and someone calls you, a new smaller banner drops down from the top of the screen. When you answer the call, and put the phone to your face, the proximity sensor does not work and the phone stays lit. This causes your cheek to activate what ever is on the screen. If you make the call full screen the proximity sensor works normally.
