- This question does not appear to be about user experience within the scope defined in the help center.
When I press the phone up to my ear, it seems that the camera recognizes this and either dims or turns off the screen to not allow interaction at that time. I would presume this is a sensing unit to stop cancelling the call etc.
"Sorry, ear hung up the call again!"
