When I remove the phone from my ear the proximity sensor usually fails to wake the screen back up, meaning I have no controls to end the call with. Occasionally swiping my finger over the sensors at the top of the screen wake it up, but mostly it takes several attempts, and presses of the screen lock button.
SO annoying when you are leaving someone a voicemail and it's still recording, all they hear at the end of the message is the muffled swipe of a finger and me muttering and swearing at the phone as it carries on recording for another 30 seconds or so!!
Anyone else have this issue??
