I just got my Gz One about a month ago and somehow cracked the glass covering of the proximity sensor while at work. Now when I'm in a call the screen and buttons are locked so I can't do anything during a call. I have made the power button end the call so I can at least hang up but everything else is locked. Is there anyway to disable the sensor? I just got this phone special and can't believe the sensor is broke. I really don't want to have to get a new one. Jus looking for suggestions.
