I blame the screen protector on that... the way i see it, you have a couple options:
1. remove the hard screen protector from the case, and put one directly onto your phone so that it's still protected
2. Call/email otterbox and tell them that their case is limiting you from using your device, and see if they can send you a commuter case.
