Call Screen Lock description

Ever hang up your phone right in the middle of a conversation? Not anymore!! Call Screen Lock can help with this. Anytime that you are actively in a call, Call Screen Lock will prevent any touch events on your screen. When the call is over, Call Screen Lock quietly goes away. To access your screen while in a call, just tap the lock key in the upper left of your call screen. The screen will then be unlocked and the key is replaced by a lock icon. Tapping the lock icon will re-engage Call Screen Lock once again.
