Hi folks.
I installed Tap Tap screen unlock on my LG . Unfortunately it works intermittently. Activates only if I try to do it within 30 seconds after the screen goes blank.

This program uses the proximity sensor to ON the screen with a wave of your hand in front of the screen. Could anyone here suggest any tips to make this work. Or are there any other screen unlock program out there. - worried that my Power ON button on the fone will soon become faulty due to being pressed often to ON the screen. Thanks .
