Wave your finger to unlock your mobile

Use "Smart Screen on" to unlock your mobile just by waving your finger/s over the proximity sensor instead of using the power button.

You can set the number of waves before unlock in order to prevent accidental wake-ups.

The article author below says that it  could be useful to save the hardware button from wear and tear, but i think it's also useful if you have one of those hard rubber phone protection cases that do cover the power button making it stiff to press whenever you want to press the power button. With this software, just wave and you are done!
