Your power button is broken or it is deterioring over time. But you have to user power button to turn on and off your phone. It is a big problem.

AnyUnlock will save your power button. It has two functions:

1. Use any key to turn the device on (by disable the default keylock). It contains a simple lock screen to prevent the mistap. Press "back" key to unlock the phone.

2. Use a home screen widget to turn off the phone.

3. Very small. 40k install size.

4. Do not keep the phone awake and do not consume considerable more battery power.
