Screen Lock

Just one touch to lock and turn off screen, Use me to protect your lock button.

The hardware power button of some devices is not well designed. The frequent use to power on/off screen may damage it. Use the software shortcuts to replace it and extend its lifespan

Note that:

* This app uses the Device Administrator permission.

* Uninstall:you have to go to "Settings—>Security—>Device administrators" to shut off "Screen Lock" first.
