Lock Device Widget (com.xbmi.lockdevice) on Google Play
A very simple widget to lock your device with a single touch. Useful for big devices hard to lock one handed or when it's sitting on a table. Also useful when the power button becomes defective! It has multiple widget styles available and a launcher shortcut (like an app icon) is also included.It requires a Device Administrator privilege to lock the screen. **** IT MUST BE DISABLED IN Settings > Security > Device Administrator, or press Deactivate in the Play Store IN ORDER TO UNINSTALL IT!! **** Sorry for the caps :(Button to donate inside the app if you wish to support me :)
