Hey,
Today, I was looking at Screen Lock button of my android mobile. Since i use this key frequently, It almost turned in to white colour from Silver. So i just searched in Play store and found an interesting Widget.
Its “Screen Off” – One click to turn off screen and lock device without touching power button. After installing “Screen Off“, you can find it in the “Widget” to add it to desktop.
Installation
Play Store Download Link
– Install it >> Grant Admin privilege when it asks >> then add the Widget to your Desktop.
– Now Simply click the widget to lock your Phone.

Un-Installation
You need an Extra step to uninstall this widget.
– Go to Settings>> location & Security Settings >> Select Device Administrators.
– Uncheck the “ScreenOff” application from the list and click Deactivate.
– Now as usual, Uninstall the application from Settings >> Applications.
