Have you ever seen how pressing the power button of your smartphone is? That's how it is for most people. There's really no reason for you to click the power button.

However, if you are tired of the above, you can try this application, which will help you double tap the home screen instead of pressing the power button.

How to use:

Just double tap on the home screen to activate/deactivate the screen, and you are done.

The application doesn't require any access to your data, so there is no way that it can be used maliciously.
