Function:
  Turn off and lock the screen for your beloved phone.
  Because this function already exists on your phone it is the power button (power). But because pressing too much it will quickly become greasy. So we write this application to help users reduce the burden on the power button (Power).

This app uses the Device Administrator permission.
To uninstall Lock Screen app:
1. Go to phone's settings > Security > Device administrators > Uncheck Screen Off and Lock.
2. Go to phone's Settings > Apps > Lock Screen > Tap uninstall.
