Default How to lock the device with sense 6 toolbox very easy!

Hey guys I found how you can lock the phone just pressing the back button!

You must have sense 6 toolbox and enable the "back button to kill an app". If you are on the home screen or in the app drawer just press a hold the back button and the phone locks!
So easy....
