Quickly switch my phone between locked and unlocked without going through the menus? I want to be able to quickly disable and enable Screen Lock, without having to manually go through Settings -&gt; Security -&gt; Screen Lock every time. 

Is there a way to create a button on your home screen where, when you press it, it switches the screen lock from "Swipe" to "Pattern"?
You can download macrodroid from the play store. I looked through it and you can use this to disable/enable the screenlock with a shortcut on the home screen. It is simple to use and you can probably figure it out yourself.
