This app requires device administrator privileges to implement the "lock screen" launch action. This app uses the accessibility service for some startup actions only if needed. Total boot is the best customizable launcher in android. Of course, it's still fast, lightweight, and easy to use. I'd just like to tell you one sentence. "Hold to Edit" You can customize it, whatever it is.
