Screen Off (by ewitt)

Turns off and locks the screen. Depending on settings from the first app dialog or immediatelly when app icon is tapped.

On first run user must grant the app the right to do so --> This app uses the Device Administrator permission!

Unlock again by pin or pattern - NOT by fingerprint. (This is a build in restriction of the Android OS after a lock from software.)

Uninstall via Settings -> Apps -> Screen Off -> Uninstall.

(If the app still holds the admin right to turn off the screen, then uninstalling from home screen or app menu, by long-pressing the app icon and selecting uninstall won't work!)
