F2L

Lock your phone by closing the flap. No need to press the lock button anymore.
If you do not have a flap cover, then merely putting the mobile into your pocket
will lock the screen. Also you can specify to disable the app while a call is in
progress. Time can be set for which the app will remain disabled once you unlock
the screen. This avoids unwanted locking. By switching off the screen you save
the battery, too.
