It's that simple! Right after installation everything is set up and ready to go - the next time you call someone, all you have to do is press the back button and the phone will hang up.
Anyway, have in mind that if you press Android back key when the screen is off, nothing will happen, and this is expected behavior as, for instance, you could hit the back key by accident when phone is close to your face.
The back button will end call only when you are on call screen, because you should be able to use back button to navigate back from any other screen.
Some other great features inside:
✓ Setting to lock the screen when you end call, even if you hang up without this app.
✓ Vibrate phone when you end call with back key (great for accessibility).
✓ Silent mode - no reminders are shown in Android status bar or any other notifications (only available in Pro version).
Have in mind that this app is extremely lightweight:
✓ The service is started only when a new call is initiated and is stopped always when the call ends.
✓ Small in size.
✓ Really fast
Now the greatest missing feature in Android is finally here!
