Angle Unlock Android App

'Unlock your screen with the phone angle.'

This application disables your lock screen only when your phone is placed horizontally.(see the tutorial image)
I think it is very useful when you want to lock the screen in your pocket, and easily unlock it when you pick up the phone.
To say about my usage, I can use my device's default light key from the lock screen when I just make the screen on in a vertical or up side down angle. I don't need any light apps with this app.

On the settings view, you can set the play of phone's angle from horizon so that you can disable the screen in some gaps of angle.
Please note that the angle is computed from the acceleration sensor, so sometimes it cannot disable the lock screen when you shake the phone.

And please note that according to the Android specification, it sometimes occurs that you suddenly see the screen locked since Android destroys my background service when in low memory or other circumstances.

Privacy policies:
As you can see from the permissions opened, this application does not use or send your data at all. I've implemented this application carefully for your phone and mine, but even when this application happens to go incorrect and it harms you, I have no responsibilities about it, sorry.
