Mainly for the HTC One M9 to fix the issue with the vibration motor and auto rotate not working in the Android 5.1 update.
Works on my rooted device, I've not yet tested it on an unrooted device.
Display off - power saver off (vibration motor works).
Display on - Power saver on (vibration motor doesn't work, but you will see notifications).
