Lock/unlock the screen and turn off the phone using the volume or camera button
Your phone has a power button broken? Using the application Power Button Master, you can lock / unlock the screen and turn off the phone using volume or camera button.
The Power Button Master does not collect or send any personal data.
For the Power Button Master to work, you need to enable the accessibility service and activate the device administrator - two simple steps described on the start screen.
The device can be waked up with volume buttons. To do this, the Power Button Master plays a silent track when the screen is off. This can lead to extra battery consumption. This feature can be disabled for devices that can be waked up using the Home or other button - no extra battery consumption in this case.
The application needs to enable the accessibility service to listen to the volume buttons and activate the device administrator to lock the screen:
1. Touch the first switch on the application screen, find the Power Button Master in the list and turn it on.
2. Return to the application and activate the device administrator Power Button Master in the same way.
You can also select a button to lock the screen: volume down or volume up, or camera button (if available).
Switch on full replacement mode to disable the normal function of the button.
To uninstall the application, you should return settings 1 and 2: deactivate the device administrator and disable the accessibility service.
