Volume Button Trick

Remapping custom actions to your volume buttons and other hardware buttons is simple using Button Mapper. A single, double, or long press of a button can be used to start any app, shortcut, or custom action that has been remapped.

Most physical or capacitive keys and buttons, including capacitive home, back, and recent apps keys, as well as several assist buttons, can be remapped using Button Mapper. Several gamepads, remote controls, and other peripheral devices can have their buttons on Button Mapper remapped.

Most operations can be performed without root, however some need for an adb command from a connected PC if the device is not rooted. Except in cases where your device is rooted or you issue an adb command, Button Mapper does not function when the screen is off.
