Button Mapper makes it easy to map custom actions to your volume buttons, Bixby button or other hardware buttons. Remap buttons to launch any app, shortcut or custom action with a single, double press or long press. Root is not required.
Button Mapper can remap most physical or capacitive keys and buttons, such as volume buttons, the Bixby button on Samsung Galaxy devices, and the capacitive home, back and recent apps keys found on devices by Samsung, ASUS, HTC, OnePlus, Xiaomi and others. Button Mapper can also remap buttons on many gamepads and other peripheral devices.
Button Mapper does not work when the screen is off unless your device is rooted or you run a special adb command.
A few examples of remapping you can do with Button Mapper:
-long press to toggle your flashlight
