Button Mapper: Remap your keys

Reassign hardware buttons to trigger any app, shortcut, or action

Button Mapper simplifies reassigning custom actions to your volume buttons and other hardware keys. Customize buttons to open any app, shortcut, or action with single, double, or long presses.

Button Mapper supports remapping most physical or capacitive keys, including volume buttons, select assist buttons, and capacitive home, back, and recent apps keys. It also works with many gamepads, remotes, and peripheral devices.

Root access is not needed for most actions, though some require an adb command from a connected PC if not rooted. Button Mapper is inactive when the screen is off unless the device is rooted or an adb command is used.

A few examples of what Button Mapper can do:

-Long press to activate your flashlight

-Reassign your TV remote control

-Press to send custom intents, scripts, or commands

-Long press to launch the camera and snap a photo

-Double tap to open your favorite app or shortcut

-Double tap to view notifications

-Swap back and recent apps keys (capacitive buttons only!)

-Use volume buttons to adjust screen brightness

-Long press to enable "do not disturb" mode

-And many more options

This app uses Accessibility services to detect physical or capacitive button presses for remapping to custom actions, tailored to your needs. It does not monitor your typing. Button Mapper collects no personal data, ensuring your privacy is protected.

This app uses the Device Administrator permission (BIND_DEVICE_ADMIN)

This permission enables screen locking if the "Turn screen off" action is selected. To remove this permission, open Button Mapper, tap the menu (three dots in the top right), and choose "Uninstall"
