Button Mapper is an innovative tool designed to enhance your device interaction by allowing you to remap hardware buttons to perform any app, shortcut, or custom action with ease. Whether it's a single press, double tap, or long press, you can customize your volume buttons and other hardware buttons to suit your needs. This application supports remapping of most physical or capacitive keys, including volume buttons, assist buttons, and capacitive home, back, and recent apps keys. Additionally, Button Mapper extends its functionality to buttons on gamepads, remotes, and other peripheral devices.
No root access is required for most actions, making Button Mapper accessible to a wider audience. However, some advanced features may necessitate an adb command from a connected PC if your device isn't rooted. Keep in mind that Button Mapper does not function when the screen is off unless your device is rooted or you've executed an adb command.
With Button Mapper, the possibilities are vast. You can configure your buttons to perform a variety of actions, such as:
- Long press to toggle your flashlight
- Remap your TV remote control
- Press to broadcast custom intents, scripts, or commands
- Long press to open the camera and take a photo
- Double tap to launch your favorite app or shortcut
- Double tap to open your notifications
- Swap your back and recent apps keys (capacitive buttons only!)
- Use your volume buttons to adjust screen brightness
- Long press to toggle "do not disturb" mode
- And much more
The pro version of Button Mapper unlocks additional features, including:
- Simulate keycodes (requires adb command or root)
- Swap volume keys on orientation change
- Default to ring volume on Android Pie or later

If you encounter any issues, ensure that the Button Mapper accessibility service is enabled and allowed to run in the background. Note that Button Mapper does not work with on-screen buttons (such as soft keys or the navigation bar) or the power button. The options available in the app depend on the buttons present on your device, so not all phones will have home, back, and recents buttons.
Button Mapper uses Accessibility services to detect when physical or capacitive buttons are pressed, enabling them to be remapped to custom actions to meet your needs. It does not monitor what you type, and it respects your privacy by not collecting or sharing any personal information.
The app also uses the Device Administrator permission (BIND_DEVICE_ADMIN) to lock the screen if the "Turn screen off" action is selected. To remove this permission, open Button Mapper, click on the menu (three dots in the upper right corner), and select "Uninstall."
