Button Mapper: Remap your keys

Button Mapper revolutionizes the way you interact with your device by allowing you to remap hardware buttons to launch any app, shortcut, or custom action you desire. With a simple, double press, or long press, you can customize your volume buttons and other hardware buttons to suit your needs effortlessly.

This versatile app supports the remapping of most physical or capacitive keys and buttons, including volume buttons, some assist buttons, and capacitive home, back, and recent apps keys. Button Mapper extends its capabilities to many gamepads, remotes, and other peripheral devices, enhancing your control over your tech ecosystem.

You don't need root access for most actions, but some advanced features may require an adb command from a connected PC if your device isn't rooted. Note that Button Mapper won't function when the screen is off unless your device is rooted or you use an adb command.

Here are just a few examples of what you can achieve with Button Mapper:

• 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 many more possibilities.

The pro version unlocks additional features such as simulating keycodes, swapping volume keys on orientation change, defaulting to ring volume on Pie or later, pocket detection, themes, changing back and recents buttons, and customizing haptic feedback on button press and long press.

You can map a wide range of actions to your buttons or keys, including launching any app or shortcut, disabling the button, broadcasting intents, running scripts, camera shutter, turning the screen off, toggling the flashlight, accessing quick settings, showing notifications, power dialog, taking screenshots, controlling music, adjusting volume or mute, switching to the last app, toggling do not disturb, adjusting brightness, and many more.

Button Mapper supports various buttons such as physical home, back, and recent apps/menu buttons, volume up and down, most camera buttons, many headset buttons, and custom buttons on your phone, headphones, gamepads, TV remote, and other peripheral devices.

Additional customization options include adjusting the long press or double tap duration, delaying initial button press for better double tap operation, and disabling Button Mapper while using specific apps.

For troubleshooting, ensure that Button Mapper's accessibility service is enabled and allowed to run in the background. Remember, Button Mapper does not work with onscreen buttons or the power button, and the options available depend on the buttons on your phone.

Button Mapper uses Accessibility services to detect when physical or capacitive buttons are pressed, allowing them to be remapped to custom actions. It does not collect or share any personal information, ensuring your privacy is respected. The app also uses the Device Administrator permission to lock the screen if the "Turn screen off" action is chosen. To remove this permission, you can open Button Mapper, click on the menu, and select "Uninstall."
