Button Mapper: Remap your keys

Button Mapper is the ultimate tool for customizing your device's hardware buttons to suit your needs. With this powerful app, you can easily remap your volume buttons and other hardware buttons to launch any app, shortcut, or custom action with just a single press, double press, or long press. Whether you're looking to enhance your device's functionality or simply make it more convenient to use, Button Mapper has you covered.

Button Mapper supports remapping for a wide range of physical and capacitive keys and buttons, including volume buttons, certain assist buttons, and capacitive home, back, and recent apps keys. It's not limited to your phone either; you can remap buttons on many gamepads, remotes, and other peripheral devices. While root access is not required for most actions, some advanced features may necessitate an adb command from a connected PC if your device is not rooted. Note that Button Mapper does not work when the screen is off unless your device is rooted or you run an adb command.

With Button Mapper, the possibilities are nearly endless. Here are a few examples of what you can do:

• 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 even more features, including:

• Simulate keycodes (requires adb command or root)
• Swap volume keys on orientation change
• Default to ring volume on Android Pie or later
• Pocket detection
• Themes
• Change back and recents buttons
• Customization of haptic feedback (vibration) on button press and long press

You can map a variety of actions to your buttons or keys, such as:

• Launch any app or shortcut
• Disable the button
• Broadcast intents (PRO)
• Run scripts (PRO)
• Camera shutter
• Turn screen off
• Toggle flashlight

Button Mapper supports a variety of buttons, including:

• Physical home, back, and recent apps/menu buttons
• Volume up
• Volume down
• Most camera buttons
• Many headset buttons
• Custom buttons: add other buttons (active, mute, etc.) on your phone, headphones, gamepads, TV remote, and other peripheral devices

Additional options allow you to:

• Change the long press or double tap duration
• Delay initial button press for better double tap operation
• Disable Button Mapper while using specific apps
• Plus many more customizations

If you encounter any issues, ensure that the Button Mapper accessibility service is enabled and allowed to run in the background. Remember, Button Mapper does not work with onscreen buttons (such as soft keys or the navigation bar) or the power button. The options shown in the app depend on the buttons available on your phone, 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 on your device, allowing them to be remapped to custom actions. Rest assured, it does not collect or share any of your personal information, ensuring your privacy and safety.

Additionally, Button Mapper uses the Device Administrator permission (BIND_DEVICE_ADMIN) to lock the screen if the "Turn screen off" action is selected. If you wish to remove this permission, you can do so by opening Button Mapper, clicking on the menu (three dots in the upper right corner), and selecting "Uninstall."
