Button Mapper: Remap your keys

Button Mapper is a versatile tool that simplifies the process of remapping your hardware buttons to execute a wide range of custom actions. With Button Mapper, you can transform your volume buttons and other hardware buttons to launch any app, shortcut, or perform any action with just a single, double, or long press. This powerful app supports remapping for 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 various peripherals like gamepads and remotes.

For most actions, rooting your device is not necessary, though some advanced features may require an ADB command from a connected PC if your device is not rooted. It's important to note that Button Mapper does not function when the screen is off unless your device is rooted or you execute an ADB command.

Here are some practical 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

The app supports a range of buttons including 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 peripherals.

Button Mapper offers additional options such as:

For troubleshooting, 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 or the power button. The available options in the app depend on the buttons present on your device, so not all phones will have the same capabilities.

Button Mapper utilizes Accessibility services to detect when physical or capacitive buttons are pressed on your device, enabling them to be remapped to custom actions to meet your needs. It does not monitor what you type, and your privacy is respected as no personal information is collected or shared. The app also uses the Device Administrator permission to lock the screen if the "Turn screen off" action is selected. To remove this permission, you can open Button Mapper, click on the menu (three dots in the upper right corner), and select "Uninstall."
