Button Mapper: Remap your keys

Button Mapper is your go-to app for customizing the functionality of your device's hardware buttons. With this powerful tool, you can easily remap your volume buttons and other physical or capacitive keys to execute a variety of actions, launch apps, or activate shortcuts with a single, double, or long press.

Whether you're looking to remap your volume buttons, assist buttons, or the capacitive home, back, and recent apps keys, Button Mapper offers extensive flexibility. It also supports remapping buttons on gamepads, remotes, and other peripherals, making it a versatile choice for all your devices.

For most actions, rooting your device is not necessary, although some advanced features may require an adb command from a connected PC if your device isn't rooted. Note that Button Mapper won't work when the screen is off unless your device is rooted or you use an adb command.

If you encounter any issues, make sure the Button Mapper accessibility service is enabled and allowed to run in the background. Note that Button Mapper does not work with onscreen buttons or the power button, and the available options depend on your device's hardware.

Button Mapper uses Accessibility services to detect when physical or capacitive buttons are pressed, allowing for custom remapping. It does not monitor your typing or collect any personal information, ensuring your privacy is protected.

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."

With Button Mapper, you can truly tailor your device's hardware buttons to suit your unique needs and preferences, enhancing your overall user experience.
