About Button Mapper: Remap your keys

Button Mapper makes it easy to map custom actions to your volume buttons, Bixby button or other hardware buttons. Remap buttons to launch any app, shortcut or custom action with a single, double press or long press. Root is not required.

Button Mapper can remap most physical or capacitive keys and buttons, such as volume buttons, the Bixby button on Samsung devices, LG Assistant button, and the capacitive home, back and recent apps keys found on devices by Samsung, ASUS, HTC, OnePlus, Xiaomi and others. Button Mapper can also remap buttons on many gamepads and other peripheral devices.

Button Mapper does not work when the screen is off unless your device is rooted or you run a special adb command.

A few examples of remapping you can do with Button Mapper:
-long press to toggle your flashlight

Troubleshooting:

-The options shown in the app depend on the buttons available on your phone. Not all phones have home, back and recents buttons!

This app uses Accessibility services. Accessibility is used to detect when the physical or capacitive buttons are pressed on your device so they can be remapped to custom actions to accommodate your needs. It is not used to see what you type. Button Mapper does not collect or share any of your personal information with third parties

This app uses the Device Administrator permission. (BIND_DEVICE_ADMIN)
This permission is used to lock the screen if the "Turn screen off" action is chosen. If you want to remove this permission, open Button Mapper, click on the menu (three dots in the upper right corner) and select "Uninstall"
