Assign custom actions to single presses, double taps and long presses of your phone's hardware buttons. Root is not required.

Button Mapper can remap physical or capacitive keys and buttons, such as volume buttons, the home button on Samsung Galaxy devices, the camera button on Sony devices, and the capacitive home, back and recent apps keys found on many devices by ASUS, HTC, OnePlus, Xiaomi and other manufacturers.

Volume buttons will work with the screen off if your device is rooted. Otherwise, Button Mapper does not work when the screen is off.

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"

This app uses Accessibility Service. This is used to detect when the physical or capacitive buttons are pressed on your device so they can be remapped. It is not used to see what you type. Button Mapper respects your privacy and confidentiality. It does not collect or share any of your personal information.
