Button Mapper can remap most physical or capacitive keys and buttons, such as volume buttons, some assist buttons, and capacitive home, back and recent apps keys. Button Mapper can also remap buttons on many gamepads, remotes and other peripheral devices.
Root is not required for most actions, however some require an adb command from a connected PC if not rooted. Button Mapper does not work when the screen is off unless your device is rooted or you run an adb command.

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, it is safe and your privacy is respected.
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"
