Button Mapper: Remap your keys

What Button Mapper does

Button Mapper: Remap your keys changes what selected hardware buttons do when you press them. It suits people who want quicker access to an app, shortcut, system control, or device function without reaching through menus. Supported inputs include volume buttons, some home, back, and recent-app keys, camera and headset buttons, plus many buttons on gamepads, remotes, and other peripherals.

Actions and press patterns

A button can be assigned different actions for a single press, double press, or long press. Depending on the device and available access, actions include launching an app or shortcut, opening notifications or Quick Settings, taking a screenshot, toggling the flashlight, controlling music, changing volume or brightness, switching the last app, turning the screen off, and toggling Wi-Fi, Bluetooth, rotation, or Do Not Disturb.

• Use a long press as a camera shutter or flashlight switch.
• Assign a double press to a frequently used app or shortcut.
• Disable a button or change press timing when accidental triggers are a problem.
• Map buttons on compatible headphones, gamepads, TV remotes, and similar hardware.

Access limits to know

Root is not needed for most actions, but some controls require an ADB command from a connected computer or root access. Button remapping may not work while the screen is off unless one of those conditions is met. More advanced options include custom keycodes, scripts, broadcast intents, and root commands; availability also depends on the Android device and button being mapped.
