Unleash the power of your keys with KeyMapper! This open-source app lets you remap various hardware buttons on your Android device.
What can be remapped?
KeyMapper allows remapping of:
- Fingerprint gestures (on compatible devices).
- Volume buttons.
- Navigation buttons.
- Bluetooth and wired keyboard keys.
- Buttons on other connected devices.
Important Note: Only hardware buttons are supported. There's no guarantee all buttons will work, and the app isn't designed for game control. Your device manufacturer may also restrict remapping capabilities.
Creating Custom Key Combinations:
You can create powerful "triggers" by combining multiple keys from different devices. Each trigger can execute multiple actions, with keys pressed simultaneously or sequentially. Customize your remapping for short presses, long presses, or double presses. You can even add "constraints" to limit trigger activation to specific situations.
What can't be remapped?
The following are NOT supported:
- Power button
- Bixby button
- Mouse buttons
- Game controller D-pad, thumbsticks, or triggers
Screen-Off Limitation: Keymaps are inactive when the screen is off—an Android system limitation.
Remapping Actions:
Many actions require root access or specific Android versions. For a comprehensive list of possible actions, visit: https://docs.keymapper.club/user-guide/actions
Permissions:
KeyMapper doesn't require all permissions to function. The app will inform you if a specific permission is needed for a particular feature. Required permissions may include:
- Accessibility Service: Essential for key remapping; allows the app to monitor and intercept key events.
- Device Admin: Enables screen-off actions.
- Modify System Settings: Allows brightness and rotation adjustments.
- Camera: Controls the flashlight.
Heads-up: Enabling the accessibility service might disable "enhanced data encryption" on some devices.
