Key Mapper · Description
New trigger! 🎉 Remap your Assistant & Bixby, and DPAD buttons!
What can be remapped?
* Volume buttons.
* Power button via Google Assistant, Pixel Active Edge, Double press Bixby button.
* Bluetooth/wired keyboards.
* Fingerprint gestures on supported devices.
* DPAD buttons on game controllers.
* Buttons on other connected devices should also work.
You can combine multiple keys from a specific device or any device to form a "trigger". Each trigger can have multiple actions. The keys can be set to be pressed at the same time or one after another in a sequence. Keys can be remapped when they are short pressed, long pressed or double pressed. A keymap can have a set of "constraints" so it only has an effect in certain situations.
What can’t be remapped?
* Mouse buttons
* Thumb sticks or triggers on game controllers
Your key maps do not work if the screen is OFF. This is a limitation in Android. There is nothing the dev can do.
What can I remap my keys to do?
Some actions will only work on rooted devices and specific Android versions.
There are too many features to list here so check out the full list here: https://docs.keymapper.club/user-guide/actions
Permissions
You don't have to grant all the permissions for the app to work. The app will tell you if a permission needs to be granted for a feature to work.
* Accessibility Service: Basic requirement for remapping to work. It is needed so the app can listen to and block key events.
* Device Admin: To turn the screen off when using the action to turn off the screen.
* Modify System Settings: To change the brightness and rotation settings.
* Camera: To control the flashlight.
On some devices, enabling the accessibility service will disable "enhanced data encryption".
