Key Mapper

Fingerprint gestures, volume buttons, navigation buttons, and buttons on connected devices can be remapped using this app. However, only hardware buttons can be remapped and there is no guarantee that all buttons will work. This app is not designed for controlling games and the device's OEM/vendor may prevent buttons from being remapped.

Multiple keys from a specific device or any device can be combined to form a "trigger" and each trigger can have multiple actions. These keys can be set to be pressed simultaneously or in a sequence. They can also be remapped for short presses, long presses, or double presses. Additionally, keymaps can have constraints so they only have an effect in certain situations.

However, there are some buttons that cannot be remapped, such as the power button, Bixby button, mouse buttons, and buttons on game controllers. It is also important to note that key maps will not work when the screen is off, as this is a limitation in Android.

The app offers a wide range of actions that can be assigned to remapped keys, but some may only work on rooted devices and specific Android versions. A full list of these actions can be found on the app's website.

When using the app, certain permissions may need to be granted for certain features to work. These include accessibility service, device admin, modify system settings, and camera. However, not all permissions need to be granted for the app to function properly.

It is also worth noting that enabling the accessibility service may disable "enhanced data encryption" on some devices. For more information and support, users can visit the app's Discord or website.
