About this app

What can be remapped?

* Fingerprint gestures on supported devices.
* Volume buttons.
* Navigation buttons.
* Bluetooth/wired keyboards.
* Buttons on other connected devices should also work.

ONLY HARDWARE buttons can be remapped.
There is NO GUARANTEE any of these buttons will work and this app is NOT designed to control games. Your device's OEM/vendor can prevent them from being remapped.

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?
* Power button
* Bixby button
* Mouse buttons
* Dpad, thumb sticks or triggers on game controllers

Your key maps don't 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 keyevents.
* 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".

Ratings and reviews

One of the best remapping tools I've used, and my personal favorite. Shizuku compatible and easily integrated with Tasker via shortcuts and intents. Ordinarily, I'd rate ★★★★☆ for an app like this, because I reserve 5 star ratings for apps which I have no complaints about. Key Mapper gets 5 from me because, despite all the excellent features, it's 100% free. REALLY free. No restrictions or limitations you have to pay to get rid of, no ads and, most importantly, absolutely no data collected. 🏆

This app fixed an issue that has been plaguing my android phone since I bought it. The lightest tap or movement of my wired headphones would cause my phone to freak out and skip/pause music and randomly adjust the volume up/down. With this app I mapped the "headset button" trigger to "do nothing" and now it's fixed! Any one with the same issue needs to use this app.

I think it's a really cool app, if I had any suggestions I would think it should allow a button to initiate a swipe across a portion of the screen chosen. And also a a button assignment to press one section of the screen, so controllers can be used for apps that don't support controllers. I don't know if it would be hard but I think it's a cool idea. Thanks for all the effort tho. 😊😊

What's new

Action for doing pinches and swipes on the screen with 2 or more fingers. Many thanks to Tino (@pixel-shock) for working on this feature. 😊
