BT Layouts Xiaomi ROOT is a free Android app that enables you to install and remove layout files for Xiaomi Bluetooth remote control and game controller. The app requires root access and modifies system files on your device. Once the layout files are installed, you may remove the app, but the layout files will remain installed.

It's important to note that this app won't fix any Bluetooth issues you might have when connecting to the remote or game controller, nor will it help you with pairing. Instead, it adds layout files that enable Android to interpret the key presses on the controllers. MIUI-based ROMs already have layout files for the controllers, so this app is mainly useful for non-MIUI users.
