The Xbox Wireless Controller is compatible with Android devices, allowing you to use it wirelessly via Bluetooth. This means it should work well with services like GeForce Now (GFN) on Android. All buttons and joysticks should be detectable by hardware testing tools like those on hardwaretester.com/gamepad, given the controller's Bluetooth connectivity and compatibility with Android platforms. If you encounter any issues, ensure your Android device supports Bluetooth and that the controller is properly paired.
