- Buttons are not responding in game:
- Verify that the controller is paired in the correct operating mode for the specific game you are playing (e.g., GamePad Mode for most Android games, iCade Mode for iCade iOS games).
- Check the game's settings to ensure it supports external controllers and that the controls are mapped correctly.
