A. 1. Reconfigure the button: Go to Settings > Controls > Touch Control and check the configuration for the Rapid Fire button. Ensure it is set up correctly and not overlapping with other buttons. 2. Test with different games: Sometimes, the Rapid Fire feature may not work with certain games. Test it with different titles to see if it functions properly.

B. 3. Use an external controller: If the Rapid Fire button remains unresponsive, consider using a Bluetooth controller that has a rapid-fire feature, which may provide a more reliable experience.
