5. Troubleshooting
5.1 Connectivity Issues
- Controller not connecting: Ensure the controller is charged and the correct platform mode is selected on the back switch. Try re-pairing or connecting via USB cable.
- Bluetooth adapter issues: Ensure the adapter is securely plugged into a working USB port. Try a different USB port.
5.2 Button/Joystick Malfunctions
- Stick drift: The Hall Effect joysticks are designed to prevent drift. If experiencing issues, try recalibrating through the KeyLinker app or performing a factory reset.
- Rear button remapping issues: Be aware that remapping rear buttons by holding them for 3 seconds can inadvertently trigger remapping mode. Avoid holding these buttons for extended periods during gameplay if they are mapped to actions that require continuous input. Mappings are subject to other button configurations.
5.3 App-Related Issues (KeyLinker)
- App not connecting to controller: Ensure Bluetooth is enabled on your mobile device and the controller is in a compatible mode.
- Settings not saving: After making changes in the app, ensure they are applied or saved to the controller's profile. Configurations are saved on the controller itself.
5.4 Specific Game Compatibility
- Call of Duty Mobile: This game may have limited controller support. The controller might work partially in 'Touch' mode (joysticks only) or require third-party remapper apps for full functionality. Android mode may not be recognized.
