Maintenance
To keep your Nillkin case in optimal condition, follow these simple maintenance tips:
- Regular Cleaning: Wipe the case regularly with a soft, damp cloth to remove dust, dirt, and fingerprints. Avoid using harsh chemicals or abrasive materials, as these can damage the case's finish.
- Avoid Extreme Temperatures: Do not expose the case to extreme heat or cold, as this can affect the material's integrity and fit.
- Inspect for Damage: Periodically check the case for any signs of wear or damage, especially around the hinge and corners. If significant damage is observed, consider replacing the case to ensure continued protection for your device.
Troubleshooting
If you encounter any issues with your Nillkin case, please refer to the following common solutions:
- Case Not Fitting Properly: Ensure that the case is compatible with your specific model (Samsung Galaxy Z Fold 7 5G). Remove and re-install both the backplate and front frame, making sure they snap securely into place without any gaps.
- Hinge Movement Issues: Verify that no debris is lodged in the hinge mechanism. The patented rebound hinge is designed for smooth operation; if it feels stiff, gently open and close the phone several times to ensure proper seating.
- Screen Protector Interference: If you are using a screen protector, ensure it is correctly installed and compatible with the case's front frame. The front frame is designed to guide screen protectors, but improper installation of the screen protector itself can cause issues.
If problems persist, please contact Nillkin customer support for further assistance.
