5. Maintenance
To ensure the longevity and appearance of your LeYi phone case, follow these maintenance tips:
- Cleaning: Use a soft, damp cloth to wipe down the exterior of the case. Avoid harsh chemicals or abrasive cleaners, as these can damage the material.
- Regular Inspection: Periodically remove the case and inspect your phone and the case for any trapped dirt or debris that could cause scratches. Clean as necessary.
- Avoid Extreme Conditions: Do not expose the case to extreme temperatures or prolonged direct sunlight, which can degrade the material over time.
6. Troubleshooting
If you encounter any issues with your LeYi case, consider the following:
- Case Not Fitting Correctly: Double-check that your phone model is indeed the Samsung Galaxy S10 (6.1 inch) and not an S10E, S10 Plus, or S10 Lite. Ensure all three layers of the case are correctly aligned and snapped into place during installation.
- Buttons Unresponsive: Verify that the flexible button covers are properly seated over your phone's buttons. Re-install the case if necessary to ensure correct alignment.
- Fingerprint Recognition Issues: If you experience difficulty with fingerprint recognition, ensure the screen area is clean and free of air bubbles or dust. Some users may need to re-register their fingerprints after installing the case to optimize performance.
