Fingerprint Sensor

The built-in screen protector includes a dedicated area for the ultrasonic fingerprint sensor. For optimal performance, it is recommended to re-register your fingerprints after installing the case. Ensure the fingerprint area on the screen protector is clean and free of dust or moisture when registering and using your fingerprint.

Maintenance

  • Cleaning: Use a soft, lint-free cloth to clean the case and screen protector. For stubborn smudges, a small amount of water or a mild screen cleaner can be applied to the cloth, not directly to the case.
  • Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or harsh chemicals as these can damage the case material and screen protector.
  • Regular Inspection: Periodically inspect the case for any signs of wear or damage. If the case is significantly damaged, consider replacing it to maintain optimal protection.

Troubleshooting

  • Fingerprint Sensor Issues: If the fingerprint sensor is not responding or is inconsistent, try the following:
    1. Ensure the fingerprint area on the screen protector is clean and dry.
    2. Re-register your fingerprints with the case installed. This helps the phone recognize your print through the screen protector.
    3. Apply slight pressure when scanning your fingerprint.
  • Case Not Closing Properly: Ensure your phone is correctly seated within the front frame and that no debris is preventing the front and back pieces from snapping together.
  • Reduced Touch Sensitivity: If you experience reduced touch sensitivity, ensure the screen protector is clean and free of air bubbles. Re-registering your touch sensitivity settings in your phone's display options may also help.
