Setup and Installation
Follow these steps to properly install your Dexnor case:
- Separate the Case: Gently pry apart the front frame from the back cover. Locate the small notch on the side of the case to assist in separation.
- Clean Your Device: Use a soft, lint-free cloth to thoroughly clean your Samsung Galaxy S25 Ultra screen and back to remove any dust or smudges.

Troubleshooting
Fingerprint Reader Issues
If you experience difficulty with the fingerprint reader when using the built-in screen protector:
- Ensure your screen is clean and free of dust or moisture.
- Re-register your fingerprints after installing the case. This can improve recognition accuracy.

Case Not Closing Properly
If the case does not close securely:
