4. Maintenance and Care
To maintain the appearance and protective qualities of your Tech21 Evo Tactical case:
- Cleaning: Wipe the case regularly with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used. Avoid harsh chemicals or abrasive cleaners.
- Material: The case is made from Thermoplastic Polyurethane (TPU) with FlexShock technology. This material is durable but can be affected by extreme temperatures or prolonged exposure to direct sunlight.
- Inspection: Periodically inspect the case for any signs of wear or damage. If the case is significantly damaged, its protective capabilities may be compromised.
5. Troubleshooting
If you encounter any issues with your Tech21 Evo Tactical case, consider the following:
- Loose Fit: Ensure the case is correctly installed and fully seated around all edges of your Samsung Galaxy Note5. Remove and re-install the case if necessary.
- Button Difficulty: New cases may have slightly stiffer button covers. With regular use, these will typically soften and become easier to press. Ensure the phone is properly aligned within the case.
- Stylus Access: While designed for easy access, some users may find the S Pen slightly more recessed. Ensure your finger or nail can comfortably reach and extract the stylus.
- Charging Issues: If wireless charging is not working, ensure your phone is correctly positioned on the wireless charger. If using a cable, ensure the cable is fully inserted into the port.
