Maintenance
To maintain the appearance and protective qualities of your Sonix case, follow these simple guidelines:
- Cleaning: Wipe the case regularly with a soft, damp cloth. For stubborn stains, a mild soap solution can be used. Avoid harsh chemicals or abrasive cleaners, as these may damage the case's finish or design.
- Avoid Extreme Conditions: Prolonged exposure to direct sunlight or extreme temperatures can affect the material and color of the case.
Troubleshooting
If you encounter any issues with your Sonix case, consider the following:
- Improper Fit: Ensure the case is designed specifically for the iPhone 15 Pro Max. Using a case intended for a different model may result in a loose fit or obstructed ports/buttons.
- MagSafe Not Attaching: Verify that there are no obstructions between the case and the MagSafe accessory. Ensure the accessory itself is MagSafe compatible.
- Discoloration: Over time, clear cases made from TPU may exhibit slight yellowing due to UV exposure. This is a natural characteristic of the material and does not affect the protective function of the case.
