5. Maintenance and Care
- Cleaning the Case: To clean the phone case, remove it from your device. Wipe it gently with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, followed by rinsing with clean water and air drying. Avoid harsh chemicals or abrasive materials.
- Cleaning the Screen Protector: Use a microfiber cloth to wipe the screen protector. For smudges, a screen cleaning spray designed for electronics can be applied to the cloth (not directly to the screen) and then wiped.
- Avoid Extreme Conditions: Do not expose the case or screen protector to extreme temperatures, direct sunlight for prolonged periods, or corrosive liquids, as this may cause damage or discoloration.
6. Troubleshooting
- Bubbles under Screen Protector: If small bubbles remain after installation, try gently pushing them towards the nearest edge with a soft cloth. For larger bubbles, carefully lift the nearest edge of the protector slightly to release the air, then re-apply. Ensure the screen is dust-free before re-application.
- Case Fit Issues: Ensure you have the correct model of phone (IPRO Y300) for this case. If the case feels loose or too tight, double-check that your phone is properly seated within the case and that no foreign objects are obstructing the fit.
- Ring Holder Stiffness: The ring holder is designed to be firm to maintain its position as a kickstand. If it feels too stiff, gently rotate it a few times to loosen the mechanism. Avoid excessive force.
