1. Introduction
This manual provides essential information for the proper installation, use, and maintenance of your new Slim Ultra Thin Silicone TPU Case. Designed to offer protection while maintaining a sleek profile, this case is compatible with a range of Doogee Note and N series smartphone models. Please read these instructions carefully to ensure optimal performance and longevity of your product.
2. Setup and Installation
Installing your TPU case is a straightforward process. Follow these steps to ensure a secure fit:
- Prepare Your Device: Ensure your Doogee smartphone is clean and free of dust or debris. Gently wipe the phone's surface with a soft, dry cloth.
- Align the Case: Hold the case with the camera cutout aligned with your phone's camera module.
- Insert One Side: Carefully insert one side of your phone into the case, starting with the top or bottom edge.
- Gently Press On: Apply gentle pressure around the edges of the phone, working your way around until the entire phone is securely seated within the case. The flexible TPU material allows for easy installation.
- Check Fit: Once installed, ensure all edges of the phone are covered by the case and that all cutouts (camera, ports, buttons) are properly aligned.


3. Operating Your Device with the Case
The Slim Ultra Thin Silicone TPU Case is designed to provide protection without hindering your phone's functionality.
- Button Access: The case features precise button covers that allow for easy and responsive pressing of volume and power buttons.
- Port Access: Accurate cutouts ensure full access to charging ports, headphone jacks (if applicable), and speakers without needing to remove the case.
- Camera Protection: The raised bezel around the camera cutout helps protect the camera lenses from scratches when the phone is placed on flat surfaces.


4. Maintenance and Care
To keep your TPU case looking new and performing effectively, follow these simple maintenance guidelines:
- Cleaning: Regularly clean your case with a soft, damp cloth. For tougher stains, a small amount of mild soap can be used. Rinse thoroughly and allow to air dry completely before re-installing on your phone.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, alcohol, or harsh chemicals, as these can damage the TPU material and affect its clarity or color.
- Storage: When not in use, store the case in a cool, dry place away from direct sunlight to prevent discoloration or material degradation.
5. Troubleshooting
Most issues with phone cases are minor and easily resolved:
- Case Doesn't Fit: Ensure you have selected the correct model for your Doogee smartphone. Double-check your phone's model number against the compatibility list.
- Buttons Are Stiff: New cases may have slightly stiffer button covers. With regular use, they should become more pliable. Ensure the case is fully seated around the phone.
- Discoloration (for Clear Cases): Over time, clear TPU cases may exhibit a slight yellowing due to UV exposure and natural material aging. This is normal for TPU and does not affect the protective qualities of the case.
