Installation Precautions

Careful adherence to these precautions is crucial for a successful screen replacement:

1. Pre-Installation Test: Before full installation, check the product's condition and test its functionality. Do not remove any protective film or labels during this testing phase. Be mindful of static electricity issues.
2. Fragile Component: The screen is made of glass and is very fragile. Testing before installation is highly recommended to ensure it is working correctly.
3. Flex Cable Handling: Do not bend the LCD cable excessively. During installation and testing, ensure the LCD cable is not bent more than 90 degrees, as this can result in a black screen.
4. Professional Installation: If you are not experienced in phone repair or electronic equipment maintenance, it is recommended to seek assistance from a professional repair shop. This can save time and prevent potential damage. Alternatively, search for relevant installation videos on platforms like YouTube and follow the steps carefully.

Operating and Testing

After connecting the new screen, it is essential to test its functionality before fully assembling the device:

• Power on the device and check for display issues such as incorrect response, pixel distortion, or wrong colors.
• Test the touch screen digitizer for responsiveness and accuracy across the entire screen.
• Ensure there are no dead zones or lines on the screen.

Maintenance

To prolong the life of your new screen and maintain its performance:

• Avoid dropping your phone or subjecting it to strong impacts.
• Keep the screen clean using a soft, lint-free cloth. Avoid harsh chemicals.
• Use the provided tempered film for additional protection against scratches and minor impacts.
• Avoid exposing the phone to extreme temperatures or direct sunlight for extended periods.

Troubleshooting

If you encounter issues after installation, consider the following:

• Black Screen: If your phone displays a black screen after installation, press and hold the power key and volume key simultaneously. If the phone vibrates, it may indicate that the main flex cable is not properly installed. Reinstall the product, ensuring all connections are secure.
• Unresponsive Touch/Display Issues: Double-check all flex cable connections. Ensure they are fully seated and not bent or damaged. A loose connection is a common cause of such problems.
• Professional Help: If problems persist after attempting basic troubleshooting, it is strongly recommended to consult a professional repair technician.
