4. Installation Guide

Replacing a phone screen requires careful handling and attention to detail. We strongly recommend professional installation if you are not experienced in electronic device repair. If you choose to proceed with self-installation, please follow these precautions carefully.

Important Installation Precautions:

1. Pre-Installation Test: Before proceeding with full installation, check whether the product is in good condition and test it thoroughly. Do not remove protective film or labels during testing.
2. Static Electricity: Be mindful of static electricity issues. Static discharge can damage electronic components. Consider using an anti-static wrist strap.
3. Fragile Component: The screen is made of glass and is very fragile. Handle with extreme care. Testing before installation is strongly recommended.
4. Flex Cable Handling: Do not bend the flex cable excessively. During installation and testing, ensure the LCD cable is not bent at an angle greater than 90 degrees, as this can result in a black screen.
5. Power Buttons/Volume Buttons: The replacement screen does not include power buttons, volume buttons, or other small components. You will need to carefully remove these from your old screen and re-install them onto the new assembly.

6. Maintenance and Care

To ensure the longevity and optimal performance of your new screen, follow these maintenance guidelines:

• Screen Protection: Consider using a screen protector and a protective case to prevent scratches and accidental damage.
• Cleaning: Clean the screen with a soft, lint-free cloth. Avoid harsh chemicals or abrasive materials that could damage the display.
• Avoid Pressure: Do not apply excessive pressure to the screen, as this can cause internal damage.
• Temperature Extremes: Avoid exposing your device to extreme temperatures, which can affect screen performance and lifespan.

7. Troubleshooting

If you encounter issues after installation, refer to the following common troubleshooting steps:

• Black Screen After Installation: If your phone displays a black screen, press and hold the power key and volume key simultaneously. If the phone vibrates, it often indicates that the main flex cable is not installed properly. Power off the device and carefully reinstall the product, ensuring all connections are secure.
• Unresponsive Touch: Check the flex cable connection for the digitizer. Ensure it is fully seated and not damaged.
• Display Anomalies (lines, flickering): This could indicate a loose display flex cable or potential damage during installation. Recheck the display cable connection.
• Screen Not Fitting Properly: Ensure all old adhesive residue is removed from the phone frame before applying the new screen.
