Important Note on Screen Type:
This product features an INCELL/TFT screen. It is important to note that INCELL/TFT screens are generally smaller in size compared to AMOLED screens and do not support in-display fingerprint sensors.

3. Installation Precautions and Setup
Careful adherence to these precautions is essential for a successful installation and to prevent damage to the new screen or your device.
- Pre-Installation Check and Test: Before proceeding with full installation, thoroughly inspect the product for any physical damage. It is strongly recommended to test the screen functionality (display and touch) without fully installing it. Do not remove any protective films or labels during this testing phase. Be mindful of static electricity, which can damage electronic components.
- Fragile Component: The screen is made of glass and is very fragile. Handle it with extreme care throughout the entire process.
- Flex Cable Handling: The LCD flex cable is delicate. Do not bend it excessively. Bending the cable at an angle greater than 90 degrees can cause permanent damage, leading to a black screen or display malfunctions.
- Professional Installation Recommended: If you lack experience in electronic device repair or are not confident in your ability to perform the replacement, it is highly 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 their steps carefully.

4. Operating and Testing the Screen
After connecting the new screen, but before fully assembling the device, perform the following tests:
- Display Test: Power on the device and check for any abnormalities in the display, such as dead pixels, lines, or incorrect colors.
- Touch Function Test: Navigate through the phone's interface, open applications, and type to ensure the touch screen is fully responsive and accurate across the entire display area.
- Brightness Adjustment: Verify that the screen's brightness can be adjusted correctly.

5. Troubleshooting
- Black Screen After Installation: If your phone displays a black screen after connecting the new display, simultaneously press and hold the power key and volume key. If the phone vibrates, it indicates that the main flex cable or the screen's flex cable may not be properly seated. Disconnect and carefully reconnect the screen's flex cable, ensuring a secure connection.
- Unresponsive Touch or Display Issues: Recheck all cable connections. Ensure no flex cables are bent or damaged. If issues persist after re-seating connections, the screen itself may be faulty, or there might be an underlying issue with the phone's motherboard.
- Screen Not Fitting Properly: Double-check that you have the correct screen model for your specific phone. Refer to the compatibility section.
6. Maintenance
To ensure the longevity and optimal performance of your new screen:
- Protective Film: Keep the included tempered film on the screen to protect against scratches and minor impacts.
- Cleaning: Use a soft, lint-free cloth, preferably microfiber, to clean the screen. Avoid harsh chemicals or abrasive materials.
- Avoid Pressure: Do not apply excessive pressure to the screen, as this can damage the display or touch digitizer.
- Temperature Extremes: Avoid exposing your device to extreme temperatures, which can affect screen performance and lifespan.
