Important Considerations Before Installation:
- No Manual Included: This product does not come with a printed installation manual. Please refer to online video tutorials (e.g., on YouTube) for detailed installation steps.
- Identify Malfunction Cause: Before purchase and installation, ensure that your phone's malfunction is indeed caused by the LCD or touch panel, and not other components.
- Fragile Component: The LCD is a fragile component. Handle with extreme care during the entire process. Glass fragments may cause injury if broken.
- Static Electricity: Pay close attention to static electricity issues. Ground yourself using an ESD (Electrostatic Discharge) wrist strap to prevent damage to electronic components.

It is crucial to test the product thoroughly before full installation. Do not remove any protective films or labels during this test.

Maintenance
To ensure the longevity and optimal performance of your new LCD display, follow these maintenance guidelines:
- Cleaning: Use a soft, lint-free cloth slightly dampened with water or a screen cleaner specifically designed for electronics. Avoid harsh chemicals or abrasive materials.
- Protection: Always use a protective case and a screen protector to guard against drops, scratches, and impacts.

- Ensure all flex cables are securely connected to the motherboard.
