Screen replacement requires careful handling and technical knowledge. Professional installation is highly recommended.

4.1. Important Precautions

• Fragile Product: The screen is fragile. Exercise extreme caution when unpacking and handling.
• Power Off: Always turn off your device completely before beginning the installation.
• Static Discharge: Perform a static mode simulation test before full installation to prevent electrostatic discharge (ESD) damage.

• Avoid Excessive Force: Do not apply excessive force to the screen corners during installation, as this can easily crack the screen.
