• Use a screen protector for added scratch resistance.
• Clean the screen with a soft, lint-free cloth, avoiding harsh chemicals.

5. Troubleshooting

5.1 Common Issues and Solutions

• Black Screen After Installation: If your phone displays a black screen after installation, press and hold the power key and volume key simultaneously. If the phone vibrates, it indicates that the main flex cable may not be properly installed. Power off the device and carefully reinstall the screen assembly, ensuring all connections are secure.
• Touch Not Responding: Ensure all flex cables are correctly seated and not damaged. Re-test the screen.
• Display Anomalies (Lines, Discoloration): This could indicate a damaged flex cable or an issue with the screen itself. Recheck connections. If the issue persists, contact support.

5.2 Professional Assistance
