5. Setup and Installation

Replacing an iPhone screen requires careful attention to detail. We highly recommend watching a professional installation video for your specific iPhone Xs Max model before attempting the replacement. This will familiarize you with the procedures and help avoid unnecessary damage.

Important Considerations:

• Power Off: Ensure your iPhone is completely powered off before starting.
• Organize Screws: Keep track of all screws removed, as they vary in size and location. Using a magnetic mat or labeled compartments is recommended.
• Handle with Care: The flex cables are delicate. Avoid bending or tearing them.
• Transfer Components: You will need to transfer certain components (e.g., home button, front camera, earpiece speaker) from your original screen to the new replacement screen.

General Installation Steps (Refer to video for detailed steps):

1. Remove the two pentalobe screws at the bottom edge of the iPhone.
2. Use a suction cup and prying tool to carefully open the screen assembly from the phone body.
3. Disconnect the battery and display flex cables from the logic board.
4. Carefully remove the original screen assembly.
5. Transfer the necessary components (e.g., front camera assembly, earpiece speaker, sensor bracket) from the old screen to the new SRJTEK screen.
6. Connect the new screen's flex cables to the logic board.
7. Reconnect the battery.
8. Before fully sealing, power on the phone and test the new screen's functionality (touch, display, brightness).
9. If all functions are satisfactory, carefully align and press the new screen into place, then reinsert the bottom screws.

6. Operating and Testing

After installation, it is crucial to perform a thorough test of the new screen's functionality:

• Power On: Turn on your iPhone.
• Touch Functionality: Test the touch response across the entire screen. Drag an app icon around the screen to check for dead spots.
• Display Quality: Check for any discoloration, dead pixels, or lines on the display.
• Brightness and Color: Adjust brightness settings to ensure proper functionality and check color accuracy.
• 3D Touch/Haptic Touch: Verify that pressure-sensitive touch features work correctly.
• Front Camera and Sensors: Test the front camera, proximity sensor (during calls), and ambient light sensor (auto-brightness).
• Earpiece Speaker: Make a test call to ensure the earpiece speaker functions.

If any issues are detected during testing, refer to the Troubleshooting section or contact SRJTEK support.

7. Maintenance

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

• Clean Gently: Use a soft, lint-free cloth (e.g., microfiber) to clean the screen. Avoid abrasive materials.
• Avoid Harsh Chemicals: Do not use window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia, or abrasives to clean the screen.
• Protect from Drops: While the screen has 9H hardness, severe impacts can still cause damage. Consider using a protective case and the provided screen protector.
• Avoid Extreme Temperatures: Do not expose your device to extreme hot or cold temperatures, as this can affect screen performance and battery life.
