4. Installation Instructions (Operating)

This screen replacement comes with a frame, which simplifies the installation process compared to screen-only replacements. The frame provides a pre-assembled structure, reducing the risk of damage during installation.

1. Disassemble Old Screen: Carefully remove the back cover, battery, and any components obstructing access to the old screen assembly. Disconnect all flex cables from the old screen.
2. Remove Old Frame (if applicable): If your original screen was not integrated with a frame, you will need to transfer internal components to the new frame. If your old screen was also with a frame, remove the entire old frame assembly.
3. Transfer Components: Transfer necessary components (e.g., earpiece speaker, front camera, vibration motor, buttons) from your old phone frame to the new screen's frame.
4. Connect New Screen: Carefully connect the new screen's flex cables to the corresponding connectors on the phone's motherboard.
5. Reassemble Device: Reinstall the battery, back cover, and any other components in reverse order of disassembly. Ensure all screws are tightened appropriately.
6. Final Test: Power on your device and perform a thorough test of all screen functions, including touch, display quality, and brightness.
