Setup and Pre-Installation Testing

Before proceeding with the full installation, it is crucial to perform a pre-installation test of the new LCD assembly. Do not remove any protective films or tags from the new screen during this test.

1. Power Off: Ensure your Umidigi UMI Note 100A / Note 100 5G is completely powered off.
2. Open Device: Carefully open your phone to access the internal components. This typically involves heating the edges of the old screen to soften adhesive and using prying tools to separate it from the frame.
3. Disconnect Old Screen: Disconnect the flex cables of the old screen from the motherboard.
4. Clean Connections: Gently clean the flex cable connectors on the new screen and the corresponding slots on the motherboard using a soft, dry cloth or isopropyl alcohol if necessary.
5. Connect New Screen: Connect the flex cables of the new LCD assembly to the motherboard tightly. Ensure all connections are secure.
6. Battery Check: Verify that the phone's battery is sufficiently charged. Ensure the motherboard is not damaged.
7. Power On and Test: Power on the phone. Test the display functionality (brightness, colors, dead pixels) and touch screen responsiveness across the entire screen. Check for any ghost touches or unresponsive areas.
8. Power Off: If the test is successful, power off the phone before proceeding with the full installation. If issues are found, contact support before attempting full installation.

Important: The return of screens with installation attempts or removed protective films/tags may not be accepted if issues are discovered after these actions. Test thoroughly first.

Installation Instructions

This section outlines the general steps for replacing the LCD assembly. Specific disassembly and reassembly steps may vary slightly depending on your phone's exact internal design. Refer to device-specific repair guides if available.

1. Prepare Workspace: Ensure a clean, well-lit, and static-free workspace.
2. Power Off: Confirm the phone is powered off and disconnected from any power source.
3. Remove Back Cover: Carefully remove the phone's back cover. This may involve heating the edges and using prying tools.
4. Disconnect Battery: Locate and disconnect the battery flex cable from the motherboard to prevent accidental power-on during the repair.
5. Remove Old Screen:
   • Apply heat to the edges of the old screen using a heat gun or hairdryer to soften the adhesive.
   • Use a suction cup to create a gap, then insert thin prying tools around the perimeter to carefully separate the old screen from the phone frame.
   • Once loose, disconnect any remaining flex cables connecting the old screen to the motherboard and remove it.
6. Clean Frame: Thoroughly clean the phone frame, removing all traces of old adhesive and glass fragments. This is crucial for proper seating of the new screen.
7. Apply New Adhesive: Apply new adhesive strips or a thin bead of B-7000 glue (not included) around the perimeter of the phone frame where the screen will sit.
8. Connect New Screen: Carefully connect the flex cables of the new LCD assembly to the motherboard. Ensure they are seated correctly and securely.
9. Install New Screen: Align the new LCD assembly with the phone frame and gently press it into place. Ensure it sits flush and evenly.
10. Reconnect Battery: Reconnect the battery flex cable to the motherboard.
11. Reassemble Phone: Reattach the back cover and secure any screws or clips that were removed.
12. Final Test: Power on the phone and perform a final test of the display and touch functionality.

Caution: Do not force the installation. If you encounter resistance, re-check alignment or for any obstructions. Incorrect installation can damage the screen or phone.

Operating (Post-Installation)

After successful installation and reassembly:

• Initial Power On: Power on your device. The boot sequence may take slightly longer than usual after a hardware change.

• Charging: Ensure the device charges normally.

Maintenance

To ensure the longevity and optimal performance of your new LCD display:

• Screen Protector: Consider applying a high-quality screen protector immediately after installation to prevent scratches and minor impacts.
