2. Setup and Installation Guide

Replacing a phone screen requires careful attention. It is recommended that non-professionals seek assistance from a local mobile phone repair shop to ensure safe and efficient replacement.

2.1 Pre-Installation Testing

Before proceeding with full installation, it is crucial to test the new screen assembly. Connect the screen flex cable ONLY to the motherboard without removing any components from the new screen. Record a video of the entire testing process. If any issues arise during this test, stop immediately and contact customer service.

2.2 Installation Steps (General Guidance)

  1. Disconnect Battery: Always disconnect the phone's battery first to prevent short circuits.
  2. Use Proper Tools: Use plastic tools (not metal) to avoid scratching components.
  3. Follow a Teardown Guide: Refer to a specific teardown guide for your phone model (e.g., iFixit or YouTube tutorials) for detailed instructions.
  4. Adhesive Application: When reassembling, always apply new adhesive strips or B7000 glue to ensure water resistance and stability. Do not reuse old adhesive.

2.3 Screen Type Considerations

Understanding 'With Frame' vs 'No Frame' LCDs.
  • LCD With Frame: The touch screen, display, and frame are glued together. This option is generally easier to install as you only need to replace the entire display part.
  • LCD No Frame: The touch screen and display are glued together, but there is no frame. You will need to transfer your old frame to the new assembly, which can be more challenging. For beginners, the 'LCD With Frame' option is recommended.

4. Maintenance

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

  • Cleaning: Use a soft, lint-free cloth slightly dampened with water or a screen cleaner to gently wipe the display. Avoid harsh chemicals or abrasive materials.
