Preparation

  • Gather all necessary tools and replacement parts.

  • Work on a clean, well-lit surface.

  • Always wear an anti-static wrist strap.

  • Power off the phone completely.

Disassembly

  • Use a heat gun to soften the screen adhesive (around 70°C / 158°F).

  • Gently lift the screen using a suction cup.

  • Insert a plastic pick and slowly slide it around the edges.

  • Take care not to damage the ribbon cables when opening the screen.

Key Operation Points

  • Always disconnect the battery before removing any ribbon connectors.

  • Use the correct screwdriver bit size to avoid stripping screws.

  • Label or photograph screw placement for accurate reassembly.

  • Handle small parts like the Home button and earpiece speaker with care.

Reassembly

  • Test the new screen before final installation.

  • Clean off any old adhesive residue.

  • Apply new waterproof adhesive strips.

  • Reinstall all components in the correct order.

Common Beginner Mistakes

  • Applying too much force and tearing ribbon cables.

  • Ignoring differences in screw length or type.

  • Forgetting to reinstall important shielding plates.

  • Skipping a full functionality test after assembly.

Pro Tips for Advanced Repairs

For curved or foldable screens, it’s recommended to:

  • Use a professional screen separator machine.

  • Work in a dust-free environment.

  • Apply UV-curing adhesive for better sealing.

  • Use a screen tester to check display performance.
