Step-by-Step Installation:

- Disconnect Battery: Locate and disconnect the battery flex cable to prevent short circuits.
- Remove Old Screen: Disconnect the old screen's flex cables. Apply heat to the front edges of the phone to soften the adhesive holding the old screen. Carefully pry and remove the damaged screen assembly.

Maintenance and Care
- Screen Protection: Consider using a screen protector (tempered glass or film) to prevent scratches and minor impacts.
