What You’ll Need

Before you start, gather these tools and parts:

Plastic opening picks
Small Phillips screwdriver
Tweezers

🪛 Step-by-Step Repair Guide

Step 1: Power Off and Prepare

Turn off your Galaxy Z Flip completely.
Remove the SIM card tray.
Place the phone on a clean, static-free surface.

Step 2: Heat the Back Cover

Use a heat gun or iOpener to gently warm the back glass (around 80°C / 176°F).
