How do you safely remove the broken back glass of an iPhone?
Removing the broken back glass is the most delicate part of the repair. The glass is glued firmly to the frame, and improper removal can damage internal components like the camera or wireless charging coil.
Start by powering off the iPhone to prevent short circuits. Use a heat gun or iOpener to warm the edges of the back glass. This softens the adhesive, making it easier to separate the glass from the frame.
After heating, place a suction cup near the edge and gently lift to create a small gap. Insert a plastic opening pick or spudger into the gap and carefully slide it around the edges to break the adhesive bond. Avoid using metal tools to prevent scratches or cracks.
If the glass is shattered, wear safety gloves and eye protection to avoid injury from glass shards. Take your time and reheat if the adhesive becomes too stiff. Once the glass is free, disconnect any cables attached to the rear panel before fully removing it.
