Before the iPhone 12, replacing the rear glass was a relatively straightforward task with the right equipment. However, with the introduction of MagSafe, this task has become highly specialized. I've witnessed numerous failed attempts at repairs in local shops, leading to further fixes needed to rectify their mistakes.
One memorable incident involved an iPhone 13 Pro that had been previously repaired at a local center in Market Harborough. The customer reported that the phone became hot and shut off. Upon investigation, I discovered that the repair technician had accidentally pierced the battery while replacing the rear glass. This mistake resulted in a strong chemical smell, posing a significant fire risk. With great caution, I removed the damaged battery and replaced it with a new one, resolving the issues.
Such incidents underscore the importance of avoiding shortcuts during repairs. Proper rear glass replacement involves several crucial steps to prevent damage to internal components, including the camera, logic board, Face ID, flash, and battery. These components must be removed before safely heating the glass off or utilizing specialized equipment like a laser machine to dissolve the adhesive.
Despite the complexity, I've mastered the process through extensive experience, having completed hundreds of rear glass replacements. One final step involves replacing the magnets, which are often removed along with the old glass. This ensures the proper functioning of MagSafe features and wireless charging capabilities.
