If your back cover glass is accidentally broken, there are two ways to repair it, one is to go to the official after-sales service, and the other is to go to a third-party repair point for repair.
Generally, if your back cover is accidentally broken, if you go to the after-sales service for maintenance, if your display screen and rear camera are no problem, then the after-sales service will replace all accessories except the display screen and rear camera for you. This repair Plans apply to all iPhone 12 series, with repairs ranging from $349 to $599
All after-sales repair shops repair in the same way. They will not replace the back cover glass for you alone. If your iPhone 12 is dropped and the back cover is broken and the screen is also faulty, you can only replace the whole machine.
Most of the third-party repair shops can replace the rear cover glass, and the price varies according to the quality of the rear cover glass and the way of repair. It should be noted that there are no original accessories for the individually replaced back cover glass. If you need to replace the original back cover, you can only replace the disassembly accessories with the middle frame.
At present, the mainstream professional repair shops on the market usually use a laser machine to polish the rear cover, and then heat it at a low temperature to remove the damaged glass, remove it and clean it, and then install a new glass. This repair method is the current maintenance method. The least damage to the mobile phone, not only does not need to disassemble and high temperature baking, basically zero damage to the mobile phone.
The disadvantage is that the cost of laser equipment is high, and not all repair shops have laser replacement equipment.
There are also some unprofessional repair shops that basically use a hot air gun to directly bake the forced glass. This repair method is simple and rude, and it still has a relatively large impact on the machine. If so, the phone flash cannot be turned on, etc.
