iPhone 12 Back Glass Replacement

 Introducing

Apple has added MacSafe to the iPhone 12 series. While trying to disassemble the rear window, we found that the magnets were stuck in the rear window. Of course, the difficulty of restoring the glass behind the iPhone 12 series has increased. With our vast experience and the right tools, we have found the right way to fix the next iPhone 12 glass.

Disconnect the phone and remove the wireless charging coil. Next, scan the rear window with a laser, with no room for the camera. Then we remove the magnetic thread and the rear window. Insert a new window with large camera holes. Check the type of magnet and the screen on the rear glass. The guide above provides a clear and concise guide on how to replace the iPhone 12 back cover. However, the journey to find the right path was not easy. We tried first and almost got it. Scroll down and you will see the challenges we face.
