Question

why is it recommend when replacing the back glass on any new iPhone (8 or later) you should use a laser machine

In: Technology

Answer 1

Because the glass is glued onto the back so hard that trying to lever it off either just breaks it into even tinier chunks or you rip off the back panel of the phone. You need to burn the glue away behind the glass.
