I got an iPhone 6 PLus with broken DIsplay Bezel. The Glas and the LCD are not broken or something else. Is it possible to remove and change the bezel against a new one without damaging the Glas?
It really depends on how you plan to do it. The way I do it is I heat up the display, then carefully removed the frame. This will scratch up the glass and you will also destroy your small pieces like camera and sensor brackets. I have a framing machine to replace the frame, which is the only dependable way of doing it. You can try to hot glue it, but it will be very weak and probably lift. So the answer is: Yes you can. No you shouldn’t.
