I’ve tried using a heat gun and a suction cup, a razor blade and pry tools, but none of them work. Im about to use isopropyl alcohol to dissolve the glue of the screen, but I’m not sure if this is safe.
Isypropl Alchohol will more than likely not help aid in the removal of glue and will more than likely damage Face ID sensors or water indicators inside of the phone. Try using a larger/stronger suction cup or keep the heat on the phone for longer.
No alcohol needed, just apply firm and constant force, it will eventually release.
