Yes, yes you can pull it off without any damage to the screen whatsoever. The glue cures into a gummy gel type substance not a crispy hard rock type substance. In my experience, I've been able to remove the glass without any trace on the screen with little to no effort.
That's the biggest thing I was worried about. As the rock hard type that would essentially cracked the screen. Is it easy or difficult to do. Sorry I'm asking so many questions I'm just very unsure about something like this which I've never put glue on my phone before
