Even if unbroken, here's how to easily remove a tempered glass screen protector from any smart phone. Hope it is helpful :) Music credits: Craves - By My Side 0:00
If you are worried about tiny bits of glass falling off as you peal it off, you can try covering the screen protector with tape. Then when you peal it off all the tiny pieces should be held in place.
I broke mine in about a week. I just broke it even more five minutes ago. I ran crying to RU-vid or see if the protecter actually sounds and looks like actual broken glass. xD
