Need help removing the back cover

Hey there! I just replaced a Galaxy S7 rear camera lens for a customer. I didn't have to remove the whole back glass. I just used my heat gun to heat up the camera lense, took a sharp plastic pry tool and gently poked through the middle of the lense without touching the actual camera. I worked the lense up all the way around until it came off as a whole. Cleaned the remaining adhesive off with some alcohol and pry tool.

If you're wanting to open the whole back glass of the S7, a heat gun(good hair dryer), some decent plastic pry tools, and some playing cards help. Don't cook it but get it hot to the touch. Gently pry around the edges of the back glass all the way around the phone. Use a playing card to break the adhesive bond but sticking it between the glass and mid frame and sliding it along. Hope this helps!!
