Apply a heated iOpener to a long edge of the phone for about two minutes.
-
-
-
When the back panel is warm to the touch, apply a suction cup as close to the heated edge of the phone as you can while avoiding the curved edge.
-
Lift on the suction cup and insert an opening pick under the rear glass.
-
-
-
Once you have the pick firmly inserted into the glass, reheat and reapply the iOpener to soften the adhesive.
-
-
-
-
Slide the opening pick down along the side of the phone, separating the adhesive.
-
Leave the pick in place and grab a second pick as you proceed to the next step. Leaving the pick inserted can help prevent the glue you just separated from re-adhering.
-
-
-
Repeat the previous heating and cutting procedure for the remaining three sides of the phone.
-
Leave an opening pick in each edge of the phone as you continue to the next to prevent the adhesive from resealing.
-
-
-
Lift the glass and remove it from the phone.

If you're cleaning the midframe surface with isopropyl alcohol, be careful not to get any alcohol on the wireless charging coil. The coil coating will break down if it contacts alcohol.

They don’t tell you this, but be careful with the picks when you are trying to separate the back cover from the chassis. It’s very easy for the pick to get between the backplate, which is really clear plastic, and the foil-ish lining that makes it look like sleek black glass- I’m sure the heat doesn’t help keep the foil laminated to the backplate. Then your only option will be to replace the entire backplate, or remove the foil-ish lining and let the back of your phone be au natural.
When I removed the back cover, I found the adhesive had stayed adhered to the phone and separated from the back cover. This actually made it easier to remove cleanly with the forceps.
Should you not replace the adhesive tape? If so, what type/brand/size should one use? Would this be appropriate? 4mm 3M red Strong Sticky Glue Tape for Samsung (https://www.amazon.com/gp/product/B07P1J...) ?
Hi Bryan!
You should definitely replace the adhesive. You can use some custom-cut adhesive made specifically for the S7, or you can use double-sided tape like Tesa tape. For this situation, the precut card would be more than enough.
This one's a challenge with cracked glass, but it is doable if you go up to the crack and start working on other areas and meet it. Lift on both sides - carefully and with a constant, even pressure - and you'll be able to work around the glue.
I had to use 5 picks at most to fight the cracks, but once you get an entire side up it's easy work.
