Introduction

This procedure is meant to be used in conjunction with the Galaxy S7 Edge display assembly replacement guide.

What you need

Step 1

              Display Adhesive

Remove all traces of adhesive and debris from the phone frame’s perimeter. Clean the adhesion surface with high concentration isopropyl alcohol (over 90%) and wipe it clean with a lint-free cloth.
If glue or glass remnants are left behind, the new display will not mount correctly and may be damaged.
Do not remove the recessed strip of adhesive trapped under the fingerprint sensor cable. If there is adhesive adhered on top of this strip, carefully separate and peel the top adhesive off.
The capacitative buttons are thin and fragile. If the adhesive surrounding the buttons are in good condition, do not remove them.
If you do plan to replace the button adhesive, use tweezers to carefully pull the adhesive off. If needed, use an opening tool to gently scrape the adhesive off.
Lay the adhesive strips out to get an idea of where they go.
