Samsung Galaxy S7 Microphone Replacement
The Galaxy S7 microphone issue can be solved without needing to remove the LCD display.
Step 1 | Rear Glass
Opening your phone will compromise its waterproof seals.
- Have replacement adhesive ready before proceeding, or take care to avoid liquid exposure during reassembly if not replacing adhesive.
- Apply a heated iOpener to a long edge of the phone for about two minutes.
- Reheat and reapply as needed until phone is warm enough, following iOpener instructions to avoid overheating.
- Alternatively, use a hair dryer, heat gun, or hot plate with caution: be careful not to overheat the OLED display and internal battery.
Step 2
Apply suction cup near heated edge of phone, avoiding curved section.
- Heat until back panel feels warm to touch before applying suction cup.
Suction may not stick if back cover is cracked; use strong tape or superglue for better adhesion.
- Lift phone with suction cup and insert opening pick under rear glass.
Use caution: excessive force can cause rear glass to break, especially when pushing up on curved section.
- If necessary, reapply heat to soften adhesive for better access.
- Optionally, add a few drops of isopropyl alcohol to weaken adhesive further.
Step 3
Reheat and reapply iOpener to soften adhesive.
- Firmly insert pick into glass.
Step 4
Slide a pick down the side of the phone, carefully separating adhesive.
Go slowly to avoid losing contact with the seam.
- If sliding becomes difficult, reheat and reapply the iOpener.
- Leave the pick in place while grabbing a second pick for the next step.
Step 5
Continue heating and cutting, repeating the process for all four sides.
Make sure to leave a pick inserted into each side before moving on.
Step 6
Remove the glass screen by lifting it up.
- Locate the glass screen clips on the phone.
- Gently pry the glass screen away from its clips.
- Lift the glass screen out of the phone.
Step 7
Ensure phone is powered on and test functionality after repair.
- Clean midframe surface with isopropyl alcohol; avoid contact with wireless charging coil as this will damage its coating.
- Reinstall back cover using custom-cut adhesive strip, or remove old adhesive to ensure a flush fit and then apply glue for securement.
Note that glued-only installation may compromise waterproofing.
