Samsung Galaxy S7 Edge Loudspeaker Assembly Replacement
Adhesive on the Samsung Galaxy S7 Edge is extremely stubborn; repeated heat and pull cycles are required to loosen it.
- Start by carefully following this repair guide for loudspeaker assembly replacement.
- Apply patience, as multiple heat and pull cycles will be necessary to fully remove the adhesive.
Step 1 | Rear Glass
Opening your phone will compromise its waterproof seals; replacement adhesive is recommended.
- Prepare replacement adhesive before proceeding or take precautions against liquid exposure upon reassembly.
- Heat an iOpener for two minutes on a long edge of the phone.
- Reheat and reapply as needed, following iOpener instructions to avoid overheating.
- Alternatively, use a hair dryer, heat gun, or hot plate with caution: the OLED display and internal battery are susceptible to heat damage.
Step 2
Phone back cover must be removed with caution as curved glass can cause suction cup failure.
- Apply a suction cup near heated edge of phone, avoiding the curve.
- If cracked or stubborn back cover: use strong tape or superglue for suction cup adhesion.
Insert opening pick under rear glass while lifting on suction cup. Be prepared to push up due to curved design.
- Reapply heat as needed to soften adhesive, which cools rapidly.
Step 3
Reheat the iOpener and reapply it to soften the adhesive.
- Ensure the pick remains firmly inserted into the glass.
Step 4
Slide opening pick along phone side, separating adhesive.
Go slowly to avoid losing tip in seam.
- If sliding becomes difficult, reheat and reapply iOpener.
- Leave first pick in place and grab a second for next step.
- Leaving first pick inserted helps prevent re-adhesion of separated glue.
Step 5
- Repeat the heating and cutting process for the remaining three sides.
- Apply an opening pick to each side before moving on to the next, preventing the adhesive from resealing.
Step 6
Remove the display by lifting the glass.
- Lift the display carefully.
- Disconnect any cables attached to the display.
Step 7
Remove remaining adhesive residue from phone chassis with tweezers.
- Clean adhesion areas with high concentration (at least 90%) isopropyl alcohol and a lint-free cloth.
- Peel adhesive backing off new rear glass, then align one edge against the phone chassis.
Ensure phone powers on and functions correctly before installing new adhesive.
- If reusing old back cover or a non-adhesive model, consult separate guide.
- To reinstall without replacing adhesive, remove large debris chunks from back cover.
Note: Back cover will not be waterproof if not replaced with adhesive, but glue is usually sufficient for holding in place.
Step 8 | Loudspeaker Assembly
Remove all twelve Phillips screws, 3.5 mm in size.
Step 9
Locate the small notch on the lower left corner of the upper antenna.
- Pry the upper antenna out from this notch using a suitable tool.
- Once loose, carefully remove the upper antenna from the phone.
Step 10
Remove the wireless charging coil from the phone.
Step 11
Remove the loudspeaker from the phone.
