Samsung Galaxy Note8 Back Cover Replacement
Swollen batteries can be very dangerous — wear eye protection and exercise caution, or take it to a professional if unsure.
- Do not heat a swollen battery.
- If needed, inject isopropyl alcohol (90+%) around the edges of the back cover to loosen adhesive using a dropper or syringe.
- Opening the phone will damage waterproof sealing.
If you do not replace adhesive seals, your phone will function normally but lose water-protection. Replacement adhesive may be needed for reattachment.
Step 1 | Back Cover
Turn off your device.
- Prepare an iOpener to heat and loosen the adhesive.
- Place the heated iOpener on the rear near the power button.
Step 2
Apply suction to back cover, creating a gap for an opening pick.
- Insert opening pick at a lower angle from underneath, starting in the middle of the side.
Careful not to lever the pick too much to avoid breaking the back cover.
Cut adhesive while pulling up with suction handle.- Move opening pick towards bottom corner, leaving it there to prevent resealing.
- Use additional pick at top corner, if necessary.
- If progress is difficult, reheat iOpener and reapply for further assistance.
Step 3
Insert another opening pick at a 45-degree angle near the top-right corner.
- Carefully move it along the top edge, reheating with an iOpener as needed.
- Leave the pick in place to prevent resealing of the adhesive.
Step 4
Rotate the device and begin separating the adhesive at the bottom with another opening pick.
- Position the pick in the bottom right corner, holding it in place to prevent the adhesive from resealing.
Step 5
Do not force the back cover open — risk of damage.
- Verify that adhesive is separated on all sides, then slowly lift the back cover.
- If the back cover resists removal or begins to bend, use an iOpener to soften the adhesive.
- Be cautious of the fingerprint sensor connector while flipping open the back cover. You may need to disconnect it as described in the next step.
Step 6
Disconnect the fingerprint sensor with a pair of tweezers.
The connector may separate from the motherboard during removal.
Step 7
- Remove the back cover.
Before reassembling, clean the phone's glued areas with isopropyl alcohol and a lint-free cloth
Remove any remaining adhesive from the phone for proper reassembly.
