Samsung Galaxy Note20 Rear Cover Replacement
Discharge the battery to below 25% to prevent damage and thermal risks, especially for swollen batteries.
- Samsung Galaxy Note20 rear cover removal requires this guide.
- Prepare your phone by discharging the battery to at least 25% or less before proceeding with disassembly.
- Take extra precautions if your battery is swollen.
Step 1 | Heat the rear cover
Power off your phone completely before starting disassembly.
Be cautious when using heat to loosen the rear cover: overheating can damage the screen, internal battery, or plastic components.
- Apply an iOpener to the left side of the rear cover for one minute to loosen it.
- Alternatively, use a hair dryer, heat gun, or hot plate, but monitor temperature and avoid overheating.
Step 2 | Insert an opening pick
Apply a suction cup to the heated edge of the rear cover, as close to the edge as possible.
- Pull up on the suction cup with strong, steady force to create a gap between the rear cover and the frame.
- If having trouble, apply more heat and try again — difficulty may vary depending on phone age.
Insert an opening pick into the gap no deeper than 5 mm to avoid damaging internal components.
Step 3 | Begin to cut the adhesive
Insert the opening pick no more than 5 mm deep to avoid damaging internal components.
- Slide the opening pick along the left edge towards the bottom left corner to cut through the adhesive.
- Leave the pick inserted in the bottom left corner to prevent re-sealing of the adhesive.
Step 4 | Cut along the perimeter of the rear cover
Insert a new opening pick into the gaps created by existing picks in each corner.
- Heat and cut along the next side of the rear cover.
- Repeat this process for the remaining two sides.
If the rear cover is still attached, re-slice the adhesive with an opening pick.
Step 5 | Remove the rear cover
Remove the rear cover by lifting it straight up.
