Samsung Galaxy A72 Back Cover Replacement
Failing to replace adhesive seals during reassembly may compromise water resistance.
- Follow this guide to replace a damaged back cover.
- Purchase replacement adhesive for secure reassembly.
Step 1 | Heat the back cover
Prepare an iOpener by applying it to the back cover for at least two minutes.
- This will loosen the adhesive underneath.
Use a hair dryer, heat gun, or hot plate with caution: overheating can damage the display and internal battery.
Step 2 | Insert an opening pick
Secure a suction handle to the back cover's bottom edge, as close to the edge as possible.
If the back cover is cracked, the suction handle may not stick: try lifting it with strong tape or superglue the suction handle in place and let it cure.
- Lift the back cover with the suction handle to create a small gap between the cover and frame.
- In case of trouble, apply more heat to soften the adhesive further; follow iOpener instructions to avoid overheating.
- Insert an opening pick into the created gap.
- Slide the opening pick to the bottom right corner to slice the adhesive.
- Leave the opening pick in place to prevent the adhesive from resealing.
Step 3 | Slice the adhesive
- Place a second opening pick at the bottom edge of the phone.
- Slide the new pick towards the bottom left corner to separate the adhesive.
Do not remove the opening picks as this can cause the adhesive to reseal.
Step 4 | Slice the adhesive
If the adhesive becomes hard to cut, it has likely cooled down.
- Reheat the adhesive using an iOpener for one to two minutes.
- Insert a third opening pick at the bottom left corner of your phone.
- Slide the opening pick along the left edge to slice the adhesive.
Leave the opening pick in the top left corner to prevent resealing.
Step 5
Insert a fourth opening pick under the top left corner.
- Slide the opening pick along the top edge to slice the adhesive.
- Leave it in the top right corner to prevent resealing.
Step 6
- Position a fifth opening pick under the top right corner.
- Slide it along the right edge to cut through any remaining adhesive.
Step 7 | Remove the back cover
Remove the back cover.
- Clean the relevant areas with isopropyl alcohol (>90%).
- Apply new adhesive where necessary.
- Secure the back cover using pre-cut adhesive or double-sided adhesive tape.
Apply strong, steady pressure to your phone for several minutes after installing the back cover to ensure a good bond. A stack of heavy books can help.
