Samsung Galaxy A72 Screen Replacement

Prepare an iOpener by applying it to the back cover for at least two minutes to loosen the adhesive underneath.

• The iOpener can be replaced with a hair dryer, heat gun, or hot plate, but exercise caution to avoid overheating the phone.
• Avoid excessive heat as it may damage the display and internal battery.

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 using strong tape or superglue it in place and allow it to cure before proceeding.

• Lift the back cover with the suction handle to create a small gap between it and the frame.
• If needed, apply more heat to soften the adhesive further, following 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 it in place to prevent resealing.

Insert a second opening pick along the bottom edge of your phone.

• Slide the opening pick towards the bottom left corner to cut the adhesive.
• Leave the opening picks in place to stop the adhesive from resealing.

If adhesive becomes hard to cut, it has likely cooled down.

• Reheat the adhesive with an iOpener for 1-2 minutes.

Remove the loudspeaker assembly.

• Apply new adhesive as needed during reassembly.
• Clean the areas requiring adhesive with isopropyl alcohol (>90%).

Insert the tweezers into the gap between the display connector and the midframe.

• Gently lift the display connector using the tweezers, working from one side.
