Introduction
For your safety, discharge the battery below 25% before disassembling your tablet. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.
There is a significant chance that you may break the unreinforced and fragile display panel during this procedure. Be sure to apply plenty of heat and be extremely careful during the prying stage.
You’ll need replacement adhesive in order to complete this repair.
What you need
Step 1
Heat the bottom edge
- Completely power off your device before you begin.
- Apply a heated iOpener to the bottom edge of the device to loosen the adhesive underneath.
- The display adhesive of the Galaxy Tab S7+ is extremely strong, and it’s likely you need to reheat and reapply the iOpener several times before starting the display removal and during the removal procedure.
- A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the device.

Step 2
Screen removal information
- While you’re waiting for the adhesive to loosen, note the following:
- There’s a long circuit board attached to the screen that sits parallel to the bottom edge.
- Don’t insert the pick more than 2 mm to avoid damaging the circuit board.
- This image shows an example of the display separating from the glass panel.
- Don’t insert the pick more than 3 mm to avoid damaging the display.

This image shows an example of the display separating from the glass panel.
Don’t insert the pick more than 3 mm to avoid damaging the display.
Step 3
Insert an opening pick
- Once the screen is warm to touch, apply a suction handle to the bottom edge of the screen and as close to the edge as possible.
- If your screen is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction handle. If all else fails, you can superglue the suction cup to the screen.
- Lift the screen with the suction handle to create a small gap between the screen and the frame.
- Insert an opening pick into the gap between the frame and the screen.
- Don’t insert the pick more than 2 mm to avoid damaging the circuit board.
- Leave the opening pick in place to prevent the adhesive from resealing.

Step 15
Remove the screen
- Don’t try to remove the screen all the way yet; it’s still connected to the frame by a flex cable.
- With the top of the device facing you, pull the screen up and away from you like you’re opening a book.
- Rest the screen upside down and parallel to the frame before continuing.
- Don’t twist the screen or move it too far away from the frame to avoid damaging the flex cable.
- During reassembly:
- This is a good point to power on your tablet and test all functions before sealing it up. Be sure to power your tablet back down completely before you continue working.
- Remove any adhesive chunks with a pair of tweezers or your fingers. Use some high concentration (over 90%) isopropyl alcohol to wipe away any adhesive residue.
- If you’re using Samsung custom-cut adhesives, follow this guide. If you’re using double-sided tape, follow this guide.

Apply isopropyl alcohol
- Take care not to puncture or bend the battery with your tool—a punctured or bent battery may leak dangerous chemicals or cause a fire. In case you’re struggling to pull up the battery, apply more isopropyl alcohol and try again.
- Apply a few drops of high concentration (over 90%) isopropyl alcohol to the gaps surrounding the battery’s right edge.
- Wait between one to two minutes for the adhesive to loosen.
- Only apply a few drops initially and apply more if necessary; too much isopropyl alcohol might overflow onto the motherboard and daughterboard.

Battery removal information
- While you’re waiting for the adhesive to loosen, note the following:
- The battery is comprised of two cells that are shrouded in a plastic jacket.
- The adhesive securing the battery to the frame is concentrated in a ring shape around the perimeter of the battery.
- To minimize the risk of bending or breaking the cells, it’s recommended you separate the adhesive cell-by-cell before the entire battery is removed.
