Step-by-Step Process
Step 1: Heat the bottom edge
Completely power off your device before you begin.
Apply a [link|https://www.ifixit.com/Guide/iOpener+Instructions/11677|heated iOpener|new_window=true] to the bottom edge of the device for three minutes 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 a damaged 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 4: Separate the bottom adhesive
Insert a new opening pick into the gap you created.
Slide the new pick along the bottom edge of the device towards the bottom-right corner.
Step 5: Heat the right edge
Apply a [link|https://www.ifixit.com/Guide/iOpener+Instructions/11677|heated iOpener|new_window=true] to the right edge of the device for two minutes to loosen the adhesive underneath.
Step 6: Separate the bottom-right corner adhesive
Rotate the opening pick around the bottom-right corner of the device.
Leave the opening pick in place to prevent the adhesive from resealing.
Step 7: Separate the right edge
Insert a new opening pick into the gap you created at the bottom right corner.
Don't insert the pick more than 3 mm to avoid damaging the components along the right edge.
Slide the new pick along the right edge of the device towards the top-right corner.
Step 8: Heat the top edge
Apply a [link|https://www.ifixit.com/Guide/iOpener+Instructions/11677|heated iOpener|new_window=true] to the top edge of the device for two minutes to loosen the adhesive underneath.
Step 9: Separate the top-right corner adhesive
Rotate the opening pick around the top-right corner of the device.
Leave the opening pick in place to prevent the adhesive from resealing.
Step 10: Separate the top adhesive
Insert a new opening pick into the gap you created.
Slide the new pick along the top edge of the device towards the top-left corner.
Step 11: Heat the left edge
Apply a [link|https://www.ifixit.com/Guide/iOpener+Instructions/11677|heated iOpener|new_window=true] to the left edge of the device to loosen the adhesive underneath.
Step 12: Separate the top-left corner adhesive
Rotate the opening pick around the top-left corner of the device.
Leave the opening pick in place to prevent the adhesive from resealing.
Step 13: Separate the left adhesive
Insert a new opening pick into the gap you created.
Slide the new pick along the left edge of the device towards the bottom-left corner.
Step 14: Separate the bottom-left corner adhesive
Rotate the opening pick around the bottom-left corner of the device.
Leave the opening pick in place to prevent the adhesive from resealing.
At this point, the perimeter of the screen should be separated from the frame. If there's still resistance around the edges of the screen, use an opening pick to cut the adhesive again.
Step 15: Remove the screen
Don't try to remove the screen all the way yet; it's still connected by a flex cable.
With the top of the device facing you, lift the bottom edge of the screen up and away from you like you're opening a book.
Rest the screen upside down before continuing.
Be careful not to strain 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 [product|IF145-020|tweezers] or your fingers. Use some high concentration (over 90%) isopropyl alcohol to wipe away any adhesive residue.

Step 16: Disconnect the display cable
Use the flat end of a spudger to pry up and disconnect the display cable's press connector from the back of the screen.
Be careful not to damage the wide display flex ribbons on the bottom edge of the screen.
To re-attach [https://www.ifixit.com/Guide/Recognizing+&+Disconnecting+Cable+Connectors/25629#s70308|press connectors|new_window=true] like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.
Step 17:
Use tweezers, or your fingers, to hold the display cable in place.
Use the flat end of a spudger to pry up and disconnect the fingerprint sensor's press connector attached to the display cable.
Take note of the display cable's position—you'll need to bend it in the same way when connecting a new screen.
Step 18: Remove the screen
Remove the screen from the frame.
Step 19: Unfasten the frame bracket
Use a Phillips #00 screwdriver to remove the fifty 3 mm-long screws securing the frame bracket to the frame.
The third photo has the same screws marked by quadrant. Use this photo during reassembly to help account for all the screws:
Bottom-left = 9 screws
Bottom-right = 14 screws
Top-right = 12 screws
Top-left = 15 screws
Step 20: Remove the frame bracket
Lift the frame bracket away from the frame, making sure to thread the display cable through its socket.
Step 21: Disconnect the battery
Use the flat end of a spudger to pry up and disconnect the battery's press connector secured to the motherboard.
Step 22: Disconnect the antenna board's interconnect cable
Use the flat end of a spudger to pry up and disconnect the antenna board interconnect cable's press connector secured to the antenna board.
Step 23: Unfasten the antenna board
Use a Phillips #00 screwdriver to remove the 2 mm-long screw securing the antenna board to the frame.
Step 24: Remove the antenna board
Insert a spudger into a gap between the antenna board and the frame.
Pry up with the spudger to separate the antenna board from the frame.
Remove the antenna board.
