Samsung Galaxy Tab S7 Volume Button Repair

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 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.

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.

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.

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.

Apply a [link|https://www.ifixit.com/Guide/iOpener+Instructions/11677|heated iOpener|new_window=true] to the right edge of the device to loosen the adhesive underneath.

Rotate the opening pick around the bottom-right corner of the device.

Leave the opening pick in place to prevent the adhesive from resealing.

Insert a new opening pick into the gap you created.

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.

Apply a [link|https://www.ifixit.com/Guide/iOpener+Instructions/11677|heated iOpener|new_window=true] to the top edge of the device to loosen the adhesive underneath.

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.

Rotate the opening pick around the top-left corner of the device.

Leave the opening pick in place to prevent the adhesive from resealing.

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.

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.

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 [product|IF145-020|tweezers] or your fingers. Use some high concentration (over 90%) isopropyl alcohol to wipe away any adhesive residue.

If you're using custom-cut adhesives, [guide|124003|follow this guide|new_window=true]. If you're using double-sided tape, [guide|113604|follow this guide.|new_window=true]

Use the flat end of a spudger to pry up and disconnect the display cable's press connector secured to 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.

Use tweezers, or you 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 will need to bend it in the same way when connecting a new screen.

Remove the screen from the frame.

Use the flat end of a spudger to pry up and disconnect the fingerprint scanner cable's press connector.

The fingerprint sensor cable is secured to the screen by adhesive; use heat to avoid tearing the cable during the removal procedure.

Apply a heated iOpener to the bottom edge of the screen for two minutes.

A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the device.

Insert an opening pick between the fingerprint cable's press connector and the circuit board near the bottom of the screen.

Slice the adhesive while prying up with the pick to separate the press connector from the screen.

Slice with an opening pick along the bottom of the fingerprint sensor's cable to separate it from the screen.

Use [product|IF145-020|tweezers], or your fingers, to remove the fingerprint sensor cable.

Set the cable aside. You'll reuse it during reassembly.

You're now left with the screen.

To ensure that your optical fingerprint sensor is secure and accurate, perform a fingerprint sensor calibration after you've reassembled the device:

You'll need the calibration toolkit, which includes three rubber calibration blocks.
