Introduction

Use this guide to replace the USB-C port and daughterboard in your Samsung Galaxy Tab S7+ 5G.

In order to replace the USB-C port and daughterboard, you must remove the screen. The screen has sensitive components, so there's a risk you'll damage it during the procedure. Be sure to apply plenty of heat and be extremely careful during the prying stage.

Before you begin, refer to the Samsung Self-Repair document for safety information.

For your safety, fully discharge the battery 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.

Note: Retaining water resistance after the repair will depend on how well you reapply the adhesive, but your device will lose its IP (Ingress Protection) rating.

Some photos in this guide are from a different model and may contain slight visual discrepancies, but they won't affect the guide procedure.

  1. Samsung Galaxy Tab S7+ 5G USB-C Charging Port and Daughterboard Replacement, Heat the bottom edge: step 1, image 1 of 1
    • Completely power off your device before you begin.

    • Apply a heated iOpener 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.

    • 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.

  3.

    • 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.

Samsung Galaxy Tab S7+ 5G USB-C Charging Port and Daughterboard Replacement, Remove the screen: step 15, image 1 of 3 Samsung Galaxy Tab S7+ 5G USB-C Charging Port and Daughterboard Replacement, Remove the screen: step 15, image 2 of 3 Samsung Galaxy Tab S7+ 5G USB-C Charging Port and Daughterboard Replacement, Remove the screen: step 15, image 3 of 3
    • 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, lift the bottom edge of 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.

  16. Samsung Galaxy Tab S7+ 5G USB-C Charging Port and Daughterboard Replacement, Disconnect the display cable: step 16, image 1 of 2 Samsung Galaxy Tab S7+ 5G USB-C Charging Port and Daughterboard Replacement, Disconnect the display cable: step 16, image 2 of 2
    • Use the flat end of a spudger to pry up and disconnect the display cable's press connector secured to the screen.

    • Be careful not to damage the wide display flex ribbons on the bottom edge of the screen.

    • To re-attach press connectors 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 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

    • Remove the daughterboard from the frame.

    • During reassembly, reconnect the interconnect cable to the daughterboard before fastening the screws.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.

To reassemble your device, follow the instructions in reverse order and perform the opposite actions, e.g., "reattach" instead of "removing." Skip steps that use heating and prying, and pay close attention to the 📌 bullets as you work through the steps.

After you've completed the repair, download the Samsung Members App from the Galaxy Store or the Play Store, and follow the Samsung Self-Repair document (beginning page 9) to make sure your device is fully functional.
