Use this guide to remove or replace the USB-C port on your Samsung Galaxy Note20 Ultra.

For your safety, discharge the battery below 25% before disassembling your phone. This reduces the risk of a dangerous thermal event if the battery is accidentally damaged during the repair. If your battery is swollen, take appropriate precautions.

  1. Samsung Galaxy Note20 Ultra USB-C Port Replacement, Heat the rear cover: 手順 1、 1の画像 1
    • Completely power off your phone before you begin disassembly.

    • Heat an iOpener and apply it to the left side of the rear cover for one minute.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the screen and internal battery are susceptible to heat damage.

  2. Samsung Galaxy Note20 Ultra USB-C Port Replacement, Insert an opening pick: 手順 2、 3の画像 1 Samsung Galaxy Note20 Ultra USB-C Port Replacement, Insert an opening pick: 手順 2、 3の画像 2 Samsung Galaxy Note20 Ultra USB-C Port Replacement, Insert an opening pick: 手順 2、 3の画像 3
    • Apply a suction cup to the heated edge of the rear cover, as close to the edge as possible.

    • If your back glass 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 cup. If all else fails, you can superglue the suction cup to the broken panel.

    • Pull up on the suction cup with strong, steady force to create a gap between the rear cover and the frame.

    • Depending on the age of your phone, this may be difficult. If you are having trouble, apply more heat to the edge and try again.

    • Insert an opening pick into the gap.

    • Don't insert the opening pick more than 5 mm into the phone or you risk damaging the internal components.

  3. Samsung Galaxy Note20 Ultra USB-C Port Replacement, Begin to cut the adhesive: 手順 3、 3の画像 1 Samsung Galaxy Note20 Ultra USB-C Port Replacement, Begin to cut the adhesive: 手順 3、 3の画像 2 Samsung Galaxy Note20 Ultra USB-C Port Replacement, Begin to cut the adhesive: 手順 3、 3の画像 3
    • Slide the opening pick along the left edge towards the bottom left corner to cut through the adhesive.

    • Leave the pick inserted in the bottom left corner to prevent the adhesive from re-sealing.

  4. Samsung Galaxy Note20 Ultra USB-C Port Replacement, Cut along the perimeter of the rear cover: 手順 4、 3の画像 1 Samsung Galaxy Note20 Ultra USB-C Port Replacement, Cut along the perimeter of the rear cover: 手順 4、 3の画像 2 Samsung Galaxy Note20 Ultra USB-C Port Replacement, Cut along the perimeter of the rear cover: 手順 4、 3の画像 3
    • While cutting through the adhesive, don't insert the opening pick more than 5 mm into the phone or you risk damaging the internal components.

    • Repeat the process of heating and cutting the adhesive along the three remaining sides of the rear cover.

    • You can insert each new opening pick in the gaps created by the opening picks left in each corner.

    • As you proceed, leave an opening pick in each corner to prevent the adhesive from re-sealing.

    • Slide an opening pick back and forth around the entire perimeter of the phone to release any missed adhesive. Reheat any stubborn adhesive.

  5. Samsung Galaxy Note20 Ultra USB-C Port Replacement, Remove the rear cover: 手順 5、 2の画像 1 Samsung Galaxy Note20 Ultra USB-C Port Replacement, Remove the rear cover: 手順 5、 2の画像 2

  6. Samsung Galaxy Note20 Ultra USB-C Port Replacement, Disconnect the wireless charging coil: 手順 6、 2の画像 1 Samsung Galaxy Note20 Ultra USB-C Port Replacement, Disconnect the wireless charging coil: 手順 6、 2の画像 2
    • Use the pointed end of a spudger to pry up and disconnect the wireless charging coil press connector.

    • Take care to pry only under the edge of the connector to prevent damaging the socket itself and surrounding components.

    • 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.

  7. Samsung Galaxy Note20 Ultra USB-C Port Replacement, Disconnect the white press connector: 手順 7、 2の画像 1 Samsung Galaxy Note20 Ultra USB-C Port Replacement, Disconnect the white press connector: 手順 7、 2の画像 2
    • Use the pointed end of a spudger to pry up and disconnect the white press connector located in the bottom right of the motherboard shield.

    • Use a Phillips screwdriver to remove the six 4.0 mm screws securing the motherboard shield.

    • If these screws have not been removed before, they may be difficult to remove as they have threadlocker on their threads.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.

I would like to also add to this tutorial for the last step after you remove the USB-C Charging port and once you reinstall the port, rather its a new one or the same stock oem port that you took out. You should be extremely cautious to how tight you tighten these screws as the LED Touch Display actually lays flat against the frame and if you over tighten these screws that hold this port down, you will figure out quite easily that 1. the screens are very fragile and 2. these screws are able to be tightened and will not stop causing unwanted pressure onto the screen and will destroy the screen which will make it useless as the phone will work just without a display or touch interactions with the phone until buying a new display to replace it.

Big rule of thumb for smartphones, tighten only until it feels snug, don't crank things as tightly as they can go. This was also a problem for iPhone repair, some were cranking as tight as possible and killing their screens. The screws have loctite, they're not going anywhere.
