Introduction

Use this guide to remove or replace the wireless charging coil on your Samsung Galaxy Note20.

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. Completely power off your phone before you begin disassembly.
    • 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, internal battery, and the plastic rear cover are susceptible to heat damage.

  2. Apply a suction cup to the heated edge of the rear cover, as close to the edge as possible. 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. As you cut through the adhesive around the perimeter of the phone, don't insert the pick more than 5 mm to avoid damaging internal components. 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.

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

  4. 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.

    • 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.

    • If the rear cover is still attached to the frame after cutting through all four sides, try slicing through the adhesive again with an opening pick.

  5. Lift the rear cover straight up to remove it. Lift the rear cover straight up to remove it.

    • 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.

  6. Use a pair of tweezers to lift up and flip back the motherboard shield. Be careful when handling the motherboard shield because its edges are thin and sharp. Be careful when handling the motherboard shield because its edges are thin and sharp.

    • 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.
