Galaxy S20 Wireless Charging Coil Replacement

Unplug your phone from power source.

Heat an iOpener for 2 minutes and apply it to the back cover's bottom edge.

• Use a hair dryer, heat gun, or hot plate as alternative heating methods.
• Be cautious not to overheat the phone, as the display and internal battery are vulnerable to heat damage.

Apply a suction cup to the phone's back, near its center.

• If your screen is severely cracked, cover it with clear packing tape for better adhesion.
• Alternatively, use strong tape or superglue the suction cup to the broken screen as a last resort.

Apply firm, steady pressure on the suction cup to create a gap between the back cover and frame.

• Insert an opening pick into the gap, taking care not to apply excessive force that may crack the glass.

Multiple attempts using the iOpener and suction cup may be necessary due to tight tolerances.

• If you're having trouble creating a gap, reapply heat to the edge and try again.

Risk of cracked glass if cutting near curved edges.

• Slide pick back and forth along bottom edge to slice through adhesive.
• Avoid cutting near phone corners, as it may damage the curved glass panel.
• Leave pick in seam after completion to prevent resealing of adhesive.

Apply a iOpener to the left edge of the back cover and heat it for 2 minutes.

Apply a suction cup near the left edge of the phone's back.

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

Do not apply excessive force or risk cracking the glass.

Insert an opening pick into the gap, as far as possible under the curved edge of the glass.

• If unsuccessful, try applying more heat to the edge and attempting again.

Tight tolerances may require multiple attempts.

Alternatively, apply a few drops of high concentration isopropyl alcohol into the seam to loosen the adhesive.

Insert the pick deeper under the glass's edge, then tilt it downwards.

• The goal is to fully separate the back cover's adhesive from the device's body.

Be cautious when sliding across the ridge around the volume and power buttons — risk of damaging the cutout in the glass.

• Slide a pick along the left edge of the phone to separate the back cover's adhesive.
• Leave the pick under the left edge of the glass near the top left corner to prevent resealing.

Apply a iOpener to the right edge of the back cover for 2 minutes.

• A hair dryer, heat gun, or hot plate can also be used, but avoid overheating the phone.

The display and internal battery are susceptible to heat damage.

Apply a suction cup to the phone's back, as close to the right edge center as possible.

• Pull on the suction cup with strong, steady force to create a gap between the back cover and frame.
• Insert an opening pick into the gap.
• Tilt the pick downward to fully insert it underneath the back cover.

Slide a pick along the right edge of the phone to separate the back cover's adhesive.

Leave one pick under the right edge of the glass, near the top, to prevent resealing.

• The back cover may release other picks; set them aside if this occurs.
• The bottom edge should not reseal from this point onward.

Use a iOpener to apply heat to the top edge of the back cover for 2 minutes.

Be gentle when handling the back cover due to curved glass near corners.

• Slide a pick from the right edge along the top right corner.
• Continue cutting along the top edge to the top left corner, separating adhesive completely.

If cutting becomes difficult, stop and reapply heat before continuing.

Slowly lift the back cover using care.

• Use opening picks to cut any remaining adhesive.
• Remove the back cover.

Power on your phone and test all functions before sealing. Never skip this step — risk of incomplete assembly.

• Disconnect power completely by shutting down your phone.
• Remove any adhesive chunks using tweezers or your fingers.
• Apply heat if needed to separate the adhesive.

If custom-cut adhesives are used, follow this specific guide for proper application and sealing.

• If double-sided tape is being used, refer to this guide for best practices during reassembly.

Use a Phillips #00 screwdriver to remove the five 4mm-long screws securing the motherboard bracket.

• Keep track of each removed screw and ensure it goes back to its original location.

Use tweezers to carefully lift and unclip the motherboard bracket from the plastic midframe.

Do not remove the bracket completely yet, as it is still attached to the wireless charging coil.

Remove the wireless charging coil by gently peeling it away from the device.

• No connectors need to be disconnected as the wireless charging coil is connected via spring contacts.

When reassembling, refasten the motherboard bracket screws first to prevent damage during alignment of the charging coil. Then firmly press the rest of the coil into place.
