How to Find Tools and Parts
👉 How to Use the Heating Pad Properly
Turn off the Galaxy S20 Ultra completely. Eject and remove the SIM tray to prevent accidental damage during the repair.
The back cover is secured with adhesive. Place the phone’s back side on a heating pad and select the mobile phone heating option. Alternatively, use a heat gun or hair dryer. Apply gentle, even heat around the edges until the adhesive softens.
Use a suction cup to create a small gap, then slide a plastic pry tool or card around the edges to separate the back cover. Lift the cover carefully.
Unscrew and disconnect the wireless charging pad from the connectors. Lift it out carefully.
Locate the bottom speaker cover. Unscrew the screws holding it in place and remove the cover to access the charging port board and vibrator motor.
Undo the screws securing the charging port board and disconnect its connectors. Carefully lift the board out of the device.
In This Step, Replace the Charging Port Board if the Phone Is Not Charging
The vibrator motor sits next to the charging port board. Apply slight heat if needed, then carefully lift out the non-working motor using a plastic pry tool or tweezers.
Place the new vibrator motor in the exact location of the old one. Ensure it sits securely and is properly aligned with the connector.
Place the charging port board back into position. Reconnect all flex cables and secure the board with its screws.
Place the speaker cover back over the bottom components and secure it with screws.
Position the wireless charging pad, reconnect its flex cable, and secure it with screws.
Before reinstalling the back cover, check that the adhesive is sufficient. If it is weak, apply B7000 glue or a new double-sided back cover adhesive.
Press the back cover firmly into place. Use screen binding clips or rubber bands to hold the cover until the adhesive sets.
Power on your Galaxy S20 Ultra and test both the vibrator motor and charging functionality to ensure everything works correctly.
