Step 1: Remove the SIM Tray
Start by ejecting and removing the SIM tray from the Samsung Galaxy S20 Ultra 5G.

Step 2: Soften the Back Cover Adhesive
Gently apply heat around the edges of the back cover to soften the factory adhesive.
We are using a heating pad for this process. Place the back-cover side of the phone onto the heating pad, select the Mobile Heating option, and allow the cycle to complete.
Alternatively, you may use a heat gun or hair dryer.

Step 3: Open the Back Cover
Use a suction cup to create a small gap between the frame and the rear glass.
Insert a plastic pry card and carefully slide it around the edges to cut the adhesive.
Once loosened, lift and remove the back cover.

Step 4: Remove the Wireless Charging Pad
Undo the five Phillips screws securing the wireless charging pad.
Disconnect its flex cable and lift the pad out.
Also disconnect the battery connector for safety.

Step 5: Remove the Logic Board Frame
Remove the four screws holding the logic board frame and carefully lift it away from the device.

Step 6: Disconnect and Remove the Front Camera
Disconnect the front camera flex and gently lift the camera module using tweezers.

Step 7: Unlock the Logic Board
Undo the two screws securing the logic board to the frame.

Step 8: Remove the Logic Board
Carefully disconnect six flex connectors from the logic board.
Gently lift the board out using a plastic pry tool.

Step 9: Remove the Rear Camera Assembly
Disconnect the rear multi-camera assembly from the logic board.
There are rear-side and front-side connectors that must be unplugged.

Step 10: Replace Individual Camera Modules
Carefully lift out the depth sensor and ultra-wide camera from the camera frame.
These cameras can be replaced individually if faulty.
The main camera and telephoto camera usually come as a combined unit and must be replaced together if defective.

Install the new camera module(s) into the camera frame.

Step 11: Reinstall the Rear Camera Assembly
Reconnect the rear camera assembly to the logic board by attaching all rear and front-side connectors.

Step 12: Reinstall the Logic Board
Place the logic board back into the phone carefully.
Reconnect all six flex cables firmly.

Step 13: Install the Front Camera
Place the front camera back into position and reconnect its flex cable.

Step 14: Secure the Logic Board
Reinstall the two screws that secure the logic board.
Place the logic board frame back and secure it using four screws.

Step 15: Reconnect the Battery and Wireless Pad
Reconnect the battery flex cable.
Reinstall the wireless charging pad, connect its cable, and secure it with five screws.

Step 16: Prepare the Back Cover
Before sealing the phone, make sure the back cover has sufficient adhesive.
If required, apply B7000 glue or a new double-sided adhesive seal.

Step 17: Close the Device
Align and press the back cover firmly onto the frame.
Use screen clamps or rubber bands to keep pressure on the back cover while the adhesive cures.

Frequently Asked Questions

Q1: Can I replace just the depth or ultra-wide camera on the S20 Ultra 5G?
Yes. The depth and ultra-wide cameras can be replaced individually. The main and telephoto cameras usually come as a combined unit and must be replaced together.

Q2: My camera app shows “Camera Failed” error. Will replacing the camera fix it?
If the error is caused by a faulty camera module, then yes. Ensure the new camera is correctly connected to the logic board before testing.

Q3: Do I need to remove the logic board to replace the cameras?
Yes. The Galaxy S20 Ultra 5G’s rear camera assembly is connected underneath the logic board, so it must be carefully removed to access the cameras.

Q4: Can I reuse the old flex cables when replacing cameras?
It’s not recommended. Flex cables can be fragile and may get damaged during disassembly. Always inspect them and replace if needed.

Q5: Do I need to test the cameras before sealing the back cover?
Absolutely. Power on the device and test all camera modules, front and rear, before installing the back cover. This ensures everything is working properly.

Q6: Can I damage other components during this repair?
Yes. The connectors and ribbon cables on the S20 Ultra 5G are delicate. Use a plastic pry tool and tweezers, apply heat carefully, and proceed slowly to avoid damage.
