Samsung Galaxy Z Fold8 Ultra Rear Camera Replacement
This repair guide explains how to replace the rear camera module on your Samsung Galaxy Z Fold8 Ultra when you experience issues such as unfocused shots, physical sensor damage, camera app failure, or persistent optical image stabilization vibrating. Because this foldable phone utilizes an ultra-thin frame, high-density component layout, and dual-cell battery architecture, disassembly demands absolute patience and gentle handling. Following this procedure will allow you to safely disassemble the rear chassis, detach the midframe shielding, and swap the multi-lens camera module.
Required Tools
- Heat gun or specialized electronics heating pad
- Suction cup handle
- Thin plastic opening picks
- Phillips #00 precision screwdriver
- ESD-safe angled tweezers
- Non-conductive nylon spudger
- High-percentage isopropyl alcohol (90% or higher) and lint-free wipes
- Hand air blower (dust-free)
- Precut rear glass replacement adhesive
- ESD grounding wrist strap or anti-static mat
Step by step
- 1
Step 1: Shut Down and Discharge the Phone
Power off the Galaxy Z Fold8 Ultra completely and ensure the dual battery charge is below 25 percent to prevent thermal runaway if accidentally punctured.
Fold the device shut and place it face down on an anti-static work mat.

Step 2: Heat the Rear Glass Assembly
Apply heat evenly around the perimeter edges of the back panel with a heat pad or heat gun set to 75–80 °C for about three to five minutes.
The heat softens the factory water-resistant adhesive without endangering the internal lithium-ion cells or displays.

Step 3: Slice Through the Perimeter Adhesive
Fasten a heavy-duty suction handle near the lower edge of the back panel and gently pull upward to create a hairline separation.
Insert a thin plastic pick into this opening and carefully slide it around the perimeter, never inserting it more than 3 millimeters deep near the camera island to avoid tearing internal flex ribbons.

Step 4: Remove the Back Glass Cover
Slowly lift the back cover off the midframe once all border adhesive has been separated.
Set the panel aside in a safe spot, and clean off any fragmented adhesive along the phone frame using a lint-free swab dipped in isopropyl alcohol.

Step 5: Detach the Motherboard Shield and Wireless Coil
Use a Phillips #00 screwdriver to remove all securing screws from the top internal shield and integrated wireless charging coil.
Carefully pry up the plastic retainers with a nylon spudger and lift the bracket clear to reveal the logic board.

Step 6: Disconnect Both Battery Cables
Identify both battery ribbon connectors attached to the mainboard.
Disconnect them using a plastic spudger before touching any other electronics; prying these off first ensures the circuit is dead and prevents short-circuit damage.

Step 7: Disconnect the Rear Camera Connectors
Locate the modular press-fit connectors belonging to the rear camera assembly.
Using the edge of your plastic spudger, carefully pry each connector straight up off its mating socket on the logic board.

Step 8: Extract the Faulty Camera Array
Carefully leverage the camera module out of its fitted metal recess using blunt ESD tweezers or a spudger.
Apply force solely to the outer metal bracket of the camera array to avoid cracking the underlying logic board.

Step 9: Install the Replacement Camera Module
Use a handheld air blower to clear any dust specks from the inner chassis camera lenses.
Seat the replacement multi-camera module into the housing recess and press the ribbon connectors down until they click firmly onto the motherboard sockets.
- 10
Step 10: Reconnect Power and Test Camera Features
Snap both battery connectors back into their sockets, rest the wireless coil on top, and turn on the device.
Launch the camera app to verify autofocus, zoom transitions across all sensors, and optical stabilization before finalizing the repair.
- 11
Step 11: Reassemble the Internal Midframe
Power down the handset again, replace the protective motherboard bracket, and hand-tighten the Phillips screws evenly.
Ensure no flex cables are pinched beneath the shielding during reinstallation.
- 12
Step 12: Apply New Adhesive and Reseal
Lay down the precut adhesive film cleanly along the outer perimeter of the frame.
Position the back glass back onto the chassis, press firmly along all edges, and maintain mild clamping pressure for 15 to 20 minutes to secure the bond.

Frequently asked questions
No, the rear camera sensors on the Fold8 Ultra are engineered as a consolidated, precision-aligned module. Replacing the complete assembly ensures that optical alignment, sensor calibrations, and multi-lens transitions work without error.
Avoid touching any exposed lens elements with your bare hands, avoid compressed aerosol cans that can spray liquid propellant, and peel the protective lens films only a few seconds before lowering the module into place.
Opening the device ruins the original factory seal. While applying high-grade precut adhesive restores moderate dust and splash protection, the original IP water resistance rating cannot be fully guaranteed after DIY disassembly.
Disconnect both batteries, confirm that each camera ribbon connector is aligned and fully seated into its socket, and restart the device. If the issue persists, clear the camera app storage cache in system settings.
