Samsung Galaxy Z TriFold Rear Camera Replacement

A camera replacement on the Samsung Galaxy Z TriFold is necessary when you experience persistent autofocus hunting, cracked sensor glass, black screen errors in the camera app, or failed optical image stabilization. Because this tri-folding flagship uses an ultra-thin chassis and delicate inward-folding internal screens, servicing the rear camera cluster requires careful isolation of the primary outer panel. Expect to work around tightly packed internal brackets, delicate flex cables, and strong factory adhesives while keeping the folding displays completely protected.

1. 1

   Power down and prepare the workstation

   • Lay the device fully unfolded on a clean, padded anti-static mat so no pressure points press against the interior folding display.
   • Turn off the device completely and remove the SIM card tray using an ejector tool.
2. 2

   Heat the primary camera back panel

   • Position your heating pad at 75°C (167°F) directly under the rear panel housing the camera module for 4 to 5 minutes.
   • If using a heat gun, keep the nozzle moving around the outer perimeter to soften the perimeter adhesive without overheating the internal battery.
3. 3

   Create the initial opening gap

   • Attach a suction handle near the bottom corner of the rear glass panel and pull upward to create a hairline separation.
   • Slip a thin plastic pick into the gap, keeping insertion depth under 3 mm to avoid severing underlying sensor ribbons.
4. 4

   Cut the perimeter adhesive

   • Work the pick smoothly around the perimeter of the panel, applying a drop of isopropyl alcohol to stubborn adhesive areas if needed.
   • Take extra caution along the hinge edge, making sure your tool never slips toward the hinge mechanism or internal screen frame.
5. 5

   Lift and remove the back cover

   • Gently lift the back glass panel away from the frame once all adhesive seams are sliced.
   • Set the panel aside on a microfiber cloth to prevent scratching the camera lens covers.
6. 6

   Remove the upper motherboard shield

   • Unfasten the Phillips #00 screws securing the protective graphite-lined bracket covering the logic board.
   • Lift the shield away with tweezers to expose the camera module and motherboard connectors.
7. 7

   Disconnect the battery immediately

   • Use the flat end of a nylon spudger to pry up the primary battery press-fit connector from the motherboard.
   • Cutting system power at this stage prevents short circuits while working near sensitive board traces.
8. 8

   Disconnect the camera module flex cables

   • Locate the three separate camera ribbon cables for the primary 200MP wide lens, telephoto lens, and ultrawide sensor.
   • Gently disconnect each flex connector straight up from the motherboard socket using a plastic spudger.
9. 9

   Extract the damaged camera cluster

   • Remove any remaining retaining bracket screws securing the camera assembly to the aluminum frame.
   • Use blunt tweezers to lift the camera block upward and out of its chassis recess, taking care not to scrape thermal pads underneath.
10. 10

    Install the replacement camera assembly

    • Position the new OEM camera module into the frame alignment pins and press it into place until seated level.
    • Reconnect each camera flex connector, feeling for a tactile snap to ensure complete contact.
11. 11

    Perform a diagnostic bench test

    • Reconnect the battery cable, gently rest the back cover on the chassis, and boot up the phone.
    • Open the Samsung diagnostic menu by dialing *#0*# to verify focus, zoom switching, and sensor stability before final sealing.
12. 12

    Reseal the rear panel

    • Power the device off, clean away all remaining factory adhesive with isopropyl alcohol, and apply the fresh pre-cut adhesive seal.
    • Align the back glass over the chassis, press firmly around all edges, and clamp with padded repair clamps for 20 minutes to set the bond.
