Samsung Galaxy Z Flip7 FE Inner Screen Replacement

A broken inner foldable display on your Samsung Galaxy Z Flip7 FE usually presents as dead pixels, a completely black screen, or a bleeding ink effect along the crease. Because the flexible AMOLED panel is extremely fragile, the most reliable repair method uses an OEM Service Pack where the new screen comes pre-installed in a metal frame. Expect a tedious process requiring you to transfer the motherboard, batteries, and smaller components from your old housing into the new assembly.

1. 1

   Heat the back glass panels

   • Apply gentle heat to the upper and lower back glass panels using a heat gun to soften the adhesive.
   • Place a suction cup on the glass to pull up slightly, and then insert a plastic pick into the gap to slice through the adhesive around the perimeter.
2. 2

   Disconnect the batteries

   • Safety must always come first when working inside a smartphone.
   • Remove the protective metal shields covering the motherboard by unscrewing the Phillips screws, and then use a plastic spudger to disconnect both battery flex cables.
3. 3

   Remove the lower board and flex cables

   • Carefully disconnect the interconnect flex cables that bridge the top and bottom halves of the phone.
   • Unscrew and gently lift out the lower board containing the charging port and microphone.
4. 4

   Extract the motherboard

   • Disconnect the camera cables and any remaining antenna wires attached to the main board.
   • Remove the securing screws and carefully lift the motherboard out of the upper housing using your fingers or a plastic spudger.
5. 5

   Transfer the batteries

   • Apply a few drops of isopropyl alcohol around the edges of both batteries to dissolve the strong factory adhesive.
   • Wait a couple of minutes before gently prying them out with a flat plastic tool, being extremely careful not to puncture the lithium-ion cells.
6. 6

   Move the small components

   • Use tweezers to carefully transfer the vibration motor, earpiece speaker, and any small rubber gaskets from the old frame.
   • Proper placement of these tiny components in the new Service Pack frame is crucial for water resistance and functionality.
7. 7

   Install the logic boards into the new frame

   • Place the motherboard and lower sub-board into their respective slots in the new screen assembly.
   • Secure them with their original Phillips screws and reconnect the camera modules.
8. 8

   Seat the batteries and reconnect cables

   • Apply new adhesive strips to the battery compartments and press both batteries firmly into place.
   • Reconnect the interconnect flex cables between the two halves of the device, but leave the battery connectors unplugged until the very end.
9. 9

   Test the new display

   • Snap the battery connectors into place and temporarily power on the device to ensure the new inner screen functions correctly.
   • Check the touch response and look for any display anomalies before proceeding to the final seal.
10. 10

    Seal the back glass panels

    • Once you confirm the phone works perfectly, power it down and apply fresh pre-cut adhesive to the back of the frame.
    • Press the upper and lower glass panels firmly into place and apply gentle, even pressure for an hour to ensure a watertight seal.
