Samsung Galaxy Z Flip7 Charging Port Replacement

If your Samsung Galaxy Z Flip7 is struggling to charge, losing connection when the cable is bumped, or failing to fast charge, the charging port board likely needs replacement. This repair requires opening the lower glass back panel to access the internal daughterboard. You can expect to work with delicate flex cables and strong adhesive, so patience is essential to avoid damaging the foldable display or internal components.

1. 1

   Heat the lower back panel

   • Power off your phone completely before beginning the repair.
   • Apply gentle heat to the lower back glass panel using a heat gun or heating pad to soften the factory adhesive.
   • Keep the heat moving to prevent burning the glass or internal battery.
2. 2

   Slice through the adhesive

   • Place a suction cup near the bottom edge of the heated glass and pull up slightly to create a small gap.
   • Insert a plastic guitar pick into this gap and carefully slice around the perimeter.
   • Avoid inserting the pick too deeply to protect the internal flex cables.
3. 3

   Remove the lower glass panel

   • Once the adhesive is fully separated, gently lift the lower back glass away from the frame.
   • Clean any leftover adhesive residue from the metal frame using tweezers and a few drops of isopropyl alcohol.
4. 4

   Disconnect the lower battery

   • Safety is the top priority when working inside any modern smartphone.
   • Unscrew the Phillips screws securing the lower protective metal shield and remove it.
   • Use a plastic spudger to gently pry up and disconnect the lower battery flex cable to cut power to the board.
5. 5

   Disconnect the interconnect cables

   • Locate the main interconnect flex cables that bridge the top and bottom halves of the phone.
   • Carefully pry their connectors straight up from their sockets on the charging port board using your plastic spudger.
   • Move these cables out of the way so you have clear access to the daughterboard.
6. 6

   Remove the old charging port board

   • Unscrew the remaining Phillips screws holding the charging port board in place.
   • Gently lift the board out of the lower housing using tweezers or your fingers.
   • Check the empty cavity for any dust or debris and clean it out if necessary.
7. 7

   Install the new charging port

   • Align your new GH96-19729A charging port board into the lower housing.
   • Press it down gently so it sits flush and secure it by reinstalling the Phillips screws.
   • Reconnect the interconnect flex cables by pressing them straight down until they snap into place.
8. 8

   Reconnect the battery and test

   • Snap the lower battery flex cable back into its socket on the new board.
   • Before sealing the phone, plug a charging cable into the new port to verify that the device charges properly and fast charging works.
   • Once confirmed, reinstall the protective metal shield and its screws.
9. 9

   Seal the device

   • Apply new precut adhesive strips around the perimeter of the lower metal frame.
   • Press the lower back glass panel firmly into place and apply steady pressure for a few minutes to ensure a tight, water-resistant seal.
