Samsung Galaxy A07 Charging Port Replacement

Is your Samsung Galaxy A07 struggling to charge, losing connection when bumped, or completely dead? A faulty USB-C charging port is a common issue that can easily be fixed at home with the right tools. This guide will walk you through replacing the charging port sub-board to get your device powering up reliably again. Expect to work with small screws and adhesive, so patience is key.

1. 1

   Power Off and Remove SIM Tray

   • Turn off your Samsung Galaxy A07 completely before starting any repairs.
   • Use a SIM ejector tool to remove the SIM card tray from the side of the device.
   • This prevents damage to the motherboard during disassembly.
2. 2

   Heat the Back Cover

   • Apply heat to the edges of the plastic back cover using a heat gun or hair dryer for about two minutes.
   • Keep the heat source moving to avoid melting the plastic or damaging the internal battery.
   • This softens the adhesive holding the panel in place.
3. 3

   Pry Open the Back Cover

   • Place a suction cup near the bottom edge of the back cover and pull up gently to create a small gap.
   • Insert a plastic guitar pick into the gap and slide it around the perimeter to slice through the adhesive.
   • Once all edges are free, carefully lift the back cover away from the phone.
4. 4

   Remove the Mid-Frame Screws

   • Locate and remove all the Phillips #00 screws securing the plastic mid-frame and loudspeaker assembly.
   • Keep your screws organized on a magnetic mat so you know exactly where they go during reassembly.
5. 5

   Disconnect the Battery

   • Gently pry off the motherboard shield to expose the battery connector.
   • Use a plastic spudger to lift the battery flex cable straight up from its socket.
   • Disconnecting the battery immediately eliminates the risk of short-circuiting components while you work.
6. 6

   Remove the Loudspeaker Assembly

   • Pry up the bottom loudspeaker module which sits directly over the charging port board.
   • Lift it out of the chassis and set it aside.
   • This exposes the USB-C charging sub-board and its connected cables.
7. 7

   Disconnect the Sub-Board Cables

   • Use your plastic spudger to disconnect the main flex cable that links the charging board to the motherboard.
   • Next, use tweezers to carefully snap off the coaxial antenna cable from its socket on the charging board.
8. 8

   Extract the Old Charging Board

   • Remove any single Phillips screw holding the charging port board in place.
   • Insert a spudger underneath the board and gently pry it up from the bottom of the phone.
   • If it feels stuck, apply a tiny amount of isopropyl alcohol to loosen the mild adhesive underneath.
9. 9

   Install the New Charging Port

   • Align your replacement Samsung Galaxy A07 charging port board into the bottom housing.
   • Press it down gently so the microphone and USB-C port sit flush against the frame cutouts.
   • Secure it with the mounting screw.

    Reconnect Cables and Reassemble

    • Snap the coaxial antenna cable and the main flex cable back onto the new charging board.
    • Reinstall the loudspeaker assembly, reconnect the battery, and screw the mid-frame back into place.
    • Finally, apply new adhesive or B7000 glue to the edges of the phone and press the back cover firmly to seal it.
