Required Tools

• Heat gun or heating pad
• Suction handle
• Thin plastic opening picks
• Nylon spudger

Step by step

1. 1

   Step 1: Power Down and Eject the SIM Tray

   Turn off the Samsung Galaxy A08 4G completely before opening the device.

   Insert the SIM eject tool into the pinhole on the left edge of the phone to remove the dual-SIM and microSD card tray.

2. 2

   Step 2: Heat the Rear Cover

   Apply uniform heat around the perimeter of the back panel using a heat gun set to 70-80 degrees Celsius for two to three minutes.

   This softens the factory adhesive holding the rear panel firmly against the inner chassis.

3. 3

   Step 3: Slice the Adhesive Perimeter

   Place a suction handle near the bottom edge of the back panel and pull upward to create a hairline opening.

   Insert a thin plastic pick into the gap and slide it slowly around all four edges to slice through the perimeter adhesive.

4. 4

   Step 4: Remove the Back Panel

   Gently lift the rear panel off the frame once the adhesive has been completely severed.

   Set the panel aside in a clean area away from dust and stray debris.

5. 5

   Step 5: Disconnect the Battery

   Remove the Phillips screws securing the protective mid-bracket covering the main logic board.

   Lift the bracket off and use the flat end of a plastic spudger to disconnect the battery flex cable, cutting electrical power to prevent accidental shorts.

6. 6

   Step 6: Remove the Loudspeaker Assembly

   Unscrew the Phillips screws securing the lower speaker enclosure at the bottom of the phone.

   Pry the speaker module gently out of its housing to reveal the charging daughterboard resting underneath.

7. 7

   Step 7: Disconnect the Sub-Board Cables

   Use a plastic spudger to pry the primary interconnect ribbon cable off the daughterboard connector.

   Use precision tweezers to lift the miniature RF antenna coaxial cable straight up from its socket on the board.

8. 8

   Step 8: Detach the Damaged Charging Board

   Remove any retaining Phillips screw holding the charging board to the chassis.

   Insert a flat spudger under the sub-board to free it from the mild adhesive underneath, then lift it clear of the frame.

9. 9

   Step 9: Install the Replacement Daughterboard

   Lay the new charging daughterboard into the lower recess, aligning the USB-C socket, microphone port, and headphone jack with the frame openings.

   Press down gently so the board seats flush against the alignment pins.

10. 10

    Step 10: Reconnect the Flex and Coaxial Cables

    Reattach the main interconnect flex cable by pressing the connector firmly until it snaps into place.

    Carefully align the RF coaxial antenna head over its socket and press it straight down without bending the delicate central pin.

11. 11

    Step 11: Secure the Speaker and Test the Port

    Place the loudspeaker assembly back into position and drive in its Phillips screws.

    Reconnect the battery flex cable, turn on the phone, and plug in a USB-C charger to confirm that charging and microphone functions work properly before final assembly.

12. 12

    Step 12: Reseal the Back Cover

    Power the device back off, wipe away old adhesive residue from the perimeter with a drop of isopropyl alcohol, and apply fresh adhesive.

    Press the back cover firmly onto the chassis around the entire border, then slide the SIM tray back into the phone.
