Step-by-Step Repair Instructions
Step 1: Power Off & SIM Tray
First, turn off the phone completely.

Step 2: Remove the Back Cover
Create a small gap near the SIM slot or charging port using a picker or plastic card pry tool.
Insert the pry tool and gently move around the phone to release the plastic clips on the frame.

Disconnect the battery connector first.
Disconnect the required flex cables and undo the board screw.
Carefully lift and remove the logic board from the frame.

Locate the earpiece speaker at the top of the frame.
Apply gentle heat if necessary and carefully lift out the faulty earpiece speaker.
Step 6: Install the New Earpiece Speaker
Place the new Galaxy A13 4G earpiece speaker into position.
Ensure it sits flat and aligns correctly with the sound outlet.
Step 7: Reinstall the Logic Board
Place the logic board back into position and secure it with the screw.
Reconnect all previously disconnected flex cables.
Step 8: Reinstall the Board Frame
Position the board frame back onto the phone and secure it using the screws removed earlier.
