Overview
What this part is
The USB-C charging port on the Samsung Galaxy A12 sits on a small board at the bottom of the phone. The port is used every day, so it wears, and lint or corrosion can stop the charger making good contact. The board is supplied with the charging IC already fitted.
Replacing the whole board is cleaner and more reliable than soldering a new socket. Before ordering, try a different cable and charger and clean the port gently, as a dirty port or faulty cable causes the same symptoms.
