Galaxy S charging port boards (tail connectors) with USB-C port and microphone — fix charging and data faults.
The charging port board also carries the main microphone on many models, so it often fixes call audio problems as well as charging faults.
More cables: flex cables.
On most Galaxy S models the USB port and the main microphone sit on the same charging board, so replacing it fixes both charging and call audio issues. Disconnect the battery first and route the main flex exactly as before.
