Symptoms This Part Resolves
- The phone only charges when the cable is held at a specific angle.
- The device does not register the USB cable or show a lightning bolt icon.
- Computer connection fails to recognize the phone for file transfers.
- Microphone issues (as the main microphone is typically integrated directly onto this sub-board).
Installation Overview
Replacing the flex is a straightforward component swap. You will need to remove the phone’s back housing, unscrew the lower loudspeaker assembly to reveal the sub-board, detach the main motherboard ribbon flex, and swap out the faulty board. If you lack fine plastic prying tools or precision screwdrivers, it is highly recommended to take the part to a local technician to protect internal components like the sensitive fingerprint sensor cable.
