Integrated Functions
When you replace this sub-board module, you are replacing several features grouped onto the same flex piece:
- USB Charging Port: Fixes loose connections, intermittent charging, or total lack of power delivery.
- Microphone Module: Solves issues where callers cannot hear your voice during cellular or internet calls.
- Headphone Audio Jack: Restores functionality to wired headphones and auxiliary connections if sound cuts out.
- Antenna Signal Pass-Through: Contains connection terminals that link the cellular signal wire to the primary logic board.
Signs You Need to Replace the Flex
Consider getting a replacement part if your phone exhibits any of these symptoms:
- The device only charges when the cable is pushed or bent at a precise angle.
- Fast charging protocols fail to engage with an original wall adapter.
- The phone fails to register any data transfer when plugged directly into a computer.
- The microphone stops working at the same time the charging port acts loosely.
