Common Symptoms of a Faulty Charging Flex
You likely need to replace this part if your phone is experiencing:
- No charging response or a loose, disconnected feeling when plugging in the cable.
- Slow charging or failure to trigger Huawei “SuperCharge” protocols.
- Microphone issues during phone calls (as the primary mic is often soldered onto this exact same sub-board).
- Computer connectivity issues when attempting to transfer data via USB.
