Microphone Flex Cable for Xiaomi Mi Mix 4 5G

The Microphone Flex Cable / Patta in your Xiaomi is the ribbon cable that carries the audio signal from the microphone capsule to the motherboard's audio processing circuit. When it is torn, kinked, or has a broken connector, the microphone signal cannot travel to the motherboard — causing absent or intermittent microphone input on calls, recordings, and voice commands on your Xiaomi even when the capsule itself is undamaged.

If the microphone stopped working after a repair that involved opening the bottom of the phone — where the microphone flex typically routes on most Xiaomi devices — the flex cable is the first component to inspect. Visible kinking, tearing, or connector damage confirms the flex as the fault. If the cable appears intact, the microphone capsule or Microphone IC should be tested next.

Yes. The connector type, cable dimensions, and routing are model-specific. This listing is designed for Xiaomi only. A flex from a different model will not connect correctly and may damage the motherboard audio connector.

It is a moderate repair requiring the phone to be opened and the flex carefully disconnected and replaced. No soldering is required in most cases. Professional tools are recommended to avoid damaging the ZIF connector on your Xiaomi .

Yes — a 7-day replacement warranty covering manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Flex cables showing physical damage from improper installation are not covered under warranty. For more information, check out SAHII's Return Policy.
