If the Mi 13 microphone hole is poked by the card pin, it may cause the microphone to malfunction or damage. Because the microphone hole is one of the important parts of the millet 13, once it is punctured, it will affect its recording effect and call quality. Therefore, it is recommended to avoid using needle-like items to contact the microphone hole as much as possible to avoid unnecessary damage. If the microphone hole is accidentally punctured, it is recommended to contact the after-sales service or replacement in time.
