The other cannot hear any voice when adjusting the buttons of the 3.5mm earphones during voice/video calls on the Redmi Pad Pro

When using 3.5mm earphones during voice or video calls on the Redmi Pad Pro, the other party cannot hear any voice briefly when you adjust the earphone buttons.
This occurs because the device temporarily mutes the microphone to prevent any noise or interference that will be generated by the adjustment process. The muting feature helps ensure that adjustments to the earphone buttons do not produce unwanted sounds or disturbances during the call.
This behavior is a normal design aspect of the device and does not indicate a problem with the earphones or the device itself. Feel free to use your earphones and adjust the buttons as needed, keeping in mind that this brief mute is intended to enhance call quality.
