    I know that the microphones will switch off for the type of video recording.. But how do they work when on the phone?

    I remember reading something about 2 of them being used to evaluate and filter out background noise, making YOUR voice sound clearer to the person on the other line. Maybe someone could confirm that.

    You are correct. They are used for active noise cancellation.
