    [FM] FM radio "Plug in headphones" view will flash twice after plugging out headphones while searching

    First time launch FM and play a station -> Tap Radio
    Station button -> Plug out headphone while searching
    station -> Check the display, "Plug in headphones" view
    will flash twice.

    When plugging out earphone in Radio Station screen, it's
    no need to start animation to show no earphone view. Just
    show no earphone view.
