Xamarin.Forms: change text size on DatePicker

I created the following custom renderer, but it only changes the selected value size

[assembly: ExportRenderer(typeof(DatePickerCustom), typeof(CustomDatePickerRenderer))]
namespace Vendo.Android.Renderers
{
    public class CustomDatePickerRenderer : DatePickerRenderer
    {
        public CustomDatePickerRenderer(Context context) : base(context)
        { }

        protected override void OnElementChanged(ElementChangedEventArgs<DatePicker> e)
        {
            base.OnElementChanged(e);

            if (this.Control == null)
                return;

            Control.TextSize = 16;
        }
    }
}

I need to change the text size this way:
