Remove underline on Android and iOS

How can I remove the underline on Androind and iOS?

I already tried the following that works in the Xamarin.Forms (Android) controls that I customize:

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

            if (Control != null)
            {
                GradientDrawable gd = new GradientDrawable();
                gd.SetColor(global::Android.Graphics.Color.Transparent);
                this.Control.SetBackground(gd);

                this.Control.SetRawInputType(InputTypes.TextFlagNoSuggestions);
            }
        }

I'm using plugin's last version (1.1.1) on Xamarin.Forms (4.7.0.1080).

Regards.

Also, how can I set the default text color? I tried using "Black" but it seems that is darker than default.
