  I think it is supposed to be this, but this only seem to work on iOS

              var MainPage = new Xamarin.Forms.NavigationPage(new Pages.Page())
              {
                  BarBackgroundColor = Color.FromHex("#488FCE"),
                  BarTextColor = Color.White,
              };

  There is some toolbar behaviours override out of the box.

  Please check the documentation.
  https://docs.microsoft.com/en-us/xamarin/xamarin-forms/platform/platform-specifics/

  Native Android (can override the theme in Forms)
  https://docs.microsoft.com/en-us/xamarin/android/user-interface/controls/tool-bar/replacing-the-action-bar

  Please follow these github features and bug the Forms team to push them through or help if possible.

  We can achieve this using Effects in Xamarin forms.

  In the shared project

  public class StatusBarEffect : RoutingEffect
  {
  private static Color BackgroundColor;
  public static void SetBackgroundColor(Color color)
  {
  BackgroundColor = color;
  }
  public static Color GetBackgroundColor()
  {
  return BackgroundColor;
  }

       public StatusBarEffect() : base ("Xamarin.StatusBarEffect")
       {}
   }
  

  Code for iOS

  assembly: ResolutionGroupName("Xamarin")]
  [assembly: ExportEffect(typeof(MyStatusBarEffect), "StatusBarEffect")]

  namespace yournamespce
  {
  public class MyStatusBarEffect : PlatformEffect
  {
  protected override void OnAttached()
  {
  UIView statusBar = UIApplication.SharedApplication.ValueForKey(new NSString("statusBar")) as UIView;
  if (statusBar.RespondsToSelector(new ObjCRuntime.Selector("setBackgroundColor:")))
  {
  statusBar.BackgroundColor = StatusBarEffect.GetBackgroundColor().ToUIColor();
  }
  }

       protected override void OnDetached()
       {
  
       }
   }
  

  }

  you can use the statusbar effect as follows in the onappearing method:

  protected override void OnAppearing()
  {
  base.OnAppearing();
  StatusBarEffect.SetBackgroundColor(Color.Green);
  this.Effects.Add(new StatusBarEffect());
  }

  This solution mainly depends on Jorge Ramirez post.
