In all emulators (Android, Windows Phone)
Welcome to Xamarin.
That's the nature of Emulators - they suck. The good ones just suck, less.
Even when they work - they don't - there's plenty of threads about certain things not rendering the same on an emulator as real hardware and so on.
Go to your cell provider, or Sams club and get a $50 Android tablet so you can debug to real device.
