I have Forms app with Navigation page and content page on it. I want change background on page (during rotation of device but for test is possible to use button click). But it doesn't change at all. Code can looks like :
public partial class MainScreen : ContentPage
BackgroundImage = "landscape.png";
public async void ButtonAction(object sender, EventArgs args)
BackgroundImage = "portrait.png";
Update - problem is probably only on Android.
On iOS (iPhone 6 Plus) and WP8.1 (N930 Denim) looks ok, Android 4.4.4 on Nexus 5 don't work
