Adding ActivationPolicy="Resume" is not the only step needed to have your app support Fast App Resume. I believe the behavior you are describing is normal when you only set that one property. I think there are a few ways to implement "Fast App Resume", but I found this to be the easiest way.

Set the activation policy like you just described and then do the following:

Go into App.xaml.cs in the "App" class add:

   private bool reset

You should then have a method for InitializePhoneApplication that initializes the RootFrame. Add this:

RootFrame.Navigating += RootFrame_Navigating;
RootFrame.Navigated += RootFrame_Navigated;

Then you can go and add those methods:

void RootFrame_Navigating(object sender, NavigatingCancelEventArgs e)
{
    if (reset && e.IsCancelable && e.Uri.OriginalString == "/MainPage.xaml")
    {
        e.Cancel = true;
        reset = false;
    }
}

void RootFrame_Navigated(object sender, NavigationEventArgs e)
{
    reset = e.NavigationMode == NavigationMode.Reset;
}

If you implement this properly, your app should resume from the last page you were on.
