Xamarin.Forms.Maps - Releasing Memory

I'm on Android, I have a simple map page with a map added to a StackLayout, then set as the content for a ContentPage. If I continually open and close the map page, zoom and pan around, it does not seem that RAM gets reclaimed even after GC.Collect(). Not adding any pins or anything like that - seems that memory will continually increase without letting go (even after page is popped). Is it a better option to render the map in the Android project? I'm on Xamarin.Forms 1.3.1.6296.

Thanks!
