I save a map to an android device and it works, but I see a couple of strange things:

1. When I move the map past the bounding box saved (using gestures), the background does not redraw so the edge is "smeared" across the page. (this is the least problematic issue of the 3)
2. When I zoom in too much (perhaps past what was saved, don't know for sure) the map freezes and I need to zoom in/out.
3. Even when not zoomed in all the way, moving the map "smears" the graphic and markers within the bounding box of what was saved (zooming in/out cleans it up).

Are these known issues?
