Hi all - I've got the same issue on the S3 with ver 6.9.0, but just using Google Maps, not even for navigation. The problem seems to happen when you zoom in to a certain level. For example, if you look at a map of the entire UK, no problem. But try zooming in to see central London (even without satellite layer) and it goes nuts. If you can get enough control over it to zoom out again, it stabilizes once more. This is very reproducible.
