Yes, you are absolutely right!
I disabled "Automatic Overview" and now it runs smoothly.
I was crazily hunting for what that Icon means, and yes due to high elevation/zoom view it seems, the navigation has been stopped!
I think, while experimenting I mixed too many things and lost the correct set of apk+UX+data.zip.
Now, everything is working fine.
Thank you very much friends- frontzosd, arhd, quartzo, wojpen,catymag and everyone here.
