Hi,
I perform Android app updates only once or twice a week (manually).
Today there were, amongst others, Navigator and Zoom to be updated. Navigator needed about 5 MB, Zoom about 150 MB (5GB free), and Zoom took LESS time than Navigator to update.
This makes me wonder what's happening "under the bonnet" when Navigator is updated.
[I've installed maps for all those regions that I tend to visit - D, NL, B, F, southern GB, IRL; does THIS cost so much time? If so, WHY?]
