I have abandoned using Osmand for location sharing although I use it exclusively for routing on adventure rides. I am now playing with Google Location sharing. It works well in urban areas when I stop at a retail location, which is a little creepy. I works intermittently when I am moving, and not at all out of cell range. I will continue to experiment, but my current opinion is that it either works too well when I don't need it, and not at all when I do.
