I have an Android tablet, but not a smart phone. I'm not hugely careful with what I stick on there, but I think I've only shared my contacts with stuff like Hangouts and Skype (where the explicit purpose of the app is to contact people). I increasingly leave my cell phone sitting at home (mostly because I don't care about being reachable, not because I'm worried about network location pings). I take it with me if I'm going to be away for more than a couple hours.

As far as not using analytics, it's a combination of not caring (as an example, I run (maybe I should say jog?) regularly but don't time myself) and distaste over the way the data is managed.
