I have found that on my Androids, I have to have a GPS app running on the phone else it will use cell towers for location. Unless I do that, tracking is rarely accurate and often the position shifts at what would have had to have been several hundred MPH.
I use mobiwia.com’s GPS Status app from Google Play and have it running.
Does that app let me download the full data set for my own travels? That’s what I need here.
