Hi Screech: Thanks for the reply. I had an iPhone 3gs before I started using this Galaxy s4 a week ago for about 4 years. Used the same program (RunKeeper) and for a 3.1 mile run, it would read 3.1 or 3.2 miles. It was very accurate. On the map trail there were very few wavering lines. It tracked very well.
I will do some checking on this Qstar you are talking about.
Thank you very much.
