Hello,I have Samsung Galaxy S2 - Android 2.3.3.I use SpotTracker for a couple of months for hiking and I'm really pleased with it.So far everything is working perfectly and the GPS was very accurate.But lately when I use SportTracker my GPS completely crazy and shows the incredible speed of movingbetween Bosnia and Herzegovina (where I live) and Africa. In half an hour so passes over 20000km. I thought it was a problem in the application SportTracker, but Today I installed Endomondo and the same was happening to me with that applicationI think the GPS on my phone fine because it works fine with Google maps when SportTracker (or Endomondo) disabled.Here you can see what I mean: Sports Tracker the last 15 days this problem I have always. I ask for your help.Thanks in advance.Midhat
