Hi Android Forum: This is my first post and I hope to do it correctly. I did a search and could not find what I am about to ask. I just purchased a Galaxy s4 and love it. I do have one problem. I love to get outdoors and run, hike, bike and the like. I use the app called RunKeeper. For some reason this new phone is not as accurate as my old iPhone. I can run a distance of 3 miles and my old phone was dead on (3 miles). With my new phone it shows 3.40 miles or close to that. It is not accurate. I then tried two other running apps: Nike+ and MapMyRun. Both of them are not accurate either. All three apps add about 1/2 mile to a 3 mile run. If you look at the track on the map after the run, the iphone map has some pretty straight lines, the Galaxy s4 has really "S" shape lines adding the extra miles. It just does not track very well. I have access to my location ON, I have use GPS satellites ON and I have use wireless networks ON. I called Samsung support and they said they know about the problem and a fix should have been out by now. Anyone have any idea on what I can try. Or do you know of a fix. It is just not very accurate. Thank you very much.
