I've built an app for our local trail system on the Kenai Peninsula, Alaska. If I use the My Location tool/widget out on the trail, it shows my location as atleast a mile away. If I turn my phone Location Settings to "GPS Only" (I have an Android), it finds my location eventually. I'm not sure how to do the same in an iPhone, but am also wondering why we'd need to do this at all? Has anyone else experienced this?
