I'm trying to get down to the bottom of this to determine what the problem actually is. With an iPhone 6, and T-Mobile, and iOS 8, location services shouldn't be as big as a problem as it is for me. I find myself having to reset locations daily. Non-stop. Somewhere along the line, the iPhone finds itself unable to determine my location in any of its apps. As if the GPS was malfunctioning. Is it GPS? iOS 8? Or T-Mobiles crappy service? Something is happening that shouldn't be.
