After installing the latest update on my phone (Lumia 920), it is having problems finding my specific location. When I open any app that uses location it takes 5 minutes or more to lock on to my location. This is happening regardless of my surroundings. Once it does find my location, and I begin driving around, it fails to track my movement and intermittently reacquires my location then loses me again and again. My wife's phone is not having this issue (also a 920). Prior to this update my phone would acquire my location within seconds. I've searched online and can find no one else reporting this problem. Am I the only one experiencing this?
