This morning I turned on Google Maps. I have it set so there's an arrow pointing in the direction of where the phone is pointing. It only showed East no matter which direction. I figured that was because I have a network extender and it may cause problems. I then went a mile away and it had the same problem. Sure it was the right location, but the wrong direction.
I have GPS Status as an app so I tried it. It showed the satellites, but North was now East on the compass! I took it to the Verizon store and added the app to the Droids they had for display. They were more correct, but mine was the worse. I showed it to the tech and they couldn't get it working right. In the end they did a hard reboot which cleared it up.
I was wondering if anyone else had that problem and how they solved it.
