I'm trying to use Tasker and it's Location Based feature to fire off certain events (turn volume down when I'm at work, etc.). However, the GPS seems to be freaking out whenever I'm at work. I'm watching my location in the Maps app consistently jumping around between a spot a couple of miles away from the office and a spot about a mile from my house -- which is about 15 miles away. I have GPS turned off so it's using the towers to calculate my location. I get about 3/6 bars on average when I'm at work. So I'm wondering why it's bouncing around. Turning on the actual GPS doesn't seem to help, either. Any ideas what might be going on?
