Has anyone else experienced a horrible decrease in the accuracy of your GPS position? My phone used to be pretty accurate sitting at my desk indoors, but now it's HORRIBLE. My position radius is HUGE. Usually, if I turn on wi-fi, it becomes pretty accurate, but I used to not have to do that just to get an accurate reading. However, I'm looking at Maps right now, with wi-fi enabled, and the radius is huge. What gives? EDIT: After ten minutes of sitting here with wi-fi on, the accuracy dropped to something more reasonable. But only for a couple seconds! Now it's huge again, but not as huge as before.
