Android GPS Failing

I used the GPS navigation of my Samsung Galaxy S2 a lot while traveling on the West coast. It was great. Then when I got back to the East coast, that feature stopped working. If I went into Google Maps and tried to navigate somewhere, the bottom of the screen displated "Searching for GPS..." the entire time. Strange, because it was able to identify my current location.

I got it to work (for now, anyway) by turning off GPS. Then turn off the phone for 5 minutes. Then turn it on, and turn on GPS. Working now.

I'm not sure how long that will last and how often I'm going to have to do that, but as often as I need GPS navigation, I'm willing to do that if it works every time.
