My Droid was great, used Google Maps constantly for several months. The past several days, it started losing GPS signal lock, and today can't get a lock after half an hour with clear sky above. I have "GPS Status" app, and it shows that it is receiving signal from between 5 and 8 satellites, but none of them show as locked. Any ideas? I have already rebooted the phone, removed battery, etc. multiple times. I have turned off wifi and bluetooth with no effect.
