I have been using Google Navigation on my Droid 3 for a while now. Usually it works great but every once in a while it will loose the signal and it says it is "searching for gps" and will not reconnect! This is even in an area where I have full bars and is never very far from home where it has found satellites before. Shouldn't it be able to locate me using cell towers when there is a full signal? It says "searching for gps" for a very long time as well. When I power on/off the phone it works fine in the same location that was previously having the issue. I recently installed "GPS Test" and it says it is working fine. It found satellites in no time at all. Could this be a software glitch or another app interfering? Thanks in advance for any help!
