My old Droid X phone broke so my brother in law gave me another Droid X until our upgrade. I geocache and use the live-geocache app. My old DroidX worked great on the map feature and the GPS was very accurate. This DroidX I have now is off by miles. I think it is using cell towers to pinpoint me. How can I get the GPS to work like the old phone? I ran GPS Test app and I am getting 8-9 satilites.
