Went to the store yesterday and exchanged my captivate. When I got into the parking lot, I was pleasantly surprised to find my gps lock on almost instantly and pin point accurate. Drove around the parking lot and it followed me perfectly. Turned gps off, drove up the road, and turned it back on to see if it could find me again, same thing, found me in <10 seconds and followed me perfectly. Turned GPS off again and drove further away, turned it on, same results. Great! Got home, and played with the phone a bit, set up ringtones, etc, downloaded a few apps, nothing major, a game or two, engadget app, etc. Went outside my house, turned the GPS on...took about 30 seconds to lock. Strange it took so much longer than it had been, but still, 30 seconds isn't terrible. Fast forward to today. I still haven't done anything major to the phone, the most "hacky" things I've done to it are root it and put clockwork on, neither of which should affect the GPS, and now I go outside and after a minute I couldn't get a lock. I'm not the first person I've heard of that had a new unit work perfectly out of the box, only to have it stop working soon after. Looking to find out how many people this has happened to, and if we can get an idea what might be causing it. Has anyone done NOTHING to their phones, no apps, no mods, etc, and still had this degradation in performance? Maybe we can find some kind of explanation for this.
