Just like the first Moment I had, GPS performance started out poor and got worse till no lock is possible. When my first unit went bad in November and was swapped, all I could see was that the icon kept flashing. Now with GPS test I can see that in the middle of my yard with no obstructions to a clear sky, the phone sees 6 sats at best, none strong enough to lock. Every minute or so, it looses all the sats for ~10 to 20 sec then starts acquiring again. I'm thinking of waiting till after the 11th, maybe they'll be out of Moments and offer me an Intercept. I'd be deliriously happy just to have a Moment that has a useful GPS and doesn't suffer from CDMA Lockup. FU Samsung!
