Yes, I have the same problem. It has a mind of it's own. I didn't manage to find the right recipe to make it always work (reboots, enable/disable, clearing cache agps etc). I've installed some additional software to clear the agps and it manage to see the sattelites (22, 24, even 27) but it wouldn't connect to any of them. Sometimes, suddenly connects after 30 minutes, for example, out of the blue, while not running anything or running the same software.
