I love it when people are always confused about A-GPS.
A-GPS is BETTER than just GPS.
Assisted GPS means, that instead of just relying on the GPS satllites, it helps setting the position from WIFI and cell network.
It does NOT cost any money.
It is also handy, when you are indoors, so your device does not get a position fix from GPS satellites.
Besides, this samsung receives the Russian GLONASS satellites in addition to the American GPS, so its very precise.
My 10.1 tab2 (has the same receiver) sees 15+ satellites indoors!
GPS test shows precision down to 1m.
