I had the internation Galaxy S as well and never my GPS worked, I say again __NEVER__ even after the Samsung promised fix. Lots and lots of lag when doing anything, the screen was awful with blue tint (it was marketed that amoled was much better than lcd at the time, a f*ing lie), battery was mediocre. Maybe you are talking about Galaxy S 2? I had mine in 2010.

Hmm mine was a hands-me-down from my father, and I actually never used a S2 lol Went from Galaxy S to iPhone 4S to Note 2

I think I fixed the GPS by following an instruction in XDA.... I don't remember, its been 5 years already? God I feel old
