Now I've only had this phone for a few days so my input might not be as strong as others, but from my experience so far, the gps on my captivate has been running smoothly. it locks on and does it fairly quick. I think the longest was around 20 seconds or so with accuracy being 5-10 meters. This is indoors too with wifi off as well as on. Navi works spot on as well. Only time it didn't work was when I was driving through a deadzone area out in the middle of nowhere.
Coming from an iphone 3g I can say I love the freedom. I love not having to use itunes anymore. I always felt that software was such a burden to work with. Now I can just hook up phone to my laptop, open up mass storage and drop files in a folder and bam, got my music and videos playing. I can create and play my own customized ring tones too without problems.
I don't want to forget the basics: it feels great in my hand, the phone quality is great with no drop calls. Browsing speeds are incredibly fast (at least compared to my iphone 3g), and the super amoled is very nice to look at! True multi-tasking as well!
My cons:
1.) Can't get my university email set up. If anyone knows how to do this that would save me a trip to the university tech guys.
2.) Can't sync my facebook pics to my contacts. If anyone knows how to do this without getting error messages, it would also be greatly appreciated.
3.) the battery itself seems to be doing okay. What I am really having a problem with is how damn long it takes to charge the phone! Is anyone else experiencing long recharge times? I feel like it takes almost an hour just to charge 10% on this phone (just a guess, i haven't really timed it yet).
4.) The world clock sucks. Is there anyway to type in a specific city and not have to use a preloaded city in that same time zone?
There might be more things that show up with time that I like or don't like about this phone but at this point, I'm very happy I made the switch.
