Those with a bone to pick regarding the handling of GPS support on the Samsung Captivate should get some relief in the coming weeks, as Samsung and AT&T have announced an over-the-air update for the handset that should corral the hit or miss location functionality plaguing the device. The update will also bring other enhancements such as improved media scanning time, the full version of Quickoffice, and Microsoft Exchange 2003 policy support will be addressed.
When the update is ready for you to receive you will get a notification on your device to download and install. Of course, this should take a couple weeks to completely roll out to every device. You can always try the old Settings>About Phone>System Updates trick to try to force the update.
While it is no guarantee, with the Fascinate receiving a similar update in the near future we expect the GPS issues on all versions of the Galaxy S will be dealt with shortly, even if we still have to wait a couple more months for Froyo.
