I have a 6 month old Samsung Captivate i897.

Here recently I find that after the phone has been on for several days I can't get the GPS to work properly. Here's what happens.

I try to look at a map and see what shows as to where I am, or especially I try to check in on Facebook. The GPS icon spins and spins and I eventually get a "can't determine location" message. This happens even when I am outside and have a clear view of where the satellites are.

But - I have found that if I power the phone off and then boot it up again I can immediately use the GPS function as intended, especially with Facebook.

It will work for a few days but then I have to power down and back on tho get it to work again.

Anyone have any ideas on what's going on here?
