I just went out and tested it. I did not enable GPS, just used the location from the nearest tower, and found it to be very accurate and smooth. I was going to check for the functionality with the GPS, but the mosquito population drove me indoors.![]()
The stars just jerk all over the place--it's completely unusable. Is it happening to all Captivate users, and if so, what's the problem? I don't think we can blame this one on GPS can we?
I seem to have a different problem. The app seems to be off by about 90 degrees from the true position in the sky. For example, it should show the sun (as judging by moving the phone around and finding a location for the planets, moon and sun). But when I hold the phone directly between myself and the big glowing yellow ball, the app does not show the sun... If I turn the phone so it is aimed in another random direction I can find the sun on the display, but it obviously isn't pointing in the right direction.
Anyone got a suggestion?
Mine is only accurate if I point the camera lense at the object. It took me a while to figure this out. I do notice however that the app tends be behind time-wise by an hour or so. I wonder if it doesn't take into account DST.
-- but when I checked my location, Skymap was set to think I was in Pisa, not Texas. Changed to the correct location, and suddenly everything lines up. 
Am I missing something? Do we have to calibrate the compass? How do you access it?
i dont even know how it works so i cant say whether or not its unusable. it just looks like a novelty you can show off to people anyway.
