    I need to decide whether to send my phone back as faulty for a replacement or whether I should just give up. I need to check if anybody else has a working GPS.

    Can you do me a real big favour? Can you download "GPS Test" from Chartcross Limited (from the Market).

    It's a pretty cool app and looks pretty nice on the screen in any event.

    Here is a comparison with a HTC Desire:

    As you can see, the HTC Desire has more satellites but less signal. But it means it is capable of a better signal lock and more accuracy.

    Signal lock is so up and down on my Galaxy S. It will randomly lose connection and gain connection, losing connection to satellites with high signal strength and not seeing them anymore, than gaining connection with low signal strength. It refuses to use certain satellites and refuses to use anything with a low signal strength.

    So unlike my friends HTC Desire, I don't see any orange or red on the signal meter.

    Just walking around the block, my GPS bounces between two and give satellites, resetting its satellite list, not locking onto satellites, ignorning higher signal strengths then locking onto low signal strength of "20" and then losing them.

    Right now, my phone is bouncing between 357.6 and 98.4 feet accuracy, seeing seven satellites but using none, even though I have four satellites with an SnR of more than 22. Even the magnetic compass is bouncing around all over the place. My phone is just sitting there on the desk (by a window) doing nothing, and signals are so far up and down it's ridiculous.

    So the question is, if you install this app and pop outside, for a few minutes, what do you get?

    Do you get a lot of satellites? More than 4? Do signal strengths stabilise? Do you only get yellow and green results like me, or do you get all manner of red and orange satellite signal strengths?

    Looking forward to your quick posts.

    Here are my results on a two year old HTC Dream G1 in Los Angeles:

    Inside my office 9 Sats in view 9 Sats in use.

    Outside 11 Sats in view 11 Sats in use.
    9.8 ft. accuracy.
    Mostly yellow signal.
    Does bounce around alot but I think that is to be expected.

    Hope this helps.

    I've just used run.gps to track my last two commutes to work to see how the accuracy is, looks fine to me. Can't complain with the GPS performance so far.
