To be sure is working you need to use something like GPS Test. If you just run maps it will use cell towers and wifi too. So may look like its working better than it really is.

Although for every one of us with a problem, there seems to be another with GPS working fine.

Agree.... The GPSTest app is great in what it does...... just a shame the Galaxy S performs nowhere near as good as my HD2 and the older HD.

mine is working great. It finds me in no time. The navigation is a lot smoother than my Tomtom XL Live, I don't like the voice though. Can this be changed at all? Can't find an option to do this....

Actually, from the spec's it does look like one of ours, namely the InCrystal 20751, with GPS/BT3/FM support. So anything I did learn I wouldnt be able to share anyway.

Thanks.

Will do as soon as i manage to get such a lock again.

It's not 22, the Samsung Galaxy S won't lock onto anything of 20 SnR or below unlike HTC Desire/G1 etc.

If you see a grey bar in "GPS Test", that is not a lock on, that is just "I can see this satellite".

The current XXJF3 software seems intent on only using upto 8 satellites, even though you may see 11 all with a good signal, you will only ever use 8.

I wonder if this is half of the problem, it cannot use all the satellites it sees, so when there's a bad signal from a couple in one direction, you lose your lock and it has to try to work frantically to establish a lock elsewhere.

Does XXJF5 allow a lock to more than 8 satellites? Does it open up use to Signal Strength of 20 or below?

Not on my phone. The GPS is still useless.

For those whose GPS is working fine, we need to know I think what your baseband version is, and whether you rebooted your phone prior?

I seem to get a better signal after a reboot. Better, but not perfect.

I must admit as well, you need to walk around the block and see what happens.

Although I think those of us with GPS problems will see problems when stationery, sometimes, you do get a strong lock on. But walk around a bit, and the thing gets confused. If you take a look at the Sky Map or Satellite Position maps in GPS Test et al, you will the direction "North" bounce around all over the place.

Hmm, this is interesting. Have just tried it again, and now it can see 8 and locks to 8, but the weather has changed in the past couple of hours as the temperature has dropped and its clouded over, so from I have just seen, I wonder if atmospherics have something to do with it.

I too am facing some problem with getting a proper GPS lockon. Even after finding an open spot and spending couple of minutes searching for my destination, the phone still encounters problem getting a proper lockon. Sometimes it took a restart of the navigation app and turning off and on of the GPS receiver before it can finally get proper lock on the satellites.

Does it got anything to do with the phone design or firmware issue?
