Did the latest firmware fix the GPS issue?

dakine · Jul 9, 2010

I can't seem to find a straight answer to this so I'm starting a new thread.

With the JF3 firmware the GPS on my 2 phones is often not very accurate or completely loses it's position under what could be considered good conditions for a gps reciever.

Did the new firmware fix this problem?

Please only reply if you actually noticed the problem and can compare it with the new firmware.

Using GPS test is the phone now able to use signals with an snr of lower than 22?

No, it refuses to use GPS with snr under 22, as long as you don't locked them when they were higher. In that case it keeps them downto snr 17, and then drops them.

No and no....

Well that sucks, let's hope it's not a hardware problem

In contrast... I just flashed G3 and my GPS now locks in about 5 seconds.

It doesn't lock below 22... But for me it now doesn't need to.

Mine also locks in a few seconds, but it loses the lock again after a while. Then it locks again, the lock disappear, and so on. Completely useless as navigator.

This is quite worrying, because it suggests more than just a firmware problem.

To those who have flashed and it hasn't worked, some suggest flashing using the repartition option.

But this experience is why I don't want to flash my phone. If there's a hardware error, I can't rightly be taking it back.

Might get a HTC Desire and put the extra few quid up towards a 32 Gig memory card.

on further testing... My phone does use satellites of 19 to 22... But only if it is connected to less than 8 other satellites.

And I don't seem to have a disconnect issue.

Yes the problem isnt that it wont connect but that the thing often thinks you are on an offramp or a road next to the highway you are travelling on because the sinal is too weak/inaccurate. I tested this with 3 different nav programs and get the same result.

Let me get this straight, using GPS Test, you do see orange satellites through regular use?

This is all beginning to make sense now.

Unlike HTC which seems to use a GPS chip that is capable of 12 Satellite fixes, Samsung is using a GPS chip that can only lock onto 8.

I would think therefore that what it is trying to do, is to select the 8 strongest satellite signals which means it's already at a disadvantage, because as soon as you walk behind a tall building, it has to work to try and find and lock onto others. But when you walk past the building it goes back to the other satellites.

This probably explains why everything is jumping around. Because it's not using the weaker satellites in the distance until its too late.

Maybe you guys have the problem of "you hold it wrong"

when I put the phone's face upward, I got only 2-3 satelline locked
stick my phone up => 10 satellites locked and most of them are green
cheers

No - I have installed JG3 and still have the same problems. GPS is practically useless.

Its nice I still have my HTC touc hd - I get a pinpoint lock immediatelly.

Lord Style · Jul 10, 2010

Have you tried to use an external bluetooth GPS device ?

dakine · Jul 10, 2010

Don't think it's possible to use an external gps with android. How do you tell the os or app to use the external one instead?

JG3 seems a lot better for me. Still not perfect, but better than previous versions were I only lost a GPS a couple of times opposed to ALL the damn time !

dakine · Jul 10, 2010

Well guess I just need to flash my phone and try it myself. I wish Samsung would just release an official update already.

*#*#1472365#*#* gps test

Type this in using the keypad and then find skyhook and turn it on. This will help your GPS locate quicker and stay locked.

I can get satallites in my living room!

*do not adjust anything else*

I got the code of this website.

Why would i lie? I've had my phone like 2 days and i was sick of getting no gps so i went on the hunt for a fix and there it was.

Google skyhook if you wish.

dakine · Jul 10, 2010

Anyone else tried playing with the accuracy value in that menu? It seems like it has an effect on locking satellites but I'm not sure.

Did the latest firmware fix the GPS issue?
