I seriously hate the Galaxy S for it's GPS. I mean really hate. Although having improved the fixing with newer firmwares, it is still atrocious while navigating: skipping all over the place and giving wrong directions and above certain speeds (around 140-160Km/h) loses gps altogether.
For me its basically unusable and I was very close to throwing it out of my car window a lot of the time!
Luckily I still had my Holux GPSlim 236 from the times were integrated GPS was still a myth and alongside Bluetooth GPS Provider it works like a charm. Pinpoint accuracy all the time. Finally my Galaxy S feels like my Milestone did GPS-wise.
Of course it is not practical to carry around a GPS receiver all the time, but for those reliant on in-car navigation it's a good solution as gps receivers should be pretty cheap now.
For anyone interested I recommend a Sirf based chip as the app support NMEA.

Any chance of posting a sample Mytrack recording?

haha and that one is over 5 years old!

And ironically it is so much better albeit much larger than the GPS in the brand new Galaxy S.
I will try to record my next trip when I use the GPS with myTrack.
On the trip I recently tested the Holux on it was 99% accurate almost all of the time. No wrong location, no location skipping and it even registered correctly when I was stopping at an intersection.

Both. As i understand it, the app will only work with the bluetooth gps as long as the Galaxy can 'see' the gps unit via bluetooth, which it can't.

Why not? Maybe he was on a derestricted toll road like the Nurburgring for example, or he was simply on the German Autobahn, where there's plenty of place where there is no speed limit. Or you're suggesting that you shouldn't drive at that speed anyway?

The only problem I see with the SGS GPS (maybe other people have different problems) is that it just drops all the Satellite locks for some unexplained reason. Once it loses lock it usually can't regain it because you're moving or whatever. When it is locked though I get very good accuracy and it's quick to update. Funny thing is you can watch it in GPS test. I could have GPS test open with 11 satellites in view, and 7 or 8 locked with 20-40+ SNR and then all of a sudden the signals are dropped while the satellites are still clearly in view.
Anyway...I hope Froyo fixes it for me. It's probably different for everyone else.

I tried this guide and it worked for me:
1. The firsts step is to dial the following codes on your Samsung Galaxy S:
* *#*#1472365#*#* If you are running Android 2.1 Eclair.
* *#*#3214789650#*#* If you have updated to Android 2.2 Froyo.
2. once you finish dialing the codes mentioned above, you will have a LbsTestMode screen on your phone with several option.
3. Now tap on Application Setting.
4. In Application Settings, click on Operations Mode followed by selecting Standalone.
5. Once you are back on Application Settings, tap on Start Mode and click Hot Start on the pop-up.
6. Now select GPS Plus and put it on by clicking the ON radio button.
7. Once done, click on SkyHook and also change it’s value to ON.
8. Now go back to the first screen and tap on SUPL / CP Settings.
9. Once you have done this, tap on Server FQDN Type followed by clicking on AUTO Config.
Once you are through all this hardwork, it’s time to reboot your handset. Once your Galaxy S boots, launch Google Maps and you will get the fix within 5 to 10 seconds. Enjoy GPSing!

Unbelievable!
Even if I had all of the other settings allready as described, my gps was unstable (gps test). The only thing I changed was the FQDN (which was something like supl.google.com) and now it is stable and more accurate. It doesn't continously change the sats used for fix.
I can assure you it worked for me!

For gingerbread you can use AngryGPS I guess.

i would not recommend using such app(s)
they will not make SGS1 JVR gps any better

from what ive spotted my gps was working normaly
but after last time it landed on the ground it takes a bit longer to obtain fix and stay on it
probably will have to dissasemble my unit and check all the connections
it is not a big change but still noticable

GPSrestore Samsung APP FIXED my GPS

From day ONE my GPS has not worked. After spending endless hours on "fixes", phone resets, hacks AND 4 new phones, FINALLY it appears that a solution has been found that really works.
The GPS was taking minutes to lock before I updated to stock froyo and after updating to froyo the GPS became totally useless until yesterday when I download "GPSrestore Samsung" app from the market and ran it.
Instantantly my GPS/Maps/GPS test obtained a GPS lock within 5 seconds and im also getting a fix in my office building (near the window) within 20 seconds. No one in the office has been able to get a fix at this window location
I'm not sure what GPSrestore does, but it finally fixed a painfull bug.

I am not trying to piss in your wheaties but you might want to wait a couple of days and see if it holds up. Or use it on a road trip. It worked for me for a day or 2. Now I have to run that app about every day or mastersgps fix to get the sat to lock. Better than nothing I guess

I usually run the restore app every time I use navigation. It does fix it, but goes away after a couple days.

Do the hardware fix if you think you're up to it. The GPSRestore app only helps temporarily, it wont be long until its unreliable again.

Samsung gps restore works because it forces our phones to use standalone gps without ms assist feature to get triangulated location using network data.
This in my opinion is not a fix its a workaround and it only fixes half the problem. It helps us get a lock but the accuracy is still a major issue

So bummed, I can't get this working
My problem is that I have to run GPSRestore before every Nav. But it usually takes 4 or 5 tries. It usually happens after 10-15 minutes of driving. Its so frustrating. I am tempted to try the hardware fix but I'm a total tard when it comes to doing things with my hands. Help! Anyone out there willing to earn a few bucks if I send you my phone and have you do this for me?

Same here, gps restore only works the first couple of times & then its like you did anything to fix it.

Sorry to burst your bubble, but the LG 2x is the worst hardware I have owned ever. Everything is unreliable and randomly stops working, including cell reception. GPS is flaky on it as well, as is the camera - the cover of the camera causes glare, needs the back to be taken off if you want good looking photos.
I will buy Samsung every time over a LG. Yes GPS on its own is weak but with A-GPS Sammy's lock instantly.

It's really easy and only takes about 20 minutes. Follow the guide that KWKSLVR posted and you'll almost have the average GPS we Vibrant owners have been pining for over the last couple years, heh.
Something to think about on top of the just bending the copper tab in case you try hardware fix... I snipped the end off of one of the ends of a coax cable I had lying around and used some tweasers to wedge it under the copper tab after it's bent up; just as a little reassurance that the tab doesn't bend too much and lose contact with the back cover's copper connectors.
I take no responsibility if you aren't gentle and break something though, heh

Taking Samsung to consumer court

Hi,
As we all know the Galaxy SL GPS is piece of crap, I have contacted Samsung support many times but their technical team does not know the difference between GPS and GPRS. They have no answer to how to fix the problem (at least Indian support team) or there is no fix. Anyways I am now highly frustrated with the GPS on the phone and with their customer support.
I have not rooted my phone, the firmware on the phone is DDKB2 (not updating it yet or rooting the phone because it will affect the warranty) latest available from Kies.
My question is to all Galaxy SL users what is the max number of satellites has your phone ever locked. (irrespective of the firmware version) For me the max was 4. It took 5 mins to reach this figure under open sky on this phone while Xperia arc and HTC wildfire were able to lock 20 satellites from the same location in seconds.
Is the GPS on phone really a piece of sh1t ? Just confirm this and I am prepared to sue Samsung in consumer court over this.
Adding to this, while traveling in a vehicle the other two phones (mentioned above) were showing realtime progress of the vehicle on the road, whereas Galaxy SL was highly inaccurate and even the wrong position shown was not updated constantly.
Edit : Please use 'Gps Test' or similar apps to check.
This is my best result so far.

That's why I am curious to know that after all the proposed fixes how much improvement is there, if I install 2.3.4 the unofficial way how much will be the improvement. i have read in some threads that there is no software fix and users are hardware modding.

XXKB3 solved the problem for me. My GPS locked in seconds now.

dude take them to court ,gps on this phone really suks ,atleat after this they will send quality products to indian market

The problem is only in the software. Hardware is very good. I have XXKB3:
1. With the cold start on open air (no clouds, but under the tries and near buildings) I take signals of 3 satellites after 2-3 seconds
2. after 5 seconds It locks
3. After ~10 seconds I see about 8 satellites. (6 with good signal)
Before I had Nokia 5800. It takes several minutes to lock. And if I was driving car it takes more and more time (it would be better to stop, wait for a lock and drive then).

How many satellites?
For a moving source you need more satellites as the connection with every satellite is not constant, how does the device behave when in a moving vehicle?

I was driving in the storm (very big storm, in my city it took out tries with its roots from the ground and it was very cloudy) for more then 300km. Sometimes I was driving with 140km/h. No lost locking at all. But before I used GPS Aids to take latest LTO data, and I had internet connection for all my way (to take map and so on).
It's really good device for me and it suits me well. With my native XEKB1 I was not tested GPS because I reflash my phone after 2 days of playing with it.

XXKB3 solves the GPS problems many ppl have mentioned.
I do not know how many satellites it uses/doesn't, I just know it works (and thats all that matters).

Bro, taking them to court will be a waste of your time as you know the indian courts and justice system.
My advise is, try rooting it and flash different rom which meets your gps needs.

Filing a case in consumer court is very easy, I will go to samsung service centre this weekend for last time, if they still cant help then I will go ahead with original plan.

Try this: use FasterFix (requires root) to set the ntp server nearest to you, then use GPS Aids (requires root aswell) to download and inject the XTRA data. Once you 've done that your GPS "should" be able to see enough satellites to get a good lock.

To those who are getting v.quick fixes with the newer European firmwares and other miscellaneous fix. How does it fare when doing voice navigation?
For me , I get v.quick locks (after some hacks..6-10 satellites in view and all), but still not reliable during voice navigation, loses signal in the car. So, I believe that is a h/w issue, but then, I guess many phones will be having this issue to a certain extent.. (not able to follow you properly when travelling in a car with windows closed? .. iPhone 4 which I have played around with ,definitely does the tracking v.well)..

dude.. just check out dis thread b4 u go 2 court...

Correction
I'll just make a correction to my prev post... Instead of following that link in the post try these things and ya i have personally tried this settings & it worked
i havn't done any rooting or upgrading or anythin, its just the basic DDKB2. I had to reset my phone to factory settings due to a different problem. SO when i tried using the gps after reset there comes the same prob again
First thing i tried was that link, but it doesnt seem to work very well then i followed these steps...
1. Download the app "GPS AIDS V2" from android market (free version is more than enough)
2. Turn off your internet & gps & go to codes/tools in GPS AIDS
3. Select GPS Test >Application settings & make the following changes
Change Operation mode to "MS Assisted"
Change Accuracy to 100
4. Now turn on gps & internet, Go back to GPS AIDS Select GPS Status
Now it will start locking satellites
Using this method i was able to get a lock with 10 satellites in about 15-20 seconds & was getting an accuracy of 5-10 meters
And one more thing.. i am not a big fan of samsung.. Right now i am facing some other issues with this stupid device... Anyways just trying to help..

I was having the same problem as you guys, but all I did was change the ntp server to india (using gps aids) and setting mode under GPS settings to "ms-based" instead of 'standalone'...
Actually the GPS on this phone is really quite weak, I get good quick locks and signal strength but indoors it struggles under a tiled roof whereas my xperia x10 used to do it great indoors too! Oh and the applying pressure to a certain point trick actually does work! Try it out...

[Q] Is there a way to fix my GPS?

Hello all!
My Nexus 4's GPS is simply not locking. Is this a problem for anyone else? Is there Amy way to fix this?
Yes, I'm indoors, but so is my sprint s3 and it gets an instant and accurate lock. I tried a hard reset, but that didn't work.

Is anyone experiencing any GPS problems?

nope, GPS works out of the box here. have you tried testing with GPS test?

In order for gps to work properly it needs to be able to see the satellites. Which means a clear view of the sky / outside
That is the reason why GPS signal is shaky in large cities and doesn't work in tunnels period. Stating that your GPS is broken because it doesn't get a lock inside is just frankly silly.

I would agree that it sounds silly but I also understand and agree with his point. My EVO LTE on Sprint locks indoors in NYC within a matter of seconds but my Nexus 4 on T-Mobile pre-paid never locks in exactly the same spot. Outside in the open it is fine and locks quickly so I can't say the GPS is broken but it's certainly not as strong as my EVO LTE.

same here. on T-Mobile. Verizon s3 gets an instant and accurate lock

My GPS locks very quickly, but after about 30 minutes in Navigation, it drops, and I have to turn off GPS (or exit and restart the Nav app), and turn it back on to reacquire satellite lock.

Sounds like you need a replacement, I'm blown away by how fast my N4 locks especially compared to my sensation.

Lol sry super late to respond. When y'all say you get an instant lock, do you mean as soon as you open up maps it find you, or does it find you like 15 seconds later? Navigation wasn't as smooth as I had hoped. Yesterday when using it it lagged behind throughout the whole trip... I'd imagine if I sent the device in to Google it would take foooorever.

I'm also experiencing slow locks.

I9505 Stock MH8, No GPS lock?

If I use just the Sats can't get a lock.
Running GPS toolbox shows 24 sats but I can only ever get a lock on a single sat. My i9300 shows 16 sats locked on 12 in same app.
Left i9505 with app running overnight on window no lock.
It looks like either the signal strength is too low or it 'locks' on one sat then can't move onto next.
Tried resets and reflash no joy.
All I get is this.

Thanks for the idea but I've already tried GPS Test and it never finds a sat and as I've done multiple reflashes and resets I've probably done at least half a dozen reboots.
To be honest I find GPS Toolbox better then GPS test anyway as you get a lot more info on what sats are live.

Yes, but did you try updating AGPS data? If you can do it from GPS Toolbox, do it. As long as you try that too. Did you also flash the MH8 modem with the ROM?

Yes I've updated AGPS data, there's a facility to do it within GPS toolbox and you can see in the piccy above it's 0 (zero) hours since the last update i.e. It was updated within the last hour.
The MH8 flash was done by Sammie OTA, the Baseband is MH8.

Weird. Tried reflashing the modem with Odin?
Other than that I'd try a factory reset or a completely new flash of MH8. No other ideas, sadly.

As I said in the first post I've tried multiple reflashes, does anyone know of there's a service menu option such as hardware default reset?
The only thing I can think of is the modem (which I think the GPS interfaces through?) isn't getting reset properly and that'll fix it, else it's off for a hardware check.

Could you solve it?

Same problem
I'm using different modem but I have the same problem.
I'm using Gps Data to show satellites. At first it shows around 20 satellites after that the amount starts to drop to 9-11 satellites.
It can always get one fix for a moment to some satellite (usually 71, 72 what I have been following today) strength is 40-41 but it loses it in 5-10 seconds. At the same time it also always shows strength 30 to three other satellites.
After it has that one fix and 3 others with signal no fix it drops them all and looks for new ones and does the same thing after a while: one fix again to 7X number and 3 signals no fix.
Interestingly enough the one fix it gets seems to be russian satellite and the 3 others are american... still, I don't think that's the problem or could it be?
Before I had problems with gps and 3g too (only got 2g) so I sent the phone to repairs. Now 3g works and the gps signal strength got to that 30-40 to at least some satellites. Before warranty repair it was around 2-4 satellites and signal was only 3-10 and never fix.
They told me they had changed the motherboard of the phone other than that I don't know what was the problem since they spoke only Chinese. I'm in Shanghai btw... so 3g got fixed but gps still no lock.
After repair I have tried 3 different modems and unrooted stocks. Same problem with all modems and firmwares, same satellites, same strengths.
My friends Sgs 3 and Sgs 4 have no problems. I also didn't have any problem at the first.
Did you get your phone fixed somehow or was there HW repair ?
