I might be on to something for the GPS issue.

Well like everyone I had the GPS issue and it was frustrating. I do run an app killer and I always notice many apps (especially the preloaded ones) Keep launching themselves. It got rather irritating. Specifically Telenav.
I noticed with Telenav my GPS would be very flaky. Once I got "killed" it the gps seemed to improve. I thought to myself maybe I'm just being paranoid.
Did a bit of research and found an app called "Start UP Auditor" which completely kills an app and restricts it from every starting up again. My gps seems to be working much better now.
I drove a few miles and on the Verrazano Bridge here in NY and the GPS was super percise. When I was at the end of the block it was at the end of the block as well at the same time. Not like it was before.
Now I can launch google maps and it will find me exactly in front of my house and not 200 feet away.
Takes a solid minute to lock on. Not more but not less unfortunately. So there still is a bit of a problem but for me at least it has exponentially gotten better. Versus it not even locking on previously.
I think I might be on to something. I cannot give all credit to me because I saw on a Tmobile forum someone say that they think the problem might be with the self launching apps so that's where I started to draw conclusions.
EDIT: Scratch that one min thing. It seriously just now took me 10 seconds to lock on and the GPS to start talking to tell me where to turn inside my house. Issue fixed?

I completly removed TeleNav and I still have GPS issues... It is not any software causing this problem. It is a Hardware / Firmware / Driver issue.

Same here, one of the first things I did after rooting was remove all the bloatware, and Telenav was one of them.

Hmmm... Interesting.
My GPS issues seem to have disappeared after killing Telenav.
This just takes me back to the drawing board once more. I just do not understand...
I would like to see others responses. Does there happen to be vibrants with different firmwares?

So what happened to me?
Was it some magical stroke of luck?

Wow.
Initially, disabling TeleNav gave me a significant improvement in GPS performance. Indoors, I went from having 50-60ft. of accuracy (with multiple locks), to 12-15ft. of accuracy with a single lock. Initial accuracy was in the upper 40s, but quickly dropped to the highest accuracy I've seen with the device (the 12-15ft. figure) - indoor or outdoor - within a minute. Crazy.
Outdoor, on a perfectly clear sky, the best I've achieved was previously 25ft. of accuracy.
I rebooted (the phone froze, wheee!), with TeleNav still selected as disabled, and now, I'm only getting 30-52ft. of accuracy with a single lock. This took about two minutes to come down from 170ft. or so.
GPS settings have been switched to 'Automatic', from the stock supl server, for all of these tests.
Maps still shows me in Issaquah, initially (incorrect data), but quickly updates my position my exact location (within a few seconds). Previously, Maps would take at least a half hour to place me in even the correct city! Margin of Error: ~50ft. or so (shows me on the street, rather than on my property), within seconds.
Compass, as expected: still totally ****ing broken and ****ty.
I can confirm that - besides not being able to lock onto more than a single sat - I'm seeing drastic improvements. Thanks for pointing this out.
Still, I'm not sure the improvement will be enough to convince me to hang onto the device while we wait to hear from Samsung. :/

Yea like I said in the OP the fix is better but there definitely is a problem that needs to be addressed. That might be either hardware or firmware, All thats left is to wait for sammy to fix it up. However my GPS performance for my needs is more than exceptional.

I have noticed that while running GPStest, Google Maps starts to work. Something is wrong with the API.

If anyone is getting black screen freeze ups, disabling GPS will clear that right up.

And, we're back to square one. So much for that.
Location services can no longer locate me, and show that I'm in a neighboring city. Nothing I adjust fixes this for more than a short period of time.
Oh, Samsung...

It seems to me that it is definitely a software problem. I don't think the hardware is bad. (The gps chip?)

I drove for miles and had nothing. Though if I am not using GPS I always turn it off to conserve battery.

I wonder if they can't even find the issue yet. It will probably be fix in the 2.2 update.

I removed TelNav within 4days of owning my phone and it really for me hasn't changed a thing.
What helped me was turning off the wireless location feature. From what I noticed it looks for your location based off the cell towers first then it looks for your location via GPS. If its slow to find you via wireless then well its slow to find you via GPS too.

I didn't really tried the GPS when I saw the threads saying there was a problem with it and I read somewhere about "how to fix it" so I applied the fix before even using the GPS before, so I have no clue if I had problems or not, but after the fix, the GPS locks in about 10 to 15 seconds and gest my location on the spot, even indoors.
just change the GPS settings to google servers

Directly after rebooting my gps/navigation seems to work much better.
To make it more clear... I'll be using my phone throughout the day and then i'll try to use navigation. Usually it will just keep trying to find the route but it never actually finds it. I'll reboot the phone and it'll find my location and the route in <10 seconds.

I believe the wifi and GPS share the same antenna. Anyone know which antennas do what for sure?

Our cellular antenna is at the bottom under the bump. The one at the top next to the antenna port does the rest.

Thanks for this tip, I hadn't caught this in the other GPS threads.

I ran and used My Tracks but forgot to turn on GPS. When I tried nav it could not get a fix until I restarted. Next time I'll try killing conflicting apps.

I just deleted the Tel-Nav app and now my GPS locks on in about 10 seconds and is dead on accurate. I even drove 165 miles today and never dropped a GPS signal. I could never do that before.

Does anyone know why the times are off one the gps sensors? My local time is 10:51, but gps test has it as 18:51 that is about 8 hours off.

[settings]Fixed GPS with Cognition V2

Hey guys, Ive been having lots of issues with the gps actually locking on my phone, i know some of you have mixed results, but i was playing around with some settings and finally got a lock inside with 8 sats!
Below are the settings needed.
Getting into LBStest mode:
Then select SUPL/CP settings:
Server FQDN Type
Auto Config
Server: (This is the important one)
h-slp.mnc410.mcc310.pub.3gpp
Server port
7275
SUPL Secure Socket
Off
AGPS Mode
SUPL
I tried the same settings manually on my wifes phone with cognition 2.0 and it didnt work and the server port was a different number. I tried copying my settings over but it didnt work.
It looks like you need DG's cog v2.1
This worked great for me, hopefully it may help you guys out!
EDIT: picture is sitting on my couch 5 feet from a window!
Ultravorx

I tried those same settings and saw 8-10 satellites too standing still.
Now set your navigation and take it for a test drive. It's still useless. (for me anyway).

i went from 5, to 8... lol so it was a small improvement.

I suggest you look at http://forum.xda-developers.com/showpost.php?p=8264844&postcount=1
SUPL servers provide ephemeris/almanac data which is usually good for 7 days. Changing wouldn't do much. It's usually a one shot thing. By default, the hardware GPS needs to get this information from the satellites themselves which good GPS units do in 45 seconds (SIRFIII) but I've seen bad ones take up to 30 minutes.

Same here.

It seems we need to start a thread where everyone posts their Lbstestmode settings and results to try and narrow down ONCE and FOR ALL which settings are the best.
More specifically, which settings are the best NOT ONLY for getting a GPS lock standing still in your home/apartment/office/wherever but most importantly while using Google Nav WHILE DRIVING!
In my opinion, getting a lock and going nuts over how many satellites your phone sees while standing still is pretty useless. I use my GPS primarily for navigation driving around town.
I've tried three completely different lbstestmode settings posted by different people in this forum, as well as the default Cognition 2.1 settings. All of them lock while driving, then lose the lock shortly after.

The issue is, at least for me and others as I have been reading, is that after the OTA update you can't get anymore into the Lbstestmode config with the dialstring.... Is there any other way to open/config that? I know this is not really Cognition related, since I guess with it you are still able to get in... probably will try it....

You can if you use LauncherPro. There's a walkthrough on here about it...but you basically create a homescreen shortcut to an activity and select LBSTestMode.

When you guys flashed the jh7 update, did you tibu your system settings and apps, or apps only? I did apps only and it fixed my GPS. I drove around, and even didn't follow the route, and it still found me consistently.

If you do some interweb reading you will see that most of the other phone manufacturers have an agps server. For the Deathstar it is: h-slp.mnc410.mcc310.pub.3gpp. In an almost universal rejection most are switched to a nokia server or to google's servers claiming faster locks and improved location awareness.

Meh - I've tried them all - can get GPS to work for a short period of time, then the device seems to die. I really think this is a hardware issue.

I think it is Hardware too. Only because I really have never seen any issues with my GPS running many different roms. I am a Field Technician so I am always driving around. I have been using my GPS when I go from site to site to see if I can find any real issues. It has stuttered from time to time, but not real big issues. Seems to skip for a second or two and then gets rigth back on track. Now each site isn't that far from each other about 10 to 20 miles so it may be that I haven't had a long enough trip to have any issues. I did go on one 100 mile trip the other day and it never quit on my. I am going on a 300 mile trip Sunday so will test it out the whole way and see what happens.

Thanks! That did the trick.... I see now that it still has the same values I had put in before AT&T's OTA update.... so I guess that wasn't touched by the update... makes me wonder... today I had way better reception and was actually able to drive from work to home without the signal dropping not even once... Only thing I did last evening was clear out all GPS data... so, now still on OTA JH7 and wondering if I should or not change that...

I have been thinking this too. Had gps issues with my first captivate, returned it because it kept shutting off. On my second one, no issues at all.

GPS Plus
Those having issues while driving, could you disable GPS Plus and post your results?
My settings:
Application Settings:
Session Type: Tracking
Test Mode: S/W Test
Operation Mode:MS Based
Start Mode: Hot Start
GPS Plus: Off
Dyn accuracy: On
Accuracy: 50
Use SkyHook: Off
Use PC Tool: Off
SUPL / CP Settings
ServerFQDN Type: Custom Config
Server: supl.nokia.com
Server Port: 7275
SUPL Secure Socket: Off
AGPS Mode: SUPL
With these settings I've been having great results, but I can only test in maps.
There is no navigation in Guatemala

Yet another settings to try for GPS Fix...

I have always had issues with my GPS,,, but after applying this settings , I always get a Lock in less than 30 seconds,, and navigation is spot on. Accuracy is less 20ft..
Go to lbstest, go to SUPL/CP Settings and change Server FQDN Type to AutoConfig, in Application Settings , change Operation Mode to MS Assisted.,,,
thats it, you dont even need to restart the phone... go to GPS Position Test and watch your birds coming up and locking...,
Even after a phone restart still getting locks in less than 30 sec.

Stop messing with your gps settigns.
Not trying to be rude, but everyone with GPS issues are probably people who keep tinkering and messing around with LbsTestMode.
Remember when the Vibrant first came out, during the summer, and that stupid fake thread on xda spread like a virus claiming "GPS FIX." THAT WAS NO GPS FIX. It made problems worse.
Suggestion for people. STOP MESSING WITH THE GPS SETTINGS, LEAVE IT ALONE.
IF you have messed with your GPS settings do the following.
1) Go to android market
2) Download "GPSRestore" by Samsung Mobile
3) Run that application.
4) NEVER TOUCH YOUR GPS SETTINGS EVER AGAIN
5) NEVER LISTEN TO SOMEONE WHO CLAIMS THEY HAVE A GPS FIX ON XDA.

and guess what that little app they have is garbage. i went outside in a field and did ran the app and i couldn't even get a sat lock at all. ran it 3 times couldn't get any locks. ill go back to messing with the setting seeing as they both don't work.

i lol'd.
but really, whenever i changed those settings it made things worse. i installed and ran that app and it didn't affect anything (my gps is one of those magical, rare ones that work evidently. lol). i hadn't changed those settings, but i'm running axura so i don't know if it has modified settings to begin with. well, that was after the app failed twice. then i realized my gps was off and it ran fine.

The only thing I changed in lbs mode where those 2 settings... and btw that app from Sammy did not worked for me at all. My GPS never workded as it should since day one... I never played with lbstest until know that I had too.. cuz I new my GPS was not bad since it worked perfectly using Macnut R10, so I started looking for settings to make my GPS to work with other roms... Right now I'm running the Stock JK6 and if I run the Sammy GPSRestore app I can not get a fix in less than 5 minutes with 50meters accuracy. But with those 2 changes in lbstest... I got a working and reliable GPS. That's why I wanted to share what it worked for me, cuz I know that there are other Vibrant owners with similar problems and using different carriers like me who is using the Vibrant on AT&T.

I don't understand why, after running it I geta lock in less than 3 mins. Use to be 15.

Here's the best fix:
1.) Install Nero 4.1
2.) Leave it alone.
The end.
If that doesnt work:
1.) Install Nero 4.1
2.) Do the hardware fix
3.) Leave it alone.
The end.

my solution: get a new phone once a suitable 4" replacement comes out on t-mobile.

it works!
this by far is the best solution!
I get 10m accuracy now whereas i used to get 1200m before...

Let me try it a bit more, but it seems it works!

i got 10 satellites in 5 seconds, then they all started connecting and now my accuracy is 12 meters???

I think your all connected to wifi, maybe thats why your getting good locks. Disable it and try again.

I was out walking my dog this morning (no wifi) and while yes I was in a clearing, I turned on GPS Status for the first time since installing the new rom so it came up with the default html page explaining GPS Status, but I read it before so I closed it immediately and was already locked onto 8/11 birds. 2 seconds maybe. 7m accuracy.
On the flip side when I first got my phone I tried to use it as a GPS to navigate and drove around for 30 minutes without ever locking onto a single bird.
I understand and do believe there is a hardware problem with many Vibrants however I also believe that there has been a HUGE software problem as well.

I've been using OP's "fix" for 3 days and so far it's working very well. I typically get locks in 10s or less, and accuracy 15-30 ft, inside. I nearly always disable wi-fi when I test GPS, but I've tried it both ways with this setup and it's working virtually the same either way.
At this point my only reservation is I've seen so many similar suggestions to tweak some setting that don't really pan out over time. This one may do the same, but so far so good.

I have done nothing but installed axura rom.ine locks in couple of seconds and works flawllesly. Even the accuracy is fantastic.

My gps went from bad to worst, 600 metter accuracy, maybe its the rom, ill try teamwhiskey. i been crying for a working gps lately.

I had applied both the hardware and software fixes while using many versions of Nero and my GPS would never get quick locks, usually it wouldn't lock at all.
Flashing Axura fixed my GPS too. Locks within seconds and has 7-9 meter accuracy.
Axura also fixed my fiance's GPS (with no hardware fix). She had the same issues with every other rom, slow/no locks. So I know it wasn't only my device.
I don't know what method Devs4Android used to fix the GPS, but it works perfectly. They need to sell the fix to Samsung so customers can get functioning GPS out of the box.

never had a problem with the gps locking on to sats and getting 20-40 foot accuracy. the problem is the drifting and staying locked once you start moving or just standing there. that is the problem i have. driving down the highway and bam your on the other side going the wrong way, or in the middle of the field a mile away. that is problem i have

Thankfully, Axura fixed that for me as well. Not only does it lock fast, but its accurate too.

After 2 days.
Last 2 days, I've tested my GPS in some different scenarios. In every one it has been quick and accurate enough.
I got 8 satellites in average, and the accuracy was of around 7-8 meters, something that has never happened before. I did the hardware fix, and it helped with the SNR values, but this is the definite best solution yet!
I'm still testing, but I've got a very good feeling about this method.

The only difference I see between this "fix" and other "fixes" is changing the SUPL server to supl.nokia.com. Since the original thread came from a Chinese forum, I'm guessing the SUPL server might work well in China. Not sure how effective this would be in the US or other countries.
That said, this isn't really a fix. All it does is change the SUPL server, which for most of us (using supl.google.com) works just fine. The Cold Start -> Delete GPS Data -> Lock -> Hot Start method will work just once because it clears bad cached GPS data if you've moved, but it's old news (dozens of other threads on this one) and it's not really a "fix."
The hardware fix is still one of the few real fixes out there.

So I take it you haven't tried this. I agree with what you say, however, I've been using OP's suggested settings for 4 days and see a significant improvement in lock times (only exception is I leave it set to Coldstart). I've been turning my phone off at night and after booting yesterday morning it locked in 14s first time, this morning in 7s. I know lock times can vary depending on where the sats happen to be at that moment, but this performance is much better than I was getting previously, which was in the 1-4 min range on first lock of the day. It's so simple to try there's no real reason not to see if it helps, unless you're already getting lock times like this. Only time will tell if it lasts, but so far so good.
(Running pure stock JI6, and I've also done the HW fix posted in the sticky, which definitely improved my SNRs.)

Another GPS FIX...

This worked for me. Please post comments here in this thread about how it worked for you.
I just wanted to sort of repost this information that I feel I stumbled upon. There was an article on the XDA home page about a GPS fix for the GT-I9003.

I am running

Kernal 2.6.32.9

My GPS was USELESS from day one. Sometimes half worked, other times you would have thought we were in a plane.
I tested my GPS just now before trying this and it found 12 Sats, only had signal on 3, and couldnt lock on any. I started with GPS Aid and all I did was:
Downloaded GPS Aids from the Marketplace.
Opened the App and went into GPS Aids
At the bottom clicked on "Download LTO"
I never changed any settings or any of what the OP said. I also never restarted my phone or anything. Just backed out of the app, opened up GPS Test and found 10 Sats, 5 Locked on with over 30 SNR, and 22ft Accuracy within about 2min. I have to wait until tomorrow to see it in action when I am driving, but things look promising.

thanks for sharing with us, will give it a try and will report back.

very impressed. clicking on thanks button

The only thing thats helping there is changing to supl.google.com port 7276
I've been saying it for months now that this is necessary, since the default supl server is actually offline. If you try hitting it from a browser you will even get one of those sites selling the domain.

Thank you!

I just tried mine last night while driving around at work(I cover a large area). Not only could I get a lock without a problem everywhere I went. But it actually showed me going ON THE ROAD let alone the right road. I could not get it to mess up. I turned SAT on and off a few diff times, restarted phone. The only thing that varied was the amount of time it took for the first lock. It still only took 5min at most and at one point I had 19ft accuracy.
so...YAY! My $600 "Smart Phone" can now do what a crackberry has been able to do for years and I found the fix on accident.
I tried everything in the "Vibrant Forum" and nothing worked. I had given up.I didnt think this was going to work because it was for a diff phone, but hey, I"m happy to know it helped people and appreciate all the "Thank You"

Funny thing is I never changed any of that. Mine is all still at default "www.spirent-lcs.com at port :7275"

If you try to go to any of those in a browser it says the same thing, damn some people ..... They wouldn't put a server in there as a stock server if it was offline you idiot. I'm sorry, I don't normally go at someone like this, but that was probably the dumbest statement I have heard in a very long time.

No, you are the one who is making a dumb statement. If you know what you are doing and try to hit supl.google.com on port 7276 it will show it is working as a supl server. Not so with the default one, there is simply nothing there but a placeholder, which means if you use it you are NOT accessing SUPL data for GPS assist. I've tested it on two vibrants side by side, the one on default would NOT access GPS data and thus took way longer to get a lock, until moved to a working SUPL server.
gg on your effort of turning XDA into the cess pit that its becoming.

My Telus Samsung Galaxy S Fascinate 3G+ (SGH-T959D) is supposedly to be a close bro to the T-mobile Vibrant.
====================== =============
GPS is a constant Not-Sure item on my phone.
Never know when it will/will not work. I was advised to up-plug/re-plug the battery when it failed.
After unpluging/repluging the battery, it has been working for the last 3 days as observed in the morning/noon running errands.
-- Using lbstestmode ; GPS status to monitor the status.
For supl/port, tried the values suggested, but found it would work just as well with:
* SUPL: Blank (typed in spaces; otherwise reverted to the factory value)
* Port: "7" (must have one value, otherwise reverted to the factory value)
-- Took about 5~10 minutes to see up to 10 satellites, and locking up (not all) satellites would seem requiring some sort of network connections (?)

UPDATE:
My GPS is still working. The only thing I notice is sometimes if I feel like its taking too long to lock on, I run GPS Aids and re download LTO. Then it locks instantly. But other than that it works great. I will def be donating/buying the Donate version of GPS Aids, it fixed my phone
