Strange error I haven't noticed until a few weeks ago.
I've tested in both Damage Control v1, v2.05, and Fresh 2.0d (current ROM i'm running)
With google maps/nav it always places me about 50 feet+ to one side of the street. It moves with the vehicle just fine, but always puts me on a side street, so if I'm traveling down a 2 lane highway it's constantly saying "turn right onto hwy xxx"
My GPS is always DEAD ON accurate though. I mean even inside my house if I'm at the front of the house it puts that dot within 5 feet, if I goto the back of the house (bedroom) it puts me RIGHT OVER that spot. The movement however is not so great. My phone while in the GPS mount has a clear view of the sky through the windshield.
Am I the only one experiencing this?
Google NAV is basically useless, because of the annoying constant re-routing.
I had this on Thursday when I was traveling for the holiday. I was using DC2.0r2 at the time however. I didn't have the same experience with my last install of DC2.05. I will repost after my trip today. Might be some time.

Same here.gps problem with 2.1?
Yes I have this problem. It's been mentioned in the main damageless thread and the bug thread so I think people are aware of it.
I was having the same issue with the dcr2 but it went away when I wiped and went over to freshes. Might be cuz It's based off the latest Sprint leak?
Works very well for me on dcv2. I think it's almost as good as co-pilot with the directions. It's so easy to start by going "navigate to 123 fake st". I usually had to restart my phone every time I wanted to use co-pilot otherwise it couldn't find a gps signal.
Also seeing this issue.
When I fired up navigator it started telling me to make the first turn (down the street) before I even got in my car -- so I had to use maps instead. Using maps, my marker was always a bit off. For example, it was showing me consistently North of the road (not on any road) when I was traveling West. Not sure exactly when this started, but I am currently running Fresh 2.0d, just for the record.
EDIT: Also, just FYI, this is with a good and proper GPS lock. It does follow my every move and turn, and is entirely responsive, but it seems as though my location is consistently mis-calibrated somehow, and always by the same amount/direction.
Anyone tried pushing one of the 1.5 gps.conf files to a 2.1 rom and seeing if it makes a difference?? I remember that was a fix in the early 2.1 roms from flipz that came out. Try it and see.
All seemed to be working OK today for me. This is like my third/fourth flash of a 2.1 ROM that seemed to have done it for me. No more flashing for a little while. Not that it is a fix at all, but I've had it both not work and work after switching out a few different ROMs.
I was going to make a thread on this. It was off for most of my trip. I muted the audio and just watched for my exit. After awhile it moved me on top of the road and it was ok, but it did it again a few other places.
It was a really odd bug. DC2.05
It worked for me in D1. But it's off in D2. GPS seems to be fairly accurate when just finding my location in maps. It's when I start to nav that it goes off.
It actually started doing that thing today where it can't find a GPS signal until it's restarted again, so I guess it's not unique to the ROM or nav software. My phone just seems to be bad with GPS if it's been a while without a fresh restart.
Has anyone tried using the Sprint Navigation on this or is it just Google's beta Navigation application? For me I never did actually try the Sprint nav, just stuck in the Google one. I knew where I was going the whole time, so instead of trying things I just shut it off.
Okay so now that I have my vibrant I tested it out (only a few times) but I did test it in different applications, websites, and maps and navigation. Yes in the gps and compass apps it doesn't pick up at all compared to my slide BUT in every other application, on google where it finds your location, on yelp, movie phone, maps, and navigation it finds my location each and every time. It doesn't get me lost, it doesn't show me going in a different direction, and it doesn't show me somewhere else.
What if the configurations or settings are different with samsung, what if the third party app is not completely accurate? Why else would every other program find my location if the app says I am not found by even 1 satellite? I think the"fix" is just a change of setting that helps the app not the gps or the phone.
Time will tell but for me it us working fine for now.

Well you can do gps tests within the os that say basically the same thing...
Ive used my gps with google navigate nermous times with no problem. in fact, it guided me on a 160mile trip just fine... What problems are people having with their gps?
Well, I've only had the phone for a day, so I'm still getting used to the quirks coming from a G1. GPS so far is the biggest disappointment. Android has been pushing location based stuff since the beginning, so the lack of a solid GPS is really screwing up some of my favorite apps. Locale for instance, it's worthless. It can't ever find me. The G1 always worked fine with it on Donut, Eclair, and Froyo.
Google Maps is the ONLY app I have that seems to even be able to get a rough idea where I am, and even then its circle is pretty big, about 4 city blocks. That's not GPS, that's network location, and it's fine for what it is, but not good enough when there aren't a lot of cell towers around. At home, it puts me out in the middle of a corn field. All the time I'm in maps, the GPS icon is up there blinking at me, telling me it can't lock. I've seen it work a couple times, for a short while. In GMaps and in GPS Test. But it takes a LONG time. The G1 could get a lock indoors in about 10 seconds. The Vibrant takes minutes, even with the A-GPS turned on in the test menus. That's insane. And it's not any better outside with a clear sky view. That might be acceptable, if it could hold the lock, but it doesn't.
Even stranger, in GPS Test, I get a single colored bar saying it's using that signal. There are 6 more with the same or higher signal strength being ignored. Very odd. Something is wrong with this GPS. It could very well be software, but Samsung needs to get on this and fast. If I can't find a way to get acceptable GPS performance within my 14 day period, I will likely return it. That will really suck, as otherwise I really like the device, but I need a decent GPS.

This has been my experience as well, and I found the same thing when trying a friend's phone. If only T-Mobile/Samsung would acknowledge that there is a problem and say they are working on it...
No problem here
But as I came from the G1 I use Google Maps exclusively. I haven't had a single problem with it. Inside my house I can get a fix on my location on the map, exactly where it should be. Are you guys using the TeleNav?

I have the same issue... I can only ever lock on to 1 sat. This is not right. My G1 would lock on to many birds.

I wonder if GPS Test is either wrong about that, or more likely, getting bad data from the OS or GPS driver. IIRC they are just parsing the NMEA data from the GPS driver, so "garbage in, garbage out". You don't get 20ft accuracy with 1 satellite being used.
I fooled with the settings in the "GPS fix 101" thread and got the thing working decently. Took a number of tries, and we'll see if it keeps working over time.
This really is something that TMO and Samsung should acknowledge and at least promise a fix for. Preferably with a close release date. And we shouldn't have to wait for Froyo either, get us a fix for JUST the GPS and a lot of people would be VERY happy. Well, that and the compass, that thing is even more worthless than the GPS before the fixes.
For the poster with Google Maps working, did you try with network locations disabled? Is the GPS icon in the status bar flashing or solid? If it's flashing, you DON'T have a GPS lock. Maps seems to be really good at using the network location stuff. I also enabled Skyhook in the GPS settings screen and Maps really seems to like that. Doesn't help with GPS performance though.

Wow.. that statement was idiotic. Maybe you aren't having the GPS issues that others are having but this thread is helping me debug and decide weather or not I'm keeping the Vibrant or returning it.
You guys are not alone. There is obviously something wrong with either the hardware, or the software. Either way, the buyer's remorse period is halfway through, and neither company has said so much as a peep.
I will definitely be returning my device by the time the remorse period expires. What a shame that would be, because I really love this screen. All it would take is for T-Mobile and Samsung to acknowledge the problem, and state that a fix is on the way.
Here's my post, detailing my contact and findings with the two companies.
It's been a few days now, and I've heard nothing back. Never a good sign.
EDIT. Got it working
Care to share?
So I have had my phone for almost two weeks and had only 1 ISSUE with the GPS not finding me, I was in a restaurant and could but find me for a couple of minutes, other than that working perfect. The other day I used the latitude app, I have never used this before, and now (I'm sure this is the propose of this app) it knows where I am at all times. So it goes without saying, this would help the people with GPS problems right?
As someone has stated before other phones seem to always have GPS working, this phone however turns GPS location on only when you use an app or program that uses your location.

Lattitude doesn't help
I have GPS issues with or without Lattitude. I have tried both and have yet to get to ANY destination successfully using GPS. I read today that Samsung is acknowledging the GPS problem and promising a fix. Can't wait.
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...

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.

MINE SUCKS
I have been using the (new gps fix) and here are its issues;
When on the freeway and driving around town at twenty five miles per hour my position is one block behind my location. the navagation tells me to turn when I am way past the street I was suppose to turn on.
The GPS still loses signal constantly
The accuracy on the Google map is way off in comparison to what the GPS program says the accuracy claims. It claims 30 to 40 feet and its 300 to 500 feet on the map. You better not be walking next to a cliff in the dark
and yeah I rebooted the phone, reinstalled Google Maps, and cleared the cach, and nothing has changed
Why did I wait for the update
I no longer trust Samsung.
The phone lag is getting worse every day and I have lost the ability to go to the market unless I reboot.
The battery life sucks as well, I cant make it through a day with out recharging.
Hey but the hardware is great if it works
Unfortunately I bought this phone for the supposed functionality and this includes the GPS.
Has anybody done any testing and what are your results or issues?
Did you miss the other threadS on this?
Delete GPS data
Wipe data, reinstall from fresh flash of JFD
Disable Use Wireless Networks.
Mine sucks too. Position in Maps jumps all over the place, it's usually at the far end of the error margin, and is relatively slow getting a fix (compared to a Nexus One)
Accuracy has never been consistent (usually above 10m)
The compass is really bad too.
There were improvements with JI6, faster lock, more satellites, fixed gmt and local time, smoother compass, but still far from reliable.

How do you delete GPS data?
mine is working awesome i did it last night and is working way better than before, in some places where i used to have 0 or 1 bar i now have 3 bars, the gps working without problems.
I have noticed bugginess still.
Twice now-- When turning on GPS, opening Maps, clicking the FIND MY LOCATION button.. it sits for a moment.. and then reboots my phone. brilliant, right?
Other than that, it is a bit more usable.. still not reliable like my G1 was.
When sitting still in MAPS, my blue arrow spins, jumps a millimeter, spins back... doesnt know which direction I am moving/facing.
Compass is still absolute trash.

I cannot complain about the GPS anymore. I flashed the ROM myself, formatted and repartitioned before...just to make sure. Quick GPS locks on plenty of satellites. It does seem that it works best in standalone mode on my phone.
My gps accuracy sucks (usually ~30m), but it does lock pretty quick. Subpar while driving, had me jumping around at stop lights and even lost the signal entirely for a few mins. In my opinion, not yet worthy of the title "gps." i'm on stock ji6.
Sent from my SGH-T959 using XDA App
My GPS seems pretty good, although it was good before the update since I used the leaked GPS fix.
The only thing I've noticed since I odin'd the official JI6 is that my battery seems to drain a bit faster than before, but I might be using it a little more than before as well, so it's hard to tell.
My only complaint is that when I turn on the navigation app it takes several minutes before the gps locks. Once that happens it seems fine.
The same is true of my Garmin standalone gps, so maybe I'm expecting too much.
Hey in case anyone is interested, GPS is working great on the Bionix 1.8 ROMS. I get a constant viewed 11 and locked 9-10 within 3-4 seconds and the tracking is very accurate.

I'm using Bionix 1.8 and it will take minutes sometimes to lock and then for no apparent reason the lock will drop. Mytracks still has me driving through buildings as well. It's better but not fixed (at least on my vibrant).
mine works flawlessly. All I've done is root with Ryans OCLF and never removed any bloatware. I do have the recent JI6 update.
Working great after the update..

I totally agree with you on this, I had stock ROM, flashed to Bionix 1.8, after the initial waiting period to grab a bird, I have since seen consistent locks (within SECONDS) using this ROM with JI2 baseband (to avoid data improvement/battery issues). It is now working in my house where it wasn't before. In particular with Wireless Networks turned off, that little satellite icon locks right quick.
Can endorse the Bionix ROMs highly enough, this thing is truly butter as advertised.
Also, this is with factory GPS settings (not supl.google.com).
Salud, happy vibrant-ing!

I upgraded yesterday through mini Keis, and locked on to 9 of 11 satellites, indoors. I tested this morning while driving to work, it was accurate, and navigation App works like a charm. Loving the layers and satellite view!
Before, I could rarely even get a GPS lock.
