Has anyone ever stopped to think that maybe the third party GPS apps are wrong?

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.

This thread is idiotic.

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?

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...

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.

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.

[GUIDE][FIX] GPS finding satellites, but not connecting

tl;dr version:
1) Switch data on. (not wifi, data. Has to be data.)
2) ? ? ?
3) PROFIT.
looong version:
I kept wondering why GPS would find many satellites, but would often not lock onto them, or would take a very very long time to lock (around 10 mins or so). Then I noticed that it works fine when data is switched on, and locks within a few seconds.
You should get a lock as soon as you're "fully connected to Google", and "go green" for people who have that enabled.
This is the a part in agps at work Assisted GPS. Click to check the wikipedia article on it.
Accuracy is still a problem, and testing with a friend's DHD, I was getting around 10-6m accuracy, and he generally got 2-4m.
And Samsung's GPS software sucks too. glgps daemon's internal smoothing algorithms are still there, and it's annoying.

If you go to the Location Settings, and Untick "Use wireless networks" and Untick "Use sensor aiding"
You will get a GPS lock even without DATA. BUT, it will take longer.

Not on my Sgs... with those unchecked and cold start I still get a lock within 10 secs. So something funky in Sgs ii his stuff.

So does the SGS2 have similar GPS issues to the original? I'm currently on the Samsung Captivate and have a preorder in for the SGS2. One of the big reasons I'm looking to spend 800 bucks to upgrade is to be done with GPS issues on my phone. If this won't be the case maybe I need to give up on Samsung and wait for HTC to release a dual core beast on AT&T bands...

I have no experience with the earlier Galaxy's but I can compare it to a G2 and G2X. There are three GPS settings: Use wireless networks (cell and Wi-Fi), use GPS satellites, and use sensor aiding. With "use wireless networks" checked and Wi-Fi off it just locked and loaded for me in Google maps in less than a minute from a poor location. With only "GPS satellites" checked it took closer to 2 minutes. It was accurate down to my street address both times. In order of speed from "activation" to "usable" I'd rank the phones in this order: G2, G2X, SGS2. While a bit slower to lock than the others it's fine (accuracy, holding lock) for me. Someone from the EU uses Tracks to measure his walks and was complaining about the street-level accuracy. You might want to check out that thread.

I personally never ever would use the WiFi- and Sensor functions as GPS replacement.
Why?
1) It is responsible for the collection of the location data and sending it to Google.
2) It costs battery power.
3) Why using when the GPS fixes fast enough? What's the problem with waiting for 10 seconds for a fix?
The fix can be made quicker by DL'ing the "GPS Status & Toolbox" app and using it for DL'ing the actual valid GPS sat vectors. That helps the GPS to fix quicker.
Cheers

Mine is very slow to lock, despite having plenty of sats visible with good strength.
This is compared to 4 different ZTE Blades that showed me how quick locking can be, even indoors.
There is a tool on the market called GPS Aids which was developed for the Galaxy and I'm keen to discover whether this can improve the SGS2.
However, it requires rooting and I'm reluctant to do so as I may decide to replace my phone if it can't be sorted.
Is anyone who is rooted willing to carry out some tests using that or other tools to see whether performance can be improved? I'd really appreciate it.

I've used GPS a few times, and it works fine. Accuracy is a bit weak sometimes (compared to other phones) but it's fine for navigation, and even using mytracks or similar. (although when it goes off on mytracks it'll take a while to get back due to Samsung's inane smoothing)

Not sure why it's like this, but you have to have data enabled for it to get a quick lock on SGS II, otherwise it'll take a few mins.
I'll give GPS AIDS a test later on. Maybe.

My gps has been spot on from day one-locks in seconds and google maps always puts me in right room of house or parking space etc. The blue accuacy circle is bigger on sgs2 then sgs1 but the reall accuacy is tons better.

Hi everybody.. i have downloaded an app called GPS aids v 2.0 and this has helped me in getting a lock in under 15 secs after which i fire up Sygic and it hardly takes 10 secs to lock my position.

Interesting GPS find

So my GPS works pretty well when I am outside, but when I am inside it can be pretty bad, I live in the first floor of a 3 story condo complex and its pretty rare that I get a lock inside, without using GPS Status or any AGPS download tool, which I personally find is not needed when it comes to getting your GPS working.
Well I installed the MapQuest app, please don't flame me for not using google, but that app has been getting pretty fast GPS locks now.
https://market.android.com/details?id=com.mapquest.android.ace&feature=search_result
So just from my observances it seems like a mismatch in coding with the GPS and Google maps, and Mapquest can atleast turn on and good a good/decent lock with it.

Ever been to the Smithsonian Museum or Library of Congress?
For the OP, the app has nothing to do with the fix time, the GPS is run via Android API, not direct hardware access. You just happened to get lucky or had recently run the GPS and the satellite positioning cache was still recent.

I always thought it was just a bug in Google Maps. Whenever I have trouble getting a fix, I switch to something else, like Bing Maps, and it locks instantly.

I would agree with you, but I rebooted a bunch and tested it, and it had been about 3 days since I used the GPS, I used Mapquest and it it locked pretty quick.
And this morning, which normally after not using not using it for about 8+ hours it doesn't work. It wasn't locking this morning, I opened map quest and it started working again.

Hate to admit this, but this works for me. I've had issues with locks as well as accuracy (always zeroes in to a not-so-nearby spot). I've done the ntp pool edits (which helped a tad). But Mapquest somehow "unblocks" and gets a more accurate location. Then when you open Google Maps it somehow works okay now that Mapquest paved the way. On the other hand, Mapquest forces your WiFi on without asking.

Sounds like maybe mapquest us downloading agps data everytime. Seems that google maps expects a functional gps and waits for your phone to handle the data retrieval and fixing. Shame.

If there are any wifi networks visible (doesn't matter if you connect to them or not), Google's Location Services might be the one that's actually finding your location, not the GPS.

Is this how agps works for sure? aGPS just appeared one day years ago and I've never really learned how it worked. So it downloads a sat position map based on tower connection or something similar?

Remember, the Galaxy S phones were built with SkyHook's aGPS system in mind. Google forced Samsung to rip it out really late in the day after the Moto/SkyHook deal was discussed in the press.

I turn my wifi on when turning on the gps and now I get lock in google maps every time within seconds.

Just a follow-up observation, probably obvious to most of you... but doh! not to me.
GPS and aGPS performance has many variables, location and radio being two significant ones. I've recently downloaded GPS Status from Market that some of you recommended (thanks again!) to help figure out what are GPS vs. aGPS locks on both Google Maps and Mapquest, as well as assist with diagnosis.
http://www.appbrain.com/app/gps-status-toolbox/com.eclipsim.gpsstatus2
Using a sample of 1, it turns out that not only am I located in a poor signal area (1x if lucky), but my GPS availablity here is terrible, too. (This also supports the theory that I will always have relatively terrible battery life, as the phone is always struggling for signal.)
ED03
My earlier post shows my enthusiasm for Mapquest, except that it uses aGPS and turns the Wifi on without asking, and also runs hot. I use Mapquest to get things moving, then use Google Maps as I prefer its interface and functionality.
ED03 --> EA28
Recently switched to EA28 (still under Froyo EF 3.3.2) in an attempt to minimize missing calls as well as get better data performance. Got terrible GPS and aGPS. Even Mapquest has started getting "lost". Call signal / performance is marginally better than ED03, but at the expense of GPS accuracy.
However, when I travel to an excellent 3G coverage area, somehow the tables are turned and Google Maps pops us quicker and accurately, while Mapquest is still busy trying to catch up and draw the map.
ED03 --> ED04
As the effort to switch modems around have become trivial, I decided to get the ED04 modem in case there are any improvements to either call performance or GPS. So far GPS/aGPS is still terrible in my normally terrible coverage area. Too soon to tell if call performance improved, or if missed calls problem is fixed.

ED04 was such a bad modem with missed calls galore, I quickly ODIN'ed the EC09 modem and was pleasantly surprised with better performance -- calls and GPS/aGPS.
A road trip to the "countryside" then revealed that the countryside had better VZW signal and GPS than my normal location! 3G and GPS accuracy and quick locks... so this is how the phone should work!
Finally got back to the land of poor VZW reception, and had to focus on minimizing missed calls. Between the EC09 and EA28 modems -- EA28 had less missed calls so that's where I ended up. But both have excellent GPS performance in both great and marginal reception areas, specially compared to the EDxx series. ED04 was quite a flop for me.

Anybody here know if it is possible to get a replacement for their phone because of the Fascinate GPS problems? By replacement, I mean a different phone and not a refurb with the same problem.
I've been able to live with the phone not locking and being almost right most of the time, but this last week I really needed the GPS to lock and work and it wouldn't. Driving around with broken AC in 105 degree weather was the last straw.

Does mapquest initially turn on Wifi? I tried this by getting mapquest from the market and tried to see if it could find my location. I accidentally clicked the home button and when I saw my power control widget, I saw wifi on and then it suddenly turned off. (I have wifi off almost always).

GPS not working on 2.3 ROMs

hi.
It seems now that every 2.3 based ROM supports GPS, and people say they get a very fast lock.
But I was never able to get a lock with any ROM, I have tried several versions of MIUI and several versions of CM7.
The only ROMs I am able to use GPS in, are Froyo based.
Even there, it takes around 5 minuted to get a lock.
I did the hardware fix half a year ago, it helped very much because I was using Froyo then (it took only 5 minutes vs 15 minutes to lock) but now it doesn't lock at all.
Any solution?
Thanks.

i applied that fix and noticed no improvement, unfortunately. i had great hopes for it from reading the comments others had left about success using it.
the gps on my vibrant (running CM7) is quite odd.. it seems to 'know' where i am, but won't ever get off of the 'searching for gps' message, and of course, won't switch gears to the point where it actually tells me where to go. but if i want to look at my location on my phone and follow the 'map' it displays, or read the directions, it sort of works, in a hinky sort of way.

Try a program called GPS Aids from the market - Ive had mixed results with it.

I think that you are using the AGPS function, which uses the WiFi and mobile network to determine your location. It is much less accurate than GPS, which doesn't work.
About the GPS fix and GPS AIDS, I will try later and post the results, thanks!

that makes sense.. its just getting rough position with the mobile network.. (i usually have wifi antennae off)
last night i downloaded a gps test tool from the market... ZERO satellites... and mine worked perfectly when i was running Axura. i'll probably be going back there very soon.
