Hi Guys,
I've been hearing about lots of problems with the GPS not picking up low SNR satellites and the GPS being wildly inaccurate on the samsung vibrant and also the euro variants of the galaxy s.
Does the captivate have the same issue?
Its true. I bought it on sunday an notice that issue. Hope there will be a update(Bug fix) soon.
Compare to my G1, the Captivate take about the same time to lock and GPStest says the SNR is better. I'm happy with it.

Define Wildly inaccurate. On my Captivate it is dead on (within 9 feet)
I am having major problems with GPS. I am getting a lock but only within 50-75 feet. It isn't good at all. The GPS is slow to update and throws me everywhere.
I amthinking of returning the phone if Samsung doesn't make an announcement about s fix for this.
dial this from your phone:
*#*#1472365#*#*
Change startup from hot to cold.....worked for me. GPS locks much much faster
What are the settings on your phone Citznfish? My phone is off by anywhere from 100-500ft. Thanks!
Ok, I tried it again... In the house I'm about 500 ft off from where I really am and placed in a golf fairway. Outside I am FURTHER off: I'd estimate at least 5 blocks and placed in the middle of a different golf fairway. For comparision sake, my wife's iPhone 3Gs has her within 10-20' while inside the house. To me, this is unacceptable and a great cause for concern. What can I do???

I'm having the same problem here. My iPhone 3GS GPS responded way quicker then this phone does. I have a Weather Channel widget up, and it doesn't find the location to display the weather for a good minute and a half after. Same goes for using Google Maps to find my location. Lot of times it says, "Your location is unavailable." I even tried switching the startup from hot to cold, and that didn't have much effect either.
When I was driving today, the GPS locator had a bad lag in it, I would be down two blocks before it would catch up, and I live in a 3G area, and not a giant city like NY or something.
I wonder if it's because it's so bloated with Samsung UI on it, or if it's just the a bug. Either way, if I'm still having issues with it, I'll see if AT&T will exchange it out for a different one. Otherwise back to the 3GS, which I really don't want to do since I'm loving Android right now.
What does hot start and cold start do?

Hot Start - The GPS receiver remembers its last calculated position and which satellites were in view, the almanac used, and the UTC Time. It then performs a reset and attempts to acquire satellites and calculate a new position based upon the previous information.
Cold Start - The GPS receiver dumps all information and resets. It then attempts to locate satellites and then calculate a GPS lock. This takes the longest because there is no known information. The GPS receiver has to attempt to lock a satellite signal from all of the satellites, basically like polling, which takes a lot longer than knowing which satellites to look for.
Danm a cold start sounds like it would be slower. I tried it and I still can't get a lock within a reasonable range.

I've been reading online that the Galaxy S got a firmware update that greatly improved/fixed the GPS problems we are experiencing. I can only assume that we will have to wait as well for this firmware to completely fix the gps issue.
Try the fix/workaround in the Vibrant forum.

I went from seeing 1 satellite and none locked to 7-10 seen and 5-7 locked.

Where did you read this? I've been looking for something like this, preferably from Samsung.
i havent had too many problems with GPS here
Google maps usually locks me in a few seconds
Third party applications can take much longer, however
The problem might be the way the third party apps utilize the GPS

Actually that isn't a fix at all. It makes locking onto satellites much faster, but nothing to address the sensitivity issues, and there is definitely an issue. I 'found' 9 satellites, but could only lock onto two of them, for a few seconds at a time, then back to zero, out in the open.
Hopefully a software fix is on the way.

This fix did help me so now i get a quick lock...as ling as i dint start moving around. It stays close enough to exact to use for driving around but not more accurate than that. The problem isn't really getting a lock so much as keeping it.

Well, I change my mind. While what I said still stands, I've since found that the GPS and the Compass don't track very well. I tried find a geocache using the same GeOrg software I use on my G1. The location seemed to be stuck as I was walking. From my experience with the Tilt, I'd say the GPS is running in "Static Navigation"
The clock is ticking, GPS has to be fixed in 28 days, or the phone gets returned.

I was having problems w/ GPS on my phone as well. Would be way off in Google Maps, Navigator took forever to lock, and geo-tagging photos was also way off. I did something similar - dialed the code to get to the GPS settings. However, all I did was turn Skyhook to ON and switched configuration from manual to auto. I don't seem to have any problems between yesterday and today. It locks incredibly quick and is very very accurate.
Some of you should try this method and see if it helps with anything. Good luck.
Is the GPS working now that Froyo is on your Captivate? I have a brand new one on the way to me via FedEx right now so I can't flash it till I get it and wonder if anyone can tell me if GPS is fixed since Froyo is now available to the phone.
It's a lot better. But its not perfect. I'm still in the 3 day "GPS is guaranteed to work better" window so time will tell
Mine doesn't work at all. With all kinds of combinations of GPS setting tweaks.
Thanks. I hope it works better. The phone is still nice so I guess I'll be happy with it even if it's not perfect.
I hope Samsung has another fix for it since it's not working for everybody
I'm doing better but it still sucks.
GPS, using GPS Satellites only with default GPS settings will not lock onto ANYTHING AT ALL for me.
With cell towers, it's 1400m accurate.
Not sure what changed between 2.2 and 2.1 but with 2.1 GPS worked great for me.
Very strange that GPS functionality is different from phone to phone, software to software.....
I do hope they release an actual total GPS fix someday.
Edit: I still like the Galaxy S phones. I know Samsung is still very high tech. It may take them awhile to catch up with what people really want with an Android phone but other than that they have have put together some very nice phones with the Galaxy S line.
mine will pull me down to 10-20 meters. and according to lbstest, it shows it as 15m accurate, full stand alone, lock in between 15s-90s.
Driving around, it was the worst it has ever been. I then used GPS Status and left it up on my dash. I generally could see 2 or 3 satellites. Once, it got up to 4. This is during a sunny day with full view of the sky.
People still seem to think they have something great if it locks in their house, but the real test is driving around and seeing if you can KEEP that lock.
I noticed using ANY of the "GPS fixes" destroyed my GPS performance. I need it set to Standalone, Cold Start, AUTO SUPL config (no supl.google.com) and none of the Jupiter XML "fixes". Stock froyo GPS seems to work OK for me -- I get locks in a reasonable amount of time, although accuracy still isn't great. I still have yet to test Google Navigation / My Tracks, however.
A lot better for me......Many sats in view. Quick locks. Google maps tracked my car pretty quickly on 2.1. I would say this is as good as can be expected from a cell phone GPS device. I have Gamins for the cars so I really won't use this as such. but on my motorcycle it works very well.
It will not be perfect and I accept that. It is A lot better though than 2.1 IMO.
It is marginally better than JH7. Still broken for sure.
Stationary it's fine and gets a pretty fast lock.
Car navigation is poor. I was getting better results in Cognition 2.1.5. Positioning is jumping around, putting me a block away about 25% of the time, getting various sizes of the blue "circle of trust" about 50% of the time. It freezes occaisonally but maybe less than in some of my previously used ROMs. I've tried all the usual setting adjustments and they haven't helped.
The GPS nav capability on the Captivate in prior ROMs has been good enough for me to declare it satisfactory. I'd say this version isn't- yet. I'm confident we'll get it back to at least what it was, but it will take some more tweaking.
Just wondering if anyone is able to get reliable GPS locks in airplane mode. I am beginning to question whether I should switch to Xperia X10. I use GPS quite a bit and don't see why I need to get another GPS when the Cappy should have a working one.
I do love everything else about the Cappy. Hate to go to an outdated system but having everything working as described is kind of nice.
In my testing and experience it is much better, but still not as it ideally should be. I get nice, fast locks in Maps, but GPS test apps are still confused. Perhaps the whole benchmark vs practice concept, but this case seems to a little outside of that realm.
I was able to get GPS lock to around 10 sats only after deactivating the "Use wireless network" option.
However, I had no nav app so i cant say how it tracks.. I am back to 2.1 now, waiting until 2.2 wont be so laggy

This is interesting, as I keep thinking of switching to a Galaxy S because SE's so slow about updating to 2.1 (Maybe November?) and 2.2 which is a requirement for the latest Gmail and GDocs may not come until Spring 2011 if ever.
However, GPS is extraordinary on the X10. I live on the side of a hill and I can get a lock in 3 seconds,starting with 7/7 and then 8/8 sats by 30 seconds (every option turned on). Lattitude, Navigation, Maps, etc all work wonderfully.
WiFi and GPS are the two most 'additional' features for me on a phone. I have a bit of an issue with SE's Wifi as it's only working when the phone's awake and if the screen blanks, it switches to 3G. Leaves you tethered to a plug so you can set the screen to stay on when plugged in.

I just realized that I use GPS more than I expected. I think 2.1 without multitouch is ok for me. I am still having daily random shutdowns though mine is limited to unplugging from AC only. I am still waiting for something to happen to Cappy cause I still like it.
I have an RMA phone that I updated OTA to JH7 and yesterday i had to drive out of state and about 20 minutes before I left I updated to Froyo 2.2 stock and my GPS worked perfectly the whole way there and back. Granted it was only about two hours of total drive time ( I am really close to the state border), but it never showed me off the path it set for me and when I passed the spot I was suppsed to go to, it showed me drive past it. So I have as stock a setup as possible and my GPS worked perfectly for me. I cant tell you how many sattelites I have or how many seconds it took to lock etc., but real world road test was great. i will use it tonight on my way to and from work and maybe repost now that I have had it loaded for a day.
Im seeing GPS complaints starting to crop up. My two day old Infuse does not get a GPS lock at all. Figured maybe we can start a poll and see what kind of leaning we get towards GPS performance on this device and show it to Samsung should it look like its a major problem.
i've had no issues at all with my GPS...
This is my third infuse. My first one had battery issues. Second woulndnt find a GPS in the vast sky. But this one is near perfection.

Infuse GPS - Location Difs?
I'm having a lot of trouble getting the Infuse to find the GPS. I keep getting messages that it's searching for the GPS. However, when it does find it, it works wonderfully. I live in Southern CA and having a difficult time here. It's not locating me correctly and is unable to provide navigation more than half the time. However, in Northern CA last week, it was working well. Do you think that the location makes a difference - or is it something with the individual phone?
Can't be I'm in sandy eggo. My second infuse didnt find any signal while my friend two feet away with an infuse had it working in two seconds.
Sent from my SAMSUNG-SGH-I997 using XDA App
dont try these side by side comparisons unless you clear nmea data on both devices before hand. it can be difficult for the gps chip to download the data from the satalites directly. another device may have downloded data that is still current at any time. side by side in only side by side if both devices have a cold start and are working in the same mode.
if you have trouble with initial locks go to the phone dialer and type *#*#3214789650#*#* it should take you to lbs test mode. it can also be launched with launcher pro activities. in lbs test mode delete gps data then go to supl/cp settings. write down the supl server and port. try a different supl server like supl.google.com with secure socket set to off and the port set to 7275. or you can set it to auto config. if none of that helps try setting the gps to msbased in application settings. msbased will use cell towers to download nmea data and give the gps chip a head start.
some phones (like my captivate) dont like ms based mode for tracking but my infuse works great with msbased and supl server set to auto config. if none of that helps trade in the phone, you have a defective unit.
there were situations where a factory reset helped on the captivate but mine suffered from a specific bug where the glgps daemon would crash with certain settings, wiping gps data did not solve the problem but a factory reset did. i dont think the infuse suffers from this bug but it couldnt hurt to try a factory reset.
Another GPS post. Fine, 7-8 gps locks no problem between 3 states. I guess if you can't beat them join them.

Agree. And most people don't understand that the first seek time can take longer. So until the device learns your area it'll take longer to lock the first time in a certain area. I travel all over the world, and everywhere I go that I haven't been before a phone takes a bit longer to lock.
I think people forget about the days of the original GPS units that would take 5-7 minutes to lock on first use in a locale. Now if it takes 30 seconds they scream bloody murder.
EDIT: Why is it whenever there are polls like this people who click a negative, like something doesn't work or doesn't always work they almost never elaborate in comments? If I found this thread and had GPS issues, I'd vote, then elaborate on the problem to see if someone can help. My guess is you're spot on with user error.
My GPS was mediocre from day one. Today, did a factory reset, used tibu to restore all apps except maps, fresh install of maps from market. Had a lock in seconds. Will see what happens in the next week or two.
im not gonna say there arent bad units. and the settings could certainly be better, but i see these threads in every forum about every phone, and my friends complain about there phones. all i can say is that it get blown out of proportion.
i had a captivate and despite limited accuracy and agps that would hinder tracking it never steered me wrong after a few slight tweaks. every time i tried to follow someone elses mods it got worse. da_g's fix fixed the glgps deamon crashing while i was driving, though it only crashed if i used agps settings in the first place, so just changing the supl server and using the most recent modem.bin and setting secgps.conf to standalone to match lbs test mode was all it took to get a great tracking gps even on google maps.and it locked pretty good under cover.
the infuse is way more accurate getting <10meter locks quickly and showing the accuracy to the .01th of a meter rather than using multiples of 5 meters like the sgs. i can typically get 6 meter locks on the infuse sometimes less, with consistant altitude and 11 sats visable. if it gives you trouble i would blame google maps, it is clearly not a hardware issue. changing the lbs settings or secgps.conf may make it better but it is better to have a gps program that doesnt use data so before you complain replace maps with an application that has it's maps stored internally.
10 days in... Not one GPS issue. I just returned home from a 4 day business trip to Washington DC. During that trip, I used the Infuse often and enjoyed comparing it to the Garmin that came with the vehicle. The Infuse won hands down. The one huge triumph was the Google Navigation's ability to properly recognize traffic delays and re-route. I used it and it actually worked like a charm! The Garmin traffic portion didn't work at all. It basically didn't see the traffic that the Google Nav picked right up.

Working fine here, just hoping I'm not jinxing myself by saying so
I was using Google navigation yesterday on the Infuse while in Kissimmee and it moved a long with the car 95% of the time, it was great! Took me exactly where I needed to go without an issue. The Captivate couldn't do this at all!!
My GPS still doesn't work, indoors, outdoors, in my car etc. Guess ill need a replacement. Thanks for the input people. Thats what these forums are for. To either uncover or put to rest potential issues, amongst many other uses.. Sorry if i "offended" any internet elitists.. Again i appreciate the useful input though.
As you may know by now I've been having problems with GPS on my Nexus S (i9023, bought factory unlocked from Amazon Germany, carrier code EUR, running rooted stock 2.3.4 AKA GRJ22). A quick search of the Nexus S forums will tell you that I'm not the only one who complains about GPS issues - I always assumed that the GPS was just sub-par on the model and I'd have to live with it.
Only now a few helpful souls over in the accessories section said it was probably defective and I should exchange it. (I've already exchanged it once for this and the new unit I got performed exactly the same.) So I'm just going to tell you the current situation and I'm hoping you'll tell me if that's within the normal tolerances for the model: [All tests done outside in suburbia]
"Network location" (geolocation, wifi / cell triangulation) is fine since 2.3.4 [just to get that out of the way]
Time to First Fix (TtFF) is decent now, usually 15-30 s cold and < 15 s hot. I've seen much better (yes, on a phone), but that doesn't bother me.
Accuracy however, is still bad. GPS Status shows 20-10 m mostly, but it fluctuates wildly going from 5 to 30 in a heartbeat even when it's just stationary. Other phones don't show this behavior. This translates into real-world problems in Maps (checked via sat view): The blue circle goes from large to enormous and back and while my true position is somewhere within the circle most of the time, the center dot is way off. Most other implementations manage to guess the location correctly even when the accuracy is bad (as tested side-by-side).
Stability is my biggest concern. The lock'll be fine for a few minutes, especially if the phone was just rebooted, but then the GPS will lose it every few (say 5-10) seconds and take time to reacquire it. Additionally, it doesn't pick up movement very well. I did a few tests watching my position in Maps while on the tram (in a window seat) and basically it would register an (approximately correct) location every now and then but then just hang there for a while. Usually it wouldn't register that the tram had left a stop before it had arrived at the next one or even just left it again. All other phones trace the tracks almost perfectly and in real time. There goes any kind of usable navigation and - in concert with the compass issues - all augmented reality apps.
Again, this isn't meant as a complaint or even a request for a fix (though if you have one I'll gladly take it) - I'd only like to gauge if my particular phone's have been bad or if "that just how it is".
Thanks for listening.

I even think my GPS is the worst of all the Nexus S.
Mine was bought from Ebay-UK and since it was on a repairing-tour to samsung germany i know its from CPW. Its a I9020 not I9023. BTW there was nothing repaired because they said "The discribed issue cannot be found" or something like that..
what do you mean with compass does not work for anyone?? does it really not work on any nexus? thats interesting, isn't it a little bit illegal to sell a device and say it has compass and than compass does not work at all?

the GPS on my NS behaves similar (but better) to what you describe in the first post but overall it seems to have better accuracy and stability.
Have you tried recording a track while in a car? The results should be better. At least with mine it's mostly accurate and rarely looses signal (unless you go under a bridge/tunnel)

Hello,
I have the same phone, NS4G from Sprint, and the same symptoms. The GPS worked fine for a week or so, and now I'm lucky to get it to work at all. Sometimes I can get a lock after 5+ minutes (while not moving), but other times it never occurs.
I just tried resetting the GPS as is described in the post above. It says "it will reboot automatically" - does that mean the phone or the radio?
In any case I just pulled my device battery after GPS reset - I'll post back with results in a few minutes. In the meantime can you explain what you did after following the reset with dialpad/MSL?
Also attempted return...had to send in for repair
I also got a bad GPS Nexus S i9020 from Amazon.com USA site. The GPS would not lock without a wifi signal. I eventually caved in trying to get it working with rom flashes, drove me nutz, but tried to return for cash and missed the date. Had to send in to Samsung then and get the repair. I have been somewhat satisfied, having gone from no GPS to finally getting it to lock, but its a poor excuse for a gps chipset. The SiRFSTAR from my old WinMo days kicks this gps in the arse.
I also get the bouncing sensitivity and wandering location circle, but accuracy hovers around 5-10m now, but the location is never fixed solid, its wobbly, even outside with clear skies above. The compass is another huge weak spot. Samsung dropped the ball on this device, I wish I could return mine and grab an HTC unit. Google should learn from this and drop them for the Nexus Prime. I think this is unacceptable as location services are whats hot now and this device fails as a flagship product.
I like the gps on my sgs2 more (it has a sirfstar IV) but, i have to say, it's not that much better.
What i gained in stability i lost in TTL. Sometimes you need one more than the other.
The SGS2 has taken me up to 10 minutes to get a lock and if conditions aren't good (cloudy sky, tall buildings) it can easily take 5 minutes. Sometimes you just want to get some signal to get you going.
I did a trip of more than 2000 miles with my Nexus S, using the GPS most of the time, and it worked ok enough for navigation for most of the time. The only times it failed me were, as i mentioned earlier, in old parts of cities with narrow streets.
You are right when you mention HTC, because usually their devices have better working GPS.
Overall i wouldn't say it's a bad device, you have to keep in mind this is not a dedicated GPS device, it's a smartphone that does a lot of things, some better than others, it's still a good developer phone, which i think was the main goal of the Nexus.
After upgrading to the SGS2, the main differences i noticed were not the GPS but the speed and extra memory! The Nexus S is not slow and has average memory (512mb but with only around 380 free) but if you have a lot of apps running (and it's easy for this to happen) it will get sluggish and begin to close the launcher when you start a heavier app. I found this had a lot more impact on usability than the GPS weakness.
I was reading that the samsung galaxy sII is also having the standard GPS problem that samsung is famous for. If you dont now what Im talking about, go use an HTC phone and watch the phone instantly lock on your position in <1 second with 3ft accuracy while you are indoors..
my Charge has been "Acceptable" when using GPS, but lately it has taken upwords of 20 min and a few reboots to get a lock on my location. Using GPS test, and Faster Fix do not work. GPS test just sits there showing me 9 satellites in view but locking on none.
apparently there is an update for the SGSII that actually fixes this problem.

So to the devs that are in the know, where is the GPS modem firmware located? It is not in the base band modem sets as I was thinking. Is there a way we can use the sgsII update on our phones?
I love my charge, and Gummy2.0 is amazing... but I need a working GPS, the damn thing cost me a job interview yesterday when it refused to lock and get me to the place on time.

I agree that the charge may not lock quite as fast as some of the HTC phones I have owned, but my GPS performance is certainly acceptable.
I am running gummy 1.9.1 and just returned from a one week trip all over New England and my GPS worked just fine the whole way. I used it MANY times to find locations I had no idea how to get to and it worked perfectly every time.
I used GPS Test Plus & did the XDA tweaks & it really does work just fine.

My gps was working acceptable for a while. In fact since updating to gummy 2.0. I have no idea if roms change the gps firmware. I expect not. But this is why I am looking for a way to verify the gps firmware. Then the problem can be tracked down easier.
I know I am not the only one with gps problems. And I am a very heavy gps user. Something is definatly different now.. my gps is non functional in its current state.
Make sure you guys turn off google location and verizon location services and only use stand alone gps and test with gpstest app before saying your gps works fine.
My problem is basicly this.. I turn on google maps and it will simply fail to get a location. I don't get the arrow with the large circle with an accuracy of 1600 feet.. it just says 'unable to determine location'. And then quits.
So back to my OP. Where do we find the version number of the gps firmware?

Maybe I'm just lucky, but I just fired up GPS Test Plus & in under 30 seconds it said nine satellites visible with eight in use. I then fired up Google Maps & the arrow was right on top of the building I work in.

By the way, I am a LONG TIME GPS/NAV user & understand how it works.
My first Garmin unit had a B&W screen with no background map.....
