How bad the GPS problem is?

Lets see if I understand this correctly....
on the samsung galaxy s GPS system, there are 2 options:
1)Use wireless networks: Set the device to use the
wireless networking to indicate your location
2)Use GPS satellites : Enable the GPS receiver to indicate your location
For now, we know that using the option 2 gives us crappy results (loosing signals, cannot lock sattelites, jumping around etc)
Now, for option 1: choosing option 1 means that launching the maps application should indicate where your location is currently by using some kind of triangulation method based on the availability of GSM signal, so it should even work when you are indoor or whenever there is a GSM signal......
But apparently on this phone, it only shows your initial location, then after that even if you have moved 1 km from your initial location, the location indicator arrow is stuck at your initial location, meaning that it doesnt track you and your movement, which means both options simply dont work on this phone....
On my wife's iphone, the GPS functionality works wonderfully even when i am inside a building and it keeps updating your location as you move continuosly.
It just shows you how careless and hasty samsung is in launching this product that even the simplest form of GPS functionality, one that is based on GSM triangulation method, also doesnt work..... and they still went ahead with the launch.....

Absolutely no problems with GSM or GPS positioning now that I'm using I9000XWJG5. Locks on satellites within 22 seconds from switch on. Thats at 30m precision. After 10 seconds more gets to 5m precision.
This is from inside my building. (Using GPS Status to check)

Same here. Your wife's phone probably also uses the mobile network to keep location inside buildings, or wireless networks. Try enabling skyhook, that is all i did.

used skyhook, and assited mode, accuracy set to 50, changed supl/cp settings, but compared to my g1 or hd2 or e61 or 10 year old bt/gps mouse the gps quality is just rubbish. (XXJF3)

no problem even without skyhook, but using skyhook gets locking much faster
i'm comparing it to my old HTC Athena, which takes sometimes over 5min to lock to 1 satellite in the great white open sky.... sigh...
sometimes it wont even lock if the weather is poor, takes like 30min or more to lock, under those conditions.
simply insane.
so SGS i9000 is like a dream to use.

g1 / hd2 / e61 only take seconds to get a full lock with accuracy about 3m. in my opinion skyhook and gps plus are needless if you have a working cb a-gps.

From my experience its the rom. As my gps worked fine with default FE3 (optus au) rom even indoors but when i flashed G5 (latest euro) i could only lock onto one sat outdoors even with skyhooks setting. Then i installed Samset 1.2 update.zip the gps works again, thats just my 2cents

For the record I haven't had any issues with GPS other than it being fair slower than my Milestone.
Didn't you sell your Galaxy S anyway?

Hey mate, I think I've seen you around the WP forums.
Quick question for you - I have a Milestone and am currently contemplating throwing it on eBay and grabbing the Galaxy S. Is there anything you miss from the Milestone?

The same here. The problems start when I go out and start to drive around in my car. My GPS is absolutely useless when you move around outdoors, but locks in a few seconds indoors.

Let me see if I understand this correctly. You have sold your SGS and you are still coming back here to crap on about the GPS and other small things which are only occurring on some people's phones and not others?
For the record, everything on my phone has been running silky smooth since day one. Lag only occurs with too many apps open and this is to be expected from an operating system that can multitask.

I sold my phone at a profit because currently i cannot afford to have unreliable phone in doing my job... then i searched for something better and can't find any.... so i'm still following the forum to see of all the problems i experience have been fixed .... if thats the case, i might buy another one....
and for the record, i didnt crap about the GPS, i'm just investigating it deeper, becase GPS is important for me...
Thats crap for you

Galaxy Tab GPS Not Working

I just got the T-Mobile Galaxy tab, and for some reason the GPS is not working at all... It shows the gps sign on the notification bar, but in maps, gps test, and gps status, there is no GPS data!
PLEASE HELP!
Thank you so much in advance,
Michael

i noticed that GPS perf is average indoor, if not below average. it is comparable to HTC Touch Pro, which is quite disappointing.
If you are trying from indoor, try to take it outside. many apps are saying that GPS works better when used with clear sky and i think it performs much better outside.

GPS is not working

I would make sure that I'm not using a case that has a magnet or any kind of metal on it. They interfere with radios and especially the GPS.
A couple of months ago I started using a Zenus case which has magnetic buttons. Almost immediately my GPS stopped working. It took me a very long time to figure out the real culprit. I tried rooting, changing some gps related files etc. None worked until one day when after accidentally leaving the cover at home I switched on the GPS - it started working.

Dude, you should update the maps in your galaxy tab. I updated already my maps and gps is runing smooth.

I bought a tab last week in Germany. The gps work fine in Germany, Holland and Belgium. But right now I am in Turkey and here it just keeps "searching" but never gets a location.
I wonder why and what, but I suspect location has something to do with it.

Galaxy tab Sprint gps not working!!!
hello i have a samsung galaxy tab (sprint) i live in malaysia,but when i on the gps it detect my location at hawaii plizz help me!!!

GPS not working
Hi
You definitely need to be outdoor for GPS receiver to obtain signal.
If indoors, you'll get signal if you have tile roof, not steel or concrete.
With a-gps, it might look like you are getting signal but actually, your device is using data to obtain location from cellular towers.
For best and quickest reception, enable your device's location and a-gps. Note, a-gps does not use lot of data, very little.

[Q] How is the GPS?

Hi Everybody,
I am very interested in purchasing the Tmo-US version of this phone when it is avaliable and I would like to know how is the GPS on these phones? How fast does it lock and for those who are coming from SGS, can you see a big difference in GPS performance? I am currently using a SGS vibrant on tmo-us and GPS is very bad on it. Thanks

better than thge galaxy s.
First time i used it it took like 10 minutes to lock on lol, but then each time after that pretty much instant (or close enough)!

Not perfect for mine, sometimes under the sky also cant lock any satellite or scan no satellite in car. But other people are getting pretty good result though. That's why i am not sure it's my problem or not.

I edited the gps.conf file for my location (not sure if neccesary, but had the file from my previous HD2 so figured wtf..)
gps locks in 15 seconds when outside

Mine is MUCH snappier than my previous HTC desire

Best gps I've experienced on a phone. Better than my omnia, hero and my wife's galaxy s, which is terrible

Thanks for the quick replies. I am sure with some new updates the performance will improve even better. I cant wait to get my hands on G2x now.

Also extremely happy with the GPS. Using MileageTrac everyday, and the GPS locks within 3-4 secs every time.

GPS is perfect. It locks satellites in 7-20 seconds. Accuracy is 5m.

so a few more uses and yeah still instant. thumbs up!

for those who got fast gps fix time, may I know what baseband are you guys using?

Can it be used for car navigation like the Desire HD? Anyone tried it?

I think I fixed mine.
Solution was (at least one among them)
- push appropriate gps.conf to /system/etc
- modify APN type of Mobile data to "default,supl"
- turn off wireless while aquiring GPS fix
My GPS now fixes within seconds with mobile data enabled.

Have any of you tried GPS Status? It helped alleviate slow-to-lock AGPS issues on my Incredible. If you launch the app, it forces a new download of the carrier's GPS file. GPS lock went from 2-3 minutes on some buggy ROMs to under 20 seconds.
It's not the most elegant of solutions, but it works.

yup, quite a few times works great.

I agree. Use it everyday. It seems more stable than the DHD with better signal lock.

The demo unit at the T-mobile store I went to yesterday had a horrible GPS.
It would freeze up google maps and wouldn't lock AT ALL when the satellite antennae was turned on.
With the antennae turned on, google maps worked, but the circle for your location was huge (obviously).

Were you trying to use it indoors or did they let you take it outside to test it out?

Did you try GPS on any other phones? Signal could have been bad inside the building.
Being a Vibrant owner, with all its GPS issues, I'm very interested in how the this works on the G2X before I consider switching.
Thanks.

Worked fine whilst I was out today. Only problem was a lack of a data connection.

Does the GPS accuracy suck on the incredible S?...please say it ain't so!!!

I need a phone that has a working gps. I have a samsung galaxy s, and gps sucks!!! I'm not talking about number of satellites, i'm talking about accuracy (on the app "gps test"). On my samsung it jumps around from 32 to 64ft accuracy and puts me on parallel streets.
Today a store rep let me take a htc incredible S in my car and drive around a bit. I was shocked to see that the gps accuracy was worse than my galaxy s!!! It found and locked onto many satellites (sometimes 11 of 11) but the accuracy sucked. It would fluctuate anywhere from 30 ft to 120 ft accuracy using the gps test app. At some points it would show me off of the road. Is this a common problem on this phone? I borrowed a friends motorolla atrix the other day and had an accuracy of 4.9ft! Thats accurate to like 2 steps! Would really appreciate your feedback. If your gps accuracy is good on your phone, then what do you think could have caused the one i tried today to be so horrible? Thanks

Nope not for me, but we're in different parts of the world. Mine's quite accurate and fast actually, with AGPS assisting.

Has always sucked for me in India.. then again I'm in the city and most of the time indoors
When I say it's always sucked, I mean it's always sucked for all my phones Incredible S does the same (quite so) lame job as my old Nokia did.. nothing to write home about. I just wrote that off to my region/country/conditions here or whatever
If I get it within 100m, I'm excited 4.5 meters? lol..

GPS accuracy really sucks on Incredible S. I've used HTC Hero for more than 1 year and never had any problem. Hero's GPS accuracy as sooo perfect. But I'm VERY disappointed with Incredible S. I've tried all possible ways, like calibrating the GPS, deleting and re-downloading a-data. But it's same. No improvements.

For me it works with no problems. Uk and Austria I used it in. Sometimes the lock times can be long, so I hardly ever disable gps, so it can collect almanac data. It is not a battery drag, it only uses lot of battery when it's active in the notification area. I use it to navigate on foot as well and I can tell it is seriously correct on location. +-1m
I had crap location info in maps and Igo myway only when the device was waiting to get a proper gps lock and only wireless location data was available which is useless for navigation purposes.

Maybe "GPS test" sucks? Works fine for me.

Same here. Was a Hero user before switching to IncS. I still have both devices so I tested them side by side. Hero is much better in every aspects, including lock time, no of sats discovered and signal strength. I believe IncS is limited by its antennae design.

From Canada here, and it sucks ass. My Samsung Tab works flawlessly.

Hahah yeah I'm also from Canada and this is the worst phone for gps i've had by far

odd, i'm from Canada and i've always had awesome gps accuracy and speed on a couple of htc phones. locks within 5 seconds and accurate within 5 to 7 meters.
you guys sure you are using correct settings? perhaps it's carrier dependant, although I doubt it.

GPS works fine here in Canada as well.. which rom are you guys using? I've noticed that certain roms cause me more issues with GPS but ARHD works fine for me!

It was equally bad on every rom i've tried.
Maybe it is location specific I'm in the east coast of Canada.
Also, the test something for me..
In location settings turn off location by wireless network and try gps only

@scooby
have u tried using the updated gps.conf file from the gps thread? I also have location by network setting off.

I never had an issue on my x10 though, or on sense roms if I chose wireless network location.
Now I still get nothing even when choosing wireless.

Just tested my Inc S with "GPS Test" app and I'm getting between 5-7 satellites and accuracy between 9.2-15.1 feet, from within the car. I'm running the latest OTA updated radio, with Hboot 1.16. Also, with Sygic Aura, got a lock within 5 seconds...I guess it depends on the location and radio version.

[Q] I9000 GPS not working sometimes

Hey guys
I have my mother's Galaxy S here, where the GPS has a special issue:
It often just stops working - in GPS test it sees and uses 0 satellites, in Waze and GPS Test etc, it does not say GPS disconnected, but just that no GPS lock yet.
Sometimes it would suddenly work and have a lock, only to loose it again randomly (in town, on open roads too).
We had it in 2 laboratories, both for some reason insist on changing ROMs, and the problem is not resolved.
The last store says that they cant guarantee this problem is fixable, and that Galaxy S from all countries is known to have very weak, problematic GPS.
Does this make sense? its hard for me to believe, and sounds more like a cover-up for their inability to fix it..
What do you think? anything I can do? other than accept that this phone is doomed?

Best GPS Fix for Samsung GT-i9000 Galaxy S

That actually doesn't work for me...
My GPS requires me to have an active internet connection when I search for satellites, for some reason it's impossible to get locks on more than one satellite without
