I just tried it and I'm not sure it worked. When I went to google maps it did jump to my position but the GPS icon at the top was steadily "bouncing" or whatever you want to call it. I went to the Lbs GPS test and it showed it seeing 6 satellites but never locked and didn't show any long/lat info.

OK, went back and turned off Skyhook. Not sure what effect that might have had but after retesting I got a lock in under 30 seconds and accuracy is at a consistent 16.4 feet. What kind of accuracy are you all seeing? Please post.

What I've done is change my settings back to default but with the supl settings set to auto. It takes about 90 seconds for me to get a lock and accuracy hovers around the 10 meter mark. With skyhook on I get zero locked satellites.

Every thread on every forum seems to have a different combination of settings, all with mixed results. I'm wondering if any of the settings are really making any difference at all, or if everything is just coincidence (ex: was able to lock instantly after changing settings, but that's only because you had a previous lock a minute ago, which allows you lock on faster).

edit: Someone also suggested somewhere that maybe these settings may only affect the GPS test application within the console, and that they aren't permanent settings that affect the way other applications (e.g. Google Maps) work.

Ahh, the famous Placebo App! LOL, guess we need an uber geek to do some verifiable testing on these solutions, find what WORKS and report back. Samsung? Hello? Tap Tap,...is this thing on?

Yeah I definitely agree that different settings work for people differently. If the GPS still doesn't work then I would say return it because I was about to do the same thing, but make sure the GPS is working at the store as soon as they swap your SIM!! lol

=(
Using this with sky hook on enabled me to get a lock indoors where as before I was getting no lock any where around my house. whoohoo!

Can anyone confirm if skyhook uses data? I think it does, but I won't have the phone until maybe this weekend, but I have new 2gb limit

I think you are over-estimating the data-usage of this...


The only thing that will ever get you near a 2GB limit is downloading files, podcasts, streaming media, downloading game apps, downloading hundreds of full theme packages / ROMs / etc, using google maps & street view everyday for 1hr or more every single day, re-downloading all your dropbox or evernote files about 50+ times (why would you ever do that when it syncs well), etc...

That's all I could come up with off the top of my head...

And you can check data by dialing *DATA# and hitting 'call.'

Sad No GO

tried all suggestions on Forum and no go.
Att said do a 'Hard Reboot" but were unable to tell me how to do this.
When I try Google maps shows I am about 15 miles away from my actual location
and 'searching for GPS" continues till it times out {am doing this outside}
am in Maine and thus far from satellites
maybe as I've seen AT&T are only allowing phone to log onto a few satellites to save battery.
Back to AT&T tomorrow doubt they will solve problem so I guess it's back to i-phone
urg !!

Got my phone today and installed google nav. I couldnt even get a lock on any app that required location in my house. I went into the menu for the settings. All I changed was skyhook to on and rebooted. I tried google nav and maps and it locked on within 10 seconds in my house.

Good. Its seems that very few devices work right out of the box. Almost always some one changes something and it starts working. So weird. An article did say that the captivate and vibrant come with broken gps but its fixable through firmware update

I'm really starting to believe that all these "fixes" are placebo effects. I did a hard reset this morning, so everything was reverted back to factory settings. On the way to work, the GPS was acting up as usual. But during my lunch break, and on my way home, the GPS was damn near perfect. Locked on within seconds, was extremely accurate, and never lost its lock. I made no changes to the settings at all. So improved performance was really luck of the draw (It'll probably act up again later). But had I made any changes before my lunch, I would've thought "wow, these changes really worked!!!"

If any of you can say that after you made your changes, that the has GPS never acted up again (but give it at least a few days), I'll believe that those settings really made a difference. But at this point, I'm thinking it's just a placebo effect.

Going to wait for an official fix myself. Only real problem I've had since I haven't used it for directions yet was the clock/weather widget I'm using. When I go to maps in my apartment it locks on just fine. I turn the phone and the arrow moves smoothly and what appears to be accurately in comparison to the direction of the main road just outside my window.

Changing the settings can change the way the phone attempts to receive gps signal so messing around with them may actually help. They arn't there to just look at...so i dunno if i would go as far as saying its rubish

I think changing these setting can help, but as has been pointed out in the xda forums this is just trying to make up for what appears to be bad gps firmware. Using gps testing utilities you can see that the phone is only locking on to at most 4 or 5 satellites, where other phones will lock on to twice that many. The settings may help it lock faster, but to really fix this problem there needs to be a firmware update to allow the gps to lock on to all of the satellites it's seeing. This isn't just a captivate problem either. It's a problem on the vibrant and the international galaxy s phone as well. We need samsung to do something about this. I would suggest contacting samsung anyway you can to make them aware of the problem.

I was planning on returning my phone for a replacement to see if this GPS problem was limited to the phone itself. Tuesday was the last time I got a GPS lock so I thought it was more serious than some others in this thread.

Since I rooted my phone I removed the root and did a factory reset. When I took it up to the store - guess what happened. The GPS locked on and worked just fine so they just handed my phone back and said there was nothing wrong with it. I'm betting it will revert back to not working again soon.

After a lot of playing around, I have found out that this change from Standalone to MS Based mode, and the change from spirent server to google has made no difference in terms of accuracy of the GPS for me. My outdoor GPS Based accuracy was always good (5 to 10 meters) when there were sufficiant satellites the phone could see and use. My Wireless network based indoor location has been, and still remains, a giant half mile circle not usually centered around me.

Since I don't get any benefits or detriment from this change in terms of functionality, is there any downside regarding data usage and battery, with an MS Based mode over standalone, that would make me revert back to original settings?

It was suggested in another forum that *#*#1472365#*#* is simply a GPS testing application, and that all the changes you make in there only affect that application. Given my experiences with the changes, and the fact that there is no single combination of settings that everybody agrees upon, and that every single combination has mixed results, leads me to believe that it has no affect whatsoever. Any "improvements" in performance were just coincidences (would've happened even if they didn't change any settings).

You can test your GPS in different modes.

But the settings are not relevant for other applications.

It is a simple illusion that it helps to manipulate this settings.

GPS is very time-dependent.

And:
I don't know where we can change the default GPS Mode/s...

I'm getting really upset about this because I use GPS alot and it doesn't work. I suggest everyone tip Engadget and the other sites about this so maybe the attention will put some fire under Samsung's butt.

This made perfect sense to me, because whatever I changed there, I saw no effect. My results did vary over time depending on how many usable satellites the phone saw, but the GPS Test in *#*#1472365#*#* saw the same thing too. What I did see that the phone was very picky in terms of which satellilites it would use (which might be normal, thisi is my first time testing this).

I think we might need a firmware update for the phone to use the satellites more liberally. That, and a change in algorithm to improve the accuracy of the cell tower based calculations is what we really need.

I leave mine on all the time since it only gets used when an app calls for it. I hate having to turn it on just to use an application

I've been using Google Navigate almost exclusively for GPS testing since it is the app that I plan to use the most and the GPS test data from the configuration program doesn't mean anything to me.

The first time I tried GPS I gave up because it was taking so long to find a connection when I was standing in my backyard. Based on a forum post here I turned Skyhook on. Later that day I managed to get a GPS signal after a long wait while I was walking outside and then successfully drove to work with turn by turn directions. Next I tried navigating home that afternoon, and again I had to sit for a while for the GPS signal to pick up. I tried navigating to work again the next day and still took a long time (several screen timeouts) before getting a GPS signal.

Then I tried the settings in the XDA post linked earlier in this thread, and the next time I went home it found my approximate location (half way across the parking lot from where I was) pretty quickly and it caught up to where I actually was before too long. This afternoon I used it to get to lunch and again I had a quick lock and good accuracy. So, even though some folks think we're having placebo effect, as far as I can tell there was definitely an increase in GPS usability after using the XDA settings.

My wife also has a Captivate and we haven't had time to play with GPS on hers yet, but when I tested it out of the box it also experienced a long delay before obtaining a location. This weekend I'll put them side by side, hers still with stock settings, and see how they do when we're driving around running errands.

I had similar experience to no driver. It went from not being able to fix a location to being able to do so within a half minute (although not with the accuracy I experienced even with my bold 9700). But its usable for now, and hopefully a firmware update will make it 100 pct.

How can I tell if I'm locked and what my accuracy is? I currently have a blue blinking arrow and a blinking "satellite" dish in the task bar. Trying to you googlemaps.

push on the blue arrow and it will tell you the accuracy. If you dial *#*#1472365#*#* you can test the gps signal and it will tell you how many satellites you are getting a lock on

Not sure what to make of my GPS. Put it on the passenger's seat, you get a very strong signal and it locks on like 7+ satellites. Move it literally 2 feet to the left, onto the driver's seat, and all reception is lost, 0 satellites.

Needless to say, my Magellen Maestro and my friend's iPhone 3G work anywhere in the vehicle with strong GPS reception.

It also seems to lose satellite reception if the screen blanks...? Geez.

I used the "supl.google.com" method, but turned Skyhook "ON" instead of leaving it "OFF". It is locked on, and very accurate. I even went to work to pick up my check (on vacation, THANK GOD) and tried it out. It worked without issue and new exactly where my car was.

Tried all the settings and nothing really worked. Sometimes it would lock on in under 30 seconds and sometimes it would take minutes. Still have 20+ days to decide if I want to keep this phone or not but this is a huge issue for me. I'm disappointed that Samsung hasn't stepped up to the plate, especially since the Galaxy S line was released in Europe a bit earlier and has the same issues.

Default DAMN you Samsung!

So the fix "worked" I can get a lock pretty well and the LbcTest shows an accuracy of 5 meters (which is AWESOME) but then when I go to googlemaps, that 5 meter accuracy shows me a block and a half away.

I am calling Samsung on Monday to make. I encourage everyone who is having issues to do the same! If this isn't fixed within my 30 days I will be returning the phone I otherwise use. I am just too dependent on my GPS. I use it all the time and it needs to be accurate and lock quickly.

It may have been coincidence, but I seemed to have a better time keeping a lock this evening when I started LbsTest and kept it running as I used google maps. I still lose my lock almost immediately after going inside my house but that is to be expected I suppose.

On google maps my accuracy jumps between 5-10 meters, my blackberry would also do this as well.

Is it actually that accurate or is it just saying it is that accurate (when it's not) like mine?

Check your charging cable?

I tried everything on this forum, and finally this worked (although I had also set Application Settings->Accuracy:20); I am now getting excellent and fast accuracy on GPS...*except* when I am using my AT&T car charger. I tried this about 10 different times, and my GPS locked on when I was not charging, and stalled when I was using the car charger.

Any thoughts?

I went running today with Runkeeper and the GPS was all over the place, unlike when I used Runkeeper with the iPhone.

I've had no issues with my car charger but it is a motorola charger (from my Q). The GPS is equally bad with or without it.

After playing with this for two days and trying every setting combination on every forum and trying a few of my own I am confident that I have found what works best for my phone.

Here are my best settings:
Application settings-
Operation mode:MS Based
Accuracy:20
Use Skyhook: On

SUPL/CP settings-
server FQDN type: custom config
Server: supl.google.com
Serrver Port: 7262

Everything else is left as default.
This gives me a lock within a minute or so while outside. If I've gotten a lock recently, it is much faster to re-lock. Accuracy isn't great but it is good enough for Navigation. Not good enough for geocaching, golf, running, or hiking though.

If it doesn't get any better, I still think I will take the phone back and look into breaking my contract and going to Verizon... They have some cool Droid Phones and they don't have GPS issues.

Also, at one point I had a 7 satellites in use. That disproves the theory that the hardware is only capable of using a max of 5 satellites at once.

It's right on! My house is at the end of a block and this shows me off the street and actually in my house which is a ways off the road. So it is def. accurate and google navigator works like a charm im located in the chicago subs.
