This may be old news for many of you, but I just found this last night so I thought I would share. The flashable update .zip from the linked post worked wonders for my Captivates GPS.
Here is the original post: http://forum.xda-developers.com/showthread.php?t=782242
I flashed the file from clockworkmod recovery and my gps is markedly improved. It's not perfect but it is much better.
Just thought I would share this with those who didnt know about it.
I also attached the file that I used.
Just for references sake so that we are comparing apples to apples, I am using JH7, rooted with unhelpfuls 1.4.1 kernel.
my mistake. i reset the supl to auto config. I also realized that clockwork uses the internal SD as default so i was reinstalling my root update.zip i still had on the internal. I was trying to install without clockwork in the beginning so i just renamed it to update.zip and threw on my external 16gb but it was installing update.zip from my internal. It works great and i have a great lock within 6 seconds when I have never seen a lock on my device. I even rebooted a couple times to get my lock right away.
Thank you again!

Thank you for making this thread. I do not follow the vibrant section too often so I was unaware of this. Thanks for bringing this to my attention OP
Awesome! Glad I could help even a few people. I knew I couldnt be the only one who didnt know about this!
just an update. Overnight, the GPS magically stopped working again. I havent been able to get a lock at all and have a max of 4 sat. connected at once on a sunny clear day. Any ideas?

Is wifi on? Wifi on its way hard too lock. Or try the Ms based trick a few pages back or the thread itself .. if wifi was on, exit maps or GPS test completely and turn GPS off, then turn GPS back on and try again......

Really? Turning off wifi from the get go is a hassle ? Just pull down turn it off, done. Just if you do it while its on gotta exit and do again. Semi annoying but not and a half.lol
Im starting to think that my phone is damaged I have never seen a lock, I have used every method and nothings works

Wow this worked great on my phone. Locked on quickly and gave me the best accuracy I've seen. Gives me hope on an official update for our captivates.

Mine stopped working as well as when I first flashed but still works much better.
I used the LbsTestMode hack to change to the supl.google.com settings and it helped it a little more. Like I said in the original post, this isnt perfect, but its still an improvement over stock and it gives me hope that this is correctable via software. I had all but convinced myself that the hardware and/or design was faulty.
-D
I dont remember what i did but the gps is now working again and it works great, even from inside sitting near a window. I know that it is a result from these files posted. I also set all my settings to :
Application Settings
session type: Tracking
Test Mode: S/W Test
Operation Mode: MS Based
Start Mode: Hot start
Gps Plus: On
Dynamic accuracy: on
accuracy : 100
skyhook: on
pc tool: off
SUPL/CP Settings
Server FQDN: auto config
SUPL Secure: On
AGPS Mode: SUPL
I hope these settings can help someone else. I dont know why my gps cut out before but after flashing the OP files and changing settings to these, I can get a lock indoors without WIFI on.
Also i never have wifi on unless I am in the house using youtube or downloading stuff.
Thank you again for the files! I was using my GPS all day with no issues. I owe you big time because my phone never saw a satellite lock before flashing these files.
---------------------------------------------------------------------
EDIT
---------------------------------------------------------------------
I was having issues again today and changed to supl.google.com with 7276 i believe and it works perfect now and has been all day. I lock within 5 seconds of opening google maps. I now dont care if they ever release a GPS fix because mine is perfect and I wouldnt change it.
I would like to start a thread to discuss what is the optimal GPS setting for the Captivate after installing the update. From what I can see, the update didn't change my LbsTestMode setting at all. My GPS is now working pretty well, still can't compare to the HTC Aria I had before but acceptable. I wonder if we can further tweak the GPS setting to make it work better.
the only change i seen was if you check auto config it takes you back to server port 7275 and changes the server to a new one.
yesterday there was a thread started about those who got the update successful, and the guy did a test of his gps with screen shot. A) how do you track your route, B) how do you take a screen shot?
it looked like he was using the maps app but i looked all over it for a way to track my route!? thanks..

It seems that most people who had messed with the GPS settings before the update are not getting optimal GPS performance after the update (This is true even if they change the GPS settings to stock original that shipped with the update).
So moral of the story is to change GPS settings to stock before you update....?

My GPS doesn't work at all for some reason. I don't know if I have a totally defective phone or the update didn't have anything at all in it that fixed the GPS. I'm ready to just give up on this phone having a working GPS.

Did you change your GPS settings prior to the update? If yes, welcome to the "group"
My GPS is definitely working better after the update. It used to take 30 second - 5 minutes to get a fix. So far I have been able to get a GPS fix within 15 seconds.
My settings are:
Tracking
S/W Test
MS Based
Cold Start
GPS Plus On
Dynamic Accuracy On
Accuracy 50
SkyHook On
PC Tool Off
supl.google.com
Port 7276
Secure Socket Off
AGPS Supl
As far as tracking my position with driving, it's not perfect but acceptable. At time the GPS would put me on the local street next to the freeway but not too often. It takes about 30 sec to 1 minute to locate me while indoor so I have no problem doing my FourSquares checkins.

Actually, I never touched my GPS settings prior to the update, and I get crappy tracks. I had a Captivate which I changed the settings on, but then I ended up exchanging it for a new one a couple days before the update, and left it exactly as I found it, and GPS is spotty as hell.
First of all, I'd like to thank you for posting this thread, it's exactly what I have been looking for. The other threads keep getting hi-jacked by people who couldn't get the update. Hey you knew when you rooted you wouldn't be able to get OTA updates, get over it and wait till someone figures it out.
Back on topic, my GPS is definitely better. I did change my settings before the update in LbsTestMode to the recommended settings. My gps locked quicker, but it was constantly losing the lock. So i used the shortcut method to go into LbsTestMode and changed back to stock settings. It was like the phone was set to lock at exactly 30 seconds, 30 tests with an average of a little under 30 seconds.
The accuracy was a little worse, 50m compared to 15m. But it was also losing the lock quickly, so I changed the spirent setting to supl.google.com. Now i lock between 10 and 15 seconds and it stays locked. My settings:
s/w test
standalone
hot start
gps plus- on
dynamic acc. - on
accuracy- 50
skyhook- on
use pc tool- off
custom config
7276
secure socket- off
agps- supl
So maybe the answer in the end, sad to say, is to buy an aftermarket gps device with bluetooth integration and bypass the built-in gps altogether.
I've been messing with the gps all day and cannot get a lock at all. Not even for a second. Messed with my gps settings before the update.

Two months in and I've seen hundreds of threads about the GPS on the captivate, The GPS its broken, no good, damage. Lets get over it and move on. We [email protected]$k BTW new update its a lil better but still sucks. My nexus one located me with no problem spot on. Change your phone why u can. I wish I was under the 30 day return policy.

The only settings I changed were the server before the update. I checked the settings after the update and I had Server as spl.google.com and Standalone in Operation Mode. I switched to autoconfig and those changed to some new server and I changed Operation Mode to MS Based as in jaimingandhi's link. Before I made those changes it took about 3-4 mins to lock on, now it takes about a minute, so not 15 seconds like others have said, but better. Will do more testing later. I count for two as I've got to Captivates at home. But it looks like different settings work for different people.
Edit: Tried again today, lock takes still 3-4 minutes and loses it constantly and there is no accuracy of location whatsoever.
I updated successfully and still had issues with GPS locks until I powered down my phone, removed the battery, sim card, and external sd card, replaced them, and then rebooted the phone. After that I was getting a GPS lock in 15 seconds or less and not constantly dropping signal as long as I had line of sight to the sky (a.k.a. through the windshield).
How to fix the gps on the Samsung captivates GPS.
Insted of MS Based use MS assissted
Lbstestmode -> application settings -> operation mode-> MS Assisted
Let me know how it gose

*facepalm*
This does nothing. It makes it marginally better at best (read: not better at all). If you're really having that much trouble, flash to KB1 and use the PlumbBob GPS fix. Those ACTUALLY do something.
For most your suggestion will give them the most lag and least accurate GPS positioning.
I suggest you in stall Adams GPS fix to your phone, that or use ga_D's. (gadnarf_gpstweak_att)
Both are much better than what Samsung has provided...
There is also plumbBob GPS fix, but when I tried his version 2nd Beta 6, my GPS only saw 2 sats with no locks even with 10+ minutes of waiting... I did not try version 1 of his fix.
As for the GPS settings, use either Standalone or MS Based(some drift with this setting, much less than ms assisted) . Set your support server to google, distance to 80 and good luck...

MS Assisted = uses cell towers only to determine position. Intended to be used for 'dumb phones' that are not GPS equipped or where only 'coarse' location data is required.
MS Based = uses cell towers to provide approximate location for initial fix, then GPS thereafter.
Thing of it is, Samsung's configuration interface for the GPS is so silly that changes in LbsTestMode don't always really affect anything. If you're getting good results after applying this 'fix' it's just coincidental, or perhaps that you'd finally used GPS long enough to get almanac and ephemerides downloaded over the satellite signal and your GPS was able to function unassisted.
What about this has anything to do with development?

2.0 is in beta. It's still in development and is very much a work in progress and still has some issues. 1.0 is stable.
Thread moved.
Plumbob GPS fix works.
After flashing continuum, my gps works great (for this phone ). If you check the OP on Continuum in development, it says which gps fix cezar used.
Sent from a place my wife doesn't know about (yet)
After flashing Andromeda v3, the gps works great! Gets a lock and STAYS locked for once!
My personal experiences with MS Assisted and supl.google.com etc are that it works great for a few days... Tracking and all. Then you start to only see satellites and never get a lock...

I decided to make this a separate post...
My original phone had all sorts of trouble - GPS was the worst. I don't know what my original one was, I do recall I'd applied the OTA update that was supposed to fix the GPS issue - it didn't.
So I got a warranty replacement phone - it worked fine out of the box, but the next day it was doing the same old crap.
This one came with the OTA update pre-installed. It's a "1010 rev. 0.4" if I'm reading the sticker under the battery correctly...
I read countless pages of stuff online, tried various "fixes" that were posted, all with similar results.
One discussion I read was posted by a guy who claimed some GPS expertise, and indicated that the problem was in the driver - to paraphrase from memory it was something like the cache was getting corrupted and the HW/driver wasn't cleaning it up.
He basically said that they needed to write a new driver, but until hen you could use a 3rd-party app to clear the cache and re-download clean data from the satellites.
I found a (FREE!) app called "GPS Status & Toolbox" by author "EclipSim" (Disclosure: I have NO CONNECTION to this guy, just like his app!)
It has 2 menu options:
"Tools -->Manage A-GPS State-->Reset" and
"Tools -->Manage A-GPS State-->Download"
After doing those, it will usually grab a fix within 15 seconds at most. Once it's "timestamp" is updating every second (you'll see, in the app) I can then switch to Google Maps and it too will get a fix before too long.
Another nice thing about the GPS Status app is that it shows you how many satellites you "see" vs how many you're connected to. When it only sees one or 2, or when it sees a bunch but isn't connecting, you can be sure you need to reset/download again...
This thing DOES eat battery - so it's a good idea to be plugged in, or to kill the app once you've got Maps working the way you need it to...
Yes - it's a PITA to have to do all this to get a basic function of this high-dollar phone to frigging work - but it beats having it NOT work...
Hope this helps someone!

Tested again last night on two rides. Worked great even sitting in the cupholder. Major improvement over my original Captivate which was returned for speaker problems.
not really much better for me.

Plumbob didnt do much for me. I am pretty well convinced that with the utmost optimization, the crappy hardware in the captivate can operate marginally well at best.
Ryans Plumbob fix does work. Its a much better improvement over stock on defected models. I had a 1009 and it worked great but the tracking and navigation were still buggy unless the phone was placed on the dashboard. (Always had a larger blue circle and would skip at times).
Finally gave up and noticed that the local atnt is a device service center. Went in and got a refurbed 1008 with stock 2.2 and the navigation is excellent. Even sitting in my lap...
I mean you all should still have the 1 year warranty. Just find a service center and exchange your phone. Hell the refurbed one I got was in better cosmic condition then my original.

i know everyone will tell me im wrong but try running the samsung gps restore app once then remove it from your phone. it is free in the market. and i assure you t doesn't revert to stock settings. atleast not in any location that i am aware of. i have checked the jupiter .xml and secgps.conf and lbs test mode before and after running the app and it doesn't revert anything. but it does seem to clear errors that may be caused by messing with settings without haveing a proper jupiter.xml or config file first. for instance on old roms if i chose msbased mode in lbs test mode it would work for 6 minutes and turn off. even after reverting the settings and clearing gps data the gps would turn off after 6 minutes. running gps restore or doing a factory reset were the only two things that would make my gps work again.
also yes google maps and captivates dont agree with each other 100% of the time. it is thought by some that the gps is recieving interference from the cell antenna (that's one theory at least) so the more data you use as you navigate the more issues you might see if that is true. try a gps app that downloads the maps to the phone. it takes up alot of space but if the app agrees with the phone it is worth it. in the past i had trouble with some aftermarket apps as well while others swore the same apps had solved there navigation problems, so try a few and find one that works. navdroyd is great on my phone.
also, though people are raving about plumb bob's fix, i have more blue circles with it. the problem is the msbased mode. it doesn't work on my phone very well. (back to the data/interference theory) i instead use Da_g's fix the control plane version with lbs test mode supl settings set to control plane and i turn off dynamic accuracy. and i use the kc1 modem. there are other modems with good gps but kc1 has the best call quality of them.
Hi to everyone,
I recently obtained an i9003 (It was probably manufactured a year ago, however I dont know to check it). I'm very happy with everything but the GPS.
I know that it has been debated a lot, I read all guides on this forum and others, I followed this one:
http://forum.xda-developers.com/showthread.php?t=1069416&highlight=gps+improve
and then tried with this one:
http://forum.xda-developers.com/showthread.php?t=1032034&highlight=gps+improve
I even installed GPS Aids v2 (but my phone is not rooted!).
I tried this fix (the piece of paper to put pressure on the antenna):
http://forum.xda-developers.com/showthread.php?p=13133654#post13133654
Then I decided to open my device, and modify for the connection between the antenna and the board, like explained here for a similar device:

You cannot say that I didn't use the "search" button
So far these changes were not successful, at least the performance did not change perceptively.
Near the window, in a tall building (6 floors above) I don't get any satellite on view, on the balcony I get 3-4 at around 30dB (and I get a lock in with a very poor accuracy, like 300feet). Is it normal that the number of satellites is so low? I was wondering if the LTO file is the correct one, it is called north-america and I live in Europe... Is it normal?
Do you think that rooting my phone would help? I'm happy with the stock ROM so I would not like to root it just for fun.
Which additional info do you need to help me?
Thank you very much,

Getting 4-5 sats in a balcony is perfectly fine. Doesn't mean hardware problem. But getting a fix using only one view of the sky is difficult.
Gps fix needs 3 sats minimum to get a 2D fix (without altitude). But the sats need to be well spread to get quick fix. Accuracy of 50 mts is best u can hope on non-us-military devices regardless of whatever accuracy reported by software or others.
Try a location where sats hav about 90 degrees seperation or more. Remember just 3 good sats are enuff. Most of the time gps rejects data from other non-geometrically-optimul sats.
Let me know if this post is any help.

My question is what is the max number of satellites were you able to lock given all ideal conditions, for me the max was 4 (took 5 mins to reach this figure under open sky) on this phone while Xperia arc and HTC wildfire were able to lock 20 satellites from the same location. Is the GPS on phone really a piece of sh1t ? Just confirm this and I am prepared to sue Samsung in consumer court over this.
Adding to this, while traveling in a vehicle the other two phones (mentioned above) were showing realtime progress of the vehicle on the road, whereas Galaxy SL was highly inaccurate and even the wrong position shown was not updated constantly.
In stock condition of d phone, GPS is really a piece of sh1t....

gps fix
hello
I hope i am in the good discussion,i am not very confident with the forum.
I have now 2 i9003,ifound the gps was working like my stand alone garmin gps,taking sometime a long time to fix some time not ,depending of the time it was swithed of or where i was.Like a gps without Agps.
So what i did is:
go to setting with dialing on the phone *#* #3214789650#*#*
I did some test and now for me it's obvious that the operation mode in application should be "MS assisted" (stand alone means that it doesn't use at all the data network to help for the first fix)
accuracy should be put at 100 ,it doesn't means that it will be more or lest acurate,i understood that if the value is lower that this it give data to your application(sygic or other).If it goes over 100 you will get something that "waiting for valid signal"
There you can do some test like i did :
-put opération mode to "stand alone"
-go back and "delete gps data"(so no satellites history)
-get position test ,in that case it can take 15 min to get a fix depending where you live.
go back to setting:
-put operation mode to "ms assisted",so it use satellites and network for the fix
-go back and "delete gps data"
-get position test,in that case it take less than 2 min.
If it's not the case check :
-go in supl/cp settings ,check the serveur ,i don't know if we can put the same serveur all over the world but i think yes,for me it work well with the default one
supl.google.com port 7276 ,secure socket off,agps mode supl
-remember you need to enable data in android menu :wireless and network,mobile network,network connection enable (that a traduction of my french menu)
for info,i have the original rom xwkb1
I hope it helps.For me it was night and day,now it works as well as my desire which was very good.
I just forgot to mention one thing,if you switch data to wifi and go inside house through a router,i think agps cannot locate you with the network,so they can't send you data,not sure about that,but that's the way agps works.(so no wifi)
For the 1st time i use GPS in SL.. I waited for 10min or even more with the orignal server which set to north america.. And i tot the gps for phone is so always like that.. but when i see this forum gps fix.. i just "whoa".. i dont even know there is gps problem in my phone..
SO.. i str8 root it.. flashed to XXKB3..
gps fix set to Asia.ntp ( i from Malaysia)
and i try get sattelite signal from outside of my hse with clear sky..
LOL --> result : none.. get 3 satilite but didn't lockon even with my wifi switched on
and then i go download gps aids .. switched on my wifi download the LTP file.
and try get sattelite signal
Result: 10GPs in 10 second and lockon immediately
I open my papago.. lOL.. position fix..
I didn't touch anything on the SUPL setting or standalone or wat
I didn't even go open my phone and put aluminium foil
Just like that..
GPS fix.. I think the gps aids is to use for searching satelite signal and lock on your position.. so when u open up the papago.. it will str8 lock on your position without waiting 10min or more..
Haahah..
edmund~ u r right!

Hi everyone!
For some time now I have been researching on how to make my GPS on my phone (Samsung Vibrant T959 Froyo 2.2) work the way it should. I have tried everything with failure until a few months ago.
I wanted to share my success with everyone. I know this GPS bug has been a thorn on everyone's side.
I do hope this works for everyone who trys it. If you have my phone it will. If you have a different phone it should
As of today I finally found a rock solid configuration that actually works and I would not be posting my findings on this website if it was not a solid fix.
It does involve going into the phones GPS settings. You will only need to do this once. I have tested this only on my Samsung Vibrant (T959) for over 2 months. As of today I still receive 12 satellites with 5 to 7 fixes. For the first fix ranges from 1 second to a Max of 15 seconds. Accuracy ranges from 10 feet to 37 feet. Remember, this is inside my home and not outside. Outside is even better of course.
If everyone who trys this please post your findings along with your cell phone info. This way anyone who reads this can possablity benefit from it.
GPS FIX For Samsung Vibrant Galaxy S (T959):
Please follow to the letter.
Update your phone to froyo 2.2 if you can. I don't think its necessary.
Go to your dialer and enter
this line below
*#*#3214789650#*#*
You should now see your phones
menu(lbstestmode).
Select - Application Settings.
Check each setting and match
To what you see below.
Session Type = Tracking
Test Mode = S/W Test*Operation Session Mode = M S Based
Start Mode = Hot Start
GPS Plus = On
Dynamic Accuracy = On*
Accuracy = 100*
GPS Logging = Off
Go back once. This will bring you back to the main menu.
Now SELECT SUPL/CP
Match what you see here to the
settings you see on your phone.
Server FQDN Type
= Custom Configuration
Server = supl.google.com
Server Port = 7275
Secure Socket = On*
AGPS Mode = SUPL
Now go back until you see your dialer or home screen.
REBOOT YOUR PHONE!
Go into the Android Market and Search for Samsung GPS Restore.
Download and Install GpsRestore.
Now search for GPS Doctor. You will need to purchase this. If it does not work for you, you can get a refund as long as you quickly do the refund. I used the purchased one which I know works.
Once you install both apps run GPS Doctor first! This must be run first. Run this first then select manual fix. Do all three options first. Then select advanced operations and run each one. You should only need to run this once. Close out gpsdoctor.
Now run GPSRestore. Once you get all green, then your done.
REBOOT
Then
REBOOT AGAIN!"
Check out your GPS useing any or your GPS apps.
I hope this works for you. If you have a question Ill be glad to help.
BTW I do not own any of these programs or promote them.

Nothing short of amazing! From no locks ever from where I sit indoors to a fix on 6 birds within 5 seconds!
Many thanks.
Wow. It's only taken a year for someone to figure this out. Maybe Samsung should put you on their payroll.

Thanks so much! Been tired of the horrid GPS lock speed. A hot lock sometimes took a couple minutes, but ran a test overnight and it on average took 15+ minutes...
