If you use a program like visualGPSce, you may notice that you can see lots of satellites, but you can't get a fix. I managed to fix it by:
1) Setting my log file to 3200bytes (using advanced config)
2) Disabling aGPS
3) I then turned off the phone, took out the battery for 10-20 seconds and replaced it.
4) Ran the quickgps program
5) Managed to get a fix and have it working quite fast!
I don't think all of this is necessary, but I have a theory:
I have a holux gpsslim 236B and sometimes it exhibits similar behaviour if you send it screwed up commands. The way to fix that was to remove the battery and then open the case to short out the backup battery (Yep, they were so helpful in enabling it to "remember" your corrupt settings). Reassemble and the gps device works fine. I get a feeling that the raphael may also benefit from such treatment (a forced reset on the gps module).
The only other theory I have is that the gps log file was corrupt (I couldn't delete it so I just made another one) and maybe that fixed it.
I've only given it limited testing, but if it breaks, I'll let you know so you don't waste your time!
I noticed my GPS performance was much better when I set my gpslogfile to 32KB as opposed to setting it's size to 0.
Just my 2c.
Isn't the quickgps tool for agps?
So either the disabling of agps or the quickgps is not necessary

what's the logic/reasoning behind adjusting he gpslog file? i occasionally use GPS/tomtom though i would probably consider using it more frequently if getting a signal lock didn't take anywhere from 5-15 minutes.
i currently have disabled agps (no data plan so it's useless anyway) and have no logfile set to 0 as per the suggested settings i saw on fuzemobility.com post.
Can you post the file you used to load QuickGPS? I tried to download one but could not get it to run on my XDA Serra.
@kimbja98
how long has it been working? get back to us after a month or so of solid performance... the GPS issues seem to be so random that doing almost anything can seem like it fixes it... but i hope you're right
Just used it on the train on the way into work and it was fine, took about 2 minutes to get a location.
One thing I think may have been the problem is that it thinks it should see X satellites but obviously can't and gets confused (even if there are others in clear view), which may be down to agps, quickgps (I'm not sure if they're the same thing) or corrupted log file but now those satellites it can't see get dropped from the list (you can see this happening in VisualGPSce) and it gets a location after about 5 or 6 have been found. The holux seems to get positions at 4 (which theoretically, is the minimum but could be done with 3 if altitude is negligable) but that uses the sirfstar III chipset...I don't know what the raphael uses though.
I should mention I use ROMeOS 1.40 and that may have something to do with it. Either way, I'll be giving it some fairly rigorous testing. If it does break, I'll know how long it took and it may be that the log file got full and if it that, some regular deleting may be called for.

YES, your method seems to be one of working the best.
Congratulation.
I use the mix of some methods in the forum, and my GPS reception is quite good, even in my room inside!!
MY CONCLUSION:
1. to get rid of useless stuffs from the system (which also bad for the sat reception), use
[ROM] [WWE]RAPHAEL WM6.1 V05 - Build 20758.1.4.1 - pdaviet.net (http://forum.xda-developers.com/showthread.php?t=438488&highlight=20758.1.4.1) and
[RADIO] Raphael Radio 1.02.25.28 (http://forum.xda-developers.com/showthread.php?t=437219)
(before installing these ROM, the first step should be installing the HARD-SPL to save your device (http://forum.xda-developers.com/showthread.php?t=410150)
2. to get a really quick fix,
take the battery out, as mentioned above, for a few minutes, to clear the GPS memory. (You can try for example igo now, you will see nothing on the sat view at this time...).
After that download QuickGPS data (the ROM I mentioned has a correct quickGPS data download!) If you see iGO sat view this time, you will see a lot of red dots immediately, and after a not too long waiting, you'll have fix)
3. to make the GPS even faster,
adjust the baudrate to 38400 (with comport4) in your navigation program. (But leave port4 and baud4800 settings in the Windows Mobile settings!!)
4. there could be some navi software, which couldn't get fix (iGO yes, for example Googlemapsmobile not every time), use GPStest (http://www.chartcross.co.uk/products/WM00002_details.asp), select com4 and baud 38400 also, minimize, and run the other navi. It WILL work!
5. after getting a fast signal, in order to get rid of lag while navigating, use this excellent method from the forum:
A. With Advanced config 3.2 http://www.touchxperience.com/fr/out...ol-32-cab.html
1. disable A-GPS
2. disable GPS logging
3. logfile name must be empty
4. old logfile name must be empty
5. maximum size of logfile must be 0
6 delete the files : \windows\GPSLogFile.txt and \windows\GPSLogFileBack.txt
Under: HKLM\SYSTEM\CurrentControlSet\GPS Intermediate Driver\
- Drivers\GpsOneDevice\PollInterval -> 100 (default is 1000)
- Drivers\InputBufferSize -> 256 (EDITED!!) (default is 4096)
- Drivers\OutputBufferSize -> 256 (EDITED!!) (default is 4096)
- Drivers\SleepOnNoData -> 100 (default is 1000)
- Multiplexer\MaxBufferSize -> 256 (EDITED!!) (by default not present, you have to create it)
AND: from
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver] leave blank the followings (delete the data from inside):
"CurrentLogFile"=" "
"OldLogFile"=" "
With these settings, I have a really cool reception!!
One more thing: if you feel that the reception going worse, do the battery-taking-quickgps-using trick again!
FOR ALL THESE INFOS THANKS FOR THE DIFFERENT MEMBERS OF THIS FORUM!!!!!
(ps: some series ((series "2" ?!)) have no any gps reception problem. If you have this series, be happy, and don't do anything...)
ps2: I've tried other methods also from the forum (for example Nadavi HTC GPS tool, etc.), and made hard reset on my phone many many times to try other methods, but the mix of these methods seems to work, the other ones are not really necessary. So this mix has no contains all the possible solutions from the forum, and this was not the way of selection without thinking..

as I know quickgps and agps are quite different
-quickgps is downloading the latest sat positions to get faster fix
-agps is using phone cell informations also for positioning, besides the satellites
you NEED quickGPS, DO NOT USE aGPS!!!
I've seen lots of people complaining about poor GPS performance - slow to lock, not finding many sats, lag, etc.
But I can't get anything at all from my Touch Pro. I've tried several radio roms, no difference, tweaking the registry settings, and programs called GPSID Settings, GPS Test, and HTC GPS Tool, all without any success.
I believe I should be able to use the HTC GPS Tool to debug, and see the actually serial output of the onboard GPS? But I can't even do that, whatever serial port I try to open I get the message "Failed to send NMEA command...". This suggests to me that the onboard GPS is not giving any response at all, rather than not being able to lock?
Can anyone confirm 100% what com port and baud I should be able to find the on board GPS with? Is there anything else I can try?
BTW, my external B/T GPS works fine with my touch pro, but it would be nice to have the onboard GPS working too.
TP GPS always uses COM4 and any baud (I've tried 4800 to 115200).
Your post is not a "thread" yet and I doubt it will be.
Just search the other threads.
a bit dettered when reading all these GPS problems. Once I've got mine I've had no problem at al besides it showing me a bit off the road in Google Maps. as far as for settings its always been the same COM4 Baud 4800

The default com port is 4. Usually most GPS application should be able to detect it automatically.

Sorry, I thought I did start a new thread, and I have searched - that's how I know about other people's GPS issues. But I haven't seen anyone else with the same problem as me yet.
I get nothing on COM4 at any baud rate.
TomTom says 'NO GPS Device'
HTC GPS Tool says "Failed to send NMEA command..." on COM4 (at all baud rates).
Google maps - when set to "Managed by Windows" just says Searching(0) and gives up after about 5 minutes.
When Google Maps is manually set to COM4 it says "Initialising.." in the top right corner then hangs, and then refuses to reload until I do a soft reset.
Is this what's supposed to happen?
No it's not.
You could have a hardware problem.
I had that issue after uninstalling google navigator 4 trial.Hard reset helped.
Also check Start > Settings > System > External GPS and make sure the Program Port is set to COM4, Hardware should be Port None and Baud at 4800 and Access tab should be checked to Manage GPS Automatically.
I have the "dreaded GPS lag" issue. I don't have this issue but I have found that my GPS is best with the Blackstone Radio 1.10.25.25. I still have to wait sometimes upwards of 3 minutes for a lock sometimes when the sky is cloudy but it seems to work pretty well.
I suggest you try the following
1. Flash to the radio I mentioned above.
2. Go to Start/Settings/System/AGPS Settings
On the General tab, uncheck "Enable AGPS
On the privacy tab, select the following options:
1. Enable AGPS location information to network services. Operator can get your location information.
2. When send location info. to network services: Send postion info directly
3. Close confirmation message after: 10 second
3. Go to Start/Settings/System/External GPS and make the following changes:
On Programs tab: set GPS program port to: COM4
On Hardware tab: set GPS hardware port to: (None)
On Hardware tab: set Baud rate to: 4800
On access tab: check: Manage GPS Automatically (recommended)

A lot of people have problems with the TouchPro GPS especially for pedestrian use...
From stock the TP GPS is quite unsable in car especially with TomTom 7 and totally unusable for pedestrian use.
After 2 weeks of reading and testing tweaks, here are the results of my tests and the applied tweaks to enhance the GPS performance
A. With Advanced config 3.2 http://www.touchxperience.com/fr/ou...ads/9-advanced-configuration-tool-32-cab.html
1. disable A-GPS
2. disable GPS logging
3. logfile name must be empty
4. old logfile name must be empty
5. maximum size of logfile must be 0
6 delete the files : \windows\GPSLogFile.txt and \windows\GPSLogFileBack.txt
7. it seems that if TomTom is installed on a fast microSD decrease the lag(have to test to be sure)
With those changes car usage will be quite perfect
B. Then edit registry with TotalCommander http://ghisler.fileburst.com/ce/tcmdpocketarm.cab
Under: HKLM\SYSTEM\CurrentControlSet\GPS Intermediate Driver\
- Drivers\GpsOneDevice\PollInterval -> 100 (default is 1000)
- Drivers\InputBufferSize -> 512 (default is 4096)
- Drivers\OutputBufferSize -> 512 (default is 4096)
- Drivers\SleepOnNoData -> 100 (default is 1000)
- Multiplexer\MaxBufferSize -> 512 (by default not present, you have to create it)
Tests to be done with buffers at 256...seems to be a little better
Tests to be done with other PollInterval value...seems to "drain" battery
With those tweaks pedestrian usage will be much better but not perfect...I explain.
You have to walk for a least 250m in order to have a reposition with mouvement on the map (before that, speed is always 0km/h) and then if you continue to walk there is quite no lag...and the speed reflect reality
...BUT if you stops you have to walk again for a least 250m in order to have a reposition with mouvement on the map and then if you continue to walk there is quite no lag...
Very strange indeed...
I hope this will help people...please test and feedback.
PS : tests were done with
TomTom_Navigator_7.450.9028_R3_VGA_black_edition
GoogleMaps 2.2.0.16 -- http://www.google.be/gmm/GoogleMaps.CAB
GPSTuner 5.4 -- http://www.gpstuner.com/download/GPSTuner_v5.CAB

If that doesn't help you get a better, if not good, lock with your Touch PRO then you have to have some kinda of hardware problem.
I have an HTC Fuze from USA AT&T activated on T-Mobile USA and I don't even have access to T-Mobile's AGPS Servers and my GPS locks are usually relatively quick.
Good luck!

Rechecked all my settings, but they were all already as above. Still no joy. Only other possibility is that it's being crippled by the ROM I'm using - stock 1.90.206.4 WWE O2 UK variant, although no one else seems to be having the same problem. I am trying to avoid reflashing the main ROM, as it would take hours to get all my programs and settings back to how I want them. Maybe when the 2.0 firmware is released...
I guess it could be a hardware fault, but it seems a bit of a long shot. I really don't fancy my chances of trying to convince o2 that it's a hardware fault.
Try this...
1. Install and configure SecondToday to the left soft-key
2. Install HTC Home Plugin for VGA
3. Install GPSToday plugin and configure it to 5 minute manual-on
4. Go to Start/Settings/Personal/Today and disable all but TouchFlo 3D
5. On your new SecondToday, enable HTC Home and GPSToday
6. On HTC Home's Programs Tab, add your favorite GPS program(TomTom, Garmin, Google Maps, Etc...)
7. Start GPSToday by clicking on the little red box on the far left. It may take about 2 minutes on the first try(it's this way after every soft-reset) but after that it should be much faster. As soon as you are locked on to 4 or more satelites start your favorite GPS program that you added to the programs tab of HTC home.
If it works like it did for me, you should be set. I now get GPS locks in less than 10 seconds every "second time" since it takes about 2 mins after each soft-reset.

Thanks for that. I've given it a try and it doesn't get a lock or even see a single satellite for me. I assume the number in the green box that appears next to the satellite symbol is the number of satellites it can see? It never changes from 0 anyway.
I've never seen a single satellite with the onboard GPS, nevermind gotten a position locked. Beginning to think it's a hardware fault, or my phone got missed when they were putting the GPS in! Convincing O2 that there's a fault will be one thing, then I'll have to flash it back to stock, including the stock bootloader before I send it in.

That's why I put a string of dots on the end ot it...
Don't you think it's imminent, why would they release it for diamond and not touch pro?
I had the same problem for about 2 months, could never get a signal. It was solved when I changed ROM's. I actually tried like 7 ROM's and GPS didn't work in 6 of them. Once I tried RSW's ROM with updated GPS Drivers,,, I am able to always get a GPS signal now.
I do use 2 programs though.
1. QuickGPS to download GPS data.
2. Chartcross GPS Test to open my GPS Port.
Then I open up any GPS program and they all work. (Google Maps, Live Search, iGuidance)
COM Port should be COM4 obviously. When I've used a few GPS programs that "scanned" my phone, they all set the baud rate to 9600. You can't change the baud rate in Settings, but if you have to manually set your baud rate in your program, set it to 9600.
GPS reception significantly affected by case.
Just a FYI. I was a Fuze owner with significant problems with GPS. Could not get it to connect to anything for anything with anything. After trying everything I found on the forum I followed the instructions on this thread ... http://forum.xda-developers.com/showthread.php?t=473481&highlight=lock. and got a lock in under ten minutes. Put my phone back in the case and could no longer get a lock. It then dawned on me that my aluminum case was interfering with the gps chip. Did a bunch of tests which confirmed the reception improved drastically outside the case. It doesn't seem to influence the radio reception however which I find a bit strange. Anyway. My gps works reasonably well and I think people will benefit from knowing something as simple as the choice of case could have something to do with their gps reception.
Ok, There are a lot of posts and information regarding the GPS issue that some are experiencing. I am starting (yet) another post in the interest of compiling and maintaining information regarding that information in one location. As users/devs find out information I will update this post so everyone doesn't have to go looking everywhere for the information. I am hoping that the Moderator will sticky this post.
Some users are experiencing very long lock times for their GPS. Everyone, after reading A LOT of posts/threads it seems to be the consensus that this is a software/settings issue - NOT, a hardware issue. However, results from tweaking the following settings are very mixed. Most seem to get great results by tweaking the following settings while stationary - but, moving is a whole different ball game. I use the below settings and have great results while stationary. However, my G1 blows the Captivate completely out of the water!!! My G1 gave 3-10m accuracy while driving. This device can barely keep me on the correct highway and always seem lagging behind my current location. The G1 was spot on no matter what. What hasn't been determined is if these issues are hardware or software. For whatever my opinion is worth - I think it is a firmware/software issue. Here are some things to try.
Here is the info:
To get to your GPS settings open you dialer and dial the following number. This will not call anyone - it is a code shortcut to the settings:
*#*#1472365#*#*
Once entered you will observe a screen that has five buttons:
Get Position Test
Application Settings
SUPL/CP Settings
Test Application
Delete GPS Data
We will be interested in three of these initial buttons.
Get Position Test: This will be what one uses to test the results of your changes.
Application Settings: Exactly what it says.
SUPL/CP Settings: settings that determine specific data connectivity with the satellites.
In Application Settings the following are some that you might consider adjusting:
Operation Mode - Standalone, MS Based, MS assisted, Network Provider
Accuracy - defaults to 50. Don't set it below 10 (and only use increments of 10's)
SkyHook - not sure what it does. But, someone on a thread mentioned it and it DOES effect satellite lock times.
In SUPL/CP Settings one we'll be interested in the following:
Server FQDN Type
Server
Server Port
The following are the options provided on other threads:
Original/Stock Settings:
SUPL/CP Settings/SErver FQDN Type/Custom Config
Application settings/Operation Mode/Standalone
SUPL/CP Settings/Server/www.spirent-lcs.com
SUPL/CP Settings/Port/7275
Second suggested setup (from other posts and claimed to have great results):
SUPL/CP Settings/SErver FQDN Type/Custom Config
Application settings/Operation Mode/MS Based
SUPL/CP Settings/Server/supl.google.com
SUPL/CP Settings/Port/7276
Other settings that I have played with:
Application settings/SkyHook/On (and Off)
SUPL/CP Settings/SErver FQDN Type/Auto Config (and Custom Config)
You can play around with these to see what gives you the best results. If your GPS doesn't work better with whatever changes you made - than you can always put it back to the orginal settings above.
However, it has been recommended and I concur (for whatever that is worth) that you NEED TO SET THE FOLLOWING BEFORE YOU START PLAYING AROUND: Settings/Location and security/uncheck (turn off) "Use Wireless Networks). Most likely this won't really effect anything while your testing within the GPS settings - however, this will effect your results if you test using Google Maps, etc.
Now, having duly noted all of the above and having played around with the settings for several hours I found the best results FOR MY DEVICE IN MY AREA AT ONE LOCATION was the following:
Note: I adjusted these settings from earlier as the earlier settings proved to be very accurate when stationary - but, very inaccurate while moving. The latest settings I'm using are below. Also, look to the bottom of this post regarding changing your gps configuration file. That also helped A LOT. The bottom section of information is from the Official websites that run the time servers(effects GPS performance).
Application Settings/Operation Mode/MS Based
Application Settings/Operation Mode/SkyHook/ON (VERY IMPORTANT)
SUPL/CP Settings/Server FQDN Type/Custom Config
SUPL/CP Settings/Server/supl.google.com
SUPL/CP Settings/Server Port/7276
SUPL/CP Settings/SUPL Secure Socket/Off
Turning "SkyHook" ON assisted in faster locks with ALL of my tested settings when stationary!
My test results with the above would lock on up to three satellites in under four seconds and between 7 and 10 by eight seconds. Google Maps would locate me in about 6-8 seconds.
Using "Get Position Test" the settings in the three lines above consistently gave the not only the fastest locks and the most locks - but, also STRONGER SIGNALS!
I used at least seven different combinations of the above settings and some of them were just as quick - but, not as strong. Most of them were slower.
If anyone has better information to add then please PM me and I will add it to this top post.
LASTLY, I will make some guesses as to what some of the other settings do as I have heard different information:
Application Settings:
Session Type: Tracking or Singleshot - obvious (use Tracking)
Start Mode: Hot or Cold Start - someone posted on a thread that Hot uses data from your last read to get started. Cold start will start all over. So, Cold start SHOULD increase the time for you to get a lock unless you went left the area to an area that had different satellite to look up.
Test Application:
Performance Test: worked for me - but, I found the test above to work faster and give me quicker results for what I wanted.
Hardware Test/Sensitivity Test: Pretty cool - went on forever and I stopped it.
CNO Test: Seemed to test the average satellite signal strength.
Antenna Test: Never worked for me and I received errors.
H/W Test Settings: Settings for the above tests - I didn't mess with them.
NOTE: WANT TO SEE HOW ACCURATE YOUR ACCELEROMETER/COMPASS/ORIENTATION settings are? Check this out:
Test Application/Show Sensor Data - there is no way to calibrate it here... But, you can see just how sensitive your instruments are!!
Delete GPS Data - I didn't select this button and I don't recommend anyone else doing so either unless someone from Samsung tells us what it does. LOL!
FINALLY: Keep in mind that if you are seeing GPS lock times that are in the 3-8 second range (which was what I was getting) this WILL NOT be how long it takes for Google Maps to get the GPS data! Expect 8-15 seconds or a little longer (but, under 30 seconds) for Google Maps to pick up your location. Although the GPS sensors might pick up the satellites - you still have to give the software time to evaluate the data and apply it to the software.
Hope this helps someone out there.
Update/Additional Information (http://androidforums.com/1194187-post197.html):
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. This is the quickest re-acquisition of a GPS lock.
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. This re-acquisition of a GPS lock takes the longest.
Thanks to Shadow77895 for the link to this info. I altered the settings above. Doesn't effect my results much at all.
MSBased Operation Mode(http://www.vzwdevelopers.com/aims/public/menu/lbs/LBSFAQ.jsp#GenQues11):
What is MS-Based mode of operation?
In MS-Based mode, the network provides the satellite information to the device, based on a rough estimate of where the device is located, and the device acquires the GPS signals from the satellites and calculates its location. After the initial fix, the device operates like an autonomous GPS receiver, until the satellite information must be refreshed, at which time the device goes back to the network to update the satellite information. MS-Based mode is appropriate for applications that require the device location to be updated rapidly, such as a navigation application.

As pool.ntp.org will assign you timeservers from all over the world, time quality will not be ideal. You get a bit better result if you use the continental zones (For example europe, north-america, oceania or asia.pool.ntp.org), and even better time if you use the country zone (like ch.pool.ntp.org in Switzerland) - for all these zones, you can again use the 0, 1 or 2 prefixes, like 0.ch.pool.ntp.org. Note, however, that the country zone might not exist for your country, or might contain only one or two timeservers. If you know timeservers that are really close to you (measured by network distance, with traceroute or ping), time probably will be even better.

REQUEST FOR ADDITIONAL INFORMATION:
Many are suggesting that we do NOT leave the Secure Socket ON. How will this effect data security with our devices? I don't understand how it could hurt us... But, there must be a reason for it. If someone could let me know I would appreciate it.
Good, guide, think you meant hot start should be faster though.
I'll be linking to this.

Great, but doesn't address the problem
I need to point out that while this information is helpful it doesn't really address the problem that the GPS is facing.
What the above settings are doing is enabling multiple different A-GPS technologies to help compensate for the Galaxy S's poor GPS performance. A properly functioning GPS unit would not need these crutches except to acquire a faster fix.
I had my GPS outdoors today, with the first set of recommended settings, and was unable to achieve a fix while seven satellites were in view (according to it) with sufficient signal strength. This is a GPS firmware issue!
The above post is very helpful for people to get some better performance - however - the core GPS issues need to be addressed by Samsung.
I hope people will refrain from saying "It's perfect now!" and let up on Samsung. Unless you know what what the following are you're tweaking settings blindly and declaring victory: ephemeris, PDOP, SBAS, WGS-84, 2D fix, 3D fix (And the conditions one is chosen over the other.) and finally SA
I'm betting this phone would never achieve a fix in an SA environment! It's also clear that the person(s) who originated this information knew exactly what they were doing..!
If anyone is interested in learning how GPS works there are tons of great resources on the web that Google will point you to. Of course they're written for all sorts of different levels.
In short, the above settings may help, but please don't become convinced that things are "fixed"!
I'd suggest you read my posts on the subject:

@haydonxda - I agree that this does NOT address the potential problem that the firmware and/or hardware is inadequate! And, we should put pressure on Samsung to fix this issue. However, the phones have already been produced and I'm just trying to do the best with I have.
@Shadow77895 - thanks for the info. Added a bunch of further information after looking into your posts and references from them.
Try this fix (from 4pda.ru), working on Galaxy S, root access required:
$su
#cat /data/gps/secgps.conf > /sdcard/secgps.conf
#rm /data/gps/secgps.conf
#reboot
After reboot, new (correct) secgps.conf appears.

How do you use the text editor in Root Explorer. I can see the text but it won't allow me to edit it.
Hello, the code:
*#*#1472365#*#*
starts a GPS Test Application.
The settings inside this application are only for this application.
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...
So when I walk outside my office there are like 7 satellites, and I still cannot get a lock. This is sad.
Out of the box it worked great, navigated from BB to my house with relative ease. Inside my house when I showed my parents it worked great. I rooted and deleted some ATT apps. I have yet to get a lock.
I have also changed the NTP servers and no dice. This is pretty saddening performance.
I still don't get why my Nexus One, sitting right next to my Samsung Captivate, is able to get a aGPS location (via My Location in maps) that is pretty damn accurate despite not having a GPS lock and my Captivate is unable to even get an aGPS location and just says my location data is temporarily unavailable.
Nexus One: Can get approximate location very easily
Samsung Captivate: Cannot even get approximate location using WIFI/Cell Towers.
Foursquare never knows where I am until I go outside in the middle of a parking lot. This is BS.
Won't anyone try GPS NMEA MONITOR App and see if the data sentences are correct? If the GPS chipset is putting out the correct Lat/Lon, then you can fiddle and fiddle what Captivate does with the information
Has anyone tried to contact Samsung about the issue yet? I tried yesterday and was on hold for an hour and half and then my call dropped. I'm joint to try again today.
SkyHook isn't a "feature" persay, it's a corporation: http://www.skyhookwireless.com/
Same one Apple uses. Not sure exactly how it works but they do wardrive and use WiFi and triangulation to pick up your position as well, so leaving that OFF will perhaps be better for calibrating your GPS settings, but you certainly want it back ON when in normal use.

What kind of aGPS does the Nexus One use? I tried to dial the code and it didn't bring up the same menu on the Nexus (it may be different). My Nexus is great at figuring out where I am without a GPS signal.
I changed all my settings last night and it seemed to fix the issue. I was getting a lock within 10 seconds or less. Now I cannot get a lock with the exact same settings and reboot. Has anyone contacted Samsung over this? Anyone get an answer from them? I love this phone but the GPS issue sucks.
Every time I try one of these new fixes it seems to work but then when I go somewher else it is broken again they need to fix this asap. I use that feature a lot

Don't give up hope, i'm sure that guy doesnt know anything. Engadget and a few sites are aware of the issue and i'm sure Samsung took notice. i'm sure a firmware fix is in the works.
Location
I have tried all the settings. And I don't really notice any difference. I live in the heart of Manhattan, NY., so I am sure roaming around int he concrete jungle trying to get a lock surely has a lot to do with my GPS issue. I do however, get a lock in every setting that has been written up in this forum, and other forums. The difference to me is hardly any, since it always takes many minutes for me to get a lock. I never have used any other GPS device since living here in the city, so I would like to ask other who live in a large city if it is taking them several minutes as well? Because it seems as though people are saying it is taking them only seconds to lock on. Hmmm.....
These settings work the best for me so far. I live in new york and i get a lock in 5 seconds flat!
1. Navigate to Settings > Location & Security and uncheck the box next to "Use Wireless Networks".
2. Go to the phone's dialer and enter the number *#*#1472365#*#* then press send to access the phones LBSTestMode menu.
3. In the LBSTestMode menu, press “Application Settings” and change “Operation Mode” to “MS Assisted.” & turn "ON" skyhook
4. Navigate to the “SUP/LCP Settings” and the change the SERVER & PORT to supl.google.com and port 7262
5. Make sure the settings are saved and reboot your phone.
6. Navigate back to Settings > Location & Security and check the box next to “Use Wireless Networks.”
Tried it. So, question: Should I leave the Wireless networks on generally? For things like geotagging pictures, weather updates, etc, and then turn on GPS Satellites in the event I want to use navigation? In that case should I turn off Use Wireless Networks or just leave it on? Any ideas on those things?
I'm in a basement apartment, so GPS testing and such is pretty much a moot point in here, but I do want to mention that I made the changes you suggested, rebooted my phone and went to maps and it picked me up on there instantly. This is without GPS satellites checked and using the wireless networks. This seems to be already a huge improvement because yesterday I was standing outside for 10 minutes with 8-9 satellites in view and google maps couldn't find my location.
awsome... glad it helped... i keep Wireless networks on and i get a lock in 5 seconds flat... try it both ways and see what works for you... but these are by far the fastest and the best settings...
I live in West Tennessee, I tried these settings about 15 minutes ago and I have yet to get a lock.
I tried this and it worked. I generally don't have my WIFI on, so i turned it on and went outside. had a lock within 5 seconds (i was connected to my home wifi).
u guys the use wireless networks uses things like wifi and ur wireless provider so ofcourse it be faster
STOP telling people to use MS assisted. That only helps while standing still. For moving it is worthless. Use MS based instead.
there's already a thread for this....
i didnt know about ms assisted/based, do you have a link with more info on that?
if that is true... then when ur in LBStestmode... and you are doing a get position test... why does it show my speed? i have tried it in my car and also while walking... gives accurate speed
Speed on the menu isnt a very good measure. Use a GPS app and get in a car and you will see it keeps losing track of you (jumping all over the place or losing fix)
Here is info from verizon:
http://www.vzwdevelopers.com/aims/public/menu/lbs/LBSFAQ.jsp#GenQues10
There is a sticky already and this thread is redundant.
This is a placebo fix. It doesn't do anything. Stop making threads about this people. There are already plenty and it doesn't work.

I agree. I didn't have any issues to begin with but I applied this "fix" just to see if it would make a difference and my GPS went to CRAP! I restored default settings and am back to getting a fix in about 20 seconds.
I'm aware of the GPS issues with the Samsung Galaxy S. I have the Samsung Galaxy S 4G and I'm wondering if anyone with this phone is experiencing difficulties getting GPS to lock in.
Within approximately 10 minutes, I can see in the GPS Test app about 3 satellites in view. Given enough time, it picks up a few more and eventually locks in.
I've read about the Super GPS fix and the hardware fix but I'm not sure if it would be wise to try it on this phone since the fix was meant for a different model and I don't see any mention of anyone trying it on the GS4G:

Locks quickly for me without any "special" settings or apps. I even have network-based location always off on my phone since I don't want Google tracking me all the time.
The first lock may be causing you problems if the orbital data hasn't been loaded recently enough.
I have read that GPS Status has helped some by causing the orbital data to be refreshed.

I have a Samsung Galaxy S 4G and a Vibrant, both are horrible with GPS, they both take forever to get a lock and many times they never get a lock and Samsung is less than helpful. They had my Vibrant for three weeks and sent it back with nothing changed.
mine has never taken more than ~30 seconds to get a lock, even if that 30 seconds sometimes feels like "forever".
this is my first GPS-equipped phone, so i don't have anything to compare it to, but once it's locked, subsequent locks take less time. maybe i just got a "good one"?
I have a Vibrant and an sgs4g. There is no comparison between the two. The sgs4g takes about 5 seconds to lock, The Vibrant I've waited literally 40 mins and still never got a lock. It could be the app. Are you having any trouble with google navigation taking along time or just the gps test app?
I know this wasn't directed at me, but I share the same GPS problems.
This issue occurs in all GPS Apps, including Google Navigation. It simply says acquiring GPS....
The GPS icon flashes like it's working, but its not doing anything.

Looking in the market there's an app called GPS Aids V2...anyone try it? Supposed to help all Galaxy S phones with GPS problems.
Before buying, I want to see if it's worth it......
__________________________________________________________________________________________________________________
Just kidding, I bought the app. So far it seems to be working well; after doing everything my phone was actually picking up FIVE satellites.
Not working right now, though. I contacted the developer for some help, and I'll post his reply/an update soon.

-Download LauncherPro first.
-Tap and hold on your homescreen, and select shortcut.
-Click Activities.
-Scroll to LbsTestMode.
-Tap the first one, LbsTestMode (with gray saying com.sec.android.app.lbstestmode.LbsTestMode
-Click okay when "edit shortcut" comes up.
-Open the shortcut.
-Tap "SUPL/CP Settings"
-Change the following fields to...
Server -> supl.google.com
Server Port -> 7276
SUPL Secure Socket -> OFF
AGPS Mode -> SUPL
-Click Back (it saves it)
-Reboot your Phone.
-Click Settings, then Location & Security.
-Check "Use Wireless Networks"
-Go to your Launcher, and open LbsTestMode again
-Click "Delete GPS" Data
-Exit the App, and close it with a task killer.
-Open it again, and click "Get Position Test"
-It might take a while for something to show up....but it eventually will. Let it run for about ten minutes straight.
-Close the App again, and you should be good!
Upon Position test....I got:
Accuracy: 41 (meters)
Number of Satellites (INDOORS!): 9
Speed: (m/s)
If you have any questions feel free to reply.
Remember, credit goes to "Bade" (which credited XDA forums anywho) of samsunggalaxyforum.com
Running Copilot Live (GPS Application) and finding location took less than 5 seconds indoors.
To check some info out, I ran GPS Test, and saw "In View" Satellites was 9, and "In Use" was 7. (both were 2, to 0 respectively...previously.)
Running GPS Test (another app, different) came up with my location in less than a second.
I'd call this a success

My GPS was working but I wanted to mess around and check on your findings. I tried to get this to work but it took quite long looking for Satellites.
I noticed when I went in to modify the SUPL settings, it was set to custom config. Made the changes according to your post and like i said before, it took a while so I stopped it. changed the settings to auto conifg and BAM! pulled 13 satellites and locked in within seconds. I do not know if its due to my location but Im working great on Auto Config.
this post is more of an FYI rather than a fix. Hope you guys get yours fixed either way.

On the first try, you have to let "Get Position Test" run for around 10 minutes (The 3 minutes on the original post I said might've been a stretch).
Trying Auto Config, I'm getting similar results, though with the custom settings I had more satellite lock-ons.
Custom:
12 SAT, 10 CONNECT
Automatic:
11 SAT, 7 CONNECT
After doing this, the GPS data should stay downloaded on the phone so future satellite searches are MUCH quicker.
Thank you for your input by the way..I appreciate it
My phone has always find satellites and locked within 30 secs. One day I started messing around with settings and came to find out my gps was no longer locking on any satellites at least for 10 mins. I bought the gps aids v2 app from the market then tapped on gps doctor and tapped on "regenerate" (it regenerates the gps data folder) it made my phone boot up. Since then my gps has been workin excellent after that.

I tried the same thing, except with that app I couldn't download the XTRA data once resetting the settings :/
Me neither, it couldn't seem to download the xtra data, but just by tapping on gps doctor and "regenerate" and in my case that fixed it. Good luck!

I have the gs4g and tried GPS AIDs with some improvement . At the most I would lock onto 7 satellites when it felt like working. I lifted the contact as indicated in the thread above. I then deleted the old GPS data. Then in GPS AID I regenerated the DATA and rebooted. Now i get 12 locks on satellites all with green signal status. Very please. Google maps Locks on with in seconds....

I think I spoke too soon. I tried this in Calgary and it was great. I'm now in Toronto and I haven't gotten a lock since I got here on Monday. Tried messing around with the settings again, but just won't lock on. Also tried auto config to grab SUPL info from my provider, but that didn't work either. Still working on it.
Start over and flash krylon deoxed with odin, cwm, bionix. This resolved my 10-15m lock times completely. Now I get a lock in seconds.

Amazing!
I tried this and got accuracy within 3 meters off 10 satellites. Before, it was about 80 meters. Just awesome.
You don't need launcher pro to get into LbsTestMode. In your phone's dialer, just type *#*#3214789650*#*# and it'll go into it.
As for what you suggested about going in and messing with the settings, the first lock takes forever because you've wiped out all the ephemeris data by deleting. It starts looking for satellites for your first lock which takes a while with no ephemeris data. Once it gets a lock, it starts downloading ephemeris data and subsequent locks are significantly faster because your phone now knows where the satellites are.
AGPS helps reduce the lock time a bit (by using mobile location and the SUPL server), but not by a huge amount. The largest reduction in time is due to the fact that you have updated ephemeris data. If your ephemeris data is outdated, your lock times will go up again.
If you don't believe me, try this: get your lock. Then shut off your GPS by using the pull down panel. Leave it off for at least 24-36 hours. Then try to get a lock again. It's going to take a long time again...
I've been tinkering with the GPS on this phone for a while now as well as my GF's Vibrant. There's no doubt in my mind that the SGS4G is improved over the Vibrant, but it's still not great.
I've also pulled apart both of these phones and done the hardware fix by bending the little tab every so slightly. Made a significant difference on the Vibrant which was having a problem maintaining locks and the GPS signal was bouncing all over. No noticeable difference on my phone.
My only conclusion is that the antenna on these things are poorly designed and just take a long time to get an initial lock. Once locked, it's pretty solid. Other phone manufacturers have GPS that work better though. No reason why Samsung couldn't do better.
