Has anyone else been having issues with there gps? I have it turned on and often times maps will only be like 1000m accurate. Sometimes it gets like 10m accurate, but it can take forever to get a fix. And sometimes it doesn't.

are you rooted? if so, what ROM?
I am rooted, but on the stock ROM still. I have location services on all the time. Could that be messing with it?
do a search...there are threads that offer some "tips" to cure the GPS problem
Two quick things:
I did two quick things, both suggested elsewhere on this board, and now get gps lock within seconds.
First, I disabled the Google location services, but saw no appreciable difference in lock speed.
Second, I downloaded "GPS Status" app. Menu > Tools > Manage A-GPS state > select 'Reset', then follow the menus again and select 'Download'. This resolved the issue for me.
I am also running a custom ROM that changed the GPS setting to US from North America (again, as suggested elsewhere here), but that alone did not fix the problem for me.

+1 Same things fixed it for me....
I fixed mine. It needed to be flashed with a gps file to fix it. I think the file can be found on one of the forums. I'll try to post it tomorrow.

What has helped for me is to change the servers back and forth in the instructions for the GPS fix in the dev section... ie the GPS.conf file... Switch it to the suggested server to fix... Reboot... Test your locks with GPS Test app... If still not working... Switch back to North America server, reboot, and test again. Right now I'm on Virus rom, which comes with the server in the GPS fix... But i was still having lock issues... Switched back to the North America server and rebooted... Now it locks quickly and with 6.6 feet accuracy.

Hi
I did what u say, but my gps still a bit off. But better than before....
thanks
You are welcome... Secondly, if your GPS is still flaky and you're running a 09 rom might want to flash a 06 rom and see if that helps. Best of luck...

This did it for me too. However, you MUST wait for the swirling circle to stop spinning and get a "lock on" which will then show your lat/lons. Be advised this can take several minutes! Be patient.

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.

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.

-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

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.

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 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.
My GPS stopped doing accurate readings when i flash roms with the ziggy gps fix. the only way that it gets accurate(within 20m) is with wifi on and connected, if its off it says accurate within 3700m. Thats not too accurate if i might say, anyone else having this problem/ found a fix for it?

Interesting, I attempted the same thing and I am unable to get a lock when I disable the Google Location Services.
I'm running on Das BAMF 1.3.2 with the kernel update 3a which includes gps fix/enhancement from Ziggy.
I've been testing how quick I get locks when using the Navigation and I am still seeing a considerable amount of time before it finds a GPS signal. I've also used GPS Status from the Market to reset and download GPS data but I haven't really seen a difference.

Used this method and Ziggy's GPS mod and I get a lock within seconds as opposed to 10 minutes. If I turn on Google Services it goes back to a 10 minute lock time so I think it has more to do w/ the Google Services rather than modifying the GPS Config through Root Explorer.
Edit: I will add that initially my phone will say "GPS Location is Currently Unavailable" and 2 seconds later it gets the GPS lock /shrug
Well mine stays searching when the Google location is off, never gets a signal. What is the stock gps server so I can switch it back?

That is odd that WiFi affects the GPS locking. I'm trying to find anything I can on this. "Searching for GPS..." in Navigation is annoying as heck.
I also had a sneaking suspicion that toggling wifi on and off caused gps lock issues, I was using another rom at the time, but for some reason, all of those problems ceased when I flashed TeslaCoil and completed the gps conf fix.
Not withstanding, gps should lock quickly using only stand alone, and right now, my gps works splendidly

You can grab it here:

It edits the gps.conf so the NTP_SERVER=us.pool.ntp.org
That comes default on the roms I use tho. Still attached to WiFi switch. What's the closest lock you can get with your gps?

i was having GPS issues with the last two bamf kernels. google maps seemed to lock onto my location after a few seconds or a minute, but other apps that tried to use the GPS would never lock on. i noticed when you go into google mapls, the GPS icon/animation appears on the status bar.
the GPS icon would never appear for other apps that tried to use GPS when using the bamf kernels.
with the stock TB kernel, all is well.
Ok, gps is definitely tied in to WiFi. Without WiFi on its 3400m away and with it on is within 20-50m. That only happened with the ziggy fix so maybe if anyone could show me the original settings for the stock gps server file I could change back and forth and test what the problem is.

So I rewrote the gps.conf back to the original north-america setting and that fixed the problem. Any clue why ziggys rewrite of a word in that setting would mess it up so much? And how is it ppl are supposedly getting improvements with that, like what exactly?

I don't know what the rhyme or reason would be for this gps issue, because it's so random, there is no pattern to this mess:
1. Got the phone, gps worked great.
2. Rooted phone, still worked great.
3. Flashed first rom, Virus to be exact, still worked great.
4. Several days later, with no rhyme or reason, I noticed that Cardio Trainer had not picked up location
5. Factory reset, problem still persisted, could not lock on to any birds, confirmed with gps test app.
6. Flashed CWR of stock rom post root, still not working.
7. Flashed RUU stock from fastboot, working again perfectly.
8. Have flashed 2 non stock roms since, BAMF 1.3.1 and first TeslaCoil (current) and gps still working perfectly
I can't think of what could have possibly caused this, but now that gps has been stable for about one week and I haven't been using wifi, over the weekend I'm going to toggle between wifi and 3g and see if it causes any issues.

Joanni, I'm having the exact same issue that you've been having. With Google services on, I get the wide area. If I turn it off, I get nothing. The only way I get a lock is with WiFi on. I'm currently running Virus ROM.
I know enough to be dangerous when it comes to digging into my phone. I generally just follow well polished instructions. How would one go about trying your fix?

Joanni just edited the gps.conf file to read NTP_SERVER=north-america.pool.ntp.org
That was the original setting. It has been said that changing the setting to us.pool.ntp.org has fixed peoples GPS locking issues but in my testing I found no benefit either way. What I have found, is that turning WiFi on will enable the GPS to have better accuracy in finding your location (20 meters to 50 meters in my case). This is exactly what the popup says, the first time you launch Google Maps.
If you wanted to check what your gps.conf file has set as the server, you can use Root Explorer and browse to /etc/gps.conf
There is also an app in the Market called FasterFix that will change the server to north-america.pool.ntp.org for you.
The following seemed to have helped some people on my post on AF so figured I'd post it here as well.
If you're still having GPS issues in an area where you have data coverage, and you've tried changing the gps.conf and possibly updating your libraries as noted in other threads, have you tried changing your GPS settings to MS Based instead of the default of "Standalone"?
From wikipedia:
Mobile Station Based (MSB) - In MSB mode A-GPS operation, the A-GPS device receives ephemeris, reference location, reference time and other optional assistance data from the A-GPS server. With the help of the above data, the A-GPS device receives signals from the visible satellites and calculates the position.
You can do that by doing the following, as noted in my previous post:
My GPS was really taking a long time to lock. Usually 10 minutes or so using GPS Status before it would lock. I tried both just using gps only and then also with wireless network and it still took a long time. So I updated the lbstestmode.apk to use MS Based and the gps.conf file that was mentioned earlier and now I get a lock in GPS Status in about 8 seconds from a cold boot using only the GPS with no wireless network.
If anyone wants to try, I've attached a flashable zip. I took the zip posted by merkuralex earlier in the other gps thread (thanks merkuralex) and added the lbstestmode.apk posted in this SDX thread:
http://forum.sdx-developers.com/index.php?topic=13593.0
The following flashable zips are attached:
lbstestmode_mt_gps_conf.zip - contains the gps.conf file from the other thread + the lbstestmode.apk file.
lbstestmode.zip - contains only the lbstestmode.apk
I'll repost the instructions here (thanks to cornaljoe on sdx for the actual instructions):
Pre-1. Flash the one of the attached zips in CWM first to install the lbstestmode.apk (or just copy the lbstestmode.apk into /system/app/ if you'd rather) and then reboot your phone.
Follow these directions:
1. After boot create a shortcut to Activities -> LbsTestMode -> .LbsTestMode
You may have to install LauncherPro if your launcher doesn't support the activities option under shortcuts. Once installed all launchers will have this option.
My note: Just an FYI, LauncherPro can be downloaded from the Market for free if you don't already have it. Or any other app that allows you to create shortcuts (such as AnyCut I think can also do that)
2. Start LbsTestMode and goto the application settings and set it to MS Based and press back until you exit app.
3. Reboot phone and then use GPS Status under a clear sky until you get a lock.
The main thing to pay attention to is the numbers labeled Error(m) and Fix/Sat in the lower corners of the compass.
Error(m) is the accuracy of your location in meters which shows after you get a lock. Fix/Sat is the number of satellites locked and in view prospectively.
In GPS Status, you can do the following to force aGPS data to download:
3A. Click Menu --> Tools --> Manage A-GPS state --> Reset . This will clear all previous A-GPS data.
3B. Click Menu --> Tools --> Manage A-GPS state --> Download. This will download fresh A-GPS data.
3C. Let GPS Status lock. The first time will take longer as your gps/phone syncs the data.
After you get a lock, you can try powering down your phone and then restarting and see if your lock is faster from a cold start.
This may or may not help you. All I can say is that changing to MS Based helped my gps lock time--I usually have data access where I am.
I have done this, and it works perfect!
Cloudy and raining here today. I will definitely try it. Quick question though, you saying use either zip or use one before the other? I'm not really clear on this.
Also do You have to keep the short cut?
You need to apply the zip first (in CWM) or else you won't have the option to create the shortcut
Wich one, there's 2 zips? I've got it all installed and working. Even though its cloudy, I got instant lock on. I'll test it again tommarow when I go out of town. So far so good though.
Edit: indoors is about 10 sec lock on. Great find OP. Has anyone posted this over at hofo? Another question, will clearing data cache from apps hurt it any?

Everything went great today. I left my phone off all night so it could get a solid cold start this morning. Its cloudy and rainy again today too. I hit the road this morning and fired the GPS up and it locked in about 15 seconds. Great job on this fix. Also since then it has been instant lock times when i try it.

Actually I installed them both...lol But that's the last one I used.
I did have a bit of a hiccup on my way home. After lunch I turned my phone off. When I got back on the road 3 hours later I turned it back on and started up Navigation. It took a minute or so on the first lock. I exited out of Navigation and waited 20 minutes or so. I started it up again and it took about 30 seconds. Every time after that it was instant lock. Still very impressed. It was very cloudy and rainy today though. I was getting 1.1 mb down and 500 kb up today also. I would post this over at HoFo for all the nay sayers, but I wouldn't be able to answer any technical questions if anyone had them.
This place is starting to remind me of Seatle, rain every day...lol. I guess Fall is here to stay.
You are wasting your time.
I have traced this code extensively. For those who are unaware the GPS works on RPCs, which are internally processed by the kernel and passed to the chipset.
The chipset on this phone does not know how to handle AGPS requests - XTRA requests to inject the time (NTP time) and the orbital data are flatly refused.
You can set whatever you want, the data will never get to the chip. The Froyo base load intentionally discards such attempts and never sends them. If you load Gingerbread (and build it from source, as I have) and FORCE it to be sent it will return an error every time.
The problem appears to be in the silicon and/or the radio driver itself, which there is no source for. If someone's going to fix this, it's going to be at the radio interface level - not in user space.
My CM7 port is capable of cramming the data in there but it's turned off right now as when I enable it there's a fairly decent chance that the consequence of trying to do so is that the radio locks up and forces a watchdog reset (that is, a reboot on the phone)
Hey guys, i had a question, and forgive me mod's if there is already a thread for this. Let me know and i'll post in there. But i was wondering if anyone else was having this problem. My shift's gps is not working, nor has it since i got it about a month ago. I've tried everything from downloading gps toolbox, to trying to to update the gpsone tab in qpst. Now, when i go to enter in the server ip address in gps, and the other settings, i write them to the phone, try turning on gps toolbox, standing in one place for 5 or so mins, nothing, not one damn satelite. I go back into qpst, and all my settings in gpsone tab are gone. Wtf? Anyone having this same problem?

When you flash a rom, do you first thing connect up to your wifi before you sign in to your google account?

In GPS settings turn on "Use wireless networks". Problem solved.

I figured out GPS for the most part. Please read my earlier post:

2) After spending lots of time on GPS I found that getting the first lock is the most important thing and then it just works.
As of this time my opinion on GPS is that I am still unsure as to whether or not fasterfix changes anything but wireless assistance is definitely needed to get a good first lock and is used by some apps in acquiring location.
If you don't get more than 2 satellites in GPS status and it takes a long time to get those 2 satellites GPS hasn't gotten it's proper first lock yet.
This has nothing to do with having the GPS getting a lock in sense. It seems the GPS needs to use wireless assistance first to get the lock (contact sprint servers or something) and then it works pretty well. Still experimenting to figure out how exactly the GPS works and what the optimal settings are for it.

So yeah, try fasterfix and set to north america NTP Server and then in GPS status hit the menu button -> tools -> reset AGPS data and then menu tools -> download gps assistance data

Haha no problem and good luck! Make sure you keep us updated! GPS has frustrated the heck out of me for the past month. That's the best I can come up with at this point. Need to have wireless assistance on and the first time you boot the phone on any rom you should be outside and get a good lock with a clear view of the sky. After that it's good to go.

So, should I flash my rom again? and avoid setting up google account, then run the apps?

No just go to GPS settings, turn on use wireless networks, use faster fix, then open maps and try and get your location while outside and with a clear view of the sky. The GPS icon will stop flashing in the status bar when it has a lock. It will stay in the status bar as a solid icon, meaning that it is locked.
Then run GPS status and see how many satellites you get. You should get at least 4-5+ (up to 9) when GPS is working properly.

any idea how long it takes to get a lock? i've literally waited 5 to 10 minutes before

No longer than 30 seconds if you have good reception.
Spoke with OP via IRC, he is flashed on Metro PCS. Seems like he isn't flashed properly and also doesn't have MMS working. If anyone has any Metro PCS knowledge please feel free to chime in.
I read a while back that there was something that can help your phone lock on to GPS faster. Recently I have been having issues locking on to GPS without restarting my phone. When I restart it, it picks up GPS right away. But if the phone has been running for a few days it always says "searching for GPS" in Maps. Is there something I can flash to make it lock on quicker? So I dont have to restart my phone when I want to use GPS or Maps/Navigation? It has always done this on whatever ROM I flash.
I don't know if it will help with your situation or not but I use an app called GPS Test. Tons of useful info and such. Also allows updating of agps data. My GPS seems to lock quickly

GPS test didnt do anything. I thought there was something that was posted that you could flash that would make it lock on faster? But I cant find it now. I always have to restart my phone to get driving directions in Navigation. But the thread did have to do with a-gps. i just cant find it...

There's a patch for HTC devices that uses an alternate data source for AGPS data. It *might* work on this phone-- I don't know why it wouldn't. Perhaps that's what you read.
Also, the updated Play store fixed an AGPS lock issue with HTC devices. Again, it appears this is only an HTC fix, but it could be what you came across elsewhere and are referencing above.
I haven't used "GPS Test", but there are two different apps named "GPS Status" in the play market. Both allow for AGPS location data to be refreshed, and produced satisfactory results on my HTC Sensation. They appear to be device agnostic, and would be worth a try. I went from a maximum fix of 4-6 satellites on my Sensation up to 12-15 satellites (under ideal circumstances).
Wifi and bluetooth can also cause occasional fix issues-- make sure both are turned off. I get massive GPS lock problems with Wifi turned on-- not so much with bluetooth.
I know this is a old thread but I thought it would be useful if I would share this. It was a fix for the Hercules but since its like our big brother (lol) I think it should work for our here blaze..
