Hi all. Got my att g3 the other night, was playing around with it and everything was working fine. Then I rooted using stump root, now my GPS has issues getting a quick lock. Could that have broken the GPS? I did a factory reset and no improving. I tried various GPS fix apps from the market also with no luck. GPS test app says it sees around 20 satellites with 8or 9 in use but no accurate lock. Any ideas of what else I could try?
No one has any ideas? I don't think it's a hardware problem, because sometime I get a lock in a couple seconds, other times it takes 5-10 minutes. Once I get a lock, it's rock solid, very accurate and stable.
Are there some files someone with a working GPS can give me and I can replace mine?

Hi Guys,
I've been hearing about lots of problems with the GPS not picking up low SNR satellites and the GPS being wildly inaccurate on the samsung vibrant and also the euro variants of the galaxy s.
Does the captivate have the same issue?
Its true. I bought it on sunday an notice that issue. Hope there will be a update(Bug fix) soon.
Compare to my G1, the Captivate take about the same time to lock and GPStest says the SNR is better. I'm happy with it.

Define Wildly inaccurate. On my Captivate it is dead on (within 9 feet)
I am having major problems with GPS. I am getting a lock but only within 50-75 feet. It isn't good at all. The GPS is slow to update and throws me everywhere.
I amthinking of returning the phone if Samsung doesn't make an announcement about s fix for this.
dial this from your phone:
*#*#1472365#*#*
Change startup from hot to cold.....worked for me. GPS locks much much faster
What are the settings on your phone Citznfish? My phone is off by anywhere from 100-500ft. Thanks!
Ok, I tried it again... In the house I'm about 500 ft off from where I really am and placed in a golf fairway. Outside I am FURTHER off: I'd estimate at least 5 blocks and placed in the middle of a different golf fairway. For comparision sake, my wife's iPhone 3Gs has her within 10-20' while inside the house. To me, this is unacceptable and a great cause for concern. What can I do???

I'm having the same problem here. My iPhone 3GS GPS responded way quicker then this phone does. I have a Weather Channel widget up, and it doesn't find the location to display the weather for a good minute and a half after. Same goes for using Google Maps to find my location. Lot of times it says, "Your location is unavailable." I even tried switching the startup from hot to cold, and that didn't have much effect either.
When I was driving today, the GPS locator had a bad lag in it, I would be down two blocks before it would catch up, and I live in a 3G area, and not a giant city like NY or something.
I wonder if it's because it's so bloated with Samsung UI on it, or if it's just the a bug. Either way, if I'm still having issues with it, I'll see if AT&T will exchange it out for a different one. Otherwise back to the 3GS, which I really don't want to do since I'm loving Android right now.
What does hot start and cold start do?

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.
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.
Danm a cold start sounds like it would be slower. I tried it and I still can't get a lock within a reasonable range.

I've been reading online that the Galaxy S got a firmware update that greatly improved/fixed the GPS problems we are experiencing. I can only assume that we will have to wait as well for this firmware to completely fix the gps issue.
Try the fix/workaround in the Vibrant forum.

I went from seeing 1 satellite and none locked to 7-10 seen and 5-7 locked.

Where did you read this? I've been looking for something like this, preferably from Samsung.
i havent had too many problems with GPS here
Google maps usually locks me in a few seconds
Third party applications can take much longer, however
The problem might be the way the third party apps utilize the GPS

Actually that isn't a fix at all. It makes locking onto satellites much faster, but nothing to address the sensitivity issues, and there is definitely an issue. I 'found' 9 satellites, but could only lock onto two of them, for a few seconds at a time, then back to zero, out in the open.
Hopefully a software fix is on the way.

This fix did help me so now i get a quick lock...as ling as i dint start moving around. It stays close enough to exact to use for driving around but not more accurate than that. The problem isn't really getting a lock so much as keeping it.

Well, I change my mind. While what I said still stands, I've since found that the GPS and the Compass don't track very well. I tried find a geocache using the same GeOrg software I use on my G1. The location seemed to be stuck as I was walking. From my experience with the Tilt, I'd say the GPS is running in "Static Navigation"
The clock is ticking, GPS has to be fixed in 28 days, or the phone gets returned.

I was having problems w/ GPS on my phone as well. Would be way off in Google Maps, Navigator took forever to lock, and geo-tagging photos was also way off. I did something similar - dialed the code to get to the GPS settings. However, all I did was turn Skyhook to ON and switched configuration from manual to auto. I don't seem to have any problems between yesterday and today. It locks incredibly quick and is very very accurate.
Some of you should try this method and see if it helps with anything. Good luck.
I just got my sensation yesterday, coming from the G2x, my gps lock when using google maps/navigation takes more than 10 minutes to lock. I turn in in landscape mode loses data connection as well. Anyone else experiencing very slow gps locks? My g2 was instant
Something is wrong. Mine takes about 20-30 sec.
Return it

Same exact thing here except for the data issue, on my second device and its nothing like my G2. Have you Tested other areas? Use gps test (by Chartcross Limited) and see your signal strength and how many satellites you can connect to.
My G2 can see 12 in a few sec
My Sensation only sees 3-0 at poor signal
Don't really have an option to return it cause I purchased it off of craigslist, and I use Simple Mobile. So I don't even have a T-Mobile account. Unless someone knows a work around this, I am forced to send it to HTC for "repair".
Just got my Sensation yesterday. First thing I tested was GPS. My heart sank when it saw zero sats outside. Tried various test apps, Google Maps, etc., checked and double checked settings, rebooted several times. Nothing. The GPS icon never even showed in the notification bar. Was about to box it up to send back and decided to pop the battery out. Rebooted, and bingo! Excellent signal strength even indoors, very quick locks, typically accurate to under 15 ft, and very stable map location. As close to perfect GPS as I had hoped for. Coming from the Vibrant GPS fiasco I'm VERY happy.
wish I could say the same about mine

Did you download GPS test from the market and use the calibration tools? It could help. Or you can also try pulling the battery (old BB trick) instead of restarting to see if that helps. Keep your head up.
I got mine yesterday and had the same experience. I fixed it as follows:
SETTINGS->LOCATION -> Make sure "Use Wireless Networks" is UNCHECKED
Since unchecking that option, my locks are much faster.
However I turned WiFi Calling on and it started behaving like before. Never seeing satellites, minutes for lock.
I turned off WiFi Calling and now I get <10sec lock again.
Sounds like a software issue that HTC needs to figure out.
Let me know if anyone has success with this.
Did you try it out inside?
I just went outside and it's pretty cloudy and got 5locks in 3seconds and 10locks in under 10 seconds.
So there is something wrong or you are doing something wrong
I'm having trouble with my GPS and after searching forum after forum I can't seem to find anyone with the same issue as me, specifically: my GPS not being able to keep the satellites signal.
First off I'm running NexusMod 5.0.4 Beta2 on UCLF6. I've tried both: GPS Fix for Nexus and AGPS Patch. Both work, especially the GPS Fix for the Nexus. I get a lock on satellites quite fast, up to 11 sometimes.
But I am ALWAYS losing satellites. I am constantly going between 5 to 11 satellites and my accuracy is constantly ranging anywhere from 20m to 60m. It's absolutely infuriating looking on GMaps and Navigation and to see that damn blue circle growing larger, smaller, larger, smaller...
Anyway, after two days of searching I'm hoping someone has the same issue as me and hopefully a solution. If not, does anyone have any suggestions as to what in the world could be causing this? I'm hoping it's not a simple solution as the ROM itself since I absolutely love my current ROM; however this was happening when I was running Sky-ICS Themed Gingerbread as well.
Thanks.
Did you ever figure out what was going on?
Were the 5 to 11 satellites seen while inside or in the open?
I am having similar GPS issues and was wondering what the "normal" number of satellites is. Mine seem to range between 0, 2 and 7, and is constantly varying.
At this point I am not sure if in my case it is some sort of hardware issue, or if there is something going on in software.
These symptoms initially showed up while still on stock GB 2.3.5. I made the plunge, wiped everything x3, and tried one of the JB ROMs. GPS seemed to lock on immediately, but would intermittently drop off. I've tried numerous of the GPS fixes out there, but same problem.
I've read elsewhere to wipe even the external SD card, so I am in the process of trying this as a last ditch effort.
If you found any answers or solutions, would very much appreciate what worked for you.
Thanks!
Friend of mine recently told me her GPS on her verizon S3 stopped working. she brought it by, i flashed the newest build of cleanrom on it today and sure enough the GPS still doesnt work. everything needed is turned on but it doesnt get a lock. i checked it with the GPS Status app and it shows like 0/20 satellites and doesnt lock to any. only way i was able to actually get somewhat of a lock on google maps was to hook it up to WiFi and let it gather from that.
any suggestions?
Somewhat common problem. I haven't found a fix as of yet. There is a gps fix somewhere in these forums though that sort of helps. my phone had the same problem. Going back to stock or to any custom rom, nothing worked, the gps was just dead. After flashing one of the fixes I finally managed to get it to get locks, but it needs like 7-8 satellites to get a fix, is highly inaccurate, and loses gps lock a few times on every trip.
Here's the gps fix page
http://forum.xda-developers.com/showthread.php?t=1880411
I use Galaxy s3 test 3 alt, it's the only one that gets any lock for me. The first time and other intermittent times can take up to 10 minutes or more though, and rebooting the phone or trying again another day does sometimes help.
I know it is definitely the phone, as my pantech marauder which has the same SoC which should be very similar for gps location, finds and locks on to 6-8 towers in like 10 seconds or less all the time, even indoors, and gets location accurate to less than 100ft with 4 satellites while the gs3 needs 7-8 satellites to get a lock to 300-600ft
If none of the software fixes work. And the stock unrooted software does not receive GPS lock.
I would highly recommend replacing the GPS antenna just in case.
I'm 90% sure the headphone jack. External speaker. WiFi antenna and GPS antenna are all in one unit.
This piece is sold for cheap on Amazon. Or eBay or whatever.
Replacing is simply a removing a couple screws and popping the old one out.
Here is a link to eBay

Possibly you could find one cheaper.
Hopefully this is it for you.
Let me know how it goes.

I too have this problem: the GPS no longer gets a fix w/o a data connection
the phone recently did an update to jb 411 and now no gps fix w/o data.
I do NOT believe its the antenna.
does anyone else with the os in sight have any info?

I too have the same problems on this rom
So, my unrooted, stock g3 is having GPS issues. Sometimes it will se satellites and lock right away, other times it won't see even one satellite. This is all outdoors. I've tired clearing Agps, restarting, calibrating the compass to no avail. Any one else having these issues? Any solutions or ideas? Thanks.

Any update on this? My G3 is slow in picking up GPS and will constantly drop out every few minutes, taking another minute or two to find GPS again.
