Very Slow gps lock - HTC Sensation

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

Any problems with the GPS on the captivate?

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.

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.

Anyone else experiencing Sprint Nexus S GPS Issues?

I just received my Sprint Nexus S 4G from Sprint on Wednesday (moving from an EVO) and, of course, I've been playing with it non-stop. On the whole, it's amazingly fast and responsive - more so than I ever experienced with my EVO and a number of ROMs on it.
However, the one thing I have seen repeatedly since day 1 is that the GPS lock is abysmal. I wanted to say "weak", but no, it's much worse. I know the original Galaxy line was plagued with such issues but doing a general Google search for Nexus S GPS issues mainly revealed people wondering if the NS4G would have the same problem - not many reports of actual experience.
I can tell you that my EVO got GPS locks with nary a problem. If I was driving and had to whip out the phone at a red light to fire up the navigation, it was ready to go in moments. I did that a few times this week with the NS4G and was just annoyed. This morning was especially bad so I have been spending some time just opening up Google maps and hitting the location button to see how long it took to get a lock on me. It's truly something awful. The radius it shows is based on the cell tower estimate (I know from seeing where tower location usage without GPS pegs me when I'm at work on both my Hero and EVO) sits for MINUTES before it might get a lock on where I actually am. Even at that point, the accuracy radius is still huge compared to just being pegged where I am with the other phones I have/had. Then, with maps open, the phone goes to sleep (screen off) and I turn it back on a few minutes later and this starts all over again...
I'm actually surprised to find no real reports like this yet so I thought I'd prompt people to really take a look at their new NS4Gs and welcome a report from them. Is my unit bonk or is this more widespread? If you've got one, try it a few times throughout the day. Just open GMaps up and hit the location button on top right to get a fix on your position and take note of how long it takes to lock in to you.
(Before anyone asks, yes, in SETTINGS>LOCATION&SECURITY I have both "use wireless networks" and "use GPS satellites" checked off).
I've experienced this somewhat, although for some strange reason it seems to have tamed itself. The very first time I fired up Maps it locked on to me with a 20m window after about a half a minute, which I've found to be "normal" for AOSP. My Evo would get me within 2m and would do it in around 5 seconds.
The second time I wanted to use it, I used the voice control to ask for directions, at which point my stock Ns4G rebooted itself leaving me on the side of the road for a few extra moments before I was on my way.
The last couple days though, it's been decent. It still only locks within a 20m window, though, but it's been pretty accurate so far.
Actually, I think I am suffering from the same issue. From time to time, depending on the location I would lose service (yet wifi works) and the only way I would regain service back would be to reboot my phone. It's the strangest thing ever, I believe its a problem between the Sprint network and the Nexus S. My old phone would get full bars but on my Nexus, its been only 1 or 2 bars in 3G. Sprint better be resolving this issue soon.

Now that you mention it, using this phone the past 2 days... it's the first time in god knows how long that I've seen signal issues. The first one being low bar readings - but I attributed this possibly being a difference in display of the bars on this phone vs my EVO. On the Nexus S there are four bars total, gray and green. I'm usually at one - two green bars with this phone. On my EVO I had a lot more bars (maybe 6-7?)... so maybe my actual signal strength was comparable but "seemed" like it was better because I saw more filled bars. Again, a display issue? I'll leave that open for further investigation...
However, the thing that is really strange is that I've seen the 3G go to 1X numerous times. I don't know if I ever saw this on my EVO.
All related or no? Color me perplexed...
edit: During my Google searching earlier I came across a search result posted in the Sprint forums titled:"Signal Issues with Nexus S" - however none of the links worked because the site was under maintenance. It's come back online... from reading through it, this appears to be a widespread issue (general signal issues, not GPS).
http://community.sprint.com/baw/message/286393
So, do we have TWO signal problems with this phone? Ugh!
20 meters accuracy is the norm for me. not the best, but thats all i need it to do.
Tried it inside of my house, got 30m lock, pressed again after few seconds got 8m.
Radio problems have been reported on other forums too,
Signal strength is the same as my Epic, but nexus can't pick up 4G signal in the same spot where my Epic does.
And I get signed out of gtalk randomly, I guess its when it loses signal, 3G or WiFi.

Funny that you say that. When I had the EVO, coverage and download speeds over 3g werent a problem. now that i have my ns4g, same coverage but super slow 3g speeds in my area. not sure if its my phone, cuz where i work i get legit 3g speeds here and there. i'll give sprint a couple weeks to sort this out before my buyers remorse period ends.

From what I can tell, there's actually a difference between the white-ish signal bars and the green ones (it's probably in the manual but this would be the FIRST manual for any tech device that I didn't read front to back right when I opened the thing). Green bars mean you're connected to Google directly or something like that. White is just to the network. I tried to see the difference myself by going into mobile networks and disabling data - the green bars immediately turn white. When I turn the data back on they're still white for a little bit but I can get them green again immediately by logging into Google Talk.
Of course, the gray bars are still "no signal" bars as far as I know. White or green, I'm still only getting 1-2 bars of the four and going from 1X to 3G a lot. I thought I'd share that bit about the Green/Google connection because it might help you look up more info on that problem, too. I've already seen reports of people's connections to Google (lots of white, little green) being spotty, too.
It's too bad - this phone is really growing on me. It feels good in hand, perfect weight, looks gorgeous on or off... but the connection and GPS problems are a deal breaker. We need to see something happen. Really, REALLY disappointed in Samsung now.
Just got the nexus s 4g about two hours ago now and the gps has been great for me compared to the epic I traded it in for. Sitting at my desk on the second floor of my house and getting instant 2 meter locks. So far so good on my first pure google phone.
Sent from my Nexus S 4G using Tapatalk
I came from the Moment and it had 6 bars for signal strength....the Nexus has only 4 and from what I've noticed, reception has been the same or better than what I had. I haven't had any problems with 3G switching to 1x except when I was in our storage basement at work, in a heavily populated downtown. I haven't been able to try out 4G yet because it isn't offered in my area yet but assume it'll be the same or worse downtown. I have had issues with the GPS taking forever to get a lock, but I only use the GPS chip with NO help from the cell network. Most of the time, since it reboots in about 45 secs, I just reboot and it works fine for a while.
I did something slightly different. Before I used the GPS for the first time I completely removed google maps and didn't have any map program. I did have the evo shift sprint telenav map apk already on this phone. I installed it and started up the gps. After a few minutes of downloading files, the map screen came up and showed my correct position. I've found in the past if I fire up sprint maps for the first time I use the gps, it doesn't have problems locking afterwards. If I use google maps first, if it locks it takes a long time.

God bless you.. I had that paper weight for awhile and ditched it for the Epic. Worst phone I've ever used. The Nexus S must be like heaven compared to that thing.
So I was driving to one place today and needed gmaps to show me shortest route from my location, turned on GPS, could not get any sats to lock, I probably waited 20-30 secs and then remembered one old trick with GPS Status app.
Downloaded the app, went to tools, reset, redownloaded data, got 9 out of 9 sats locked on in 1 second, 2m accuracy. I can live with that.
But still not happy with 3G/4G performance, and at the same time I dont wanna go back to my Epic.
Mine locks instantly but up to 20m which doesn't bother me as long as it gets me where I need to go

Well, what I meant was that signal strength in "dBm's" was the same, or at least that's what both phones' status showed. But with speed test app 3G speeds on NS4G were MUCH slower than Epic's, and of course I couldn't even test 4G...
I'm also thinking if I should return it before 30days or just keep it and hope there will be fixes to make NS4G's radio better and better, to be prepared for ice cream desert, and then just jump to next Nexus

Yes, the difference is like night and day! I'm just amazed at the battery life...I can actually go a full day without nursing it with a charge here and there, the moment wouldn't go longer than 6hrs before crapping out...and that was with light useage! I've had the nexus for over a week and I'm hooked....and the GPS issues seem to have settled down, it locks within 30-40 seconds now and is pretty accurate.

GPS reception issues, but only while biking
OK I've searched around and haven't found much on this particular problem:
I use the MayMyRide app to track and log my bicycle rides. It consistently shorts my ride by at least 1.5 miles and several minutes, as compared to my computer on the bike.
This only started happening after I switched to the NS4G on Sprint from the Moto Defy on T-Mobile. I used the same app on t-mobile and it was generally pretty accurate.
Also, I seem to have decent GPS reception in general, the GPS lock times seem reasonable, and I can use google maps navigation with no problems.
Also, I've had this problem regardless of what ROM I'm running. I've flashed several, but I've mostly run Gummy, burnsra's CM9, and the latest Bugless Beast.
I've just started the process of flashing different radios, so I don't have enough info yet to see if that fixes the problem.
My hypotheses so far:
1) Poor reception in the rural areas that I ride, although since it's GPS I don't see why having poor network signal would affect it. But maybe it does.
2) Weak GPS antenna in the NS4G (?) (This doesn't make sense because GPS works fine in other settings.)
3) General sprint crappiness.
4) I don't think it's the app because it worked fine on T-MO.
5) I don't think it's the ROM because it's happened on several ROMs.
6) I don't have enough data yet to know if it's as simple as flashing a new radio. I flashed LC1 this morning so we'll see.
Any ideas?

[Q] To return or not to return (GPS problems)

As you may know by now I've been having problems with GPS on my Nexus S (i9023, bought factory unlocked from Amazon Germany, carrier code EUR, running rooted stock 2.3.4 AKA GRJ22). A quick search of the Nexus S forums will tell you that I'm not the only one who complains about GPS issues - I always assumed that the GPS was just sub-par on the model and I'd have to live with it.
Only now a few helpful souls over in the accessories section said it was probably defective and I should exchange it. (I've already exchanged it once for this and the new unit I got performed exactly the same.) So I'm just going to tell you the current situation and I'm hoping you'll tell me if that's within the normal tolerances for the model: [All tests done outside in suburbia]
"Network location" (geolocation, wifi / cell triangulation) is fine since 2.3.4 [just to get that out of the way]
Time to First Fix (TtFF) is decent now, usually 15-30 s cold and < 15 s hot. I've seen much better (yes, on a phone), but that doesn't bother me.
Accuracy however, is still bad. GPS Status shows 20-10 m mostly, but it fluctuates wildly going from 5 to 30 in a heartbeat even when it's just stationary. Other phones don't show this behavior. This translates into real-world problems in Maps (checked via sat view): The blue circle goes from large to enormous and back and while my true position is somewhere within the circle most of the time, the center dot is way off. Most other implementations manage to guess the location correctly even when the accuracy is bad (as tested side-by-side).
Stability is my biggest concern. The lock'll be fine for a few minutes, especially if the phone was just rebooted, but then the GPS will lose it every few (say 5-10) seconds and take time to reacquire it. Additionally, it doesn't pick up movement very well. I did a few tests watching my position in Maps while on the tram (in a window seat) and basically it would register an (approximately correct) location every now and then but then just hang there for a while. Usually it wouldn't register that the tram had left a stop before it had arrived at the next one or even just left it again. All other phones trace the tracks almost perfectly and in real time. There goes any kind of usable navigation and - in concert with the compass issues - all augmented reality apps.
Again, this isn't meant as a complaint or even a request for a fix (though if you have one I'll gladly take it) - I'd only like to gauge if my particular phone's have been bad or if "that just how it is".
Thanks for listening.

I even think my GPS is the worst of all the Nexus S.
Mine was bought from Ebay-UK and since it was on a repairing-tour to samsung germany i know its from CPW. Its a I9020 not I9023. BTW there was nothing repaired because they said "The discribed issue cannot be found" or something like that..
what do you mean with compass does not work for anyone?? does it really not work on any nexus? thats interesting, isn't it a little bit illegal to sell a device and say it has compass and than compass does not work at all?

the GPS on my NS behaves similar (but better) to what you describe in the first post but overall it seems to have better accuracy and stability.
Have you tried recording a track while in a car? The results should be better. At least with mine it's mostly accurate and rarely looses signal (unless you go under a bridge/tunnel)

Hello,
I have the same phone, NS4G from Sprint, and the same symptoms. The GPS worked fine for a week or so, and now I'm lucky to get it to work at all. Sometimes I can get a lock after 5+ minutes (while not moving), but other times it never occurs.
I just tried resetting the GPS as is described in the post above. It says "it will reboot automatically" - does that mean the phone or the radio?
In any case I just pulled my device battery after GPS reset - I'll post back with results in a few minutes. In the meantime can you explain what you did after following the reset with dialpad/MSL?
Also attempted return...had to send in for repair
I also got a bad GPS Nexus S i9020 from Amazon.com USA site. The GPS would not lock without a wifi signal. I eventually caved in trying to get it working with rom flashes, drove me nutz, but tried to return for cash and missed the date. Had to send in to Samsung then and get the repair. I have been somewhat satisfied, having gone from no GPS to finally getting it to lock, but its a poor excuse for a gps chipset. The SiRFSTAR from my old WinMo days kicks this gps in the arse.
I also get the bouncing sensitivity and wandering location circle, but accuracy hovers around 5-10m now, but the location is never fixed solid, its wobbly, even outside with clear skies above. The compass is another huge weak spot. Samsung dropped the ball on this device, I wish I could return mine and grab an HTC unit. Google should learn from this and drop them for the Nexus Prime. I think this is unacceptable as location services are whats hot now and this device fails as a flagship product.
I like the gps on my sgs2 more (it has a sirfstar IV) but, i have to say, it's not that much better.
What i gained in stability i lost in TTL. Sometimes you need one more than the other.
The SGS2 has taken me up to 10 minutes to get a lock and if conditions aren't good (cloudy sky, tall buildings) it can easily take 5 minutes. Sometimes you just want to get some signal to get you going.
I did a trip of more than 2000 miles with my Nexus S, using the GPS most of the time, and it worked ok enough for navigation for most of the time. The only times it failed me were, as i mentioned earlier, in old parts of cities with narrow streets.
You are right when you mention HTC, because usually their devices have better working GPS.
Overall i wouldn't say it's a bad device, you have to keep in mind this is not a dedicated GPS device, it's a smartphone that does a lot of things, some better than others, it's still a good developer phone, which i think was the main goal of the Nexus.
After upgrading to the SGS2, the main differences i noticed were not the GPS but the speed and extra memory! The Nexus S is not slow and has average memory (512mb but with only around 380 free) but if you have a lot of apps running (and it's easy for this to happen) it will get sluggish and begin to close the launcher when you start a heavier app. I found this had a lot more impact on usability than the GPS weakness.

My Nexus S isn't able to maintain a good GPS signal... What's wrong?

With 3G and the GPS antenna turned on, when I use Navigation the circle is constantly jumping around, sometimes it's big, other times it's small, and it never disappears completely leaving just the Navigation arrow visible.
Same goes for Maps itself, even while stopped it doesn't lock correctly. Is there anything I can do about this?
I'm not sure if the Nexus S has A-GPS, but if it does, I don't think it's using my carrier's data plan to help with locking the signal. I say this because after it has downloaded the map data, the 3G icon in the notifications area doesn't show the down and up arrows moving.
I'm on Android 2.3.6, completely stock and unrooted.
Hi,
Have u tried using Navigation/Maps app with WiFi turned ON?
It will gain accuracy of your GPS.
As for the GPS, it is a persist problem, you could retrieve lots of results by Google "Nexus S GPS"...
Some users suggest that use without battery cover could gain a much stronger GPS signal.
I encountered this problem as yours, plus with the compass disorder in Navigation app only.

I forgot to mention, I usually have Wi-Fi turned on anywhere I go, but the only network my phone knows is my home wireless connection. And if I'm using GPS on my phone, I'm not at home, so yeah...
Though if I try to use GPS on my phone, while connected to my home network, it gives me a much better result, though not perfect. It gives me a precision of 30 meters when connected to my home network.
And I tried it just now without the battery cover, and the results are the same, pretty bad.
I had the same exact issue with a previous Nexus S 4 G and I took it in to Sprint. I told them the GPS couldn't get a lock and when it did, it would instantly lose it. They tested it and issued me a replacement. They said the GPS antenna...or something in regards to the GPS (can't remember the exact name) was going bad.

Just to make sure, what is a "lock"? Does it mean the phone just having the arrow displayed, or the arrow with a circle around it on maps?
Because the latter is what happens to me, it never fails to "get" my location, it just isn't really that accurate...

When you open Maps and press the little circle icon in the upper right hand corner, the GPS is finding your location and locking you in. While its doing this the GPS icon in the status bar keep flashing until, the GPS locks on to you.
If it doesn't lock on you or cant, the GPS icon just flashing.
Now when I had my previous nexus, it never locked on me. But when I used navigation, it locked on after about 2-3 minutes but as soon as started to drive, it would lose the lock it had on me and display "GPS signal lost."
I used GPS toolbox to reset the gps calibration or whatever it does and that didn't work either.
So that's when I took it to sprint

Remove battery back cover will solve your issue
I've had this problem since updating to stock 2.3.6 too. My phone was fine on 2.3.4. This week I got the OTA update to 4.0.3 and it does seem to have improved things but has brought other problems - mainly with horrendous battery drain ...75%+ drain in 9hrs on (mostly) standby. Today I unplugged my phone 1½hrs ago, typed this reply and already I'm down to 74%.

My wife's Nexus is draining the battery fast. It wont last half a day. The GPS Icon is blinking and I have Wifi and GPS on. I think an OTA update ruined hers also

GPS icon blinking constantly is the main reason for the draining battery. Look for the app that is using it. Might be Facebook, Maps, or others running in the background. Close it/them.
turn off WiFi when not needed.
I get over a day of battery on a single charge with custom ICS.

Are you really serious about this
GPS takes a lot of time to lock for me irrespective of the ROM
The removal of the battery cover might slightly improve the signal but in my honest opinion it's mainly a placebo effect.
I'm having the same experience as the original post.
The problem is not obtaining a good satellite lock, it does that as it normally would. The problem is after it obtains the lock, it will jump anywhere from a mile to twenty miles away at totally random times.
When I get home and look at my tracks over the day using Google Latitude, I see that I was transported to various positions around Los Angeles at totally random times. It's really frustrating when I'm driving waiting for instructions on the next turn and the GPS says that I'm still sitting at the stoplight half a mile back.

Totally understand. I experienced the same thing with the i9023 version. I switched from ROM to ROM and constantly experienced the same issues.
However, strangly enough the signal seemed to have improved a lot after I updated to ICS 4.0.4 that was released just recently. If you can, get the update and give it another run. I've been turning it on while driving on the freeway to see how good it's been working - so far it's kept the lock fairly accurate and haven't gotten the lost GPS message.
And the battery cover was left on!

Nexus S has AGPS, and you can try to change an AGPS server. Please do a web search for more information.
For one reason or another when I first got my NS over a year ago I had to replace the first five. Out of those five there was one in particular that had GPS issues (took for ever to find a signal, frequently lost signals when driving, and just overall an inconsistent user experience), but the others worked amazing. Initially I would think it's a hardware thing, but seeing as though that other guy said 4.0.4 helped a bit. I'd certainly give that a go if you haven't already.

GPS Stopped working

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?
