It seems that the majority of people have absolutely no GPS issues. But I notice every time that I factory reset, I can't get a GPS lock, which is absolutely weird. I can't acquire location on GenieWidget either initially. If anyone else out there is having GPS issues or Location issues then try this.
How to fix for both:
1. Download GPS Test from the market (the free one)
Run it, and leave it running until the GPS On light turns green and it has satellites in use and tells you the meters accuracy. That means a lock. This can take a few minutes.
After this happens, GPS locks very quickly even after reboots, very weird.
Now even after this, GenieWidget still can't acquire location.
2. Turn on WiFi, but don't connect to anything, you don't have to.
When WiFi is on, go back to the GenieWidget and hit refresh.
It'll find your location even though you're not on a WiFi network.
Now disable WiFi and it'll be able to acquire your location every single time.
Weird stuff.
damn... sounds like Samsung is STILL failing with LBS. It's very frustrating on my Captivate.
I turned it on before and got a fix in about 45 seconds. About the same time as my Slide.

It's a one time issue though it seems. I think actually it all depends on getting that 'first' lock. The phone will go to sleep if you wait on maps too long. So I just use that app, go into settings, and hit Keep Awake then leave it sit til it locks. After that, I can get a lock in 1-5 seconds every time after reboots upon reboots.
It locks just as quick as my Evo, 10-15 seconds for me. I use my GPS so much if its not getting a good lock I would return the damn thing over and over until it work how it should. Even 45 seconds is a stretch...my G1 locks faster than that...

Quite right. There's a big difference between "cold" and "warm" GPS startup.
When the phone is brand new, or after a hard reset, it will always be a "cold" start. The phone has no clue about where it is in the world, or even if it has the correct time. So the very first thing it does is to look around and try to spot any GPS satellites. Then it tries to download the almanac data.
For GPS to lock, quite a lot of data needs to be downloaded from the satellites. This takes between 30-60 seconds uninterrupted view of at least 3 satellites. If you're moving around, the view of the satellites may be interrupted, and the phone will have to start over again. This process can be speeded up a lot with A-GPS.
After the first lock, things go much faster. The almanac data is already on the phone, and the position of the last GPS fix is known.
The thing that confuses most people is that an Android phone will try to navigate by other means when there's no GPS lock. By cell tower, or by WiFi hotspot. Cell tower gives your location instantly, but with a very large margin of error. If your position is way off, then you're not navigating by GPS, but by other, less accurate means.
I actually can't get location from the cell towers >.< But yeah my GPS is locking in 1-5 seconds now.
Still no luck with above... will not turn green just stays yellow

Fix applied and still having initial lock issues...
Power off and back on to test initial locking...
Lbstestmode is taking about a minutes to obtain a lock, while maps and gps test is taking up to 15 minutes if used for initial lock.
Once the initial lock is obtained, all is fine until next power, or long sleep
Am I alone?
My gps settings are default except I have changed standalone to MS-based and accuracy to 100. What I do is if the gps isn't locking really fast, I delete GPS data then run a get posistion test for a minute or three. I usually get between 10-14 satellites. Afterwards, my gps locks on very quickly and accurately. The fact that I have to clear GPS data and re-run the posistion test leads me to believe (or should I say hope) that the gps problem is software based.

If I power off/on, I also have to run the get position test for several minutes, then all is fine. I'm not sure if power is what causes it to loose its data, or time plays a factor...

Yea I have the same problem. Time definitely plays a factor, because when I go to sleep and wake up I have to clear the data then run the position test. But once I run the position test, the GPS locks on very, very quickly and accurately, which makes me feel hopeful that an OTA update could fix the problem. But since I bought the phone off contract I have 30 days to return...so if Samsung doesn't official release a statement by then I may have to return this amazing phone

I installed flixster and it tried to locate me via gps and couldn't...after I closed flixster, the gps was still open (still trying to get a signal) and sucking my power... Looks like it may mainly be an issue indoors
The gps initial locking issue needs to get fixed soon! My wifi only iPad locates me every time in about 2 seconds
It's going to suck if this great phone is flawed by gps
Anyone having major GPS issues? Seems like it was worse than before. Took forever to get a lock while I was driving, had to stop and turn off GPS/back out of Google Nav, go back in. It got a signal for about 10s then lost it.. with full bars. Anyone else having this problem?
Mine still doesn't work at all. -_-
No problems here ... I usually have it off but whenever I need it, I've always gotten a lock immediately and flawless navigation using Google Maps. Absolutely destroys battery though
Took me 15 min to get a lock on a clear day outside on a fresh reboot and still was off on my location. My touch pro 2 never had this problem.. I could use it inside a building full of metal and still get a lock.. I love the Epic but I would not use the gps in its current state of function for navigation purposes..

No the opposite is true, the problem people are reporting, including those above, are on warm starts where, on occasion, old expired ephemris data is in cache and causes problem getting a lock in otherwise good conditions.
This is much tested and there is a good workaround. By setting the Epic to cold start you overcome this problem, it is stickied as the workaround on the large epic forums elsewhere:
Enter GPS debug/settings application by typing *#1472365#
click "Setup" tab
click "position mode"
Click "starting mode
Enable "Cold Start"
Back out.
Whats the difference between warm start and hot start
mine shows me and my wife in texas half the time and we live in florida, never did it before this update. seems to be picking it up from the wifi I use in my house, as thats ATT and they are SBC and i believe they are in texas, but i never rehooked her phone up to wifi and lattitude shows her in texas at different times and the thing shows me in texas as well, its like cell triangulation doesn't work worth a damn.

The GPS is worthless and can not be relied on. Yes, on occasion it does work and on that rare occasion, it seems to work well. However, on the five occasions that I have NEEDED it, it has failed me completely, NEVER locking on my location. These occasions have been outside with clear sky. When I use GPSStatus, it shows 9 sats but 0 lock. I just don't understand how it can see 9 sats and not lock at all. I have a >10 year old POS handheld GPS that with no network, no maps, no anything locks every time within one minute. Samsung must have actually had to try to f--- this up.
Yes I have applied the cold start "fix" and it has made no difference, sometimes the GPS works and most of the time (especially when I NEED it) it does not.
Using the cold start method posted by aero1, my GPS.... sometimes works. Sitting in my car on a clear day with full signal, the GPS can take up to 5 minutes to get a lock. If I'm moving, It will sometimes lock onto me but still say "searching for GPS" so it won't give me driving directions... even though it can see where I am.
In cases when it does work, it lags a LOT. Sometimes it won't update my position for a minute... which is useless if I have a turn coming up that I don't know about. It is always jumping to where I am every few seconds. Google nav on the EVO was perfectly smooth. It stuck with me around turns and never lagged. Always perfectly accurate. It is the only thing I miss from the EVO.
I've completely given up on the GPS and use my Garmin (/wrists) whenever I need something reliable

Same results I'm having now. Using the workaround (cold start) it's hit or miss whether I get a lock or not regardless of how many sats my phone sees.
I put it to "cold boot" and am still getting shaky results. I used it to find my way back to my apartment but it kept putting me on the road NEXT TO the highway and jumping back and forth. Did this again when I was returning from work during lunch just to see if it happened again. Yep, gonna have to lug around my Garmin from now on.
Just sad.
Try this, weird but is working for me.
I installed an app from the market called GPS test to test my GPS signal strength.
Whenever I launch GPS test and then run google navigation it locks on within 10 seconds. If I don't launch GPS test after a cold boot then it takes forever to lock on.
So far this has been working for me for a couple of days. Might be a fluke though.

I've got three epics which allow me to do extensive controlled testing.
before applying the cold start fix my results were as follows on all three when in perfect sat condensations:
a) about 75% of the time no problem with locks
b) about 20% of the time I was getting many sats seen and none locked (expired ephemeris);
b) 5% or less I was getting few sats seen where they should be seen (bad almanac)
I applied cold start method to one Epic and for several days never experienced a failure to lock. I applied cold start to second Epic and now both Epics with cold start applied have gone over two weeks without a single failure to lock. I am now testing some other methods of flushing out cache
Top me this points to main problem being cache which for me ahs disappeared with cold start -- although there are other GPS problems on epic)
Other issues -- not addressed by cold start fix -- are inherent low SNR, SNR thresholds, samsung hacking the difference between fine and coarse results (30 meter hardcoded), these can all cause problems with GPS.
That said there is absolutely a repair of the main cache problem with cold start, I now see my 3g light up every single time I invoke GPS, with non net based applications, reflecting an objective and factual assistance data download --and without cold start I often would see no data usage on invoking GPS meaning failure to pull assistance data.
I think I've updated my phone with something called Kies mini... I am trying to check my location with the gps but it aint even close to where I live!!!
Everyone talks about how satellites has their gps locked on to but I have no idea how to see that... with gps test.
HELP PLEASE! It has been always showing the same location doesnt matter which city I'm on! (before the update too)...
I think once I have tested this gps fix that was around, but then I went back to normal settings (i guess)... cause it didnt work
Now it it says that I have ECLAIR.UVJI6
I am new to all this
Search the market for an app called "GPS Test". It will show you all of the information you're looking for.
Well, I'm still having GPS difficulties with the newest update (Running Bionix 1.9).
ECLAIR.UVJI6 is the newest update, so don't worry about that.

I have GPS Test and GPS Status... The first one doest even move at all when I start the application and the second one on the bottom show it seems that is loading something forever. Where do I see the sats? Have no idea. From the second one I will guess that it could be that part that says "fix/sats" and right now is saying 0/2.
My goodness... The damn gps would so useful to stop loosing myself on the German streets
Nothing that I can do to fix it? Is there any news about if this is the last official fix for the gps?
My GPS was working great when I first odin JI6, now all of the sudden it just stop working, I try to odin it back to JI6 again and it still doesnt work so well.
I'm testing the GPS out right now. I've had the phone since wednesday, tried google maps and it's never been able to get my location. I just installed JI6 today and ran GPS test for the first time. I got 0 satellites for a couple of runs until my 3rd try where it eventually got up to 10.
Even though I get locks on GPS test, google maps/navi still can't pick up my location so it's useless =\
In my specific case, I found that the JI6 GPS update did not perform much better than the original version. Yes it was better, but certainly not as good as the JI2 update. So, I've applied the JI2 update and things seem to work much better.
Also, I've found that turning off wifi when making the initial GPS lock really helps reduce the amount of time needed to initially lock.
Good luck!
^ second that. Try to turn off wifi.

FYI - Ive had good luck changing to MS Based:
From link-
""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. Can the GPS work in autonomous mode? No, the GPS receiver requires the assistance of the network elements to acquire its initial location fix.""
i flashed bionix 1.9 and had more problems with gps than when i was running 1.5. atleast before it was sort of accurate... and found a couple sats after 2-3 minutes. but iwth 1.9... nothing and not even the correct side of the street (showed me east while i was way west). then i found someone who had a gps fix based on j12 and it was in zip so... i mounted that to me SD and reinstalled using clockwork recovery... now within seconds i get gps ... extremely accurate... AND... lock on to most of the satelites that are available. i love it!
Right, so here are my thoughts and experiences while using the new JI6 update:
1) Way more accurate than the previous couple of builds that I have tried. When the GPS does lock, it usually locks onto 10/12 birds and finds my location within 5-6 meters. Not bad! Definitely not as good as when I had GPS working via one of Eugene's Franken-Twiz ROMs (between 2-3 meters), but definitely good enough for daily navigation.
2) The fix for damn sure didn't fix any of the satellite aquisition problems that our phones have been experiencing. Typically for me it will aquire satellites right off the bat about 50% of the time. Other times I'm left waiting 20+ minutes for it to get a lock.
3) Solution I have found to get a quick fix. Type in *#3214789650# (for the new JI6 update) and delete the GPS Data cache. I think it's the last button on the list. After the cache is cleared, use the top button on the list to perform a location test. I've seen this take anywhere from 30 seconds up to 2 minutes... sometimes a bit longer if I am in an area with poor signal coverage. Once I have aquired a successful lock on multiple birds, I simply back out of the application and am good to go. If I leave GPS constantly on, I have found that my phone will maintain the lock almost indef. If I turn the feature off during the day to conserve battery life I have found that it will usually aquire a lock within 30 secs or so of me turning GPS back on IF I am still in the area where I turned the feature off. If I drive to an area an hour or so away from where I turned it off, I usually have to repeat the above process to get a quick fix.
I've tried every iteration of option combinations from the lbltest menu, and have mostly been greeted by similar results, with no one option particularly speeding up the process. Based off of this I am assuming the issue probably lies with the caching of stale data on our phones, and it's inability to purge this data on it's own.
The one thing I haven't tried yet is the JI2 fix mentioned above. I might give this a whirl and see how it works!
BTW, I'm an expat working in Europe, so this might also be the cause of my slow lock times... however every other GPS I own works magnificently over here.

That's the first "fix" for the gps? I tried once but it didnt work.
I have tried pretty much all the "fixes" I can think of and this is what I have found. No matter the source (root mods, Bionix, J12/J14/J15/J16-leaked and OTA), changing from 'standalone' to msbased helps tremendously. Also using the google server and port is much much better for faster locks and maintaining lock even if you are not in clear view of the sky (tree, buildings etc will affect you lock). I willl say the stock JFD with the msbased and google server and port was better than just about all the other ones I have tried with the stock standalone and spirint server.
IMO The OTA J16 is the fastest and most accurate (less than 10 feet everytime, less than 30sec fix everytime) that I have tried, but even that required me to use the google server and port, and also switch to msbased.

finds sats but won't lock on...
I'm still having GPS problems post-update. I've never installed any custom ROMs or any custom GPS fixes other than some tweaking in the LbsTestMode menus, which I have since reverted to the default.
In the LbsTest or the GPS Test app I get the same results: the phone always finds 10-12 satellites just fine (levels in the 20s) but it never locks onto my location. GPS Test will say "In View: 10" for 20 minutes but "In Use" always stays at 0.
Anybody have any ideas here? I was really hopeful that I'd finally have a functioning GPS after this update.

the thing is... mine worked in the states with the stock JFD without any problem. flawless.
it stopped working when i got overseas. and hasn't worked well since. It really seems like it ONLY works well in the states. I mean I can get it to work if I clear the data all the time, reset the phone all the time, but it's not supposed to work like that. It should just find me when i open maps like any sound person would expect from the device. can anyone contend? is anyone having flawless GPS functionality outside the US?

I've rebooted at least 5 or 6 times, as well as clearing the GPS cache ("Delete GPS Data" in LbsTestMode) numerous times as well. Still never gets a location lock despite seeing 10-11 satellites.
Anyone else having issues getting a GPS lock? I'm sitting inside a building but my Hero would always lock here, especially after resetting the AGPS data with GPS Status program. Tried that with the Shift, and still not getting a lock even after a minute. Not sure what else to try.
Typically I keep mine turned off, but I just turned mine on and went to Maps and it locks my location in.
mine took a little while to initialize (indoors) but it locked in within 30 seconds.
No issues here. Inside my GFs apartment it locks very quick and is probably about 5-10 feet off according to google maps. My moments GPS never locked or worked so I'm extremely happy with the GPS quality on this phone.
The first lock took around a minute to get. Now it gets a solid lock in just a few seconds, if that.
A little off. Not as bad as my gfs Samsung Instinct, but it does often have me a few hundred meters from my actual location.

GPS is spotty for me as well. GPS Status won't even get it working for me when it won't work.
When it does work it is not as accurate as my Heroc was. Hopefully this gets some love in any updates.
GPS is great for me. The only issue I've run into is that when I go from Maps to Navigation, my SD card gets mounted as read-only for some reason.
I know a couple of days ago I tried to use my Google Maps/GPS and it couldn't get a lock on me. It was like going crazy or something. However, it was snowing and kinda foggy so maybe that had something to do with it. It worked the next day though when the sky was clear.
No gps lock on my end either. Also tried the gps status clear....nothing so far
EDIT: just opened maps for about a minute or so and it locked finally. Closed maps then opened again, locked within seconds.
Bumping this thread: I have issues with getting a GPS lock. If I open Google Maps, I'll never get a lock (at least not before the phone goes to sleep - 60 seconds). I open up GPS test, which I downloaded from the market. It gets one satellite to lock right away. Sometimes two. Then it takes forever to get 3-4 more (at least 60 seconds). I can then go into google maps, and it will get a lock within 15-20 seconds. But if I let the phone go to sleep, and open up maps again, I don't get a lock, unless I do the GPS test. And sometimes that doesn't even work. I've done the GPS Clear thing, via the epst codes (##GPSCLRX#), and that doesn't seem to do anything. I'm running the MikShiftG 1.1 rom. I'm going to make a nandroid backup, and see if that happens on a stock 2.3.3 rooted rom.
Hi everybody.
I have SM-N9005 phone, currently running Temasek V16.0.
My GPS usually works fine, however sometimes it finds the satellites and uses them but doesn't get GPS fix for a long time (actually - never, as far as my patience go, which was about 15 minutes). After rebooting the phone the GPS fix is almost instant, with no problem.
So, what can cause GPS to be unable to get a fix, while it can use the satellites. Seems to be software related as reboot makes it fine. It is not ROM related, cause I've had it on stock as well as custom ROMs. Anybody can think of a fix that doesn't require me to reboot?
No, I have given up on GPS of this phone, Snapdragon variant. As you said, rebooting the phone makes the GPS lock fast/ instant, but for normal usage sometimes GPS just won't lock. All I can gather from my personal experience is its about Assisted GPS. When you are restarting your phone the AGPS data is being downloaded automatically, that is how Android works anyway, and that's probably why the phone gets a super fast lock after a reboot. Use app like GPS Status or something to have the phone download AGPS data at short interval, see if that helps in anything or not.
However I have never had any problems when I am outside, the GPS locks within 30-45 seconds no matter what, its the inside problems which used to bug me, but as I said, I have given up.
Hm, I've never seen such a problem. I use my N9005 for travelling across Europe quite often, and it usually locks within 10 seconds to 2 minutes, depending on the location and the number of satellites.
Aside from the occasional glitch, of course. Like going backwards or sideways. :silly:
And it seems to think I'm somewhere off the coast of Norway right now. That one creeps me out quite a bit...
The thing is that when you reboot, it uses all available connections to pinpoint your location. Including your mobile data. (And WiFi if available.) So if you turn on location services right after rebooting, your approximate location is still in the cache.
Triangulation Over Data works within seconds, as opposed to the time required to lock on to the satellites in orbit when it is only allowed to use GPS. If you turn on the higher location modes, it locks much quicker. You can turn it back to GPS once your location has been established.

I am talking about GPS only. I use GPS Status app for a long long time (with my previous Android devices as well), so I can monitor the GPS fix. After reboot I get GPS position almost instant or sometimes I need to go into GPS status app and re-download A-GPS data (which is max 1h old, because of my settings) and then I get my fix.
When my problem occurs NOTHING (short from reboot) can get it to get a fix. I tried deleting and downloading A-GPS data, turning location on and off and from high precision to power saving - it just won't work. Of course I'll get postition from WiFi or cell towers, but GPS just won't fix, even with 12 satellites in use, after waiting over 15 minutes (which should be more then enough, cause whole GPS almanach is transmitted over 12,5 minutes and I get it from A-GPS anyway).
I would start by wiping the phone installing stock rom and testing . Still a problem then its hardware .
