When i first got the DX GPS was awesome...but it slowly got unreliable....sometimes toggling GPS on and off would resolve it, sometimes a reboot...but now no matter what I do GPS will not pick up. I have even tried pulling the battery...still nothin.
Any ideas?
check what kinda apps you have going on, some of the tweek with the gps settings, my parents droid, really sucked when they had weatherbug installed or was it the weather channel app, one of the 2 was notorious for destroying your gps signal in other apps.
I don't really have any apps that use the GPS that I know of... and I never see the little GPS icon flashing at the top unless I am trying to get it to work.
I had to check 'Enable Assisted GPS' for mine to acquire a satellite with Google Navigations. It's disabled by default, doesn't seem like it should be required though.
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..

I think for many, it's still having problems on cold boots. Once it locks, it seems to be fine. I never experienced this though, I only have problems getting GPS signal inside buildings.

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.

^ Same for me. Never an issue and even locks indoors. Yes it eats batteries for lunch though.

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.

Gonna try this out! cheers
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.

exact same issue. drive an hour away and the gps is hosed unless you clear it and start it again.
I am also overseas. I wonder if grabbing the GPS settings from I9000 would help? Does anyone have them or know where to find them?
EDIT: nevermind they are the same settings

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.
Hello I'm having a problem with my GPS signal. I followed this guide to fix it but still have the problem: http://androidforums.com/threads/gps-fix-dummies-guide.761247/
I have NO PROBLEM getting my accurate location within 1-5 seconds when sharing location on whatsapp/telegram or other apps. Even opening Google Maps or Waze, they also detect my location very very fast. I'm taking less than 5 seconds and it's very accurate.
The problem comes when I try to NAVIGATE with Waze or Google Maps. This is when I'm outdoors in my car of course. My phone doesn't get a GPS signal. It takes a very very long time, sometimes 10 minutes to get a lock on. The funny thing is that when I followed this guide and I put the airplane mode on, the apps got a lockon on the GPS, but as soon as the airplane mode was off they lost GPS signal and had a problem locking on.
I have the GPS TOOL app installed and outside I get a lockon of about 10-15 satellites of 22 but it doesn't happen instantly. It takes from 10 to 60 seconds to get a lockon. But that is not even the problem. I could live with that, but the real issue is that the signal comes and goes. So sometimes the apps have a lockon for 1 minute and then they lose it for 3 minutes and again and again.
When I'm indoors it takes about 30 minutes to get a lockon on but I get from 1 to up to 6 satellites even though my apartment is the one on the top. There are no other apartments above it so I should have a bit more of a chance to get a signal. But it barely connects and sometimes never. The issue is the same. It may connect sometimes but it loses signal. 1 minute it remains connected and them loses it for 5 minutes and so on.
I attached some screenshots of how waze never has a GPS connection (unless I turn airplane mode on. I'll test this later on the road trying to get some place and I'll update if this really makes the GPS lockon but it's not ideal to have to use airplane mode to get a lock on GPS but not have internet for anyethign else). I have also attached the specifications of my phone. I hope you can help me out. It's a samsung galaxy s5 mini. And mainly I want to know if this could be because of the KITKAT firmware because I have read that many phones have GPS problems now, or if this could actually be a problem with my phone. I hope not becuase it's a new phone. I have one month with it and I'm in Mexico.
Thanks!!
Sorry, this forum covers all the standard size S5s but not the S5 mini. Try your question in http://forum.xda-developers.com/galaxy-s5-mini as there will be more people with the same device as you there.
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 .
