GPS after the update

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

I used the GPS for hours going between statelines with JI6, no problems requiring a signal when I closed out GPS.

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.

Samsung GPS fix. NEW!

ATTN #Vibrant users: We've created an app to help optimize GPS. Go to the Android Market & search for GPSSamsungRestore: http://ow.ly/3hEpr
Straight from their twitter about 10 minutes ago.
Update: Before anyone gets excited the app ONLY resets GPS to the original settings. Not a real fix as most of our GPS' were not working properly out of the box.

Don't get your hopes up.
# Does the application contain new values for GPS?
* No. The application only resets settings to factory defaults and then writes data in setting file.

Epic failure! As I expected it would. Tested this app and it tried to lock on 3 times before it gave me a message saying that I needed to contact a service center.

I have tested this application few times. I can officially say that it dies, while soft rebooting the phone, more times than to actually work. This application is as good as GPS itself.

Yes, I have positive results with it also. Used it and I got a lock instantly. Opened up navigation and it was spot on, no arrow jumping all over the place. It may say that it just reverts it back to stock settings, but whatever the case may be, it works.

edit: nm found it

Samsung gets pwned by XDA ... once again!
Two of the epic failuers of this phone is the lack of flash and improper GPS.

I downloaded the app as soon as i seen the tweet. It looked good initially, i got lock instantly, multiple times after running the app, but when I tested it out on a drive my phone would lose GPS signal after less then 5 mins, then it take another 7-10 mins to get another GPS lock, this kept happening the whole time....

Didnt make a difference. Still takes 2 or 3 mins to find my gps location. Nice try samsung. I mean WTF is the REAL problem with the GPS? I know! a hardware issue! EPIC FAIL!!

Hi, I have a rooted eco5 with absoluetly no bloatware. Whenever I use gps it says it cannot find me. Is there anyway to fix that? I've heard of an app that fixes gps, but I don't remember the name. Also I'm sorry for not using the search function, lol

Yes. Unfortunately the Epic suffers from a few GPS problems under EC05 and we're working on a comprehensive fix for them. However, we're still trying to understand exactly what folks's problems with the GPS are. If you're willing, you could be an incredible help with that.
Has your GPS ever worked prior to EC05? Did it stop working after you upgraded, and hasn't since?
Also, please use GPS Test when testing the GPS as it allows for the easiest understanding of what your current problems are. When using GPS Test, you'll probably want to go into Menu, Settings, and disable the "Keep screen on" option so your screen doesn't shutoff while attempting a fix.
Can you run GPS Test and report what happens? A "good" fix is when the "GPS on" light turns green in 10 seconds or so. A "poor" is when it takes anywhere from 30 seconds to a few minutes to get a fix outdoor in clear skies. "No" fix is when it's unable to get a fix even after 4-5 minutes of good visibility.
If you can report back how GPS Test works, we can debug this a bit further.

I can report on a rooted stock EC05 that GPS has stopped working altogether. Using gps test it never gets a signal. In Maps, the gps icon doesn't even turn on any more. Yes, gps is enabled under settings. This behavior first appeared after I installed Advanced Task Killer and I am not sure if ATK is killing some process that keeps gps from starting. Any ideas or any more info I could provide you to try to help figure it out?

So in GPS Test the "GPS on" light just stays yellow and the GPS icon in the notification bar just blinks? And this is across full reboots (power cycles) too?

It's probably unrelated to ATK. Did it work in EC05 prior to ATK?
We've identified a few issues with the GPS in EC05, one of which is that the GPS can crash and programs are no longer able to use it, but it recovers again after a full power cycle.
What we haven't been able to identify yet are the exact causes of why the GPS doesn't work at all for some folks. Mostly since everyone who has posted in the development thread now have working GPSes, so we no longer can get solid debugging info on them.
cmus said:

Yes, definitely. Are you familiar with running adb commands?
If you can, what would be really helpful would be to enable "USB debugging" on your phone, and reboot (full power cycle) it. Then, as soon as the phone is booted (network is up and it's done "Preparing external SD card"), plug in the USB cable and run on your computer in a command line:
Code:
adb shell "logcat -v time > /sdcard/logcat.txt"
That command shouldn't return immediately, which is what we want. Wait a few seconds, then run GPS Test and wait about 30 seconds or so. Then close GPS Test, and do a Control-C in the "adb shell" terminal which stops the logcat.
Finally, pull "logcat.txt" off your SD card and either attach it here, host it, or email it to me, I'll PM you the details.
Sorry it's a bit complicated, but that's the only way we've been able to get all the necessary information on what the GPS does from boot through a first fix attempt. If you have any questions about running that, feel free to ask.
Thanks!

Hi Mkasick,
so I just rebooted, and fortunately (or unfortunately) gps works. This is how it seems to go for me. It will work for a while on a fresh reboot, but after a while (maybe a day or half day) it fails to start again. When it doesn't work, the gps test behavior you describe is exactly right - icon says "on" and icon light stays yellow. So I assume the ADB logcat file is not meaningful to you if it works right now, correct?
I should also say that from time to time, toggling other radios using the drop down menu from the status bar also fails to work. Wifi specifically will fail to toggle on. Again, this usually happens after the phone is on for a day or so. Glad to hear that ATK is not the likely culprit because installing it has really improved my battery life a lot.
Let me know what I can do to help. You are awesome for working to make this phone better for the rest of us who don't have any coding skills. Should I get that logcat file the next time I notice the gps won't start?

OK, there's a few different issues that can cause that.
One is that the GPS will randomly crash upon exiting or switching away from a GPS-utilizing app, roughly every 1 in 20 times. When it does, the GPS no longer responds to any commands and the GPS icon will stay lit even after you close an app. We're finishing a workaround for this and I'll post it in the next day or two.
The other issue is that the GPS's ephemeris data appears to go stale earlier than it should. Here the GPS appears to work normally, with regard to icons blinking and such, it just can't use any satellites it finds for a few minutes, but if you're outside on a clear day it will eventually fix again. The existing workaround may address this. If you find the GPS won't fix, you can toggle the GPS icon outside of an app and that will download new assistance data which should hopefully help.

Probably not. Actually it might be hard to debug the GPS issues further until I get the crash workaround posted. In the meantime, you can at least discern if the problem is the crash by installing CatLog, and after the GPS demonstrates issues, open the CatLog and look for a line that says:
Code:
E/libgps (####): RIL Request: ERROR 1 (n=110, r=0)
The "n=110" is in particular a good indication of a GPS crash.

I've seen this on occasion too, but not frequently. I haven't had a chance to look into this issue further. It's possible ATK could be responsible here.
Mind running a few days with ATK off just to see if those issues continue to persist?

Thanks! At this point, I'm not sure a logcat will show anything new as long as your GPS does work after reboot. Probably the most useful thing would be to report if the existing workaround helps when your GPS stops working, as long as it's not due to a crash (which CatLog can verify).
I'll try to get that second workaround posted soon. This GPS crashing is annoying and hinders the debugging of other GPS issues.

So neither of the types of crash you describe really apply to what is happening to me. After my gps fails, the icon never comes on. Under the settings menu it says it is enabled, but no application ever gets the icon to come up and there is never any kind of message saying gps signal is lost or unavailable or anything like that. I will try to do what you say with regards to CatLog and send you whatever files seem relevant. ATK will be turned off.
Thanks again!

That could be a crash. If the icon is on when it crashes, it will likely stay on until "Use GPS satellites" is toggled, at which point it will turn off and stay off. If the icon is off when it crashes, then it never comes on again.
The status of the icon doesn't matter as much as the GPS is utterly unresponsive as far as the phone is concerned.

I've just posted the crash workaround. Feel free to flash it (gps_request_sync-EC05.zip in that thread). It's been tested on stock EC05 and SRF 1.1.0, althugh I think it should work on any EC05 ROM.
That alone may resolve your issues, if not, also try the assistance workaround in the same thread and we can go from there.

My GPS was working perfectly for months using the forced cold start. It has had the problem since the update to Froyo.
I tried this one and it is a "fail" as doesn't work at all after a couple of days.
http://forum.xda-developers.com/showthread.php?t=1028618
It seems to work at first but I think the "fix" has to do with rebooting the phone, as after a couple of days of uptime the problem of the Epic not using satellites that it sees returns.

My GPS randomly gets no lock without a reboot. This has happened after EC05 update. Now have Bonsai 4.0.1 and Genocide 1.0 kernel. This fix should resolve that right?

GPS issues..

The GPS on my phone has not been locking since I flashed CM7. I searched through some fixes but none seemed to help. I went back to the backup I had before I put CM7 on and the gps seemed to lock just fine. So I tried to flash while it had a lock but still nothing. I even tried using the GPS status app and that did nothing. Any other fixes that could help? Thanks

Have you tried flashing a different kernel? Maybe x99's or scaryghoul's as they are aosp roms their in the dev section. Always wipe your dalvik-cache b4 you flash a new kernel,I have very few issues when I do.

My GPS actually locks instantly after I flashed CM7 and x99
I have only one problem. Sometimes it'll lose a signal and will never get signal again on its own.
The quickest and only solution (that I know) is to quickly exit Navigation, then go in and tap on the most recent trip and voila, instant GPS lock again.
Not a huge problem, but a weird annoyance.

I assume you mean Google Navigation? If so I think that is a problem with Google Navigation itself. I have the exact same issue on my stock but rooted Shift. It will lose GPS lock, usually within the first couple of minutes. It then is never able to reestablish the lock on its own. If I exit Navigation and go back in, or turn the GPS off then back on it gets a lock and keeps it.
I just started trying Google Navigation. I have been using Telenav since getting the Shift about 2 months ago. With Telenav I never lost GPS lock.

i've found, atleast for me, that this tends to happen when i have GPS off, then turn it on to use it and open telenav and it just cannot find a GPS lock. so i leave GPS on and reboot my phone, open televav back up and it finds a GPS lock pretty quickly. it's like if i turn off GPS, i can't get it to work again until i reboot my phone...
needless to say, GPS sucks ass on this phone. i've never had a phone with GPS problems like this one. but other than that, everything is perfect.

mine happens when somebody attempts to call me, the lock disappears. after i ignore the call, like others have stated it locks on instantly when i go back into navigation. but i do prefer telenav over google... traffic is on point :]

i've been having gps issues, i think its a bug in google maps. havent had time to test root on it yet

It seems like nothing wants to work. I installed the x99 kernel and my GPS will still not connect. It seems like it will only connect when I'm on stock. For some reason I cannot get it to work with CM7.

Look up the ##gpsclrx# fix. I don't remember all the steps but it requires you to reflash a Sense rom, dial ##gpsclrx#, enter your MSL (found via MSL Reader on HTC devices), reboot, maybe clear cache, and then reflash your rom of choice. Fixed my CM7 gps issues (even with the MSL "password" prompt telling me that the password was wrong).

Nan to stock . Use GPS on stock leave it on. Nan to or redownload cyanogen and GPS will work. Happens to me when first putting in a rom sometimes.

I assume you mean Google Navigation? If so I think that is a problem with Google Navigation itself. I have the exact same issue on my stock but rooted Shift. It will lose GPS lock, usually within the first couple of minutes. It then is never able to reestablish the lock on its own. If I exit Navigation and go back in, or turn the GPS off then back on it gets a lock and keeps it.
I just started trying Google Navigation. I have been using Telenav since getting the Shift about 2 months ago. With Telenav I never lost GPS lock.

I have this exact same problem with Google Navigation. It "loses the lock" after a few minutes like clockwork, but I can get a perfect one again right after, making me believe that it is the application and not the GPS. Is there any fix to this?? It really is annoying.

I also have the same problem. Would be interested in a fix because it's very annoying.

[Q] GPS problem

Looked to the best of my searching abilities, and prob just missed something. However, is anyone else having a problem with the GPS? In particular, when I start an app, any app, that requires GPS, I have to turn the already on GPS off, then back on. Otherwise, even though its marked as on, the apps will say 'searching for gps'. Now, after I turn it off then back on, the apps immediately get a lock and operate as normal. I didn't spend much time with the phone before rooting it and have no idea if the problem existed before hand. Maybe I have a faulty phone? Or maybe I should flash back to stock?
If no one else is experiencing this prob, I'm thinking I should return the phone. Just need to learn how to revert back to stock with no one the wiser.
TIA

I've never had that issue. But i used GPS Status to clean the gps data and download more accurate one. It makes the signal stronger I think or we'll at least it seems to grab more accurate readings.
If you download it from the app store. Hit the menu button > tools > Manage A-GPS State > Reset. Then go back in and hit download.

Just tried mine again. Works as it should. I have GPS on all the time and when I go to map or navigation, it instantly shows my location and is ready to navigate.
The issue you are describing was common on my HTC Evo 4G LTE, though. That was pretty much the scenario anytime I wanted to use the GPS apps.

I use them on all my phones. It may connect good but I noticed on like navigation app it would bounce from spot to spot I was driving to. But when I use that gps status it smooths it out for me so it's smooth and moves as I do.

Found the program and tried what you suggested. However, I again had to turn the gps off then back on for even that app to work. I am going to figure out how to flash back to stock and try it again, then decide if i need to return the phone.
Thanks for you suggestions.

some of this could depend on the area you are in. downtown with skyscrapers = less accurate gps. Or at least in my experience. No matter what phone I have had.

Just a quick update:
Figured I had nothing to lose by trying one of the new roms that are out before I returned it. After flashing I went back to test the apps and they now work without a hitch. So, seems there was simply a software glitch preventing apps from seeing that the gps was already on and ready. I'm just relieved not to have to go through the extra steps to get navigation up and running!
Thanks again for the responses. Saved me a trip to test another phone! :good:

Glad this worked. what rom did you use? I am on uscc and have the same gps issue where you need to toggle it off then on and instant lock. Maybe we can extract the gps part and make a zip that updates just that part.

Exactly same issue with stock rom

I have exactly the same issue with the stock rom of my Galaxy S4 (i9505). Mine is not rooted, just standard. After having tried many things, I found the same workaround to switch off and on the GPS to have the navigation software working. This issue occurs with all software making use of the GPS signal.

i just unrooted my phone back to stock MDC did a factory reset.. rebooted now my GPS wont work.. location error.. failed location current location? i tried everything turn data on off.. wifi on off.. reboot ect..?? please help.. thanks

Sorry, never saw the responses posted and figured my situation was isolated:
Problem resurfaced even on new rom, so returned to the store for a replacement, no problems since.

Solution found
I found the culprit: After uninstalling Yahoo Weather, the GPS works just fine!!
