My GPS has been working fine until I installed Cyanogenmod on my U.S. Cellular Galaxy S4 (SCH-R970). It shows the icon in the status bar when it is searching, but it never finds the GPS.
I have tried a few apps from the market (GPS Status & Toolbox, and GPS Status - Test & Fix, GPS Test). After resetting/reloading the A-GPS data, it still could not find my location. I saw that I could flash a radio to my phone and that may be able to help, but I'm not quite sure what that will do, or what radio to get or much at all about that part.
It seems like I am getting a few satellites in use, but not enough to get my location.
Anyone have any ideas for me? I would like to get this working soon.
Thanks.

Hi all,
I am trying to find out how widespread the GPS locking problems are with this model. I am talking about non-assisted GPS, which can be tested using the "GPS Test" application on the market.
So, how is the GPS on your phone performing using GPS Test? Please give some detailed information like lock time, number of sattelites, urban/countryside location, and if possible firmware version of your phone.

My Spica cannot get a lock at all, will see up to 11 satellites but most of them with signal strength bars at zero. Firmware versions tested (all same result)
1.5 (XEJB2)
2.1 (XXJD1, XXJD4, XXJF2, XXJC3)
Same pb with my wife's spica. Samdroid version with FE7.
Can't lock withour assistance. What a pitty.
Go to your Settings -> Date & Time -> Uncheck Automatic and see if it helps
Or you can try this (need root)

i can get a fix under 2 minutes if I stay still...moving, it can take an eternity

i just don't bother with that any more...I might do it again after a month without wiping any data
rooting is like breathing to me ... as it would be to most of the people here
Anyone found a solution yet?
My spica wont connect via gps either. It just keeps blinking and nothing happens...not even after 30min.
I've tried GPStest and it reports that 12 satellites are in view but non in use, and there is no bars everything is at 0...not picking any signal at all :S
I tried my friend's one too and he gets a signal imediatley and a lock after about 10-30seconds.
Any solution to this? Is it a software problem or hardware problem?

I installed the alpha CyanogenMod 2.2 and GPS is working like a charm!
Problem was with the wrong libraries being used in many of the custom roms found at SamdroidMod. Devs found out about this issue and fixed it in this 2.2 release.
I'm running original firmwire which i got on the phone. (XXJE4)
I'm not willing to install alpha cyanogen of froyo yet...Is there really no other solution? I've had a chance to compare my spica to another one with original firmwire (JE4 too) ant that other spica worked while my gps had no lock. Also i had the chance to try one with samdroid on and it worked too.
Mine works from time to time. at the moment it works, earlier today it wouldn't get a lock no matter how long i waited.
First thing-delete /data/xtra.bin- this is data for agps which seems to cause gps locking problem. You can do it with RootExplorer/SUFBS or any file manager with root rights. Or use GPS Status and Reset agps data from setting. You can also try to swap libsec-ril.so, JF2 version works best for me. If you want I can provide update packages for libsec-ril.so
i have installed cyanogenmod 7.1 on mine, and can get a lock under 1min30s outside or under 3min in the bus near the window.
I have a rooted spica with android version: 2.2.2, baseband version: i570EXXJC1, kernel version:2.6.29 and Mod version:SamdroidMod-2.2.2-a9.
When I go to google maps app and click set location I always get an error saying: location temporary unavailable ! I checked the option on Settings->Location and security->Use wireless networks and use GPS satellites. And my phone is connected to the internet.
I just bought the phone last week, and its really embarrassing not getting this to work.

thanks for the useful info, you saved my life by this post.
i thought my gps is wrong in my spica then it was just a bug in the cooked rom. cyanogen mod is cool and gps is working now perfectly.
thanks again!
With spicagenmod + hp/yonip kernel gps work very well.
Rooted my G1 yesterday for the first time and installed
GreenRomProject-Presents-CyanogenMod-7.1-D/S-08/06/2011
H-BOOT 1.33.013d
Radio 2.22.27.08
Everything seems to be fine EXCEPT my GPS isn't working - When I hit my location in maps it says to enable a My Location source in system settings - I have use GPS satellites checked and use wireless networks unchecked - if i check use wireless networks it will get me my location but doesnt solve the problem why GPS isn't working. Also when I use facebook and try to check-in with places, facebook crashes (I'm assuming its trying to use GPS and for some reason it can't).
I was having the facebook crashing problem prior to this and didnt notice if GPS was working or not prior to this so I'm wondering if something got messed up during the rooting of the phone or is my GPS somehow not enabled? I don't even get a satellite icon in maps or facebook. Any help ?
anyone ?????
try reflashing
Same problem here with Laszlo's Froyo, seems that switching on/off GPS in settings doesn't do anything. Normally I got a blue color on the LED, nothing happens there either.
Very fast MOD, but I definately want to get GPS working!

Try different ROM. See if you get the same problem.
Right, got it working. Don't know what did the trick, changed radio to v2.22.28.25 (from 2.22.27.08) and installed "GPS-test-plus" (gps-test-plus-version-1-1-3 from androidxmarket) after I started the gps-test program my location changed to the right one in my case from Holland to Sudan (!)
Maybe this could be helpful to anyone.
Glad everything works out.
Has anyone had this running on ICS i just cant get GPS to see it.
Yes, I'm running it on aurora 2.02. Some had problems in general with GPS location, and it can be fixed with GPS position fix app, like GPS Status & Toolbox from play store.
Also check the newest threads in development forum, you might find other useful suggestions.
Hey mate thanks sort of got it running can you explain how please?
Sent from my U8800 using XDA
Check this forum page, if you searched the forum you probably found it: http://forum.xda-developers.com/showthread.php?t=1511544
Find the section with GPS FIXES and detailed instructions will be there. Hope that solves the GPS problem.
I have the same problem with other navigation apps from time to time. Inside the program drag down the status bar and disable and enable gps several times, this way it works for me.
You could flash the newest test version of Aurora (2.03), gps problems seem to be solved. See the development thread.
I can't confirm, as I haven't flashed yet the new version.

The newest build 2.04 still has NTPS server set to asia. Otherwise GPS works OK. If you get long time for GPS to connect, put the phone on some surface, because hands can block some signal reception.
Just flashed 2.04, looks good so far.
I just tried GPS in my room, agps data deleted and no data connection / wireless. Set the NTPS server to Germany with the app FasterGPS. Well, it took about 5 minutes to get a fix with 10 satellites but it works Tested with GPS Status, Osmand & Locus Pro
No clue whats goin on...
I wanna use GPS and it keeps searching for ages without getting a fix.
So I ran GPS Status app and it shows many satellites - at one point I had fix to 8 or 9 Satellites?!
3 or 4 should be enough for a location, I don't understand why the GPS keeps searching without getting a fix when I already discovered 8 satellites?
Anyone have an idea?
My system is heavily modded (debloated hardcore) but I'm pretty sure thats not the real reason. Using xprivacy and afwall (but allowing the Android System and the apps I want to be able to use GPS the location and also internet access...) - this setup worked fine in the past on my N7000 without any gps problems. (even removed the NetworkLocation.apk since I dont want to use network location anyway and its not necessary for gps either - tested that already on my old N7000)
Satellites are found, but no location?! Really weird....

I think I have posted a similar story with my tests just today in another thread - does it make any difference if you have your mobile (cellular) data started (and WiFi off)?
I suspect there is somewhere a more extensive configuration for the GPS circuit (maybe including something about whether to use Assisted GPS or not), but for the moment I did not have enough time to look for more details on this
So, i can get a fix for my location and the apps which need location (like uber) works fine. But when i need navigaton like Waze or GMaps it simply doesnt get a signal, it says locating forever. I already used GPS Status toolbox to clear AGPS data and didnt work (the App doesnt locate a signal also). i tried TopNTP and didnt work.
Ive been having this issue for a couple of months i think, that is BEFORE i unlocked and rooted my phone for the first time ever (using DU ROM latest version, rooted and unlocked using NRT). Since i basically didnt used navigation i cant say for sure. But i think it was around the same time i changed my display on a cell shop, so maybe its a hardware issue?
Thanks for the help
