GPS aGps location fix issue - Samsung Galaxy Nexus

hi guys,
need your help on this before i get mad and throw my gnex out of the window.
im experiencing great problems with gps fix on any offline gps navigator like copilot or sygic. The gps fix is hard to get and even when it works its really wiggly m it goes on and off continuously and soetimes it puts me kms away from where i really am. Annoying.
Im on aokp build 36 / franco kernel and already tried the gps fix (i used faster gps) setting the server to europe/italy but no luck so far.
Does the agps activate automatically with gps? how do u turn on barometer?
is there anyone who can spare an advice on this? maybe updating radio?
thanks in advance!

Try using an app like gps status to download agps data before you go offline? I guessing you can't get a GPS fix because you have no data connection...

Gingervillain GPS problem

Hi,
I am having trouble with GPS on my desire since installing gingervillain. On both versions 1.4 and 1.5 GPS just doesn't seem to be working at all. I've tried a factory reset from the recovery menu and have tried re-applying the zip file but with no luck. GPS is enabled but I don't even get an icon on the status bar at the top when it is supposed to be searching for a signal.
Thanks,
Chris
Reach for the skies
Go outside of your house. Point your phone to the sky. Your position should should showing on your GPS.
Or it could be the program itself? Try different gps using apps like maps, facebook places etc etc.
Also do post what radio you're currently using on your phone. It could help people diagnose your problem better.
Tried outside and using gpstest off the market with no luck. I don't usually have any problem with gps inside my house anyway. I don't even get an icon in the status bar at the top it's like it's not working at all. And before anyone says yes it is switched on! My current version is:
32.49.00.32U_5.11.05.27
Any help would be much appreciated!

You must have the worlds strongest GPS in your desire. In normal ones, you need to be outside with the phone pretty much able to see the sky. On top of that, ideally it will need to be a clear sky.
Turn on GPS, open up Google Maps / your Navigation software (while outside). On my phone it only used to show the GPS icon in the task bar when a program was running that could use it.
Alternatively download GPS tools from the market (I forget the exact name).
If your GPS is indeed stuffed, take your phone back (if its under warrantee).
My GPS died on my phone. Completely. And before that it kept rebooting the phone. Had to take it back.

Same here too
Hi
very interested in this thread as my GPS worked fine until I installed Gingervillain 1.4 last week and then updating to 1.5 on Friday
Radio : 32.48.00.32U_5.11.05.14
I downgraded to GV 1.0 and my GPS was working ok again. I heard there was a known GPS problem fixed in GV 1.6 so I upgraded but the problem returned unfortunately. Any ideas?
Update the kernel with Villain set up, it cured my GPS problem.
GVChangelog:
Version 1.6:
* Fixed GPS problem (Thanks to CM Team)
+ kernel update defo works.

Hi,
Could you advise how I go about that? I thought the Kernel was updated as part of the gingervillain setup anyway?
Well I've had more fun with this! I just couldn't get GPS working on anything other than GV 1.0. I completely wiped my SD card and re-formatted the EXT3 partition. I then installed the stock RUU at which point GPS was predictably working. I then went through the flashing process of GV 1.6 and GPS was working this time. It was fine for a week or so but then the GPS stopped working again! I'm thinking it must be something to do with the dalvik cache now, that's the only reason I can think of for the GPS to stop working. I'm running out of patience with GV now so does anyone have suggestions for another stable 2.3 ROM I can move onto?
Thanks again,
Chris

[Q] No GPS Sat fix without Data Connection (aGPS)

Hi there,
first: sorry for the 1.000.000th thread about the GPS sat fix on the DEFY, but I have tried several ROMs now and still have not found the solution for my problem.
The problem is: my DEFY does not get a GPS sat fix when data connection is turned off (e.g. roaming or turned off manually). In GPS Status I see up to ten satellites (in grey or sometimes yellow colour) but even after hours I do not get the fix. When I turn on the data connection (either 3G or wifi) I get the fix in few seconds.
I have tried several ROMs now from Froyo, over Gingerbread to now CM7 RC0, but all show the same behaviour. I have recently downloaded the GPS fix from this thread: http://forum.xda-developers.com/showthread.php?t=953630 but it did not help at all.
I have deleted the /data/location folder, reseted the aGPS data several times, nothing got better.
I feel like sending the DEFY in for repair but then Motorola will check it with aGPS and send it back unrepaired because everything works.
So, if anybody has a solution or hint I woul appreciate it very much.
Thanks in advance...
HMM !
Same problem here
it is true, without agps data, very difficult to get fixed. That's why we need agps.
I have CM7, with GPS Monitor Free and AngelDeath's GPS fix 1.2.zip installed, I am able to get GPS lock in couple minutes without any Data (on fresh restart).
Give it a shot
GPS Monitor does not solve the problem
Hi there.
@teruyume
GPS Monitor did not help, it shows the same behaviour as GPS Status. Finds many satellites but does not fix!
Can anybody check if he has data in the folder /data/location ? I deleted it as stated in the FAQ for CM7 and the folder is not yet recreated. Might this be a hint?
I really cannot tell what the problem is: good reception (10 satellites) but no fix.
I have also been having trouble with GPS on the Defy. It will get a fix very quickly but moving the phone will cause it to lose its fix. It will go from having a lock on 8/10 sats to 0/1 to 4/5, etc. It won't hold the lock for long. I tried AngelDeath's GPS fix 1.2.zip and that helped speed up fixes, but it still drops the fix if the phone is moved at all.
@hartmuna
I made a backup of /data/location and then deleted its contents (not the folder itselft). Then I got no lock at all. I rebooted the phone and it automatically repopulated the folder and began performing the same as it did before. You might want to create the /data/location folder and just leave it blank, then reboot the phone and see if it will populate it again.
I also took a look at location.cfg and noticed a lot of settings in there that might be worth tweaking, but I have no idea what they all mean.
I found the data/location folder with terminal,don't know why it doesn't sure vida astro. deleted it again but that doesn't solve the problem.
I think I might give official gingerbread 2.3.4 a chance after the weekend. hopefully this will help?!?
Does anybody have experience with the leaked 2.3.4 and gps?
Sent from my MB525 using XDA App
I also had little problems to have the fix. And when I got (after several minutes) it loses during driving. The accuracy was too bad.
on CM7 rc1v2.
Anybody without GPS problems?
Hey guys, still no solution here. Tried every ROM out there.
One question: is anybody out there who does not have any problems with GPS fix without aGPS?
I am thinking of sending the DEFY in for repair...
With JBoogie3's blurry ginger rom I got 5 satellites used in fix in less than a minute (without internet). Try this rom before sending the DEFY in service.
same problem here, using last nighly and the problem still ocurrs, tried GPS-fix from angelofdeath but stil imprecise.
No solutions so far?
--
ive tried the GPS Monitor , he shows the lock, satellites, etc.. but, the gps with a "4 meters precision" put me on another street insted of mine, a mistake of ~50 meters (shows me on a paralel street instead of mine)
My standard Defy (still on Eclair) does fixes without Agps/data connection but after a trip of say 1000 km it can take up to 15 minutes to get a fix.
It also seems to help when I reset the Agps data first through GPS status (app).
GPS fix when not applying the UPDATE.ZIP
News from my side: I updated to CM 7 RC1v2 and this time did not apply the UPDATE.ZIP for my country described in this thread: http://forum.xda-developers.com/showthread.php?t=953630
And after few minutes I finally got a fix without aGPS data!
So my suspect is now the modified gps.conf. The original one is very short a has basically just the reference to the NTP and google aGPS server. The modified has far more lines that I have not yet studied in detail.
So, I will check the line of the gps.conf and try to find out what affects the GPS of the DEFY no to work...
Greetings from a happier DEFY user
That is good news. Would you be willing to copy/paste what is in your gps.conf file so that I can try updating mine without reflashing CM 7 and see if that solves my problem?

Sure, you will find the original.zip with the not modified gps.conf and then I installed the europe.zip from the above mentioned thread.
So far I am able to get a fix but for my patience it takes much too long. I am afraid that the GPS antenna of the DEFY is crappy.
Will do some more testing, any additional info is very welcome...

GPS not working!!

Until few days back GPS was working like a charm.
Today I performed an upgrade of Google Maps to 5.9.
And GPS doesn't work!!! Searching and searching, not able to fix satellites!! Outside, sunny day...
Uninstalled upgrade, rebooted phone, reinstalled upgrade....
GPS doesn't work! On old and new version.
Any ideas what can cause that? Anybody experienced similar problems??!! What a disaster!
only in Google Maps or also in other apps (car dashboard etc)?

When I use Google search it doesn't work either.
I don't use apps with location but just checked with WeatherBug and apparently it doesn't work either!
GPS working fine here on .368 update using Maps 5.9
This is crazy but after second reboot it works again.
It's so strange!

If you don't use GPS that often, a fix can take a long while. I'd suggest a tool like GPS Test to see if it's picking up a signal and what the quality is like.
https://www.gstatic.com/android/market/com.chartcross.gpstest/ss-320-0-5
Those bars will tell you about the GPS signal. If GPS would not be working at all the bars would be completely flat. If you get some bars, it should be a matter of time.

Well thanks!!
I guess nobody needs 2 GPS test apps, but if you do then i can recommend GPS status.

GPS keeps showing "Searching for GPS"

Navigation is stuck on "Searching for GPS". Is there a fix to this?
I know there is a fix around the forum somewhere for it. You might want to give us some more info like what kernel/rom you are running. I am RasBeanJelly and franco.Kernel lastest of each and my GPS locks on in less then 10secs. More info about what you are running will help us out.

I recommend switching to a different ROM such as Codename Android. Some ROMS have a GPS problem like you are describing. The kernel has nothing to do with it. Hope I helped.
Its coming on all ROMS D:
Still getting same error even after trying CNA. I even went to GPS settings and checked "Internal GPS antinna" or something. But still getting same error. Could the phone be faulty?
Have you tried either of these?

i have had instances where it was a KERNEL problem..not the rom...certain kernels couldnt lock on GPS..flashed a different one and it worked..flashed back to test it again and it didnt...so it was definitely the kernel causing it...so he can try flashing another kernel

I upgraded to 4.2 jelly bean.. and I have gps proble, always searching for gps..
I had the same problem with 4.1.2 and maps 6.14 but with 4.1.2 I installed back old gmaps app (6.12) and the problem was solved.
Now I have 6.14 maps ad default.. and the problem is here.. how can I solve it? thanks
For me even the gps icon is not blinking. How to find whether the gps hardware is faulty? So that i can stop trying other software fixes

sygic works so it's not a hardware problem.. other gps apps show me satellites.. but maps no!
Old gmail maps works but now I don't know how to install previous version.. can anyone help me?
Maybe it's a app problem (6.14 maps..)
thanks
Install GPS status from market and let it download agps data and point it towards the sky and see how that goes. If you see satellites and they lock, go back to maps; it should work now.
Some gnex came with faulty GPS module. I have two gnex and e first one I got had the problem and hasn't been fixed with several ROM, kernel and tools and GPS scripts.
Keep us posted

gps status show me satellites.. sygic works but google maps no!!
I don't think it's a hardware problem because with previous version of maps it works! so I think it's a google maps problem.. but I don't know what to do to make maps work!
This is a Google problem, it's happened once before to a ton of android users, it may have come with an alert "unable to sign into account" (that's how mine was this morning, plus searching for GPS. All seems well now.

Losing GPS signal while navigating

Hi,
I have a strange issue with my Gnex.
I used to run CM11 nightlies on my device, but I noticed that the device loses GPS signal while navigating (using Waze for example) and then it takes like 3-4 more minutes (if at all) to recover the signal.
So to test it, I flashed stock back (rom, recovery, kernel).
but I still have this issue. I cannot navigate 5 minutes straight without losing the GPS signal.
I tried to run GPSFix, but it didn't really help.
Any idea/suggestions what can I do?
thanks guys!

Is your device activated on a cell network? Gnex by default has assisted gps, so it needs a data connection to establish a fix. What you describe could happen as you leave Wi-Fi, have no signal, and it takes 3-4 minutes to grab the gps ephemeris data from satellites. Just a guess.
If this isn't your problem, have you tried using GPS status and toolbox app to Resetand redownload agps data?

Hey, thx for the reply.
Yes, I have a 3G connection and WIFI turned off.
I tried the toolbox, used it to reset data etc - but it didn't help
Well, the only way to truly know would be to flash a stock image and see if that works. If it doesn't, then you have a hardware problem.
Give GPS Test a go (search on Play store, I can't put external links here, it's the one from Chartcross Limited). It helped me a lot some time ago when I had your same problem.
