[Q] GPS not working after flash - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi,
I have a SGS with Orange in France
I was JF3 then i flashed to JM9 and noticed that the GPS wasn't working anymore, the icon appears and shows that the GPS is searching, but it never finds any signal and i can't have any location.
I tried JM8: same problem
JPK: same problem
With GPS test everything stays at 0...
The GPS was working well on JF3, I think it was ROM problem, but since i tried many different versions, it seems to be another thing...
Ayone has any solution for this ?
Thanks for your help!

I tried to flash JM5, but still no results...
And with the *#*#1472365#*#* command, i tried some tests, and the GPS never finds satellites...

Need to set it to cold start. Clear gps data. Go outside and run the get gps position test.

Okay thanks,
It finds one satellite, but all the above fields are empty...
No latitude, longitude... etc.
PRN [21]---> CNo 12dbhz .....

i had the same problem when i upgraded my firmware from JF3 to JG4

Ok it works now, seems like you need to be outside, i mean with no roof or whatever... then it works great ! With GPS Test i detect from 6 to 12 sats and pinpoint localization.
I guess i was a bit noob to GPS...

It will work marginally indoors once u get an initial fix as I outlined above and stay on same relative area.

[Q] Froyo GPS Lock Problem

Ok...so after updating to Froyo my GPS is not working. Not only that, my phone can't seem to find my approximate location even after enabling "Use Wireless networks". I used GPS Status app from the market and I confirmed the phone was seeing several satellites, but it was getting no lock. I had no problem with my GPS with 2.1 aside from losing my location occasionally when I drive through the downtown.
Is anyone else experiencing this issue? I'm running my phone on Rogers network, unlocked and rooted.

You didn't say what version of Froyo you are running but I'd change my modem file and use one of the alternate ones that DocRambone has. There's a thread on this but I find the ZSJPE (Hong Kong) version to be superb (and our company develops an app for the phone that uses GPS for golfers) - very quick, very accurate...
Oh I'm using JK4 from Bell..and kernel version 2.6.32.9....
Edit: Oh and I have also done factory reset/cache wipe...and it's still doing that...I want to see if I can fix this without changing the modem file or anything like that...
I'm having the exact same problem since upgrading to the official 2.2 release from 2.1
EDIT: Bell Galaxy S Vibrant, Unlocked and running on Rogers. Not rooted.

Ok...so I'm a bit relieved to know I'm not the only one out there...From the things I've been reading it doesn't seem to affect phones running on Bell networks..but shouldn't GPS be not affected regardless of the network you're running on? I don't see why it's refusing to get a lock...
I can't believe no one else is having this problem, maybe we're the only ones unlocking??
I was also having this problem. I updated to bell froyo using kies, and am unlocked using rogers. I loaded gps test, set it so it wouldn't shut off the screen, and let it run for about 30 min in a window. Eventually it got solid lock on a couple sats and it now seems a lot snappier to get a lock.

Ok, good news! At least for me anyway... I decided to try keeping my GPS on and let my phone to try and find my location..however long it was going to take. I don't think it took me 30 minutes but it took me good 10 minutes before my GPS found my location. I think the problem was because I'm having trouble getting location information based on my wireless network and updating to Froyo and doing a factory reset must have deleted my satellite schedule. Right now I'm just so glad to find out my GPS isn't broken! :-D You should try the same thing I did.

@sw411 Oh and you should try and read this forum about wireless network based location service.

Thanks Yeria, that sounds like the problem we're having.
I do find that if I give it enough time, It will get a pure GPS lock, but I'm not getting any aGPS (the network based)
That thread you link sounds like the solution, but unfortunately I can't seem to access the file they tell you to modify
I too have GPS problems right after upgrading to official froyo. And it kept getting worse when i tried custom ROM. I tried factory resetting and format all my sd card, cache wipe etc hoping that it will return to normal like when i was in 2.1 elcair but to no avail. I don't know if some bad code was left behind when i did the official upgrade through kies. All i can say is it was working fine when i was at 2.1 then suddenly went bad after 2.2.
By the way, my problem is my GPS lock kept of disconnecting every now and then thus rendering my GPS useless as it kept on displaying my location as "off road" even though i'm on a clear highway with clear and bright skies!
ahh, if I root the phone I can get to
/dbdata/databases/com.google.android.gsf/gservices.db
unfortunately, this phone doesn't have sqlite3 installed!! I need to try and find that
EDIT: Found a copy of sqlite3 and was able to push it to the phone. edited the db as people suggested! I'll have to test it on Monday

Based on what I have found so far, and assuming your aGPS or any other wireless based assistance features are not functioning properly, doing a reset and cache clear will not help with your GPS at all. I have read that the phone will try to download the satellite schedules directly from GPS satellites if you're using purely satellite based GPS option. It'll be slow so it will take longer to get a lock and that's why phone will use other means to shorten the lock time. Once the schedule is downloaded, they said there shouldn't be any problem until the schedule expires, at which point you will have to download the schedule again.
I think the reason you're losing lock frequently might be because your phone doesn't have a clear view of the sky..? I used my phone GPS to drive around Toronto, Vaughan and Mississauga last night for at least 4+ hours, and I did not have any problem.
So, I tested today after updating the db.... no agps still..
Anyone else still.having issues with agps?
GPS works, just no agps since 2.2

This is why I unfortunately have to use an old Tom Tom GPS!
i'm having this problem too. i finally got it picking up quickly on 2.1 but once i updated i haven't been able to ever get a solid lock. has anyone found a solution yet??
Now that my wireless location service is kind of working I thought aGPS should also naturally work but I guess not... My GPS takes a pretty long time to start up and I haven't found any fix for this..
It's funny because I didn't really have any problem with my GPS with 2.1 but now I do with 2.2...

CM7 GPS issue please help

Anyone from Australia using latest CM7? I'm having really hard time getting GPS to work... tried pretty much every modem out there but no luck.. GPS Aids didn't help either... even if I got a GPS lock, it gets lost once I started to move
Thanks in advance

GPS works fine for me. I'm on nightly 104 with the JV1 modem. I also used Faster Fix to adjust the pool to Oceania. Even without the pool fix I had lock from cold in about 17 seconds. With the fix it's about 12 seconds while indoors.
I should add that I'm on the Optus network.

I'm not from Australia but some of the nightlies give me problems with GPS as well. I think that GPS performance has to do with the kernel as well. I found on nightly 88, my GPS was on par with stock. 89, 90, etc. gave me problems with GPS losing the lock. Now I'm on 104 and GPS seems to be better again...
I'm currently using the KG3 modem (with 850 band), with #104 and stock kernel.

Galaxy S GPS Can't find satelites

I Deffinitly Tried everything, I tried the hardware fix, Change The Pool To Israel, France, Europe, everywhere, I tried the gps doctors , nothing works..
I just can't find any satelites, in the gps aid app when i press the GPS doctor it's telling me that the gps status is off.. is there anything that I didn't try and could work?
Please, I'm Desprit..
I Tried and the problem is at every rom
I'm Right now using ICS RC3.1 By onecosmic..

try gps status , to see if is an app error from navigator and other gps programs or RC3.1 probleme , and if are ICS probleme try first to flash devil led kernel
and a wipe cache
I though onecosmic's RC 3.X was only for the i9000 and not i9001.
Well I Tried and looked at the gps status, I didn't really get what am i sepoused to do there, I reset and cleared all gps data and downloaded it after wards..
the app didn't show any errors ..
Try to get GPS Aids from market. Had the same problem and that fixed my gps
Tried the gps aids too... Ain't working.. anything else?...
When I tried the gps doctor at gps aids, it showed me that the gps mode status is not working (the cube near it is red) and after trying the setup and the fix everything possibility it still ain't working... any idea?

Try to download the GPS test and install it, then go to settings and select clear agps, then update agps.
Oh and dont try the gps inside your house! Try it in the middle of the street! Gps signal is always reeeally weak or undetectable inside a house.
Unhappy to say, still didn't work!
Can you post the exact ROM and kernel version you are using?
Also try the following. Disable wifi, reboot phone, try GPS test.
I had GPS problems a while ago and the workaround was to boot the phone with wifi disabled. Something todo with init scripts messing up GPS/BT.
When in Google maps do you get the GPS icon in the status bar when trying to GPS fix?
try this http://www.youtube.com/watch?v=STlb...xt=C3c039cbUDOEgsToPDskJOGd0pTyqyB6SPWL6OcwDB
Better to just send it back to samsung for them to fix if it's under warranty. If not, just sell it and get another one. I really like my SGS but i've given up hope for gps. I've just accepted it doesn't work and be happy the phone's great in everything else (like sound). Was kind of gutted having paid so much for a phone with a non-working gps but to be honest i have little need for a gps so when i need one i just use a dedicated one.
Now I'm using RC4.2 ICS By Onecosmic, Gps Still aint working well, I do get the gps icon... but still, my location ain't really accurate and I cant navigate or anything..
I tried the video that have been posted, None improvment...
Is there any thing else?..
The GPS issue with the i9000 is a mystery to me. I've tried software and hardware fixes to no avail with GB based ROMs. However, when I switched to Slim's ICS ROM my device started to register satelites again with the GPS test app from the market. Despite this when I open the maps app it takes forever to get a fix, so long infact that I give up long before it ever does
Same issue AOKP Milestone 4 ICS. Nothing on GPS Status.
I use market app GPS aid.

Gps signal problems

So lately my 4x have been loosing the gps connection alot.
It finds it pretty quick at the start but tends to loose signal alot and after loosing signal then it can take up to 5-7mins to get it back.
I mainly use gps for endomondo and some navigation, but its still really frustrating.
Does anyone have any ideas or suggestions to what I might try or whats wrong?

You can test the GPS in "Hidden Menu" or use "Z-Device Test" from the PlayStore
https://play.google.com/store/apps/details?id=zausan.zdevicetest
That happends with all GPS programs?
I'm with Navigon Europe and its very good. CoPilot Live is good too. Never had problems with them.
Maybe it help to take a look here:

Hello, I have problem with my gps.
I have tried several roms but nothing. It does not work. Also, I have tried the gps patch with no success.
Furthermore I tried several gps check apps and my phone found 0 satellites.
I think that it may be hardware problem.
Any idea?
