[Q] GPS not working after flash

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...

This is frustrating, WHY can't I get this GPS to connect?!

I have never been able to use turn by turn. I've used Google Maps after enabling GPS and WIRELESS NETWORKS AND THEN WHEN i SWITCH over to Google Nav it says Searching for GPS....but yet it gets me text directions on how to get there and if I make a wrong turn it doesnt update with how to get there from the current location
Ive seen videos of people being able to use their GPS and Ive had this phnoe since last year. What in the hell...please help.
Baseband:
32.36.00.28U_4.06.00.12_7
Kern:
2.6.37.2
Cyanogen 7.0 RC2

If you can't use GPS in any application I would say it's hardware related and you need to send it in for repair/replacement.
I would assume you have the newest version of Maps and you have wiped and tried the stock rom already.
Can you provide logs?

Oh damn Im out of warrant :\
Im frustrated
and the weird thing in Google Maps, when I have GPS and wireless network enabled it grabs my location within about 500 yards of my real location but on Google Nav it says searching for gps and when I use the GPSstatus app it doesnt lock or anything it has that loading icon

500 yards is your network location. That would be flat out awful and useless for GPS. My GPS fix is usually in between 3-10 meters.
Download GPS status from the market and see what it shows.

Oops did not see the last line where you already tried the app.
As said before try a full wipe/ restore to stock if you haven't already. Other than that it will need to be sent into HTC to be fixed.

Ill try a full restore and report back

Not quite the same ....
I am getting problems where the GPS lock takes far too long, but it does eventually get there.
I am on:
Android - 2.3.3
Baseband - 32.50.00.32U_5.12.00.08
Kernel - 2.6.35.7-59423-g08607d4
Build - GRI40
All pretty standard stuff, the issue really is that it used to work great on 2.2 & earlier radios, so I guess the question is what is the best radio for 2.3.3 & GPS ?

If you don't have the same issue, then why post in the thread with a different issue? Start a new thread for a separate issue. Fwiw, stock Gingerbread radio is 5.08 which is what you should be using, not 5.12.

I think it's more of a CyanogenMod 7 issue since I couldn't have locked the phone with RC2 also. Try updating to RC4 it works for me now.

[Q] How is the GPS?

Hi Everybody,
I am very interested in purchasing the Tmo-US version of this phone when it is avaliable and I would like to know how is the GPS on these phones? How fast does it lock and for those who are coming from SGS, can you see a big difference in GPS performance? I am currently using a SGS vibrant on tmo-us and GPS is very bad on it. Thanks

better than thge galaxy s.
First time i used it it took like 10 minutes to lock on lol, but then each time after that pretty much instant (or close enough)!

Not perfect for mine, sometimes under the sky also cant lock any satellite or scan no satellite in car. But other people are getting pretty good result though. That's why i am not sure it's my problem or not.

I edited the gps.conf file for my location (not sure if neccesary, but had the file from my previous HD2 so figured wtf..)
gps locks in 15 seconds when outside

Mine is MUCH snappier than my previous HTC desire

Best gps I've experienced on a phone. Better than my omnia, hero and my wife's galaxy s, which is terrible

Thanks for the quick replies. I am sure with some new updates the performance will improve even better. I cant wait to get my hands on G2x now.

Also extremely happy with the GPS. Using MileageTrac everyday, and the GPS locks within 3-4 secs every time.

GPS is perfect. It locks satellites in 7-20 seconds. Accuracy is 5m.

so a few more uses and yeah still instant. thumbs up!

for those who got fast gps fix time, may I know what baseband are you guys using?

Can it be used for car navigation like the Desire HD? Anyone tried it?

I think I fixed mine.
Solution was (at least one among them)
- push appropriate gps.conf to /system/etc
- modify APN type of Mobile data to "default,supl"
- turn off wireless while aquiring GPS fix
My GPS now fixes within seconds with mobile data enabled.

Have any of you tried GPS Status? It helped alleviate slow-to-lock AGPS issues on my Incredible. If you launch the app, it forces a new download of the carrier's GPS file. GPS lock went from 2-3 minutes on some buggy ROMs to under 20 seconds.
It's not the most elegant of solutions, but it works.

yup, quite a few times works great.

I agree. Use it everyday. It seems more stable than the DHD with better signal lock.

The demo unit at the T-mobile store I went to yesterday had a horrible GPS.
It would freeze up google maps and wouldn't lock AT ALL when the satellite antennae was turned on.
With the antennae turned on, google maps worked, but the circle for your location was huge (obviously).

Were you trying to use it indoors or did they let you take it outside to test it out?

Did you try GPS on any other phones? Signal could have been bad inside the building.
Being a Vibrant owner, with all its GPS issues, I'm very interested in how the this works on the G2X before I consider switching.
Thanks.

Worked fine whilst I was out today. Only problem was a lack of a data connection.

I play Ingress and i too have issues with GPS and my HTC ONE.

Maybe a issue in the kernel... :/ hope when i root the phone this can be solve..

GPS 'lag'
I've been using HTC One for about a week and noticed when using navigation (e.g. Sygic) in my car the current location is not accurate but it sometimes points even 200m away. The GSP seems to be very laggy, especially when moving (drivig), but if I stand still it gets better - then the error is only 2-3m.
This is unrooted, unmodified stock phone. I've tried with the GPS Status to fix the location, but no success. Any hints what else I can do? Thanks.

I can confirm the above. GPS is not reacting as fast as my Sensation and is sometimes way off qua location. This is on a rooted, S-off phone with ARHD 11.0.
