[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.

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...

SGS/Doc's Rom Questions

Just cooked and installed a rom on my Telstra GT-I9000T handset and I couldn't be happier. The speed has more than doubled and I am free from Telstra refusing to release updates and their bloatware. Any way I have some Questions.
I'v installed Doc's 9.6.6 Rom and it's going quite well.
1. The GPS has improved but I think it could still be better. I see there is an APP out there called GPS Aids and I was wondering if it would improve my GPS functionality or would it not work with a custom rom like mine?
Are there any methods to make my GPS better? I feel that this is the phone's achilles heal.
2. I now have the option under settings > About Phone > Software Update. I guess Samsung or Google will make Gingerbread avaliable for the SGS soon. When it is will i be upgraded OTA with this software update feature?
3. Any word on when gingerbread is coming out and if/when it will be avaliable in the RomKitchen? I know it's in Beta testing at the moment. Can't be too long before it starts to get released around the globe.

1. You could try a newer rom/modem as they definitely help out with GPS. Currently on JQ1 I get a lock within 5 secs accurate to about 10m. You could also try Faster Fix from the market
2. Upgrade will happen when Samsung releases it.
3. Supposed to be coming out March but no one really knows.

GPS Aids do works on Doc's ROM. What it does is speed up satellite discovery. So in theory you'll see satellites faster, but this doesn't necessarily means that it will be locked faster.
On my SGS it takes an average of 20s to lock using LBSTestMode. Some navigation apps takes longer though (not sure why). Also as utsmaster18 said, fasterfix helps too.
Latest DOC's ROM is 9.9.5 (based on JS8) and I've read (can't remember what thread) that ZSJPG modem is very good. I'm using JS8 + JPY CSC + ZSJPG modem, with Damian Kernel. I have gps aids and faster fix and I do love the GPS performance.
2. I now have the option under settings > About Phone > Software Update. I guess Samsung or Google will make Gingerbread avaliable for the SGS soon. When it is will i be upgraded OTA with this software update feature?

I don't think this function works at all. Even on my stock ROM this was useless. At least for me. I'd say you'll be best served by the XDA comunity.

Rumor says it would be out this month. In fact there is a leaked beta ROM already out and many custom ROMS built on top of it. But an official *golden* ROM from Samsung, I think that even they (samsung developers) can't tell for sure.

This is my ROM:
XWJS5_Wipe-v9_6_6-23-29-22-04-03-rM9FJUquQU
I got the GPS working.
First I used an ap called GPS Status to reset my GPS data as Dialing *#*#1472365#*#* does not work for me.
After I cleared all my GPS data I used FasterFix to add the fix although I am not sure if FasterFix was necessary as maybe clearing the data was all I needed to do.
GPS is really good now though.
I also got the compas working in GPS Status. First time I have had a compas work on my phone.

I have a mate with an old Nexus phone and he recieves firmware updates OTA. I never had this with my stock firmware (2.1-Update1) but Telstra probably removed it.
It will be interesting to see if I am able to update this way.

I may be wrong, but I guess Nexus firmware comes from Google itself, while we have to wait for samsung to release it. That's why we probably won't get updates through that menu.
At least on stock froyo (JPY) that menu hasn't worked for me. Not even to tell that I was running the most updated firmware. All I got was errors connecting to the server, or some other words with the same meaning

I'm pretty sure you're right and nexus firmware comes straight from Google.

GPS Aids and Doc's Rom works well together and gave me GPS lock in 2 minutes or so.
That's with JPE modem.
Now using Darky's 9.4, JQ1 modem without GPS Aids and getting locked in under 30 seconds with Google Maps and Navigation.
But I'm not knocking ROM creators around here, GPS Aids and Doc Rom FTW!
And yes, Nexus handsets get OTA directly from Google, no mobile operators in the damn way.

I might try GPS AIDS.
The clearing the data method with GPS Status then using Fast fix has made my GPS super accurate but it takes forever to get a fix and actually start working.

Just another question. Not really related to the OP but my provider has released 2.2 and there is a new modem JP9. Is it worth flashing this to my phone. I am running JL2 and it seems fine. Has any one compared JL2 to JP9?

[Q] Unique GPS problem

Hi everybody,
I think i got an unique GPS problem in my Captivate,
The thing is, when ever i starting GPS program (GPStest, GPSstatus, AngryGPS...) the GPS symbol in the status line flashing for 3 second and disappeared... no signal and not even a weak satellite. Nothing. The GPStest keep showing clear windows. I tried every trick i could fine, every server, lots of program, and nothing seems to make this phone to find a single satellite.
When i do the tests with AngryGPS/LBST, the test just doesnt process to anywhere(keep showing me Starting test... or 0/30.. Weird!)
Required data:
I am on Europe.
The phone is unlocked At&t.
Firmware - original one(stock rom)
Kernel - 2.6.29 jetaek lee sep-11
Build - ECLAIR
Basebnd - I897UCJF6
Please, this problem is driving me crazy... the one of my main used pitcher in my previous phone..!
Thanks In Advance!

You will never have working GPS running that firmware version.

miztaken1312 is right, you'll be hard pressed to get any kind of GPS using JF6. You'll need to go to a custom ROM to get usable GPS. I can't speak for the other ROM's out there but I've had great success with Phoenix(Froyo 2.2) and Mosaic(Gingerbread 2.3)

Ok, i also tried to upgrade to GB 2.3.4 PilotXrom 3.5, and still, the same problem, no GPS signal at all, tests in AngryGps stopped 3 seconds after its start. Could it be a hardware damage? What other Rom should i try? Froyo one?

Turn your phone off and remove the battery. Tell us what the build number is. It will be 4 digits starting with a 10.

Definitely not a unique problem. I had a 1007 with gps like that. I ended up exchanging it for an 1106 and now my gps is prefect no natter what I flash. Your problem is hardware.

Yep, 1007 is your problem. I had one as well and traded it in for a refurbed 1011. However if yours is a refurbed 1007 then it shouldn't be a hardware issue.

[Q] No GPS-Fix

Hello there,
I have a huge problem with my GPS, I searched the forum alot because of this, but wasn't able to find my exact problem.
first of all here is my problem:
I can't get a GPS-Fix. I used some apps like GPS-Status and I can see like 3 - 8 satalites in range, but still cant get any fix.
here is what i tried:
-flashing ROMs like hell (MIUI, ICS, Darky's, Stock)
-used many apps like "fasterfix" "gps aids" ect. did not worked out for me
-factory resets
-dif. gps server
-waited half an hour, clear sky, driving in my car 70km with gps on
you guys have any solution for my problem?
is it hardware? and if it is hardware, why am i able to "view" satalites?
Thanks, Karl

Download "GPS test" and stay on steady one place, enable wifi or 3g go to settings of GPS test and hit update AGPS, go back and wait till you get accuracy (meters) activated and gets as low as it can be (30m-5m is ok). Now only you can go in car for 70km....
You can download "gps.conf" of your country reason to get fast gps locking search here in XDA

This is no help, as i said, i testet it with several apps, GPS Aids is nearly the same program. i see a lot of satalites, but my signal stregh i too weak, so i don't get any fix.
without a fix, i can wait years to get a accuracy meters.

What Rom/Kernel are you currently running??
Under MIUI Mintberry Edition, I had a similar problem... my magnetometer was also affected.
I Solved it by:
1) flashing platypus kernel
2) editing the NTP-Server used to "europe.pool.ntp.org"
3) install google skymap
After that GPS and Compass behaved normally.
Average time to get fix (with agps) about 10 seconds

atm i'am using teamhacksung's ICS build 14 with derteufel's kernel.
ROMs I had:
MIUI (many versions) stock - Kernel: glitch(v13), platypus(r17 - NEO)
ICS - stock - kernel: glitch pre 14
Darky's ROM
I used GPS Aids and fasterfix. in these apps I changed the NTP-server already
to check GPS i'am using "GPS test" from the market
even if i have 10 satalites in view, i dont get a damn fix

How much strength of signal you get on GPS test ?
If it is low you wont get GPS lock !
Next, take out back cover and press gently to the rod like thing next to volume controller and see if the strength of signal improves (if it does your GPS antenna is loose)
By the way where in the world your location is?

I have an average of 8-12 of signal stregh.
i think only a hardware-fix can help to fix it. so screwdriver out and pray

I tried restarting my phone and that got the GPS to turn on. But it wouldnt turn off itself whenever you exit an app like Maps or a GPS status app. The icon will continue to flash on the tool bar for a while and eventually turn of by itself. If you try to activate the GPS again you need to restart your phone.
Im not sure if this is a 4.4.2 problem or a unlocked/rooted problem. Ill try to revert my phone back to stock tonight

my gps doesnt have that problem..download an app called gps status, it shows how many satellites are in the field, then click on agps reset, then download then reboot..some people report this method fixes their gps, but doesnt fix mine ..keep me informed

I'm having the same issue lately after sending my phone to service to fix camera... My gps doesn't want to fix satellites. I tried reverting to stock (keeping s-off and unlocked bootloader) installed a guru reset rom and applied otas but no way till now. Last chance will be flashing a ruu, didn't have time yet but I'll do it in a couple days. I will keep you guys informed, if anyone succeeds in fixing it, please post how you did it!
Gps status sometimes sees satellites but signal is too low and never grows. I even tried tweaking gps.conf file a lot but no way...
Sent from my HTC One using XDA Free mobile app

Update: i tried with a RUU zip with android 4.1.2 and applied otas till 4.3 (that was the last one i received) on one of this upgrades camera was unable to launch but on the next one it came back. And no way to get gps working with any one of these upgrades. Gps status sees a number of satellites (weird thing, after every new flash glonass satellites appear with some sort of signal -- snr <= 1.18 --, until i reset gps data and download new agps files, then they never come back until i flash some other version/rom) but never gets an acceptable signal enough to lock..
Really don't know what else to try, i think i will send back to service..

Any update on this?
Im having issues with my GPS as well. I use the ViperOne ROM (latest) with the ElementalX firmware. When I try to use Google Maps the following will happen:
1) GPS will find my location ok and calculate a route ok.
2) I start driving and the blue arrow in google maps does not move OR it thinks im on a different road than I actually am. When it thinks im on a different road the arrow may or may not move...more often than not it just stays still.
3) I have driven for over 10min hoping it will eventually start to work but it doesn't.
4) The only way I have got it to work is to pull over, stop nav, close maps and try again. Generally on the 2nd or 3rd try it will start to work correctly.
My GPS was working fine before I rooted and installed a custom ROM. I will try wiping and flashing ViperOne tonight and use the stock firmware instead of ElementalX. Will report back to see if this works.

Nop no good still. If anyone has a fix for this it would be appreciated!!!

Same issues here after sending in for repair. GPS sees about 18-20 satellites per the gps status apps, but only fixes on 3-4 with weak signals. Tried a few gps.conf tweaks which help but seems that they're just using more of the AGPS data and not actually the GPS chip.
EDIT: Have tried a few fresh wipes and different ROMs, GPE edition, etc. - all the same. This never happened in the past :/

I have tried updating the firmware to the latest version and different ROMS but that did not help. However I discovered that in google maps if I select the walk mode my navigation will work! Unfortunately thats no help as I need the car mode to work.
I installed GPS Status and it locks on to plenty of satellites so im not sure why Google Maps (or any nav apps) will not work.
I came to the same conclusion as you. It seems like the phone is using AGPS and not the GPS data.

I did a little research the other day ...I can't find the link but I remember most of it..
Apparently one of the Google+ and/or playstore silent background updates mess up gps on google maps for HTC One.
Using the 'GPS essentials' and 'Gps status' apps you can actually lock on to all the gps satellites fine.
Also using navigation,like you did...also locks on fine.
Its the standard google maps over view and a few other apps that use it (like my bus map app) that are affected.
One work around is apparently (didn't work for me though) going into the google settings app and tinkering with Google+ settings. turning it off or clearing it or something.
This is a software issue. I'm on untampered pure stock.

So I have resolved the GPS issue on my device. I tried a whole bunch of things so im not totally sure what fixed it. I:
Removed HTC Backup using root uninstaller
Using Faster GPS set my location and added the TRUE flag to AGPS_Enable
Using GPSFix I waited until it locked onto a satellite.
Rebooted my phone then tested with GPS Test. My phone locked onto about 8 satellites.
Tried Google maps navigation and it worked.
So far its been 3 days, 2 reboots and counting. Hopefully something similar works for you.

If you're rooted editing the GPS.conf file fixes it perfectly. The default setting are just totally crap

And GPS has stopped working again. What a pain.

Go here. This is how I fixed my HTC one. It works on all android phones. The default GPS.conf file is rubbish

I tried the gps.conf file in that link. It seemed to be slightly better at first, locking onto 3 satellites with yellow SNR in GPS Test. But then I tried resetting and downloading the AGPS data with GPS Status and after it doesn't even detect satellites anymore.

Question to the posters in the thread. Have any of you dropped your phone before this started happening? I've gone through 2 M7s and the GPS stopped working properly after taking a nasty spill and have been unsuccessful in remedying the problem.

I have dropped my phone several times however it is in a protective case. My issue started out of the blue: one day it was working just fine, the next it was highly erratic...and has been since.
