Hello,
I have a SG Ace with the CyanoGenMod 7.1 installed.
The GPS only gives the position sometimes. I have tried GMaps, Navigation, GPS test plus and GPS status and none of them work properly.
Actually, only Navigation has worked twice and when it does, the rest of apps work too (just for a limited time).
It takes ages to work and the problem is not finding the satellites since I detect (with GPS status and GPS test plus) 6 to 10 of them. It seems like it can't process the data and calculate the coordinates.
Any idea of what could be the problem? Have you heard of same problem in others SGA with CGM7? Any solution?
Thank you very much!
PD: I haven't tried the GPS with stock rom but since it has work twice with CGM7.1 and detects the satellites I think we can discard that the GPS is broken. It is more like bad configuration.
EDIT: when I download the A-GPS info I NEVER get a satellite. This maybe a symptom of something.
Did you see the GPS thread in the Android Dev section ?

Same here, tried the above but still no GPS.
Installed GPS Test and nothing showing - put the phone outside not testing in the house.
Worked OK on stock ROM

Now we have a problem. I have tried almost every trick and nothing worked. I can't believe we are the only people having this trouble, there must be someone else.
Does anyone know how the GPS works? What is the algorithm? We should be able to find where the problem is located.
My GPS can find the satellites (from 6 to 10) even inside of buildings (2-5) and have worked twice, only twice but it went okay. Usually, it doesn't give me the coordinates, as I said, this only happened twice.
I think the error could be related to the next step, once it has located the satellites, what does it have to do? Synchronise with the ntp servers?
Also we can try a personalized gps.conf config file because the others below haven't worked.
I hope someone understand the GPS process better than we do and can help us.
Thank you all.
I provided 2 sets of gps.conf and secgps.conf and both also didn't work for you?
My problem is similar.I can't get any satellites until I reboot.even after reboot, it doesn't lock even after having more than 10 satellites.I have to restart the GPS status a few times before it locks

Tried the second set of conf files and left my phone outside for about 20 mins and finally got a lock but only about 80 feet accurate.
Thanks for the tutorial.
Not sure if you have the latest modem/radio. Flashing the latest might help if that's the case.

Probably being a bit dim but is that an FM radio and what is/where do I get the latest versions of the modem?
EDIT
Flash a current modem file in ODIN I guess?
Finally getting very quick fix times (inside the house) by following instructions in this thread:
http://forum.xda-developers.com/showthread.php?t=1239713
I think using Assisted GPS was the key though.
With assisted GPS, it is expected to have much faster lock

I have tried almost every gps.conf in the forum and I haven't fixed the Ace yet.
However, I discovered two things:
1) If you reboot the phone with the "GPS Active" option ticked and reset the AGPS data (with GPS-Status) you always get locked.
2) When you get locked as I said in 1), it always refresh the coordinates once per 30 seconds (a normal GPS do it in once per second, checked with a stock galaxy s2).
The 30 seconds refreshing is very suspicious, like a wrong value in a configuration parameter. Any idea?
I think the problem is in the cyanogen, remember this is a ported mod from galaxy s to galaxy ace so it was not originally programmed for this phone.
Good information, I suspect it's due to cyanogen too. Can't wait for the official cyanogen. I hope it will fix the GPS issue. It's annoying sometimes....

After trying all the possibilities:
- Installing stock (gps-ok) and restoring my cm7 backup NOT WORKING*
- Installing stock and cm7 from new NOT WORKING
- Installing different stocks versions WORKING*
- Installing mods (gingerreal....) WORKING
- Trying almost every fix with cm7 (gps.conf, fasterfix-apps...) NOT WORKING
After all, the GPS HAS NOT WORKED EVER* with cyanogen mod 7.1 RC1 in galaxy ace.
So I just got back to stock, rooted and reinstalled apps, configs, etc.
I have something to say: if GPS doesn't work to anybody with CGM7.1, this MUST BE in the specification rom page because for many people (like me) the GPS related apps represent a high percentage of use. People should be warned about this issue in order to install or not the rom.
Thank you all, you have been very helpful, as always in this forum.
(*) normal working means <20s to lock, refreshing every second, even when you turn the gps off and on again...
I use GPS extensively too

Hi all!
Please help me to solve the problem with GPS on my SGS2.
It doesn't work at all in any navigation app, though GPS test (app from market) shows, taht the device can see a couple of satelites.
My configuration:
2.3.4 android
Kernel: 2.6.35.7
Build: UnNamed ROM v1.2.0
PS
I live in Russia. Can it be so, that GPS works only in US?

I was having problems with my GPS as well where it would not lock on no matter how long I waited. I did not have this problem when I first got my phone and I'm not sure when the bug was introduced. None of the software fixes worked for me, including the ones discussed here, and the problem persisted across all ROMS, including stock.
Finally I found someone in a forum that recommended removing the battery while the phone was on. I was hesitant to do this for obvious reasons, but my frusteration drove me to desparation and I tried it. To my surprise the GPS works good as ever and typically locks onto my location in less than 10 seconds. Obviously if you can get the software fix to work for you, this is better, but this was the only thing that worked for me. Hopefully this will help someone else.

What should the agps settings in gps.conf be set to?
I already set ATT=0 and used Faster Fix, but still locking/fixing is very slow, sometimes taking hours.
Could this have anything to do with my location? I am in China now, have unlocked the phone so using on a local carrier. Last time I was in the US (using it with ATT) it worked great.
Solved - SGH-I777 GPS fix
The sirfgps.conf ATT_NETWORK_OPERATOR=0 did nothing for me on my AT&T SGH-I777.
I got that GPS fix app and gps worked but its full of spam adverts that show on your notification bar. They appear with a star infront of the spam advert.
I fixed it the old fashion way. By remembering how I fixed my AT&T Galaxy I gps issue.
in /etc/sirfgps.conf leave att_network_operator=1
change, SSL_ENABLED=1
save and exit
in /etc/gps.conf change the following:
SUPL_HOST=www.spirent-ics.com
SUPL_PORT=7275
save and exit.
now I get 7 second gps lock in Miami Fl.

Hello,
I'm seems to be having this issue since I've installed my first modded rom or Radio.
Cannot recall it just now.
It does not matter which rom I have installed but the only way to get GPS working is to reboot the phone. Since then the gps works ok for some time.
Does anyone experience the same issue? Any solutions?
Cheers

I can offer 2 suggestions.
1) Give "GPS Status" a try. Android Market. **Edit: use this app to download new GPS data. Can't remember exactly what it's called.
2) Go to this post (http://forum.xda-developers.com/showpost.php?p=8176243&postcount=1)and search for "GPS". There are 3 files. Europe, US and Asia. Try the one for your location.
Option 2 usually works for me. I think it is compatible with any ROM.
Thanks,
flashing the radio and Heroine seem to fixed the issue.
I will keep testing it in next few days
I would also suggest the app 'GPS Status and Toolbox'.
If that fails then try a different radio.
How did you get on after a few days?
Hi,
Yesterday I flashed CM9 resurrection edition (before that I had a 2.3.5 stock ROM) and GAPPS.
Everything seems to work fine, apart from the GPS function...
In 2 times I tried, it took my SG2 about 15-20 minutes to lock on to a signal (and after that it was fine...), but in all the other times, it doesn't get a lock on.
I d/l GPS status and GPS Test and I get nothing.
I tried the AGPS patch from here, but nothing seems to work.
I looked all over the net for a solution, but didn't got to anything useful.
Can anyone help?
Try to flash a newer CM9 Nightly. Many improvements have been committed since last resurection release.

Hi
I have a very annoying GPS problem - I have several colleagues with sgs3, and when I run the 'gps test' application I notice that my GPS isn't as good - it's quite bad comparde to their GPS.
My GPS takes more time to find my location, and it always 'sees' fewer satellites than my friends' devices. Their gps sees between 10-15 satellites, mine sees 8 at best.
I tried several ROMs (omega 13, omega 26, wanam 2.3) and nothing helped - my friends had wanam 2.3 and omega 13...
I'm really frustrated by this problem, anyone got a suggestion?
Thanks

Thanks @JJEgan, I tried it, flashing didn't work so I manually copied the files, I'll try this on the way back home.
However, I understood what is my main problem - when using GPS TEST app I notice that I simply don't get ANY glonass satellite, though the process 'broadcommemsservice' is running...
How come everybody else (3 sgs3 and 1 note) are using glonass and only I can't? is it another piece of hardware? or a software issue?

I had the same problem with Omega Rom. Flashing Stock or Checkrom solves the problem.

but i'll try it,

If rooted
System/etc/GPS.config
Compare with friends
If different copy theirs and replace your one. Backup you old one
Don't forget to fix permissions
I tried everything...
I installed Checkrom 5.5 and i applied @JJEgan suggestions which overwrited gps.conf, and fixed permissions afterwards.
my gps still sucks. i saw 1 glonass satellite for a split second, and then it was gone. i still get only 6-8 satellites while my friends get 12.
DAMN!
I've tested it again against my girlfriend's sgs3.
the signal reception strength is a bit lower for every satellite we both receive.
i guess it is a hardware malfunction...
Something similar happened to me. I bought the phone and the GPS locked in under 10 seconds indoors!!! Coming from a Galaxy S, I was blown out of my mind.
Then, I flashed a BTU ROM (which is not where I am) and GPS couldn't find any satellites. Now, I'd forgotten my CSC so I changed it to KOR (close enough, meh) and now it finds satellites although it still takes time. If you want to avoid the whole rooting mess, change your CSC to the right one (be careful to make a backup as changing CSC deletes all data).
Hello,
This is nothing new - this device has GPS problems with custom firmwares. However, I wanted to share my experience and thoughts and clarify a thing or two. Tried different ROMs, radios etc. with no success to get stable GPS for daily use with latest ROMs. So I discovered that GPS on older ROMs works differently than on newer ones. For example:
On CM 7.2 - GPS Status&Toolbox gets green even with one sattelite (fix/sat - 1/1) - it can get fix to 10+ sattelites but will never get a lock no matter how much time I'm waiting on it.
On CM 6.1, B 0.8.4, and probably stock - GPS Status&Toolbox firstly discovers sattelites (yellow), it needs at least 4 or more sattelites (yellow) to get a fix. Once it gets a fix (for example 4/4) it changes to green color and gets immediate lock. This is also how it works on my Hero and usually is pretty fast.
So could this be a GPS driver/software problem in the ROM and why can't we get it to work on CM 7.2 the same way it's on 6.1?
I really want to be able to use newer, beautiful custom ROM like HomICS, AOPK, but since there is GPS problems on them I'm stuck on 6.1 or stock.
Cm 7.2 is one of the few roms were GPS actually works properly for me, I've written much about my GPS experiances in quite a few threads and some of my own threads, have a look around, they might be worth a read.

Yes, I did read some threads even yours and tried practically everything mentioned there but without any luck. I've got a few locks with CM 7.2 but it was couple of times when I first flashed it (mobile network was active (3g), however, I dont use it, ever) and the next day it would fix to 10/10 or more but without any lock.
Even today I got practically immediate locks with 6.1. in 10 to 20 seconds. Frustrating that this is not working the same way on 7.2.
How about you, in GPS Status&Toolbox, is your device fixing to satellites one by one (becoming green) without getting a lock? Or it needs couple of yellows before it gets a fix?

I have found that GPS status and toolbox doesn't fully work with the legend, mainly using the clear GPS data and for downloading a-gps data. I used quite a few different apps and basically pulled my hair out through shear frustration till I found something that seamed to actually work.
I use GPS test by Mike Lockwood from the market, this seams to work for clearing GPS data and download a-gps, but generally don't use it as my primary GPS app,I use AndroiTS GPS test free from Alessandro Bonetti also from the market, but for some reason is very hard to search for.
Personalty on my device these apps are the only 2 that give me constantly good results were all the other GPS apps I've tried didn't.

What about your lock time in daily use, seconds/minutes/ tens of minutes?
I use cm 7.2 (latest nightly) out in the open my lock time can be any where between a few seconds (maybe like 10 seconds) and a few minutes (2-3).

To make things a bit more complicated, after using GPS once, I have to restart the phone. Otherwise, it will not lock again. The first time it will lock in under 1 minute.
On CM 6.1, B 0.8.4, and probably stock - GPS Status&Toolbox firstly discovers sattelites (yellow), it needs at least 4 or more sattelites (yellow) to get a fix.
