Did the latest firmware fix the GPS issue?

I can't seem to find a straight answer to this so I'm starting a new thread.
With the JF3 firmware the GPS on my 2 phones is often not very accurate or completely loses it's position under what could be considered good conditions for a gps reciever.
Did the new firmware fix this problem?
Please only reply if you actually noticed the problem and can compare it with the new firmware.
Using GPS test is the phone now able to use signals with an snr of lower than 22?

No, it refuses to use GPS with snr under 22, as long as you don't locked them when they were higher. In that case it keeps them downto snr 17, and then drops them.

No and no....

Well that sucks, let's hope it's not a hardware problem

In contrast... I just flashed G3 and my GPS now locks in about 5 seconds.
It doesn't lock below 22... But for me it now doesn't need to.

Mine also locks in a few seconds, but it loses the lock again after a while. Then it locks again, the lock disappear, and so on. Completely useless as navigator.

This is quite worrying, because it suggests more than just a firmware problem.
To those who have flashed and it hasn't worked, some suggest flashing using the repartition option.
But this experience is why I don't want to flash my phone. If there's a hardware error, I can't rightly be taking it back.
Might get a HTC Desire and put the extra few quid up towards a 32 Gig memory card.

on further testing... My phone does use satellites of 19 to 22... But only if it is connected to less than 8 other satellites.
And I don't seem to have a disconnect issue.

Yes the problem isnt that it wont connect but that the thing often thinks you are on an offramp or a road next to the highway you are travelling on because the sinal is too weak/inaccurate. I tested this with 3 different nav programs and get the same result.

Let me get this straight, using GPS Test, you do see orange satellites through regular use?
This is all beginning to make sense now.
Unlike HTC which seems to use a GPS chip that is capable of 12 Satellite fixes, Samsung is using a GPS chip that can only lock onto 8.
I would think therefore that what it is trying to do, is to select the 8 strongest satellite signals which means it's already at a disadvantage, because as soon as you walk behind a tall building, it has to work to try and find and lock onto others. But when you walk past the building it goes back to the other satellites.
This probably explains why everything is jumping around. Because it's not using the weaker satellites in the distance until its too late.

Maybe you guys have the problem of "you hold it wrong"
when I put the phone's face upward, I got only 2-3 satelline locked
stick my phone up => 10 satellites locked and most of them are green
cheers

No - I have installed JG3 and still have the same problems. GPS is practically useless.
Its nice I still have my HTC touc hd - I get a pinpoint lock immediatelly.

Have you tried to use an external bluetooth GPS device ?

Don't think it's possible to use an external gps with android. How do you tell the os or app to use the external one instead?
Sent from my GT-I9000 using XDA App

JG3 seems a lot better for me. Still not perfect, but better than previous versions were I only lost a GPS a couple of times opposed to ALL the damn time !

Well guess I just need to flash my phone and try it myself. I wish Samsung would just release an official update already.

I got the code of this website. Why would i lie? I've had my phone like 2 days and i was sick of getting no gps so i went on the hunt for a fix and there it was.
Google skyhook if you wish.

Anyone else tried playing with the accuracy value in that menu? It seems like it has an effect on locking satellites but I'm not sure.

Sarcasm never translates well over text... Unless you use italics..

getting a lock is a minor problem compared to MAINTAINING an accurate lock, does this fix address that issue or just the lock on time?

Well I gave this a shot, and now the GPS doesn't seem to function at all. The market tool GPS TEST, Navigation, Latitude, and the built in GPS testing tools (from the phone menu *#*#1472365*#*#) all hang requiring a force close.
But this is really no worse than the largely non-functional GPS I had in the first place so I'm not bothered.
UPDATE: Using "Fix Permissions" from Rom Manager fixed the FC's.....will be testing GPS now to see if it's any better.
UPDATE#2: Taking my daughters back to my ex-wife (oh the joys of divorce) I ran Navigation during the trip, letting my oldest daughter drive so I could pay attention to the accuracy. It took a good while (about a minute) to get a proper GPS fix, but once it did it remained accurate during the entire trip except for one instance where it bounced a few hundred yards off the route for a couple of seconds. This is a marked improvement over my previous experiences where it would bounce off route like that numerous times during a Navigation run.
So...better...but still a bit less accurate than I'm used to with other Android devices.

Italics you say. Nice I'll give that a try next time.

Tried it. Got a fix in about 5 seconds indoors and pretty accurate. The compass is still all over the place. But as for accuracy it helped a lot thanks eugene.

I changed mine to ms-based and it works well. In certain buildings, however, it cannot get a lock on any satellites even when it detects as many as 10.
A weird thing that started recently is that in lbdtestmode, when running a position test, it takes forever to get a lock or sometimes to even find satellites. However, if I open google maps, it proceeds to quickly lock my position with 10m accuracy. Then if I run a posistion test it finds a 8-12 satellites and locks on quickly.
What is weird is that it used to be the opposite: I would have to get a lock in posistion test before google maps would get a lock. May also just be a coincidence or a placebo effect.

thats becuase google maps uses network to get intial fix.. change it to ms assisted not ms based which does the same thing

Thank you for the post Eugene, my gps is actually functional now, locked on very fast and is accurate. Donate link?

I posted the Files! Just Diff them.. It's not that hard honestly

Thanks for the patch eugene373 but unfortunately it seems to do nothing for my GPS. Still takes forever for sats to get into view and never locks in to more than 1.

Unfortunately this didn't work for me at all. I even re flashed to stock then applied the gps fix and for me the gps was worse then any other thing I have tried. I never got a satellite lock, used to at least get 1 and it put me at times on the other side of the street,the accuracy decreased greatly

[Q] Problem with GPS - never locks

Anyone else having problems using the GPS on this device? I've tried several different GPS apps and none are working. The problem is that is finds 2-3 satellites, but never gets locked.

1 - Download "GPS Status & Toolbox" (EclipSim) from market
2 - Enable Location from Settings in order to use A-GPS data.
3 - Enable Use GPS from Settings
4 - Run "GPS Status & Toolbox" and then go to "GPS Status & Toolbox" menu where you can clear A-GPS and then download newest A-GPS data.
If you can't get a fix after this, you might have faulty SW or HW

You could also try "GpsFix" from the Market.

i am having the same problem too

Hi,
I'm using Sygic Mobile Maps 10 8.2 and Google Maps (unlocked with navigation). Both work fine with GPS and fix is within 5 sec.
Yet to try my stereo Bluetooth headset, will try in a sec ...
Edit: Headset at work, will try tomorrow...

This phone is very good for gps navigation.
Google Maps Navigation, Sygic Mobile Maps 10, Copilot Live, Navigon and Igomyway are working fine. They give me a lock within a few seconds.
A few tips:
Under Settings - Location and Security:
- enable using wireless networks
- enable GPS-satellites
If you're using WiFi the fix will be faster then without.
Oh yes, and one more thing: don't forget to insert your SIM-card.

For me to get gps fix, i need to stand outdoor without any roof on top of me, this is so bad if I'm indoor and beside a window, i can see a few satellites but it just wont lock on.
Is this software problem? I don't wish that it is my hardware problem

I called LG, and got the recipe for fixing the gps.
Do a "hard factory reset"
Turn off phone
hold HOME and VOLUME DOWN and POWER until you see the android. Then wait.
Done. It now sees 10 satelittes indoors, and uses them all, as opposed to maybe seeing one, and never using any.

I tried to use gps.conf and supl method but no luck, the issue weren't there. My gps was a jerk, last week i spent 30minutes to fix the satellite while driving in town. Even standing under the sky, the fastest I am able to fix is 200seconds, not to mention there are many times they wont even fix.
But my problem was stopped once i changed from stock to other rom. so I guess there is something else wrong in the stock rom, as the other roms are able to perform well even without gps.conf. (around 20-30 sec fix time).
So I guess only when your gps is able to lock satellite, gps.conf will help to speed it up. At least that's what happen to me

Best way to improve GPS?

Hello, I'm a recent owner of a SGS, and like many others, GPS is somewhat of an issue to me. However, reading around, there are a lot of fixes and solutions, and I want to know what people generally recommend to do on latest stock firmware to increase its accuracy?
Thanks!

I know it's a dumb name, but give "GPS AIDS" a try from the market. It was primarily made for SGS users. Try the free version first if still available...
Sent from my MB860 using xda premium

stock jvt gps is really good in comparison to out-of-box performance, and a lot better than wife's htc desire running on cm7.1. I get 10+ satellite lock in a few seconds, with a 10m accuracy. honestly, I don't need anything more than that (more often than not, I DO know where I am...) . Just make sure gps.conf file points to your region.
I tried recently a couple of these "fixes" ($omator, pfittech) but reverted back to stock files. I did not find any significant improvement, but of course you can give it a try, maybe in your region things are different

Well, thing is I don't know if GPS is working or not for me. In Google Maps the most accurate I can get is 30 meters, is that using cell triangulation or GPS?

Apparently 30 meters is not GPS from what I've been reading around. Guess that means I haven't used it at all.

Try GPS AIDS.
My GPS never worked before, I tried GPS AIDS and it gave me surprising results .

How to do GPS Fix
http://www.hdtechvideo.com/?p=43

Ever since I flashed to JVR stock, my GPS has been locking on the satellites like a charm. I'm not sure if the credit goes to the new JVR or higher firmware, but definitely give that a try if you're still on some of the older Gingerbread firmwares.

GPS AIDS doesn't seem to improve that much, still usually on 30m, rarely at 10m, not really accurate.

I really need help with this, thanks in advance!

[FIX] GPS Fixes

Hi,
So I've noticed alot of people have problems with their GPS from time to time on these forums so I've decided to collate any and all fixes into one place. Here they are:
NOTE: I'm not responsible for any harm done to your phone. These suggestions are tried at your own risk. These steps can be taken in any order you want and a reboot is recommended after you try each step.
First thing you can do to get accurate fixes is to go to the Location settings on your phone. Tick the boxes next to 'GPS Satellites' and 'Google's location service' (Press agree when the prompt comes up). Also click 'GPS Source' and make sure 'Use Internal GPS' is selected.
Click to expand...
Click to collapse
Second thing you can do is download the 'GPS Status & Toolbox' app from the market. Once installed go into the app and hit Menu and then select Tools. From the popup menu select Manage A-GPS state. Select Reset and then Download. Reboot and see if you can get a fix now.
Click to expand...
Click to collapse
It is recommended you have a Nandroid backup before trying anything below.
Third thing you can do is download this GPS Fix made for the Legend (From Kot_Ik’s CM7.2 unofficial thread). Put it on your SDCard and reboot to recovery and flash it.
Click to expand...
Click to collapse
Fourth thing you can do is flash a new radio in recovery. Get one from here. Try the bottom 2 first before trying the top one. This doesn't seem to be supported in the latest versions of CWM so you should load an earlier fake flash zip file. Go here for the recovery and instructions (Thanks ranger4740)

Last thing I can think of is to change ROM's and see if that fixes anything.

It is a config file parsed per line. This means that there shouldn't be any new line characters for lines that the system has to interpret as one.
It's perfectly OK to use a local NTP-server, by the way. It just doesn't fix problems at all. The short differences in the time the packets take to be sent and received are eliminated by the NTP protocol anyway.
Most so called "GPS fixes" are bogus at best (using the newest baseband firmware is something I'd recommend though).

Ok, what I have noticed so far using legend. Don't mess with gps.conf using other custom gps.conf I've use some before (instant lock) and its bogus as Ali ba put it.
Just use faster fix is enough.
OK, now currently I'm on zuebes cm9 and GPS works but getting it to lock is something else. And I love my waze.
I'll get in my car and start waze. Wait for a minutes or 2 than start moving. Lock or no lock, just start moving. Don't drive so fast but stay constant either 40kmh or 60kmh will do just fine. My lock usually happens when I stop at a junction or a traffic light or slow down before a corner.
Then when you lock for the first time. You can combo for the next trip as long as you on your waze at the same spot before leaving. It's instant lock for some cases but need to start over if it does not lock. Assume you use waze.
But if GPS is important. Use stock based rom and ogo2s rom also have good GPS if I remember well... I think its something about HTC didn't release GPS source that we ended up like this.

Alright I've changed the post and removed the step about changing the gps.conf.

I'm sorry that it broke your device, but I can't do more than pointing out that these files are invalid.

So I point out that these files are not only useless (as most GPS fix instructions are) but also broken and invalid and what do I get? Some random guy jumping at me telling me how stupid I am because GPS coincidentally started working on his device after doing some useless things?
You know, that's not even something I have to do (as if I was getting paid for support), I'm doing it because I'm basically a nice guy.
And then you, another random "I know how to register an account so let's attack people"-user, shows up. Thanks, you're welcome. Oh, I was right, by the way. The files are broken. The fixes don't work.

Ok, what I have noticed so far using legend. Don't mess with gps.conf using other custom gps.conf I've use some before (instant lock) and its bogus as Ali ba put it.

That's right. There's a bug somewhere in the GPS module but we never got any sources so we don't really know how to work around it. The GPS module on the Legend doesn't have public sources so we hacked together some code from different versions. It works pretty well - once it starts working.
I sometimes can't get a GPS fix either when I started the device with GPS turned off or after toggling GPS a few times. Yeah, it is broken and I am aware of that.
The only "solutions" that really work are rebooting your device with GPS and mobile internet connection turned on. This lets it download AGPS data, inject the current time into the module and you'll get a fix within 20 seconds.
Using the latest radio (=baseband firmware) for your region has been reported to kickstart GPS as well. That's the only fix I can confirm, everything else is shenanigans and you should get your money back .

By quoting me you are implying I'm some one that only knows how to register and start attacking people, how did I attack you, most people here know your the master who gave us all cm for our legend which is wonderful, and I simply asked you as you are the expert to explain how? Then you come back with your B.S answer attacking me, for no real good reason Instead of explaining humanly the answer, you also imply I attack people, when all I do here is try and learn to do stuff, and help others when I can.
Any way best you add me to your ignore list then you won't have to see me attack and abuse every one on xda developers ever again! Hey better still report me to the mods and get me permanently band from xda forums if you've seriously got some evidence of constaintly attacking members.

Calm down. Nobody attacks people. I appreciate your work concerning the Legend port - and stated that several times.
Not giving an answer is ok - as you said, no paid support.
However, I can't agree on statements like ...

ugh! this is unnecessary fighting, ali ba might just misunderstood ranger4740 questions, cos it sound corny at first look but if you read it again it's just a genuine question.
about gps fixes, we should trust the expert, yes this won't work as ali ba said there's some bugs in gps module. This fixes might work on other devices but I wonder if it does anything for our Ancient Legend

Agree. Back on topic

...So I am using Zeubea's ICS ROM (BETA3) and my GPS isn't working.
I have refreshed the AGPS-data and flashed the newest (?) radio (7.13.35.05).
In what way is the radio dependent on my geographical location? I live in Sweden, am I using the correct radio?
I get no lock, but I get accuracy of roughly 2km. How is this?
Also, I'm searching for an app to see how many satelites I am connected to, havn't found one yet.
Any help in this would be greatly appreciated - thank you in advance ♥

try using mobile data to get a good starting point (google's location service), also check gps source in location settings, and then try to get the precise location somewhere with a good view of sky....every next time it'll be faster, (you can even disable google's location service if you don't like it being turned on,it should still work faster than the first time after flashing)
edit: i just tried what i wrote above and got fix in no time,even from my room,using zeubeas cm9 beta3 freshly flashed... so, enable mobile data for a brief time until you get gps lock then you can disable it if you wish
