i9000m GPS: Working theory - Galaxy S I9000 General

So we all have issues with the i9000m and GPS (Or many of us do).
After I got my replacement hardware with a Dec date on it and when it was running 2.1 and was using whatever the version of Google maps was out at that time (Dec 24th), my phone was getting GPS lock really snappily.
After updating to JL2 of 2.2, it became unpredictable but when it was working, it was VERY fast. Two weeks later, my friend got his back and they had only replaced his mobo but he was unable to get a GPS lock in Google Maps or any Google app that used GPS.
Today, on break, after I had fiddled with my phone some this week, we tested what I was thinking of, that being: Google Maps or something with how it and 2.2 interacts is broke on our phones.
Here is what I did that was also tested and is doing the exact same thing on mine and my friends phone:
Install the Tricorder app
Reboot the phone (Either battery pull or power switch, same result)
Try to get a GPS lock in Google Maps (Our phones would time out to power save before it would get a lock)
Start Tricorder, go to the GPS/Compass section and wait for the satellite bars to turn blue
Exit Tricorder and then start Google Maps or any other Google app, the GPS lock will occur in less than 10 seconds every time
If anyone else could test this on the newer hardware or on a phone that had its mobo replaced, it would be nice to see if this is happening on more than these two phones.
And note that once I started and exited from Tricorder after it locked, all GPS apps now locked super fast.
Both our phones are running official JL2 2.2 with no rooting or whatnot.
Thanks,
Jason.

It is well known that you sometimes need more than 30 seconds (default screen off delay) to get a lock.
But if you start an application that can run in the background such as google navigation or my tracks (recording on), your GPS won't shut down when the screen turn off and you will finally get a fix if you wait long enough.
It is also well known that once you get a fix, if you loose it (by turning off your GPS app) you can get it back really quickly.
You didn't find anything special. Just leave google maps open (by pressing on the screen at least once every 30 seconds) and you will get a lock just as fast as with your tricorder app. There is no magic. You only need to leave your GPS on for long enough.
From my experience, I sometimes waited 2-3 minutes with JL2. But I don't care, as long as the GPS is accurate.

I have exactly the same lock on with Eclair > JPY > JPX > instant to about 30 seconds .
This is about the hundredth supposed fix posted .

And how is waiting in Tricorder for a GPS fix instead of Google maps a solution?

Exactly zorxd..

ok, so what if since either (can't say for sure cuz don't use gps much at all) rooting, or flashing speedmod k13e, when i pull down the tool screen and click on gps to turn it green, the gps icon does not appear at the top of the screen - i don't think it's on at all. apps like maps, gps navigator etc that use the gps don't work.
what's that about?

GPS after the update

I think I've updated my phone with something called Kies mini... I am trying to check my location with the gps but it aint even close to where I live!!!
Everyone talks about how satellites has their gps locked on to but I have no idea how to see that... with gps test.
HELP PLEASE! It has been always showing the same location doesnt matter which city I'm on! (before the update too)...
I think once I have tested this gps fix that was around, but then I went back to normal settings (i guess)... cause it didnt work
Now it it says that I have ECLAIR.UVJI6
I am new to all this
Search the market for an app called "GPS Test". It will show you all of the information you're looking for.
Well, I'm still having GPS difficulties with the newest update (Running Bionix 1.9).
ECLAIR.UVJI6 is the newest update, so don't worry about that.

I have GPS Test and GPS Status... The first one doest even move at all when I start the application and the second one on the bottom show it seems that is loading something forever. Where do I see the sats? Have no idea. From the second one I will guess that it could be that part that says "fix/sats" and right now is saying 0/2.
My goodness... The damn gps would so useful to stop loosing myself on the German streets
Nothing that I can do to fix it? Is there any news about if this is the last official fix for the gps?
My GPS was working great when I first odin JI6, now all of the sudden it just stop working, I try to odin it back to JI6 again and it still doesnt work so well.
I'm testing the GPS out right now. I've had the phone since wednesday, tried google maps and it's never been able to get my location. I just installed JI6 today and ran GPS test for the first time. I got 0 satellites for a couple of runs until my 3rd try where it eventually got up to 10.
Even though I get locks on GPS test, google maps/navi still can't pick up my location so it's useless =\
In my specific case, I found that the JI6 GPS update did not perform much better than the original version. Yes it was better, but certainly not as good as the JI2 update. So, I've applied the JI2 update and things seem to work much better.
Also, I've found that turning off wifi when making the initial GPS lock really helps reduce the amount of time needed to initially lock.
Good luck!
^ second that. Try to turn off wifi.

FYI - Ive had good luck changing to MS Based:
From link-
""In MS-Based mode, the network provides the satellite information to the device, based on a rough estimate of where the device is located, and the device acquires the GPS signals from the satellites and calculates its location. After the initial fix, the device operates like an autonomous GPS receiver, until the satellite information must be refreshed, at which time the device goes back to the network to update the satellite information. MS-Based mode is appropriate for applications that require the device location to be updated rapidly, such as a navigation application. Can the GPS work in autonomous mode? No, the GPS receiver requires the assistance of the network elements to acquire its initial location fix.""
i flashed bionix 1.9 and had more problems with gps than when i was running 1.5. atleast before it was sort of accurate... and found a couple sats after 2-3 minutes. but iwth 1.9... nothing and not even the correct side of the street (showed me east while i was way west). then i found someone who had a gps fix based on j12 and it was in zip so... i mounted that to me SD and reinstalled using clockwork recovery... now within seconds i get gps ... extremely accurate... AND... lock on to most of the satelites that are available. i love it!
Right, so here are my thoughts and experiences while using the new JI6 update:
1) Way more accurate than the previous couple of builds that I have tried. When the GPS does lock, it usually locks onto 10/12 birds and finds my location within 5-6 meters. Not bad! Definitely not as good as when I had GPS working via one of Eugene's Franken-Twiz ROMs (between 2-3 meters), but definitely good enough for daily navigation.
2) The fix for damn sure didn't fix any of the satellite aquisition problems that our phones have been experiencing. Typically for me it will aquire satellites right off the bat about 50% of the time. Other times I'm left waiting 20+ minutes for it to get a lock.
3) Solution I have found to get a quick fix. Type in *#3214789650# (for the new JI6 update) and delete the GPS Data cache. I think it's the last button on the list. After the cache is cleared, use the top button on the list to perform a location test. I've seen this take anywhere from 30 seconds up to 2 minutes... sometimes a bit longer if I am in an area with poor signal coverage. Once I have aquired a successful lock on multiple birds, I simply back out of the application and am good to go. If I leave GPS constantly on, I have found that my phone will maintain the lock almost indef. If I turn the feature off during the day to conserve battery life I have found that it will usually aquire a lock within 30 secs or so of me turning GPS back on IF I am still in the area where I turned the feature off. If I drive to an area an hour or so away from where I turned it off, I usually have to repeat the above process to get a quick fix.
I've tried every iteration of option combinations from the lbltest menu, and have mostly been greeted by similar results, with no one option particularly speeding up the process. Based off of this I am assuming the issue probably lies with the caching of stale data on our phones, and it's inability to purge this data on it's own.
The one thing I haven't tried yet is the JI2 fix mentioned above. I might give this a whirl and see how it works!
BTW, I'm an expat working in Europe, so this might also be the cause of my slow lock times... however every other GPS I own works magnificently over here.

That's the first "fix" for the gps? I tried once but it didnt work.
I have tried pretty much all the "fixes" I can think of and this is what I have found. No matter the source (root mods, Bionix, J12/J14/J15/J16-leaked and OTA), changing from 'standalone' to msbased helps tremendously. Also using the google server and port is much much better for faster locks and maintaining lock even if you are not in clear view of the sky (tree, buildings etc will affect you lock). I willl say the stock JFD with the msbased and google server and port was better than just about all the other ones I have tried with the stock standalone and spirint server.
IMO The OTA J16 is the fastest and most accurate (less than 10 feet everytime, less than 30sec fix everytime) that I have tried, but even that required me to use the google server and port, and also switch to msbased.

Gonna try this out! cheers
finds sats but won't lock on...
I'm still having GPS problems post-update. I've never installed any custom ROMs or any custom GPS fixes other than some tweaking in the LbsTestMode menus, which I have since reverted to the default.
In the LbsTest or the GPS Test app I get the same results: the phone always finds 10-12 satellites just fine (levels in the 20s) but it never locks onto my location. GPS Test will say "In View: 10" for 20 minutes but "In Use" always stays at 0.
Anybody have any ideas here? I was really hopeful that I'd finally have a functioning GPS after this update.

exact same issue. drive an hour away and the gps is hosed unless you clear it and start it again.
I am also overseas. I wonder if grabbing the GPS settings from I9000 would help? Does anyone have them or know where to find them?
EDIT: nevermind they are the same settings

I used the GPS for hours going between statelines with JI6, no problems requiring a signal when I closed out GPS.

the thing is... mine worked in the states with the stock JFD without any problem. flawless.
it stopped working when i got overseas. and hasn't worked well since. It really seems like it ONLY works well in the states. I mean I can get it to work if I clear the data all the time, reset the phone all the time, but it's not supposed to work like that. It should just find me when i open maps like any sound person would expect from the device. can anyone contend? is anyone having flawless GPS functionality outside the US?

I've rebooted at least 5 or 6 times, as well as clearing the GPS cache ("Delete GPS Data" in LbsTestMode) numerous times as well. Still never gets a location lock despite seeing 10-11 satellites.

[Q] GPS lock issues?

Anyone else having issues getting a GPS lock? I'm sitting inside a building but my Hero would always lock here, especially after resetting the AGPS data with GPS Status program. Tried that with the Shift, and still not getting a lock even after a minute. Not sure what else to try.
Typically I keep mine turned off, but I just turned mine on and went to Maps and it locks my location in.
mine took a little while to initialize (indoors) but it locked in within 30 seconds.
No issues here. Inside my GFs apartment it locks very quick and is probably about 5-10 feet off according to google maps. My moments GPS never locked or worked so I'm extremely happy with the GPS quality on this phone.
The first lock took around a minute to get. Now it gets a solid lock in just a few seconds, if that.
A little off. Not as bad as my gfs Samsung Instinct, but it does often have me a few hundred meters from my actual location.

GPS is spotty for me as well. GPS Status won't even get it working for me when it won't work.
When it does work it is not as accurate as my Heroc was. Hopefully this gets some love in any updates.
GPS is great for me. The only issue I've run into is that when I go from Maps to Navigation, my SD card gets mounted as read-only for some reason.
I know a couple of days ago I tried to use my Google Maps/GPS and it couldn't get a lock on me. It was like going crazy or something. However, it was snowing and kinda foggy so maybe that had something to do with it. It worked the next day though when the sky was clear.
No gps lock on my end either. Also tried the gps status clear....nothing so far
EDIT: just opened maps for about a minute or so and it locked finally. Closed maps then opened again, locked within seconds.
Bumping this thread: I have issues with getting a GPS lock. If I open Google Maps, I'll never get a lock (at least not before the phone goes to sleep - 60 seconds). I open up GPS test, which I downloaded from the market. It gets one satellite to lock right away. Sometimes two. Then it takes forever to get 3-4 more (at least 60 seconds). I can then go into google maps, and it will get a lock within 15-20 seconds. But if I let the phone go to sleep, and open up maps again, I don't get a lock, unless I do the GPS test. And sometimes that doesn't even work. I've done the GPS Clear thing, via the epst codes (##GPSCLRX#), and that doesn't seem to do anything. I'm running the MikShiftG 1.1 rom. I'm going to make a nandroid backup, and see if that happens on a stock 2.3.3 rooted rom.

DL30 and GPS

I still notice the gps still takes long to lock in. any suggestions?
Strange, Mines been locking on in no more that 45 seconds, Usually 10 seconds since DJ05...
DLO9 - using leaked 2.2 Rom
My GPS is taking much longer to lock also - i guess its the trade-off for getting 2.2.
The leak 2.2 rom run better than the other Roms I tried.
Sent from my SCH-I500 using XDA App
Odd, mine locks on better than any 2.1 rom and almost instantly.
Oddly enough, got worse on superclean 2.2. With DL09 and superclean (with help from gps status) i was locking within 10-15 seconds, now it takes upwards of 45s-1minute, if it locks at all. A little disappointing, but nothing to make me dump 2.2. Crossing my fingers that it'll get better....
My experience with all 2.2 ROMs so far has been that GPS either locks near-instantly (<15s) or absolutely will not lock at all. It seems to be about a 50/50 crapshoot. If it doesn't work, turning GPS off, waiting a few moments, and then turning it back on and trying again *usually* gets it working.
Granted I haven't tried since jt released the updated recovery, so I'll have to check a few more times and report back.
Try flashing the DJ05 GPS fix that was tested on people with Dl01?
I've long given up on the GPS, I just use my Iphone 3GS that without data connection still locks on really fast.
I tried DL09 when first going to Superclean 1.0. The GPS would lose the signal then regain it. This happened about three times during a hour long route.
Flashed DJ05 last night and tried the GPS again this morning and not once did it lose the signal driving into work.
My gps doesn't WORK AT ALL with DL30 superclean 1.0.
Mine locks in 10 seconds or less running DL30 SuperClean 1.0 with DJ05 radio.
I have been having a problem with GPS on DL30/DL09 also. Here is how I got it to lock today in less than 10 seconds.
1. Download GPS Status from the market.
2. Run GPS Status and let it download the AGPS data.
3. Go into settings>GPS & Sensors>Auto-download AGPS data and set it to never.
4. Close GPS Status and reboot phone with GPS turned on.
5. Once booted, run GPS Status and hopefully you will get almost insta-lock.
6. Open Maps or Navigation and you should be good to go.
Next time you try GPS and it doesnt lock, go back into GPS Status>options>tools>download and manually download the AGPS data then reboot.
Its a pain but its the only way I know of thus far to get "insta-lock" after going Froyo on my phone. I dont use my GPS all that often so this method isnt a big deal for me, but if I relied on GPS daily, I would seriously consider buying a different phone at this point. That or try and get a refurb that has a working GPS like some people here seem to have.

Didn't work for me. installed DJ05 and still nothing :[
Ive had some weird experience with GPS. DI01 My gps was garbage. like 2 mile blue sphere. DJ05 my gps was pretty good... locked accurately but took about 2 minutes. Borked my phone trying to edit some stuff... redid DJ05... GPS didnt work again... did DL09... GPS still didnt work... redid DL09... GPS worked pretty well again... DID DL30... GPS locks nearly instantly and almost perfectly.
It seems like every time I flash I have different results...even when sometimes I'm flashing the same roms from the same sources. I don't really get it... I'm almost in the same areas so it should be consistant.
I always clear all the caches and everything :\
Ive done many different gps tests and here is whats happening...if you try to turn gps on through the notification pulldown...it takes a while. If you turn gps on through settings...location and security...standalone gps...its instant. After turning gps on through settings, it will work from the pulldown every time instantly. Basically it needs to be turned on from settings for the 1st time after a reboot...then the pulldown will be instant. To test this, reboot phone with gps off, when it boots turn gps on from the pulldown...it wont lock...go to settings and turn it off then on...it will lock instantly. Like i said, it seems to need to be turned on through settings initially, then it works instantly any way you use it...hope i helped.
That's strange. I haven't had an issue locking on since DI01. I also love how fantastically loud the Nav directions are now. I agree that gps status can greatly accelerate the locking on process.

daym you!! lol. maybe it's time to go get a replacement?

Why does my GPS STILL not work?

Loving the phone and the community here, but I'm starting to get frustrated with this thing. Before DL09, I could never get a lock. After updating to it (manually, before it was an ota), my gps worked for the first time ever. However after switching to DL30 and subsequently EB01, I can no longer achieve a lock. I thought this fix was already taken care of? How come the newer radios aren't working on my phone?
I'm currently using the EB01 radio on Superclean 2.4
You turned on all of the GPS settings (Google, verizon, standalone) and cannot get a lock?
Im getting a lock on EB01 way faster than DL09.
I'm on super clean 2.2 and I have no issues with GPS. Have you considered that your phone's GPS may be faulty? I'd exchange it.
Sent from my SCH-I500 using XDA App
I leave the GPS on all the time. In most buildings it keeps the lock. I really hope that leaving it on makes it easier to live with.
Sent from my SCH-I500 using XDA App
In my foray into EB01, GPS was flawless... for a day. After that I couldn't get a lock to save my life, rebooting clearing stats etc.
The difference was four friends came in from out of town with GSM android phones. We all were having issues. It is like they were kryptonite.
Of course it is ridiculous to think that one GPS would mess up another since they are passive devices. I would advise taking this as weak entertainment or with a grain of salt. DL09 is back yup normal, usually 10 seconds sometimes two minutes for a lock.
In my opinion, getting stable froyo on these units won't be so easy, and I hope we get a few timely releases until they get it right. If EB01 does go OTA, I am screaming bloody murder the moment my clock goes out of synch.
Swyped w/ XDA App. When in doubt, mumble.
try turning on your wifi network (even if your not on a wifi network) this gives you a pretty good position.

For positioning, I just use the cell towers. That's fine. Its for turn-by-turn directions where I really want the GPS lock.
After 48 hours or so of uptime my GPS is definitely not as quick to fix as it was under DL09. I'm sitting in my favorite armchair looking at a fix with three satellites whereas I used to get a fix with 7 or 8 and an accuracy of 8 feet. After a reboot my fix time drops to about 15 seconds and I get a lock on 8 satellites.
these have been my experiences with Super Clean 2.x (voodoo and nonvoodoo):
- sometimes turning the GPS off from notification window and back on again will do the trick
- sometimes when the above doesn't work, turning it off and then back on again from within settings (where you need to click "agree") will be more effective. In this case I've even noticed a difference between doing this by going directly into settings vs. letting Google Nav tell me that GPS is disabled, and agreeing to let it take me to the location settings.
- bizarrely, sometimes opening "GPS Test" app (market, free) identifies satellites more immediately than Google Navigation. Then after GPS Test can see them, I go back into Google Nav and it will see the satellites right away.
- if all else fails rebooting the phone has always done it (and then doing the same dance described above)
Don't get me wrong I wish it were more stable/reliable but the above seems to do the trick. When it locks at all - it locks right away. I have just forced myself to make sure that the GPS is working before leaving the driveway, or else I run the risk of being frustrated when I need to make a snap decision to go somewhere that requires navigational aid. For me it's almost as if the Android OS isn't properly wrapping its arms around the GPS hardware than an issue of the apps locking a fix.
Last night I almost missed a flight and even went as far as to say "I really need to start bringing my old GPS around with me again". I really hope to avoid this.

[Q] I5800L GPS in Froyo roms

I have a I5800L (from vivo brazil), and when im using the stock eclair rom (VIJG7) my GPS gets a lock in less than 20 seconds. But when i update to ANY froyo rom (Kyrillos, InDroid, XXJPM, XXJPN, XXJPQ ... ) my GPS takes more than 15 minutes to get a lock. I've tried every GPS fix i found here, but it still doesn't work. Do anyone have any ideas?
When I had purchased my phone, I never used to get a lock.
Try this...
1. Look through the forum and you will find ways to configure the ntp server.(gps.conf) file.
2. Get this app called "GPS Status" and "GPS Optimization by octy".
3. Start your GPS using the GPS Optimization and then open GPS Status.
4. Go to tools--> Manage GPS-->Reset
5. Download assistance data.
Initially it will take some time to lock, but as u do this more and more, you wouldn't ever require GPS Status.
Just turn on gps with octy and you will get a lock soon.
Have patience.
When i got my galaxy 3 in Pakistan but set was purchased in UK i got the same problem..sometimes i got fix in 5minutes and sometimes when i am in a car i literally try for hour but i cant get lock...
Then i got through one thread sorry i don't know the exact name having lot of coding to fix gps..in this thread i see simple thing..
simple use this code *#*#1472365#*#*
it will open the gps setup2 do nothing and come back to your app it will caught 9 10 satellites in few seconds..
hope this will fix your problem..i am using this trick perfectly on my stock rom use offline maps in maverick..
Same problem here froyo messed up GPS.
Phone finds satellites fairly quickly (GPS status) but to get a fix on them takes forever if a fix at all comes.
Did not have this problem before froyo.
Well I did have some GPS problems but now it has become impossible.
Tried all apps I think, GPS boost, GPS aids.
I think I have the weird of all. GPS doesn't work at all. Network does. When I open Maps aftera long gap with wireless network on, it finds my location within 5 seconds, but wait ................. it jumps into completely different location instantly. originally I am from kolkata, it shows the same at first second and just jumps into JAPAN :O:O .. yesterday got the same thing but in different location, but it was within India atleast .. .. it was @ Roorkee, india. Lost all hopes.......... :|
