Finally a GPS fix for SGS

after applying the attached zip through CWM the GPS is finally working!
instructions:
1. apply the fix through CWM
2. in LBSTestMode:
a. verify all values in the application test are default
b. in the SUPL put supl.google.com and change the port to 7276 with no secure socket
c. wipe GPS data
3. after the first fix (~3 minutes) you will get a fix instantly almost in any condition at any time
the fix was validated on 2 different vibrants with GPS issues
goodluck

He got this from the i9000 forums. I've personally used this, and it helps with the gps dramatically.

This is an old, well known pre-JI6 fix. DO NOT APPLY! This also NOT development related, try the General forum next time.

Hi all,
you can say what you want about this fix however, both I and BobLeponge23 have vibrant's phones with GPS issues.
we have tried all possible fixes:
JI6, JI2, JK2, JK6, samsung restore app, changing all the settings through LBSTestMode
nothing worked until we tried this fix.
The change is instant.
we have now a working GPS under:
the new axura 2.1 (JK6) and Obsidian_V5_beta (with modem JI6 installed).

Ok. Won't argue with that. Whatever works for ya!

Do you have "Use wireless network" unchecked? And WiFi off? With only "Use GPS Sat" checked? Cause that is the only way to see if your GPS is really fixed.

in LBS Test mode you wont get fix just with wireless networkor or WiFi.
in general when the GPS icon is flushing you dont have a satt. fix although
you might get general fix from the wireless network.

That's not a good test for phone GPS units. The phone's GPS uses network location to help get a faster fix. Apps like GPSTest, GPSStatus, and LBSTestMode won't report a GPS fix with only a network/wifi fix, so I don't understand the obsession with this sort of a test. All it will do is slow down your GPS locks.
Disabling wifi does make a difference on newer firmware (worked on JFD, but JI6 and up broke it). With wifi connected, the phone doesn't download the GPS data properly, so it acts like a standalone GPS and will take a long time to get the needed data from the GPS sats.
The GPS chips in our phones are NOT designed to get fast locks without assist data. Even the ones that are, sometimes take a while for the accuracy to really get good because of this data. That's why you should have a data plan for best results. The GPS needs data to calculate your position. It can get the data from the sat network, but that's SLOW. Getting it over the internet is many times faster, even over GPRS. That's one reason why it's irritating that wifi doesn't work with it. Those without data plans are basically screwed. GPSStatus seems to be able to get it over wifi, so you can try that. The data should be good for up to 24 hours.
I have no idea what this fix does, and I won't be installing it as I'm satisfied with the GPS performance post JI6 with my phone. Even with JFD, it worked fine once I set the supl settings up.

they are sharing a fix.

Honestly, it worked for me on JK6.....

If this is working for folks where flashing Axura 2.1 didn't then, that's all that matters. Go for it. However as I'm running Axura 2.1, I have no need of this.
I just don't want people thinking this is the ultimate fix and breaking their phones trying it. I've seen it happen with simpler fixes.

I was using a jk2 rom also, and GPS would work at times, even in a large Metro area. i flashed this, and now I even get GPS locks inside of buildings where it would never lock before. I am happy. Indoors, it gets a lock in about 10 - 12 seconds, outdoors about 5 or less.

I don't understand how it can work, it uses jupiter.xml subsystem that TMO US Vibrant lacks

well fellas, i have so much dragons in the vibrant already i figure what could possably go wrong now lol. Running nero beta 3 and it actually works,got an instant lock on precisely where i was,dident had that before with all the other fixes,couldent believe it but yep works. Thanks for this fix

Didn't make a difference for me. Since JK2 ive always got a fix in under a minute. With this installed it was over a minute but under two minutes. I'll keep it for a day to side if anything changes and report back.
I'm running a vanilla SxE4.1 with super io kernel.

Serious GPS issue..

I have tried every single GPS fix out there on this forum but my GPS is still not working... inside a building GPS test says that there is no satellite in view.... outside I see about 6 and locks to about 3 or 4....
(But it takes like 5min to lock)...
Is there something wrong with my phone? And btw I'm running cognition rom and I'm rooted.(if this has anything to do with it...

Try the Darky port that uses Da_G's fix. Best GPS experience I've had so far with this phone and the only thing that has realistically improved performance.

my best gps performance has come from two roms
Chronus and Doc's newest rom.
Did you change any supl settings?
For me the supl.google.com settings never worked as well as leaving it @ www.spirent-lcs.com
build = 1007.

I have had great gps since i switched to assonance, latest version of axura worked for me as well, you may want to give them a try, or try their gps settings and modem over cognition.
If that doesn't work you may want to scratch/erase the white contacts of the cover as one post said to maybe increase its signal.

I would return it..you should be able to lock faster than 5 mins and see more than 6 satellites

I agree with fldude... my first one wouldn't see anything. My second one works as well as anyone's. Exchange it.

I really can't return it cause I didn't buy this phone....
So I'm gonna try all the roms... thanks for the info guys
Sent from my SAMSUNG-SGH-I897 using XDA App

Most of the newer ROM's have GPS fixes built into them
I'm running Assonance's latest build and although it's not perfect - I usually get 8-10 sats in under 15 seconds to lock-on.

I just started using the latest assonance and it has great gps thanks.

i agree mostly that that using the google server didn't help me at all and the roms you mention are quite good. but i have the bug where the daemon crashes on chronus, but cronus has the ability to lock very very fast on my phone, i have had great luck with captivate builds in general. da_g's files fix the daemon crashing mostly but are not considered a fix. there is still an underlying issue that causes eratic behavior in certain situation. da_g has yet to pin it down but it may be an interference issue.
OP you may have a poor contact at the antenna, some vibrant users were cleaning the contacts for the antenna, there are many antennas and im not sure which is for gps.
also you may want to try with/without backplate, and clean the contacts on that. some users have posted numbers showing marginally better signal without the backplate.
also i have yet to do real testing but anecdotally the old jm9 libraries seem to behave less badly. it still jumps the position around in some situations but it just seems like it jumps less, i will do a mytracks comparison soon. but for the issue the op is having it seems to me that i get faster locks with the newer files, particularly from jj4.
lastly the modem has a great effect on the gps signal. for ability to lock jl3 seems the fastest. but to be honest i think the phone didnt jump the position around as much on jj4 or ji6 which give up hsupa and should be used with the a captivate rom. jk3 and jk4 were also good maybe better with the position jumping thing than jl3.
EDIT: one last thing is to try the gps restore app. i know it says it only resets lbs test mode settings but it also clears "something" that has helped with a bug causing the daemon to crash on my phone(it doesnt crash on every phone like it did on mine) the only other thing that i tried that was able to "fix" that bug was to do a factory reset. clearing gps data never helped. so the error seems to be in data somewhere but is not cleared when you clear gps data in lbs test mode. the samsung app also did not restore my lbs settings to factory so the ad may be mis-informed. i think of it as a easier way to clear gps data which at times yeilds better result, it is not a fix. your experience may vary.

[Q] GPS...

I recently swapped my original Captivate for a new one because it had random shutdown issues. However, the old one had no problems getting a quick and accurate GPS lock with various ROM's and modem versions.
This new Captivate will NOT lock at all. Both stock and running custom ROM's, JL2, JL3, JK4, JPY, JM9, etc. I've double checked my GPS Fix settings, cleared GPS data, reset and reflashed multiple times, but my GPS does absolutely nothing. Running LbsTestMode, all that happens is the GPS icon in the notification bar useless flashes, but nothing appears in the test menu, it doesn't appear to be searching for satellites or anything.
From this information, does this sound like a hardware issue? Getting my Captivate exchanged the first time was a big hassle, and my parents seem very unwilling to do it again (as far as they're concerned, if it can make calls, there's nothing wrong with it).

In the LBS Test Mode make sure that the Server is set to supl.google.com and port is 7276, And then delete GPS data.. You should get a lock-on pretty quick

Already did that. The problem isn't exactly getting a lock...LBS Test Mode doesn't even show the GPS trying to get one. On my previous Captivate, if I was indoors or somewhere where a lock was difficult, it would still show the GPS hardware scanning for satellites. This new phone doesn't even do that.

Hmm.. try the Phoenix 3.0 with the Kernel and Modem that comes with it.. and then try GPS.. Axura and Phoenix ROMs are known for it's awesome GPS

Eh...nevermind I guess. This phone is only 2 days old and it has a defective USB port, so I'm returning it. Starting to feel less inclined to get another Captivate, even though it's an awesome phone...when it works.

I swear they do this to discourage exchanging phones. That sucks dude

[Q] GPS not working

Help please! GPS has stopped working suddenly on my SGS. I had an overclocked (1120 Mhz) SGS running Darky's ROM 9.3. Everything was okay till two days back.
I guess it maybe because of too much apps on my phone or the fact that my kid had dropped it once or twice. There were no problems initially. Then phone had rebooting issues.
I've since formatted it yesterday night and it seems to be okay in terms of rebooting and stuff. I then noticed today that GPS was unable to pinpoint me on GMaps. All I saw in Google Maps was "Your current location is temporarily unavailable"
I thought it maybe bad 3G signal and I tried it outside --> No detection. Back at home I tried with Wi-fi having ticked all 3 options in Settings --> My Location. Still no use.
I then decided to run *#*#1472365#*#* but nothing comes up --> NOTHING! I tried with the tool "SGS Info" (GPS Test/ Settings) and ended up with the same result. Other options in "SGS Info" seem to work fine.
Now I have a feeling my GPS may be malfunctioning or worse broken for good. Can someone clarify this? It would also help if you have suggestions in terms of any other tools, so that I can check the GPS unit of my phone!

Could be hardware more likely the rom or software malfunction .
best would be flash stock rom via Odin and test if its hardware you stand a chance of warranty repair with stock rom .

^ Good advice. Stock ROM is always good to try, first, you may want to try what's working for me at the moment.
Download an app called GPS test. Try it in a few different areas of your house to get the best result, but see how many satellites you can pick up. Generally, I find I get a decent signal if I can lock 5 or more satellites. Gray means they are found, but not locked. They will be coloured when locked on. anything above 20 is generally a strong enough signal to provide a decent GPS signal.
I've found that keeping my GPS close to windows or "in view of the sky" actually helps my signal quite a bit, even if its just to lock the satellite, then I can bring it away from the window.
You may also want to read this thread, should neither of those help you.
The GPS on the Galaxy needs some TLC in order to get working properly, but with a little playing around you can find what works for you.

I went back to XXJPX - that's something that came in Dec 2010. Stock ROM from Europe I guess. But still the same issue. Thanks for the suggestion though!

I have tried putting a bit of pressure on the top portion of the unit. But no GPS detected Looks like I got to try to get it repaired. Now that I am on stock ROM I guess it should be fine in terms of warranty. Thanks for the links and your suggestions.

Well, know what; I tried again in a more open area (importantly in a not so remote area) and it works - at least in GMaps! I am still on XXJPX, so I am unable to say whether something went bad in Darky's ROM, but I am happy nonetheless!

I reverted to stock and it didn't work as well, tell me if it helps you please

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...

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
http://forum.xda-developers.com/showthread.php?t=953630

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.
