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

No offense, but who are you? I'm not one to flash random zips I download off the internet.

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

JK2 and JK6 now use the Jupiter xml

is this working in eugenes ginger clone?

It worked for me! Why don't you just test the files and see why it works instead of whining?

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.

[Q] GPS fix. ##GPSCLRX# not working

I've encountered a problem with my GPS while running AOSP Roms. (In my case MIUI) The problem is that after a while of using the GPS, I'll wake the phone up and the GPS will get my location, but then stop working/updating location.
I've tried flashing the stock Sense ROM, and doing the ##GPSCLRX# trick without success. The method simply doesn't seem to work, or have any reaction whatsoever. I can't get the text box to open where you enter the MSL. Has anyone had any success doing this method? If so, which ROM did you use? Was there any special mojo you had to do?
I've also in desperation tried installing various EVO GPS drivers, with no effect.

Also I tried reformatting my SD card, fresh install. Problem continues. Apparently I'm the only one with this funky problem?

Perhaps THIS can help, it improved my gps a lot. After that i get a fix i a few seconds ;-)
The standard gps.config is based on a generall one that works for all countries. If you follow the fix and edit your gps.config to your contry, the gps fix gets much faster.

I did this little trick, and I noticed it changed the way my GPS behaved at first, but I'm afraid it didn't work to solve this problem either. Thanks for the idea though.

GPS issues since root ?

Hello,
So, as the title tells, i've got some GPS issues since i'm using custom rom (both TW and AOSP ).
Nearly each time, it takes up to 15 Minutes before the first lock is made. So the usage of Google maps or any "speed control" apps is quite impossible.
I tried GPS status app and let it download new AGPS data. But even when I am outside it finds only 1/2 satellites without fix.
I think i'm gonna reverse to a Stock ROM tonight in order to test if it's really rooting problem.
Anybody has an other idea ?
Thanks,

It's closed now .
It was an hardware problem.

[Q] cm10 gps problem

Hello, i am using 20121014 nigthly cm10 from here http://forum.xda-developers.com/showthread.php?t=1778526
It seems for me that gps works kinda bad since my last installed cm 9 or cm 10, i dont remember..
Any advices how to fix it ? It fixes realy slowly and not accuracy..

Try hardware fix(search forum for this) and try fasterfix from market,should work..

It seems that I'm not the only one. I'm quite sure that something's definitely off in CM10 (others reported the same for SGS3, I don't know whether it's relevant or not...). Okay it's great that there's a hardware fix which should make the GPS perform better but still, it's not the primary problem. With CM9 I had a GPS fix in max. 20 seconds, now I can't get a stable one in 20 minutes. (Yeah, I've also tried FasterFix by the way.)

My gps works just fine on CM10, however, for some reason I sometimes have to have internet access when activating my gps for it to lock on satellites, I suppose it's because it updates gps info from the ntp server or something...
The difference is a weak connection to one satellite, and near-instant connection to 10-15 of them.
(tested with LBSTestMode)
I've also changed the server in gps.conf to NTP_SERVER=no.pool.ntp.org as that's my country specific server (norway).

Theres a really good app to configure your gps to right country. Hope it helps.

Thanks, already tried to use it for the country I'm in at the moment. (Yes, my GPS just broke down abroad, as my luck have it... )

gt-p1000 gps problems

hi all,
I was just wondering if I was the only one with gps troubles.
I tried stock rom, overcome, ics miui, jb aokp, but rarely got satellites detected.
I once got some connexions while using tomtom but about 20 minutes (discontinued) on a 2 hours trip.
with some test apps I got 3 feeble satellites signals.
Does someone else had so much trouble ?
(I trying some gps fixes I found but just wanted to know if I was the only one)
thanks

you are not the only one

No you are not.
Did you GPS work at all?
Mine did and then stopped.. here is what I did before it stopped.
I rooted it with ODIN (ages ago)
for ICS I followed the widely available instructions to get ICS (How to install Stable ICS 4.0.4 on Galaxy TAB P1000 [CyanogenMod 9 Stable]) and everything worked well. Needed a different camera app but the GPS worked reliable and FAST.
When JB was available I used the ROM Based on Jelly Bean 4.1.2 Platform. This is the official CyanogenMod 10 Nightly but had issues with Gapps and did not have time back then (xmas time) so just restored my nandroid backup. And to be honest I have no idea if the GPS worked after that. I think I used the iPhone more for GPS stuff until March.
Fact was it did not get any satelite at all, only location is via WIFI.
My hypo was that I may have missed something or the nandroid backup / restore does not include all files.
To fix it I looked for a later ROM and used JB. I used the Android 4.2.1 CM10.1 for Samsung Galaxy Tab 7 P1000 [Filename: cm-10.1-20121229-EXPERIMENTAL-p1-cdesai.zip] and Google Apps [Filename: gapps-jb-20121130-signed.zip] and that rome is reported that GPS works (but remember it did not work before i used this rom)
All went well and the rom works with all other features but did not GPS and I still have 0 satelites with either GPS Test or GPS Fix.
That is when I found your post.
I had a good dig around XDS and well GPS issues are plentiful, but not quite like the one you or I experience.
It seems that you at least get "some" satelites which is an improvement over none.
re-stocking did not solve it for you so I may save myself the trouble.
that said, my only thought is the GPS module packed in and that is why I get not a single satelite...
did you get anywhere?
TIA

hi there,
for my part, I bought this used tab some month ago. I didn't really liked it in gb, so almost immediatly tried to root it, changed recovery and rom, but never tested gps then.
I actually use miui ics rom and tried gps once. on a 2 hours long trip, sunny weather, nothing to disturb gps signal, I had 20mn of signal and not in a single straight connexion, but only just 1 or 2 mn from time to time.
I tried restock, but not bettre, even my chinese tab is more efficient. I'm still trying to understand and looking for answers but I nedd to restart my searches all over, too much things founds and now I'm quite lost.
The only thing I remember is that someone picked up gps files from his old samsung gsm and copied them on his GT as they had the same system.
I'll try to find that back, and maybe I'll try with my htc as they're all two on miui.
I'll send infos if I find something working

The same problem

Sorry for my english!
My GT-P1000 was to repair because it was unable to read the internal memory! After that I never tested the gps and rooted the tab with CM10.1 TWRP 20130802 Kernel 3.0.88 v1.35 (cm-10.1-20130802-UNOFFICIAL-p1)! I tried gps, but there is no gps signal and there are no satellites found!
Did ypu solved the problem?

no, still not solved it, I suspect some hardware problem like gps chip dead, gps antenna unplugged or broken, but as I had troubles with electronics thèses days, I will wait to open my GT

install apps like Faster GPS, GPS Fix or similar from Play
define your NTP Server and load XTRA data (table of current satellite position)
this will help you!
