My GPS has never worked well. I could *sometimes* get a lock on one or two satelites after a minute or so, but it was never reliable. Prior to this being released, I had tried both of the GPS fixes (configuration changes and the flashable fix) with no discernible difference to stock.

With that said -- this patch has fixed everything. I just stepped outside and had 9/10 satellites locked.

Thanks for posting!
[Vibrant Android Development] andy696:
I have just installed this whilst at work so I have not been able to fully test it but my initial impression is very good.

I turned on GPS test before walking between two buildings, inside I has 13 sat's in view 0 locks, as soon as I exited the first building the locks started coming in fast. I had 6 locks in the minute or so it took before I entered the second building. :)
[Vibrant Android Development] Dougefresh91:
Went to a few stores today and tested out the gps. Worked pretty well using map directions. Navigation lost signal twice half way through the ride so I gave up on that. I'll test it again tomorrow when I go to work.

My gps settings are all stock. Before this patch I'd lock on to one satellite at most, so this is a definite improvment. I've never had a phone with gps before so all I have to compare this to is my car gps, which is way more accurate. Phone also lost gps signal when it started raining, car gps did not.

I've installed the full Rom, and not the .zip. It seems as though the full Rom does not include*#*#1472365#*#*,LBSTestMode menu.
[Vibrant Android Development] rjwisniewski:
This is great. 11 in view, 8 in use. 27 ft. accuracy. That's doing a GPS test indoors. Can't wait to test this on the road.

Sent from my Samsung Vibrant using the XDA app.
[Vibrant Android Development] JeremyNT:
After a bit more use, I'm not sure what I think.

The good news is that the lock display bug is definitely fixed. The sat status in GPS Test now seems to be accurate and reports the correct number of locks.

On the other hand... cold lock time is long. No improvement there. Tracking still seems less than perfect. And the compass, although maybe a *bit* less janky, is still really poor.

If this is actually better, I don't think it's much better.
[Vibrant Android Development] scrizz:
well I flashed the whole ROM, and my compass works fine

I also run my GPS without "use Wireless Networks" setting

and it works great.
[Vibrant Android Development] j_r0dd:
It appears my compass is actually moving now and my gps is working a lot better, but still not were I want it to be. I haven't changed any settings. I just flashed the zip. 6/9 45' accuracy. Still better than saying I am in spain when I live in florida rofl.
[Vibrant Android Development] sfsilicon:
I'm interested in applying this patch. Does having the RyanZa one click lag fix installed impair the use of the updated zip file? I'd hate to have to back that out first before being able to try this fix.

My gps performance has been ok (not great) since I did the lag fix. before that it would lock up a lot.I'm guessing it is related to the gps needing to write frequently during start-up.

How would I go about manually installing the files?

Does any one have instructions to reverse the patch?

Ty!
[Vibrant Android Development] Keslynn:
This is fantastic! Maps locks on with greater accuracy in seconds instead of minutes. GPS Test shows me locking into 8/11 sats outside when previously I got 2 if I was lucky.

My SUPL settings are set on AutoConfig. Everything else is stock.
[Vibrant Android Development] KerryG:
Outside I got 8/12 this morning. I would say that is a vast improvement over my usual 2.
[Vibrant Android Development] dpereda:
This is a huge improvement.

Inside Tests

Before the Fix, See 0 Sats

(While on my G1 I could get 9~10, some signal, but no Lock)

After this Fix, I can see 8~10 Sats and get some signal on 3-4 of them, but no Lock.

Outside Tests

Before the fix, I could see 9~10 Sats, but only get signal and occasionally lock on 2~3 sats, Accuracy 200~1000 feet.

(While on my G1, 4+ sat lock accuracy 30 feet)

After the fix, 10-11 Sats, Lock/in used on 4-7 Sats in use, accuracy 30 feet.

Lock times outside were in the 1 min range, better than never locking, like before. I am going on a drive tonight and will test it in the car.

Overall not as good as my G1 GPS, but now it is useable.

EDIT: Now Seeing 9 Sats inside with 5 in use, accuracy 70 feet.

PS: I fix my GPS issue a while ago, Install mobile AP on the Vibrant and just used my G1 over the WiFi
[Vibrant Android Development] creator2456:
I just applied the fix to my Hybrid + TW ROM/MOD (http://xdaforums.com/showthread.php?t=779643) and updated it to v4.
[Vibrant Android Development] frankencat:
It works with RyanZa's lagfix. :)
[Vibrant Android Development] Goog1e Phone:
Weird, I'm can't seem to get this working. Feeling like a complete noob. Flashed this through clockwork. Ran the GPS test and cant seem to pick up anything. I flashed it over Eugene's R3 rom. Before I had JAC's kernal, but ended up removing it.

Is anybody having success with this fix and the hybrid r3 rom?
[Vibrant Android Development] designerfx:
Works. Prior to patch I had the spl settings to use google, flashed this and lock instantly and notably no magic movements stopped at a red light.

Fixed!
[Vibrant Android Development] backslide311:
Just install via clockwork! I use the OCLF and have had no problems.
[Vibrant Android Development] demo23019:
Wow GPS actually works now, even indoors

thanks for posting OP
[Vibrant Android Development] g1flasher:
Sweet just flashed this and it is a huge improvement. Prior would see 20 or so birds with maybe 1 lock if any. Tested out side and locked 8 out of 12 birds in a matter of moments. Accuracy was down to 10ft before I canceled the app
[Vibrant Android Development] Tynen:
Worked amazingly on my unbranded Galaxy S. :)
[Vibrant Android Development] JeremyNT:
That's the rom I'm using, and it flashed fine.
[Vibrant Android Development] Maverick777:
This fix is simply amazing! My GPS has never worked so well. Fixed 7-8 satellites 30-40 feet accuracy within 30 seconds. Another minute and I locked onto 10-11 satellites with 15-20 feet accuracy.

Amazing!

This is the fix I've been hoping for. Good job Samsung. Now we just need a bug free 2.2 update that hopefully addresses the file system and/or lag. :D
[Vibrant Android Development] azul591:
Happy Happy Happy

I am pleased to announce that my GPS issues are finally put to rest....this is the first time I got a lock within 15ft accuracy and at least 7 sats locked and 13 in view. I got the phone the day it came out and love it....GPS was my only downer...until now....thanks Frankencat
[Vibrant Android Development] wookieloou:
VERY noticable improvement for me. +1 for this.
[Vibrant Android Development] Keslynn:
I'm running R3 and it works well for me. That being said, it did take a little bit (a few mins) for the initial lock but ever since it's been really snappy.
[Vibrant Android Development] t1h5ta3:
worked perfect for me. 12sats with 9 locks in less than 10 secs from a fresh boot. signal levels seemed stronger than in the past as well.

post via xda app
[Vibrant Android Development] dpereda:
Just an update to my post, now tested in the car..

Works great. No random movements, I don't have to keep the phone on my dash to keep a signal. On a 40 minute drive, only once did I lose lock, and that was at the gas station.

As for google maps taking me to the wrong address, that is for another post.

Thank you all who put this out
[Vibrant Android Development] bruno.borges:
Could you name this app so I can find it on Market?

Cheers
[Vibrant Android Development] zoid_99:
Worked great last night and this morning... Tonight it can't see any sats at all. WTF? Did I toast my GPS chip?
[Vibrant Android Development] Goog1e Phone:
I get a few sat but I can't lock onto one. Trying to use google maps and it keeps telling me I have to wait for location. Currently this fix isn't working for me. Dont know what else to do.

easy to install and works great not perfect but considering how it was workin im not complaining lockin 6 sats out of 9 at 30 feet accuracy thanks for this
[Vibrant Android Development] yespinosa:
Yup same problem no lock onto anything sees 14 no lock im giving it till tomorrow then nandroid it is if anyone has any clues aa to the cause of this please enlighten us.
[Vibrant Android Development] ultra spikey:
I'm locking 7-8 satellites with ~30ft accuracy after the fix. BUT, google maps/navigation is still loosing signal. I took a 15 minute trip back to my apartment while watching google maps, it lost signal 4 times, and went of course a few times.

I see most people here are just using the GPS Test app to test the fix. While this app does show it's connecting to more sats, with better accuracy, try a real world test. Use Navigation or My Tracks while on the road and monitor it.
[Vibrant Android Development] kiapolo:
Working fine for me...getting 13 sats in use in downtown Honolulu with an avg 24 feet accuracy and about 12 feet accuracy in the burbs.

I've got no difference on Eugene's Hybrid R2 ROM in NYC.
[Vibrant Android Development] drastic61:
Works beautifully, very accurate, I finally feel like my phone is complete now.

[Vibrant Android Development] bauerlucas:
So like some of you I flashed this and it didn't work... What I did was bring the port and stuff back to stock. I did the quick fix that didn't work so I un did that. If you need stock settings try google. dial *#*#1472365#*#* and bring it back to stock then click delet gps settings and reboot worked like a charm locked onto 9 out of 11 in seconds. Whooooooooo
[Vibrant Android Development] Goog1e Phone:
Still didn't work for me. Went back to stock settings. And wiped it. Rebooted and it didn't work. So I flashed this GPS files again, and still no luck. I'm think I'm going to wait until Eugene integrates this into his R4.
[Vibrant Android Development] creator2456:
It's already integrated into Hybrid + TW v4.
[Vibrant Android Development] Goog1e Phone:
Don't want to lose all my data and nandroid flash Hybrid +TW v4. Although I appreciate your work. Just waiting for an update.zip one day (dialer + contacts + gps fix.) that can be flashed on top of Eugene's R3.

I just don't get why I'm not locking onto any sats. Even though I can see 6-8 of them.
[Vibrant Android Development] smashmouth:
So is anyone noticing sporadic lag issues here after installing this update?… I believe I’ve read “after installing” that this update causing lag issues, and that would identify the issue I am seeing with my Vibrant.

Damn to.. cause I just deodexed the **** out of it and bumped it up to 1.2 Ghz… was running smooth like real smooth .. 2492 on quadrant but now, every now and then I notice lag… this didn’t start till I updated ..

Anyone have the original file so I can flash back and compare? If not, I’ll just load my rom from the back up and see.
[Vibrant Android Development] lqaddict:
The GPS does lock on more birds, but is still highly inaccurate according to My Tracks - tested in the skyscraper jungle where my Garmin and TomTom GPS units will get confused, and the Vibrant is on par; another test was done at an open field away from any obstruction of the skyline, and My Tracks was all over the place.
[Vibrant Android Development] ultra spikey:
My theory about this "fix". Looks like Samsung might have just lowered the signal standards for locking in a satellite. So while GPS Test may say you've locked in more satellites, you've just locked into satellites with a low signal, satellites that your phone was previously able to see before the fix. It just did not lock into them because the signal was weak.

Thats the only thing I can think of, that would cause more locks but same flakey results.
[Vibrant Android Development] boomerbubba:
I can easily think of another explanation: A flakey test environment.

How do you know that this simple method of copying over selected files includes all the code that affects GPS performance? All we know from the original post is that "someone posted the GPS files from the newly released firmware," but we have no clue that "someone" even knew what to include. Better to flash the whole ROM and test that.
[Vibrant Android Development] zoid_99:
Unfortunately that is what it looks like to me as well. Last night I could not get any locks where earlier in the day I was getting 8/10. I decided to use ODIN and install the full rom. I can now get a lock on 8 or so aout of 10 or 11 but accuracy is still just as bad as the original rom. Look at my drive in to work using MyTracks. Zoom in and look at how bad my driving is. I can't seem to drive on any roads and I love to drive crazy at stop signs. This is just as bad or worse than the original ROM. Hopefully this isn't Samsung's real "fix".
[Vibrant Android Development] scrizz:
maybe you guys should flash the whole firmware..

I've been on it since it came out, and my GPS and Compass still work flawlessly.
[Vibrant Android Development] zoid_99:
I did... here are my results:

http://maps.google.com/maps/ms?ie=U...25684842192660.0004904bb079c51285324&t=h&z=14

Far from flawless....
[Vibrant Android Development] timafey:
I'm curious did you guys turn off use wireless network for location? This made my accuracy about 20 ft in google maps after only a few seconds of searching for my location. Give it a try if you haven't yet
[Vibrant Android Development] frankencat:
I agree with the "how do we know" part and it's entirely possible that there is something else in the firmware that works with the updated drivers, etc. I guess we just need to test it and see if there is a difference.

What I do know is that myself and many others have vastly improved GPS performance after applying the new files contained in the package and are happy with the results. Before I packaged it up into a zip file a few other folks manually copied the files over and reported improvements which is what got me interested. I am glad this helps a lot of people and I am not sure why it is not helping everybody but there are so many variables that could be causing this not to work for those few. The good news is that it does look like it is being addressed. I guess we will have to wait and see. In the meantime, give it a try. The worst that can happen is it doesn't improve anything. On my phone it is a major improvement and I could totally live with it the way it is. :)

Peace.
[Vibrant Android Development] jdkackley:
Nice Work!

Nice work FRANKENCAT! I used this fix, locked on to 8 birds with the majority of those birds having a signal greater than 25. My accuracy was down to 18. All tested with gps test. I would have to agree that this is far improved from ANY of the previous fixes. KUDOS! :D
[Vibrant Android Development] tedybear:
I get quick locks on multiple birds, but the accuracy is crap. I use "MyTracks" to walk for exercise. My old G1 was dead on accurate while in my pocket out for a 4 mile walk on city streets. The G1 track was accurate enough that you could look and see what side of the street you were on. The Vibrant with this fix locks on super quick now, but on my walk it showed my max speed at 24.6 miles per hour, and the track is off up to half a block at times. I really hope this isn't the solution that Samsung pushes out in the next two weeks.
[Vibrant Android Development] frankencat:
tedybear, would you be interested in flashing the whole leaked ROM and letting us know if you get better results?
[Vibrant Android Development] frankencat:
Thanks but it's really not my work. I only packaged it up for general mass consumption. :)
[Vibrant Android Development] sfsilicon:
Thank you!
[Vibrant Android Development] zoid_99:
Hey Frankencat,

I did just that last night when i was having issues with the zip flash. I installed the leaked rom and I'm still having issues with accuracy so I don't think it's the files you packaged up. I'm wondering it my GPS is a lemon.

Here's my track from this morning. Zoom in and see how bad it is: http://maps.google.com/maps/ms?ie=U...25684842192660.0004904bb079c51285324&t=h&z=14
[Vibrant Android Development] frankencat:
Yeah that's not gonna work for walking ;) Can you post your GPS settings? Just curious. Thanks.

Edit: It looks like you ran through the McDanald's drive through. Did you get a shake or a fruit cup? lol. :D
[Vibrant Android Development] zoid_99:
Hah.. not only did I go through the drive through, I drove though the building (and a Wendy's too).

How about the SUPL settings?
[Vibrant Android Development] heygrl:
Looks terrible, do another one. I'll be testing the Vibrant vs a Motorola CLIQ real soon. So far as I can tell the CLIQ is much worse than my Vibrant. Pulling into an area of homes resulted in an extremely rough estimate of my location, The Vibrant was much better.. it's a shocker!
[Vibrant Android Development] zoid_99:
Here's another quick one I did @ lunch.

[Vibrant Android Development] bauerlucas:
So are you saying this is a hard ware problem and they howe no one will notice the quick fix?
[Vibrant Android Development] Globespy:
SMASHING!!

Flashed this zip and within 20 seconds I had 7 locked SATS out of possible 9.

Quick search on my location got me within 2-3 meters of where I was actually standing!

So great to have this GPS issue fixed as I was seriously getting tired of my phone because of the lack of reliable GPS.

Thanks so much OP!
[Vibrant Android Development] ultra spikey:
No..I'm just saying this "fix" doesnt fix anything. Maybe the zip is missing some other required files from the leaked rom? Maybe the leaked rom doesnt fix the gps at all?
[Vibrant Android Development] MINUS Stl:
Since day one I've never had a decent working GPS on this phone. I've tried all of the "fixes" to no avail. Never really bothered me since my car has nav. GPS Test would show 1 sat in view but never in use. Went ahead and flashed this yesterday. :eek: BOOM! Multiple sats in view and use in less than 2 minutes (first time). So IMO....it works.
[Vibrant Android Development] Globespy:
+1

I just had the same experience. It's a software thing and now its fixed
[Vibrant Android Development] zoid_99:
Nope.. not fixed.
[Vibrant Android Development] frankencat:
Hey zoid, if you could post your SUPL settings that would be great.

Here's my settings...

Application Settings -

Session Type: Tracking

Test Mode: S/W Test

Operation Mode: MS Based

Start Mode: Hot Start

GPS Plus: On

Dynamic Accuracy: On

Accuracy: 150

Use Skyhook: Off

Use PC Tool: Off

SUPL/CP Settings -

Server FQDN Type: Auto Config

SUPL Secure Socket: On

AGPS Mode: SUPL

I am not sure how much the top ones really matter (Application Settings) but I am pretty sure the bottom ones (SUPL Settings) could have a big impact on how the GPS works and whether or not the new files are going to work for you. Give it a shot if you are so inclined. I want it to work for you buddy! :)
[Vibrant Android Development] barch27:
The GPS issues appeared to be fixed earlier, but now I'm not so sure. The problem is that it takes forever to get the initial fix (GPS Test shows 12 in view, 0 in use for a long long time), and sometimes it does not succeed at all. Once the fix is achieved, things are quite smooth for a reasonably long time.
[Vibrant Android Development] ultra spikey:
Install My Tracks, drive around for about 5 miles while recording, then post your track here... that will be the real test.
[Vibrant Android Development] designerfx:
Hey zoid what are you using to track and display your results?
[Vibrant Android Development] johnnyh64:
It's called My Tracks available in Market. There is an option to share your tracks with others.

I too notice that more satellites lock but the accuracy is actually worse. I don't seem to get much better than 50 ft. where I use to get 20-30 ft. I flashed the entire leaked rom.
[Vibrant Android Development] Globespy:
ermm......can I take this back. I went for a drive today and the GPS found it difficult to map my location when I was moving.....it looked like it was about 30ft out and 'jumped' around the map up to 100ft away.

It's still an improvement over before where I found it hard to keep a lock, but it's still nowhere near perfect.

Hopefully there's more to come from Samsung.......
[Vibrant Android Development] eklipz3:
no problems here worked fine for me.
[Vibrant Android Development] adamcooks:
After flashing this, i saw improved accuracy using gps test. In my real world test, across the bay bridge, which it has never stayed locked on before. Kept signal, remained locked on whole time, even in tunnel in the middle. thanks for the d/l
[Vibrant Android Development] PaiPiePia:
It happened in my driving test as well. Try turning off agps support in the GPS settings and just use GPS alone seems to solve the problem for me.
[Vibrant Android Development] remarquian:
My experience tonight with the fix and Google Navigation is that it put me at times eight to ten miles away from where I actually was.

It was surreal.
[Vibrant Android Development] frankencat:
Weird, it's right on the money for me with no drift and <20 ft accuracy using Google Nav.
[Vibrant Android Development] swehes:
It worked

I voted that it didn't fix anything for me. However when I checked the firmware on the phone I noticed that I flashed the original back onto the phone. So with that said I reflashed the new firmware and it works much much better now. The My Track app is doing great for me at this point as I test different routes to and from work.
[Vibrant Android Development] mmalott:
Getting much better satellite locks with this from testing around the outside of my house. Use to get about 2 locks and now getting about 6 or so. Some apps still refuse to lock in tho (twitter for android is one).

It appears that the apps that wont lock is due to a timeout period. Like Twitter for android attempts to locate for about 10 seconds or less causing it to timeout and say it cannot locate.

Sent from my Samsung Vibrant using the XDA app.
[Vibrant Android Development] Globespy:
Made one change in addition to flashing the GPS zip....changed SUPL settings to 'MS' and that seems to have helped.

Recorded a 10 mile (or thereabouts) trip this morning with just a few little issues, although these were close to places on the freeway that had overpasses.

I could not watch it all the time, but it seems to have kept a lock.

I have not tried this in a downtown high-rise building area.
