THe GPS nows locks on within 10 seconds and I am getting from 5-8 sats out of 10 or 11. A drastic change from before when it would lock on in about 45 seconds to a minute, if it locked on and at all and have from 0 to1 and if the moon was right 2. Also before this update it would lock on and off continually and now in a day and a half it seems to just stay locked on. Very happy with it now as it is now usable. Cardio Trainer now works and is consistent as is My Tracks. I must say a world of difference.
[Vibrant General] zoid_99:
Before flashing this I was lucky to lock onto 2 sats. After flashing I locked onto 6/9. Seems accurate enough. Will test with mytracks tomorrow.
[Vibrant General] 30Glock:
Excellent here, Tracks perfectly, Locks onto 9 sats w/o issues, Those that said it was a hardware issue, I expect a full apology, LMAO.
[Vibrant General] rakeshchn:
Put just the GPS fix from this thread and tremendous improvement.

http://xdaforums.com/showthread.php?t=782242

Locks 10/10 sats outside and 20 ft accuracy!
[Vibrant General] SamVib:
A great improvement. Locked on in 3 seconds flat. It's pretty much gone now.

And people said samsung was horrible.

This message is brought to you by my Samsung Vibrant, using the XDA app.
[Vibrant General] KerryG:
I didn't feel like flashing the entire rom so I just used the GPS Update file and its working great. I have never had a lock indoors with the Vibrant and it locked in a few seconds to 6. In the morning I will try it outdoors.
[Vibrant General] heygrl:
People doing this shouldn't post here because there could be other changes under the skin that DON'T change with this method.
[Vibrant General] zoid_99:
Do what? Sure there may be other changes but why say they shouldn't post here?
[Vibrant General] kizer:
Personally I could give a rip what other changes there are or to come. The fact is the zip file either works or it simply lowers the required threshold of the GPS to get a lock.

So either we are really seeing an improvement or Samsung is basically lowering their standards and hoping we will too. To say we shouldn't post here is well I don't know insane. The GPS still needs work, but its one step farther than we have been since the phone came out.

For the record I voted: gps is better but still needs work

10meters is still bad in my opinion, but its better than 30meters that I had before and I'll take that since it was what 30seconds worth of work on my behalf.
[Vibrant General] heygrl:
Because it's pollution, it's not the same thing we've done. Why don't we just have people posting with stock Vibrant's too? The OP and Title specifically states "GPS with New Leaked Firmware" and not files pulled from the firmware that probably changes half of what needs to be changed.
[Vibrant General] zoid_99:
I agree with this. To me it looks like you nailed it saying they lowered the threshold for individual sat locks. Accuracy is still bad and I still drive through buildings using mytracks.
[Vibrant General] versedout:
Tried the fix, the GPS still isn't any better. Still hoping for the best from Samsung.
[Vibrant General] heygrl:
What "FIX"? ugh

It quite obviously receives the signal a LOT faster than before, lowering the "threshold for a lock" won't improve that. You need a signal before you can get a lock

My Vibrant with the firmware updated is sitting next to MOTOROLA CLIQ at 5M, while the CLIQ is at 3M both in GPS Status and not Google Maps. Not only that but the compass is pointing in the right direction! I wonder how the .zip file fixes that.
[Vibrant General] larryccf:
zoid - you have no idea who you're arguing with - don't waste bandwidth

as to the unofficial firmware, i flashed it, and all i can say is "wow" - where my gps had gotten so bad it's accuracy circle was somewhere in the area of 1 mile, never getting a steady lock on more than 2 sats, after the flash it went to 7-8 locked out of 12 in view

did a 9 mile circuitous drive, all secondary roads, even did a circle in a gas station that had a huge metal canopy over the pumps - MyTrack logs was perfect except for one anomaly - it showed me clipping my neighbor's lawn by maybe 10 ft when i turned the corner at his house. Odd thing was i stopped before making the turn to look at the MyTracks map and it showed me at the very corner - it was later looking at the log i saw what it had recorded.

the other changes were all great, but this was what i was looking for, GPS wise - the entire trip it showed me in the actual lane i was in (some of those roads were 4 laners), and except for the one incident above never showed me in the weeds or 75 ft over in someone's yard or driving thru their house

i had the lag fix before flashing and was pulling 2000 - 2200 benchmarks before, now i'm pulling 850-900 but everything is as snappy to open as with the lag fix, markets, camera, etc

unfortunately i sent the vibrant back to tmo yesterday - had a 16th of sept return date, and there was one other issue with the screen that had developed, and in doing the flash something happened to the volume button - it had been loose, and it got "rattly" loose when pulling up the download screen

figure i'll wait till the g2 comes out and see if i like it better or buy another vibrant, but thumbs up to sammy on this firmware - i really had gotten cynical they would or could pull this off
[Vibrant General] zoid_99:
I can tell you how it the .zip file fixes it.... It doesn't.

The reason I said it appears to be lowering the threshold is that it looks to me like the signals are no different than before the "zip fix" however in GPS Status 6-8 of them go green and "fix". That appears to be the only difference. I'm not seeing any difference in accuracy.
[Vibrant General] smashpunks:
I agree with this. If you didn't flash the whole rom but only gps files, who says your getting the whole fix?

I say 10 meters is good enough for me. Maybe not some of you but I can find the other 10 meters with my eyes that the GPS wont. No biggie.

I agree also with heygrl as now this poll isn't proper, it was supposed to be the whole leaked rom not just files, so now we may be getting 2 different results...

Whatever the case, both the leaked rom and GPS files seem to be working nicely. Just don't know if the majority of those good now are from the whole rom or just GPS files etc.
[Vibrant General] scrizz:
I did the whole ROM, and glad that I did.

It is much better than the JFD.

Plus, I don't need a lagfix.

I didn't buy the phone to run quadrant on it.

If it feels snappy and fast, that's good enought for me.

No lag here on JI2
[Vibrant General] LovellKid:
Im in between saying its great and it needs work. My Mytouch was better and I think eventually this should be atleast on par with that. I used Eugenes fix incorporated into his ROMs to test a drive home, and it was much better than stock, but still would bounce around, had me in the middle of a field moving around while I was stopped at light. i would only get MAYBE a lock on 1-2 sattelites if I was lucky. Using maps was awful. I flashed the the GPS fix and I immediately got 9 sat locks, and navigated PERFECTLY on the way home last night. Im glad to see this because im heading to Colorado this weekend and needed maps. FWIW
[Vibrant General] FurtiveDeimos:
I'm excited to hear that the gps will finally be useful but the broken compass is almost more annoying than the busted gps in my opinion.

Does this leaked rom address the compass issue at all?
[Vibrant General] Sane1:
GPS doesn't work at all on my phone. Fix or not the phone can not find my location at all. I might have to exchange it.
[Vibrant General] kizer:
Just tried it again at work. 15seconds gave me 8 out of 11 locked with a 4meter error. I still have wireless on opposed to turning it off and just letting the GPS find my location.

Afterwards I ran Google Maps and it showed me pretty close to where I should be. Sure the zip isn't probably the 100% solution to why the GPS is off and why the compass is still useless, but its a great start.

When I commented earlier about lowering the threshold I'm wondering if Samsung set it to high in the first place or something else to the matter. I know my 4,000 work GPS has a few settings on it and I can set it to high for precesion, but often it will not lock on many Sats until I allow for lower strength locks. At the lowest setting I can get max Sat coverage in a few seconds. In the middle setting I normally get 4 or 5 with mixed accuracy.
[Vibrant General] smashpunks:
Must be the reason your compass don't work. Mine works great ...
[Vibrant General] krichek:
My compass finally works great as well. As for accuracy I must be one of the lucky ones because my GPS consistently shows in the 10-20 foot range in GPS test and in google maps it varies between 5 and 8 meters normally.
[Vibrant General] heygrl:
I will say this. WiFi seems to affect the fix. If I have it on (with Wireless Networks on), my WiFi will give me a 50 meter fix that's more like 1 meter but it won't even look for GPS if I haven't recently done so. Disable WiFi and GPS locks in seconds. Minor but worth noting incase other people on WiFi notice no GPS activity under GPSTest.. this is sporadic.
[Vibrant General] Coniac:
used the zip file and works great. finally I can use my google maps/navigation!! I get 11 in view and like 9 locked.

yay!
[Vibrant General] scpieps:
I flashed

just

the GPS files and it now works great. Went from taking 5 minutes or so to "lock," constantly losing that lock, 1 or 2 satellites out of 12, and accuracy of 50 to 150 feet to locking in 30 seconds, remaining locked on 10 or 11 satellites out of 12, with accuracy of 20 feet or less.
[Vibrant General] rjscott2005:
I'll cut to the chase- Before I flashed the GPS only file I could not maintain a GPS fix here in metro-Atlanta or in Rochester, NY. I'd get very occasional fixes that would last for just a few seconds using Maps or Navigation. Same results with and without the GPS settings 'fixes'.

After flashing I get what you see in the following images. I've also included images of my settings used during the screen grabs.
[Vibrant General] kizer:
Must be the reason my compass doesn't work. I'm confused. What are you using for a compass app and what are your settings. I just turned wireless off and well it still borked.
[Vibrant General] avogl:
My compass works great (after the update) but I do have to do a figure 8 to calibrate it. Fast to respond and accurate after the calibration but it does need to be calibrated.
[Vibrant General] smashpunks:
I'm using a app called compass. Or go into Google maps, streetview and use compass mode. But the compass works best.
[Vibrant General] heygrl:
That's what I got from it, I said your compass wouldn't be fixed by flashing those files so why mention it here? We've got the firmware flashed and a far more accurate compass, but that's still for a totally different thread... this one's about GPS
[Vibrant General] jellyculligan:
Question about GPS Fix

So it would seem to be a noticeable difference here, but curious if these results are also achievable indoors and while not in motion, or walking (google maps walking navigation, etc)?

Thanks, exciting stuff! hopefully not a placebo.
[Vibrant General] smashpunks:
I've tested in all situations . Honestly IMO it tracks better moving. Even works in doors, not as fast as outdoors.

Regardless of lock times I've never gotten more than 3 satellite locks. Now i get atleast 7
[Vibrant General] jellyculligan:
Question about GPS Fix

Does this still work wiht the supl.google.com server settings or should we revert back to the original factory settings?

Thanks!

Kelly

Samsung Vibrant TMobile
[Vibrant General] jellyculligan:
Thanks for the update SP,

cheers,

kelly
[Vibrant General] boomerbubba:
Another tester in another forum tried changing the SUPL server settings, per my suggestion (his Test #3), and reported very bad results compared to the stock settings.

I have come to the conclusion that it is better for amateurs not to monkey with the SUPL server settings. However, it does make sense to try enabling MS Based mode in the A-GPS settings instead of Standalone.
[Vibrant General] kizer:
Thanks for the response. I use compass all the time and well my phone things West is North. LOL

Not sure if its because I'm using Vibrant7 or something else. Beats me.

Anyways sorry to stear the thread to the compass......... anyways no more mention from me.
[Vibrant General] smashpunks:
I flashed the GPS fix also just for shats n giggles lol :D
[Vibrant General] Maverick777:
Flashed just the GPS fix. Using Eugene's Vibrant 9 FW. Works amazingly well.

This is case closed for me as far as GPS goes. Now we just need 2.2 and lag fix.
[Vibrant General] heygrl:
Try flashing the actual firmware that goes with those files.
[Vibrant General] zoid_99:
Got an easy way to do that on a Mac?
[Vibrant General] speoples20:
Tested it today and worked great. Locked on to 6 satellites and navigation worked great.
[Vibrant General] zoid_99:
Interesting situation this evening... Flashed the zip fix last night and all looked good (kind of). Tonight I get 0/0 after 10 mins of standing outside. That is zero of zero. Can't see any sats. Wonder what's up with that. Anyone else?
[Vibrant General] zoid_99:
Don't flash the .zip ;) It will quit working after a day or so.
[Vibrant General] kizer:
Next day here and I still get 9 Sats.
[Vibrant General] zoid_99:
It would not get a lock using GPS Status. I did the *#*#1472365#*#* and went to the LbsTestMode and it eventually locked. Nothing like it did last night or this morning. After the phone sleeps it again takes forever to even see 1 sat.

I'm in the process of installing ODIN on a PC so I can flash the full ROM.
[Vibrant General] zoid_99:
OK.. First ever ODIN install worked great (once i found a PC to use). First thing I did was download GPS Status. I had my wife's stock Vibrant beside mine. Went outside and the updated rom locked in about 20 seconds with 6 of 10 sats. Wife's took much longer to lock but eventually did with 1 of 12 sats. My accuracy was 35-40 ft where my wife's was around 20 ft.

Next I launched google maps on both. My wife's show that we were in our back yard about 10-20 feet from where we actually were and mine with the new flash and the 6-7 sats locked showed me in the front yard much further away.

I give up. From what I can tell the new sat locks mean nothing. on a side note the compass is working better.
[Vibrant General] zoid_99:
After flashing the entire rom and not just the zip my GPS is still just as hosed as before. It may say it's locking onto more sats but the results are no different. For instance look at this track.

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

Notice how the accuracy is way off and the it does the "Hokey-Pokey" when I stop at a redlight. Hopefully this isn't samsungs real fix.
[Vibrant General] avogl:
This morning (2 days after the rom update) the gps would not load the almanac from the supl server and was not seeing any sats. I restarted the phone several times and as well as deleted the gps data several times (LBSTestMode) to no avail. I then took a 10 minute walk during which it eventually (slowly) found 9 sats but would not lock on any of them. I then reset the gps data again restarted Position Test and it immediately loaded the almanac this time and I had lock on 8 out of 10 sats in 5 seconds but the accuracy was 50m (160ft in GPS Test which I was switching between with Position Test) and wouldn't improve. I deleted gps data again restarted Position Test and it immediately loaded the almanac, locked on 9 out of 10 sats and had an accuracy of 6m (20ft). So now its working again as it has for the last 2 days but there are obviously problems with the new rom that still need to be addressed. I also find that the overall accuracy is no better or worse that it was with the original rom and 0-2 sats locked and that the compass works great when calibrated.
[Vibrant General] ultra spikey:
I flashed just the fix. Getting 7-8 sat locks with ~30ft accuracy, according to GPS Test. But using it in real world(eg. Maps, Navi, MyTracks), it is still flakey and loses signal.
[Vibrant General] smashpunks:
Unfortunately I also found GPS going back to crap. Oh well, its a start, atleast the time is now correct on it and other stuff were addressed like signal, compass (still works fine), etc. So whatever.

Basically back to square one. Wonder if Samsung let this slip for some real world testing purposefully . ? Hmmmmm whatever, ill have faith. X
[Vibrant General] heygrl:
What fix? You mean this new firmware?

LBSTestMode refuses to work (it seems like the entire app was removed) on this new firmware. How are you managing to use it? Installed it?
[Vibrant General] heygrl:
Still working just great for me.

I did a track of my CLIQ next to the Vibrant when I pulled into a housing sub division and the CLIQ was much worse. Maybe HTC has it down but it's not the worst tracking I've seen and HTC still goes off the road (contrary to what someone else claimed) and will track you next to the road. HTC could use a lesson in cellular radios/antennas. The G1 and myTouch are pitiful. My Vibrant is much better.
[Vibrant General] avogl:
The string does not work in the new rom to get access to LBSTestMode. I used LauncherPro to set up a shortcut to LBSTestMode using Shortcuts/Activities/LBSTestMode. This will let you set up a shortcut instead of having to enter the string which doesn't work now.
[Vibrant General] ultra spikey:
Not the firmware. There's a flashable zip that includes the new gps files. It's in the development section.
[Vibrant General] heygrl:
It's not the firmware, this thread is for the firmware which includes a number of other things like a working compass (better GPS Navigation)

I tried accessing LBSTestMode via the .apk file but it wouldn't open. I'll try launcher pro.
[Vibrant General] boomerbubba:
It does take "testing purposefully" to isolate and explore these complex technical issues. Users should stop shooting from the hip either pro or con without some rigorous testing and facts to support opinions and speculation. Yes, that means you. I have to ask again what someone else asked you on another of the numerous threads you spout off in: Are you 12?
[Vibrant General] smashpunks:
Edited to follow forum rules. Grrrrrr *
[Vibrant General] snowdogging:
Many people have said it many times in many threads....The number of sats in view, number connected, and accuracy are numbers that actually contribute to the GPS conversation. In that regard, this poll is extremely unhelpful and only adds to frustration levels.

"GPS test" in the market is a great app that will provide the helpful numbers. Here is a link.

Oh, and the obvious....:cool:

[Vibrant General] krichek:
I am not a regular poster here at XDA, so sorry for the late reply.. I did a Mytracks yesterday along side my original Droid as a test for another forum that I frequent.

I'm not sure what happened on your test but mine was quite different. I have made one change to the default setup tho, in that I have changed from Standalone to MS Based in LbsTestMode. All other defaults were left in place including disabling "Use Wireless Networks"

Here are my tracks:

Vibrant: http://maps.google.com/maps/ms?ie=U...937463234440126188.0004903d988a6db6d8e80&z=12

Droid: http://maps.google.com/maps/ms?msa=0&msid=217713586391012693858.0004903c328e28e02360b
[Vibrant General] boomerbubba:
A word of caution about drawing early conclusions after making changes to settings in LbsTestMode:

Reportedly, just invoking that utility at all has the effect of reseting the GPS cache, regardless of what the change was. This has created false impressions in testing other Galaxy ROM variants, especaially those whose symptoms came on after a passage of time -- indicative of corrupted or out-of-date almanac or ephemeris data in the cache as a root cause of problems. So if a device is afflicted with such a problem, and the user goes into the LbsTestMode and changes the value of Setting X from False to True, they can be fooled into thinking that was what cured the problem, when really it was just the cache reset that is a temporary workaround.

The history of testing GPS "fixes" on Galaxy S platforms is littered with disappointments. So it is wise not to declare "Eureka! It's fixed" prematurely.
[Vibrant General] heygrl:
No, I've identified the problem. aGPS will not download new data if you're on WiFi. That's it. GPS still locks on, unlike before when it would stop completely after a day or so. I'm going to give MS-Based mode a try because locks are instant with it and I like that.
[Vibrant General] zoid_99:
Ok, so I thought this wouldn't help a thing but I did it anyway except I changed it to MS Assisted by mistake. Look what happened:

http://maps.google.com/maps/ms?msa=0&msid=201142930973527917117.00049060180af6659398c

The track is dead on.
[Vibrant General] heygrl:
Going from 3G to E will sometimes cause your lock to be completely lost. If you're in Standalone mode getting a lock will take upto 20 seconds in most cases.. MS based mode is like 3-5 seconds at the most.

http://maps.google.com/maps/ms?hl=e...22653250295432.00049063685873acbe8e0&t=h&z=14

All tiny streets (Decatur has undergone major construction so most of the map itself on that street is not accurate) - all residential areas. Why wouldn't work for Navigation again?
[Vibrant General] bellrb19:
I wonder where the people who are still having the bad GPS's are located. I saw that there were a couple people on the west coast that had this issue. I am located by Seattle and have 6 sats in view but none of them lock on. I have tried maps and the gps test app running for a couple minutes each.

At least the gps hasn't caused any lock ups but this is ridiculous.
[Vibrant General] heygrl:
Have you disabled WiFi like I said before?
[Vibrant General] krichek:
I live in California (about 40 miles north of Sacramento). With the old rom we are currently in what I refer to as the "dead time", which is a window of time during the day where my GPS will not lock onto any satelites when using the original rom. This window for me was roughly 3 hours and 20 minutes long.

I am looking right now at 2 Vibrant's. One on the old rom and one on the leaked rom sitting on my kitchen table.

Old rom : 11 sats in view, 0 locked

Leaked rom : 11 sats in view, 7 locked
[Vibrant General] boomerbubba:
Do you think you have to have your WiFi radio disabled, or just not be connected to a WiFi access point?
[Vibrant General] smashpunks:
So far the leaked rom with Ms based on works fantastic. Even getting locks in doors fast. Before Ms based first lock was fast, then kept getting longer each time. Ms based on seems to be working awesome . Locks are consistent in time.

Yea yea, ill give it a couple more days, but if it stays like this, I'm cool. Fingers crosses.
[Vibrant General] heygrl:
Just to not be connected to a WiFi hotspot but disabling it would take out any and all guesswork.
