Gps fix 101

EDIT: 9/21/10
NEW FIX OUT!!! http://forum.xda-developers.com/showthread.php?t=782242
Like many of you folks, i've been having lots problems with the GPS. And like many of you, I also am upgrading from the G1 so I know how a good GPS signal is suppose to be like. In many instances, the GS would not sync with the GPS when under the same circumstances, the G1 had no problem.
Inside my home it will rarely connect. When testing with the GPS TEST, the damn thing would not even connect to a satellite.
AFTER FIX - Everything connects REALLY REALLY FAST and ACCURATE
PS - These are not my own but I found them online by username e-wrecked
STEPS
1 - Disable "Use Wireless Networks" - Settings / Location & Security
2 - Dial *#*#1472365#*#*
3 - Under "Application settings" Change "Operation Mode" to MS Based
4 - Under "SUPL/CP Settings" Change the SERVER & PORT to supl.google.com and port 7276 [ Do not use www. in front of supl]
5 - REBOOT
6 - Turn back on the "User Wireless Networks"
7 - Praise God
----------------------------------------------------------------
PS - If you need to get back to default here are the specs
DEFAULT - OPERATION MODE - Standalone
Server - www.spirent-lcs.com
Port - 7275
THERE IS A NEW FIX OUT!!! - http://forum.xda-developers.com/showthread.php?t=782242

all of you who insist that this is a hardware problem, get out of here with that

never mind...

has anyone tried this yet?

I tried it, and so far so good.

This worked to gps is fast now

thank you much...
edit: Sweet, Got a lock in like 1 min. outside around a bunch of buildings on a really cloudy day.... Not sure if this fixes it completely but It works great for me so far. Ill do more testing obviously but nice job op...
Xda rocks. People all help.. Loving it
edit2: Ok I shut gps and my location off. Then turned on my location. Went to google maps typed in tmobile, then went navigate too, it opened up my gps panel, I turned gps on, hit back to go back to the navigation, it now locks in about 5 seconds on a major cloudy day around buildings got a lock, last night I couldnt get one in minuetes.. Very awesome... Great job again op

I was starting to have buyer's remorse because I use my phone for navigation daily. About 30 min ago my internal dialouge was: "Sh!t, I sold my iphone for this and the gps barely works!"
I decided to check if xda-dev had a fix posted and hot damn there it was my gps works awesome! Albeit I was very sceptical and I bit a couple of nails since the first fix was slow (maybe cold with new settings), but every subsequent fix has been lightning quick!
Thank-you very much for posting the fix!
By the way the Vibrant is miles ahead better than the iphone. If this problem occurred on the iphone I would have waited 3 weeks before Apple would stop denying there was a problem and then tell me to buy and external gps for it to work properly - just poking fun at apple.

+1 How true.
This fix is exactly what was needed. Thanks to the OP.

Since applying the fix, my phone is taking noticeably longer to boot to a useable state. Previously, the phone would boot into the OS and be snappy within seconds. Now, it's taking me ~1min for it to scan the SD card, and is extremely 'choppy' (low FPS) until this is complete. If I happen to accidentally bring up the keyboard during that 'choppy' period, it will remain on the screen until I do a hard reboot.
Anybody else experiencing something weird like that?

Good so far i even got locked on in the house in a room with no windows in like 5 seconds. First boot up after entering fix was real slow and had some quirks but now running normal. anybody else?
Thanks OP

no, nothing noticably different for me. Seems to boot normal. Even so Id rather wait one more minute on boot than not have gps.... I know your not complaining and it is valid im just saying. Even if this did have that effect im ok with it.

[settings]Fixed GPS with Cognition V2

Hey guys, Ive been having lots of issues with the gps actually locking on my phone, i know some of you have mixed results, but i was playing around with some settings and finally got a lock inside with 8 sats!
Below are the settings needed.
Getting into LBStest mode:
Then select SUPL/CP settings:
Server FQDN Type
Auto Config
Server: (This is the important one)
h-slp.mnc410.mcc310.pub.3gpp
Server port
7275
SUPL Secure Socket
Off
AGPS Mode
SUPL
I tried the same settings manually on my wifes phone with cognition 2.0 and it didnt work and the server port was a different number. I tried copying my settings over but it didnt work.
It looks like you need DG's cog v2.1
This worked great for me, hopefully it may help you guys out!
EDIT: picture is sitting on my couch 5 feet from a window!

I tried those same settings and saw 8-10 satellites too standing still.
Now set your navigation and take it for a test drive. It's still useless. (for me anyway).

i went from 5, to 8... lol so it was a small improvement.

I suggest you look at http://forum.xda-developers.com/showpost.php?p=8264844&postcount=1
SUPL servers provide ephemeris/almanac data which is usually good for 7 days. Changing wouldn't do much. It's usually a one shot thing. By default, the hardware GPS needs to get this information from the satellites themselves which good GPS units do in 45 seconds (SIRFIII) but I've seen bad ones take up to 30 minutes.

Same here.

It seems we need to start a thread where everyone posts their Lbstestmode settings and results to try and narrow down ONCE and FOR ALL which settings are the best.
More specifically, which settings are the best NOT ONLY for getting a GPS lock standing still in your home/apartment/office/wherever but most importantly while using Google Nav WHILE DRIVING!
In my opinion, getting a lock and going nuts over how many satellites your phone sees while standing still is pretty useless. I use my GPS primarily for navigation driving around town.
I've tried three completely different lbstestmode settings posted by different people in this forum, as well as the default Cognition 2.1 settings. All of them lock while driving, then lose the lock shortly after.

The issue is, at least for me and others as I have been reading, is that after the OTA update you can't get anymore into the Lbstestmode config with the dialstring.... Is there any other way to open/config that? I know this is not really Cognition related, since I guess with it you are still able to get in... probably will try it....

You can if you use LauncherPro. There's a walkthrough on here about it...but you basically create a homescreen shortcut to an activity and select LBSTestMode.

When you guys flashed the jh7 update, did you tibu your system settings and apps, or apps only? I did apps only and it fixed my GPS. I drove around, and even didn't follow the route, and it still found me consistently.

If you do some interweb reading you will see that most of the other phone manufacturers have an agps server. For the Deathstar it is: h-slp.mnc410.mcc310.pub.3gpp. In an almost universal rejection most are switched to a nokia server or to google's servers claiming faster locks and improved location awareness.

Meh - I've tried them all - can get GPS to work for a short period of time, then the device seems to die. I really think this is a hardware issue.

I think it is Hardware too. Only because I really have never seen any issues with my GPS running many different roms. I am a Field Technician so I am always driving around. I have been using my GPS when I go from site to site to see if I can find any real issues. It has stuttered from time to time, but not real big issues. Seems to skip for a second or two and then gets rigth back on track. Now each site isn't that far from each other about 10 to 20 miles so it may be that I haven't had a long enough trip to have any issues. I did go on one 100 mile trip the other day and it never quit on my. I am going on a 300 mile trip Sunday so will test it out the whole way and see what happens.

Thanks! That did the trick.... I see now that it still has the same values I had put in before AT&T's OTA update.... so I guess that wasn't touched by the update... makes me wonder... today I had way better reception and was actually able to drive from work to home without the signal dropping not even once... Only thing I did last evening was clear out all GPS data... so, now still on OTA JH7 and wondering if I should or not change that...

I have been thinking this too. Had gps issues with my first captivate, returned it because it kept shutting off. On my second one, no issues at all.

GPS Plus
Those having issues while driving, could you disable GPS Plus and post your results?
My settings:
Application Settings:
Session Type: Tracking
Test Mode: S/W Test
Operation Mode:MS Based
Start Mode: Hot Start
GPS Plus: Off
Dyn accuracy: On
Accuracy: 50
Use SkyHook: Off
Use PC Tool: Off
SUPL / CP Settings
ServerFQDN Type: Custom Config
Server: supl.nokia.com
Server Port: 7275
SUPL Secure Socket: Off
AGPS Mode: SUPL
With these settings I've been having great results, but I can only test in maps.
There is no navigation in Guatemala

Did samsung and sprint forget about the gps??? Wth!

Just pointing out, running a totally stock epic.
I can sit in FRIDAY TRAFFIC, like I did today.........and click on google maps... and even WITH WIRELESS NETWORKS ON.......my phone has NO FREAKIN CLUE where I am on the highway!!
After this fiasco with the gps, I don't think I'll ever be able to buy a samsung phone again.
Cold boot, warm boot, hot boot. Makes no FARKING DIFFERENCE when I'm sitting in traffic wanting another route at 5pm on a Friday after a week of work!
What a failure!

Ever think it was your phone? Mine locks within 5 seconds everytime even when I am indoors.
Wifi networks on
GPS on
Cold Start

Mine has a horrible time locating when I have 4G enabled. Here's my solution:
-Turn off 4G
-Turn on GPS
-Reboot
-Open Google Maps, boom sync right away.
-Turn on 4G after acquiring a lock if you need it

This is ridiculous for a flagship #1 rated phone.

Yes, there are bugs remaining with the Epic GPS -- some of which manifest themselves, or not, depending on usage patterns. The underlying problem is bad handling of the time-sensitive GPS cache.
As for your opening question: Did Samsung and Sprint forget about the GPS? That is a very good question. So far the manufacturer and carrier officially refuse to acknowledge the bugs. We know that Sprint investigated, and off-the-record third-tier support told a serious tester that the bugs were replicable and they forwarded the case to Samsung. Sprint front-line support, on its own forum, went through the motions of soliciting user' reports. But we never heard anything back.
There are workarounds for the worst of the GPS problems: Keep the Cold Start setting and turn off WiFi and 4G when initializing a GPS session with GPS Test. Then you can reenable 4g and use your mapping or nav apps normally.
But the GPS will not always work reliably out of the box unless Samsung fixes it.

I understand there are workarounds but the big problem I have is that Sprint completely ignores the problem. I've had an ongoing conversation with @sprintcare via twitter and every response is ignorant to the fact that there is a gps problem. They actually act like they've never heard of it and it's new to them when I bring it up. I pointed out that the Vibrant actually had an update specifically to fix the same problem. Generally, contacting @sprintcare actually works with most questions and problems, but anytime I ask about a gps fix their reply is "what gps problem?" then they continue to ask me questions about what gps app I'm using etc etc. I doubt we'll even be getting a gps fix for this phone.

All that is unhappily consistent with what I observe, with one factual distinction: The GPS bugs on the Epic are not the same as the GPS bugs on the Vibrant (or its GSM-based siblings, the Captivate and I9000). The Epic has different GPS hardware, different firmware and different GPS bugs. They are discrete problems that seem to be unique to the Sprint platform.

The Samsung Moment had well documented gps issues. My Evo never had a problem with gps and I had androids version and Sprint Navigation. Now the Epic has gps problems. Don't think it's sprint. It's the lovely Samsung.

Yes, it undoubtedly is Samsung's engineering problem to solve. But Sprint put its brand on the phone and sold it to us. Samsung built the phone to Sprint's specs, and presumably there was a QA acceptance step where Sprint signed off on the product before release. Part of the complaint in this thread is that the carrier is stonewalling in public about recognizing the GPS bug officially as a known issue.

Some kind of GPS update in Froyo beta
In the Froyo beta thread, it is reported that one of the GPS bugs -- the bogus estimate of 30-meter accuracy -- seems to be gone. So some kind of GPS update seems to be bundled with the Froyo release in the pipeline. No word yet on whether the more serious locking problem is fixed. It would take some controlled testing to determine that.

Might just be your phone.
Was playing with the updated Facebook app the other day and decided to try out the Places feature. I tried to check into a food spot I was having lunch in and the locations weren't loading. I realized that I turned off all location features, so went into settings and check on the locate with wireless networks setting and boom the location based services in FB started working.
Navigator and CoPilot Live all work for me and pinpoint in secs.

Having my droid next to the epic, my droid had 6 feet accuracy, locked on 9/9 satellites vs epic with incorrect 98 feet and 7/9
I'm sick of this crap. I love the phone so much, but this issue is getting to me. Idon't really mind as all phones have their problems, but it should have been fixed by now

Want to join our club of non-working GPS? Here's how: #1, tonight, before you goto bed, restart your phone. Give it a nice, full reboot. Then, turn on WiFi, and make sure WiFi is set to Never Sleep under advanced wifi properties. (When you go into WiFi settings, tap Menu, Advanced. Change Sleep Policy to "Never."). Now, have a nice night, dream in anticipation of your never-locking GPS when you awake.
When you awake (hopefully more than 4 hours after you went to bed), with WiFi still on, start Google Maps. What? The little GPS blinky icon won't stop blinking? And your location is a WiFi-inspired circle that won't quite lock down to your actual position? Welcome to the club, my friend.
How to fix? You can try what you like, but you'll have to shut off WiFi and reboot. Your ephemeris cache won't reset properly until you do. Sucks, doesn't it. This test is extensively-repeatable, and has been reported here, on BAW, and elsewhere.

What was the code to change gps settings?

This is my ONLY problem with the issue. I'm ok with there being an existing problem, and the cold start workaround works fine for me because I have great cell coverage in Orlando. Just show me you are working on a fix. Don't act like it doesn't exist, and as far as I can tell, that's exactly what Sprint is doing.

I think that's most people's grief. It's that there isa problem, and nothign has been done. it's a pretty big problem as these phones use GPS for alot of reasons

Not saying that the phone may not have a problem, but you are having a extra problem I think. Got to be the phone.
I use the piss out of my GPS, I'm new to DFW. I have to GPS everything here. Never have had a problem like that. I can't get enough of how smooth the google nav is.

Here's the best fix:
1.) Install Nero 4.1
2.) Leave it alone.
The end.
If that doesnt work:
1.) Install Nero 4.1
2.) Do the hardware fix
3.) Leave it alone.
The end.

my solution: get a new phone once a suitable 4" replacement comes out on t-mobile.

it works!
this by far is the best solution!
I get 10m accuracy now whereas i used to get 1200m before...

Let me try it a bit more, but it seems it works!

HOLY ****?
i got 10 satellites in 5 seconds, then they all started connecting and now my accuracy is 12 meters???

I think your all connected to wifi, maybe thats why your getting good locks. Disable it and try again.
Sent from my SGH-T959 using Tapatalk

I was out walking my dog this morning (no wifi) and while yes I was in a clearing, I turned on GPS Status for the first time since installing the new rom so it came up with the default html page explaining GPS Status, but I read it before so I closed it immediately and was already locked onto 8/11 birds. 2 seconds maybe. 7m accuracy.
On the flip side when I first got my phone I tried to use it as a GPS to navigate and drove around for 30 minutes without ever locking onto a single bird.
I understand and do believe there is a hardware problem with many Vibrants however I also believe that there has been a HUGE software problem as well.

I've been using OP's "fix" for 3 days and so far it's working very well. I typically get locks in 10s or less, and accuracy 15-30 ft, inside. I nearly always disable wi-fi when I test GPS, but I've tried it both ways with this setup and it's working virtually the same either way.
At this point my only reservation is I've seen so many similar suggestions to tweak some setting that don't really pan out over time. This one may do the same, but so far so good.

I have done nothing but installed axura rom.ine locks in couple of seconds and works flawllesly. Even the accuracy is fantastic.

My gps went from bad to worst, 600 metter accuracy, maybe its the rom, ill try teamwhiskey. i been crying for a working gps lately.

I had applied both the hardware and software fixes while using many versions of Nero and my GPS would never get quick locks, usually it wouldn't lock at all.
Flashing Axura fixed my GPS too. Locks within seconds and has 7-9 meter accuracy.
Axura also fixed my fiance's GPS (with no hardware fix). She had the same issues with every other rom, slow/no locks. So I know it wasn't only my device.
I don't know what method Devs4Android used to fix the GPS, but it works perfectly. They need to sell the fix to Samsung so customers can get functioning GPS out of the box.

never had a problem with the gps locking on to sats and getting 20-40 foot accuracy. the problem is the drifting and staying locked once you start moving or just standing there. that is the problem i have. driving down the highway and bam your on the other side going the wrong way, or in the middle of the field a mile away. that is problem i have

Thankfully, Axura fixed that for me as well. Not only does it lock fast, but its accurate too.

After 2 days.
Last 2 days, I've tested my GPS in some different scenarios. In every one it has been quick and accurate enough.
I got 8 satellites in average, and the accuracy was of around 7-8 meters, something that has never happened before. I did the hardware fix, and it helped with the SNR values, but this is the definite best solution yet!
I'm still testing, but I've got a very good feeling about this method.

The only difference I see between this "fix" and other "fixes" is changing the SUPL server to supl.nokia.com. Since the original thread came from a Chinese forum, I'm guessing the SUPL server might work well in China. Not sure how effective this would be in the US or other countries.
That said, this isn't really a fix. All it does is change the SUPL server, which for most of us (using supl.google.com) works just fine. The Cold Start -> Delete GPS Data -> Lock -> Hot Start method will work just once because it clears bad cached GPS data if you've moved, but it's old news (dozens of other threads on this one) and it's not really a "fix."
The hardware fix is still one of the few real fixes out there.

So I take it you haven't tried this. I agree with what you say, however, I've been using OP's suggested settings for 4 days and see a significant improvement in lock times (only exception is I leave it set to Coldstart). I've been turning my phone off at night and after booting yesterday morning it locked in 14s first time, this morning in 7s. I know lock times can vary depending on where the sats happen to be at that moment, but this performance is much better than I was getting previously, which was in the 1-4 min range on first lock of the day. It's so simple to try there's no real reason not to see if it helps, unless you're already getting lock times like this. Only time will tell if it lasts, but so far so good.
(Running pure stock JI6, and I've also done the HW fix posted in the sticky, which definitely improved my SNRs.)

Another GPS FIX...

This worked for me. Please post comments here in this thread about how it worked for you.
I just wanted to sort of repost this information that I feel I stumbled upon. There was an article on the XDA home page about a GPS fix for the GT-I9003.

My GPS was USELESS from day one. Sometimes half worked, other times you would have thought we were in a plane.
I tested my GPS just now before trying this and it found 12 Sats, only had signal on 3, and couldnt lock on any. I started with GPS Aid and all I did was:
Downloaded GPS Aids from the Marketplace.
Opened the App and went into GPS Aids
At the bottom clicked on "Download LTO"
I never changed any settings or any of what the OP said. I also never restarted my phone or anything. Just backed out of the app, opened up GPS Test and found 10 Sats, 5 Locked on with over 30 SNR, and 22ft Accuracy within about 2min. I have to wait until tomorrow to see it in action when I am driving, but things look promising.

thanks for sharing with us, will give it a try and will report back.

very impressed. clicking on thanks button

The only thing thats helping there is changing to supl.google.com port 7276
I've been saying it for months now that this is necessary, since the default supl server is actually offline. If you try hitting it from a browser you will even get one of those sites selling the domain.

Thank you!

I just tried mine last night while driving around at work(I cover a large area). Not only could I get a lock without a problem everywhere I went. But it actually showed me going ON THE ROAD let alone the right road. I could not get it to mess up. I turned SAT on and off a few diff times, restarted phone. The only thing that varied was the amount of time it took for the first lock. It still only took 5min at most and at one point I had 19ft accuracy.
so...YAY! My $600 "Smart Phone" can now do what a crackberry has been able to do for years and I found the fix on accident.
I tried everything in the "Vibrant Forum" and nothing worked. I had given up.I didnt think this was going to work because it was for a diff phone, but hey, I"m happy to know it helped people and appreciate all the "Thank You"

Funny thing is I never changed any of that. Mine is all still at default "www.spirent-lcs.com at port :7275"

If you try to go to any of those in a browser it says the same thing, damn some people ..... They wouldn't put a server in there as a stock server if it was offline you idiot. I'm sorry, I don't normally go at someone like this, but that was probably the dumbest statement I have heard in a very long time.

No, you are the one who is making a dumb statement. If you know what you are doing and try to hit supl.google.com on port 7276 it will show it is working as a supl server. Not so with the default one, there is simply nothing there but a placeholder, which means if you use it you are NOT accessing SUPL data for GPS assist. I've tested it on two vibrants side by side, the one on default would NOT access GPS data and thus took way longer to get a lock, until moved to a working SUPL server.
gg on your effort of turning XDA into the cess pit that its becoming.

no your statement was the dumbest for lashing out like that

My Telus Samsung Galaxy S Fascinate 3G+ (SGH-T959D) is supposedly to be a close bro to the T-mobile Vibrant.
====================== =============
GPS is a constant Not-Sure item on my phone.
Never know when it will/will not work. I was advised to up-plug/re-plug the battery when it failed.
After unpluging/repluging the battery, it has been working for the last 3 days as observed in the morning/noon running errands.
-- Using lbstestmode ; GPS status to monitor the status.
For supl/port, tried the values suggested, but found it would work just as well with:
* SUPL: Blank (typed in spaces; otherwise reverted to the factory value)
* Port: "7" (must have one value, otherwise reverted to the factory value)
-- Took about 5~10 minutes to see up to 10 satellites, and locking up (not all) satellites would seem requiring some sort of network connections (?)

UPDATE:
My GPS is still working. The only thing I notice is sometimes if I feel like its taking too long to lock on, I run GPS Aids and re download LTO. Then it locks instantly. But other than that it works great. I will def be donating/buying the Donate version of GPS Aids, it fixed my phone
