JI2:Enable MS-Based mode for a faster lock

For me, my GPS problems have been mostly fixed with the latest firmware.. however the lock still takes about 15 seconds.
To enhance (not fix, it's not a fix) this..
Install AnyCut (not in the market for some reason), select "new shortcut" and go down to LbsTestMode.
Open it, select MS-Based mode and back out of it. Don't change anything else as you're liable to make GPS worse.
Now you should get a lock in 1-3 seconds, very quickly. If your phone is not getting a lock disable WiFi.

And much better tracking as well. My Tracks did much better when I turned it off standalone to MS Assisted.

wow. First lock after flash was great, then after the days go it gets worse, basically back to before. Changing this, I opened my front door, pointed the phone out, turned on gps and opened gps test. Instantly like 5 seconds I got 6 satellite locks.
Awesome, obviously will see after a few days how it works. So far that helped alot.

It's never gone to what it was like before (ever) but I've noticed some bugginess with aGPS.
Over WiFi it won't download new information & lock. I've had to disable WiFi for it to lock on a position.
Sometimes when going from 3G to E, it will lose the lock. Is this horrible? No. Can it be corrected? Yes.. can the Vibrant accurately track our location? Yes.
MS-Assisted is only good for stationary locks quick one time fixes but not actual tracking. MS-Based is for tracking..

Could not get a lock on MS Based. It saw 6 sats and they were all at the same position way off the compass on GPS status. Let it run for 10 minutes on 3g and it lost all but 2 sats. Change it back to MS Assisted and I get 10/10. Maybe I need to clear data.

At this point I am pretty sure that the settings in lbstestmode only affect the tests in lbstestmode. All other applications appear to use the settings in gps.conf or somewhere else.
Changing the settings in lbstestmode appears to affect other apps temporarily due to hot start mode but after reset the phones are going back to default anyway.

Well you can test it yourself. It's too soon to say much of anything. It takes time to determine anything with this phone. If nothing changes it will be noted in a day or two when the hot fix is lost.

Yeah it is just plain buggy. Sometimes lbstestmode seems to change gps.conf but not always. The use SSL setting doesn't seem to be changed but sometimes it does change the SUPL host.
Another strange things in test mode is turning on MS Based and then clearing GPS data. Sometimes when I do that and then run the get position test I can see my 3G turns on and it pulls the list of satellites. 10 satellites found in a couple seconds...great. If I then go back and clear the GPS test data again and go back to the same test it sits at zero satellites and never pulls a new list. WTF...completely unpredictable behavior....sigh.

Just drove about 5 miles. Locked instantly and very well.

3x GPS for Vibrant fixed for J16 & Froyo Azura **Added Videos**

Hey everyone.
I managed to finally get GPS to lock quickly, indoors.
I'm an advanced user, and i've done everything from upgrading to j16, going back, trying all the different settings, going to Froyo, mods, and back etc....all of which did not work.
Note, I had an N95 -> N86 Nokia phone which ALWAYS locked on (aGPS) in less than 5 seconds, always. So you understand my major disappointment with Samsung with its failure to lock within seconds.
These are my steps:
1) Followed the steps as posted by digitaltoddy:
You'll need to get into LBSTestMode by entering *#3214789650# from the dialer. Press Delete GPS Data, this will get rid of the bad GPS information that is probably still stored in your phone. Go to Application Settings and set the Start Mode to 'Cold Start'. Reboot your phone and go outside, run an app like GPS Test and let it lock onto as many birds as it can, once you get a good number (at least 5), go back into your LBSTestMode --> Application Settings and set the Start Mode back to 'Hot Start', reboot and all should be merry.
2) After the restart, get back into LBSTestMode and change the Server FQDN Type to "Auto Config." I've tried this with Custom Config with the stock server (spirent-lcs) and google server (supl.google). Auto config works about 2000% better.
My Test Procedure: (Indoors!)
1) Get into LBSTestMode (*#3214789650#)
2) Delete GPS Data
3) Set to "Cold Start"
4) Reboot Phone (Removal of battery)
5) Get into LBSTestMode (*#3214789650#)
6) Do position test
To note: I used digitaltoddy's method and was unable to get desirable results for 3 phones. So I can't be sure whether his method, or that the Server was set to Auto Config which fixes the GPS.
I'm posting up a YouTube video now, but I don't think I can link it up because i'm a noob on this forum . On the video, I show how quickly it locks on "Auto Config" indoors
Good luck.
1st Vibrant -> JI6
2nd Vibrant -> Froyo Azura (YouTube video)
3rd Vibrant -> JI6

If one/both of these doesn't fix someone's GPS, then that someone is a liar. +1 to you sir

bookmarked for future reference!

I posted two new videos to prove my findings.
You can see in the video, when put into "Custom Config," nothing appears for a long time. If you wait longer, you'll get one or two satellites - thus showing that aGPS isn't working.
I turned it to the "Auto Config", and an entire list of 11-12 satellites showed up in a matter of seconds, locking in 32 seconds.
I have tried supl.google.com 7276 and it too, doesn't work. Try it for yourself

AGPS is dependent on the network to work properly and IS NOT TRUE GPS! If you can't get GPS to work in standalone then it isn't a fix, simple as that.

Dude.
Its clear that the aGPS function on the phone itself DOESN'T work on Custom Config, and does on Auto Config as shown in the video.
My locking time was brought down from 5-15 minutes to 30 seconds. How is that not a fix?

aGPS won't work if you don't have data.

Yes, AGPS requires data while standalone allows the GPS to in airplane mode. I know this because I use maps from my SD while in that mode. There's also no such thing as J ONE SIX. It's J EYE SIX.

so the GPS problem is finally resolved?

aGPS will work with data. If you don't have data, use GPS code newer than JKF and do the LBSTestMode thing and it will work. Not new information

For some reason I can't change the config back to auto? It's greyed out and set to custom config...

did not worked for me... only ROM I'm able to get a fix is with Macnut R10,, any other ROM and my GPS is worthless

did not work for me either. I stood out in the freezing rain for 10 mins and no lockons... had 8 in view after 3-4 mins but would not lock on...

Since when has there been a problem with the standalone GPS?
The aGPS has always been the culprit on this phone. When aGPS is disabled, it's worked fine.

Here is my comparison:
1. Auto Config - initial lock in 145-178 seconds with 45 meters accuracy.
2. Supl.google.com - initial lock in 4 seconds and lock on 9 out of 11 satellites with 5 meter accuracy in 30-40 seconds.

I appreciate the post and glad it helped for some, but no luck for me. I went throught the entire process, also spent about 10-15 minutes standing in poor weather, finally got a lock on 5 satellites.
I decided on a real world test this morning and used my GPS to navigate me to work. I have a short commute, only about 10 minutes, less than 10 miles. The GPS lost track of my position numerous times, had me on side streets, off the freeway, all over the place. In short, it's the same problem I've had all along...before JI6, after JI6 and after trying the fix noted in this post.
I love this phone, but the GPS sucks ass.

There's always been a problem with the gps on this phone. Fixing agps as the op does here helps work around the poor gps initial locking performance, but the core accuracy issues remain, as are evidenced by the horrible tracks produced by this device.

Hey Krzysiek,
Thanks for your comparison. Strange, on my 3 phones, setting it to Custom did not work at all. Did you set it to Cold Start and clear the GPS data before you did the test?
Thanks

easiest way to fix gps using DK28

Searching in internet for the easiest way to fix my gps after updating to DK28...I came across with the following instructions from user WorldWide (pcgeek forum):
"Fixing the GPS no fix issue on the Samsung Epic 4g requires you to do a manufacturer's reset by obtaining the MSL code from Sprint. Once you get the MSL Code, remove the SD Card and Enter ##786# on the dialer keypad. You will see two options: View and Reset. Tap on the Reset option and you will get a prompt to enter the MSL code. At this point you will be asked if you want to do a manufacter's reset, enter yes. The phone will shut down and reset itself after a few seconds. Once the process is complete, the phone will go through a hands free activation. After the activation process, updates may be downloaded and installed. Now that all updates have been performed, you may check to see if your GPS is working by going to Google Maps. You should be able to lock in GPS signal in under 10 seconds. Thats it. Your GPS woes are over."

I followed the instructions above and my GPS is working perfect now.
ps: make sure you back up all your applications before doing it.

Strange, I've never had any problems with GPS and dk28.

mine stopped working after updating to DK28 ...but I followed the instructions above and now is fine

Here is my GPS issue
So here is my GPS issue, and I don't recall seeing anyone else have one like it.
I can get a fix SUPER fast, no problem. My phone always seems to know where I am when I need it to, to do a search or whatever. It is accurate too, down to 10's (20-50) of feet indoors, even better outside.
What doesn't work well for me is navigation. Google nav and also sprint nav. I load either one up, select a place to go, and everything seems fine. It starts navigating pretty quickly, because like I said getting a GPS fix almost never takes more than a few seconds on my phone. But after a few minutes of navigation, it stops tracking me. It says GPS signal lost. Then after a short period of time, at least in google navigation, it will zoom out and show me somewhere in the vicinity of where I actually am with a huge blue circle around me. Then it will zoom in more accurately, and finally start navigating again right where I actually am. But eventually it will stop again and go through that whole process. It does this OVER and OVER. I have seen the rare instance where it works fine for the entire trip, but 99% of the time that is not the case.
So my question is, is this a DK28 issue or something? I don't recall seeing this on DI18, but to be honest I was only on DI18 for a very short period of time so maybe I'm wrong about that. Is it a hardware issue?
If I have just google maps open the little blue dot will follow me all over the place and it never seems to have an issue. If I have GPS status open, it never seems to indicate that suddenly it can't see any satellites.
I've used the LBStestmode to check the GPS settings:
Session Type is Tracking
Test Mode is S/W Test
Operation Mode is Standalone
Start Mode is Hot start
GPS Plus is ON
Dynamic Accuracy is ON
Accuracy is 50
GPS Logging is OFF
I changed the SUPL server to supl.google.com and the port to 7276, but no real changes were noticed. SUPL secure socket is OFF, and AGPS mode is SUPL. Server FQDN Type is Custom Config.
Any help would be appreciated.
I'm running Nebula ROM 1.0.6, ext4 mod with no journaling.

That is very common. To me and I have seen it hapen to others. It is known that the GPS chip is weak. You obstruct its view by even a mere hand and signal lost. A quick fix is to pull down the notify bar. Toggle the GPS button, andyou are back in business immediately. Oddly enuff, I do not have this problem on ViperROM only.

I've got the same problem. Before I went to DK28 I followed the process of Odin back to DI18 to get GPS lock before upgrading (so as not to take any chances). I didn't have any GPS problems on DK28 with Quantum 2.5 (even on a 20 hour long road trip)
However, after I upgraded to Quantum 2.7 this behavior you described began happening to me. When it loses GPS it tries to approximate your location by network (hence the big blue circle).
I think Dameon indicated he included a "fix" in 2.7 for GPS issues which might cause this behavior. I flashed Bonsai to see if it behaved the same, and it appears to.
OP thanks for sharing. I'll test this tonight when I'm travelling again. I can't reproduce the GPS issues sitting still in my office.
Also, to get your MSL without contacting Sprint go to command line (via ADB shell, Terminal Emulator, ConnectBot:localhost, etc) and type getprop - look for line ril.MSL.

If you search the original issues you will find that only removing the battery will fix the problem. I never noticed the gps cache problem becase I replace my batteries 2-3 times a day.

I had issues with the cache bug on the Eclair builds, but it is no longer present since using the dk17 and dk28 modems.

I tried this just to try it (did a nandroid backup prior) and the phone would NOT activate after this reset.
I had to go back down to 2.1 di18 and it failed the activation as well however, launching the sprint self service right after activated the phone for me.
So... becareful guys when doing this, may not work right for everyone.

Thanks for the warning. However, it worked for me okay.
I just did the reset. It activated for me afterwards. The phone app did FC but after closing it came back up the and activated just fine. Also auto-updated PRL for me! Forced reboot after activation, everything looks good. Restore data, good so far!
I'll try the GPS Nav to see if it drops on the way home tonight.

Actually give credit to the user NYCSUBWAYRAT for this method I just quoted his post on androidcentral. My phone did not self activate the first time I tried it, I went into SprintZone and it activated from there. I tried it again a few days later, and it activated automatically.

Working good so far!

DK28 via Odin sph-d700-dk28-8g-rel.tar.md5
My steps: (I forgot to remove the sd card, but lost no data)
1) Call Sprint and ask for the MSL code
2) Backup everything from ClockworkMod
3) Dial ##786#
4) Choose "Reset"
5) Enter MSL code
Results:
The phone rebooted twice, then updated the PRL.
It tried to update the software but got stuck (I hit the back button to cancel it)
No prompt for activation, as Sprint phone rep had said.
Tested the GPS - rainbows and unicorns everywhere.
This beats the old GPS fix method: Odin back to DI18 then DK28 again...

thanks sooooooo much.

Also, you can get MSL code without calling Sprint using ConnectBot (from Market)
Run ConnectBot, in dropdown menu in lower left corner select "Local"
Type in any name in the nickname box
Type "getprop" (no quotations) then hit enter
scroll up in the results (ril.MSL) is the MSL code

To anyone having gps issues

To help most people with gps locking issues
1) download gps status from the market
2) turn gps on
3) open gps status
4) hit menu button, tools, manage a-gps state, then select reset
5) hit menu botton, tools, manage a-gps state, then select download
6) give the phone a clear view of the sky, when you get signal you will see the middle row fill with info and satellites in green on the bottom.. Back out and open gps app of choice.

Thanks to j32driver!
3. modify /etc/gps.conf entry (requires root/temp root) changing NTP_SERVER=north-america.pool.ntp.org to NTP_SERVER=us.pool.ntp.org.

Thanks to calebv2!
Sadly, these fixes will not fix issues related to bad satellite coverage/visibility/interference. And won't fix EC09 fried SD cards, either.

Thanks for all the links and help here. My GPS has always been sub par. While it will still not lock on when I'm in my living room, it gives me fairly accurate locks when outside.

Glad to see this helped people.. For really stubborn gps locks, follow my original instructions after a fresh boot.

Bingo. I had updated to ED01 and was getting nuthin' at all from the GPS. Did the reset/update AGPS, adjusted the NTP server, and within 5 seconds or so had 8+ satellites and 14-foot accuracy. Sweet.

I had tried all listed suggestions above and still could not get a lock without a 2+ minute delay (and only using GPS Status could i finally get a lock)
I updated my radio to EC09 last night and Instant GPS!!
So excited about that I can even pull GPS without cell signal which i have never been able to do before.

Editing the GPS.conf work perfectly. I went from no locks to locking in 2-3 seconds.

as soon as vzw comes out with a dual core lte that i like, i will dump my fassy bc of the gps lock issue. i have tried every "fix" i could find since i got the phone over 1 year ago, and still have issues. whats odd is that i can have a perfect lock and use gps to arrive at a destination, but when i leave the building cant reaquire! sometimes a battery pull solves the problem, sometimes just 20+ min of waiting. uggg!

Helped me !!!
took just 1 minute in total LOL.
god bless mate .

I now use "gps aids" from market.. It seems to work little better.. Next time im at a computer I'll update op

The GPS.conf thing, I looked in mine and I have:
NTP_SERVER=us.pool.ntp.org
NTP_SERVER=north-america.pool.ntp.org
NTP_SERVER=0.north-america.pool.ntp.org
NTP_SERVER=1.north-america.pool.ntp.org
NTP_SERVER=2.north-america.pool.ntp.org
NTP_SERVER=3.north-america.pool.ntp.org
so do I win?

Gps booster from market works wonders

GPS finally working again!

I couldn't reply in the developers area because I haven't posted enough, but wanted to say thanks to Raptorseye for the following:
"download gps status in market, run it, wait till it locks, then you can use your gps/maps..."
Ever since I moved to Gingerbread I've tried everything to get my GPS to work again with no luck. I've tried the ACS GPS fix, I tried remounting the file system and modifying the permissions, I've tried going back to an ec05 rom, and also swapped out the ec05 modem and ee03 modem.
But by running the gps status application from the market as recommended and letting it sit there for about 8 minutes, it finally locked on to over 5 satellites indoors. I was able to then run other gps apps and they worked.
Unfortunately, you have to repeat the connection to the satellites every once in a while using the gps status app.

There's a setting for gps status to download a gps data every hour if u want it to. In gps status click menu tools manage a gps state. Clear the do it again and click download. But as I said in the settings you can have It download assistance data every day or even every hour. Open gps status push menu settings. Gps and sensors. Then auto- download agps data and set it too what u want.

I too use GPS status, but it does take a long time. For me, the quickest solution is to power down, pull the battery and reboot. Takes less than 8 mins (which might be important if you're trying to get somewhere!) and you'll get a virtually instant lock when you go back to your favorite nav app.
Here's to hoping this gets fixed in GB!

This means you're not getting the ephemeris (Xtra) assistance data on boot, or at least it's not being used.
Are you able to get fixes faster using the Settings -> Update AGPS option in GPS Test? GPS Status has a similar option, but that may crash the GPS if the crash bug hasn't been addressed in EE03.

Does an assistance update from GPS Test help here? Or does only a reboot fix it?

It does not take a reboot to work for me. I just reset a gps then download agps assistance. And close gps status and I lock fast every time. Of course as I said I have it set too download assistance data every hour

The assistance data is supposed to be valid for a whole week, so it shouldn't have to be done more often than that. Although it wouldn't surprise me if it needs to be.
I am curious as to how often folks find themselves needing to update assitance data. Once a day? Once every few hours? Last time we looked into this there wasn't a clear answer.

Hm, never have used GPS Test, but I have it installed now and will give it a shot the next time it gets hung trying to get a lock.
The cold boot wasn't my idea, but I heard it mentioned on here months back. I was getting late for an appointment, so I figured, what the heck, i'd give it a shot. The OP mentioned that the battery-pull method is the only way to really clear the GPS, and I'll be darned if it didn't work. It's solved the problem every time I've run into it. I'll be sure to give GPS Test a run and see what happens.
Thanks!

I have been plagued by the no lock/10 minute lock. GPS status didn't help. None of the patches have helped, in the long run...so I just down loaded GPStest Plus, the newest one, and it seems to do the trick. Instant lock the first time out. Tried again a few hours later and nothing after a few minutes so I reset and redownloaded agps and bam, locked within seconds. Will try again in an hour when I usually would not get a lock or a very, very slow lock and see how it goes.
