Obviously Samsung has no idea how to write proper drivers for Android phones running the QSC6085. I found a workaround that fixes any issues with GPS.
It's completely simple, turn off WiFi and 4G when you're trying to get a lock.
Proof 1: I stood outside in broad daylight with clear skies connected to my home's WiFi network. Using GPS Test, my phone discovered 12 satellites and made 0 connections for 3 minutes. I closed the app, disabled WiFi (used 3G) and I got a lock of 4 satellites within 15 seconds and 6 - 8 after another 15 seconds.
Proof 2: I left my house and went straight from WiFi to 4G. I got in the car and turned on Google Navigation. I set it to my destination and waited for a lock. After a minute I turned off 4G and got a lock within 15 seconds.
THIS PHONE HAS NO MAJOR GPS ISSUES. Obviously these are simple bugs and I have no doubt in my mind that Samsung is aware of these and will fix them in the next update.
Other GPS bugs I've noticed:
No matter how many satellites I have locked on, my accuracy has never gone below 30 meters.
SNR numbers are really low. According to a leaked ROM for the Vibrant, this can be fixed.
K.. I checked your tips..
3g only[Inside Apt] -- floats between 7 and 8 sat and usually 6-7 locks
Wify Only[Inside Apt] -- Solid 9 satalites and 7-8 locks
4G[no wifi] : stopped with 4 sat and 4 locks but I noticed that my 4g likes to sleep
Yes, it seems that when using WiFi, that updated ephemeris data is not being transmitted, however, it's not bulletproof - after a day or so, it'll try to lock, the 3G connection will go dormant, and it'll just sit there...
I have three epics and have been working with *#1472365# settings and testing for about a week.
I am concerned you maybe getting a false positive on repair of the main problem until you confirm, with no resets and further changes to *#1472365# (which reset the cache) that 24 hours later and in a diffident position you do lock most sats Epic sees.
There are a dozen things you can do to flush out the xtra data cache, just none that I have found that persist and to it regularly (ideally with a couple hours at most for ephmeris, and a day o r two for alamanc). Most proper aGPS implementation will also give the device a minute on warm/hot start, and if is seeing and not locking, grab new assistance data from the best source (first choice network, second birds)
I do think sammy is teid itself up in knots with drivers because of the many different agps environments Galaxy S is sold in. It goes way beyond GSM v CDMA, but also even bigger considerations, like agps data source adn methods, and even whether the device is in a unlimited data carier environment (like our epics) or not.
have you done any testing with the xtra settings themselves? seems to me that is where the rubber hits the road?.

The only change I've made with my phone's *#1472365# settings is setting it to Cold Start to save battery. I know in testing builds of the Moment aGPS addresses were set to internal testing ones that didn't work.
No problem with GPS here. I use Navigation and CoPilot and both pick me in seconds. Navigated from the mechanics workshop today just to test it out and worked like a charm. Guess some have it and some don't.
yes me too, and further, with speedtest app, the only way i can get it to lock on a server that is near me is to have wifi on when I start the app, then it locks on my server, otherwise, it has me 1500 miles away as closest server.

No, we all have the same bug and Sprint Device team is trying to get samsung on it.
You just haven't been in a condition where it occurs, whcih is turning on GPS in a different location say 8 hours later absent flushing the cache.
The Epic doesn't properly check the cache for staleness, so everyone who uses GPS will come up on this problem eventually. It is a bug Samsugn has had before.

the reason why I am asking is Epic has in that debug menu are setting to set time for attempts as well as flushing the cache manually. It would be interesting if we could get that going.
the reason I say so is cold start is a good workaround but it will murder GPS TTFF (time to first fix) in non network conditions. It will make it worse than standalone. Literally every time you start it will be a cold start and you will have to wait for almanac, which is 5 to 15 minutes if outside of network coverage. That is what I am seeing with cold workaround. I am still playings with forcing warm
Are you seeing that? with cold stat set, enable airplane mode, restart Epic, restart GPS and see what happens.

This method did not save me today, when after letting my Epic's GPS go unused for > 24 hours I tried to get a lock with WiFi and 4G disabled. Multiple satellites were visible, but only two were used. Gave up and rebooted. After which, almost immediately, I got 8 out of 9.

Yes I think the OP got hit with what hit us in all testing. That is why i am doing careful controlled tests. Since the main issue has to do with failure to consistently and properly remove expired and invalid assistance data cache lots of things may be removing that cache, for example any changes to that cause a reset.
Right now the only consistent way to remove it without user intervention is to go into the debug and set as cold start. The problem with that is it introduces a new problem affecting standalone TTFF, ie once you get outside of data range you will do worse TTFF than dedicated handlheld GPS units that keep almanac in ephemeris.
This problem is akin to some condition where the phone will freeze and not make calls if you don't use it in 24 hours but most people didn't realize there was a time consideration. 90% of the people would be saying there is no bug or that they have a fix.
to test any fix you have to:
get a gps location.
not use GPS for 12 hours or move location significantly.
do not reset or action that inadvertently fushes cache.
test again.
In every case and attempted workaroudn with this test but cold start hack I cannot get a gps fix on any of our three epics.
@aero1,
The complication in my last case is that I was in Cold Start mode. Maybe I just didn't give it enough time.

Cold start set in *#, data connection on, clear sky and no fix within 30 seconds? Please say it isn't so.

That's the setting alright. I think at first I had 4G enabled when I started GPS Test. But the first thing I did was disable it, thus defaulting to 3G, with GPS Test still running.
But it's possible I didn't give it enough time to lock. I was in my car and perhaps too impatient. I may have given up and rebooted after less time than that.
Since then I have left Cold Start set, and have not experienced a no-lock error condition again. But I have rebooted a couple of times for other reasons. When I started my commute home this afternoon and started GPS Test, it was slow to lock but it came around to a full lock in a minute or so.
I've been using the GPS quite a bit this past week. I've had no problems getting a fix except for onces. It was due to the typical bug (find satellites but not connect). I went into the GpsTest shortcut and set it to Hot Start then back to Cold Start. Immediately the GPS started working again.
Switching back and forth clears the GPS cache and fixes this issue. To me, that's the only problem this phone has. As far as I know, this can be an INCREDIBLY EASY fix if anyone can go into the source and put in a way to periodically clear the cache.
so i got my replacement bell vibrant after it bricked from 2.2.. this new phones gps does not work. ive tried several times outside with clear sky and all it does it finds a few satellites then drops them, over and over, never getting a lock.
should i open it up and try that bending the gps antenna contact trick? to me it does sound like the antenna is at fault here. its like its getting a really weak signal or something.
any ideas?

thanks. that seems to have done the trick. after it reset everything i was able to get 5 meter accuracy fairly quickly. and can even sometimes get a lock indoors, altho only 15-20 meters, but still, thats better than my old one
any ideas if the gps icon just doesn't come on at all / not function when i click the gps shortcut and it goes green like it ought to be on?
think this is only since root and/or flash to speedmod kernel k13e
It happens also on my phone sometimes. I'm running rooted stock firmware KC1. Just go out from the app that needs the gps and go in again. It usually activates it. I get this problem only with google maps. I think it's google maps app bug...
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!

Verified: after a fresh Odin of DK28 my GPS wouldn't lock, it just searched and searched... Reboot didn't help
History:
one.click.root.exploitv2.5.5.zip

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...

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
I received my phone yesterday and gps did just fine. I drained the battery and left it off while charging.
Today my gps won't work, I can't seem to get a single fix anymore (google maps, gps test, mytracks, nothing). I don't know what to do to fix it.
Also my battery drains extremely fast (5 hours and it's dead). Screen acounts for 63%.
I am having similar problems.
mainly with the GPS. it won't get a lock onto the satellites.
very dissappointing.
other than that it's a great phone.
hope it gets fixed with a firmware update soon!
Factory reset first step .
jje
Same problem here.
GPS sees like 10 satellites but just won't lock.
Factory reset does NOT solve the problem. rooted - not rooted does not fix the problem.
Me too, see like 10 satlellites but cant get it lock TT
Just curious, are you guys rooted now? Have been rooted before?
What firmware are you all running? i am on XWKDD. today i upgraded to XWKE1 but didn't have to a chance to see if it fixes the GPS issue just yet.
Same problem here, sometimes I have 10 satellites but it just won't get a fix, no root here.
I get a fix within a few seconds of firing up the GPS, every time.
Even in my rucksack the GPS tracked me for an hour and a half, within a few metres accuracy, whilst cycling a few days ago, no problem.

I assume you're trying this outside without major obstructions around.
I would turn off: wifi, "Use wireless networks", and "Use sensor aiding". Run GPS Status. Under Settings > Tools > Manage A-GPS state, press Reset, then Download.
See if that helps.

I don't know anything more than the description it shows under Settings. I've seen theories that it uses the accelerometer, say for instance if you're driving through a tunnel. My experience is it makes my GPS accuracy worse rather than better, so I don't use it. But I'd suggest trying it both ways on the S2 to see if it makes a difference.
I went here:
http://www.google.com/mobile/navigation/
did a search on "sensor aiding" and got zero hits, so it seems Google doesn't want us to know what it is either.
usually over 50% of what people reporting that it isn't working is down to user error.
Have a look at this vid and do what this guy does on his SGS II. And see if it works for you

So, is that the new normal with your phone? Are locks working faster now, or do they typically take minutes? Is the accuracy ok?
It is odd that there are such differences between individual phones. If problems continue I would get it replaced if possible.

Having problems here too. tested today on the way to the supermarket, got a lock within a couple of minutes and worked fine for the duration of the journey. Didn't get a lock all the way back, GPS was definitely turned on, even stopped halfway home to reboot the phone and try again.
Just taken my wife's iPhone 4 outside which locked within 30 seconds, still can't get a lock at all with my GS2.
I've installed that GPS status application, but doesn't lock on to any satellites (at least not within two or three minutes anyway)

Forget Apple, if you want "real results" grab a Nokia E-Series like the e71 or e72.
You get like 2 second instant lock, and that's indoors!...

This thread, and posts like this, are what make me so frustrated with Samsung over the GPS issue. They never fixed the SGS, and now with their flagship top-of-the-heap phone they still can't get it consistently right. Even the best reports I've seen on the S2 don't match what some other phones are clearly capable of. It's hard to imagine Samsung is truly technically incapable of making GPS work, so I have to conclude it's just not worth the cost to them. They sold 14 million SGS's, with abysmal GPS, so they've apparently decided most don't care if it works well or not. They may be right, but for some of us it's one of the absolute key features. Very disappointing. Maybe HTC will get it right on the Sensation...
So I the only thread I found on this was really old with no resolution so I'm starting a new one.
My gps will show like 0/24 on gps status immediately and not fix any. Earlier I got 2 satellites to fix ad that was all. This is outside in my car with a clear view of the sky. has anyone had any luck fixing gps issues?

Are you using the GPS Status app (developer MobiWIA)? I ask since that app allows you to add all the extra details in the notification bar while the GPS is searching for a lock. If so, have you tried getting a GPS lock in any other app (like Maps)? I can get a lock in all my other apps, as well as other GPS diagnostic app EXCEPT for the one developed by MobiWIA for some reason. I keep it installed though as I like to see the status in the notification bar.
I'd suggest downloading the GPS Status app if you already don't have it (the MobiWIA one), and go into Menu > Tools and click on Manage A-GPS State. Then click on Clear Cached GPS Data. Then click on the button that says Download Additional Files (well, says something similar to that). Then open up a different app and see if you can get a lock. I had to clear my GPS data and download those additional files before I could get a timely lock as well, but now I get a lock within 10 seconds while inside the house. This assumes that you haven't rooted tour phone. If you're rooted, you can do all this (and more) manually. Just clear GPS Cache and Data, and open up /system/etc/gps.conf to add any additional servers to the list, as well as tweak other GPS setting.
ya i tried those before, it's acting even dumber now, the top bad with the gps icon is solid indicating a lock. However any gps status app that I use will show no satellites locked. I get it to lock a couple after sitting there for a while on gps status sometimes though but its really shady
My past g2 did that, I returned it. Got a replacement, afraid to even root this beast.

so after you replaced it the problem was solved?
Same issue. The GPS on this phone sucks. It'll be 4 miles off sometimes and that's even if I can get it to lock.

Looks like the Verizon G2's GPS reception was compromised with the addition of wireless charging. T-mobile D801 here and I get a lock within a few seconds indoors.

Nope, still as ****ty as ever.
Although it doesn't happen as often, it still more often than others.
I'm past the remorse period.
So yeah.
Here's one from yesterday where I needed to get directions while driving, it locked but didn't do jack ****.

Well I guess atleast that means it most likely isn't completely hardware related.
Mine (T-Mobile) locks in just a few seconds, even indoors!
I always have data on, so it makes the process even faster (A-GPS makes use of the cellular antennas to acquire a lock faster). It works really well actually. I have at times the GPS off and even then, my location gets pin-pointed very quickly!
Cheers!
I have the GPS lock issue sometimes. What I have found to work for me is I turn airplane mode on let it sit for a second, then turn airplane mode off. By the time airplane mode is off and BT, LTE/CMDA signal notification are coming back to life my GPS has a lock and is working like it should.
YMMV on this, but it does work for me.
