Does anyone know of a utility to reset the internal GPS completely?
I use location-based tools all the time, and this annoying GPS failure in EC05 is a real PITA.
I know some folks have had some luck doing a "cold start" using the GPS Status utility, but this has not worked for me.
Symptoms are that the GPS works fine for a while, then loses lock. Going into GPS status reveals no satellites visible at all, and the GPS icon on the notification bar is gone..
Using Menu/Tools/Manage A-GPS state I have tried both reseting the state (cold start) and downloading assistance data. Turning the GPS off and on again also does nothing. OTOH, if I simply reboot the phone, the GPS comes back right away.
Many have reported this issue was fixed in EB13, but came back in EC05. I'm running SRF 1.1 right now, but I also had this problem in the stock EC05 that I received OTA.
Having the GPS just work properly all the time would be ideal. But short of that, being able to restart it from scratch without having to reboot the phone would be an acceptable workaround. Even a command-line utility would be better than nothing.

It's aggravating... I have the issue and I too am waiting for some kind of fix/workaround.
I use my GPS at my evening job pretty extensively. I suffered from this issue on DI18 ROMs daily, but I haven't experienced it yet since the dk17 froyo beta.
Exact same problems here. I am on Bonsai 4 but have also had the same problem with all the other EC05 roms I've flashed and the stock EC05. It was fantastic while it was working in EB13.

To those still having this issue, what method did you use to get to EC05?
It came back in ec05 because people didn't use the fixes we used in going from di18 > dk28 > eb13. Search these threads and do what we did and you won't have the problem either.

I was on whatever the stock Eclair release was out of the box -- bought the phone literally the day after Sprint suspended the EB13 OTA rollout.
I got EC05 pushed to me OTA a month later. GPS had the same issue on Eclair and EC05.
To get from the OTA EC05 to SRF I had to Odin back to EB13, but I only had EB13 on the phone for a few minutes -- did not test the GPS behavior.

I've tried a few things.. but at present, I went back to stock Eclair through Odin, then took the OTA to EC05.
Basically, I installed clean, so it's a mystery to me why others don't have this. Actually I think quite a few do, but haven't realized it yet... because the first time you get a fix after boot, it works magnificently well... 3-10 seconds. Great.
It's the down time after that, the hours that pass after that first fix that seems to change things. Without doing anything specific, just using the browser and other things.. the ability to AGAIN get a fix is hindered. Sometimes the GPS doesn't get one at all.
I'll let all the smart guys work on this one. I'm just a competent end user with no real knowledge of how the GPS works.
Just wanted to chime in..
I was waiting for someone to bring up this issue. Symptoms identical to OP's. Stock eclair worked perfectly, and this problem appeared in eb13, after a manual update. Ec05 did not change a thing and Gps status cold start did not help either.
This sucks since I use gps all the time.

As I noted above, I'm not a real gifted technician.. but I'm guessing this issue has something to do with the internal compass. I noticed that my two co-workers who both bought the Epic based on their favorable impressions of my phone, had issues with screen rotation after going from stock Eclair to EC05. Neither are advanced users. Neither rooted or otherwise messed with their phones. I too have tinkered with the compass.. the upside-down calibration and the terminal command pertaining to Yamaha.
I can effect the quality and time of the fix by waving the phone in a figure eight pattern in an attempt to calibrate.. so I'm thinking it's all related.
Running SFR 1.1.0 and I haven't experienced this yet. Took a three hour walk yesterday and CardioTrainer locked me the entire time even through the trails.
How long does it usually take for GPS to lose lock?
If it matters, I only enable GPS, not network-based location.

On DI18 based ROM's, the GPS data cache would not flush itself properly and you would lose GPS functionality usually within hours after it seemed to be working fine. My evening job I work as a delivery driver, and I would have to reboot my phone a couple times a night because of this bug. But as I stated earlier in this thread, I have not experienced this bug since dk17. I did experience some issues in DK28 where the GPS signal would drop out for a few seconds here and there, but since EB13, it's been perfect. No issues. My other Epic is stock EC05, so I will run some tests with that one tonight to see if I can get it to foul up.
So is anyone running Bonsai 4 experiencing this problem at all?
My understanding is that Bonsai uses an EB13-based kernel with only select EC05 elements, so perhaps it is not prone to this issue. If that's the case, that may be enough to make me switch to Bonsai from SRF.
It would also appear that the problem is not universal across all EC05 (and EC05-based ROM) users, as there have been several reports in this and other threads from people with no GPS problems at all. This makes me wonder, among other things, whether or not some specific app or module is either causing (or clearing?) the problem. Since lots of folks on stock OTA have the issue, that would likely be an OEM app.
This problem is a real PITA for me as I use the GPS all the time. Really, really want to find a solution.

If you just want to reset your GPS cache data, there is an onboard utility invoked by a dialer code. Open your phone dialer and punch in
##GPSCLRX#
That opens a dialog that requires you to key in the MSL code for your phone. Normally the Sprint support desk has to give this to you. (If they do, write it down for future use.) There are other methods to find the MSL, including this one.

Thanks, I have the MSL. I've also now placed a shortcut on the home screen directly to this utility, which actually bypasses the MSL. From Launcher Pro, long press on a blank area then select Shortcuts/Activities/com.android.hiddenmenu/GPSCLRX.
We'll see if using this GPSCLRX utility brings the GPS back to life next time it locks up.
While I am on the hiddenmenu subject, does anyone know which module is the GPSsetup utility? Supposedly this ships with the phone, and was previously (pre-Froyo) invoked with the dialer code *#1472365# but, according to threads on some other Galaxy-S forums, Samsung changed the code due to customer abuse. The alleged replacement code does not work for me, and I've tried all the obvious modules in hiddenmenu with no success.
In the interim, I've flashed LBSTestMode, which seems to work fine for reading and testing the GPS chipset, but is purportedly for a different chipset and so it is not clear if it can actually change settings (see androidforums.com/samsung-epic-4g/308885-gps-aquistion-ec05.html).

I could not find anything. The only Activity I saw with GPS in the name was the aforementioned GPSCLRX. However I should note that I am on SRF 1.1.0, and it is possible that K0nane removed this module from the ROM. Does anyone know if it is in the stock EC05 build? Also, what's the .apk named, so I can try to find it and load it?
-Sean
Is anyone else noticing erratic characteristics from the compass while getting a GPS lock with GPS Status/Toolbox?
Can this be one of the problems contributing to my horrible battery life in MidNIGHT 6.0?
In my defense, I did do some searching, both google and within XDA before i posted...
TIA!
Huta
so i guess it's just me then... hmm
Gps is not as accurate for me as well but it still works. The battery problem is most likely the cpu always being used around 35%.

I've had the same issue with mine, I initially was on EC05 stock with CWM 3.0.2.5 then flashed "Swiss Cheese Samsprint" ACS EE03 ROM, and Odin the Modem to EE03 which broke my GPS, I flashed the ACS EE03 GPS Fix, and I get that same icon but no GPS lock, I figured it was the ROM but same thing happened on Midnight ROM 6.0 and also on Gingered 0.07. I stayed at Gingered 0.07 which is basically a combo of Swiss Cheese and Midnight. I probably could get it to work if i downgraded modem and rom back to ec05 stock and lock gps signal before i flash the EE03 modem but im lazy, I dont use GPS all that much anyway.
I am currently using Midnight 6.0, and I have GPS issues, but my battery life is great.
My compass has ALWAYS been essentially useless. Once in a while I can get it calibrated so its KINDA accurate (I'd hate to be lost with the thing and actually NEED to use it, it'd be useless), but I've never had it working well.
As far as GPS goes, I've had it be pretty good when it works (SFR 1.1.0, now 1.1.1) although there was a "crashing" issue where you'd have to relaunch navigation to get it to reinitialize. That being said, 1.1.1 has a fix to prevent this (still testing, seems good so far).
One thing I noticed which I find very interesting. The EE03 Gingerbread leak gave me THE MOST AMAZING GPS PERFORMANCE EVER. I couldn't believe it was the same phone. Immediate locks, never lost a lock (even under a bridge!). That's with both ROM and Modem on EE03. Compass still seemed screwed, which is a damn shame (because it makes me think its just crappy hardware that will never be fixed.
As much as I love this phone, seriously, it's like 9 months since release and we're JUST NOW getting GPS to work right? I love our devs, and they seem to make much better headway but jesus christ, how bad is samsung at their job that a) we're still talking about this bug in STOCK roms 9 months later and b) we clearly have evidence that it CAN be fixed (problems not in hardware).
Now I have a very difficult decision to make. Do I get the Evo3D with potentially terrible battery life (my mom's thunderbolt only lasted til 1pm basic phone/sms) and mediocre camera, or do I try out the S2 hoping samsung's learned their lesson...
Still nothing...
I have tried all 3 Leaked Gingerbread ROMs. I tried the acs ee03 modem + gps fix, with everyone of them. I'm still getting no GPS signal. The icon blinks on the bar! the phone recognizes a signal, I no longer get the warning after I install "the fix" but it still constantly searches in Navigation or any other App. Has anyone figured anything out?

Yeah i forgot who quoted this, but i remember someone saying they opened up google maps after Odin'ing the EC05 Stock rom THEN they flashed everything else, EE03 Modem last. That worked for me, however i still have the funkified compass, even MyTracks cant correctly orient me when I'm jogging, despite knowing my location by 3 meters.
http://forum.xda-developers.com/showthread.php?t=1099041
couple threads down from yours... its basically the GPS fix for DK28... start at stock ec05, get a lock, root, get a lock, odin modem, get a lock, flash any of the ee03 ROMs... should get a lock. As far as the compass goes, not sure. Get spare parts, do wifi sleep never or at least never while plugged... maybe resort to juice defender for now... theres only so much the wizards can do without source.
Try the upside down calibration (menu/settings/display/Horizontal Calibration) before giving up on the compass. For some reason, since Froyo, the pitch axis came up -180 degrees.
This is how to fix your gps.

This nice fellow wrote a post on how to fix the gps problem:

Hello,
I am running EF02, I odined it, and I just found a huge issue, GPS Stops working after like 30 minutes of use. It basically turns off if you have it on too long.
Heres a way to replicate it:
Open Telenav, Enter an address, let it guide you for 30 minutes, and before that, you phone should vibrate (force close vibrate) and the voice over will say "cannot get GPS Signal in this area".
Is anyone else having this issue?
Thanks
I will try that tomorrow on my way to work. What is a good test and signal quality for the GPS? I downloaded GPS Test lite from the market. I am running EF02. I went in my back yard and the test program tells me 7-9 satellites in view, using 2, accuracy 18ft. Does that sound like a healthy GPS signal? Is there a better testing program?
That's a good program, the gps location and tracking works fine,but it stops working after a certain amount of time, and can only be fixed by reboot. I've never had this problem on froyo or eclair, I just hope sprint realizes this issue and fixes it
I actually had this same issue on 2.2 while i would use google nav. I noticed it when i took a several hour road trip about every hour to half hour id have to disconnect my gps and reconnect it.
I have the same issue too. For me GPS stops working in about 10 minutes of use. Google Nav would just sit there with trying to reconnect to GPS and says GPS signal loss. Tried EF02 and EF10 modems.
Used GPS Status & Toolbox app from market to get it working again instead of restarting the phone, but GPS still stops working in about 10 minutes of use.
In the mean time I might just flash back to ACS 1.1.1 or the new one just released 1.2
Yep. Mine does the same.
I'm having a couple of these GPS issues as well, never had them before. I've always been able to get GPS functional on every eclair, froyo, and gingerbread release until now (ef02).
GPS Test app shows around 8-9 satellites in view, and only 1-2 in use. Previously, I would always have 8-9 visible and 8-9 in use. I think this is causing my second problem which is:
GPS accuracy is way down over previous releases. It used to be near-pinpoint accuracy, now it's much less accurate. Today driving in to work, the accuracy was so bad that when I was on the highway and if there were secondary roads close to the highway, maps would often place me on those secondary roads and start telling me how to get back to the highway. I've never had this problem before. I'm also getting the telltale large blue circle in maps depicting the poor accuracy.
I'm also having the problem where GPS signal will just totally drop after 10-15 minutes of navigation.
I've tried the usual tricks with resetting agps, etc., nothing has worked so far.
Edit: I'm on the EF02 modem, not sure that it matters though
Wow that really blows, if this the case, I'm going back to Froyo ... I rarely use the GPS but when I do, it's for long trips and I can't have it dying on me traveling to places I am unfamiliar with. Thanks for the bug report on this OP, it seems everyone is having the problem, regardless of baseband EF02 or EF10.
Glad to find out it is not just me having this issue.

Same problem here. Went back to Froyo EC05, no problems again.
I guess I'll be waiting for them to make progress. GPS is essential for me, I use it on a daily basis.
I had the same problem and eco3 modem works for me
I have been using it mon,tues.wed all day 700am till 800pm and it never disconnects on me.
So far so good
After trying everything on Anonymous to get gps to work I finally gave up. Odin'd ef02 stockplus and gps works flawlessly...used it for an hour drive today without any hickups..give this rom a try....very smooth and fast for Rfs
The Stock Roms works fine!!!

+1 on that my brother! I believe the problem lays in the Ext4 Roms and the other modified roms. The stock roms work perfectly. This is the first time I am endorsing the stock roms. I believe our developers are trying to do a lot without the source code.

Odin the EF02 stock roms. They have a lot of work to do on the Ext4 Roms to get them to work properly.
Just had to vent (at myself, for not having the time to delve into non-stock ROMs the right way but still installing the leaked EF02): my GPS is completely wonky with EF02, and I've tried the EC05, EF02 and EF10 modems. None make a difference.
Now I'm debating whether to go back to EC05 and wait for the official link, or just live with it. Kicking myself...

It happens on EF02 stock as well. I had the same issues on a road trip I took after switching to EF02, would have to reboot constantly in my case to get it working right. Then tried flashing the EE03 modem, still had the problem. But as goku said, flashing to the EC05 Froyo modem seems to have resolved it.
I have had my phone replaced 4 different times and I have the same problem with each one. Whenever I update to a ICS ROM (stock or CM9) my Wifi and Cell signal goes to crap. I lose 10db on my cell signal and my wifi drops a bar or two. Also, my phone seems to randomly lose my data connection and doesn't come back unless I reboot.
This really kills me because I already have bad signal at home at work so it makes my phone useless.
I am probably going back to Gingerbread because of this unless someone can help. Any thoughts?
dear i have also same problem
dear i have same problem plz give me gingerbread link to dowload that version
i am very worry about this plz help me
thanks
kernel
Try changing kernel, like AIR Kernel.
This topic has been discussed a lot of times on internet but I am really concerned about fixing my phone as no matter what, if i am on 2G, 3G or WIFI I stop having notification after 15-20 minutes. In fact I tried PINGING my device and PING stops really after 15 minutes. Anyways, currently I am desperately waiting for 4.3 and there is just no NEWS of the RELEASE DATE whatsoever. But also I am not much into CUSTOM ROM or KERNELS but was wondering if I can only update the KERNEL version (i.e., FRANCO if any one suggest) and solve this issue. I want to be remain on STOCK ANDROID but is it possible to only upgrade the kernel ?
Also I would need tutorial for the quickest root and the safest kernel to follow and keep upgrading it all the time. Thank you.

The choices and threads are out there for you if this is truly bothering you. You can stay stock and flash a couple of files to test out if your issue is fixed. Rooting is not the end of the world and you can always go back. As for tools there are multiple stickied root methods just choose one. Also no guarantee 4.3 fixes the issue. I flashed a couple files from Development in the Wifi/Fix thread and my problems went away. May for you it may be the prima drivers but you wont know until you do it

any APP has the same issue. I use the following and in everything it is the same frustrating issue.
whatsapp
Talk.to
Email (Even if the settings are on 1 hour INBOX CHECK, it never works until i manually do the sync)
These are the only apps I always expect to notify me INSTANTLY. Also it was the same in Google talk and any other IM apps.

Thanks but it also happens in 2G because 3G I can't use due to my work environment where I can't keep charging my phone and in 3G this phone battery drains quickly. Well, two more weeks ill wait for 4.3 and if Google is still fooling then I will go ahead with ROOT and some KERNEL experiments. Thanks a load.
