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!

***oops wrong topic***

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
one.click.clockworkmod2.5.1.0-flasher-fixed.zip
ROM Manager (after updating to clockworkmodkernel.zip)
failed rom via Rom Manager/ClockworkMod 1506bdf2e04b.update-SPH-D700_DI18ToDK28.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...

Great Tip. Got my Gps working now

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

Gps?

Hi, I have a rooted eco5 with absoluetly no bloatware. Whenever I use gps it says it cannot find me. Is there anyway to fix that? I've heard of an app that fixes gps, but I don't remember the name. Also I'm sorry for not using the search function, lol

GPS Status?
There is also a mod in the development section that suppose to help fix it.

Thanks for the help. It was gps status.

Yes. Unfortunately the Epic suffers from a few GPS problems under EC05 and we're working on a comprehensive fix for them. However, we're still trying to understand exactly what folks's problems with the GPS are. If you're willing, you could be an incredible help with that.
Has your GPS ever worked prior to EC05? Did it stop working after you upgraded, and hasn't since?
Also, please use GPS Test when testing the GPS as it allows for the easiest understanding of what your current problems are. When using GPS Test, you'll probably want to go into Menu, Settings, and disable the "Keep screen on" option so your screen doesn't shutoff while attempting a fix.
Can you run GPS Test and report what happens? A "good" fix is when the "GPS on" light turns green in 10 seconds or so. A "poor" is when it takes anywhere from 30 seconds to a few minutes to get a fix outdoor in clear skies. "No" fix is when it's unable to get a fix even after 4-5 minutes of good visibility.
If you can report back how GPS Test works, we can debug this a bit further.

I can report on a rooted stock EC05 that GPS has stopped working altogether. Using gps test it never gets a signal. In Maps, the gps icon doesn't even turn on any more. Yes, gps is enabled under settings. This behavior first appeared after I installed Advanced Task Killer and I am not sure if ATK is killing some process that keeps gps from starting. Any ideas or any more info I could provide you to try to help figure it out?

So in GPS Test the "GPS on" light just stays yellow and the GPS icon in the notification bar just blinks? And this is across full reboots (power cycles) too?

It's probably unrelated to ATK. Did it work in EC05 prior to ATK?
We've identified a few issues with the GPS in EC05, one of which is that the GPS can crash and programs are no longer able to use it, but it recovers again after a full power cycle.
What we haven't been able to identify yet are the exact causes of why the GPS doesn't work at all for some folks. Mostly since everyone who has posted in the development thread now have working GPSes, so we no longer can get solid debugging info on them.

Yes, definitely. Are you familiar with running adb commands?
If you can, what would be really helpful would be to enable "USB debugging" on your phone, and reboot (full power cycle) it. Then, as soon as the phone is booted (network is up and it's done "Preparing external SD card"), plug in the USB cable and run on your computer in a command line:
Code:
adb shell "logcat -v time > /sdcard/logcat.txt"
That command shouldn't return immediately, which is what we want. Wait a few seconds, then run GPS Test and wait about 30 seconds or so. Then close GPS Test, and do a Control-C in the "adb shell" terminal which stops the logcat.
Finally, pull "logcat.txt" off your SD card and either attach it here, host it, or email it to me, I'll PM you the details.
Sorry it's a bit complicated, but that's the only way we've been able to get all the necessary information on what the GPS does from boot through a first fix attempt. If you have any questions about running that, feel free to ask.
Thanks!

Hi Mkasick,
so I just rebooted, and fortunately (or unfortunately) gps works. This is how it seems to go for me. It will work for a while on a fresh reboot, but after a while (maybe a day or half day) it fails to start again. When it doesn't work, the gps test behavior you describe is exactly right - icon says "on" and icon light stays yellow. So I assume the ADB logcat file is not meaningful to you if it works right now, correct?
I should also say that from time to time, toggling other radios using the drop down menu from the status bar also fails to work. Wifi specifically will fail to toggle on. Again, this usually happens after the phone is on for a day or so. Glad to hear that ATK is not the likely culprit because installing it has really improved my battery life a lot.
Let me know what I can do to help. You are awesome for working to make this phone better for the rest of us who don't have any coding skills. Should I get that logcat file the next time I notice the gps won't start?

OK, there's a few different issues that can cause that.
One is that the GPS will randomly crash upon exiting or switching away from a GPS-utilizing app, roughly every 1 in 20 times. When it does, the GPS no longer responds to any commands and the GPS icon will stay lit even after you close an app. We're finishing a workaround for this and I'll post it in the next day or two.
The other issue is that the GPS's ephemeris data appears to go stale earlier than it should. Here the GPS appears to work normally, with regard to icons blinking and such, it just can't use any satellites it finds for a few minutes, but if you're outside on a clear day it will eventually fix again. The existing workaround may address this. If you find the GPS won't fix, you can toggle the GPS icon outside of an app and that will download new assistance data which should hopefully help.

Probably not. Actually it might be hard to debug the GPS issues further until I get the crash workaround posted. In the meantime, you can at least discern if the problem is the crash by installing CatLog, and after the GPS demonstrates issues, open the CatLog and look for a line that says:
Code:
E/libgps (####): RIL Request: ERROR 1 (n=110, r=0)
The "n=110" is in particular a good indication of a GPS crash.

I've seen this on occasion too, but not frequently. I haven't had a chance to look into this issue further. It's possible ATK could be responsible here.
Mind running a few days with ATK off just to see if those issues continue to persist?

Thanks! At this point, I'm not sure a logcat will show anything new as long as your GPS does work after reboot. Probably the most useful thing would be to report if the existing workaround helps when your GPS stops working, as long as it's not due to a crash (which CatLog can verify).
I'll try to get that second workaround posted soon. This GPS crashing is annoying and hinders the debugging of other GPS issues.

So neither of the types of crash you describe really apply to what is happening to me. After my gps fails, the icon never comes on. Under the settings menu it says it is enabled, but no application ever gets the icon to come up and there is never any kind of message saying gps signal is lost or unavailable or anything like that. I will try to do what you say with regards to CatLog and send you whatever files seem relevant. ATK will be turned off.
Thanks again!

That could be a crash. If the icon is on when it crashes, it will likely stay on until "Use GPS satellites" is toggled, at which point it will turn off and stay off. If the icon is off when it crashes, then it never comes on again.
The status of the icon doesn't matter as much as the GPS is utterly unresponsive as far as the phone is concerned.

I've just posted the crash workaround. Feel free to flash it (gps_request_sync-EC05.zip in that thread). It's been tested on stock EC05 and SRF 1.1.0, althugh I think it should work on any EC05 ROM.
That alone may resolve your issues, if not, also try the assistance workaround in the same thread and we can go from there.

My GPS was working perfectly for months using the forced cold start. It has had the problem since the update to Froyo.
I tried this one and it is a "fail" as doesn't work at all after a couple of days.
http://forum.xda-developers.com/showthread.php?t=1028618
It seems to work at first but I think the "fix" has to do with rebooting the phone, as after a couple of days of uptime the problem of the Epic not using satellites that it sees returns.
I am now trying this one:

My GPS randomly gets no lock without a reboot. This has happened after EC05 update. Now have Bonsai 4.0.1 and Genocide 1.0 kernel. This fix should resolve that right?

GPS issues..

The GPS on my phone has not been locking since I flashed CM7. I searched through some fixes but none seemed to help. I went back to the backup I had before I put CM7 on and the gps seemed to lock just fine. So I tried to flash while it had a lock but still nothing. I even tried using the GPS status app and that did nothing. Any other fixes that could help? Thanks

Have you tried flashing a different kernel? Maybe x99's or scaryghoul's as they are aosp roms their in the dev section. Always wipe your dalvik-cache b4 you flash a new kernel,I have very few issues when I do.

My GPS actually locks instantly after I flashed CM7 and x99
I have only one problem. Sometimes it'll lose a signal and will never get signal again on its own.
The quickest and only solution (that I know) is to quickly exit Navigation, then go in and tap on the most recent trip and voila, instant GPS lock again.
Not a huge problem, but a weird annoyance.

I assume you mean Google Navigation? If so I think that is a problem with Google Navigation itself. I have the exact same issue on my stock but rooted Shift. It will lose GPS lock, usually within the first couple of minutes. It then is never able to reestablish the lock on its own. If I exit Navigation and go back in, or turn the GPS off then back on it gets a lock and keeps it.
I just started trying Google Navigation. I have been using Telenav since getting the Shift about 2 months ago. With Telenav I never lost GPS lock.

i've found, atleast for me, that this tends to happen when i have GPS off, then turn it on to use it and open telenav and it just cannot find a GPS lock. so i leave GPS on and reboot my phone, open televav back up and it finds a GPS lock pretty quickly. it's like if i turn off GPS, i can't get it to work again until i reboot my phone...
needless to say, GPS sucks ass on this phone. i've never had a phone with GPS problems like this one. but other than that, everything is perfect.

mine happens when somebody attempts to call me, the lock disappears. after i ignore the call, like others have stated it locks on instantly when i go back into navigation. but i do prefer telenav over google... traffic is on point :]

i've been having gps issues, i think its a bug in google maps. havent had time to test root on it yet

It seems like nothing wants to work. I installed the x99 kernel and my GPS will still not connect. It seems like it will only connect when I'm on stock. For some reason I cannot get it to work with CM7.

Look up the ##gpsclrx# fix. I don't remember all the steps but it requires you to reflash a Sense rom, dial ##gpsclrx#, enter your MSL (found via MSL Reader on HTC devices), reboot, maybe clear cache, and then reflash your rom of choice. Fixed my CM7 gps issues (even with the MSL "password" prompt telling me that the password was wrong).

Nan to stock . Use GPS on stock leave it on. Nan to or redownload cyanogen and GPS will work. Happens to me when first putting in a rom sometimes.

I have this exact same problem with Google Navigation. It "loses the lock" after a few minutes like clockwork, but I can get a perfect one again right after, making me believe that it is the application and not the GPS. Is there any fix to this?? It really is annoying.

[Q] Wonky GPS on AT&T S4?

Hi all. I'm having a bit of GPS weirdness. GPS can get a lock quickly and accurately, however, I have to turn it off/on every time I open an app that uses it. Otherwise, it won't ever find the location. Once I turn it off/on it picks up and stays locked while the app is running. Also, if I switch to another app that uses GPS I have to do the same thing to get a location fix.
So obviously, the GPS function works, but something in the OS is not recognizing it until it's reset. Not the end of the world, but definitely annoying. Is anyone else seeing this?
This is on the AT&T version, by the way.
Thanks!

Check if you have GPS and Mobile Networks turned on for Location.
Else return it.... and get a new one... GPS has been quick and spot on...

GPS is quick and spot on. Per what I wrote, I have to turn it off and on for an app to be able to use it.

I've noticed this once, where something in the background was starting a GPS lock, but seemed to cancel, and retry before it ever succeeded. Turning the GPS and location services off, then back on worked for me. Haven't had an issue since.
If you haven't tried resetting to factory default, I suggest doing so.

Well, I was hoping for a bit more granular approach than a full reset. I'll wait until the new OTA is applied before doing anything drastic.

Less drastic than returning it. I suppose it depends on how attached you are to your current setup - but I would say if you're experiencing that issue repeatedly, the factory reset is exactly what you'd need. I doubt the OTA will address it since it appears to be an isolated problem.

So, yeah. Today's OTA update did indeed fix this. i would press my own Thanks button, but that would be sinning!

Hi all. I'm having a bit of GPS weirdness. GPS can get a lock quickly and accurately, however, I have to turn it off/on every time I open an app that uses it. Otherwise, it won't ever find the location. Once I turn it off/on it picks up and stays locked while the app is running. Also, if I switch to another app that uses GPS I have to do the same thing to get a location fix.
So obviously, the GPS function works, but something in the OS is not recognizing it until it's reset. Not the end of the world, but definitely annoying. Is anyone else seeing this?
This is on the AT&T version, by the way.
Thanks!

Same issue here and it's driving me INSANE. lol I am on stock rom just rooted and unlocked. If i ever want to use Gps I need to turn on/off the toggle. Very annoying. Wasn't like this from day one so something must have changed. I have tried clearing the cache for Google Maps as well as re enabling all of my location settings downloading aGPS data data did not work

Do you have yahoo weather installed ?

I do not have yahoo weather installed. Another bit of info I forgot in last post:
I do sometimes, in a quick glance, see the gps icon running out of the blue. The notification of "acquiring gps signal bla bla" is present as well.. only to disappear within seconds. So it seems as if a specific service or application is using the gps in a faulty manner, blocking other services/applications from using it. May be why resetting the gps allows the application your trying to use access it. (my only fix)
If someone could read a logcat of what's going on I could post one up

I've actually been combing through the logcat output and see a line reappearing often referring to "no secgps file" I do remember on my previous devices messing around with that file and others for GPS configurations. Does anyone know if this file is supposed to be included in the stock rom?

BUMP
Seeing a few other posts in this sub forum for GPS locking issues, and most the others see the fix to turn on and off via the toggle.

It was Yahoo Weather for me! As soon as I deleted it the GPS started to work well with apps that need it such as Waze and Google Navigation. Wow. Thank you. I was going crazy. Tmobile GS4 btw!

GPS Randomly Turns Itself On...

Having a weird issue with the GPS on my AT&T LG G2. Phone is unrooted on stock firmware. The GPS icon will randomly appear in the nav bar. Sometimes when I check after that, it will be turned on and I can toggle GPS off. Other times it isn't on by the time I check it. I always leave GPS off for the battery life savings. I've tried doing a factory reset and immediately disabling Google Maps. This seems to keep it from happening, but once I re-enable Maps, it will again start randomly turning on GPS. Even after disabling Maps at this point, it still does it. Only a factory reset then immediately disabling Maps seems to keep my GPS off. Any ideas?
Thanks!

I've noticed this as well. I keep mine on but it location icon started flashing earlier in a phone call.
No clue why that would be.

Had the same issue, it's something called carrier IQ that tracks you without consent. Fortunately you can remove it with root access. There are a couple of threads in the qa and general sections which address this and solving it. Search for them and youll be on your way.
LG G2

In on Verizon. It wasn't reported to have that and I did run a check, which was clean, just to make sure.
Here's my light flashing after turning the screen in th change the channel.

Not abnormal at all. This happens when your device needs to refresh locations for multiple apps to work efficiently. We are not alone. Android thing.

What have you guys done, that BIG BROTHER is keeping tabs on ya lol

Try disable location reporting in Settings. Also, there's a good chance Google Now! is using to access your whereabouts, unless your really want those cards, turn Google Now! off (voice search still works even after that). Look around Maps settings too, and if you see location sharing or let Google use Maps data or something like that, turned that off too.

This is how I fixed it, too. If you can't figure out how to remove CarrierIQ then you can just disable it after each reboot by going to settings->apps->running->android system->stop.

Hi,
I'm having the opposite problem. When I enable my GPS, after about a minute, it turns off. It used to work fine.
I have a Samsung, but I simply can't find my issue anywhere and I ran across this thread and I'm just praying someone might have some idea what's going on. It's frustrating!
Thanks
