Download GPS Test by chartcross. In settings clear AGPS data then download fresh AGPS. Then go to the sat locks screen. It should pop up in a couple of minutes.

Kenny im trying your method first since its alot faster. I have gps status and the WIFI im on wont let me connect to google play. Tried installing from laptop and wont go either. GPS status has can clear agps and get new aswell so will I update the thread

It is known that the Epic must connect to a data signal to get GPS. So since you can't get to Play store I am guessing that is the real issue.

I finally found a good wifi connection and was able to get gps to lock. I then went away from the wifi and it stayed connected with no data. However when I turned gps off and tried to lock again with no data it won't lock. Very annoying. Is there any workaround aside from anynomous?

No. I believe the epic either requires a data or cell connection to enable GPS.

Ok let me clarify how to get gps when u have no service. This has been working for me for 2 days. You can not be in airplane mode. You must have airplane mode turned off and have precached map area on google maps prior. I use gps status to lock then open gmaps then ur good. Thanks all

So your status bar actually says "no signal" that circle with the line through it?

GPS

I haven't seen any new updates on this in a while so am I the only one still having problems with the GPS not working?

Mine is acting up as well... Google maps seems to be working, but I tried using the speedtest.net app, and it failed to acquire location... hmmm....

The GPS issue has been "fixed". Most people's A-GPS got updated and they're getting locks again.

I have, speedtest.net isn't working.... but maps seems to lock on.... not quite sure what's going on.... maybe it's the speedtest app??? idk...
edit: just tried speedtest.net on my i..... err.... "other" phone.... and speedtest.net isn't finding a location server either.... so it's not my nexus.... maybe the GPS is working after all...

The "fix" does nothing for me and I've tried GPS test GPS status and faster fix. Have reset the a GPS setting and still nothing. The GPS icon doesn't flash or fill in it just stays empty until after about 30 seconds then tells me unable to get a location

Google fixed A-GPS data that they were serving phones. People are now reporting that they're able to get locks again. Mine's been a bit shaky still, but I do lock eventually.

Try another rom. I was using cm10 alpha and was starting to blame my gnex. But then I tried jelly bean stock, liquid ics, and some other rom. And GPS started to work like a champ. Instant GPS lock. And while I was on edge too! Try another rom.

i cant get NAVIGATION app to lock at all -- on the OTA deodexed JB rom from the forums -- did full data wipe re-install still cant get a lock

Try liquid ics. I'm using he GSM nexus with T-mobile. This would help determine if its a software issue or hardware. Yesterday I put liquid ics and stock jb.to the test by driving around my city and they both locked on and responded very fast.

Last week, some bad A-GPS data got pushed out to Nexus devices, and people were unable to get a GPS lock for several days.

I had no issues when everyone was reporting GPS issues but today my GNex took at least 3-4 minutes to lock onto GPS. I'm not confident it isn't ROM issue, I'd have to run some other tests to isolate it, but there is definitely something weird going on with GNex's GPS.

GPS fix? AOKP maybe cm9 ics

First of all I'm on AOKP 715 m6. My gps was nonexistent even though it was good on earlier versions. I was running a modded vle radio which i don't remember the source. Anyways, i flashed tdj's modded vle radio in one of his threads and gps initial locked on in less than 5 mins. It then locks on in less than a min after that.
At first i thought it was the kernel, so i flashed different ones, but no changes. however the radio definitely fixed it for me on AOKP.
So to those with gps problems try flashing tdj's modded radios. Sorry for being lazy on my phone and not linking them.

This was discussed months ago. Its the basic reason modded radios were made. Apparently the RILS break GPS. So yes GPS won't work unless you flash one of the modded radios, as you found out by accident lol.

I am not using a modded radio I am using the one that came with the ics official update uvle1. And I am running AOKP M6 7-15. My GPS is the best it has ever been I get instant locks even indoors. And It is accurate too. I have also used other roms and had the same results.

yeah i remembered that discussion, and I flashed a modded radio and it worked for most ROMs. I was then really bothered that my uber great locking GPS was no more... I seriously thought I flashed TDJ's radio because I had a file with the same name in my sd card. So I was bummed and decided to test kernels because thats like testing 2 things at once lol. But yeah I ended up checking the md5 of the modded radio i had on my sd card and it turns out it wasn't the same. Must have gotten it from a different thread even though the file name was the same.
But yeah it's just a little reminder to those who have GPS problems, that even though you may think you have a perfectly working radio... you should just flash TDJ's radio mods just in case.

Just flashed TDJ's modded UCLE1 radio...still no luck with GPS

What do you guys mean when you say "breaks GPS"? I am trying to determine if my problem is similar to yours.
My problem is not really an issue with the GPS but an issue with Google Maps. When I use navigation from point A to point B, say Schaumburg to Chicago, it'll always speak directions as if it's going from point B to point A, although all the on-screen directions are correct.
I uninstalled the app and reinstalled, but have not yet tested to see if that fixed it.

Have any of you tried the agps fix for cm and aokp ROM?

I have. I don't know why, but running CM9, my GPS doesn't work no matter what. Maybe the GPS chip broke or something.

Yes this is what I have to do every time I flash a ROM and GPS breaks. I made a thread about it and there are also 2 more threads. Its a zip file you flash through cwm. Also people don't forget that if you're on cyanogenmod that you have to go into location services, GPS source and tick "use internal GPS". Or else GPS will barely work.

didn't know he had a ucle1 radio, he has a uvle1 radio though maybe try that one.
If it is the first time you're trying to lock on, it might take a while, you should turn off wifi and data while leaving your GPS on. Stand outside with it on for 5-10 mins or so, it should get a lock on. After that your GPS locks quicker the more frequent you use it.
I think a lot of people would expect GPS to lock on right away, this only happens if your phone has recent locks to the GPS. I find it best with wifi and data off and to just leave the gps on and google maps on.
btw i've tried the AGPS patch before, but if you have a crappy radio it still won't connect lol.

Here's the screenshot without data or wifi. This is inside my house. Notice the gps signal has a constant dot in the middle, i know for aokp this means i have locked on.probably the same for cm, not sure about tw, haven't been on that for a month.
Anyways it has went as low as 4m, so pretty good. This is without apply the patch.

Download GPS status. Its free in the market. Will tell you how many satellites you're locked onto just for kicks. 4m is very accurate.

4m is amazing! and when i used GPSStatus, it said i had 20+ sats available, but only locked onto 1 maybe 2? WHY!? Grrrr...

Lol just tested it, 7-8/19-20 sats. This is inside my house. I'll check it out when I'm out and about

Download gps test from the market. https://play.google.com/store/search?q=gps+test .. in the app press settings, clear agps, then update agps

Any luck with this? My phone also lost gps function. Im rooted and have been flashing the Jedi roms.

I didnt have any luck....

I guess it's off to the tmobile store after flashing back to stock.

Why not give some useful info at least. .. is it seeing sats but not connecting or nothing at all
Sent from my SGH-T889 using xda app-developers app

Mine is not seeing any satellites. When maps is open my location just jumps around based on cell tower data and eats battery. I'll have to find out how to put it back to stock, and maybe I'll get lucky and it'll work.

Odin'd back to stock. Didn't fix it, but I really didn't expect it to. A new device is coming tomorrow.

They are delivering it Thanksgiving day??

That's what the receipt says anyway.

Gps issues

There are no posts in here about it, so am I the only one with issues? Signal loses lock about every 5 seconds, and bounces me all over the place in Google maps, and Navigon. I'm completely stock. I downloaded a gps app, and it's locking on to 12 or so satellites.

the google maps - it has navigation built in

try to clear data and cache settings

just a "duh" note, make sure GPS is on and not just network location, I'm sure you all have but it never hurts to triple check also check your powersave mode, not sure if they may have an effect on it.

My gps is terrible too. Not sure why... Looking for a solution.

Faster fix and top ntp do the same thing it changes the GPS server from a generic one to one to what part of the world you live in
Then use GPS status/GPS test to update agps. Bam good to go. As long as it's not a hardware problem

Same here. I also tried bending the "leaf contacts" on the phone so the antenna makes a good connection.
My phone can see 25 satellites but it can't get a GPS lock, any ideas?

I have had serious problems with GPS on custom ROM's (among other issues). They would show the satellites, but it worked like garbage.
I did a full wipe, and ODIN'd to stock, and it's been great ever since then.
Have you tried making a nandroid, and doing a factory reset and full wipe, to see if it works well after? That should allow you to rule out if it's hardware related or software.
