Please Fix My GPS - Verizon Samsung Galaxy S III

I have a rooted s3 and I love it. Except I NEED MY GPS! I just started a new job and need my GPS to work. I have tried multiple ROM's and can't get any of them to work with it. Sometimes if I switch to the GPS Test app while I am using the navigation it will pick it up and then automatically lose the signal when I go back to the navigation app. I have tried the Maps trick deleting the cache, I have tried using GPS Status and Toolbox and all that does is drain my battery. Is there no other way except returning to stock? Please help.

I just used it about an hour ago on cleanROM. I haven't had any gps issues yet.
Maybe read this thread.

Trying the flash now.
I have tried CleanROM, JellyBeans, Eclipse, and a few others and my GPS wont work on any of them.

You should try going to settings, accounts, Google, then location and services then allow Google to use your location. This is different then just turning on GPS.

I have done that as well, still can't get it to work.
I just flashed Synergy, and then flashed the GPS tweak, still nothing. This is so frustrating.

There must be a solution.

Simple mechanical GPS fix involving tightening the back frame of the phone
Hi,
I have a simple GPS fix that worked for me. I'd like to mention that the solution may not work for all but it did work for me after I tried just about every fix possible. For example I flashed back to stock, performed numerous battery pulls, used many of the AGPS patches, made numerous edits to the gps.conf file, reprovisioned my phone, checked different ROMs, uninstalled/reinstalled Google Maps, cleared data for Google Maps and Google Service Framework, and so on.
I tried all of the above methods because my GPS would take forever to get a fix both indoors and outdoors (I know it usually takes longer to get a fix indoors), wouldn't hold the fix while navigating and my GPS apps kept stating "Searching for GPS", would see 20+ satellites but would never lock on to them...man it was really frustrating. I just about gave up.
However, as I was trying to follow another procedure to fix my GPS which required me to pull my battery I noticed that when I removed my back cover that the back frame that has all the screws was slightly loose on the left side. Once I tightened them all up my GPS worked immediately! I've tested for a day and I consistently got a lock on the satellites in about 2-15 seconds depending on my location. My navigation also worked and wouldn't cut in and out.
Like I said it may not work for everyone but I would recommend that if you have a GS3 definitely check the back frame of your phone and make sure everything is secure. I've tried my GPS on the stock and CM 10 stable ROMs and I have achieved GPS locks consistently.
I hope this helps. Maybe this has already been shared but I figured I would post in case some of you haven't seen it yet.
Cheers.

Bad GPS lock with WIFI off.

My GPS stopped doing accurate readings when i flash roms with the ziggy gps fix. the only way that it gets accurate(within 20m) is with wifi on and connected, if its off it says accurate within 3700m. Thats not too accurate if i might say, anyone else having this problem/ found a fix for it?
Check the following thread:
http://forum.xda-developers.com/showthread.php?t=1025631
I've done that, and it knocks my gps off completely. Any clue why its attached to Google location services?
Sent from my ADR6400L using XDA App
Interesting, I attempted the same thing and I am unable to get a lock when I disable the Google Location Services.
I'm running on Das BAMF 1.3.2 with the kernel update 3a which includes gps fix/enhancement from Ziggy.
I've been testing how quick I get locks when using the Navigation and I am still seeing a considerable amount of time before it finds a GPS signal. I've also used GPS Status from the Market to reset and download GPS data but I haven't really seen a difference.

Used this method and Ziggy's GPS mod and I get a lock within seconds as opposed to 10 minutes. If I turn on Google Services it goes back to a 10 minute lock time so I think it has more to do w/ the Google Services rather than modifying the GPS Config through Root Explorer.
Edit: I will add that initially my phone will say "GPS Location is Currently Unavailable" and 2 seconds later it gets the GPS lock /shrug
Well mine stays searching when the Google location is off, never gets a signal. What is the stock gps server so I can switch it back?

Well I just found that as long as WiFi is toggled on, the gps will lock on no matter if there's a connection or not. Tied into he WiFi somehow?

That is odd that WiFi affects the GPS locking. I'm trying to find anything I can on this. "Searching for GPS..." in Navigation is annoying as heck.
I also had a sneaking suspicion that toggling wifi on and off caused gps lock issues, I was using another rom at the time, but for some reason, all of those problems ceased when I flashed TeslaCoil and completed the gps conf fix.
Not withstanding, gps should lock quickly using only stand alone, and right now, my gps works splendidly

You can grab it here:
Improve GPS lock - credit Ziggy471
It edits the gps.conf so the NTP_SERVER=us.pool.ntp.org
That comes default on the roms I use tho. Still attached to WiFi switch. What's the closest lock you can get with your gps?

i was having GPS issues with the last two bamf kernels. google maps seemed to lock onto my location after a few seconds or a minute, but other apps that tried to use the GPS would never lock on. i noticed when you go into google mapls, the GPS icon/animation appears on the status bar.
the GPS icon would never appear for other apps that tried to use GPS when using the bamf kernels.
with the stock TB kernel, all is well.
Ok, gps is definitely tied in to WiFi. Without WiFi on its 3400m away and with it on is within 20-50m. That only happened with the ziggy fix so maybe if anyone could show me the original settings for the stock gps server file I could change back and forth and test what the problem is.
Sent from my ADR6400L using XDA App
So I rewrote the gps.conf back to the original north-america setting and that fixed the problem. Any clue why ziggys rewrite of a word in that setting would mess it up so much? And how is it ppl are supposedly getting improvements with that, like what exactly?
Sent from my ADR6400L using XDA App
I don't know what the rhyme or reason would be for this gps issue, because it's so random, there is no pattern to this mess:
1. Got the phone, gps worked great.
2. Rooted phone, still worked great.
3. Flashed first rom, Virus to be exact, still worked great.
4. Several days later, with no rhyme or reason, I noticed that Cardio Trainer had not picked up location
5. Factory reset, problem still persisted, could not lock on to any birds, confirmed with gps test app.
6. Flashed CWR of stock rom post root, still not working.
7. Flashed RUU stock from fastboot, working again perfectly.
8. Have flashed 2 non stock roms since, BAMF 1.3.1 and first TeslaCoil (current) and gps still working perfectly
I can't think of what could have possibly caused this, but now that gps has been stable for about one week and I haven't been using wifi, over the weekend I'm going to toggle between wifi and 3g and see if it causes any issues.

I'll be trying the new Das BAMF 1.4 to see how it behaves. Wish me luck!

Joanni, I'm having the exact same issue that you've been having. With Google services on, I get the wide area. If I turn it off, I get nothing. The only way I get a lock is with WiFi on. I'm currently running Virus ROM.
I know enough to be dangerous when it comes to digging into my phone. I generally just follow well polished instructions. How would one go about trying your fix?

Joanni just edited the gps.conf file to read NTP_SERVER=north-america.pool.ntp.org
That was the original setting. It has been said that changing the setting to us.pool.ntp.org has fixed peoples GPS locking issues but in my testing I found no benefit either way. What I have found, is that turning WiFi on will enable the GPS to have better accuracy in finding your location (20 meters to 50 meters in my case). This is exactly what the popup says, the first time you launch Google Maps.
If you wanted to check what your gps.conf file has set as the server, you can use Root Explorer and browse to /etc/gps.conf
There is also an app in the Market called FasterFix that will change the server to north-america.pool.ntp.org for you.

GPS Lock Troubles

I'm sorry if this is addressed somewhere, but I couldn't find anything solid while searching. I use my G2x every day with SportyPal Pro for my bike rides. I am currently running stock 2.2.2 with root and am having some difficulty attaining an initial GPS lock. It seems like when I go to launch any GPS app, it will not get a lock. To get it to work, I have to open GPS Test, select tools, and clear out the A-GPS data. After doing this, it looks almost instantly and will keep a lock forever.
The next day, however, I must do the same thing, and this happens nearly 100% of the time. The funny thing to me is when I open GPS Test, it will show a strong signal from a lot of satellites, around 7-9, but it doesn't use these signals to find the lock. Again, after resetting the A-GPS data, it works every time almost instantly.
I have just dealt with this but it is getting more frustrating. Today, GPS Test wouldn't load, just kept showing a blank screen and force closing eventually, even after fix permissions, clear data, uninstall and reinstall. Only after another reboot, would GPS Test even load. I can't explain because I don't know well how the inner software works, but the GPS seems to have a hard time relocating itself when using the cached A-GPS data. Any fixes that anyone knows of, or things I could try?
Thanks a lot in advance.

When you launch the app and go to the satellite view screen, press menu, and it is one of the options.

Sadly, I am having the same problem
I think I'm having the same problem too: I can pick up plenty of satellites (more than the 3-4 required for a lock), and they turn green, but I don't actually get positioning data available.

Well, I guess if you are seeing the same problem, it could be a software failure. Why can't Android phone makers release a phone with GPS that works out of box? Do they not test these things? Hopefully the Gingerbread update addresses this issue.
I have GPS issues often as well.
Sent from my LG-P999 using XDA Premium App
I don't have this problem but I have heard of others that do. My device locks in literally 3 seconds and is accurate to 5 feet. I have to say it's the best GPS I have ever used.
I think this problem is an android issue not hardware. I have to load gps test on my vibrant before being able to get a lock also. Wont lie the lock time on this phone is considerably longer but when finally does lock its strong and accurate.
via LG G2x
It takes me forever to get a GPS lock too. However, once it finally gets one, it's fairly strong and accurate.
Gps is way crap now.my vibrant beats the crap out of it... I'm getting like 40000 feet accuracy. It eventually works itself out but still crap..
In gps status in tools deleting the a gps stuff it takes a long time (5 seconds) vs my vibrants agps data. Vibrants clears instantly almost like the lg remembers too much causing conflict....
I cant find my location via gps in google maps. In the gps status app, it appeard to be locking as fix/sats shows 3/3. Ive cleared agps data and also tried to download agps data. Does anyone experience a similar issue? Any suggestions as what elsd i can try?
I dont think its the hardware because it did work the last time i tried about 2 weeks ago. Since then I tried to use a location spoofing app (that has since been uninstalled and mock locations disabled).
On the O2X the mongs at LG left out the gps.conf file, adding it manually sped up lock time no end. I guess it's possible they did the same on the G2X?
I actually exchanged a G2x yesterday that was having problems with GPS
Regardless of whether it was on stock or not, rooted or otherwise, my phone would not find any more than 4 satellites, and would never lock. Factory resets did nothing. My fiancee's phone, however, would find 8 or more within 10 seconds when both phones were set right next to each other. Both phones had a 4/05 manufacture date.
Because of that, I was pretty sure my issue was hardware, as I was never able to get the GPS to work properly. The phone they gave me yesterday (4/12 manufacture date) does seem to work ok, though the screen bleeding a bit worse (but that doesn't bother me *that* much)

GPS doesn't lock..

Good evening guys-
After updating from ICS to JellyBean, my gps cannot find or lock onto any satellites.
If I enable wifi, its accurate to 20meters.. If not, it won't lock even after 15 minutes.
Any help is greatly appreciated-
mine has been similar in PA2.00 and CM10.
It actually will lock after a long time. Sometimes up to 30 minutes.
Interested in any answers... I noticed in the gps.conf file agps appears to be off. I don't know if that is the issue.
Unfortunately searching for a fix just reveals too much information with a lot of supposed fixes, but no consensus so far as i can tell.

Actually agps was turned off to improve lock times...some people noticed no difference with it off, others noticed huge improvements with half the lock time
You can change it to true, then wipe cache and dalvic cache in recovery and see if it makes a difference

is that a 'go ahead and try it, it wont work, but go ahead and try it anyway' ?
It seems like a lot of people are having problems with GPS in jellybean, and some aren't. There's so many 'this worked for me' solutions, but I'm starting to think it's coincidence.
Someone mentioned installing and running copilot once. Did that. it didn't work. Without root permissions what could it really change to improve anything?
I ran Faster Fix. It edited my gps.conf file (which it doesn't tell you that it does) It didn't help. it might have made it slightly worse.
I found a few other gps.conf files for jellybean ROMs, but haven't tried those yet.
This is how we learn and share our info, by trying. Just make a back up of anything that you want to change or replace.
GPS works perfect on my PA Jelly Beaned Infuse. First I ran GPS Test, it took a good twenty minutes if not more for it's first lock.
But now, I get a lock in a few seconds.
GPS Test, is free in the market.
Planning my escape!
GPS Test has kicked my GPS in the butt and got it working with almost every ROM I've flashed. Once you get over that first delay (downloading satellite data?) the first time you run it, it locks on fairly well afterward. At least, that's been my experience

I've already done that. It helped the next time I ran maps. When i left work yesterday I had maps give me turn by turn directions home. It took a couple minutes to lock, but after that it was working.
Then this morning I tried again. It wouldn't lock at all on the way in to work this morning. (only a 15 minute drive)
I also tried editing my GPS conf file this morning. I tried using ES file explorer, root explorer, and flashing. All three resulted in an empty file. ES says it was successful. Root explorer gives an error message 'there was not enough free disk space to complete the paste operation'
Flashing says it was successful, but again, it ends with an empty file. 0 bytes.
The file i used for the flash attempt is here. http://forum.xda-developers.com/showthread.php?t=1817558
With the gps.conf file I'm going to go leave the phone out in my car with gps on and see if it locks.
I understand that developers do a lot of work on this. I'm not trying to be a jerk. I just see a lot of people having the same issue and no agreement on a solution or even what the actual problem is.

I believe this is because there is no solution. If you want to try to help solve the problem, "adb shell" in and start tinkering.
You'll quickly find that GPS is anything but an easy thing to fix. A good SUPL provider for you may be completely different for others.
I can't find the Answer that fixed it for me,
but what I did:
Plug phone in, disable wifi, leave phone near window, and let
https://play.google.com/store/apps/...251bGwsMSwyLDYsImNvbS5hbmRyb2lkLmdwc3Rlc3QiXQ..
that app run... :45 minutes later it locked (GPS icon on Status Bar stopped blinking and showed locked, solid) with 7 satellites.
waited, rebooted the phone, and it locked in about 3 minutes.
-hope this helps.
other than that, love this ROM!

Now that is an actual answer.
I suppose part of the problem for us noobs sorting through 300 page threads is all the filler with people saying "great rom omgz so awesome" even when they are posting on the first page and the ROM hasn't even been up long enough to do much more than flash it and swipe through the home screen.
All through out the CM10 and PA threads there are people saying GPS is working flawlessly... and then other people saying they have some fix. I guess people aren't supposed to post frivolous stuff in the dev threads, but they do.
Anyway, I ended up going back to GB as GPS is something I really need.
Hey guy's, i've also been having allot of issues with GPS just not being what it used to be, and it's pretty obvioius that this is an issue across the board for all JellyBean roms. I think those who mention that "GPS works flawlessly" don't quite understand the issue with AGPS (Assisted GPS), or they are not quite testing it thoroughly enough to see the problem.
To get an understanding of what AGPS is, and how it helps improve initial lock times, have a read here: http://en.wikipedia.org/wiki/Assisted_GPS
Also, to gain a better understanding of what I mean by "cold start" as you read below, and how it differs from a warm or hot start please read the following: http://m.gsmarena.com/glossary.php3?term=gps
That being said, i have been doing allot of digging in the hopes that someone out there has a solution to the problem with AGPS on the CM10 based ROMs on our phone.
To clarify the problem: AGPS does not seem to work and Initial lock times from a cold start can take several minutes, (this is not normal if AGPS is doing it's job). To clarify further, no one is saying that GPS does not work, it does in fact work, it just takes it's sweet time to lock and it seems to rely on pure GPS to download ephemeris data from the actual GPS birds for satelite lock acquisition, rather then downloading AGPS data over the network to speed things up. After the initial lock though, GPS functions as it should. After this point, if you do not use the phone again for several day's, it seems that upon first firing it up again you will experience the long delay in first lock. This is especially true if you keep GPS services turned off ussually to conserve battery. Those who report GPS is fine are probably keeping GPS services on all the time, and your GPS is probably working in the background at times and obviously will start up allot faster then it would from a cold start. (This is where i believe all the conflicting info comes from!)
The only info i have been able to find that did actually have an impact on my lock times was the thread below.
http://forum.xda-developers.com/showthread.php?t=1881655
I just started testing this out yesterday and i have seen some positive results. But i would caution those of you out there, and say that this is probably not a "fix" per se, but it did help cut down lock times in my case and at the very least it is a very inoformative thread that everyone should read.
What i have realisticly been able to achieve from a cold start is about 75 seconds to lock at the fastest. i.e. GPS services were off, i turned them all on, and now i started up GPS Status or GPS Test to get a lock. After that, as long as I haven't rebooted my phone it takes only a few seconds to lock.
How i tested, i started GPS Status, I then went to Tools --> MANAGE A-GPS STATE -> RESET (This is important to ensure you are clearing previously cached data. We want to make sure your previous cached info does not skew the effects of your changes.
I then replaced the gps.conf with the one contained in that thread, and i also made the change that was suggested in the Notes section that suggested modifying or adding a line in your build.prop file to "ro.ril.def.agps.mode = 1". This change set's your gps to use AGPS in Mobile Station Based (MSB) mode. For reference, setting it to "2" would set your AGPS to function to Mobile Station Assisted (MSA) mode. (Mode 1 - gave me more accurate initial locks at the expense of a bit longer lock times, Mode 2 gave me slightly quicker initial lock times, but was rather flaky and my position drifted quite a bit until GPS was running for quite some time.)
If your curious what is the difference between the two modes, see here: http://en.wikipedia.org/wiki/Assisted_GPS#Modes_of_operation
After making the changes to gps.conf and build.prop i rebooted my phone. When phone reboots, i then go back into GPS Status app, select settings, Tools --> MANAGE A-GPS STATE -> RESET, and then back to settings, Tools --> MANAGE A-GPS STATE -> DOWNLOAD (This should force the phone to attempt an AGPS download, if it hasn't already done so upon launching the app).
I have seen this same gps.conf being used in the newer RemICS-JB build. However based on the lack of feedback in that thread, i don't know if this is the golden fix we have all been looking for.
Even though this may not fix all your issues, i hope at the very least it helps clear up what the actual problem is, and how AGPS is supposed to work.
** Important Notes: **
- The version of the config that i was using was the Download the Google Specific No-SSL v3.1
- If you use the SSL version, then it will also require that you download the certifcate file. It's best to just stick with NO SSL as is explained in the thread.
- You should also note that i have cleaned out all the live wall papers, face unlock, and allot of other crap that i don't use to free up space in the /SYSTEM partition. I now have aproximately 21MB free in this partition. I think at least part of the problem with certain ROM's is that they have the /SYSTEM partition filled to the max with virtually no free space at all. I'm no expert on the subject, but i'm guessing that the AGPS data get's downloaded to this partition some where. Obviously if there is no space, then that would cause issues. Several others have reported shortened initial lock times after making room in the /SYSTEM partition.
- Another mistake people are making when testing AGPS and reporting false info, is having their WIFI on when testing GPS. To isolate the issue guy's you need have wifi off and you need to use a tool like GPS Status or GPS Test that shows that actual lock to satelites. You cannot properly test this and see the issue by using WIFI and turning on Google maps. Google maps will look at your reported wifi position and to you it looks like bamm.. i just got a lock in 2 seconds to withing 50 meters, wow these guy's are nut's, my GPS is awesome. Guess what.. your wifi and google maps is awesome.. not your GPS.. lol
- If anyone is familiar with running log's, it would be great if you could do a comparison of before and after. Showing the log of a completely fresh JB build, that shows that the AGPS data is not being downloaded, and then another log after all the changes above (including freeing up space in /SYSTEM) and hopefully it will show that AGPS data is now being downloaded and utilized. I myself am not familiar with logging data on the infuse, so i cannot and will not call this a fix until someone can actually show with real log's that AGPS data is now being utilized after these mods.
Thankfully, I'm one of the lucky ones who have always had a working GPS. It worked great when I was running AT&T stock Froyo, really good while I was on XDA GB roms, and fair > good after I went to PA JB. By far Scott's latest release of PA JB has been the best in this respect, but I can't help but tinker now that I've turned into a Droid zombie Strictly speaking the stock GPS configuration included on Scott's PA JB ROM worked charmingly, but I still had an issue whenever the phone went into deep sleep (say overnight without using it) the GPS lock the next morning took almost as much time coming from a sleep state as a cold boot. So, Like DaMeatMan I decided to give http://forum.xda-developers.com/showthread.php?t=1881655 a go. I chose the flashable option, and like DMM also edited the prop file. I picked the Google "no SSL" version 3.1 instead of the AT&T specific version. I figured I would give that one a try.
I'll keep everyone posted, buy my first impression (could be placebo effect) is that this configuration file and modification actually does improve over the original PA JB configuration by a small margin. Reported accuracy is better (by 10ft on average). Satellites in view and actually locking are 1-2 better than before. My main hope is that I can actually fire up Navigation in the morning and get working directions without having to fire up GPS Test first and relock all the NA satellites. I travel a lot, both for business and outdoor sports (hunting and fishing), and I have come to rely pretty heavily on GPS. I got spoiled when I got my first GPS capable phone because that meant I could leave my handheld GPS at home most of the time and that was one less thing I had to carry.

I have been have many of the same problems as others in this thread but I tried the fix in the S3 thread quoted above and it seems to have helped for right now. The first time I ran GPS Test after rebooting it did take a while (5-8min), but after that I get a lock in few seconds. I used the Google "no SSL" package also. I will do some more testing tomorrow and see if its reliable.

[Q] GPS issues

I read a while back that there was something that can help your phone lock on to GPS faster. Recently I have been having issues locking on to GPS without restarting my phone. When I restart it, it picks up GPS right away. But if the phone has been running for a few days it always says "searching for GPS" in Maps. Is there something I can flash to make it lock on quicker? So I dont have to restart my phone when I want to use GPS or Maps/Navigation? It has always done this on whatever ROM I flash.
I don't know if it will help with your situation or not but I use an app called GPS Test. Tons of useful info and such. Also allows updating of agps data. My GPS seems to lock quickly

Good luck

GPS test didnt do anything. I thought there was something that was posted that you could flash that would make it lock on faster? But I cant find it now. I always have to restart my phone to get driving directions in Navigation. But the thread did have to do with a-gps. i just cant find it...

There's a patch for HTC devices that uses an alternate data source for AGPS data. It *might* work on this phone-- I don't know why it wouldn't. Perhaps that's what you read.
Also, the updated Play store fixed an AGPS lock issue with HTC devices. Again, it appears this is only an HTC fix, but it could be what you came across elsewhere and are referencing above.
I haven't used "GPS Test", but there are two different apps named "GPS Status" in the play market. Both allow for AGPS location data to be refreshed, and produced satisfactory results on my HTC Sensation. They appear to be device agnostic, and would be worth a try. I went from a maximum fix of 4-6 satellites on my Sensation up to 12-15 satellites (under ideal circumstances).
Wifi and bluetooth can also cause occasional fix issues-- make sure both are turned off. I get massive GPS lock problems with Wifi turned on-- not so much with bluetooth.
I know this is a old thread but I thought it would be useful if I would share this. It was a fix for the Hercules but since its like our big brother (lol) I think it should work for our here blaze..

[Q] GPS Issues

From out of the box I've been having GPS issues. It won't get a lock when I use navigation. I've tried different places, different apps (waze and google maps) and different times (different days). If I restart the phone, it'll get a lock after about 10 seconds.
What would cause the GPS to not work unless the phone is restarted?
I contacted OnePlus and they all but told me to go screw myself. They suggested that I should walk around to get a GPS lock and if it persists that I should reset my phone. I reset my phone but all that did was waste two hours of my life re-installing apps and settings.
Any ideas? Anyone else with this issue? The phone is perfect besides this =(
Can't say I'm sure, as I haven't had any issues, except if I caused them. You let google apps have location access in the settings? Are you wake blocking any google location services?
+1 to what roxxorz said. If OP applied the workaround to Google Play Services and denied access to location it can cause a problem.
Also in addition to that make sure your location is set to "High Accuracy" as well as enabling WiFi.
Do note that when your phone is on High Accuracy it is draining the most battery.
I also have the same problem when I m on stock XNPH25R. Have to reboot in order to get a lock from the GPS.

But after I switch to nightlies, no such GPS issue, works like a charm.
I am actually on stock 30O cm11s and I have a GPS lock in two out three seconds. Try to download GPS status app from Google play

Sorry I'm a complete noob when it comes to the advance stuff. I know nightlies are cyanogenmods quick version changes that may sometimes have small bugs, but never tried updating phone with nightlies. I've always just done the standard OTA updates on my previous phones.
GPS is always on high accurac. Surprisingly today, GPS was working like a charm. I haven't done anything that should affect this positive change.
What is wake locking?

It could be just a thing. Sometimes I'll have apps [maps] that'll lock up, like if they tried to connect and I stopped it / turned off data. At that point killing / force closing the app works.
Normally I'd say if you don't know, don't worry about it, but wake lock is where an app / process keeps the phone awake and keeps the phone from sleeping properly, which leads to more battery drain. Google play services is notorious for waking the device for nonsense, so more advanced users block it. If you have no issues, I'd recommend leaving it alone.
Same problem here

I'm seeing the same thing. GPS was working fine for a week or so, but when I went to use Waze this morning it wouldn't get a lock. GPSTools showed satellites, but wouldn't lock either. Reboot fixed it. A few hours later, same problem. Reboot once again fixed it. This is all stock.
I don't have anything to suggest, but wanted to add to the evidence that there is a problem.
I did install a couple of apps from the app store between the last time I saw the GPS work normally and this morning, so I'll try uninstalling them to see if that helps. I killed them from the task manager, but that didn't help.

Sorry to hear you're having trouble too, but glad I'm not going nuts. You're only the second person I've read that has the same issue I have. OnePlus support was of no help nor did they admit that the issue was real. I hope they'll figure this one out, cause I can't.
Please vote on this issue in CM's bugtracker: https://jira.cyanogenmod.org/browse/BACON-115
Hints
Here's some new data. As I mentioned, my GPS was working fine up until a few days ago. In those few days, I installed 2 apps: "UP", by Jawbone, and "MyFitnessPal". Both of them use the GPS for some sort of logging.
Anyway, this morning I installed "AppOps" from the App Store. It's the one by Sylvain Galand, and the package is fr.slvn.appops. It doesn't need root, apparently. I used that to disable location access from both UP and MyFitnessPal. Since then, my GPS has been working fine again.
I think there's something broken under the LocationManager implementation in this version of Cyanogen. Seems like some apps are able to break it somehow. The other thread about this subject points fingers at Dragon Dictate, too. Whatever it is, apps shouldn't be able to wedge a system service like this.

I honestly hope that they at the very least acknowledge that this issue exists. GPS Navigation is a primary use for mobile. I haven't installed anything that would break location. All I Have is Waze and Google.
