[Q] GPS Issues - ONE Q&A, Help & Troubleshooting

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.

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.

Please Fix My GPS

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.

[Q] Wifi & network location unavailable after switching location off & on again

[Q] Wifi & network location unavailable after switching location off & on again
Hi there,
I found this strange but reproduceable bug on my N5's location services and was wondering if it's the same for you.
Turn off location via settings or quick settings
Turn it back on
You'll be asked to accept Google location terms
Switch to battery saving mode (only wifi & network, no GPS)
After these steps, my N5 cannot find it's location via Wifi & mobile network anymore. In Maps it might still show the blue dot but moving around it won't update. When using any other app which will try to get a fresh location it's a no go. Like Google+, try and make a post with location, no joy.
I have to reboot to get it working again.
Did you agree to those Google terms? If not that's the reason...

I agreed to those of course. If you cancel that it will turn back to device (GPS) only

Strange. Are you running stock ROM? I had no problem doing the thing you described.

Just got it 2 weeks ago, all is stock, locked and original.
Did you try any other app besides Maps? That sometimes uses last known location and shows blue icon.

You're right, mine also won't find my position without GPS. However a reboot fixes it for me.
Somewhat glad to see others having this bug too. Indeed a reboot fixes it right up so it's not a huge deal.
Under normal circumstances I would't change this setting ever, but when I just got my N5 I wanted to test the GPS only feature. After turning it back to Battery saver I noticed and started investigating what caused it.
Thanks for testing mate!

No problem. I'm glad also to be aware of it now, so that I can avoid standing somewhere I need and it won't find it
Anyone else willing to try this? The N5 from a friend of mine did not show this behavior. And another did. Weird bug.

I have the problem on my 16 GB black nexus 5 with stock Rom and no root. I tested with dalvik and art but the problem exist. I have found 3 solutions:
1- reboot phone (temporary solution)
2- stop Google Play Services (temporary solution)
3- uninstall updates of Google Play Services use with stock/no update (permanent solution)
one more thing; when I can't get a location fix with network/wireless GPS mode on Google Maps or any other application, I can see a circle on " Yandex Navigation" that shows my location.
but more interesting thing is I can see a circle that shows my location on Yandex Navigation when my GPS is completely off.
I think this problem is about Google Play Services or Google Location Services. I hope someone find a solution.

Thanks for your (rigorous :good tests.
Reboot was the one I used to fix it, didn't know about the others you found.
In a strange way glad to see it's a software bug, which means it's fixable. I guess the friend I mentioned has not updated the Play services ever, that would explain why he is not affected.
happens to me as well on a Nexus 7 (2013). I've found that battery drains faster even when in deep sleep
Me and my colleague also have this issue...
Completely wiped and factory reset to stock, same prob.
Reboot solves it until you turn location services off and on again, or go from "device only" mode to "battery saving".
A quicker way then reboot (reboot actually does the same as this step) is go to settings, apps, running, Google Services (you might have 2), there STOP the GoogleLocationService (it will stop and reload the service)
Location should work again in battery saving mode...
Thanks for that one Foggy79!
Reboot or restarting the google play services takes much longer (especially when you have to disable ADM first) then your trick of only stopping the only location service.

No problem.
I just reproduced the issue on an other colleague's N5, that makes 3 ppl here in the office, can't be coincidence.
If the GoogleLocationService could restart automatically when you turn on "Location" and agree the terms, that would be great...

It appears the issue is fixed for me.
I have Google Play services 4.3.24 so it might be fixed behind our backs.
Now when you turn the location off and on again, the GoogleLocationService is automaticly restarted also
Fixed for me as well with the new Google Play Services!
The new version now indeed restarts the LocationService again.
I'm glad Google also reads XDA (j/k)
Now if they can get GoogleLocationsManager and NlpLocationsReciever to stop running when Locations Services are turned off completely, that'd be great.

Help: GPS is wonky

My phone is 100% stock. I have noticed that sometimes when I go to use GPS, I fail to get a fix, or I get a fix on a location that is between 500 ft and 20 miles away. I first noticed the problem in Google Maps, but I believe that all other GPS-using applications have the same problem. I first noticed this perhaps a few weeks ago. When it gets into this mode, it will usually resolve itself after 1-20 minutes of continuous use.
I've downloaded both the "GPS Test" and "GPS Status" apps and had several thoughts:
1) I thought this might be related to data in Google Maps. I deleted all the data and cache from the Settings->Application. No difference.
2) I reset and re-downloaded the AGPS information. I initially thought this made a difference, but I no longer think so.
3) Sometimes rebooting seems to resolve the problem.
4) I thought maybe some hardware was damaged causing me to get a weak signal, but in one case where it was unable to get a fix it actually saw at least 10 satellites, probably at least 6 of those had a "green" (30+ dB SNR)
5) I thought the problem is initiated by going into Google Maps and the other applications worked so long as you didn't go into Google Maps. I no longer believed that.
6) I've set location services to device only as well as high accuracy. I don't see a difference.
I think I've had similar problems in the past and recall fixing it somehow (in software) -- but I can't figure out what was done.
HELP!
I'm on a custom rom and have noticed the same thing within the past couple of weeks. It used to be fine, but now it can way over a minute to get GPS lock. Sometimes it thinks I'm still where I was a long time ago or somewhere completely different. This is in google maps too. Waze also has trouble locking on frequently now so I doubt it's an app issue.

I've had it take 10-20 minutes in some cases, it always reports a location within 30 miles of me, but that's still way too far to be helpful. I've sometimes had it report locations within a half mile of me and that's still equally useless. Once locked, it seems to stay locked. for my entire usage, will later be off, even if you start at the same location you last used it (i.e. use Google Maps to drive somewhere, and then leave a couple hours later using Google Maps).
The other really weird thing about this is that I had initially thought there was maybe a problem with the GPS receiver itself, like the antenna was damaged or the feedline between the antenna and the receiver, etc. But I've gone into GPS Status or GPS Test applications and it gives SNRs from each satellite, and its got adequate SNR from enough satellites to get a 3D fix even when it doesn't have one, which implies its something goofy in the software somewhere.
It does seem to have gotten better in the last few days, maybe?
I'm not entirely sure what the problem is. I did change my battery out personally a couple of months back. I was wondering if I may have damaged something. As far as GPS fix and those other apps, yes it does lock on, but it does take a little longer than I would take to lock on. Mine sometimes takes quite a while, like 5 minutes+ like yours to fix too.
