I have been having problems with gps and my nexus. It seems like whenever the phone sleeps the gps either turns off or reduces power. I'm wondering if there is a way either with an app or with a different ROM that I can prevent this from happening. Is there maybe a ROM that's better for GPS? Right now I'm running AOKP build 32 with the included Kernal. This issue is absolutely driving me crazy. I run or hike nearly everyday and I need a way to track my workouts without having to carry a stand alone gps unit. Any advice would be greatly appreciated.
Google navigation is one of the best GPS services I've ever used

Thanks but I'm not having a problem with Google nav. The problem is the phone killing or slowing down the GPS. Google nav is no help for tracking long runs or hikes.

Have you tried My Tracks?

It worked just fine when I used it with a Motorola Milestone, even with screen off, never tried it with Galaxy Nexus...

Hi Guys,
Just wanted to let you know that my GPS seems to work fine now. All I did was to start the GPS Test app and chose 'clear AGPS'. Since then, I get a much faster GPS signal and it's even working indoors. It may as well be an illusion, but you might want to give it a try... Cheers, Andy.

Not tried the GPS Test App...
But I have used the Fasterfix and GPS Status Apps free from the Apps Market...
My GPS seems to get a fix within 10-20secs depending on location...
GPS Status & Toolbox works like a charm
For a long, long time I had been trying loads of solutions to why my GPS would never lock! Today, after doing a search here and reading about people complaining about cases blocking the signal, I tried to remove the case and got a lock right away! God damnit...
I can't believe a simple hard rubber case is blocking the signal completely.
It also depends on the way you hold it, don't block the gps receiver at the bottom and it seems to lock faster, I used to not be able to get a lock on at all until I tried holding it differently and it actually got a lock! Although it is a bit of a hassle but it seems to do the job
I had this situation:
my battery used to work as always (max 20h). One day it started lasting the double (AHD Revolution 5.1.9, MJD's kernel V22 or so) and I was incredibly surprised and happy. A few days later I find myself with the GPS not working. I batterypulled my device while using the GPS and it fixed itself but since that I lost my wonderful battery life... is it normal?
Poochie, are you sure that you did not simply disable GPS (lower battery usage) and enable it again with the reboot?

Yes, I'm sure, I never disable it because I believe it does not matter if you don't use gps apps.

I must say, I love my T989 except for the GPS. It is by far the best phone I have ever owned.
Problem is, I use GPS daily for my job. The GPS just always seems to be problematic in that while driving, using Google Navigation, the GPS signal randomly drops out. I will be driving, and miss a turn because the GPS seemingly lost signal, then after 30-90 seconds, it regains signal and the Navigation catches up. The entire time I am driving, the blue circle around the blue arrow in google navigation seems pretty big. This circle indicates how accurate the GPS is and it seems I never get really good accuracy. It seems like I just get low GPS locking ability and thus it's not always exactly accurate and frequently drops for a 30-90 seconds.
I have tried Jedi Knight ROM based on 4.0.4 and it was the worst, nearly unusable, took forever to lock and dropped a lot.
I am now using Jedi Mind Trick based on 4.0.3 and it seems to lock decently fast, but still never gets entirely accurate like my HTC phones all did, and it still drops for 30-90 seconds often, making it very hard to rely on for Navigation.
Many times I have flashed AGPS.zip and that helps lock faster, but the GPS still drops often and never seems to get reliably accurate.
I know this fixes it for many, and has made Jedi Mind Trick usable for me, but still not very dependable.
Does this phone just have a crappy GPS Receiver?
I haven't tried roms before 4.0.3, did GPS work better on earlier versions, or before ICS?
Is there any roms I should try that might work better with GPS Navigation?
Anyone using GPS daily without any drops at all? If so, what ROM?
Should I try different Radios or something?

aGPS patch works wonders. Which version of it are you using?

Google Specific 3.1 No SSL
That was the only thing that got my GPS usable.
It now locks fast, but just doesn't seem to ever have a strong signal and is very prone to dropping out.
Try downloading the "GPS status" app from the play store. Hit menu>tools>manage A-GPS> and Download.

I had similar problems with jmt and other ROMs, even after trying several of the GPS fixes.
I've been using cm10 nightly 10/12 build now and GPS is perfect, nearly instant locks and no drops during navigation.
The only downside I've found is battery life, its not horrible but its no jmt either. Expect 12-16 hour battery life.
To me, jellybean offers so much that I'm willing to forgive battery life for the first time.
Hope his helps

I dont know why some of you have issue with GPS. The issue is not from the rom. I think your phone might be in a bad batch or your GPS files are not set up correctly.
For me, GPS on our phone is very great. It locks fast and never loses signal. The accuracy is within 20 feet.

No, it is the ROM. With every ROM flash GPS files get over written but never cleaned up. I constantly have to flash the aGPS fix to get GPS back. That goes for every other android phone I've owned too.

I also use the GPS almost daily to track my runs with Endomondo application, and sometimes specially when running slow the GPS gets fixed to a location and will not update until 15-30 seconds after, maybe the same happens to you when driving in the city and you are very slow.
There is a feature called "GPS Static Navigation" that Samsung disabled by default in some of their phones, basically on the ones using a SirfIV GPS Chipset. The problem here is that our phone (SGH-T989) does not us that type of GPS Chip(set).
I've been trying to find a way to know the status of the GPS Static Navigation in our phone, but I haven't found anything about it just the info got from pdadb.net which is the following;
Satellite-Navigation
Built-in;GPS_module: Supported
GPSrotocol: NMEA 0183
GPS_Antenna: Internal antenna
Complementary-GPS;Services: Assisted GPS, QuickGPS, Geotagging, Simultaneous GPS
Navigation:Chip(set): Qualcomm gpsOne
Since this Chip(set) works with Assisted GPS, trying GPS Status application from Google Market and going to Menu / Tools / Manage A-GPS state / Download; it will help you a little bit since it will download the A-GPS XTRA Data (works better and faster if you do it while using Wi-Fi) that will help GPS to lock faster and get accurate positioning while on the road, it will last some days but it is not a definitive solution.
I still researching on knowing more about how "GPS Static Navigation" works in our phone, I even opened a question discussion about it @ http://forum.xda-developers.com/showthread.php?t=1940294
Please let me know if some of you know more about this,
Thanks, and hope this give you a bit more insights about it!

That's weird. I have flashed jedi, AOKP, CM, and i never had problem with GPS. I also own Galaxy S 4G, which has a crappy GPS due to the hardware failure. No Rom or app can fix that. That's why i think it is not Rom issue.

Was stock rom GPS any good? Try stock first and go from there to pinpoint issue

I had the Vibrant S and I know what youre saying!
I agree that it's possibly your GPS at fault. I've tried multiple ROMs (using Jedi Mind Trick X now) and have always very fast GPS lock and great accuracy when using ICS ROMs.
Something on my Gnex is going GPS crazy today after the 4.2 upgrade. I've tried disabling Google Now, checking logcats for likely suspects, freezing various apps, but I can't narrow it down. It's causing battery drain and preventing deep sleep. Any ideas how to figure out which app has been calling for GPS so frequently?
Sent from my Galaxy Nexus using Tapatalk 2
Yeah my GPS won't even lock after I did the upgrade yesterday. I dropped my phone also so that could be the reason idk
I still don't know which app is responsible, but I realized I've been getting constant data dropouts today. Every time data comes back, the GPS icon pops up for a little while. Tried flashing the H1 radio and I'll see how it goes tomorrow.

Bump. Is there ANY way on Android to track down which app is responsible for firing up the GPS?
Hello
I'd like to get started contributing to OpenStreetMap using my Galaxy Nexus running the stock 4.2.1 (JOP40D.I9250XWMA2).
I keep the GPS feature disabled because it drains the battery, but it can take several minutes to sync up while in the city before I can take a picture and have it tagged with the location
What could I try to speed things up? Connect an external (A)GPS chip through the USB port? Move to CyanogenMod?
Thank you.

I think move to a custom rom cant speed up your gps.
But an external GPS can help you.
At least part of the problem is that you keep the GPS off normally. So every time you turn it on, it has to obtain a cold start, which takes a lot longer than a hot start. Leave the GPS on and it should obtain a fix much faster.
Leaving the GPS toggled on in Android does not mean it's being utilized. If it's not being utilized, it's not draining battery. If it's being utilized, you should see the GPS icon in your notification bar.
It's been a long standing myth that leaving it toggled off magically saves battery. If leaving it toggled on is draining your battery when you're not using it, you have a rogue app that is using the GPS.

Thanks for the tip. I moved from stock Android to Cyanogenmod over the week-end, and will give Fasterfix a shot.
BTW, recently, while still using Android 4.2.1 and travelling to a neighboring European country, even after connecting to a local wifi hotspot and using GPS Status' Reset + Download features, I noticed two issues:
GPS didn't lock for hours even while being outside the whole time
When it did lock, it didn't keep track and was stuck where it was
As a result, GPS was pretty much useless.
What could be the cause for this? Aren't AGPS data supposed to let me lock faster? Will Fasterfix solve the issue?
Thank you.
Can anyone confirm random phone reboots while using GPS for long time? I experience it regulary. After and hour and half or two hours of using GPS (either in car for navigation, charging/not charging) or on bike for tracking (screen off) with endomondo).
I'm going slightly mad because of this. I thought initially that the phone gets overheated with charger, but it reboots even with screen off, not charging). My other guess was the navigation application, but it happens also with sports trackers (endomondo, strava). So definitely it must be a problem of GPS driver or hardware. I tried various ROMs, CM10 or .211 or .96 ports, but it happens all the time.
Does anyone have more info or in the best case a solution for this? Thanks a lot!
I gave it some more thoughts. I use GPS Status with permanent notification with status details constantly being updated. I uninstalled it today, maybe this was the issue. Please, can anyone confirm that GPS Status is the cause of problems or that GPS Status is working fine even for few hours of gps activity? Thanks
same problem
Hi,
i have two xperia ion with the same problem. When i use GPS for tracking on my bicycle with locusmaps or oruxmaps it alway reboots after a while, it works maybe 30 minutes or one hour but then it reboots. The same with Navigon navigation, always reboot after about 30 minutes. Both smartphones the same problem. Running on Android 4.1.2, i downgraded the phone to ics 4.0.4 but the problem was still the same.
Did you solve that problem??
Thanks
Peter
