[Q] CM9 R800x Non-GPS location services not working?

I've flashed chevyowners' FXP CM9 builds onto my R800x, starting with 112, currently on 113. I only seem to be able to get a location if I turn on GPS. If I have it turned off, I am unable to get a location at all, and google maps asks me to "please enable a My Location source in system settings.
But in Settings -> Location Services, I have Google's location service checked, which should give me coarse location from wifi/3g, right?
I used the 3/17/12 gapps.
Does anyone else have this problem? Anyone know a fix? Do any of the other CM9 compatible kernels (Such as Darkforest) fix the issue?

Yeah, it's a bug Chevy needs to fix.

It's not a kernel issue, it's a cm9 issue that's already known and they are working on fixing

Chevy isn't a part of fxp. All he does it make fxp usable for cdma users

Cool, wasn't sure if it was a Play specific or CM9 overall bug. I'll check out the CM9 issue tracker.

Hey,
I have a similar issue (the same?) with CM7.2 (FXP114) on my Xperia Mini Pro (mango):

Yup, it's fixed. I can pull locations from all 3 sources now - GPS, Wifi, and Cell towers.

Sweet, thanks for the hint, I'll try FXP115 this weekend.
However, WiFi location only works with google maps, right? Or does it work without gapps as well? If so, how, and with what app?

Dunno. All I know is I'm getting locations in all the apps I use them in (gmaps, weather.com, touchtunes), with both wifi on and off while GPS is off.

Network location needs an apk from gapps, see here:

Solved my issue...

Are there any custom roms that support wifi location services?

I'm trying to use some of those apps like foursquare or the ones that show you people running the same app near by like Grindr. With the stock OS it doesnt' work at all. I've tried a few custom roms but they don't seem to either. Even in CM9 if I enable location services the apps still complain that there are none. Are there any roms that are better at it than others? Things like google maps usually but not sure if some of these apps are looking for GPS only and that's why they're complaining or what their issue is. Thanks!

Kindle Fire lacks onboard GPS module, and some apps require high precision location providers to work.
I think that wifi location service isn't considered high precision location provider from Android' APIs.
The only way to enable those apps is connecting a GPS device to the KF and have a kernel that supports it.
You might also want to try "tethergps" look for it in google.
Anyway, this post should be moved to "Kindle Fire Q&A" I think...
Bye!

On cm7 you could use just the wifi signal for Google Maps but it doesn't work on cm9, hopefully someone can figure it out so that it will work.

Modaco rom supports network location and it works much better than I expected. Of course you can't use navigation with it, but other than that, all location based applications work fine.

I used Unofficial CM9 and the browser and Google Maps could use wifi to detect my location. Not sure about FourSquare or 3rd party apps though.

I'm on stock and mapquest finds my location perfectly (and with good accuracy)

Wifi location services seems a little funky...
On my Galaxy Note:
If I turn off GPS in Settings, network location services all continue working normally.
On the Fire running CM9:
If I turn off GPS in Settings, it acts as if wifi location services have also been disabled. If GPS is set to on, wifi location works in Google Maps, but not in Foursquare (it just hangs forever waiting for location).
Probably something in the frameworks needs a little rework to handle a wifi-only device with no GPS...

It works in gede

Hashcode's new kernel should have WiFi location support:

Nothing to do with the kernel, it's in /system

The newest build of gedeROM supports using wifi to pinpoint your location

I'm running MoDaCo Gr8 ROM and Google Earth and Maps pinpoint my location by wifi.

[Q] GPS Tracking 4.2

I am running the latest build from Muzzy for the Sprint Galaxy Nexus currently released yesterday. OS V 4.2.1
I am not having any issues with GPS locking in but when I try to use the Sprint Family Locator app, I am unable to locate my son's phone also on the same rom. I get a general network based location but cannot get a GPS location. I flashed his phone back to the stock 4.1.1 image from Google and the problem went away. It's as if the app cannot request a precise GPS location. Any thoughts?
I love the new builds and would hate to go back to stock but being able to keep tabs on my child is important. Knowing he is within a 1200 ft raduis is funny but not helpful LOL

Fixed?
You posted this a while ago and I was just wondering if you ran into a fix?
I am running a 4.2.1 rom and my GPS locks onto satellites but the tracking is way off.
I use a workout tracking app that worked fine but after my update to a 4.2.1 rom the tracking is not working.
I tried multiple workout trackers and all are having the same problem.
I know for a fact that my route is 15 miles, but the trackers now report I've gone on a 190+ mile trip...

I have problems with GPS on a different ROM but when I turn on both settings in location access it works fine.
I don't like to use the allow Google to collect my data but give it a try its the allow WiFi and mobile network location.

GPS locking up

I was just wondering if anybody has been having this issue. After successfully locking onto satellites for GPS for navigation, if I turn off maps when I reach my destination, it requires a reboot until I can use GPS again, it only updates once every few minutes. Haven't done much testing on it since I was on a highway going 80 when I noticed

Same issue here. I think its wide spread but only a few of us use the GPS function

yup
Happened when i pushed the second update (twice). I'm hoping for a fix soon.

Same here!

Same here... even exchanged for a new device from 16 to 32gb model and still the same issue. Works for about 10-30mins then locks me in the location completely.
Moderator should merge threads.... issue is duped on XDA

This seems to be a legitimate issue. Has anyone reported the bug to Google?

HERES THE FIX!!
I had this very same issue, and found a resolution for it (can't remember the source now)
After taking both system updates and rebooting, it is necessary to hard reset the device. Upon the initial boot, you must leave all options checked but the following -
Backup and Restore options (you can turn on after the initial setup is finished from options)
there are three location options, one being new to 4.3 and what I believe to cause this - it mentions the ability for location to be grabbed when the screen is off. You must diable this option.
Finish installation, and then you will have properly working GPS.
Here's how I'm quantifying that - before when I was in the exact same boat as those in this thread, I would open GPS test, and I could see 7 or 8 sats in view, but it wouldn't lock. Or if it did, it would work for a short period of time, and then bomb out. I drove around the city for a few hours yesterday using the GPS so we're near and dear now to each other.
After doing all this - you will IMMEDIATELY see 20 sats available upon launching gps test and then almost immediately get full lock and keep it that way.
Was a pain that I had to clear everything, but now GPS is working as I would expect it, and I've not had any issues getting full lock, even in my basement.
Hope this helps!!

I tried to duplicate the problem you describe, but was not able to.
Here is what I did:
- Launch Maps application for the first time.
- Accepted the terms of service and enabled location services access, including Wi-Fi.
- Got location via Wi-Fi, then pinpointed the location via GPS.
- Back to home screen -> Settings -> Apps.
- Maps was not running, but I went into Maps under the all apps view and force closed it.
- Back to home screen.
- Launch the Maps application again and I had an accurate location via GPS in less than 10 seconds.
I repeated this procedure again with the same results. I then disabled Wi-Fi location assistance so that only GPS was available. Repeating the tests twice again and I still see the same results. I have no problems getting a good location lock quickly.
I am running the stock firmware, build JSS15J, and Maps v7.0.1.
I am happy to test again if somebody having this problem can provide specific information regarding their test procedures and results.

It was showing an accurate location in Maps until I started to drive. Once I sped up, it showed me where I was ~15 miles back

Thanks, I'll try this when I get back to a decent data connection
Sent from my Nexus 4 using Tapatalk 2

I was the source #1, AND #2 although I thought this fixed it, the issue came back! Its like a memory error with the gps driver and or buffer with a overstack flow of data and it either crashes it so you loose gps functions, or locks it up so its searching but never locks. Seems as if its software and android 4.3 or google system service or framework issues. Same problem with older S4 chipsets and jellybean. Google fixed that by updating system files for jelly bean 4.1.2 and 4.2.x. Also the new maps could be the culprit as well since it was updated to a completely new version.

I had done a hard reset as well after applying the initial updates. I left backup enabled but disabled restore during the setup process and disabled all three location features as well.

Yes you were, I remember your username now. Thanks skyhawk21! You resolved this for me. I used my N7 for a few hours in the car yesterday, and it was spotty and crappy in clear weather for a while, I did a reset in the car like you mentioned, and everything now has been working solidly since. Thanks again.
The last part is sad to hear. I however have used it for several hours straight with no issues, so I'm hoping it stays strong.

I am confused, so should I reset mm y tablet? Will that actually fix GPS?

It will fix it for awhile but the issues creeps back up.... good luck this new nexus 7 is turning to be into a nightmare, flaky gps and flaky touch screen issues on two fo them now!

As long as you only use google maps it seems to work ok.
Once you start using other GPS apps (GPS Test, Gas Buddy, Google Earth) the problem shows up eventually.
It might have to do with multiple apps accessing GPS, but that is just a guess.
I wouldn't bother factory resetting (for the N7 2013 GPS issue). Reboot has always allowed the unit to get locks again (for me) It feels like an OS or driver problem.

I found a posting on AndroidCentral about the same issue. According to one of the posters, the issue is known by Google and an OTA should be pushed out soon for it. I just hope its true because I'm pretty dependant on my N7 for finding my way around town

I must be lucky, I've used it for several more hours, and still rock solid GPS at all times.

hmmmmm gps wasn't locking earlier then decided to do a soft reset, now it's working. I just have to try it later when i drive home and see what's up.

Anyone have problems with GPS?

I cnat seem to get GPS to lock on. It always says searching for GPS on maps, and on waze it just says it can't get a GPS signal.
I'm on liquid smooth 4/13, and quantum kernel 4/18.
I tried messing with some build.prop setting like the gprsclass and others and nothing will fix it. I even updated the gps with android tweaker 2 from the play store.
Anyone have any insight I need gps for my new job.

I lost mine when going from a cm11 nightly back to a 4.3 TW rom. The only way to get it back that worked for me was to flash a backup that had gps working, get a lock on my location and then clean flash back to the other rom.
