[Q] GPS stopped working! - LG Optimus G (International)

please help. on my LG Optimus G e975 stopped working GPS. I initially thought that this due to custom firmware. but when I got back to the official firmware and it does not work ( I also edited gps.conf under my region, also tried various programs to find satellites-nothing helped. satellites no catches at all! maybe someone encountered this problem and can help will be very happy! Sorry for bad english (

Same problem on F180K, Tried different Stock roms and gps.conf, no effect.

I'm 3rd.....same problems...no gps lock.Although in copilot live i get "GPS signal is found, determine the location" message,it get's stuck like this for ever.I tried anything i could think of,nothing worked. I guess i'll just send it to warranty.

Hmm... Interesting. Just out of the blue? What exact model is your phone? Looks like we already have reports on E975 and F180. I have strange things happening with my F180's GPS sometimes, like reported lock on a single satellite (physically impossible), but generally it works well (and I hope it keeps working)...

E975. Now running on stock...

what actions you have recovered GPS?

I didn't. Gps won't work,no matter what i try. Like i said,i'll send it to warranty.

What application are you using to check your GPS? I don't know if mine is working, on Maps, it detects where I am. And I also can locate it through Device Location Manager. Please clarify if what I am saying is related to this query. Thanks.

There are some good apps that show you the detailed status of your GPS system, including the number of sats, A-GPS data availability, exact coordinates, positioning error, time to fix, etc. The one shown on the screenshot in [email protected]'s post is GPS Status & Toolbox, I use it all the time. Another good one is AndroiTS GPS Test. Yet another is GPS Essentials. Just search on Play Store...

BTW, just out of curiocity... Since nothing seems to work, as you said, how long is "forever"? I mean, what is the longest time you left the phone waiting for a fix? Theoretically, a cold start of a GPS receiver can take up to 12-15 min (if I recall correctly) to the first fix, or even longer for some receivers that do a wide PRN search on cold start. So, I wonder what happens after leaving the phone's GPS waiting for about 20 min or so? I would think if it doesn't get a fix after that long, you can conclude it's most probably a receiver's problem. Just thinking out loud here...

Installed the GPS test apps, AndroiTS GPS Test and it is really taking too long determining my GPS Status.

I let it outside,for more than 30 minutes. My gf's arc made the cold lock in less than 1 minute. When i first got the phone,it made the cold lock in about 10 seconds. I was amazed. It was the fastest lock ever. I'll try the apps you mentioned. About google maps,it is irrelevant,because it's using data. I tried gps fix and gps status pro. Nothing worked. Again,on arc s it fixed in less than a minute. I'm starting to think it's hardware.

I am also now worrying if it's with the hardware. Does that mean that most OG units have damaged/problematic GPS sensor? Is it software or really hardware related? I was at first confident that mine is working, since Maps can detect my location.

Technically, in that time it should get a lock even if it really was a true cold start (no A-GPS data, no almanac, no ephemeris)... Did something happen around the time you lost the GPS? New ROM flash, possible physical damage, anything? I am not an expert in this by any means, just trying to apply some logic and common sense -- I am pretty sure you went through all that yourself... GPS on phones is weird sometimes. I had a couple of phones (Samsung i8000 and LG P990) that totally lost GPS lock with some particular ROMs, but went back to normal after flashing another ROM. I also had to reboot my SGS2 several times to get GPS locking again. And all the apps I know that are made to improve the time to fix are only changing GPS configs to set the NTP server and the Xtra server for A-GPS data, that's pretty much it...

I know ,and one of the best app is gps fix.
About the issue, don't know when it appeared. I even try to do a hard reset from hidden menu,nothing worked. all gps tests from the same hidden menu are negative. No phisical problems(never dropped the phone, it's well protected). I think monday i'll send it to warranty. If i'm lucky enough, i might get a G2 instead,because my carrier won't sell G no more . It happened in the past, i have friend who got their galaxy s2 replaced with the S3 . I think this is possible, because i payed the same amount of money for the G in march,at the same monthly fee(320 euros). So, wish me luck .

Could you please help me, I have the same problem, I have already tried many stock roms, but no gps yet. I thought it is a hardware problem but then it seems not. Write me please which kind of rom have the service flashed. Do you know what did they different as you? Thank you very much.

They were not finding any satellite...
later with the help of @superstick1 & @blbean i was fixed it... now these apk finds even 7 satellites!!!!(often LOL)
but Navigation continues without work.... some suggestion?
i was tested:
1-reinstall the apk. (not fixed my problem)

3-fix gps sat. with gps status(not solved)but 5 satellites found...
4-use FASTERFIX.apk and then restart my machine (not solved)

Hi SERGI.3210
We meet again. Lol. I notice from my own experience that if we often reboot our phone, the GPS state will be restarted. And hence it will take some time for the GPS to work again.
For example, I have once flashed LeeDrOid' v2.2.2 in the past few months(first time), and I got a fix very quickly. It will be within 5-15 seconds? At most it will take is 30 seconds. However, after I reboot for whatever reason(I forgot, but I am not flashing anything else), and the GPS takes more time to get a fix again. The situation got worsen when I am in the car to get a fix. Took about 5-10 minutes??
But after some time, tolerating such slow fix(I know, its annoying) it suddenly get back to normal again. Which means I can get a fix very fast again.
Many has recommended the use of GPS Status app to clear A-GPS data and then download them back again. It works for them it seems, but in some to a large extent, it did not really work for me.
Maybe you can try Ulysee Gizmos app from the market? It has the capability to download A-GPS data as well. Recently I try using it and it seems to fix my problem once again. When was it? Last two days ago. Lol. Now it still work fine. Hopefully this continues.
I am still use GPS Status to get A-GPS data. Which means I am using both of them at the same time. Probably both apps does fires out some solutions? Haha. Me not sure but you can try.
Cheers mate. =)

okay i´m going to test this:
-1-clear A-GPS data of the gps status.apk AGAIN....if not solves:
-2-download Ulyse gizmos.apk and try it...if not solves:
-3-I will go to area discovered to trying... if not solves... maybe i will go to reinstall the all the apk relationed with GPS..and if it not solves that
-4-I believe that I will think of burning my DHD.. lolololololol
thank´s for you usefuls posts man..
see you soon here
EDIT: i tried to install another GPS NAVIGATOR (sygic) BUT THE PROBLEM PERSISTS... i´m really sure that the problem its that my device finds gps when he wants And if it is clouded less still
I am fine here thanks. Getting ready for work now.
In your case, the problem is nothing to do with the navigation software but your GPS cannot get a fix. It may due to hardware failure.
If the situation persist, probably you should consider sending your device to HTC for a check. But make sure you turn back your phone into normal state first. (i.e. unroot your phone)
i pretty much have the same problem ...
5+ mins to lock my position ..
RcMixHD 5.5 and a changed radio... i will just burn it..

So you finally got a fix? Congrats!
Yea, try to send it to HTC for a check. By the way, again, remember to unroot your phone first before sending to them.

good night buddy!!!!
i have soo good noticesx100000000000
THAKE THIS:
gps status:found 8 or 9 sat.
fixed in 62 segs.
google maps:working perfectly!
finding gps at the moment
15 meters position error max. (better than my htc hero)
THE MEDICINE:
1--Though I feel sorry very much I had that flahs another CUSTOM ROM
2--Then I´VE flashed the recommended radio and was foun 3 or 4 sat...
3--and the most important: flash the RIL for this radio in this moment i was found 8 or 9 sat.!!!
the only one thing that i don´t like (nothing nothing) is the custom rom:
RCmix 6.1.0.1 (ported from desire s)
i´m COREDROID LOVER and RCMIX seems too simple but i preffer the good performance before beauty things...
Nevertheless when it does a few kilometres and tested well the GPS I will try with Leedroid (froyo) to see if I obtain the same results
Good for you buddy!
Usually if you got a fix pretty quick, it will have errors ranging to 30-50 meters(that is from what I obverse based on my device that locks within 5-15, max 30 seconds). Then it will adjust overtime. Well, still better than doesn't get a fix at all.
Hmm.. RCMis HD6.1.0.1? The Evolutionary Sense ROM? I have not try that yet.. plan to try after my exam. Currently concentrating on my exam for this month. Also quite satisfied with my current flashed LeeDrOid v2.2.3 ROM now. Lol.
Probably will be trying Miui too. I would prefer staying with Sense ROM as there is unlikely to have Premium Navigation in Non-sense ROM. If I would to try other GPS apps, I will have to pay for it. Premium Navigation is free for life for me in Malaysia + Singapore. Also finding addresses with it is easier, unlike other GPS app.(i.e. cannot search address). Probably due to the names of addresses here. Here uses Malay names and not English.

Already testing... I was already getting good GPS results on the EL29 ROM I built (even indoors). This mod is really just another gps.conf edit.
I installed the mod over an hour ago, reset agps data, rebooted and got a pretty quick lock (indoors) immediately. I just tried again and it's not getting a lock at all. I think I'll go back to the original gps.conf and see if it locks properly.
Update: After reverting back to the original gps.conf, clearing agps data, and rebooting, I got a lock in 5-6 seconds. I think part of the issue is that this is now hitting "derekgordon.com" instead of the regular GPS servers. This mod was sent out to the interwebs and I'm sure there are TONS of people installing. I'm not sure if the server is overloaded or whatnot, but I don't want to rely on someone's private website for my Navigation and other GPS needs.
Code:
NTP_SERVER=ntp.derekgordon.com
AGPS=http://derekgordon.com/gps-files/bin/xtra.bin

i already get decent gps as well but this mod has me curious.
i totally agree with you about not wanting to rely on someones personal server.. though only v3+ includes this server. there are older mods that rely on qualcomms servers.
I tried this mod (V3) and it made no difference for me.. I'm afraid my GPS problems are hardware related, I've tried almost every 'fix' available.
Well it probably has to be manipulated to work with our device. The file is for the international sgs2

...i wish u didnt say that...because my gps is fukked...i was hoping this patch would fix it but if i end up being in the same boat as you where its a hardware problem ill just take it into sprint...i havent done it yet partially because i am hopeful that i can fix it too lazy to go and scared they r gunna find out i rooted my phone even tho ill rest it back to stock
I'm getting my hardware replacement this Friday. I've done everything from scripts, to gps drivers, nothing is consistent. Even reverting back to stock didn't do anything.
Hopefully it will fix it.
I tested this today. Before the fix I couldn't get more than 3 satellites in GPS Status, after the fix I got 9.
Also noticed that while navigating I could get a lock in under a minute instead of 5+ minutes before the fix.

Mine is stuck on roaming after flashing, weird
Edit: fixed now, no idea what caused it but fine now
Gps crazy fixed now too
loaded the new config file last night and day later it still won't get a lock. i guess this mod isn't for me.
edit: after few reboots it gets lock in under 5 seconds... hope it stays that way

Is it possible for someone to upload the original gps.conf ?
I lost mine after trying many different modes, to get the damn gps working lol.
Here's my stock gps.conf from /etc/
It may help some but I know that some of the phones have bad gps chips in them. My first one did. I had to get it replaced in order to get a gps lock. The first one I had would never see more than 1 sattelite and never lock. Nothing I did or that the sprint techs did could change it so they swapped it out for me.

on stock rom I never got a lock, neither on rootbox(I also tried to edit the gps. conf and those stuffs, but nothing helped) , but with cm10 and cm10.1 it locks in seconds if I'm on the street, however it shows that only 2 sattelites can be seen. But my position is accurate

I think 3 sats are needed to work gps, I think your device use wifi to get your location, try to disable, and it wont work IMHO.

you're wrong, it locks up quickly without wifi and I can use it (sygic) for navigation as well. However as you can see it shows only 2 sattelites
mine works only when wifi enable, mine sees 2 sats sometime, but still no position. When I enable wifi location ( without wifi enable) it shows instantly my current location.

cm10.1-m3, litekernel, i927RUXKJ5 baseband.
You need 4 sats to get position, even in 2dimension (plane) you need distance from 3 points, because 2 cycle will have 2 intersection.
please european guys, respond the cuestion, only that way can find a solution together..
bubor, you think the problem is caused by the kernel or the rom?? or maybe our devices are defective? :crying:

I'm using this spyke's guy cm rom with the kernel from kick buckowsky's pacman thread. But before I flashed that it worked with the original (lite) kernel. Again, it worked with the old dman's cm rom, but not with rootbox and never with any stock rom (ics nor gb). Modifying the surfgps and gps.conf has never really helped.
Sometimes (its really not typical) I simply dont get a lock now either, but after a reboot it works fine.(be sure to test it outdoors, under a roof it's really weak). I use sygic for navigation (it has downloadable offline maps) and I live in hungary, but when I was in Prague, it worked there well,too. Mobile data needs to be on, and those ticks that I posted before.
I hope you'll get the gps working I know how annoying a useless gps is.
well i´ve just tested the rom PACMAN by kick buttowski, and for me gps works on it, but reports only 2 sats. I know that it is a cm 10.1 issue, which i don´t know if spyke is working on in his rom or not??. While i´ll wait for the spyke´s new kernel cause litekernel I think is draining the battery so much for my daily use.
So I gather the rom is what causes the gps problem? my phone is healthy uuffff :victory:
mine works only with "wifi and mobile network location" checked, and it shows my location very fast, so I'm happy with that.
I have no clue what needs for "mobile network location", but it does its job well, since I see maximum 2 sats, while I have my position.

Seeing 2 satellites is part of a bug. The NEMA messages, raw satellite data, aren't coming out of the driver properly in the latest build. So your software will always show that there are 2 satellites. That's incorrect.
Wifi location works because the GPS coordinates of the MAC addresses of nearby base-stations are known. When people have this feature enabled, the phone will silently upload MAC addresses and lat/long. It also uses cell tower triangulation (this was how the first google maps worked before common phones had GPS in the old blackberry days.)
You'll notice if you ever move (from one house to another) it will take Goog a while to figure out that your home wifi base station has new GPS coordinates.
If you're out in the middle of nowhere, you won't be able to get any kind of lock like this.
But, I'm fairly certain while these roms are not reporting correct NEMA, they are actually getting a real GPS lock.
In other words, software that asks the API "What's my lat/long and accuracy?" will get a valid answer.
Software that asks the API for "exact, raw satellite data, I'll figure it out myself" gets garbage.
It works for me (Italy).
I still have the 2 sats bug but it seems i get a lock in 30 secs.
I even tried with no wifi and no data connection: same result. I got a lock in 30 seconds.
I havent tried a navigation tho.
Hi guys, I'm in the u.k, and as far as I'm aware, the only person in the country with one of these phones!
But,, gps works fine for me.
The phone can see 12 satalites, and have a lock on 9 of them, giving me an accuracy of 16 feet.
Only problem is I don't know what rom I'm on as the chap rooted it for me before I got it sendt over.
I have no bugs in the rom that I've ever noticed, its 4.0.4 but that's all I know, anyone know how I can find out?
I'm guessing its stock ics, and as no other roms seem to be stable or ever finised, there doesn't seem to be any point in flashing anything else, accept maybee the litekernal which is the only stable one I could find.. but since I don't know what rom I'm running, I can't tell if the kernal will work, unless anyone else knows?

GPS program called "Automapa" - problem

This is my first post so hello to everyone.
First of all, i apologize for my bad english.
For about a month I`m a user of LG E975. Telephone is brilliant, but I have one issue.
I use very often GPS navigation, and I am used to use program called "Automapa".
This is a polish program. On my earlier device HTC HD 2 everything works fine, but
on LG E975 GPS Signal is very unstable. One time it is, but after a few second it`s vanished, and
the situation repeats. This is not dependent on the weather.
Other aplications, like tomtom, naviexpert, or google maps works fine.
Could anyone tell me what is the problem? Is the GPS reciver on LG so weak?
I would like to enclose the trial version, but I can`t do it without 10 posts,
so if anyone would like to help I can send the trail version by PM, or mail.
If anyone can test it, or solve the problem I`ll be grateful
Try gpsfix from market.
Maybe the app can't properly use the hardware.

I have tried Fasterfix and GPS Status&Toolbox from market.
Situation has not change.
I think that problem is deeper inside.

Did you root your phone. ....and what else you did kernel. ....rom ..recovery .....etc
You need to know that HTC devices use real aGPS assisted lock and top notch internal hardware. .

I have rooted phone, but still oryginal firmwere.
If there is a chance to improve gps working on other rooms I can try to change it.
I didn`t do it because everything else works fine for me on stock rom.
Is there a custom rom for LG E975 that works like a stock?
Im tired of changing roms on HTC HD2, I have changed about 30 roms on HD2.
I have bought LG to have some spare time
But if there is no other option I will do it

LG G2 GPS issue, observations and possible fix!

Hello everybody and glad to be part of this community.
First please excuse my English.
I recently bought an LG G2 LS980 ZVD kitkat 4.4.2 and notice that my GPS doesn't work, I tried every possible solution found in internet (not with flashing the device, because I'm like 2 days old in android ) even a peace of paper under the antenna.
I found a way to get my GPS work and get a lock in seconds but for the first start of the phone after a factory reset, if I restart the phone the GPS problem appear again.
So this what I did after baying the phone:
root the phone with iroot.
trying several solutions in internet(no luck).
factory reset.
set new configuration of the phone (language, name, email...).
let the update of google services inc complete.
let google hangout update.
disable GPS and enable it again(the phone ask me to accept the terms -->ok... here he ask me again that the localization services was disabled in a previous version of android, do you want to enable it-->ok...).
click on google maps (wifi is enable).
get a lock (fix) in seconds .
GPS test app: about 21 sat in view, about 12 sat in use :victory: .
For a month I thought that I fixed the problem until I restart my phone the problem return again. But I did the fallowing observation:
enable plane mode --> no GPS signal.
disable plane mode --> GPS test app and androits GPS app: getting about 8 sat in use, about 50 feet accuracy then signal freeze.
I reset my phone again, GPS work only for the first start again.
Any idea what does the phone do in the 2nd start after factory reset!!!
Thank you all.

If you want to rule out a software issue, use LG Flash tool and image your phone with a .tot file.
Here's a thread about it: http://forum.xda-developers.com/showthread.php?t=2702422
Get the ZVE version and flash it. This will wipe your ENTIRE phone of course.
If that doesn't fix it, it's a hardware issue.
Oh, and welcome to the community
If you're nervous about this method. Watch a Youtube video to good idea. Then follow the guide exactly, you'll be ok.

Thank you for your reply.
Sorry but I don't think that is a hardware issue, because I tested it within a month without restart, a week, and now a day... the 2nd restart will make the GPS problem if I'm correct...
For the ZVE .tot I will see how to proceed with flashing... thank you again, but before that can anyone confirm the GPS issue FIX in the ZVE version.
Thank you.

Well, the G2 doesn't have a great GPS. It wasn't an "issue" per se, but it is a problem that some have and others don't GPS works great for me on ZVE and ZVG (Lollipop). ZVE is the latest Kitkat release and has proven to be solid and stable with good GPS. But like I said... the G2 GPS is flaky compared to other phones, I hope it sorts itself out with a complete refresh. That's what I would do.
Once you're up and running, turn on location and download GPS Status and toolbox. It has an option to download A-GPS data making your locks faster. Then watch as it picks up satellites (hopefully).

Roger that,
For me GPS Status and toolbox doesn't solve my problem (except if I'm connected to internet, the location is using A-GPS and doesn't show any sat). I think the problem is in using A-GPS beside GPS it self, if I'm not connected to internet the phone kinda refuse using GPS captors and wait for A-GPS... if I turn plane mode on then off the GPS reception start then stop and GPS Status and toolbox show many sat and stop too. I know this is weird but i was wandering is there a way to force not using A-GPS at all and see what happened. I think it's a solution for Chinese phone with MKT chipset maybe it's the same for LG. Sorry I'm not an expert so maybe I'm saying nonsense.

Yeah I don't think GPS status will solve your problem, that's why I suggested a full refresh. I never tried to force just GPS, but I would think disabling mobile data and wifi would do it, since it uses towers (and pull your sim).
I just picked up a refurb Sprint LG G2 LS980 from Freedompop. It came with 5.02 Lollipop installed. I have been trying to get the GPS to work reliably but it;s been a struggle. I find that I can only get it to work some of the time when my 3g radio is on. Doesn;t work for me on 4G/LTE or Airplane mode. When it does work, it works well enough. The GPS status app usually says I have anywhere from 8-22 satellites available but never connects.
Another odd condition, when the 3g radio is on, it never switches to 4g even when the GPS is not running. takes a reboot to fix it.
Anybody else have GPS issues like this and have any fixes? Not being able to use the 4G is not such a deal breaker for me since I usually uses offline GPS apps like CoPilot or Maprika. But I'd like this to be atleast somewhat functional or else I am going to have to return the phone. just weird that the GPS would be tied to the 3g Radio in anyway.
