GPS fixes once then stops - LG Optimus 2x

Hy, i have a problem with my Lg Optimus 2x GPS.
With any GPS software, the GPS is fixing only once in a few seconds to 6-10 satelites then stops. The gps sign that appears near signal disappears also.
Normally the gps sign flashes when searching for signal then stays on when is functional
If i want to use the gps i have to restart the phone. And GPS works great but only for one or two times.
Anybody else is having this problem ?

It's working just fine here with the ROM/kernel in my sig.
What ROM are you using? Were you having trouble before using that ROM? (I'm just trying to figure out if it might be software related or not, it normally is).

The problem appeared when i upgraded the OS to 2.3.4. (original from LG)
I don't have custom Rom.
Kernel: 2.6.32.9
Compilation NR: GRJ22
Version : V20c

In my opinion you can try one of three different things:
You can try a factory reset, after backing up your apps (although I believe you need to have root access to backup your apps).
You can try downgrading to an older ROM again.
You can try flashing a decent (aka custom) ROM.

Installed cyanogen, Works great

[Q] GPS issues after wipe/flash new rom with wipe?

Hi there
I want to ask you about strange thing a saw after flashing my SGS with any other ROM than my stock PLUS GMS 2.1 Eclair JM2... It's a branded rom which i had when i bought phone in my shop. When i flash any other ROM (like Darky's or Doc's rom) GPS can't catch cold fix... Has problems with lock and sometimes it takes long time to see any satelites... When it get a fix, hot fix are ok later, but after about hour it has again problems with fix... Thats a little annoyng cause on branded ECLAIR GPS works great... I'm always making a wipe and format system before flash a new rom ald flashing roms with wipe option built in... Currently using Doc's v6.2 XXJPY 2.2.1 and same issues - problems with fix after no using gps... The worst is in the morning, after no using gps in more hours... Restarting GPS, restarting GPS status, and fighting with it and sometimes i cant catch fix gps in about 10 - 20 minutes or more... GPS isn't broken i thing if it's working on my stock branded rom... In LbsTestMode everything is seted up corrrectly... On flashed for test JPP radio (someone tells me that is best for GPS) where same problems... Is that normal after wipe that GPS needs few days to work properly? please help me anyone...
Having the same problem. Used pure JPY, GPS was blazing fast and acurate. Now with Doc 6.2 can't even lock to satelites.
if no one helps the only thing will be to flash stock JPY, and apply CWM and kernel with lagfix... But it may not helps... really no one knows whats going on with gps issues after wipe/flash?
Flash this via cwm and see if that fixes your GPS:

Sent from my GT-I9000 using XDA App
nope... didn't help... same problem...
Try this then:
http://db.tt/O5ompue
Flash via CWM then do another reboot.
If that fails, I give up
Sent from my GT-I9000 using XDA App
seems that it locks quite fast... 'll check again morning... but somethings strange. after few minutes of working gps is automaticly turning off? why? if im not moving and phone is not used and not moving it is normal?
i'm glad you're getting a quick lock with GPS now. As for your new problem, that is either application or settings related.

[Q] how to identify if gps is broken or if it's related to rom/kernel?

Hello! The gps used to work on my Ideos X6 but since a while back I can't get a fix. I thought it was because of flashing different roms and changing kernels that something wasn't compatible but now I've reverted back to stock with SUT and it still doesn't work. I've tried a bunch of gps fix-apps too but no luck. Do you think the gps is broken hardware wise?
try mokee it is beat for GPS
gps locks just in sec's

Try this, install fasterfix and choose a server for your region. In settings go to my location settings, disable "Automatic assisted gps" and "use wireless network" leaving only "use gps sattellites" option enabled. Now install GPS Test and go out into a region where you can see the sky clearly and fire up gps test and see if you get any sattelites. When the big yellow dot becomes green you have a lock, see if you can get any sats.

unfortunately my phone also faces gps problem but not your kind. Its just takes too long to get a f*** lock. Maps app shows direction correctly and turns when I turn, but the navigation app just wouldn't lock soon enough. So I guess the problem might be handset related, each phone behaving uniquely....... So I think its best if you flash stock and return your phone for a replacement before your warranty expires...
just my 2 cents,
whyzee
I had tried all those gps fix apps with no luck. I finally managed to get gps working by flashing an old stock rom with old kernel via SUT. I think the huawei versions' gps doesn't work with all kernels. As far as I can remember the gps stopped working after flashing one of the MIUI ICS roms, but I'm not sure. I'm going to try and root now and install Maclite, cause I'm almost sure I had gps working before with that rom.

MIUI ICS? x.x ICS theme or ICS rom? cuz AFAIK the only MIUI ICS here is zuk's abandoned MIUIv4 proj..
I have your issue as well after flashing to CK's Dark MIUI. but then I flashed edowar's libs-gps file and it's fine.. can be found somewhere in his CM7 thread I think.. now I get locks within 7-30s..

[Q] 3g, and wireless problem on my P990

Hi guys,
Because of the performance issues 10 days ago I decided to install custom rom so first I rooted my phone. After that I found the installing custom rom is diffucult (because I am noob) so decided not to do it.( i really didnt do anything except rooting).
2days ago because of performance issues again, I decided to reset my phone to factory settings by the option in the settings. During the prosses phone reseted itself and stayed at lg logo( light and lg logo came and went continiously). So i gave my phone to technical servise and they fixed it. (probably reinstalled the system).
But now I have problem with 3g and wireless. For example, wireless and 3g is switched off in settings but I still have internet connection( so stupid) and when i try to connect my wireless connection at home it fails until i open 3g. After opening 3g, it connects wireless and shows signal strength of wireless but after closing 3g, it doesnt show signal strength.
Does any of you experienced such problem and know the solution ???? Help me please.
Thanks a lot in advance.
Android Version: 2.3.4
Kernel: 2.6.32.9
baseband: 1035.21_20110622
LGE version: LGP990-V20a
(after factory reset, no update)
Hi, I never had this problem. My suggestion is to root the phone and try to flash a new rom. Search "Django Manouche 1.2 Renaissance", based on stock kernel v20q Gingerbread 2.3.4. I try it for a long time and i think is a very fast and stable rom. For install a rom you need tp flash a custom recovery. In XDA forum there are many posts that explain this. I hope to check out was helpful

[Q] GPS freezes, causes lockup, reboot, vibrates on CM10.0 or Stock with JVT BASEBAND

Each time the GPS kicks in (either through browsing Google Maps or via the Camera's photo-tagging) the phone freezes completely and if I attempt to go back, the vibration motor kicks in and does not stop.
After a few seconds, the phone reboots itself.
I have tried this with several basebands and it happens both on stock 2.3.6 and on Gingerbread 10.0 and 10.1 with the JVT baseband.
This is the international (European), unbranded GSM version of the Galaxy S GT-I9000.
The only times when I do not get this problem is when I install a Baseband/Modem that does not work and therefore none of the radios function.
I am not sure if this is a radio issue as I have tried flashing a ton of different radios/modems/basebands both through Odin and via CWM and I cannot get the GPS to work at all.
Coarse location (i.e. cell-tower-based) works fine.
Hope anyone out there can help?
Thanks!

Problem with GPS in non stock ROMS

Hi togehter,
I bought a Galaxy S3 Mini i8190N from an offer here in germany last month, the phone has a sim net lock. First of all I am experienced with flashing custom roms. But for my issue I never found any available topic.
I had no problem rooting the device and I can also install and run several custom roms, but for non stock roms I never see any satellites in view (GPS Test, GPS status & etc.) Everything else runs fine, WLAN, BT etc.
I tried to change the ntp pool settings to germany / europe, but this doesn't help (Faster fix, also manually system/etc/gps.conf).
In stock roms / custom stock roms GPS is working fine and I get a fast fix, I see a lot of satellites.
What I also tried:
Going back to orignal stock rom. Made a hard factory reset.
I tried flashing with Odin and also with TWRP v2.7.1.0 20140612, but this also does not fix the problem
Before installing non stock rom, I made a factory reset and deleted cache/system/davlik cache, but gps is never working. The symbol is appearing, if a app wants to access GPS and I also changed gps settings to high resolution.
Does anybody else have same problems?
Roms I tested Carbon, Omni, Slimrom, Cyanogenmod (MacLaw), I also tried Omnirom from goldenguy
I can provide more informations, if someone has an idea about it.

Update:
Hi together,
I again started to understand why GPS works fine in roms like R-Mod3 (Cutstom STOCK) and does not work for all kitkat roms >=4.4.2.
Enclosed you find the debug logs of google maps and gps test for omni-4.4.4-20140801-golden-HOMEMADE . In both apps I get errors in debugging. Can someone help me understand the problem here?
I guess it's a driver issue for android versions higher than stock rom.
Have you tried CM10.1?
