GPS Locking - T-Mobile LG G2x

Hi all, is it only me having difficulty locking on GPS? I tried stock, leaked gb, bionix and eagleblood but no lock. It shows 5 or more available sats but it won't lock.
Any help is appreciated.

No, definitely not just you. There's something definitely off about the GPS driver in this phone. If you use an app like GPS Status or GPS Test, you'll see that the signal-to-noise ratios are all lots higher than they should be; whether that has a direct effect on TTFF (time to first fix), I don't know, but it's certainly indicative that the interface isn't right. It's also clear that it's not using the AGPS the way it's supposed to; it should load the ephemeris data and give essentially a hot fix (<15 seconds) every time, but I only get a warm fix (75-120 seconds) if it's been long enough for the ephemeris data from the satellites to have expired (~4 hours) since the last time I used the GPS. It also happens that occasionally I won't get a fix at all, but generally rebooting allows it to get a fix quickly.
I don't know whether it will help or not, but you could try fiddling with some of the GPS system parameters via the hidden menu (dial 1809#*999# and find "GPS Test").
I'm hoping that this is one of the things that will be fixes when we get the Gingerbread/bug-fix update, but I don't have any basis for that hope.

Other than stock, which would lock super fast for me, I have had the best results with the Ultimate rom. The first lock took about 2-3 minutes but since then it has been fairly quick. Could just be dumb luck though lol.

With mine, the notification icon won't even show. Also, the 1809#*999# still gives me acore FC. Maybe someone else has this issue and can help.

You need to copy hiddenmenu.apk and two others to /system/app! It's there in one of the GPS fix threads on Development section! Search for it!

Thanks.
Looking...
Update: found the one you said but still i cant get the gps icon to come out.

Was talking about the FC when dialing 1809#*999#! That should be fixed once you put the apks in /system/app! From there you can run hiddenmenu -> GPS Test -> Start button and see if that brings up your GPS icon!

This may sound crazy, but download and give "GPS AIDS" (I know dumb name) from the market.
That app (even the free version of it) has helped every phone that I've ever had GPS issues with. The comments for that app speak for itself too.
Give it a try before buying to make sure that it is compatible with your phone first. Best of luck...

The setup always fails for me. The two files it needs to download don't download; the light is red for both and it says the file failed. I'm running CM7 so maybe that's the problem, but it just is not working at all.

[FIX][HOW-TO]Gingerbread 2.3.3 GPS Instant Lock

So I was wondering why some people with the new baseband where having issues getting instant locks.
Well it happen to me too and It couldn't get a lock. Really frustrating. Probably first thing everyone that likes to have a working GPS do is flash a different ROM. No more!
to fix this, what you need to do is the following:
Go to settings>applications>maps
Under maps
-Clear data
-Clear cache
-Uninstall updates
Open maps with an open sky first to download the required data, open GPS and BAM instant lock!
Try it and let me know if it works for you too

Gonna give this a try in the morning, will report back with results.
So we need an old version of google maps for it to work?
You don't have to have an older version, you can immediately update through market to the newest if you like.

Not trying to sound like a smarta$$, but if you're standing outside for a few minutes attempting this "fix", the GPS (unless disabled) is obtaining its lock in the background and is not dependent on the maps service. You could spend 10 minutes outside playing with your ding dong, then open maps and BAM! Instant lock!
Maybe somebody who isn't a noob like myself can confirm this, but I think you may have been too close to the trees to see the forest on this one.

If you install a AOSP ROM without Gapps you will notice that Navigation (gps) is not included until you either flash gapps or download "maps" from the market, since navigation is included with maps.
When I said I was getting instant locks I was actually referring to navigation and not to maps even though that I'm getting 6 meters of accuracy with maps.
Hope that helps

I see no real improvement. GPS still sucks in Gingerbread.
I had a bad GPS with my first G2X. Called tmo customer service and got a new one and now it locks on within 5-20 seconds. It's hardware, none of the software fixes worked for me.

I tried it and I got an instant lock indoors. We'll see how it hold up.
You need to open maps and let it download the data. Close gps open it, and you should great instant lock.

GPS isn't used unless an app enables it. Your phone isn't always searching for GPS lock in the background. It it activates when you open an app that uses it.

Op updated with more accurate instructions
Btw, this does works, been doing it with every ROM I flashed after I updated to the new baseband and in getting instant locks.

Thanks dude...that works for me....
No luck for me.
Interesting note: using GPS STATUS, I can get data from 8 satellites at a time without a fix/lock. The satellites however are all piloted on top of eachother. In otherwords, the app knows the birds are there bit doesn't know where they are.
If I check the birds with the hidden menu, same thing. The birds are there but zero azimuth angle and "false" ephimerus(?) data.
It seems like a simple software issue.....pull the data from the birds signals?

Rogers Gingerbread 2.3.3 Bug Report Thread

My fellow Canadians...
I have noticed a number of issues with the latest official firmware for the Rogers captivate. I think it would be a good idea to put them all in one place and try to start figuring out what common issues exist and perhaps we can address them all at once. Please state the issue, when it seems to happen, and what if any modifications you have made to your software setup. Maybe someone will notice a pattern or trend and we can get them resolved.
Thanks!

One major issue I have noticed is when updating apps through the 3.1.5 market. It seems to only happen when I am updating an app, not when I am installing a new app:
Sorry!
The application TwLauncher(process com.sec.android.app.twlauncher) has stopped unexpectedly. Please try again.
At which point I have to force close it.
Also, I have experienced random shut downs, I will click the power/screen lock button to unlock the phone, and it seems the phone has shut itself off. If you hold down the power button it boots normally.
Anyone else experiencing these issues?

Did you try a factory reset after you updated?
Voice for Swype
The voice command for Swype doesn't work.......
1. Speed dial no longer works. Says 'USSD code running' then closes and gives message 'unknown application'
2. GPS has stopped working completely.
As far as the launcher crashes, I don't use touchwiz. I do use Launcher Pro. It does seem to crash every so often. I've replaced all my widgets because I've read somewhere that this might help.
No random shutdowns here.
I talked to a samsung technical support rep and his captivate's swype voice input didn't work either.

GPS works perfectly on mine captivate 2.3.3 and I get better reception and locking time. But GPS will stop working if you flashed a custom Kernel on it! I know that because I tried it and GPS wasn't working when I had a custom Kernel, had to flash back the stock kernel.
Edit: I just tried Speed dial and it's working perfectly, I think there is something wrong on your phone.

Got the phone from Rogers with 2.1 then upgraded to 2.2 then to 2.3.3 (all done through Kies. GPS was ok but spotty on 2.1 and much better with Froyo but hoped Gingerbread would bring more improvement.
I've tested it since Rogers released 2.3.3 and on a few occasions I've even gone to the roof of my building on a clear day and waited for 45mins!! and nothing! Not lock then lose it but NOTHING! Speed dial I can live without but I actually use the GPS quite a bit.
Since upgrading I've done a factory reset 4 times and even sent it in for repair, which came back saying "upgraded SW and factory reset" which fixed nothing.
I've just rooted (just root nothing else) and I've tried to do use the gps code but I can't even get into that!!
What can I do at this point?

Yeah, with the 2.3.3 you can't access the gps setting by entering the code, because everything you enter the code *#*#3214789650#*#*, you'll get a message saying "Service mode has crashes blablaba...". The only that I found to bypass that was to go to market and install the app "Anycut" then launch it, select New Shortcut, Activity then choose Angry gps.
I'll look up what's the problem that causing you not to get a good gps signal.

Man I was going nuts trying that gps code. Googled and searched this forum and everything pointed to that code. Was ready to toss my phone off the roof!
Was reading these forums for the past couple weeks learning how to root/flash (just rooted today actually) to get gps working.
I'm guessing I might have to try flashing it again with the stock rom from this thread http://forum.xda-developers.com/showthread.php?t=979133 but gotta do some more reading before attempting it.

I use an app called GPS Status from the market. There, in the menu under 'tools', you can 'manage A-GPS state and wipe the location info the GPS has back to scratch. Then download the assistance data from the internet. This worked well for me and I do it from time to time to keep things current.

How long have you had the phone? The random shut downs is not a ROM issue. I am pretty sure it is a hardware problem. It was acknowledged by Samsung. There is even a list of effected builds. I am sure you could find the build numbers with a little search. I had this problem when I first got the phone last December but had Rogers replace it. If it is the same problem, I think you will notice that the sleep of death only occurs when the battery is like above 85% or somthing like that. It has been a while so I can't exactly remember.
I can't seem to get the firmware actually downloaded. I'm going through kies and it recognizes my phone, and recognizes that I need to upgrade, starts downloading the upgrade and at 12% it disconnects. I have two screen shots here that show what I am talking about.
Any ideas?

GPS not working after ICS upgrade.

I have a TF101 with dock, serial number C10 US, stock, not rooted. I did the OTA update to ICS two nights ago. I did not check GPS then. I just did a factory reset and after getting everything set up again I fired up Google Maps and tried to have it get my location. It could not. I installed GPS Test and it showed 0 satellites. I know that GPS was working on HC. Has anyone seen this issue? I think it is some configuration issue rather than weak GPS because I get 0 satellites so it seems like GPS is off. I checked that GPS was on in settings and it was and I toggled it on and off a few times. Wifi assist does work for location but GPS should work on its own. Anyone having this issue or know what I can do? Thanks in advance for your help.

Does that mean you did a factory reset and then restored all your apps and crap from HC?
Anyway, I just downloaded GPS Test and tried it. Works for me.
No I restored from the market and my Google account.
The backup system Google provides doesn't keep the apps individual settings. Those are lost the next time you restore them. The apps installed via Market is saved though and they get installed again.

The issue isn't really about settings of the apps. Most people use default settings anyway.
It's about the incompatibility of the app itself with ICS, which could be causing problems like rebooting, glitching sleep mode, preventing other apps from accessing GPS, and etc.
You should not be restoring every apps you had from honeycomb, especially if you are having problems.
After my update to ICS I tested the GPS with GPS test and it could see satellites biut didn't connect to them. It took several times clearing everything out and eventually it picked and locked on roughly 7-8 satellites and has been working since then.
But it was really slow initially and I didn't have any issues at all with HC.
You may want to edit your GPS.conf file. There are some GPS tweaks for android that I have found to be helpful. You can also download the faster fix app from the market and see if you have any luck.

Thanks randolphism for the helpful post, I will try.
I tested the GPS before I re-installed my apps and it still didn't work. I am not going to run without apps, the whole point of the device is to have apps. There is no evidence that this has anything to do with incompatible apps. The ICS OTA upgrade said it was converting apps to be compatible anyway.
Your advice may be relevant here, but again, your verbal abuse is unwarranted, if I were a mod you'd be on a vacation by now for foul language and disrespecting others. Officially blocking you now..

I would also suggest getting 'GPS Status' from the play store. I have found a few times where the GPS needs a kickstart, and GPS Status does it. Just open up GPS Status, and it will get your location, then go back to maps and it will nail it.

I used to do this too when I mixed up giving google apps permission to use GPS with enabling google ads. I simply refused to read that text about google apps and gps and assumed it was google ads lol. Wow did I feel stupid when I finally enabled GPS access for google apps and got that fast GPS again... I felt really stupid dumb :silly:
EDIT:
I've had issues with AGPS patch here in Sweden. When using the correct patch for this region it locks in about 1-2 seconds with an error in two whole kilometers and stays that way for 5-10 minutes after which it starts jumping between the correct location and a 1.5 kilometer error. AGPS patch is really obsolete and useless for me as GPS works flawlessly without it.
Premature celebration
seems I celebrated a bit prematurely, I got the gps working a bit when I patched the location fix however the main problem is still here. That being that the directions are give, my location is found however the actual route guidance just hangs. My location is shown, if I choose the turn by turn list all the correction instructions are give but for some reason the route guidance just hangs. I am now going to try reinstalling stock rom to see if it is a rom issue. Hope someone out there knows of a fix without having to flash back to stock I really like cm 10.1.2

GPS not working well

Anybody seem to be having problems with their XZ Premium GPS not working as they should be? Mine is intermittent, sometimes when it works, it works well. But the moment I took a wrong turn and quickly fired up my Google Map navigator, it have problems detecting where I'm at. The Map will show the route, but my location is all over the place. It would pause and stay in that spot for a while, then move me on a lake or off road. I tried "GPS status" app to pin point where I'm at. It doesn't always want to work.
It's getting really annoying, I want it to be reliable when I need it. Lucky I still have my Z3 as backup. So far, seems like the Z3 is the best Sony ever made.
Same problem here...It is hard to start GPS....it shows current position, it lose it. I have to fight for 10 minutes until its stable.
the same issue here. OK after reboot, but problem is back again a after
I had that problem once while downtown... the buildings in that area are all old and packed pretty closely together. It just did not want to update for the life of me. Rebooting it did not seem to help it at all. Especially using the walking directions... forget it. I didn't have time to fuss with a gps app to see if I just wasn't getting any sat connections, but if it happens again I will.
Wow, so it's a known common problem. I hope it's software related so it can be fix by updates. Now I have to open two programs to make sure it always working all the time. Run "GPS Status" app and then open Google Map. Cumbersome.
Dial *#*#7378423#*#*, service test, GPS, Purge Assistance Data
This worked for me!
My use of Purge Assistance Data seemed to help, but I've had a couple of episodes of the problem since then where it didn't help. However, in the past three days the problem has not appeared. I cannot determine what has changed; many apps have updated as usual, and in order to try to determine if this is a hardware problem I ran phone in Safe mode during which problem did not appear. Interestingly (or not) the problem has not occurred during subsequently use of the phone in normal mode. BTW, I'm running the July 1st security update (45.0.A.7.90); the August 1st version has not been offered to me yet by the Software Update).

Very nice. Seem to be working very well. Although I have not put it to full use yet since I'm working at home today. Let's see how it run when I go to work in the office tomorrow.
This won't help? - - https://forum.xda-developers.com/showthread.php?p=73337848
My XZ premium is 4 weeks old and had problems with the GPS since day one. The GPS was very unreliable taking me in the wrong direction and sometimes delays in giving instructions until after passing my turns. Using google Maps and high accuracy settings. Contacted Sony today and they have asked me to contact google first to make sure there is no software issues from their side before they can look at it. Meanwhile I will download a different navigation app and see if the same problem happens.
I did GPS location test but it seems everytime I attempt it the phone seems to take forever in finding anything so I give up normally after 10 mins.
If any one has found a solution to this problem please let me know (other than changing the phone of course)
My GPS problems went away with 45.0.A.7.120
You're not alone!! I always end up going wrong directions. Compass is very way off.
Sent from my G8142 using XDA-Developers Legacy app
+1 here. it's really frustrating as i use my GPS a lot.
I have the same issue. Second time I sent my phone to Sony. I will update the forum.
Was having this issue as well. Purned GPS Assistance data seemed to help. also did the battery trick. maybe sony should give us an update that will not allow gps to "turn off" when using apps that require it.
i searched on my phone some where on the hidden settings. The Destination was 30mins and about 20miles or so. Said the gps was only on for around 10. Cellular data was used too. This has to be a software issue. why it shuts off gps at times.
Is Galileo enabled as Sony's promise?

What is Galileo? never heard of this. Is it a GPS feature or improvement? Such a fancy name.

Galileo is a new GPS system developed by the EU, like GLONASS is the russian GPS and Beidou the chinese GPS.
And to answer the question, yes, our phone supports Galileo.

Yes, XZP supports Galileo. But it has not been enabled yet. :/
Had the same problem, gps not locking until I purged assistance data and rebooted the device, then it worked fine for about 48 hours until I had to repeat the process.
I completely solved this problem by uninstalling Google play services updates. This was a known issue for other phones some years ago.
Can anyone else confirm this solution?
