I have also noticed that it has trouble figuring out which way I am heading. Lets say my google maps has me going north, my arrow might be going north but it pointed West. Seems all screwed up.

I had the same issue. Downloaded GPS status from the play store, ran it, and now I get lock in seconds.
[G2 Q&A, Help & Troubleshooting] MoNsTeReNeRgY22:
For me, it's not necessarily a lock issue, it's that I will have a lock and then it will tell me gps signal lost.
[G2 Q&A, Help & Troubleshooting] cyberr8der:
Since this seems mostly to be on the Verizon model has anyone compared the GPS.conf file with another to see the differences? Maybe this can be an easy fix.
[G2 Q&A, Help & Troubleshooting] afmracer6:
I called Verizon today about my GPS. They said its a known issue with Verizon lg g2. They said the first batch may have been defective. They are sending me a new one.
[G2 Q&A, Help & Troubleshooting] g2x_pig:
I've experienced the same issue with my T-mobile G2. Only way to get a solid GPS lock is to turn on google location services. Even then the lock is "fuzzy" and accuracy is 30-80 feet.
[G2 Q&A, Help & Troubleshooting] MoNsTeReNeRgY22:
Mhmm thats interesting. Keep us updated.

Also curious, how long have you had your G2?
[G2 Q&A, Help & Troubleshooting] afmracer6:
I got it a couple of days after launch. So a month or so. I'll let you know if the new one is better.

Hey Guys

I was suffering with same GPS signal problem like others here.

I cant say that i already out of the prolems but I noticed a thing that really makes difference and i want to share..

First of all i have to tell, my phone didnt find any satelites indoor/outdoor no matters

I put the following line to my gps config file:

ACCURACY_THRES=80

with this setting i was able to see 4 gps satelites inside the room, then i went out, and locked in another 3. The signal strength still was weak and probably not enough for navigation, but more than nothing

I also tried to set values: 50 and 5000, but they was not work so good like 80.

I'm really sad because of this problem. I like this phone so much and this gps problem is like nettle in ass..

Turn on your wifi and leave it on. Always.
[G2 Q&A, Help & Troubleshooting] iRandoMi:
I also have been unable to get GPS working on my vs980. Regardless of what settings I change within the gps.conf file or what ROM I'm using, I receive absolutely 0 GPS signal when checking via GPS Test.

Worth noting, I'm unsure exactly when it stopped working as I've also gone through countless ROMS, however, since I've attempted to find a solution, I've tried PA (Currently 3/5 but have been using it for a while), Cyanogen M4, OSE, Pac Man and Carbon. I've downloaded multiple gps.conf files and I've attempted to edit the settings myself via Text Editor and/or FasterGPS.

Any suggestions? :eek:
[G2 Q&A, Help & Troubleshooting] iRandoMi:
I just wanted to follow up to my initial post that I've been able to resolve the issue. For nearly 2 weeks I was unable to get GPS working with any KitKat ROM even though I it was initially working when ROMs switched over to KK.

My only fix was to go from PA 4.1 beta (3/5) > Malladus 4.2.2 > Clean Install of PA 4.1 (3/5). As soon as I switched over to Jelly Bean, GPS Test would register roughly 20 GPS satellites and it seems to have stuck when switching back to KK again. Hopefully this helps anyone else experiencing these issues!
[G2 Q&A, Help & Troubleshooting] charlesip:
I can confirm that by applying light pressure on top right corner from the back cover will immediately boost my GPS signal strength. This correlates with the theory that the GPS antenna contacts on the D802 can be lose inside the back cover. It used to take forever to get a fix, but by applying pressure on that corner, It can now get a fix in a reasonable time. Releasing the pressure will see an immediate signal drop.

Does anyone have a permanent fix like they have done on the Nexus 5?
[G2 Q&A, Help & Troubleshooting] trojjanhorse:
Hi XDA, thanks to this thread, I was finally able to fix my G2 from Bell.

A little backstory: I took the phone to Bell and they simply flashed stock firmware and gave it back to me a week later. Of course this did not help as I've tried this myself. *Honestly, do they have monkeys working there?*

So I opened the back cover, raised the pins, that didn't help... perhaps the pins are not very strong and bend back down very easily.

Then I attached a wire to the pins and tested, surprisingly got really good GPS signal.

Next, I peeled off the connector from the cover and put some double sided tape (very thin) to lift the connector a bit and closed the cover. Now i'm getting same (if not better) results as my Nexus 5.

Below are pictures of a)connector and b)GPS Test results indoors.

Hopefully this helps. A thanks would be nice if it does indeed help you :)
[G2 Q&A, Help & Troubleshooting] jadedrk:
I already did the same thing and it really worked, i was looking to help someone but u already did. I did it by just pulling antenna connectors with sharp nail. Now its working inside my room with 3meters accuracy. Its on top floor but concrete walls n roof.
[G2 Q&A, Help & Troubleshooting] natureburger:
No doubt. Most users have never relied on a real GPS app and so they think that the Google Maps is accurate when it is just using Data and Wireless to triangulate with low accuracy. Out of data or wireless, this phone locates worse than any phone I have had.

Install the free GPS Status and this will rely on GPS only to get a location fix and then you will know how good/bad your location fix is.

Yes. I have confirmed that they have monkeys (or worse!) working there.

In Canada, never call the 1-888-542-2623 support number on the LG Canada Website. You will get a call-center and they will deny that there are any problems with the operation of your phone. LG customer service is among the worst I have experienced.

Go to your carrier.
[G2 Q&A, Help & Troubleshooting] stillwaiting255:
Replacing the file with the stock version for vs980, which I attached ( I had to rename to post but just change it back to gps.conf ). Also make sure that you have given Google apps location permissions. I use to have lots of problems with GPS until I did this. Make sure you reboot after you make changes.

I get 10 satellites in view. But it ignores most of the glonass satellites even though they are of the same, or even better, strength as the US ones.

Anyone else find this system preference for US instead of using the full advantages of glonass?
[G2 Q&A, Help & Troubleshooting] robogo1982:
Either give it some more time to lock onto Glonass satellites, or clear AGPS and start all over.

Sadly, this trick did not work on the Z (which is why I sold it), but it works on the G2. Either that, or run GNSS test from service menu.
[G2 Q&A, Help & Troubleshooting] natureburger:
Today while driving it took 45 minutes to lock on. And when it finally did, all the USGPS satellites were being used but only 2 of the 7 Glonass satellites. My BlackBerry Torch GPS is waaaaay faster to lock and keeps the lock better. Something is seriously wrong with the software when 22 satellites are accessible on my horizon and it takes 45 minutes to lock. I would love to see the GPS code and see where things are going wrong.
[G2 Q&A, Help & Troubleshooting] jadedrk:
finally fixed the gps

Hi guyz, its a long story short, i had following issues.

1: weak gps signal

2: gps losing fix

3: gps always searching never got a fix

After pressing top right corner it boosted gps signals for a while.

I did open the back cover and pulled gps antenna connectors a little bit and #1 and #2 were fixed, but i was still having #3 issue.

Then i tried slapping phone on my hand and it did worked for a while, so it seemed like a hardware issue to me and it really was bad soldering. Bcoz after much slapping it never showed any sattelites. I thought i permanently broked the gps.

Solution for no 3: i opened the back cover as well as antenna cover on top and noticed there are two resistors connected to each leg of gps antenna connector. On my phone of them was missing. Bcoz i slapped too much and it was loosely soldered. I tried to find the missing one but i didn't. Then i just soldered the missing one and now all gps problems are gone. I get first fix in 12 seconds without Agps. i m getting very strong signals even indoors.

If someone post a picture of g2 mainboard i can highlight the defected resistors.

Cheers
[G2 Q&A, Help & Troubleshooting] Maestroramas:
Is the picture of the back cover or of the front part? I opened the phone but I cannot find the 2 resistors. Can you upload a better picture? :)
[G2 Q&A, Help & Troubleshooting] jadedrk:
Here we go, i have marked the screws that you should unscrew and remove the cover and you will be able to see the resistors.

TIP: if you can(most probably u will) see the resistor as in picture, try touching a copper cable with resistor to see if you get better signals then for sure its the same problem.

in my case when i touched the cable to gps antenna connector one by one i didnt got any signal, when i touched cable to the point where resistor is connected i got gps fix within 2 seconds with very strong gps signals.

in my case there was no resistor there at all so i shorted both points by soldering. and if you have resistor there try re-soldering it first.

Be careful when soldering, make sure phone is turned off before touching the soldering iron and also make an earth connection with soldering iron if possible.

do at your own risk.
[G2 Q&A, Help & Troubleshooting] Maestroramas:
Sorry but it's not so clear what to do with connectors: what I have to check and then repair in case? Is there any video describing this?

I only tried to fix with the paper: in a first time everything seemed to be solved, but after some hour the problem came back again. I want to try your solution.

Anyway, has anyone sent the phone back to warranty? How does it work their fix?

Thanks :)
[G2 Q&A, Help & Troubleshooting] Ainvar:
I have the VZW LG G2 model and I ended up taking off the back case. On the side that has the SIM card slot is where our GPS sensor is and is also the side of the battery cover that the GPS antennae is located.I fixed the issue by sliding a piece of cut electrical tape that I folded sticky sides together and placed it in the spring/hinge side of the GPS connector that is on the phone itself. I also applied a small cut piece of electrical tape underneath the antennae connector plate on the battery cover.

So far I am getting GPS lock 100% of the time that I have tried it yesterday and today within 3-7 seconds of opening up Waze, Google Maps, !Weather, GPS Status, Dash, and anything else that needs the GPS sensor. I have also noticed better battery life due to the phone not constantly looking for a GPS signal while indoors or outdoors when I am using a GPS enabled app.

Here is a picture from another XDA thread by JTNiggle that shows the insides of the VZW LG G2.

First picture shows the battery cover and you can see the small square copper connector for the GPS attennae.

Second picture shows on the right side of the phone above the battery the little springy copper connector for the GPS sensor on the phone.

These are the two areas I used very tiny pieces of electrical tape on to make a solid connection.
[G2 Q&A, Help & Troubleshooting] natureburger:
There seems to be a lot of confusion about where the actual antenna connections are for the GPS. Does anyone know for 100%?
[G2 Q&A, Help & Troubleshooting] chinyuk:
My understanding is that if you are looking at the screen, it is on the upper right hand corner. There is 2 small foot print on the very edge of the phone.

Quite honestly the GPS is still a bit of a hit and miss for me all said and done. I was one of those who looked into the issue. What I ultimately did was bought another back cover populated with antenna from ebay. Note that not all back cover comes with the antenna and the signal is stronger but still far from perfect.

It could be also because I was running Mahdi KitKat (prior to official 4.4.2 from LG) and it is slightly better in determining signals and it is passable at best.

However, as the ROM mature, I think one of the initial problem I had that it never get any GPS signal seemed to be gone, which was a pain in the neck cause you know at the very least, even if you can't get a lock, running any GPS app should give you some signal.

My solution at the end of the day (at least for driving) is got a re-radiating antenna in my car. With that in place, the thing works like a charm with great accuracy and using AndroiTS, I easily hit 40~50 for some of the satellite whereas in the best case scenario, I hit 30 on one or two satellite. There is no question the GPS is weak on this unit at least for some of the faulty unit.

I know my uncle got this phone more recently and his was strong as anything. I mean, within the house and 2m away from the window, I get 0 satellite yet he can get a lock. So to me, there is definitely some faulty hardware issue here.

Just wanted to share with you the info. Quite honestly, I do use the GPS, but not to the extent where it is to to max.

On another note, I just came back from Japan and I used the GPS quite extensive without any assistance like in my car and I find it to be passable. I mean, there are times it does take longer to realize where I was but other time it wasn't too bad. I think the other thing about Google Map is that it uses wifi signal to get approx location so even underground, I was able to get whereabouts of where I am under a 3 metro station interchange. I was pretty impressed with that.

So to me, despite this unit being far from perfect, with the maturity of the Mahdi ROM and a new back cover, it seemed to now become a passable unit with not that great accuracy of course.

Which GPS radiator did you get?
[G2 Q&A, Help & Troubleshooting] chinyuk:
http://www.amazon.com/SBG-190-Re-ra...d=1397190191&sr=8-1&keywords=gps+re-radiating

They work pretty well. Just make sure the reception antenna is outside of your car, I put it near my shark fin antenna on the roof of the car and the re-radiating antenna inside of the car. Otherwise, putting them too close will have a loop-back issue.

Just used it today, 16 GPS locked and 3m accuracy. Works like a charm. The only downside to it is that it only boost US satellite and not Russia since the frequency they used are different. But even if you get good signal on 10~12 satellite, the accuracy is good enough.

Repair shop is replacing my main-board. Waiting with great anticipation.
[G2 Q&A, Help & Troubleshooting] Maxxy13:
I see you're also on Bell. How did you get them to replace the motherboard? For me they've just reinstalled the software which naturally didn't help at all.
[G2 Q&A, Help & Troubleshooting] natureburger:
1st - well,we will see if this works and is the solution.

2nd - I sent them a 'very disappointing GPS performance' complaint message on facebook LG Canada.

3rd - It is bad performance. I am now using my backup Blackberry Torch, circa November 2010, and it has GPS, without assistance, that works waaa...aaay ('way' with 1,000 'a's) better. (and the Blackberry Torch does not even use Glonass which should have given the G2 a big advantage).

4th - I was impressed with their attentiveness to the issue, especially after getting the runaround from their phone help line which is obviously a very unqualified call-in shop contracted to give lip-service in Toronto.

Like I said, we will see if this works. Waiting patiently to get my phone back.

As per my other post on another thread, I found this explanation of how the processor chooses between GLONASS and US-GPS:

http://www.qualcomm.com/media/blog/2011/12/15/gps-and-glonass-dual-core-location-your-phone

They sell the Snapdraon as enabling GPS with (a) Battery Life (b) Reliability "GLONASS makes sure you can use location-based services in more places by accessing more satellites." (c) Increased Accuracy "This allows your location to be pinpointed to as close as 2 meters."

Then, main Snapdragon CPU is big part of the GPS problem/solution and maybe there was bad CPU/Mainboad units that made it into production units.

Again, waiting patiently to get my phone back.
[G2 Q&A, Help & Troubleshooting] robogo1982:
The GPS/GLONASS system management actually makes a lot of sense.
[G2 Q&A, Help & Troubleshooting] ls5454ss:
Hey everyone. Just be careful with this fix. I guess my friend put too thick of a piece of tape, and it moved the antenna piece when the cover was snapped back, and bent the GPS pin on the board on a friends phone. Trying to unbent, it broke off. He had to put a dab of solder on the circuit board and THEN do the tape fix. It works now...GPS is able to lock in relatively quickly (10s or so...)

Another thing to point out - on your Bell phone, it looks like there are TWO GPS connectors there. On the VZ variant, there is only ONE (the 2nd space in the antenna / circuit board is BLANK. This may also have something to do with VZ's poor signal over other carriers.

Thanks to the OP for finding this.
[G2 Q&A, Help & Troubleshooting] natureburger:
The phone is back from the shop. They replaced the mainboard. The GPS now works 1,000 % better than before.

=== Before ===

First lock with no aiding data, only 1/2 sky available: 245 seconds.

Second lock: 10 - 14 seconds.

Fix while in office 2 metres from big window: never

=== After ===

First lock with no aiding data, only 1/2 sky available: 74 seconds.

Second lock: 1.4 seconds.

Fix while in office 2 metres from big window: 2.4 seconds to fix

Bada Boom Bada Bing!

Glonass is showing, but after a good fix, it switches to just GPS. Fine with me, because it at least show 2 or 3 GLONASS while getting the fix and a short time thereafter.

So, if your GPS sucks, maybe you should try getting it repaired.

edit: of course, we will have to see what it does on a cloudy day or while driving. But still, the way the GPS found and fixed the location was waaay faster than before and I never got a fix at home inside 2 meters from the window before - never!
[G2 Q&A, Help & Troubleshooting] dfryer1193:
I was having issues both getting a GPS lock, as well as maintaining one while on the move. After trying many (all) of the software fixes in this thread, I opted to try inserting something under the GPS pins. After sealing the phone back up, all I can say is WOW does it make a huge difference. Went from 5-10 minutes to get a lock to maybe a second or two (and it's cloudy today). I intend to make some sort of guide on how to do this soon, for anyone having trouble.

For reference, I am on a Verizon LG G2 (the VS980).
[G2 Q&A, Help & Troubleshooting] natureburger:
After a few days I can say it is officially fixed. Replacing the mainboard (LG hardware warranty) fixed all GPS problems and it gets a fix in record time now.

GPS is getting fix indoors, outdoors, cloudy, raining, in record time.

Very good performance now.
[G2 Q&A, Help & Troubleshooting] Maxxy13:
Glad to hear the issue is fixed for you. So you have approached LG Canada, not Bell for this repair, right?

Considering that I'm in exactly the same situation - LG G2 on Bell, bad GPS signal, how would you suggest me to deal with it? Call LG Canada? Post on the Facebook page?
[G2 Q&A, Help & Troubleshooting] natureburger:
Do not call them. The customer service staff are just a call centre and know nothing about phones or gps technology.

Do post a message to them on Facebook. What you need to tell them is that the GPS is acting up and it no longer works. It will help if you tell them that 'you were very hopeful with the superior G2, but GPS is so bad as to make the phone unusable for driving, navigating, map locations, etc.'

Try that. They then messaged me on Facebook to get my serial number and IMEI and full contact information. An LG rep contacted me with a full repair authorization and a free Purolator delivery to the repair centre.

I also emphasized to the repair centre how bad it was.

Then ... less than 10 days I got it back by courier fixed.

Make sure you wipe the system and restore to factory if you rooted.

Good luck! Push this all the way and you will get their attention and have a fixed phone.

Mine is still working perfectly, clearly they fixed it when the replaced the main board.

[G2 Q&A, Help & Troubleshooting] factory81:
The proof is in the pudding, or something like that. I noticed the GPS performance today while driving. It struck me as a bit odd that I would lose signal while driving down the road in my car with the phone in my hand. But it did. In fact, I kind of had to baby the phone and keep it in clear line of sight to the sky on my dashboard for it to work well. My previous phone was nothing like that at all. Today was my first experience with the LG G2 GPS. I just switched over the weekend.

I have a Galaxy Nexus (CDMA) and a LG G2 VS980. I installed the GPS Status app on both phones, and the Galaxy Nexus gets a full lock on with multiple satellites in seconds. The LG G2 just hangs out looking for gps location. I have google location services on, and the LG G2 even allows me to try and set the accuracy....of the gps, and it is set to high accuracy.

If I go play around with it by the window in my apartment, I can get it to pickup one satellite maybe.

I reset the AGPS data, downloaded new data, I used FasterGPS as well. No improvement with either apps.

Unsurprisingly, the community at XDA has found ways to disassemble their phones and try and improve signal there, but is there any other options for those not looking to try and bastardize their beautiful phone? I see other people having verrrrrrrrrrrry mixed results with replacements, and other roms.

I mean, are people confident in saying this is definitely not a software issue? Or are we unsure? Or is this more of a hardware issue as some people are suggesting? Or are we just throwing everything at the wall and seeing what sticks?

I didn't read all the pages, although I am glad there is a good amount of discussion on this. We are definitely not alone in this issue. The GPS performance as of right now could only be considered paltry.
[G2 Q&A, Help & Troubleshooting] natureburger:
Yes, you need to read my last few posts. Get it fixed. It is the hardware. Start with LG as per above posts. If that fails return it as broken/defective unit via carrier. Good luck and don't settle until they replace the defective hardware. Then you will be amazed how good it really works.
[G2 Q&A, Help & Troubleshooting] factory81:
I bought my phone used on swappa. I bet Verizon is not going to help me here. So I think I only have LG as an option.
[G2 Q&A, Help & Troubleshooting] factory81:
Also, did you do a factory reset before you mailed it in? Did you unroot the phone? My phone is just rooted + wifi hotspot mod. I have everything setup the way I like it. I want to backup the install, and restore this in the event that they wipe it. What is good for that?
[G2 Q&A, Help & Troubleshooting] natureburger:
I did a factory restore using the LG Mobile Support Tool. Also, I did a factory reset and removed my SIM card using a paperclip.

You have a custom recovery? No, then get TWRP or Philz ( I only know TWRP) and then do a full backup (Nandroid backup).

But if all you have is root, then you might just want to do a return to stock and factory reset and then root it and do the mod again later.

In the forum there is instructions for factory reset.

BTW - my root flag was showing and they never said anything about it. But it is safer if you un-root first.
