[G2 Q&A, Help & Troubleshooting] chinyuk:
I agree with you, the problem is 2-fold, hardware and software/driver. I think your observation about power saving makes a lot of sense cause it is similar behavior I notice when I plug my car charger in (which is counter-intuitive since it is not relying on battery). I think it is a qualcomm driver behavior that does this or the chip is hard programmed to vary the power. I assume what it does is power amplification with the signal, i.e. if the antenna gets the signal in the first place.

As for the hardware, I agree with your assessment, I tried fixing #2 by pushing up the contact and didn't help. I fear I have the micro crack but I will honestly say this, even if the antenna was working 100%, I am not sure if this is a kick-ass antenna to begin with. Given that I mainly use this for my car rather than using it for a walk, I am really considering the re-radiating antenna route. I read a lot of people who fix their thing even with antenna foil but I honestly don't want to ruin the RF characteristics of the phone. Given there are probably 5 or 6 antenna in the phone (network, NFC, Wifi, BT, etc), putting any kind of extra metallic will offset reception. I know this cause I had the S3 and I bought a metallic case which they claim is tested, turn out it screw up my network connection and GPS connection as well as it won't connect after adding that shell.

I think it might be related to rooting, twpr and things like that (as mentioned before). I had excellent GPS performance for the first few days owning the device even without Wi-Fi or data enabled. Now after rooting and so on - it's terrible. And resetting a-gps data rather doesn't help much.

I had similar problem on my previous phone (Samsung i9103) - after factory reset GPS worked fine for a few days then bam! And the GPS is gone.

Verizon LG G2

I just want everyone know that I have the G2 and im on my 2nd replacement G2 and its having gps issues also i got my third replacement device coming in the mail on Tuesday. If this still continues I'll have them replace it with a note 3.I will not deal with poor manufacturing of devices. I came from droid DNA.Not once have i deal with gps issues this is a shame
[G2 Q&A, Help & Troubleshooting] hyperxguy:
ALL the phones are untouched (100% stock) ???
[G2 Q&A, Help & Troubleshooting] TheTanker23:
I'm completely unrooted stock and having horrible GPS issues. After the Verizon OTA update recently it's MUCH better at getting a lock quicker but it can't keep it locked at all. Before the OTA, It would take 10 minutes to lock in on my location in my house. Now it locks within a minute but if I'm driving anywhere it loses the location 15+ times every trip. When I stop at a stop light, the phone will think that I'm on the opposite side of the road and change directions (making me do a u-turn and continue the way I was originally heading). I'd love a fix for this because as of right now this phone has the most pathetic GPS I've seen.
[G2 Q&A, Help & Troubleshooting] MoNsTeReNeRgY22:
I don't think it is, at least from my experience. My original G2 and my current replacement were stock for about a week and I had problems then. I'm starting to get frustrated and will try a third replacement soon.

[G2 Q&A, Help & Troubleshooting] hyperxguy:
I understand your pain. We had a firmware issue with the 2013N7 and Google didn't fix it for a month (GPS would hang randomly).

I got similar issue (as yours) the moment I rooted & installed MalladusROM (was fine [MENTION=428455]Stock[/MENTION]). I just simply tried GPSTest, turned on internet

to allow it to update the AGPS and wait a couple of minutes outdoor to get a lock ---> everything has been fine since.

I normally turn off all data/wifi to test GPS, as it may get a location lock thru there.

Your unit may actually have a defective HW, otherwise I think it's mostly due to SW.

10:08 AM	Tyrus Jackson:	yes it is the best time of the year

10:08 AM	Gus:	Ditto

10:09 AM	Tyrus Jackson:	Say I got a verizon LGG2

10:09 AM	Gus:	What can I do for you today Tyrus?

10:09 AM	Gus:	:)

10:09 AM	Gus:	Ok

10:09 AM	Gus:	I see.

10:09 AM	Tyrus Jackson:	I'm Having GPS issues with the device not getting a lock

10:09 AM	Tyrus Jackson:	I've been threw 2 replacements already

10:10 AM	Gus:	Oh I see. Try powering the device off, give it 5 min or so and power it back on. See if it homes in then. Because GPS comes through carrier service and their towers, the phone itself does not have GPS built in.

10:12 AM	Tyrus Jackson:	wait!!!!!! what? Ok so there's not a GPS on the phone?

10:12 AM	Gus:	That's right,

10:12 AM	Gus:	In none of our phones

10:13 AM	Gus:	It uses the carrier service to get a GPS signal

10:13 AM	Gus:	Which comes from the towers.

10:13 AM	Tyrus Jackson:	so the phone dose not support turn by turn

10:15 AM	Tyrus Jackson:	Im in shock right now I would have never got the phone if it didn't support GPS

10:15 AM	Gus:	It will do this since the phone get a signal from the towers so it uses that to set GPS

10:15 AM	Gus:	But its not as exact as models with built in GPS

10:18 AM	Tyrus Jackson:	OK thanks I didnt know that I guess well have to get a diffrent device I need gps

10:19 AM	Tyrus Jackson:	so there not much I can do?

10:21 AM	Gus:	As for GPS nope.

10:22 AM	Tyrus Jackson:	OK thank you gus

10:22 AM	Tyrus Jackson:	I think i will talk to verizon about a diffrent device

10:23 AM	Gus:	Alright then, no problem at all, you are so very welcome. In any case, it has been a pleasure chatting with you today.

[G2 Q&A, Help & Troubleshooting] robogo1982:
All of you with GPS issues: do you use the Verizon version?
[G2 Q&A, Help & Troubleshooting] young0ne:
did you see what I posted
[G2 Q&A, Help & Troubleshooting] MoNsTeReNeRgY22:
Most of the people yes, have started to see other variants have issues though as well.
[G2 Q&A, Help & Troubleshooting] robogo1982:
Gus needs a) a salary decrease b) a new job c) a kick in the arse d) all of the above.

The G2, regardless of its variant, is equipped with a GPS and GLONASS receiver chip. Not like a software thing, but a physical piece of hardware. I don't care what kind of a network you're on, you cannot lock on to a GPS signal without a GPS receiver!
[G2 Q&A, Help & Troubleshooting] young0ne:
Im kinda shocked at the fact that I was told that this phone dont have a real gps.
[G2 Q&A, Help & Troubleshooting] robogo1982:
Really? Try this, then.

1. Put phone in airplane mode.

2. Enable GPS.

3. Try locking on to some satellites (GPS Test or GPS Toolbox from Play Store will do).

4. ???

If your phone achieves GPS lock WITHOUT mobile data or a network connection... what the hell then, man? :) :cowboy:
[G2 Q&A, Help & Troubleshooting] young0ne:
I did this for 10mins and still got nothing.
[G2 Q&A, Help & Troubleshooting] robogo1982:
Try rebooting the phone first. :)
[G2 Q&A, Help & Troubleshooting] young0ne:
that's the first thing I did.I just called LG and they said that they send it up to corp about the issue.
[G2 Q&A, Help & Troubleshooting] robogo1982:
Odd. Sometimes my phone acts exactly the same: "sees" a bucketload of satellites but won't connect. A simple reboot fixes everything, so that is why my bet is on software rather than hardware.

Here i was describing my problem with gps

http://xdaforums.com/showthread.php?t=2518020 especially with athletic programs like runtastic. I was writing then that i haven't problem with car navigation. I actually found out that i do but less obvious. It is international g2 802. Its like gps lose signal for a second and then connect again all the time.. I saw the photo with hardware fix with the cable. I didn't understand. Did you make to close the phone with the extra cable insight? Does it works better? I am thinking of doing it.. Thanks.

After the third replacement you have the option to move to an equal value phone under TEC and contract. 10 minutes ids a bit much even without agps. With agps then going to airplane, doesn't take long. Never tried straight airplane. Gonna try now.

Edit: Done test.

Fix with A-GPS, all 1 sec fix following.

Fix with GPS(Airplane mode[set before reboot and A-GPS cleared]), all 1-2 sec following.

[G2 Q&A, Help & Troubleshooting] masteril:
so the d802 international have gps problem too?or only verizon?
[G2 Q&A, Help & Troubleshooting] :
I have 802 international and have problem. But most users with problems have verizon. In any case even if you haven't problem, gps is bad. Galaxy s4 see more satellites and with beter signal for comparison.. I use runtastic for running and using the very old galaxy s2. Galaxy s2 needs 30 second to lock satellites when lg g2 locks in 2-3 seconds.

But lg g2 looses signal every many times. When s2 is very accurate. I run with both gps. S2 looses +- 10 m in 10km running , when lg g2 looses 270 m. It doesn't following my track in road.
[G2 Q&A, Help & Troubleshooting] Steamer86:

[G2 Q&A, Help & Troubleshooting] hyperxguy:
We have three Verizon G2s. None has had any issue with GPS on Stock.

I rooted mine and loaded Malladus and immediately had GPS issue. It was a quick and easy fix (get the GPS Test app and update AGPS).

I don't think it's a HW issue at all with the G2. Been navigating (with navigon) a few dozen times without missing a beat.
[G2 Q&A, Help & Troubleshooting] CruzerX_X:
I have this issue too. I guess it is the problem from software.

Sent from my LG-D802
[G2 Q&A, Help & Troubleshooting] :
I have done every software fix i have read here and elsewhere. Nothing.

I believe most users doesn't even understand that they have problems. Gps locks amazing fast. As someone write before it doesn't keep the signal constantly. As a result isn't vevy accurate. It is working for navigation in car but not very well. If you haven't anything else to compare you probably thing that all phone gps is like this..

If you use it for running it is obvious is very very bad.
[G2 Q&A, Help & Troubleshooting] hyperxguy:
I've had some GPS experience under my belt:

* Asus Transformer: GPS got very weak after Honeycomb.

* 2013 Nexus 7: more than one app using GPS and it would cease to exist randomly. It was a firmware problem which Google

didn't fix right away. So many users believed it was a HW issue then.

* Our 2012 Nexus 7s are perfect with GPS.

The G2 issue is just a minor hickup -for me-. We've been using GPS on Android devices for about two years. Our Tomtom & Garmin are collecting dust now.
[G2 Q&A, Help & Troubleshooting] :
I opened back of the phone and connected a cable like the one another one posted in a photo before. But i was able to close the phone without remove the cable from insight.

I test now in car, but i dont see improvement.. :(
[G2 Q&A, Help & Troubleshooting] young0ne:
Well I guess just talking to the right people I mean Ive had three replacements with in a week.So since the note 3 is the only phone that has a 800 snapdragon thats the only thing they could use that would be on the same level. between me ,you and the community I came up from a DROID DNA

so after my forth replacement with the DNA after a few months they put me the G2 then have this debacle with GPS 3 replacements I told to put me in a note 3. talk about I know how to talk LOL

GPS conclusion

I had some time this holiday, meet up with my cousin who has the same phone, same D803 (okay I am on Rogers, he is on Bell). In addition, I compare it to my brother's Optimus G, and the conclusion is clear:

Using AnroiTS inside a house, neither G2 will give any signal whatsoever. However, with my brother G, he was able to pick up around 6 to 7 satellite albeit weak but still able to get a location. I had them on for 5 minutes, still nothing. Looking at other who changed 3 phones and same issue, I think it is crystal clear to me it is a poor GPS antenna design which has led to this problem. And when you look at N5 user having similar issue, I think given the similar design, we can all conclude it is nothing we can truly do about this.

The funny thing is when speaking with my cousin who live in downtown area, (with taller buildings and what not) and I live in the more rural area with few high rises, he praise that the GPS is good and fast locking. In some case, it does lock very fast, I experienced it myself, but it is hit and miss. However, the accuracy of this GPS is very very poor mainly because the GPS signal is weak. So from 2 different user, we have 2 experience and I prove the phone are not one better than the other. Mind you, we are both technical people so it isn't like he doesn't know what he's talking about, he may not be a Android freak like myself and modify things and what not but I think why some people believe it is okay is because it sort of work marginally for them.

After that test, I shell out $100 for a GPS re-radiating device, I am really hoping this will solve the problem in the car at least which is where I use it most. When I get the unit, I will report back and let other know if it improve it (which I think it should) cause there is nothing defective about the s/w or h/w, just the antenna sucks.
[G2 Q&A, Help & Troubleshooting] :
If it is the antenna, isn't possible to change it?

To conclude that it is the antenna, someone must connect a better (probably with back cover of the phone off) and test the navigation. Any way to make a homemade test antenna?

I really love the phone except the gps..
[G2 Q&A, Help & Troubleshooting] MoNsTeReNeRgY22:
Just got my replacement, in the process of setting it up.

Will test and see if its any better and post back in a few days.
[G2 Q&A, Help & Troubleshooting] chinyuk:
Read this thread, someone has tried to do a antenna modification and it worked a lot better. I did some very quick test myself basically just temporarily attaching a long wire to one of the contact and it did boost the signal level as well, so we know antenna is one of the issue. I think software can only do so much to help like boosting amplification. But if the reception is weak, there isn't a whole lot you can do.
[G2 Q&A, Help & Troubleshooting] :
I have read. I also did this with the wire. Signal have a small improvement but problem doesn't. It has the same bad behavior as before. No improvement at all. So i am not sure if the biggest issue is the antenna.
[G2 Q&A, Help & Troubleshooting] young0ne:
I truly believe that the phone has a bad antenna design.I don't think after three Replacement I would still have a gps issue. When I got my note 3 replacement it took 5 secs top to lock. the g2 is a really good phone but I really don't trust the reliability now at least on the VZW verison.
[G2 Q&A, Help & Troubleshooting] kenkamm:
I have answered this question myself after doing some careful testing.

After I received my new Verizon G2 and found that the GPS worked flawlessly, I decided to test it for at least a few days after each software change to be sure that each change did not have any effect on the GPS functionality. I made only one change at a time so I would know what change caused an issue, if one were to arise.

I used the phone for several days, totally stock, and checked the GPS every single time I got in the car - which was between 2 and 10 times a day. I estimate I did about 13 hours of testing while the phone was completely stock, and the GPS always worked flawlessly. I used Google Maps and Waze as testbeds.

I rooted the phone using IORoot and did nothing else to it at that time. I tested the phone again for 3 days and found no issues with the GPS.

I installed TWRP only, and continued to use the phone, noticing no issues with GPS for the next 4 days.

I did the smaller nav bar mod, and used the phone for a few more days and confirmed that there were no issues with the GPS.

I did the status bar declutter mod, and this the last mod I have done to this phone to date. I continue to make it a point to use the GPS every day to be sure it's working properly. It still works great.

It's worth noting that I have not used any of the GPS apps that people are discussing in this thread. I have also not done a system reset, nor deleted dalvik/cache at any time on this phone.

My new G2 now has the same software configuration that the previous one did, and it works flawlessly, while the previous phone had very poor GPS functionality. Thus, it's clear to me that it's a hardware issue. Some G2s work great, some do not. Unfortunately it cost me a pretty penny to find this out for myself.

I'm going with software over hardware

My GPS never had a locking problem until a recent flash spree. I'm not sure as which flash it was, but it amazes me that even a factory reimage does not fix it. This issue has been present for over 1 week now. I have compared and edited the gpsconf file but still no luck. Can someone tell me how to mount and copy my newly crated conf file to system/ect? I keep getting a write error? How would I mount that volume or push the edited conf file via ES file explorer or ADB? Thanks in advance!

* I used this because CleanRom1.0 is stable and everything works perfectly in that build!
[G2 Q&A, Help & Troubleshooting] poundesville:
hi there,

If you've not done this. In ES explorer, you'll have to enable the root explorer function that will allow you to set R/W instead of the default R/O on the system folder.

Let us know if that Gpsconf file help you with locking issue - as i'm just like the other here, having the same issue trying to lock using GPS only

I had big problem with GPS, no fix in 30 min, 0 satelites detected etc, gps of course enabled. I realized that i didn't have gps icon in notification bar like always (when your phone is searching for fix you've got this notification "searching for signal" or similar). i used CWM to wipe data/factory reset (because it wont delete /sdcard like factory reset under settings menu). AND BAM gps works like a charm. fix in couple of seconds. I still don't know what was causing this problem.
