I think there are 2 different problems

my device (D802) has a fast fix but losses the fix every 1-2 minutes .

1. hardware antenna problem . just touching the right upper corner of the device with my finger (without applying pressure) improves my GPS reception by 10db.

tried the electrical tape method , but no change .

2. when "GPS Test" in working at the foreground i almost never lose GPS fix . open waze - gps is lost every 1-2 min .

LG G2-D802 using CM10
[Verizon LG G2] Jaysusername:
Has anyone tried mapquest to see if the isssue persists? I believe waze uses google maps info as a base so it would suffer the same as google maps.

GPS fix

My guess is more issues with you're GPS hardware than just the antenna. I tried the connector fix on my VS980 bur I needed to replace the phone to get a fully working GPS. Certainly the antenna issue seems to be the most common but not the only h/w issue with this device.
[Verizon LG G2] chairthrower:
Hopefully a real solution.

A further update.

After my SIM card not helping, I went ahead and chatted again with Verizon. This agent decided that the problem was that I did not have Google Location Reporting turned on. I turned it on like an obedient little customer, and sure enough it got a fix pretty quickly. So she decided she fixed the issue.

Of course, a few runs and navigations proved that it was not in fact fixed. After reading up on this thread, I became focused on GPS accuracy as a metric for how good it was doing. My GPS accuracy never was better than 10 meters and was more usually in the 15-30 meter accuracy (when it didn't cut out completely, that is.)

So, I went back in this thread, and didn't just take off the back cover and fix the contact spring for the antenna on the back cover, but took the panel over the camera and back buttons. Behind that are 5 spring contacts, I presume for other antennas on the device. I did not put anything under the contacts, rather I very carefully (with a spudger) went ahead and pulled each of the contacts up a bit so they would make more positive contact with the plastic shield. I then put the shield back and screwed it fairly tightly back to the phone, and reassembled the case.

I then went outside and use the GPS Status app to test lock time and accuracy. Lock in under 10 seconds, and accuracy around 5-6 meters. I went for a run and it tracked pretty accurately--at least much more than it had before.

So it definitely seems like the contact springs under the plastic shield are relevant. I'm not sure if anyone has said that or tried it definitively. It's not hard to get under there--it's 5 silver colored screws and one black screw that is shorter, and you need a Philips 00 head (I have an iFixit toolkit which is great for stuff like this.)

I think the GPS may not be as good as other phones but this is more than acceptable now, if it holds up. I wish I could have taken pictures but you know, I would have been taking pictures with the phone I was taking apart so. . .
[Verizon LG G2] wilkster:
Very interesting and thanks for the post. I would be interested to see what signal levels you are now getting outside in the clear. This is what I have on my phone and it is quite a bit lower than other phones but not sure if it is just an LG G2 thing or what. If you capture any screenshots before the fix that would be helpful to everyone as well.
[Verizon LG G2] zubricks:
Any ideas?

Well, I was trying this fix, and bent the little gold piece too far..and it snapped.

Anyone have an idea as to what to lookup as far as replacing that, or is it built into the mainboard?
[Verizon LG G2] zubricks:
bump
[Verizon LG G2] wilkster:
If you are talking about the connectors on the attached, I believe they can be un-soldered and replaced. Due to their size it may be tricky and require a very small tip on the solder iron. Do you have access to equipment do that? You can probably make a small copper spring to replace the broken one.
[Verizon LG G2] zubricks:
My model is the verizon version, it is the copper spring I was trying to wedge some material under, and it snapped. Yeah might just need a very VERY tiny soldering tip. Wish me luck. I never thought have zero GPS would frustrate me so much
[Verizon LG G2] chairthrower:
My phone is barely getting a lock at all at this point. I called Verizon and they had me do a factory reset, which did not fix the problem, whereupon they authorized another warranty replacement. The rep sort of hinted if that doesn't fix it they might be willing to help me out somehow, but there were no details. He did offer me the opportunity to get a Droid Turbo on Edge but that would have been the end of unlimited data (although a 10GB Family Share plan would be more than twice what we ever have used.)

Hopefully the next phone works okay.

[Verizon LG G2] lattosimbaste:
I have been having issues getting and maintaining a good 3d fix for a while now. On a hunch I picked up a new internal top back cover (not the rear battery cover) and my gps performance is dramatically better. I lifted the protective tape from the original cover and sure enough, the foil antenna for gps was badly kinked at the corner. Not a smooth radius around the bend at all. Six bucks on eBay, definitely worth the five minutes it took to try. The contacts folks talk about bending immediately dimpled the tab connections to the antenna- I really don't think shimming or prying same is worth the risk, seems like a pretty well engineered connector from the two samples I examined.
[Verizon LG G2] ls.bastos:
Hello I'm from Brazil and this is my problem: The GPS connects while the 3G connection is off. Simply activate the data connection then GPS stops working immediately. Shutting off 3G, GPS back working very well. Any tips? My ROM is stock. The device is LG G2 D805. Thank you.

[Verizon LG G2] en11gma:
could someone please take a picture of the exact antenna spring that goes to the gps?

i seen Nexus 5 videos and talk about if you take back cover off and upper left corner.....etc....etc...

someone please take a picture and circle the gps antenna spring so we can all know if that is the area not making contact.

would be great to know all the antenna springs and connectors on the verizon vs980.

thanks

[Verizon LG G2] en11gma:
thanks for the pics.

i have been totally messing with the wrong spring connector.

i been messing with the one that goes to the back of the case.

will try the correct connectors on both lg g2's i have.

both are getting the same identical terrible signals.

cant even lock 1 gps inside. will go outside and try it before i take phones apart just to make sure.
[Verizon LG G2] wilkster:
Just be careful not to pry too hard, someone else reported they broke the spring clip off when bending it.

[Verizon LG G2] en11gma:
now i get this picture showing that the gps antenna connects to the actual case

http://xdaforums.com/showthread.php?t=2656187

does the spring connect to the case (that has no screws and just snaps on) or does the gps antenna connect to the part that has the 6 shiny screws and 1 black screw?

im getting different info on the location of the gps sensor.

sure would be nice if there was a picture showing the location of every antenna in this device but i would settle for just the gps antenna as both my phones are getting 0 signal using gps toolbox and location settings = device only and in airplane mode

i just want to try it this way for a bit to actual see gps sat data.
[Verizon LG G2] wilkster:
Here is a link to the VS980 service manual. The antennas are all described as well as lots of other good info. The VS model is a bit different than some of the other models which connect the gps to an antenna on the outer case. On the VS model the antenna is on the internal cover (the one with the six screws). The spring clips are under the internal cover.

Here is a version run through a PDF optimizer, it may work better for you.
[Verizon LG G2] en11gma:
thanks for the link to the pdf.

im on win 8.1 64bit and when i try to open it adobe reader crashes and says something about remote procedure call.

anyhow im glad you described that this "VS" model of phone has the antenna under the plate with the 7 screws.

i think the one with the 6 screws is the bottom plate.

the top plate has 6 shinny and 1 black i believe.

where exactly is the gps "spring" located?

i tried to open the pdf doc but couldnt

thanks
[Verizon LG G2] wilkster:
I modified my post to refer to a version run through a PDF optimizer.It is here. I don't use adobe reader so I don't have that issue. To get to the two GPS Antenna contacts you have to remove that small internal cover. They are located in the red circled area of the pictures I posted. You gently raise them up a bit then reattach the cover. Others have also put something non-conductive under them to make sure they make good contact.

Glonass satellites

Hi,

I use stock kit kat in my d805 G2. After doing the paper fix, I compared the AndroiTS GPS test side by side with my wife's S5 mini and noticed that about the same satellites were found by each phone (slight advantage to the S5).

Nonetheless one thing messes up the G2 connections ( I had already noted it before doing the mod): it doesn't connects to almost all russian satellites, while the S5 mini connects to them all. Even the ones with better signal level than the american ones aren't used by the G2 .

So this software glitch definitely prejudices the G2 locking capability.

Does anyone knows a workaround that allows or force the G2 to use all russian satellites found?

Thanks!
[Verizon LG G2] en11gma:
try this

put phone location setting to "Device Only" and then put in airplane mode and then power off phone and then back on.

now start up gps status toolbox or w/e app you want to use to check it out.

tell me how it goes.
[Verizon LG G2] kusjp82:
Wow! That really did the trick!

Do you know why does this happen?

Can I change the location setting back to "high precision" or this will bring the glonass connection problem back?

Thank you very much for you help!
[Verizon LG G2] en11gma:
just wanted to add some more specific info

dont forget i have 2 identical vs980's

both on 26a (1 rooted and 1 not rooted)

here is how the software (android or lg) works with the hardware.

1st if you go in airplane mode and disable all radios you will not be able to use apps like gps status toolbox or even google maps

google maps want you to have high accuracy mode on or it wont even work

put phone in airplane mode like i siad and try it.

i found out if you turn wifi on that it is still not enough

phone has to be in high accuracy mode and non airplane mode and also have a data connection

if you use gps status toolbox you can verify with the top left corner notification bar the gps satelite will have the symbol and an X with it. looks like a sat but it is not

and also it will go away after a few seconds.

disable airplane mode and enable wifi if you have to and the try google maps or gps status toolbox and the gps icon will change to where it has the signals coming out of it and it will not go away.

at this point you can put phone back into airplane mode and it will continue working as you will see.

there is NO way to do Device Only GPS

if you figure it out let me know

thanks and hoped i helped out

someone can prob fix this problem with a rooted phone.

if you do please let me know

gonna make a couple corrections

1st the gps sat notification showing the signals will eventually go away if phone is put in airplane mode with no radios working when being toggled to off while running the gps status toolbox app.

i opened up google maps with airplane mode off and wifi connected and i then saved the area where i live for offline google maps.

i then put phone in airplane mode (no radios working) and re-opened google maps and the gps sat notificiation showing signals did come on and this was in device only mode.

they got something really screwy going on here.

google maps (while in airplane mode) must do a check to see if there is data on the phone and if there is then it will let the hardware gps work.

if not it wants to connect to the net to get data.

just checked this with gps status toolbox also

working when google maps offline has downloaded some data (offline maps)

strange. very strange.

remember you heard it here first :)
[Verizon LG G2] bonestock:
Logged in to say I did the same thing and nudged up each spring under the shield and finally got GPS to lock. Prior to this I was not even able to get any sats to fix let alone let alone get a lock. I previously was getting 0/16 or 0/21 fix/sat every time I opened up GPS Status. I now get almost instant lock.

I first thought this was a software issue since the phone was running like **** overall on stock rom and I only noticed this issue after the GMaps update. Flashed CM11, downloaded many 'gps fix' type apps and fiddled with the gps.conf with no luck. I would suggest anyone else with this GPS issue try adjusting the spring contacts first.

I will no longer keep my phone in my back pocket. I am assuming I probably sat on it causing the cause to flex in and depress the GPS spring down.
[Verizon LG G2] al2fast:
So I've been having GPS issues, I had my phone apart 2 other times. Once to replace the headphone jack and another time I tried to boot into recovery and had a different recovery and it never went into recovery and just got stuck in a bootloop so I replaced the motherboard. I noticed some copper wires on that board with the buttons and just covered them with a small piece of electrical tape. My GPS has been really slow to lock if at all compared to my moto x. Got a new used board from ebay for $6 and when I was outside it locked in seconds where before it took minutes and was inaccurate. I had an incipio feather case on it all the time prior to ever cracking it open. No clue how it wore like it did. I also had an issue where the phone would freak out and think there were headphones/mic connected all the time and I would have to reboot the phone. That persisted after the usb/headphone board replacement but went away after the new motherboard. I also stopped using a case after I replaced the motherboard, that was about 3 months ago.

I'm telling you I didn't gouge this up when removing it where the wires are on the corner or to the right. A little further down to the right where the plastic pulls up is where I would pry with my plastic tool to pop it up. The replacement part also had a green tint to the camera lens cover as opposed to the purple tint on the one I had. I took the above pic with my G2 after I replaced it.

No GPS when no service?

Hi Everyone ~~

I "inheritted" a vs980 @ Xmas time, I'm still waiting for the Pageplus sim I ordered so I can USE it :(

So I got it rooted and stuck xdabbeb 230 stock ROM on it, have fiddled around with it gotten the knock-on to work (sort of) phone has signal, WiFi, everything checks out OK except for GPS. I've read the whole thread (and several related) but still unclear --

Do I need to have carrier service for GPS to work? I thought it just read the satellite signals seperate?

Please advise -- i've tried all the gps.conf, (flash zip) the topNTP app, etc fixes, opened the phone but wasn't sure what to fool with so I didn't, put it back together everything works, but still no GPS.

THANKS

VW
[Verizon LG G2] acejavelin:
Mobile data is required for aGPS to work, but you should be able to get some GPS signal without it... I don't think getting a SIM and working signal will fix it.

Did you flash Xdabbeb's 12B radio package, if its required for that ROM? Honestly the best "fix" I have found for GPS issues where nothing else works is revert to a JB/12B ROM, or a Lollipop AOSP ROM that uses 12B radios like Plain Andy.

Fair warning though, GPS is a known issue in some of these devices, it can be a hardware issue that no software can fix. I'm not saying that is the issue, but it is a possibility.
[Moto X General] StiM_AddiCt:
Wow what a wonderful evening. Decided to unlock my bootloader on my VZW Dev Edition tonight. The Motorola Unlock website keeps telling me that my device is ineligible. I start a live chat and they tell me based on IMEI that my device does not qualify. Then they look up my order (from motorola.com) and they find out that my device IS a dev edition. He then tells me that my software has been modified. WTF! I just got this thing and haven't even unlocked the bootloader! Fastboot reports that it's locked! I am then told to contact them tomorrow to talk to Tier 2 Support. I am beyond angry at this moment...

[Moto X General] weldawadyathink:
I would suggest just calming down and go thorough with the tech support. While it's quite frustrating, it was just a bug in the system. Being frustrated and angry will only make you mad, and will not achive anything. When you talk to support, if you are mad they are much less likely to help you. Your problem will be resolved, but likely there is nobody here who can help. Just talk to Motorola and it will be fixed. Hardware defects happen all the time. It is just a software bug.

If you do get an unlock code, you could post it here and maybe we can find the formula to get the codes for unlockable imeis. Just a stab in the dark, but worth a try.

[Moto X General] StiM_AddiCt:
Great lol. I was logged into my Gmail account when I tried to unlock the device.
[Moto X General] Cozume:
OK, well then I would tell Tech Level 2 to escalate it because it takes a few days for Tech Level 3 to call you back. You can try waiting a few days for the IMEI to make it into the unlock database, too, but I wouldn't wait more than 1 week from the ship date before pestering them to get on it.

Tech Level 2 just told me this exact thing I was surprised. She knew what she was talking about. She still escalated it to Level 3 for me however. Let's hope in a few days it will just be unlock able.

No its not linked to the same account. I bought mine on eBay and was able to unlock it. Just make sure that the account linked to your phone - the account shown where you have the quick toggles on the status bar is the one used when try to unlock it.

I had a few problems because I didn't realize that there were spaces when I pasted it into box. Just copy it into a word document and remove the spaces. Then paste into the section and the unlock request button will show at the very bottom of the page.

[LG G Flex] will0899:
It was available but not enabled. Maybe LG has plans for it, or a different variant will have it enabled.
[LG G Flex] aznrice2k4:
The dobly is actually system wide because instead of using LG audio effects, it uses the kernels dolby config. For those who want to really hear it, I recommend google play music. Open terminal and make sure its #

adb shell setprop tunnel.audiovideo.decode true

HOWEVER this is break the lg music app. Be warn

For me it's not an issue because I have all my music on play music.
