Over the weekend, my GPS (and GLONASS, incidentally) suddenly stopped working. I opened Google Maps to find my way home, and it could not find any satellites. Over the course of the past week, I ran various apps and tests, including a new ROM, to determine that this was not a software issue: the GPS is dead.
At least, it can't receive signals. The GPS unit hasn't failed as far the software is concerned; the system happily tries to grab a signal whenever you ask it to without any errors showing up in the logcat. I'm hoping that this means that something happened to the GPS antenna and that it can be repaired/replaced. The problem is that I can't seem to find any information on where I can find the GPS antenna or how I might fix it. The only information that I've found is this image from Anandtech showing the general location:

There's lots of information on how to repair an LG G2, but next to nothing in the G3. I'd really like to keep this phone running until the next generation of Nexus Phones are released, but I don't look forward to living without GPS for the next 4-5 months.
I've already replaced the screen on this phone (manufacturing defect that LG denied... bastards), so I'm not squeamish about opening it up, but it's also my daily driver, so I don't want to open it up more than necessary, hence the tons of research.
Any assistance would be appreciated!

I had similar issue turned out to be my FM transmitter in my car blocking GPS, realised when a Garmin satnav also failed to lock signal.

It's definitely not an interference issue; I get 0 signal (not just weak signal), and it happens even when I'm a hundred feet from cars or buildings outdoors. That's why I'm thinking that it's possibly an issue with the antenna that can be repaired (hopefully!), but I can't find documentation on precisely where the GPS antenna is to inspect it. My fear is that the issue is that the GPS hardware itself has failed, in which case the only real solution is to get a new phone.

So i picked up a Galaxy Nexus, was brand new (almost, package was opened but never used, checked the UPtime on the battery was only mins..) anyway. im and pretty certain it wasnt hacked or anything. it was just someone trying to sell their new free phone from a contract. model number i9250m
So i brought it to my GF's house, where i have never had any wifi issues, it would show normal good bars, connect and then get the IP.. internet would work fine, then all of a sudden, nothing.. turning Wifi on/off again, would sometimes allowe it to reset, but still, nothing more than 20 seconds... when i would use it in the bathroom (router is in the landlords on the other side of the wall.) it would work fine. No other devices in the house would give any issues over wifi...
SInce it was only 4.0.2 i though i would upgrade.. so i tried the nightly build cyanogen mod rom, cm-9-20120602-NIGHTLY-maguro-signed.zip still the same issue, even at my house, nothing, unless im 2 feet from the router.. 4-10 feet and a wall, no luck at all.
after some reasearch, they said change it to 5.0 ghz from 2.4, using one or the other didnt really change anything, (i think 5.0 didnt even work) i installed wifi analiser, here is what it is showing

with this reception, wifi only works from 4 feet. and is not that stable.. when it is connecting, it is super fast, but not consistant at all.
I have changed teh channel from 6 to 11, since wifi analizer said it was a better one..
I am using AWS (wind mobilicity) network. ANyone have any input or help?
thanks

i just replaced my new gnex for the very reason you stated. the phone also got very warm while charging and took grainy pictures.
so far the replacement is doing all 3 things much better.
i would suggest trying to get a replacement.
the funniest thing, i have 2 boxes (internet with built in router) and a seperate linksys, (used as a switch) i just disabled wif on the switch and everything works! that doesn really explain the problem at my g/fs house,
this was weird, because i was hacing the same issue with my Nexus S and an Ipad.. hopefully i dont have a faulty Wifi.. thanks for the help..
That's weird. You have super strong signal. I don't know why it isn't working. Haven't seen many posts about this issue.
I use Google maps almost everyday.. And my GPS either won't lock or it drops all the time.. I try rebooting my phone.. I tried changing roms.. Nothing helps.. I tried TW Roms and ASOP roms.. I tried in the city and in the country.. I even tried out of state.. And I get the same issue.. Right now I'm using pacman rom.. And on NB4 baseband.. Please help
First off, switch back to TW.
Odin the stock 4.4.2 and root it. Then try an alp like TopNT.
If that doesn't work could be the internal antennae in your phone, especially if you dropped it
Thanks.. I'll try that when I get home.
Also check the link in my sig for resetting the nvram. It's been known to work for many people.
Sent from my leanKernel 3.11 powered stock 4.4.2 (NF9) SM-N900T
I even tried replacing the device.. nope its HORRIBLE in the new device as well, my Note 1 locks so quickly, note 3 is crap.
This worked for me...
I've been frustrated by this too as I use my Note 3 in my car as a navigation device; I even have a charging cradle for it. Tried all sorts of apps (including TopNT) and suggested kludges for it to no avail. I searched YouTube one day for 'Note 3 GPS' and tried this. It has dramatically improved the GPS' performance:
http://www.youtube.com/watch?v=hC8jNb38gaY
The litmus test for me was how well it worked overseas. I regularly travel internationally and was frustrated by the phone's poor performance in a place like, say, Hong Kong. It took forever to obtain an initial position lock there. Now it locks relatively quickly as long as it has a clear shot at the GPS constellation and maintains the lock well enough to be useful while walking around there. At home it finds itself almost as quickly as my other device ( a Note 8.0) or my previous phones (an international S4 or an AT&T S2 Skyrocket). It used to be a little drifty in the car even after it had a solid lock; now it doesn't display that behavior either. It's worth a try. I hope that you find this useful!

After seeing this for the Optimus 4X (http://forum.xda-developers.com/optimus-4x-hd/general/guide-homemade-heatsink-easy-to-make-t2971385), I decided to try one for the G3.
I covered most of the back part (except the sd slots, camera, etc.), and although the heat still felt similar (when touching the power/vol. buttons), the games didn't lag/stutter as much (I'm assuming it's cause of thermal throttling).
However, one problem I'm experiencing is the GPS problem. The foil made it impossible to get a GPS lock (and I had to rip the foil out while I was driving and lost, thus no pics ). Furthermore, I tried Googling, but couldn't find information about where the GPS module is located on our phone.
Can someone help with:
(a) Trying it out and confirming that the heat sink really works and isn't just a placebo effect on my side,
(b) Locating the GPS module so we can hopefully work around it?
In regards to b, the GPS is on-die with the CPU, as seen here (In the most obvious place in my opinion, the site of the manufacturer xD)
https://www.qualcomm.com/products/snapdragon/processors/801
Qualcomm decided to put everything into one package so it's not spread throughout the phone and decreases overall size, so yes the GPS is with the CPU and almost everything else
If you watch any teardown video, you will see that the CPU/System die is exactly in the middle of the phone, right behind the lock/unlock and volume rocker. So keeping a nice square cut-out of the aluminum foil should let all the signals pass through, but then you won't have the heat being transferred from the CPU, only from around it so the CPU might still heat up :/
TL;DR: Not really much you can do because the GPS is on the CPU unfortunately :/
That graphic (from the Qualcomm site) is more an infographic than an actual layout of the cpu. Aside from that, it's only the GPS logic circuitry that's on the chip, not the GPS antenna. That graphic shows a camera on chip, too, but we all know the actual camera isn't located on the chip.
What matters for the OP is where the GPS antenna is located. That's shown in the image below, from the Anandtech web site: http://www.anandtech.com/show/8169/the-lg-g3-review/9

Hi there,
I purchased a PX6 for my 2009 Honda Civic last June and I’ve been having issues ever since I bought it.
The screen is generally heavily distorted, making the graphics look washed out and strangely warped. Occasionally, it will correct itself and look normal but it usually takes a bit of warming up/driving to correct it. Audio through CarPlay will frequently stop playing which only returns when I switch to the radio for an extended period of time. My back camera is also intermittent.
I’m starting to think it may be a power issue? I’ve also noticed certain lights in my car often don’t light up. The gearstick, AC buttons etc. I tested the battery I installed in my car, which came to 12.86 volts. Since updating the HMC a couple days back, I noticed it now displays the battery output in the menu bar. In the image attached, it’s showing 14 volts in the menu bar and when the screen randomly works correctly, the voltage is at around 13 volts. However, this is not conclusive evidence - as I’ve only just updated the software.
If anyone could please advise, I’d greatly appreciate your help.
Thanks,
Danny.

Can no one help me with this?
What happens if you turn the screen brightness down a little bit? Does adjusting brightness make the problem worse, or no change?

No changes at all. Exactly the same.
Have you contacted the seller or manufacturer? If it has never worked right, then I would be looking to replace. If it was purchased on Amazon, I'd suggest return or exchange. I know it's probably not the help you are looking for on the forum, sorry.
I recently bough a Redmi Note 12 4G from a carrier here in Colombia. The phone works pretty well but in this two last days has come to my attention a possible bug with the 2.4Ghz band. I use a pair of Vivo wireless earpods. but whenever i have the bluetooth activated, the WiFi signal seems to be obstructed or completely deactivated. When enter the WiFi list there is no a single network to choose, and what I have to do? deactivate Bluetooth and activate airplane mode, then deactivate the airplane mode and reactivate the wifi. Then the networks appears and i can connect to Wifi.
Im running MIUI 14.0.7 Global
I have the 4GB ram model with 3GB extra using the internal storage. I checked for 2.4ghz band interference but it happens anywhere i go, on my office or my house. Also try rebooting the phone multiple times but this problem is present. It not happens always btw, in this momento the phone is working well with both activated, but in the day it happens may be 4 o 5 times.
I have not touched the firmware of the phone, neither installed a rom or flash anything, its brand new and from factory.
I'm thinking of returning it if this problem continues.
Maybe you guys have an idea of what can cause this.
I guess it's the problem of the Bluetooth™ Standard because they share similar frequencies.
The closest thing you can probably do is to get an 5GHz router, turn off Wi-Fi all together or change your AP's channel to a less-crowded one
(TP-Link advises channel 1, 6 or 11 in case of interference, it might work ..temporarily)
I've had multiple Xiaomi phones and they all had this problem, let me know if you found better solution!
Something similar happens to me, when I try to use bluetooth with a keyboard and a mouse, both types of wifi (2.4Ghz and 5Ghz) download speeds drop a lot and it becomes unusable in my case since I need a good signal to be able to use a streaming service in the cloud.
Also thinking about apply the warranty (I bought it from a local seller with a 1-month warranty) and looking for another better device and clearly not Redmi or Xiaomi.
I will leave two images demonstrating what I have mentioned:
