I had a problem with Google Maps V7+ on LG G2 4.4.2.

I could not get a fix on google maps even though GPS Fix showed plenty of satellites.

Read to much info but eventually found Google Maps V6.14.4 for non root install would work even with Google maps installed.

And now I get a fix within 10 seconds or faster. Love it. The GPS is fine it just some conflict as Waze was bad to.

Fixed!

I have tried several suggested methods to fix the GPS locking issue but to no avail. I decided to try something different: solder an antenna directly to the board. I decided to use wire for the antenna. Not sure what gauge I used but it seems that that bigger the wire, the better the connection although you want to make sure that its not too thick. After a bit of trial and error I finally managed to get it to work. Now locks on instantly! See the attached picture if you want to know how I did it. Not the best wire placement but it works great! You can try it yourself but be careful! Make sure you remove the motherboard from the rest of the assembly before soldering.

Edit: After some more experimentation, it seems that the upper contact point doesn't do much. So right now I'm only using using the wire that runs along the top. Still works great

[G2 Q&A, Help & Troubleshooting] K_s_K:
No you don't need to solder the wire onto the resistor. Just the two points.

I'm using the Sprint model but should be the same for other variants. The picture is actually a att model but looks identical to mine.

Don't have a camera but I'll try to get one. Had to use a pic from another XDA user.

Cool...I am gonna try it on my LS-980.

Thanks for your post. I finally have the LS-980 GPS fixed without any wire soldering. This is a simple fix. So it'll not void your warranty.

All I did was to rise the 2 contact point with wooden tooth pick so that it will have tight connection to the back cover contact points which are the GPS antennas. Just be careful not to break the 2 points. You don't even need to remove that camera cover.

I have the Verizon LG G2 and I had to send mine in for repair because I was experiencing the same GPS as everyone else here. I'm waiting to get it back and hoping LG truly fixes the issue.

Did everyone get their issue resolved after sending it to LG?
[G2 Q&A, Help & Troubleshooting] mrfil13:
I swapped to a red back and the GPS was good with a quick lock.

Took the back off as I had a feeling the raised bit for the GPS antenna on the back was slightly higher on the black case it came with.

It looks slightly taller on the black case, might be perception due to the colour.

Put the case back together then started having lock on issues. Pressing the area of the case helped briefly.

Just raised the pins with a tooth pick as advised, so far get a lock indoors within a few second.

I had GPS issues. I'm with bell and it's still under warranty so I restored everything back to stock and sent it away. When I got it back all they did was reflash the firmware. So when I got it back I tested it right away and still didn't work. So I had to send it away again and the second time they replaced the whole inside. The motherboard and everything other than the screen. Now its fixed. Get a lock within a few seconds. But I had to use my old phone for over a month. Frustrating but glad it's fixed now.

I also have issues with gps. I don't know why, but when I turn on Yanosik app (polish app for traffic, and police speed control placement) GPS locks pretty fast (within 10 seconds with 15m accurracy which minute or so changes to ~5m). Here is the link, check if it will help you https://play.google.com/store/apps/details?id=pl.neptis.yanosik.mobi.android&hl=pl

The experience isnt constant, but I found that without Yanosik there is huge problem with gps lock which takes often more than few minutes. When I open only google maps it's really hard to use. I've been doing some research comparing with my samsung tab pro and old evo 3d (which has amazing gps compared to almost everything) and results where always similar. When I really need gps, it's complete crap though. Murphy's law at it's finest;D

The problem is that I bought 32GB imported from other country (there is no 32gb option here) and basically I can wipe my butt with warranty...;/

The GPS is not fixed... but at least my phone looks new... :-/
[G2 Q&A, Help & Troubleshooting] HCFL:
A possible fix!

I may have a possible fix.

It starts with pulling the case off the back. In my case, the D802. I used my thumb nail (be careful, I pulled it off the skin pretty bad) and started at the top right corner and worked my way to each side of the Sim card slot (its important not to pry from the Sim card slot, else you risk too much pressure on the case and cracking it).

Once the case is fully off, there are four sets of contacts on the back of the phone. Take a sharp pointy knife and a pair of tweezers. Hold the metalbpad with the knife point and pull the contacts up with the tweezers. Don't pull too hard or you will risk breaking it entirely. Pull just enough that they move up a millimeter or two.

Put the case back on and restart your phone. Use an app to reset GPS data and redownload. Do another restart and try to lock. It still takes 20-30 seconds to lock but now at least it does.

Sorry for no pictures, I was in a hurry to see if it worked. Its not a humongous improvement but it does increase the likelihood of locking onto a signal.

Cheers!
[G2 Q&A, Help & Troubleshooting] scifoso:
bad antenna contact

The problem is with a couple flexible contact pins not making a good connection with the antenna ribbon. The fix is pretty straight forward and simple, but you should be careful. I ran into this as I found I could squeeze the back plate and I could pick up a satellite. After removing the back plate I just touched a screwdriver to the GPS contact pin (lower one) and within a few seconds a satellite was picked up.

So when looking at the phone, at the top right corner is where the GPS antenna contact point is. Lay the phone down on it's front and remove the back plate. You'll see a couple small, flexible pins on the circuit board at the top left (phone is flipped over, so it's opposite of looking from the front). On the back plate, looking at it as if it were on the phone and you are viewing normally, you'll see a couple of small copper rectangles (very small). The antenna is a flat ribbon that runs along the inside of the top corner of the back plate. A bit of the ends are exposed. The exposed parts press against the flexible pins on the board. If you look at the back plate and the rest of the board, you'll see three or four more of these type of antennas and flexible pins that are used for other radios such as cell or WiFi.

Do not touch any of the pins on the board as they are quite fragile. If the ones for the GPS do not look like the others (squished or bent or broken), then the fix will be more involved.

The fix is to use something very thin like the edge of a knife and carefully lift up the end of the GPS antenna ribbon that has the exposed copper. It's sitting on top of a small raised portion of plastic on the inside of the back plate. Lift up the end a bit, and then place one or two small piece of black tape on top of the small raised portion of plastic (sandwich it between the plastic and the antenna end). Make sure the pieces are cut to the correct size, which is just a couple mm by a couple mm. Press the end of the antenna back down and gently put the back plate back on.

By placing the tape under the end of the antenna, it is raising it is pushing it out a bit from the back of the plate, which will make it closer to the contact pins on the board.

I've fixed bad or no GPS signal this way on a few LG G2s as well as a Nexus 5 (whose design for the GPS antenna and contact pins is pretty much identical).

After this type of fix, I've ran GPS Test and satellite started locking in within 10 seconds. GPS on these devices actually works quite well when the chipset can get a signal. :)

If a contact pin is broken, it appears that it can be replaced, but I don't know where you would get one. For one phone I repaired the pin was squished and wouldn't prop up. I ended up soldering small piece of solder onto the contact. It's a hack, and it would probably have been better to solder something that is metallic and flexible such as a thin copper wire.

I see im not the only one... BUT LOOK OUT!!!

Removing back cover dont help !

I had problem with GPS, I send it to LG Service, 3 times they changed back cover and motherboard.

Everytime I tried the tweak with thosed connectors in back cover - which connects antena.

Sadly it never helped, nor did adding some paper under it to make it contact better.

Finaly the third replacment of mobo+back helped alot.

But! after month or so, the gps came back to the old state, not sooo bad like for the first time but not so perfect.

Im thinking that the algorithm of Google Location with help of wifi/gsm towers is messing my gps.

When I turn those off the gps start to work better. We have alot of mobile-moving hotspots with same names/mac address/channels, which probably mess location at Google Location.

Turning GPS to low power mode helped sometimes.

[G2 Q&A, Help & Troubleshooting] avink:
after noticing the GPS issue with a Telus D803 G2 I purchased used from Kijiji, I tried the paper method to no significant improvement. Also tried lifting up the contacts and had no luck. But given that it seemed likely that there was no proper contact with the pins and the battery cover, I decided to try something. Took an approx. 3mm long strip of 12g copper wire and placed it over the bottom pin of the GPS connector thingamajig, so that it was touching only the bottom pin. I placed the back cover right over it to sandwich the piece of copper wire in place. Since that point, I have been getting quick GPS locks (<10s) and accuracy of 10ft, which is believe is as low as the accuracy goes in GPS test. So far, seems like a success - hopefully the piece of wire does not move around but I believe it was sandwiched in well.
[G2 Q&A, Help & Troubleshooting] whittikins:
This is exactly the conclusion that I came to. If I change the setting from high accuracy to "sensors only", the GPS and navigation works great. If I set the location to high accuracy, the GPS location and navigation has a very hard time locking on and staying on course. It also keeps saying that it's lost GPS signal occasionally.

The weird thing is that if I'm in the maps app, and I'm not even navigating, I can see my location, and it's perfectly accurate as I drive down the road. However, if I'm actually navigating, it has my location correct when it starts, but then quickly shows the big blue circle next to the navigation route and won't lock on.

The phone clearly has my location with the GPS, but it's like the networks are confusing it and throwing it off constantly. This really has to be a Google issue, right? Maybe it's a problem with the fused location, but it did not used to have this issue. My brother's Nexus 5 has the exact same problem. So does my girlfriends LG g2. We both have the AT&T models. I have checked the GPS signal many times with the app, and it has a signal that is plenty strong.

It seems like it works better when I used the stock rom, but right now I'm using the g3 ROM. I might try going back to stock with the KDZ flashing process and test it tomorrow. I've even tried some of the apps like GPS fix etc., but none of those really seem to help the navigation problem. The phone can find my location without a problem, but the navigation is what keeps screwing up constantly, whether it's starting the navigation or keeping me locked on location.

Did you ever figure out a solution to this issue? Maybe modifying the build.Prop or GPS.Conf file would help?
[G2 Q&A, Help & Troubleshooting] sapsa:
Hello,

Sadly I didn't find good solution. I'm all the time on stock rom, reflashing will probably help because you will clear its 'wifi location cache'.

I stoped using gps enabled apps latly so I can't realy say much more in this topic.

Few weeks ago I was using google maps navigation, sadly it wasn't that great with those gps problems.

Non of GPS Fix programs out of market did help here - I use them only to check if the gps problem is based with bad back wiring (Im using them to compare same phones satelites stats, like how many dishies im seeing and using).

Maybe Android 5.0 Lollipop will help but if G2 getting this update is unknown to me. If not theres allways rooting just for hell of fun.

My Phone also had horrible GPS signal quality. Then it stopped working completely. Send it into service and they sent it back with the notification "GPS broken, no repair done". Thank you very much! Extremely helpful!

So I sent it back in again and this time they changed the mainboard. Now at least I can get a fix every now and then but the signal quality is still ridiculous. My 2011 SGS2 has better GPS reception. How could LG **** up so much with that?

It really seems like a hardware problem and I seriously doubt, that Lollipop will change anything about that.

[G2 Q&A, Help & Troubleshooting] MarkusMcNugen:
I use to have this issue on my VS980 with any ROM other than stock LG firmware. I found I was able to get a better fix by using the gps.conf from the stock firmware on any custom ROM I tried. At least got me decent enough reception to use navigation with the occasional error here or there.

One day it just started working, I have a theory that it's related to the spring used in VS980 variants for the GPS connection, and me screwing around with my phone by picking it up and dropping the back side of it into my other hand (Random bored habit). I swear after doing that one of those times, I can now feel a little springy sensation whereas before there was nothing.
[G2 Q&A, Help & Troubleshooting] Formhault:
I've owned so many Android devices so far... about 10 or so.

Not ONE was able to get a lock with only the GPS chip enabled. They would simply fail to acquire a location fix unless I enabled data. Well... actually, they would - on some occasions, they would get a location fix - but very rare.

Not sure if it's due to the satelites' location at those exact times (damn, lucky me), or the phone itself...

Anyway, you gave me an idea : to try out GPS, without mobile data. See if it acquires a fix... in less than 3 minutes (for f***s sake).
[G2 Q&A, Help & Troubleshooting] Compass Linux:
Formhault,

You're correct. Once I enabled carrier data, GPS quickly found a lock.

I wonder why it doesn't work with wifi (sometimes it does, but it's very rare).

Later on I disabled carrier data, enabled GPS and tried again (using "device sensors only") and it worked. Took a bit longer though. My theory is that you need to enable carrier data only once for the GPS to work, as long as you don't reboot.

Because of my impatience I left some scars on the phone, near the SIM tray, because I used metal tools to pry open the case. When I noticed that I could actually crack the covers I switched to an old plastic card (like a credit card) and it worked wonders. Perhaps I did the paper fix unnecessarily, but my device is almost one year old, so no tears were dropped.

Thanks for the tip!

I think your theory is wrong.

In my mobile contract data is not included so I had it never enabled. And I use always GPS only. I just make sure I update a-GPS data via GPS-Status app before I leave home if I need GPS.

[G2 Q&A, Help & Troubleshooting] Compass Linux:
So you update the GPS data through wifi?

When using wifi at home, very rarely I got GPS to work (mainly using GPS Test).

I'm wondering if my routers firewall or NAT is the cause, but I'm not at home right now to test.

Does anyone know if GPS uses a specific port? I can easily forward it if necessary.

[G2 Q&A, Help & Troubleshooting] tropenfrucht:
Yes, update aGPS data via wifi before i leave home.

With GPSStatus you can see how old you aGPS data is. So if you update through the app you can check and turn off mobile data before you do so, you can check if the update via your wifi works.

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!
[G2 Q&A, Help & Troubleshooting] Formhault:
The tip? The tip = enable Wi-Fi / Mobile Data when using GPS? No. That's not how it should be!

The phone should be able to acquire a GPS lock with the GPS chip alone, without an Internet connection. :(

---------- Post added at 02:10 AM ---------- Previous post was at 02:08 AM ----------

How? And where would that data be stored?

I don't think so. Every time when I'm connected to a Wi-Fi hotspot (not only my home router), Google Maps is able to get my location. Wi-Fi is always fastest (and most precise) at acquiring the location (obviously).

Well... unless your router / Internet connection is really weird, lol.

I don't know of any such port. But... as I said above, it always works via Wi-Fi. Some times faster than others - perhaps due to the quality of the Internet connection of said hotspot...

---------- Post added at 02:18 AM ---------- Previous post was at 02:10 AM ----------

I already had that app installed. Probably installed it some time ago, with the intention to use it some day just for this kind of tasks.

I checked the settings - it was supposed to download new AGPS data every day. Guess what? AGPS age was -- (so... non-existent?).

Regardless. I reset the AGPS data and downloaded new one (allegedly). Will check the GPS performance tomorrow.

If this works... it's funny that you need to go through these steps to improve the GPS performance. Performance which should be top-notch right out-of-the-box... :eek:

What would be interesting is to compare the signal levels of the top 2 or 3 satellites between the S5 and G2 outdoors. I suspect the S5 will be much higher. My G2 highest levels are in the low 30's while I have an old Moto Bionic which is 8 to 10 dB better.
