It is not a hardware problem - in my case. I had locking issues on v20D and I am running v20H for 2 days. There is no gps problems anymore.

So before doing something on the hardware just try a hard reset or flash to v20H. So for me this was the solution!

hi compass. Youre right, the gps is a bust in the G2. "antenna mod" didnt work for me , i even bought broken g2's (vs980) off ebay to swap motherboards, they didnt work either. Ive given up. ive gone external bluetooth gps receiver . it will get a better lock than any android phone anyway since its not agps, all while saving on my device's battery. you can find them pretty cheap on ebay, and they have a small footprint. obviously they connect to my device wirelessly via bluetooth, so you wont notice a difference anyway, except a very accurate gps now lol.

btw, how did that flashable zip go?
[G2 Q&A, Help & Troubleshooting] Eagl3007:
I was considering getting a G2 but now that I see these issues with the GPS it brings back bitter memories of my first smart phone, which was also made by LG. I used to own the LG G2x (original android gingerbread) and it constantly suffered from weak gps right when I picked it up from the store brand new. At the time I told myself it must be something with the area that I lived and I got used to the phone and did not want to get something else since the hardware was top notch at the time. However now after reading some threads related to GPS errors users have posted it is clear that this is an issue with LG hardware. Having a quick locking GPS is a must for me since I use it for my commute and to find uncongested roads, etc. My current phone, Samsung galaxy s3 locks to gps instantly so again facts point to LG hardware being faulty or not well designed.

GPS antenna has 2 connector.

1- is it better I connect 2 separate wire to connect to them? Or 2 ends of one wire to 2 connectors? Or its enough one ends to one connector?

2- what happened If I connect GPS antenna to WiFi antenna?

3- is it better I use thin wire or strong and thick, or copper plate?

Hey! is this the fix of the Italian forums? I found something there, but translate didn't do a good job and couldn't understand well what the guy was saying, let me give this a try and report back!

yes, i was thinking sell my phone, but i found a italian movie in youtube talking about the gps receptor, and i found here a guy who spoke about to put a copper wire to up the contact between the cover and the phone... i tried and now its working withou problens!

sorry about my bad english ><
[G2 Q&A, Help & Troubleshooting] Elendil_23:
Hello there!

Well, this is what I did, I didn't see the idea on a video, can you please share it here? I saw the forum here and found this other idea here so what I did I grabbed a small gauge copper wire and made a "loop" like a spring and putted it over the bottom GPS pin on the motherboard, I covered the back plate contacts with black tape (electrician tape) and put the cover back on. The GPS signal did improve a lot, not immediate lock or lock inside my house, but it did improve a lot, now I can connect! previously I was just able to see 24 satellites with no connection at all, I've tried the gps.conf file change/edit and nothing, I also tried with fastergps, androidts, and topntp with no luck whatsoever, until I made the loop wire on top of the GPS contact made the difference.

I don't have any pictures, but I'll put some tomorrow, I can confidently say the issue is hardware indeed, poor design or bad chip, don't know exactly, I also tried putting a small gauge wire inside the protective plastic cover around the edge of the phone, and didn't do a thing. I haven't got the chance to get to solder the GPS contact with the wire or use termic paste, but I'll update when I do that.

So far so good, fingers crossed!

Hi!

Thanks for your idea [MENTION=5969690]K_s_K[/MENTION] but in my case didn't work. I did solder a wire, quite complicated deal with the wire inside the phone, but did it, before soldering, rock solid connection, after soldering it, nothing, no connection whatsoever. After screwing around more with it, and soldering some more, still didn't work, but then, putted the phone on the table and booom! rock solid connection, I closed the phone and now, nothing, yet again, no connection to any satellites.

I'm ready to throw the towel here, any ideas fellas?

I solder the wire in the pin connector and still doesn't work, very frustrating I'd said the issue is purely hardware, anybody has a solution for this?

P.D. My first attempt was to use a clean copper wire, but had a small spark and a panic attack afterwards... so I used an insulated copper wire (green) instead.

GPS locking issue after phone repair

I replaced my lcd assembly, and when assembling the phone all the parts on the motherboard side would not sit 100% as tight as before (due to the lack of adhesive I think). When putting the back cover on resulted in a not so tight fitted back cover. You could notice it especially around the "down" - button on the back.

I tried the solution to gently bend the GPS antenna pins upwards to achieve a better contact with the back cover. I also cleaned all contact surfaces and pins with isopropanol - and this did wonders. My GPS now gets a lock directly after I open a GPS app.

With lifting pin up I make some signal inside house but man with your advice totally scroow up, after reboot no any signal. Try Europe, "my country", generic,LG, nothing ... Global, Derek G. , generic, LG , same nothing.

By the way, live in Europe, use LS980 and also can't pick up any Russian satellite, sometime maybe one but only on short time KK 4.4.2
[G2 Q&A, Help & Troubleshooting] sapsa:
The lift-paper thing is real. BUT !!!! You need to put more paper if its dont work and its just temporary because antena is flexy.

How you can find out if this hack will help ? squish right top corner of phone with 2 fingers and you can track the results with software like: AndroiTS GPS Test

The Hack last for few months for me but now the pressure the lift gave is smaller and smaller and squizing help so more paper ;)

I have the same experience, wondering if I should try soldering a wire between them, or whether a replacement back cover would help.

Anybody know how lg fixed the issue? I assume they did in later batches!?
[G2 Q&A, Help & Troubleshooting] tekweezle:
Is your stock firmware at Android version ZVH or above? If not try upgrading. I don't know how but It fixed my gps. I did the cardboard raise the antenna you and it helped but not entirely.
[G2 Q&A, Help & Troubleshooting] sapsa:
Thinking about wire also. When sticking wire to lower pin I got sooooooo good results that its sad when I use internal antena - I even bought 2 back covers, but sadly that didnt help with anything.

I tried rerouting wire inside case so i could enjoy big antena, but placing it near battery or closing back cover gave negative results - which are still better than internal antena -.-

LG you should give us our moneys.

I Love my G2 so much but you made it GPS-disabled -.-
[G2 Q&A, Help & Troubleshooting] tekweezle:
Try updating the firmware to stock zvh or above. Like you my gps was non functional. Now it works better than ever.

Same here, just today do wire loop, case open over 16 satelit case close no one.
[G2 Q&A, Help & Troubleshooting] Chris_Z:
I made a tiny hole in the case and got wire go outside, so it is not shielded by anything inside.

The same problem here, but now I found the reason.

There are two GPS contacts 1 mm apart on PCB, the lower one now goes to antenna wire, the upper one is, ahem, undocumented.

The lower contact on inside of the case was removed, the upper one was left untouched, just in case.

When the case is open, the upper one on PCB is not connecting to anything and your wire loop on the lower one works.

When the case is closed, the upper one connects to "something" on the inside, probably to some other part of GPS antenna built-in the case.

Once I put a tiny bit of insulation on the upper one on PCB so it is forced to stay disconnected even with closed case, everything works.

I get 16 satellites indoors: 11 GPS and 5 GLONASS on average.

It is far, far better that it was even when the phone was brand new!

[G2 Q&A, Help & Troubleshooting] dweekie:
How did you route the wire? When it is dangling in free air, i get signal immediately. When i put it flat against the phone surface even with the back cover off, i completely lose signal.
[G2 Q&A, Help & Troubleshooting] Chris_Z:
It seems I can't find a way to post a picture here... any hints?

So I'll try to describe what I did:

removed the lower contact from the case with a razor blade (just cut it out, leaving the other one - because I was unsure about its purpose and tried to minimize the collateral damage).

drilled a hole, 1mm in diameter in the case, orthogonal to the case surface, exactly where the (now removed) contact was before.

soldered a very thin but insulated wire (20cm) to the corresponding contact on the PCB.

placed a bit of insulation tape over the other contact (2x3mm) on PCB (removing both contacts from the case would likely solve the same purpose, but I refrained the temptation).

routed wire through the hole in the case to outside and closed the case.

So technically speaking, the wire goes outside the absolutely shortest way possible, perpendicularly from the PCB, straight through the case.

The outside part of wire was routed freely, because phone itself is held in another protective case allowing the wire being a bit apart from the phone.

And BTW, I don't think it was a bad contact to original GPS antenna in the first place, raising the contacts didn't gave any effect. Most likely, there was some internal strain in the built-in antenna itself causing its gradual degradation to the point of total malfunction.

Hope this helps,
[G2 Q&A, Help & Troubleshooting] trsmtn:
thanks

Thank you very much, it works pretty well even without drilling a hole, GPS signal now is on 30-32, before was like 20-24. I just insulated upper contact, and tie a wire to lower contact. I think with a hole signal will be much better, but i am using my phone witout case so it would ridiculous looking. Using VS980.
[G2 Q&A, Help & Troubleshooting] Deksinjo:
Just today make 2 hole in my case and root antenna trough back case, remove stock anten from back plate and still when antenna is close to case ther is no signal from satellite but when loop remove-uprise from case ther is full signal even in the house. Look silly but work :D
[G2 Q&A, Help & Troubleshooting] dweekie:
Same thing here, I used uninsulated cable and cat 5 wire with the same effect. It works fantastic when the wire sticks out even though it looks ridiculous.
[G2 Q&A, Help & Troubleshooting] rpozzebon:
You need to isolate the original antenna when placing the wire/cable.

The original antenna is no longer needed.

DId they give you a brand new replacement? Or was it a certified refurbished unit?

I got my G2 on launch day, called and complained about the GPS, so they let me go to the store and get a new one. Since this was 2 days after launch, I knew it more than likely wouldn't make a difference since even the replacement would be part of the same batch, but I didn't want to wait until my return period was over to get stuck with a refurb for my 2 week old brand new phone.

Edit: By the way, by following the restore steps by KDZing back to the factory image, the root status does indeed go back to unrooted.

[G2 Q&A, Help & Troubleshooting] obladi64:
Hi,

So far I haven't cared with gps too much but I remember that once I used Navigator the Phone behaved a bit unexpectedly. Then I forget about it because I don't use gps daily. Later I used maps again with gps and I realized that blue circle is getting small to slowly and never disappeared. Then I looked after what can be other's experience and I found this thread among few.

To tell the true I am very disappointed and I think it won't have resolution because the signal itself is low. If it could be fixed it was already done by LG.

I plan to share test result later and show you how dramatically it is worse than of SGS4. Also I am interested how hi the signal in yours. I will use "AndroidTS GPS Test" program.
[G2 Q&A, Help & Troubleshooting] obladi64:
So as I promised I took some screen-shots. I did test on balcony and half of sky was obscuring and very cloudy. I mentioned it just for the fact.

First picture was shot on SGS4 15 second after test had started. The second was shot on LGG2 after 1 minute. Third one was done after another 10 min!!!. So it is terrible. If sky was clear the result might be better with 50 or 70%. It means that signal would be let's say 17 instead of 10, which is still very very poor.

There is one more thing. It was checked on stock ROM but result is same with stockMOD.
[G2 Q&A, Help & Troubleshooting] obladi64:
I continued testing in test and result is not fit to expectation. To any expectation. Only several (between 5 and 8) satellites are recognized and only few of them with orange signal bar. Also gps was lost sometimes. It is really shame. I am interested what "AndroiTS GPS Test" shows on your mobile. Please share it.
