That is interesting indeed.

Ever since the "springs" fix I get a consistent good signal even when driving for hours and never lost signal, what's weird though, I never get less than 5 meter accuracy on any of the testing apps, but with the hidden diagnostic menu I get better signal and accuracy. I don't know, my model is H850 maybe my firmware V20c-ISR-XX. has something to do with it... for one thing, it only supports Quick charge 2.0, I checked the voltages with various certified QC 3.0 chargers, but that's not relevant to the GPS.

BTW, did you get a good accuracy (better than 5 meters) when using the original cover?

Anyhow keep us updated if it turns out the new cover is good long term.
[LG G5 Guides, News, & Discussion] thetool:
My phone is Korean (rootable :victory:)

I got accuracy of 3m when using the copper mesh, but again only for a few days.

I will update. even now accuracy doesn't seem too stable indoors, but outdoors I get 3m.

indoors far from window I get about 10m-12m after stabilized.

I tested with iphone 7 - got 4-6m accuracy indoors almost instantly when far from windows :eek:

Strange. My GPS and cell signal dips low when i Touch the glass , and more strange, When i touch the glass part that's close to the notification LED the Cell signal increases from -113 db to -99 db

This this caused by bad Grounding? Because you speculated that the Cover it's just a Grounding plane

should i get a new back cover to test?

The covers you guys shows there is a patch near the LCD cable and the corresponding place it touches there is a Mesh that goes under the LCD flex cable, My cover and Midframe has neither of those.

Tried the copper foil adhesive tape this way.... the signal went even worse.

Find below some pictures of my "art":

Photo 1

Photo 2

Photo 3

Then I bought a new back cover, and the signal went significantly better. Almost as good as my previous phone.

There still space for improvement thought. I can't get a decent lock indoors, but outdoors give me a precision of +/- 10m. That's acceptable given what I paid for the phone.

My conclusions for now are: the biggest problem is definitely the antenna's ground (mesh), in the top right corner of the back cover.

My attempt with the copper foil should have worked, but it didn't. I must be doing something wrong.

With the new back cover, maybe all I need is to improve the other contact area of the antenna, between the LCD and the PCB. I'm not gonna do this for now for two reasons: firstly, I don't know what I'm doing... things with copper or aluminium foil tend not to work with me.... secondly, I'm satisfied with the results so far.
[LG G5 Guides, News, & Discussion] schumifer:
I have also lost a few hours doing and redoing the darn thing. The ideal would be to solder a little spring on the contact at the screen side.

I soldered mesh on the contact but it was apparently way to much and the contact bent, almost no gps.

Then tried numerous times with copper tape, it seems that my copper and the backcover's aluminium (or whatever that silver thing is!) didn't get along!

Then mesh that i only placed at the back cover and then put the phone together.

The last trick worked, but i a getting the feeling it is on a time lease...
[LG G5 Guides, News, & Discussion] captainscience:
Lol demystified...

I have two of these phones and just read this entire thread for about the 3rd time. I tried a couple of fixes and they worked for a little while. Best idea by far is the guy who mounted an external wire connected to the contact where the ground plane is supposed to connect. It looks like G5 Fury Road Edition.

My fix? Curse loudly and bang the phone on the gearshift a few times. This causes my GPS to work for 30 seconds or so. So far I broke both camera lenses but the cracks don't show up in pictures. And I think it's healthier... Temporary solutions force us to remember how to read street signs and navigate with dead reckoning. If the GPS satellite system ever fails, G5 users will be able to continue living normally while society crumbles.
[LG G5 Guides, News, & Discussion] cyobane:
Haha funny, you shouldn't overlook though that there have been (IMO major) clarifications in regards to the key contact points that affect the GPS signal quality.

At least for my phone, regularly cleaning the mesh contact, and eventually replacing the mesh with aluminum foil, has kept my GPS working for the past year. Yea, it's pretty poor quality and pretty annoying to have to do but, hey it works!

With my current aluminum foil shim workaround (in use for about 2 weeks) I need to occasionally squeeze the top edge of the phone to get GPS working again. I also need to keep a 3.5mm headphone extension cord plugged into the headphone port while I'm driving to keep GPS accuracy within 15-20m (which I find good enough for driving in general).

The hackiness is offputting but I dunno sometimes when I think about the things that I have had to repair to keep working, I have fallen even more in love with them because of the 'customization'. It's kind of a point of view thing though gotta accept a bit of self delusion in your life
[LG G5 Guides, News, & Discussion] ThePigletWhisperer:
Guys,

I had no gps for quite some time now and I was planning to try the aluminum foil trick.

After I opened up the phone I decided to just put the battery in place and to power the device on without the back cover to see if that would have an effect on the GPS.

As soon as I opened the gps app, immediately I got Signal and then in like 10 seconds it went to 8m fix.

I'm seriously considering just just taping the battery on the back along with the touch button somehow without the back cover.

Try it out and let me know if it works for you also.

BTW if you dont know how to power the device on without a back cover just use a small screw driver and touch the 2 lower left pins of the power button on the motherboard.

https://photos.google.com/photo/AF1QipPL1FEx-6VQn0yLl6B9NARcNvCUMtQjhoCfYmdL?hl=es-419I found the solution by soldering a piece of earphone filament directly into the contact on the motherboard. This filament has a layer of varnish so I could place it on top and avoid any touch with other contacts. The reception improved surprisingly obtaining an accuracy of less than 10 meters. I am very satisfied.

Could some of you please recheck their GPS on Oreo? Suddenly I find 15 satellites by an accuracy of 4 to 5 meters... But two weeks ago my phone crashed on the ground. So its either the crash (and will soon worsen again) or a software bug resolved with oreo.

Your volume keys will work fine now. Not a permanent fix.
[LG G5 Guides, News, & Discussion] optionalmgrr.la:
My volume keys always work, it was the GPS which can't fix any satellite even in open areas.

So what would be a permanent fix?

edit: ok so those are for volume controls... I'll leave that as-is until GPS fails me again and hopefully someone will post a really permanent fix .... thx!
[LG G5 Guides, News, & Discussion] Z23:
Oreo seems to improve GPS... But it will never work better than "okay". Unless you want to drill holes in the rear, solder at the contact or use foil behind a case there is no way to further improve your GPS.

Get finally GPS to work

I tried lot of thing on the small rectangle antenna in the top corner before discovering that the main trouble was coming from the ground connection, located in the back cover. I have added a small thin metal part above the connector (the gray one with the 2 holes, connecting to the red area on the image) and GPS is running again. I can get fix with 15 sats and 4,6m accuracy outside. Sometimes I can get 20 satellites in use.

Chris
[LG G5 Guides, News, & Discussion] semifast:
I'm sorry but I don't understand ? What is the red area ? You mean inside the red circle ? What is the grey one with 2 holes ? Is it in the picture ?

And what do you mean by "above the connector" ? On top of it, covering it ? Above it like next to it closer to the top ?
[LG G5 Guides, News, & Discussion] cricri207:
You see on https://d3nevzfk7ii3be.cloudfront.net/igi/3YBv66uEfRONBb4m.standard the small antenna in the corner (red circle) and the main antenna connector with the 2 holes https://d3nevzfk7ii3be.cloudfront.net/igi/tum3smWC1dBRqSWT.standard (green circle).

From my point of view, there is no need to make any change on the small antenna, just improve the connection of the main one and that is it.

Cheers Chris

You mean we put aluminium foil at loation 2?
[LG G5 Guides, News, & Discussion] cricri207:
I have just placed a small thin metal sheet (about 0.2mm thin) on the connector, fixed with same tape.

I think that aluminium foil is not thick enough.

[LG G5 Guides, News, & Discussion] bloodgull:
can someone post what the answer is and what the actual fix is? i have a "refurbished" lg g5 i am now stuck with that cannot get steady gps signal at all. (at first i thought it was a google location services issue so i didnt clue in it was actually my phone) i cannot make any sense of this thread its an absolute mess with all the quoting and conflicting information circling i don't understand any of it after lurking over the course of several months. i broke open my phone finally to replace the camera glass on the back and located the metal mesh and the other location labeled 2 but i cannot seem to identify any other locations posted here in various screenshots and pictures in part to bad quality pictures or lack thereof (talking about the guy that suggested soldering a new antenna) in previous pictures and also my lack of understanding how the picture labeled location 3 and how the copper post butts up against the metal mesh? there is nothing behind the metal mesh next to the headphone jack and if you are taking about the opposite side than that to me looks like it would be the opposite and wrong corner (upper left vs upper right) depending on orientation.???? again, could some one delete the false information and leave nothing but the actual correct fix in a post that makes better sense, would be appreciated as i am sure i am not the only one still confused about this. thanks.
[LG G5 Guides, News, & Discussion] djrichard64:
I've seen that Amazon has external GPS usb units (usually for the marine/boating crowd) at least one of which is compatible with android. I'm wondering about connecting up one of those to the LG G5 and homing off that instead. But the issue would be getting power to my phone, since the phone's usb connector would otherwise be occupied. Thoughts?

Edit: well I can think of one down-side right off the bat. Which is that I would have to tell the phone when to use the external GPS vs internal. Which for me would be the difference between being in the car vs outside, as my thinking on when to use an external GPS would be only when I'm in the car. Not that I can't do that, but I'm trying to come up with this solution for my father-in-law as well and the less steps for him, the better.

You may as well put that money towards a new phone
[LG G5 Guides, News, & Discussion] cyobane:
if the mesh is still in tact just try cleaning it off with a q-tip and some isopropyl alcohol. the mesh is basically just making contact with the metal back.

I ended up removing the mesh entirely since i cleaned it too many times and the glue holding it place came loose. I folded up a small piece of aluminum foil smoothed it out as best I could and fit it into the corner where the mesh was (after cleaning it up). So far, with Oreo, things have been working well enough for over a month now. I think the mesh contact is really the only contact that has problems but any way you can also clean the contact point just under the headphone jack and the corresponding point on the phone motherboard.

Attached a couple pictures of my job. pretty crap but eh it's been working!

I love the G5 but it having so many important connections between the main board and the back cover passing through extremely fragile connections is really a stupid design.
[LG G5 Guides, News, & Discussion] Capodoglio:
Hi all. G5 se h840 here. I had the issue, not from the very first time, but after 4 or 5 months of daily use. I even remember when it started, because I was running as usual, and it begun losing the signal. Since I have gps in my watch and don't need it too much while driving, I was annoyed but it wasn't a huge problem. A month ago I broke the screen, and since it's really easy to replace I did it by myself. And the GPS started working correctly again, having done nothing specifically to solve the problem.

Hope it can help someone!

When you say thin metal sheet, where do you get this thin metal sheet? What type of metal is it(aluminum foil)?
[LG G5 Guides, News, & Discussion] Z23:
Don't do it! A waste of money. I did it on warranty, it took me three weeks without my phone and worked the usual 6 month. It's a design fault and can't be repaired by LG.
[LG G5 Guides, News, & Discussion] XStylus:
I put a small ball of solder on the thing in the green box so as to put more pressure on the ground contact. Lot better than risking a conductive piece of copper coming loose.

Working okay so far, but we'll see if oxidation starts to inhibit it.

[LG G5 Guides, News, & Discussion] deathhilarious:
Personally I first used a piece of folded aluminum foil. The foil worked okay--huge improvement, but still not great (drops, drift, not great indoors).

Next I used a piece of solid core copper wire, which I hammered flat. 8 gauge wire was too thick and wouldn't let the case close. 10 gauge wire worked perfectly. I'm now getting excellent gps locks even from the basement.
[LG G5 Guides, News, & Discussion] rizzorizzo:
Thanks for all the responses. Where can I get the copper wiring? Home Depot? An old appliance or wiring? Do you solder this on or just place it in the groove. Thanks.

Hey guys,

I've had a same problem, the phone doesn't have a GPS signal. I have loose the motherboard's screws and tight them again, but gently. When I felt the screws was start pushing the motherboard, I stopped. Therefore the mobo is lifted up a little bit so it's closer to the metal case and now I have a GPS signal.

maybe he meant some kind of conductive compound.

Or, just fooling with the mesh could make the pin connect to the mesh when the phone is put together.
[LG G5 Guides, News, & Discussion] owenjm:
Hi all,

I've been trying to fix my GPS through cleaning the contacts as suggested here. Unfortunately, my gravity and linear acceleration sensors seem to have stopped working after closing the phone back up. I've previously opened and closed the phone several times without issue, and am always extremely careful handling tiny electronics, so I'm puzzled as to what I've done wrong. (I've reopened and closed the case several times since, with no luck ... I hoped initially it would be a problem with re-seating of some contacts, but seemingly not.)

Edit: an XDA search in other phone forums led to a couple of similar accounts of gravity sensors not working owing to corrupted modems, so I reflashed the modem. I'm not sure why the modem had become corrupted (I did try a new kernel coincident with trying to fix the GPS, so I guess it's possible), but reflashing the modem seems to have restored my sensor functionality for now and it's holding after a number of reboots.

A pity I still haven't got the GPS working perfectly, though. Even though all connectors seem to be making good contact and the contact plates are clean, I only get good reception when squeezing the phone where the GPS antenna is located -- pressing the back cover onto the mainboard seems to greatly improve the connection. I'll try a foil shim next, I guess (I seem to have a type "M" back cover which lacks the mesh completely).

I'm amazed that LG managed to make a GPS so terrible that even XDA can't find a reliably working fix after several years ... that takes talent!

Progress

I'm having a making a lot of progress using this connector (BLUE CIRCLE).

As you can see in the top left of the photo, I've really screwed up trying to solder on to the original pins/traces. However using the a wifi coaxial cable (£2 off ebay - click in connector) you can use this unused connector and get a great signal.

Either; link this to the phone aluminium frame, or like I am going to; use a long insulated wire as an antenna (Better than original)

I am using magnet wire to make these connections

Foil fix works great a 2nd time

Update: This procedure (adding foil to the two places circled in the image above) fixed my GPS issues entirely. I used the GPS for navigation for hundreds of miles and never had issues.

That phone recently broke for unrelated reasons (I snapped one of the tabs on the mainboard that connects to the chin – oops!)

I ordered another G5, which of course had the same GPS problem. I repeated the same repair as above and the GPS works perfectly. On my first attempt, the fix actually did not work, so I reopened the phone and inspected again. The mesh was so dirty-looking that I decided to just remove it, and use the folded-up square of aluminum foil instead. Works great.
[LG G5 Guides, News, & Discussion] ThePigletWhisperer:
Exactly same thing happened to me 3 days ago while trying to open the phone to fix the GPS.

I know there's no chance but i'll try to solder the piece back on.

If it doesn't work (which let's face it, it won't) I'll be buying a new phone I think.

Currently I'm using my ancient galaxy S4 which works just fine (including GPS, cough cough) besides being slow, So i might be buying an s8 when the s10 will be out. We'll see.

Oh and btw the folded aluminum foil worked for me also, so yei for me I guess:silly:

Device is H850 with official update to android 8.0. I have a little different issue with gps. The signal is good, even indoors the phone is catching location. BUT every several minutes it stops receiving signal and rediscover the satellites after 5-10 sec with initial very bad accuracy (sometimes throw the lock to hundred meters away for a second, after that for 4-5 sec it get again good location even accuracy 3 meters and on exact location). And that drives the navigation programs crazy. Often they start thinking that I am driving at some different road around. This happened even if the device is just sitting on my desk - no movement that can cause bad contact, at least not so often and not at so equal intervals. I already clen the pads and push a bit the contact and signal goes even better, but that regular stop and starting with bad accuracy is not going away. Does anyone have any idea how can be fixed this?

this sounds promising, i was thinking about a instant liquid solder/flux to brush on but since you mentioned 10 gauge wire i may try this or a combination as it sounds the most promising. One question, where? did you place this metal, same place the mesh goes? and would you recommend removing the mesh or placing it over the top, or a different place entirely? another thing is no one has given specifics on exactly how much foil to use, would a square inch be too much folded down to the same size as the mesh? please answer. thank you.
