Hey everyone, so I have an LG v20 H918 T-Mobile model that came with h91810j stock and I rooted it recently and have twrp installed. So I've noticed that when I connect my phone to any bluetooth device while it's in my left pocket the bluetooth cuts off really bad especially during a workout in the gym which is where it is the most annoying and eventually disconnects. I've also noticed that if I hold the top of my phone while using navigation or leave it on my lap the gps cuts off as well. Is this most likely a hardware issue or can this be fixed with a later update like rooted h91810p or h91810q update (I really don't want to attempt updating to those firmwares until a exploit is found since I don't want to risk flashing it incorrectly and have the rollback feature screw the chances of root/twrp). If anyone has any solutions that would be great! I should also mention I'm currently running latest Megarom and H91810k base and have restored a backup through twrp back to stock rooted and had these issues on both! I also replaced this v20 for one that had the h91810q update without root but the thing is my other phone didn't have these issues and seemed to be more accurate on gps pinpointing my location and worked just fine with bluetooth and never cut off like this. Thanks again!
Rooted 918j and have gps issues as well. No Bluetooth issue noted. Im on latest WETA ROM.
I used to be on Tilde's ROM and had GPS problems as well.
Im on 10j with OvrDrive's rom and no bluetooth issues. GPS I have network and wifi turned off.
Thanks for the response guys, I'll test the roms you guys mentioned and see if the issues are still present and report back if the results are different. I guess worst case scenario I can swap out the phone again for these issues.
Update: So I tried other roms and the problem still persists, I'm going to assume that this is a hardware issue because if I hold my phone right next to my bluetooth headphones and hold the phone sideways with both hands it ends up cutting off bluetooth completely kind of like a death grip so I'm going to exchange it when I get the chance. Thanks for all the help!
Did you replace your plastic trim recently or buy the phone used/refurbished?
I've found that aftermarket plastic trim (e.g. being sold on eBay) might not have the same contacts as original trim. This is important because antennas are housed in the plastic trim (probably because the back of the phone is metal so optimal antenna placement is likely in the top/bottom ends). I figured this out the hard way after replacing the top and bottom plastic trim. After I did this I could not get a GPS lock and BT connection was weak. I looked and found the replacement top plastic trim was missing some contacts and just had bare plastic instead.
After restoring the original plastic trim these problems were fixed. I ended up replacing the bottom trim since it seemed to have all the right contacts and my GPS lock seems a little better.
I was going to make a post on this and post pictures but this is a new account and I'm still not at 10 posts.
Now that you mention it i did replace the back cover but no plastic trims.
If you had better reception before replacing the back cover, maybe it's checking/cleaning the contacts on it.

I reverted back to 10j because Bluetooth on 10K is spotty for me at least.
My phone has been having weird GPS issues recently where it was starting to take up to 5-10 minutes just to get a lock using GPS only. Using GPS toolbox it is finding upwards of 15-20 satellites but it just won't lock on to them. After switching over to high accuracy mode it was back to locking on almost instantly for awhile and now even that is starting to take longer and longer each day to acquire a lock.

Yea for me this problem is on both 10j and 10k. I might just swap out the phone just to get this problem resolved.

OK, after being so annoyed with the Navigation on this phone not working, I finally found a fix that is working for me and I am in shock that what I did produced a working GPS. First, anyone who doesn't know how to take apart the black cover (not the battery cover) do a search. Next, after removing the cover, the GPS Antenna without a doubt is one right next to the power button. I found this out by putting a piece of electrical tape over every gold connector that touches an antenna, then closing the black cover, turning on the phone, running gps test, and after trying different spring connectors, I noticed I had the correct one when the app GPS Test couldn't locate any satellites. Next, I also noticed that on the inside of the cover that I took off, the one that requires six screws, there is a silver looking strip that is supposed to make contact to the connector that has a full metal top part, so when the cover goes back on, the silver strip must make contact to this negative grounding harness top. I added a bead of solder to the silver strip on the inside of the black cover so that I knew it was making contact. I believe that this is a source of everyone's problems with navigation. That strip must be a shield and the design doesn't look like it makes good contact to the connector's ground metal plate. You'll see what I mean when you open the cover.
Next, while I had the cover off, I wrapped a 30 gauge wire around the gold spring pin that connects to the GPS antenna and ran that wire down the side of the phone right along the PC Board in hopes that it extends the antenna. I just ran it like 3 inches and remember, I ran it down, not up. The GPS antenna already goes up. I put a tiny bead of solder on the wire where it contact the gold spring contact that is attached to the PC Board so that it does not come off accidentally. And believe me, it is really simple. You cannot mess anything up. Just a dab of solder is all it takes.
I put the black cover back on, and then ran the GPS test app and at one point I had 12 satellites read and used with a 7 foot accuracy!!! Next I went to the Navigation app and started playing around with different addresses and my navigation WORKED!!! I am still in awe three days later. I drove from New Jersey to Rhode Island yesterday and had the Nav running for the entire trip. Only one time did I get a small circle about the size of a half inch which lasted for 4 seconds. At that point, I was driving though a forest type side road with limited sky view.
Please try this fix for anyone who has Navigation issues with their Nexus S and let me know if it fixes it.

Awesome. Samsung should have hired you before they released the Nexus S and 1st-gen SGS phones. My Captivate never had reliable GPS. I might as well have had Ray Charles giving me directions.
Funny thing is Google nexus phones are bugged...
Nexus one multi touch bug
Nexus s compass not working...
I think the issue here is with whoever was choosing and picking the hardware that would have powered a nexus...
HTC and Samsung do not surprise me... But Google not testing the compass on a flagship phone before releasing scares me :-\
Luckily my gps works fine (i9023 here) but the broken compass create a lot of troubles with gps navigation as very often the phone thinks to be driving in the reverse direction...
The nexus one digitizer wasn't a bug. Just a crappy digitizer. It worked as it meant to. It sucked but wasn't a bug.
The GPS and compass issues for the nexus s are different as well. Some devices have crappy ones and apparently don't work. My GPS and compass works perfect on the other hand. Always has

I don't have problems with navigation, even tho i hardly ever use it. However, this compass thing; I downloaded an app called Smart Compass and it works really well... Where I know it's north, the compass points north and so on. but mind you, I got my phone after companies stopped selling it so I might've gotten the last of the good batch
Could you post a photo of the finished fix so I can check if I'm going to fry something ? Thanks !

I should have at the time of doing it, but I didn't know what i was doing was going to work!! Now I have to take the phone apart again, but you give me a reason to hook up my Touchstone from the Pre while the phone is open and accessible. I will do my best to put the pics up in a timely manner and in the meantime, if there's anyone out there, go to the iteardown fix it (i think that's what its called) and look at the video or pics of the Nexus being taken apart.
Again, I have no reason to believe that I didn't fix the problem as it's working everytime, when it wouldn't work at all before the mod. When you're looking at the phone from the back, the GPS antenna location has a letter G engraved into the black cover after the battery cover has been taken off. It's right below the electrical type tape that covers the antenna FYI.

What does that do by the way.? Because my mod works everytime and you never have to use the code you just put up. Even though I appreciate you putting that there. Also, what type of problems were you having with your navigation? Did it work periodically? Did it never work like mine? Just curious as to the problem you had with your navigation. Thanks
Dan
I can confirm this hardware mod fixed voltages gps. He's gone thru 2 nexus s phones and both GPS would constantly lose the position every few minutes then reacquire, and show a huge circle for his position. Somehow this hardware mod fixes some design issue with the nexus s where a shielding isn't properly grounded. And also he extended the GPS antenna with a wire for good measure.
By the way it was the sprint nexus s 4g he modified.
Please post pictures to go with your narrative. I would like to try this!

wipe gps data. not the same thing as the gps status wipe (which didn't work for me). try it, doesn't really hurt anything. seems a software code is worth a shot then opening up the phone you know?
Some ROMs it never worked. Other ROMs it was sporadic. When I would get it to work, it always eventually "lost" its ability to lock, etc.
But hey.. if you want to get all hyper-sensitive over your mod.. go for it. Was just throwing another method out there for the faint of heart.

I am sensitive as I cried at your remark, and then I got really hyper and started running in circles with joy that my nav works. So I guess you're right, I am hypersensitive! Btw, I was being nothing but nice to your reply. Its OK. I forgive you.
Pics requested
Check out the pics. One of them shows some solder on the silver shielding so it makes better contact with the connector when they close back up. The other shows a 30 gauge red wire soldered to the gps pin and running down the phone. Hope this clears up what you guys need to do to get the gps to finally work on this dag gone phone.
.I've been using navigation and never had such a problems.my gps always locking under 10sec and doesn't loosing signal.
Btw i live in UK and using nav in big city.
Do a search for Nexus S 4g on sprint nav problems and you'll see a whole slew of people with problems.

Yeah, I know the title said GPS, I'll get to it in a bit.
I got a Verizon S5 early on and I have a 64G card that I use for music storage. I Bluetooth a lot to my car in a my 1 hour commute. Almost since I got this thing, the music has skipped semi-randomly. Seems like it did it at a specific spot in the road, but most likely it was just random. Some days were way worse than others. Research indicated this was not an uncommon problem with android. Tried lots of things, but like prayer, who knows if it worked or not. some days maybe yes, some days maybe no. This same memory card worked flawlessly in my AT&T S3.
Then I noticed the GPS was wonky. I got a GPS test program and determined that only pulling the battery out would fix the weak reception, and then only temporarily. This went on for a week, so I called Verizon and a "tech" recommended I do the dreaded factory reset. Did it..nada, nil, zippo.
During the frequent removal of the battery to do a soft reset, I damaged my "KLIX Hard Case" by Empire, so i ordered another one. I used the phone with no case for about a week and had no GPS issues, but did still have BT music issues when played from the SD card.
I got the new case 3 days ago, snapped it on and the next day noticed GPS was out again. I kept removing the case, slowly snapping it down and confirmed GPS went away only when the case was all the way on. During this testing process, the power button finally quit working. A reboot via battery removal revealed it was hardware related (couldn't turn the $#@ phone on). I gave it a thought, and opened the back and pressed on the plastic near the power button and it started working. I then, after some experimentation and a few beers to get my fortitude up, placed the phone, screen down on a hard flat surface and began pressing down on the plastic near the power button with some force. I heard something snap into place.
No more issues so far, with BT music or GPS with or without the case installed. Pretty sure GPS is fixed, but need another week to verify BT music.
My best theory so far is that because the phones chassis is made of plastic, and the buttons and antenna are in that plastic chassis, and the main board sandwiches between the screen and the chassis, that the very rigid tight fitting phone case was slightly deforming the chassis, causing it to bow upward slightly, aggravating an already bad contact situation between the mainboard and the chassis. I other words, the phone case was squeezing them apart. There is a possibility, that I will not pursue, that the main board was not snapped down properly at the factory. Since there are many touch only connections (antenna, buttons, card slots) between the main board and the chassis, A poor snap fit would make this a possibility. You can see how the phone is assembled here in this tear down pic.

Anyway, I thought I'd post this for folks trying to track down a similar problem. Hope this helps someone. Don't crack your screen on my account. :crying:
EDIT: Bluetooth music is dropping out again, both from the card and the internal storage on the phone. So bad this afternoon, I turned it off, It was fine this morning, so none of this fixes BT streaming. GPS still works though.
So i bought 2 nexus 4's a couple of months ago (cracked digitizers) and replaced the front frame/assembly with some i bought on Ebay.
They work fine except for the GPS. Both the phones are not connecting to the satellites. I downloaded GPS Status and GPS status and tool kit (or something lie that), tried resetting A-GPS downloading GPD data and nothing works.
I use co-pilot offline GPS and the phone is set to devices only to only use the GPS and not data. Co-pilot never connects with gps.
And both GPs status apps are stuck in "looking for GPS location" eternally. With Fix/Sats always staying a 0/0. I use to get 0/26 or something along the lines, but after resetting A-GPS a couple of times it stays at 0/0.
Since both phones present the same symptoms I started suspecting the front frame/assembly and found this : http://forum.xda-developers.com/nexus-4/general/nexus-4-gps-fixing-screen-replacement-t2895111
I wrapped the digitizer IC in foil like the guy did and it changed nothing. so i want to try and find some copper tape and layer up the contact points on the back cover in case the antennas don't make good contact. Do you think this might be the problem?
Also i flashed CM 10 on one of the phone in case it was an android problem, but i get the same results in CM.
Any ideas? this is the only thing that is not working on the phones and I would really like to get them working.
Thanks!

It seems it is a grounding problem between the frame, the board and the back cover. Mine is still not working but i had a little success with switching the conductive pads from my old frame assembly. But after a while something must have moved because I am not getting any gps lock anymore. I am waiting on some conductive tape to fix this.

The Gps reciver working perfectly....if you cant find satellites then your devive need service or replace...you dont need 3d party apps...Im using Igo and sygic and both ran excellent...
Mine is acting weird as well. Mine is tmobile version. I found that toggling location off and back on helped but we shouldn't have to do that. I'm probably going to have mine replaced if it persists.
I thought that maybe I was having an issue but now I think it has something to do with the pipes and towers, and blast resistant buildings where i work. Wasn't an issue with the Notes i had. but outside driving its fine.
I guess I will try a factor reset and if that doesnt help, I guess its time to figure out how to get a replacement.
I was having issues where it keeps thinking I'm home when I'm not
I'm still having frustration with gps. I have an Alcatel idol 3 that gets much better gps signal than the v20 running "gps test" from app store. I still get "searching for GPS" message in google maps from time to time in locations my other phones have performed flawlessly. I had a similar issue on the g5 and had to trade it for refurb which fixed the issue. I really dont want to do that with the v20.
The antenna is in the plastic trim at top which you can remove with 4 screws. It could be ours have a weak connection there or it could be a lousy solder joint on the underside of bga (ball grid array) chip.
Major problems with a two month old V20.
LG says they will not honor warranty because phone was sold as an "unlocked" ATT.
Also say that they show IMEI as activated two years ago!
This was brand new from newegg.com. How could it be activated two years ago?
Tremendously frustrating.
The top plastic cap in the H918 contains multiple antennas. Other models of the V20 which work on other frequency bands often have different antennas in this endcap, so when you replace it you need to select one for your particular model. Unfortunately the ebay sellers don't seem to know what cap to supply so often list the wrong models for the caps they are selling. The end cap connects to the phone's sprung metal contacts with either metal or conductive plastic pads, six in total for the H918. When I replaced my endcap GPS stopped working completely and picked up no satellites, on examining the replacement cap two contacts were missing which must be for the GPS - everything else seems fine (or I haven't noticed if some of the frequency bands are missing). I have attached a photo of the contacts in my phone and the replacement cap so you can see the problem.
I am now having difficulty finding a seller of the endcaps who can supply the correct part - I will keep on trying.
Been a loooong time since I've visited XDA....ah the memories, anywho, I have ATT LGV20 (keep it for removable battery and 2nd screen), The oreo update totally borked my GPS, it it always turning off and on, on its own and I get annoying location accuracy pop up which I have to agree or disagree to a lot.
It could just be big brother spying on me too I guess...
Any thoughts without doing a factory reset? I do NOT have root, though I wish I did. It is a refurb that was working fine before Oreo. Maybe an app that will monitor what is turning it on without root?
Thanks guys, happy holidays.
I remember trying to use this tablet solely as a GPS for my car, it never quite worked alright, I thought it was the Lolipop upgrade then I thought it might be something wrong with the antenna hardware.
It finds my position, with approximately 100 meters precision then it keeps jumping around up to 300 meters, things gets better while moving but it has no clue what direction I'm going when I come to a stop.
I have tried many apps and tweaks to fix the GPS, none have worked. I remember the GPS working once when this tablet was new,
that's it, or maybe I was hallucinating?
In all these cases the tablet was using a stable internet connection in my car.
Tried Kitkat, Lolipop, custom and stock kernel :crying:

So true. Gps sucks. Not accurate and takes long time to get the position.
Now i am not even able to use my tab. It always freezes within few seconds after i turn on the tab. Tried every possible solution. Used custom rom, stock rom, stock kernel, custom kernel, flashed fresh rom via apx mode nv flash. :crying:
My tab even freezes in recovery and had to hard reboot it.
Even posted a thread in xda but no solution given by ny1.
It's not so bad with Kitkat, after uninstalling everything leaving the rom completely naked with the barely essentials to not leave it glitchy the performance is acceptable.
Got 41k on Antutu, the lowest score was memory which scored 57 lol.
I suspect this tablet does not have a proper compass sensor, I've changed and resoldered the antennas but it hasn't changed anything.
Seems like a problem with drivers or hardware level.

Lol I finally sorted it out.
Who would put a compass between a couple of magnets?
Exactly, it's the magnets for the flip cover making the compass sensor utter useless.
Removing them fixes the GPS issue. They're actually inside the tablet near the upper bezels where holds the pen.

You must take the magnets off, the compass is needed in order to make the GPS to work properly, get a metal object and stick it to the tablet.
That's exactly where the magnet for the flip cover is located, just carefully pry the tablet open and remove them.
There's two of them.
Please note you must take off the pen, the SD card and the flip cover to open the tablet.
You shouldn't have problems to open it up using ordinary tools such as plastic pry tool or even a credit card.
