Is my GPS failing? - Moto G 2015 Q&A, Help & Troubleshooting

Hello,
My moto g 2015 GPS has started playing up.
It used to work fine in the car, now it takes up to 2 minutes to get a fix. Then keeps losing it, the marker will be static and then go floating off over a field.
Seems to work OK outdoors.
I've downloaded GPS test, which shows it will only lock on to 4 satellites when on the dashboard of the car. It will get 11 out in the open.
I've reformatted, to no avail. I've enabled high battery use mode in location.
My last resort will be to try to uninstall twrp, remove root. And try to restore to stock. Then return it to the shop and hope the don't know it's been unlocked.
I know I'm bound to get better reception outdoors than in the car, but as I say last week it worked perfectly.
I'm all out of ideas.

I'm back
Just did a side by side with my original moto g.
The old phone locked on in 3 seconds. And was showing accuracy of 10feet in the app 'gps test'.
The 2015 locked on in 37 seconds then dropped out. With accuracy of 100+feet.
I'm starting to think it's a lollipop thing. Perhaps high accuracy isn't strong enough.? Or there is something in the APN, I tried setting the type to default supl apps as I saw this somewhere but this didn't work either?
Today I reverted to stock, perhaps I should try a different rom?
Is anyone willing to have a look and see how quickly they get locked?
Just so I know whether my phone Is normal or has a fault.
Thanks

I haven't had a chance to test in the car but in the center of the room inside I got a 3D lock in 2 seconds with 13 feet accuracy. At least some of your GPS features are controlled in the gps.conf file located in system/etc. This will be where some of your NTP server settings are located.

Ok Thanks,
After much messing about, here is what I've established..
The high accuracy setting isn't having any effect. The accuracy, and lock times are the same whether connected to WI-FI, Mobile Data, or with them switched off and the phone set to device only.
Could this be something to do with the NTP server settings you mentioned?

There are a number of free "GPS fix" apps available on Play. You could try one of them. I would make a copy of the file I mentioned to be on the safe side though.

GPS Issue

Is any one else having an issue of the GPS taking an extremely long time to get a lock?
Sent from my SAMSUNG-SGH-I897 using XDA App
Out of the box it worked flawlessly. I messed with a location setting and then gas took around thirty seconds to lock. I turned that setting back on and gas flew again. On average, my gps has a lock by the time the map loads

Could you tell me what your gps settings are then? Also could you dial *#*#1472365#*#* and go to application settings and spul or something like that and list what you have there?
I'd say that driving home the gps got a lock relatively quickly but it was only a lock accurate to within 50 meters. I guess this is good enough for driving but it wouldnt be good enough for biking or jogging.
Mine takes a full minute to lock. I think the issue, at least with mine, is that no matter what I do to the settings, their not saved. So if I go to settings and change location settings, or use *#*#1472365#*#* the settings never seem to save. Not sure if I'm doing something wrong or this is a bug, sure seems like a bug though.
I noticed the first time i tried to get a GPS lock it took forever. But every time since then it has been getting progressively faster. Now it locks and pulls up traffic info within seconds...
I am having a difficult time with the gps locking and it is very inaccurate. I went into the settings and change d the startup to cold
Sent from my SAMSUNG-SGH-I897 using XDA App
whoa, you get traffic info? is that with google maps?
I have been having the same problems. I tried messing with the GPS settings and it seems to have made things somewhat better, though I can't confirm it. Here's what I did, if you are interested.
Dial *#*#1472365#*#*
Go to SUPL/CP Settings
Set server to supl.google.com
Set server port to 7276
Set SUPL Secure Socket to OFF
Go back then go to Application Settings
Set Operation Mode to MS Based
Set Accuracy to 80
Set Use SkyHook to ON
I'm not sure if any of these things made a real difference at all, but I do know that right now my GPS is reporting an accuracy of within 10 meters in a location where I couldn't get a lock before. I'd love to hear if this helps or hurts anyone else's GPS performance.
Thanks this actually fixed my issue of not being able to ft a lock at all. Accuracy is pretty high at 30m but it was spot on in Maps.

Thanks for the tip.
the gps is still not working inside my house, but outside it locks faster outside.
Thanks

I've tried following the directions in the GPS Fix 101 thread under the Vibrant section: no luck... I tried what was suggested abouve: no luck...
Can someone tell em what I'm doing wrong? I know that usually the issue is w/ the operator, not the device and I'm new to Android. I like the phone, but GPS is a BIG reason I bought an Android phone. I need something that is REALLY accurate as we have smaller blocks in some of the towns I go to. Seriously, where my parents live there are A, B, etc. streets and some city blocks are so small there is an "L 1/2 St" ( You can laugh about everything being bigger in TX...)
I do a ton of traveling so this feature is VERY important to me. I just got back from one cross country trip tonight and seldom did I get a good GPS lock and that was on major Hwy's. How does this compare to the ARIA? My sister just got one of those, but hasn't messed around w/ it as it is her first Android phone.
I'd appreciate any help or advice anyone can give. Thanks in advance!!!
If it helps; I was just outside my father-in-laws house and it initially had me about 2-3 blks away in the middle of a golf fairway. It is a clear night, no clouds or heavy trees. I can only detect 1-2 sat.'s when I do a test, and I have a Bodyglove silicon/rubber case/skin.
Ok, I tried it again... In the house I'm about 500 ft off from where I really am and placed in a golf fairway. Outside I am FURTHER off: I'd estimate at least 5 blocks and placed in the middle of a different golf fairway. For comparision sake, my wife's iPhone 3Gs has her within 10-20' while inside the house. I can detect 3-4 sat's. which is the most ever, but it does not use any of them... To me, this is unacceptable and a great cause for concern. What can I do???

I changed my settings to the above, and I've gotten much better results with my GPS. It finds my location a lot quicker, and more accurate. Try these settings if you haven't already. If you have, I guess I would just take it back to AT&T. Having a lagging and inaccurate GPS on a smartphone can be annoying.

For the android newbie... can you give a little more detail on how to get here and Skyhook?
TIA
Never mind I found it.
Will/Can this be fixed.
I am very disappointed with my GPS performance in an otherwise very enjoyable phone.
GPS is important to me and I am seriously considering returning the phone. There are a couple of other issues, but I'm working through them.
Do you think the issue will be repaired? Guess at how long until fixed? I know it's all just a guess.

They above settings improved my GPS signal acquisition, however, accuracy was still very poor. This was extremely evident when navigating around town. I'm currently testing the following settings and so far things seem to be working well:
Go to SUPL/CP Settings
Set to AUTO config
Set SUPL Secure Socket OFF
Go back then go to Application Settings
Set Operation Mode to MS Assisted
Set Accuracy to 100
Set Use SkyHook to ON
Using these settings I can reliably track 8-9 satellites and lock 4-5. Accuracy tends toward 5-10 meters and signal acquisition is usually within seconds.
I've noticed that after changing settings it can take the GPS a while to acquire a lock. Subsequent uses improve in speed.
I'm by no means an expert on these settings so if anybody sees a problem with them please let me know.

Optimal GPS setting AFTER update

I would like to start a thread to discuss what is the optimal GPS setting for the Captivate after installing the update. From what I can see, the update didn't change my LbsTestMode setting at all. My GPS is now working pretty well, still can't compare to the HTC Aria I had before but acceptable. I wonder if we can further tweak the GPS setting to make it work better.
the only change i seen was if you check auto config it takes you back to server port 7275 and changes the server to a new one.
yesterday there was a thread started about those who got the update successful, and the guy did a test of his gps with screen shot. A) how do you track your route, B) how do you take a screen shot?
it looked like he was using the maps app but i looked all over it for a way to track my route!? thanks..

It seems that most people who had messed with the GPS settings before the update are not getting optimal GPS performance after the update (This is true even if they change the GPS settings to stock original that shipped with the update).
So moral of the story is to change GPS settings to stock before you update....?

Did you change your GPS settings prior to the update? If yes, welcome to the "group"
My GPS is definitely working better after the update. It used to take 30 second - 5 minutes to get a fix. So far I have been able to get a GPS fix within 15 seconds.
My settings are:
Tracking
S/W Test
MS Based
Cold Start
GPS Plus On
Dynamic Accuracy On
Accuracy 50
SkyHook On
PC Tool Off
supl.google.com
Port 7276
Secure Socket Off
AGPS Supl
As far as tracking my position with driving, it's not perfect but acceptable. At time the GPS would put me on the local street next to the freeway but not too often. It takes about 30 sec to 1 minute to locate me while indoor so I have no problem doing my FourSquares checkins.

Actually, I never touched my GPS settings prior to the update, and I get crappy tracks. I had a Captivate which I changed the settings on, but then I ended up exchanging it for a new one a couple days before the update, and left it exactly as I found it, and GPS is spotty as hell.
First of all, I'd like to thank you for posting this thread, it's exactly what I have been looking for. The other threads keep getting hi-jacked by people who couldn't get the update. Hey you knew when you rooted you wouldn't be able to get OTA updates, get over it and wait till someone figures it out.
Back on topic, my GPS is definitely better. I did change my settings before the update in LbsTestMode to the recommended settings. My gps locked quicker, but it was constantly losing the lock. So i used the shortcut method to go into LbsTestMode and changed back to stock settings. It was like the phone was set to lock at exactly 30 seconds, 30 tests with an average of a little under 30 seconds.
The accuracy was a little worse, 50m compared to 15m. But it was also losing the lock quickly, so I changed the spirent setting to supl.google.com. Now i lock between 10 and 15 seconds and it stays locked. My settings:
s/w test
standalone
hot start
gps plus- on
dynamic acc. - on
accuracy- 50
skyhook- on
use pc tool- off
custom config
7276
secure socket- off
agps- supl
So maybe the answer in the end, sad to say, is to buy an aftermarket gps device with bluetooth integration and bypass the built-in gps altogether.
I've been messing with the gps all day and cannot get a lock at all. Not even for a second. Messed with my gps settings before the update.

Two months in and I've seen hundreds of threads about the GPS on the captivate, The GPS its broken, no good, damage. Lets get over it and move on. We [email protected]$k BTW new update its a lil better but still sucks. My nexus one located me with no problem spot on. Change your phone why u can. I wish I was under the 30 day return policy.
Sent from my SAMSUNG-SGH-I897 using XDA App
The only settings I changed were the server before the update. I checked the settings after the update and I had Server as spl.google.com and Standalone in Operation Mode. I switched to autoconfig and those changed to some new server and I changed Operation Mode to MS Based as in jaimingandhi's link. Before I made those changes it took about 3-4 mins to lock on, now it takes about a minute, so not 15 seconds like others have said, but better. Will do more testing later. I count for two as I've got to Captivates at home. But it looks like different settings work for different people.
Edit: Tried again today, lock takes still 3-4 minutes and loses it constantly and there is no accuracy of location whatsoever.
I updated successfully and still had issues with GPS locks until I powered down my phone, removed the battery, sim card, and external sd card, replaced them, and then rebooted the phone. After that I was getting a GPS lock in 15 seconds or less and not constantly dropping signal as long as I had line of sight to the sky (a.k.a. through the windshield).

[Q] GPS takes long to lock in - Galaxy S 4G

I'm aware of the GPS issues with the Samsung Galaxy S. I have the Samsung Galaxy S 4G and I'm wondering if anyone with this phone is experiencing difficulties getting GPS to lock in.
Within approximately 10 minutes, I can see in the GPS Test app about 3 satellites in view. Given enough time, it picks up a few more and eventually locks in.
I've read about the Super GPS fix and the hardware fix but I'm not sure if it would be wise to try it on this phone since the fix was meant for a different model and I don't see any mention of anyone trying it on the GS4G:

Please share your thoughts and experience.
Locks quickly for me without any "special" settings or apps. I even have network-based location always off on my phone since I don't want Google tracking me all the time.
The first lock may be causing you problems if the orbital data hasn't been loaded recently enough.
I have read that GPS Status has helped some by causing the orbital data to be refreshed.

I have a Samsung Galaxy S 4G and a Vibrant, both are horrible with GPS, they both take forever to get a lock and many times they never get a lock and Samsung is less than helpful. They had my Vibrant for three weeks and sent it back with nothing changed.
mine has never taken more than ~30 seconds to get a lock, even if that 30 seconds sometimes feels like "forever".
this is my first GPS-equipped phone, so i don't have anything to compare it to, but once it's locked, subsequent locks take less time. maybe i just got a "good one"?
I have a Vibrant and an sgs4g. There is no comparison between the two. The sgs4g takes about 5 seconds to lock, The Vibrant I've waited literally 40 mins and still never got a lock. It could be the app. Are you having any trouble with google navigation taking along time or just the gps test app?
I know this wasn't directed at me, but I share the same GPS problems.
This issue occurs in all GPS Apps, including Google Navigation. It simply says acquiring GPS....
The GPS icon flashes like it's working, but its not doing anything.

Looking in the market there's an app called GPS Aids V2...anyone try it? Supposed to help all Galaxy S phones with GPS problems.
Before buying, I want to see if it's worth it......

Just kidding, I bought the app. So far it seems to be working well; after doing everything my phone was actually picking up FIVE satellites.
Not working right now, though. I contacted the developer for some help, and I'll post his reply/an update soon.

I have the solution and some confusing steps to fix your phone.
Right now as we speak i've followed ALL the steps and have 4 satellites currently showing on the phone while INSIDE my house, in under three minutes time.

-Download LauncherPro first.
-Tap and hold on your homescreen, and select shortcut.
-Click Activities.
-Scroll to LbsTestMode.
-Tap the first one, LbsTestMode (with gray saying com.sec.android.app.lbstestmode.LbsTestMode
-Click okay when "edit shortcut" comes up.
-Open the shortcut.
-Tap "SUPL/CP Settings"
-Change the following fields to...
Server -> supl.google.com
Server Port -> 7276
SUPL Secure Socket -> OFF
AGPS Mode -> SUPL
-Click Back (it saves it)
-Reboot your Phone.
-Click Settings, then Location & Security.
-Check "Use Wireless Networks"
-Go to your Launcher, and open LbsTestMode again
-Click "Delete GPS" Data
-Exit the App, and close it with a task killer.
-Open it again, and click "Get Position Test"
-It might take a while for something to show up....but it eventually will. Let it run for about ten minutes straight.
-Close the App again, and you should be good!
Upon Position test....I got:
Accuracy: 41 (meters)
Number of Satellites (INDOORS!): 9
Speed: (m/s)
If you have any questions feel free to reply.
Remember, credit goes to "Bade" (which credited XDA forums anywho) of samsunggalaxyforum.com
Running Copilot Live (GPS Application) and finding location took less than 5 seconds indoors.
To check some info out, I ran GPS Test, and saw "In View" Satellites was 9, and "In Use" was 7. (both were 2, to 0 respectively...previously.)
Running GPS Test (another app, different) came up with my location in less than a second.
I'd call this a success

My GPS was working but I wanted to mess around and check on your findings. I tried to get this to work but it took quite long looking for Satellites.
I noticed when I went in to modify the SUPL settings, it was set to custom config. Made the changes according to your post and like i said before, it took a while so I stopped it. changed the settings to auto conifg and BAM! pulled 13 satellites and locked in within seconds. I do not know if its due to my location but Im working great on Auto Config.
this post is more of an FYI rather than a fix. Hope you guys get yours fixed either way.

On the first try, you have to let "Get Position Test" run for around 10 minutes (The 3 minutes on the original post I said might've been a stretch).
Trying Auto Config, I'm getting similar results, though with the custom settings I had more satellite lock-ons.
Custom:
12 SAT, 10 CONNECT
Automatic:
11 SAT, 7 CONNECT
After doing this, the GPS data should stay downloaded on the phone so future satellite searches are MUCH quicker.
Thank you for your input by the way..I appreciate it
My phone has always find satellites and locked within 30 secs. One day I started messing around with settings and came to find out my gps was no longer locking on any satellites at least for 10 mins. I bought the gps aids v2 app from the market then tapped on gps doctor and tapped on "regenerate" (it regenerates the gps data folder) it made my phone boot up. Since then my gps has been workin excellent after that.

I tried the same thing, except with that app I couldn't download the XTRA data once resetting the settings :/
Me neither, it couldn't seem to download the xtra data, but just by tapping on gps doctor and "regenerate" and in my case that fixed it. Good luck!

If i get bored ill try it again, I live on a tiny island out in the middle of the pacific so GPS is not that big of a deal for me. lol
Thank you for the update. 10 Sat connects is way better than 7

I have the solution and some confusing steps to fix your phone.
Right now as we speak i've followed ALL the steps and have 4 satellites currently showing on the phone while INSIDE my house, in under three minutes time.
Credit to: (url removed)
-Download LauncherPro first.
-Tap and hold on your homescreen, and select shortcut.
-Click Activities.
-Scroll to LbsTestMode.
-Tap the first one, LbsTestMode (with gray saying com.sec.android.app.lbstestmode.LbsTestMode
-Click okay when "edit shortcut" comes up.
-Open the shortcut.
-Tap "SUPL/CP Settings"
-Change the following fields to...
Server -> supl.google.com
Server Port -> 7276
SUPL Secure Socket -> OFF
AGPS Mode -> SUPL
-Click Back (it saves it)
-Reboot your Phone.
-Click Settings, then Location & Security.
-Check "Use Wireless Networks"
-Go to your Launcher, and open LbsTestMode again
-Click "Delete GPS" Data
-Exit the App, and close it with a task killer.
-Open it again, and click "Get Position Test"
-It might take a while for something to show up....but it eventually will. Let it run for about ten minutes straight.
-Close the App again, and you should be good!
Upon Position test....I got:
Accuracy: 41 (meters)
Number of Satellites (INDOORS!): 9
Speed: (m/s)

Just came across this when I was freaking out about my crappy GPS lock. Just got this phone to use on Mobilicity and was concerned there was some T-Mo setting that needed to be changed. Anywho, this works wickedly. Thanks a lot.

I'm aware of the GPS issues with the Samsung Galaxy S. I have the Samsung Galaxy S 4G and I'm wondering if anyone with this phone is experiencing difficulties getting GPS to lock in.
Within approximately 10 minutes, I can see in the GPS Test app about 3 satellites in view. Given enough time, it picks up a few more and eventually locks in.
I've read about the Super GPS fix and the hardware fix but I'm not sure if it would be wise to try it on this phone since the fix was meant for a different model and I don't see any mention of anyone trying it on the GS4G:

I have the gs4g and tried GPS AIDs with some improvement . At the most I would lock onto 7 satellites when it felt like working. I lifted the contact as indicated in the thread above. I then deleted the old GPS data. Then in GPS AID I regenerated the DATA and rebooted. Now i get 12 locks on satellites all with green signal status. Very please. Google maps Locks on with in seconds....

I think I spoke too soon. I tried this in Calgary and it was great. I'm now in Toronto and I haven't gotten a lock since I got here on Monday. Tried messing around with the settings again, but just won't lock on. Also tried auto config to grab SUPL info from my provider, but that didn't work either. Still working on it.
Start over and flash krylon deoxed with odin, cwm, bionix. This resolved my 10-15m lock times completely. Now I get a lock in seconds.

Amazing!
I tried this and got accuracy within 3 meters off 10 satellites. Before, it was about 80 meters. Just awesome.
You don't need launcher pro to get into LbsTestMode. In your phone's dialer, just type *#*#3214789650*#*# and it'll go into it.
As for what you suggested about going in and messing with the settings, the first lock takes forever because you've wiped out all the ephemeris data by deleting. It starts looking for satellites for your first lock which takes a while with no ephemeris data. Once it gets a lock, it starts downloading ephemeris data and subsequent locks are significantly faster because your phone now knows where the satellites are.
AGPS helps reduce the lock time a bit (by using mobile location and the SUPL server), but not by a huge amount. The largest reduction in time is due to the fact that you have updated ephemeris data. If your ephemeris data is outdated, your lock times will go up again.
If you don't believe me, try this: get your lock. Then shut off your GPS by using the pull down panel. Leave it off for at least 24-36 hours. Then try to get a lock again. It's going to take a long time again...
I've been tinkering with the GPS on this phone for a while now as well as my GF's Vibrant. There's no doubt in my mind that the SGS4G is improved over the Vibrant, but it's still not great.
I've also pulled apart both of these phones and done the hardware fix by bending the little tab every so slightly. Made a significant difference on the Vibrant which was having a problem maintaining locks and the GPS signal was bouncing all over. No noticeable difference on my phone.
My only conclusion is that the antenna on these things are poorly designed and just take a long time to get an initial lock. Once locked, it's pretty solid. Other phone manufacturers have GPS that work better though. No reason why Samsung couldn't do better.

Strange GPS issue

My Nexus 5 running 4.4.4 has starting acting strangely this morning with anything to do with location services.
Only started this morning when I went to show a colleague the Waze app. Said my current location is Haworth, Yorkshire!?! I am actually at Watford Junction station Hertfordshire! Lol!
Even tried Google Now navigation and said 212 miles to home!!! So it remembers where I live?
I have never been to Haworth, let alone being there now.
Have tried rebooting phone, indoors and outdoors, turning off all location services and it is still showing wrong location?
Anyone have any ideas?

Have you tried in a completely different location, or go into Location settings and set it to Device only to force GPS and wait for a fix. It might just be your phone is defaulting to Wi-Fi location, and a new access point has appeared near to you that used to be in North Yorkshire!

Tried device GPS only, and not GPS/data/wifi, and picking me up fine. GPS on its own, mobile network on its own, both work fine, but not the 2 together?
It is very strange as it only started happening this week and only when I go into the mess/break room at Watford Junction station. And always Haworth! But now, as soon as I step out of the door, it sorts itself out within a minute or 2. But it does happens every time I go into there now! There is a wifi signal at work, but cannot pick it up in the mess room, so can't be that interfering?
It is not a biggy as not as if I need a satnav to drive my train! lol! And to see the weather, I look out of the door (no windows!)

weak GPS signal problem?

Is anyone experiencing problem with their GPS signal? Mine would lose the GPS lock constantly. Thanks.
Working fine on my end. Out and back, my drive was 5 hours total.

No, no problems at all. And I used the GPS allot.

Make sure yours is set to High accuracy. Mine was not after set up. I had to change.

Even in high accuracy, I lose the gps signal frequently. Sigh
Do you have a case on your phone?
I just got my cases in and have noticed weaker gps performance since putting the phone in a case.
I've been having major GPS problems. Going for a run and expecting the phone to track my route and calculate my speed accurately shouldn't be too much to ask in late 2016. But my phone constantly loses the GPS signal (this was never a problem with my previous phone in the same location) and even when it doesn't, it can't figure out where I am. My run traces often show me two streets over in addition to thinking I'm jumping back and forth across a busy 5-lane road every 5 seconds or so. I run 6 miles and the phone thinks I've gone 8.25. Not useful for training for events.
Even if you don't want to use the phone to track exercise, there's another reason the bad GPS is annoying. It makes it impossible to take advantage of the feature allowing you to unlock the phone without using your fingerprint or pin based on your location. I have my phone set to be unlocked at home, but the phone apparently can't tell when I'm at home, making this setting completely useless.
As to GPS issues while driving, I haven't noticed them, but I've not used the phone for navigating either.
Would like to mention that while I have a case on it, it is quite light and doesn't seem like it should interfere so badly with the GPS. Will try checking the accuracy without the case and will update if this resolves the issues. Also, I have tried tinkering with the GPS accuracy settings but even selecting all the options to optimize accuracy has not worked for me.
The only thing you can do to test the case theory is to use the phone without that case. That said, it is possible you have a defective phone. I have read many articles about poor GPS being caused by a loose, internal connection. You might want to take your phone to a repair facility and have them check it out.
I have a US996 and, so far, GPS is nice.

how can you change it to high?
No issues on my end yet, I use it navigating on a daily basis (racking up Waze points basically) and walking around, can't think of maybe one time it lost GPS driving and that was only briefly.
Mine was misbehaving horribly. I tried using google maps to see if it was something to do with Navigon, (my normal gps app) and somehow it seems like just running maps fixed it. It has been working great with Navigon now.
Go figure.
GPS on my Sprint version has worked great in all 3 options since day 1

On my rooted VS995 software version VS99513A on notsostock kernel v1.2 the GPS seemed to never be able to locate my current location. When I used it before without root it picked up quickly. Am going to try nostock kernek v1.1 the updated version and see if I get a difference. Plus now am running magisk instead of supersu so will see if that makes a difference.
It's possible that the a-gps data is corrupt. I'm not sure how you'd go about clearing that. There must be a cache file associated with gps daemon.
Try installing this:
https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2
And when GPS isn't working, run the app and see if it's receiving/decoding any satellites at all (bar lengths indicate strength, colour indicates successfully received all ephemeris data from satellite and therefore has lock - it can take a while without a-gps).

P.s. I found that taking the back off my phone improves Wi-Fi. Metal blocks radio signals.
If you have low or no signals in a specific location, try popping the back of the phone and seeing if the signals become useable.

Sorry to bring up an old thread. I just bought a used LG V20 (at&t version, H910) on Craigslist the other day, and have had GPS issues that made me highly annoyed like I bought a lemon phone, and was getting ready to call LG Support, and pay a lot of money for repairs.
Happily, I did discover a trivial solution that I haven't really seen, so I thought I'd share it.
After I purchased the phone, I factory reset it. It seemed like the device would be able to triangulate a position, but it would be unreliable, move around, and the accuracy would be highly variable. (observed in Google Maps and Waze). These symptoms seem to be consistent with other people's experiences. The useful and highly recommended "GPS Status" and "GPS Test" apps, that normally show visible satellites were showing ZERO satellites. As suggested in various places, I used "GPS Status" to re-download the A-GPS databases, set "sensor filtering" to medium. Still, zero satellites, but a semi-functional GPS, which is confusing. I found the hidden menu code for the H910 (*#546368#*910#), and SAAT->"Manual Test"->"GPS/BT/Wifi test" and ran the hardware-level GPS diagnostics. I was getting signals of 0.0 db for GPS and GLO satellites, kind of suggesting the GPS hardware was faulty, and made me even less optimistic/more annoyed.
I was basically convinced GPS on my phone was kaput, and would need to be serviced, until I discovered ........
Rebooting the phone solved all of the GPS problems, and made GPS and GNO satellites visible and now GPS is 100% functional. It seems that since I initially factory reset the phone and did my normal installation, I never did a simple reboot. Since I haven't seen that kind of obvious solution on any of the forums, I thought it would be useful to report. I'm cautiously optimistic that was my only problem ......
good luck
=mxasf=
Bought a used one and having problems: it'll fix on several satellites but it's usually unable to acquire the specific location (latitude and longitude). Depending on the program, it will say "waiting for GPS fix" in osmtracker or "looking for GPS location" within 'GPS Status' (the app).
When it does get a 'Lock' (a specific location), its accuracy is 200-300m off. :/
I tried some of the other common tips and tricks:
I've downloaded new A-GPS data (using the 'GPS Status' app); tried using the GPS without my case on; doing a simple reboot, none of them work.
After more searching, I found this guide: https://imgur.com/a/VxeaU which recommends to place copper tape on the GPS antennas of your phone.
i have 2 V20's.. the one i bought back for myself is 12/2016 and another one is another batch 3/2017 for my wife..
What i'll found is the earlier one ( 12/2016 ) have the following issue :
- overheat
- kaput gps
- screen burn
While the one i bought for my wife ( 3/2017 ) doesn't even have the following issue above.. Furthermore, the screen also different.. my wife V20's tend to have a more saturated color, brighter screen and doesn't overheat as much as mine..
My conclusion is, only those with earlier batch of production have all this defect.. and to those who own it ( including me ).. i guess, we're unlucky!
i'll use my wife V20's as gps since mine V20 is good for nothing when GPS is a needs.... if she's not around, i'm totally doomed !
-----
if you guys wonder, there was no different in camera.... unlike G6 ( pheww~ )
both my and my wife V20's produce the same images quality..

I followed that guide (credit https://www.reddit.com/r/lgv20/comments/7fx2gz/becareful_buying_the_top_plastic_bezel_of_the_v20/)
and bought copper tape (https://www.amazon.com/Copper-Conductive-Adhesive-1inch-12yards/dp/B018RDZ3HG) off amazon.
For me and my VS995; there were metal contacts (see picture 1 of the imgur album) and the metal contacts were silver, not gold.
Nonetheless, I put some copper tape only on the first contact as shown in picture 1 and my signal improved dramatically. The lowest accuracy that I can get (lower is better) now is about 8m and it has been hovering around 15m; and still takes a few seconds to
This is compared to my s5, where I could get an accuracy as low as 4-5m and usually hovers around 8-10m and could obtain my location within 10 seconds after turning on GPS.
