Following on from THIS thread, I thought it would be worthwhile to gather results to see the extent of the problem and to see if there's any pattern with regards manafacture date/place etc.
The Issue
GPS position is extremely erratic and despite showing good precision of 4-5 metres, the position moves around by up to 100s of metres, making it near useless for most applications.
Resolutions Attempted
Clear AGPS data doesn't make a difference to everyone
Use Airplane mode or Turn off Google location service. - Seems to reduce the problem but does not completely solve it.
The Survey
Install from the Play Store - GPS Status & Toolbox and My Tracks
Open Location in the phone settings - Ensure all location options are enabled
Turn On Airplane Mode
In GPS Status & Toolbox - Menu>Tools>Manage A-GPS state>Reset
Open My Tracks, wait a couple of minutes to obtain a good fix, Menu>Record Track
There are 3 views in My Track; Map, Time & Elevation. You can select these by tapping the screen and selecting the left or right arrows.
Change to time view and after 15 minutes, Menu>Stop recording & save track
Turn off Airplane mode
Repeat steps 5 to 7
Post screenshots of your track results
Include 1st 5 digits of your serial, phone colour & software version

Grey Model - Serial HT248 - Software is 1.29.401.11 - Airplane Mode On (Serial is from memory, will check this-evening)
Absolutely superb results with no movement whatsoever
Note: I opened the track after recording and turning off Airplane mode so I could see the map in the background.
Grey Model - Serial HT248 - Software is 1.29.401.11 - Airplane Mode Off (Serial is from memory, will check this-evening)
Not quite as good as with Airplane On but still very good and more than acceptable. In fact tthe only movement was in the 1st minute of recording so I may have just started a little too soon.
Grey Model - Serial SH24K - Software is 1.29.401.11 - Airplane Mode On (Serial is from memory, will check this-evening)
Definitely worse than the previous phone but just about useable for coarse navigation, although the elevation seems to come off much worse.
Grey Model - Serial SH24K - Software is 1.29.401.11 - Airplane Mode Off (Serial is from memory, will check this-evening)
The pictures speak for themselves, Absolutely horrendous and completely unusable. This phone is going back for an exchange.
Update: I've spoken with Phones4U (seller of faulty device) and they've agreed to exchange it. I'll post results for that one when it arrives in the next couple of days.
Hi guys,
Im having the same erratic behaviour? Is this hardware related or software related? Im wondering is this due to absence of signal filtering? So its plotting raw data directly
Edit:
Nope, its hardware related and i don't think signal filtering is an issue.
Hi, this is my test. I think the GPS is working properly. What would you say about?
serial 26 China
I agree. I think HTC One X has an unstable GPS .
I am not sure if it is hardware or software (i.e. OS)
I am using ATT HTC One X with updated firmware.
And this is speaking from real world usage. Which is after all what is important to us.
I used CoPilot and Google maps . Both experienced very unstable GPS signals i.e. every 30 mins there will be a drop. I had this tested twice on QEW high way, i.e. from Toronto - Niagara Falls. So it was clear sky
I had back-forth trips for 5 times on QEW. 2 out of which I used HTC-one x . the other 3 trips I used Galaxy Nexus.
For the trips using HOX, the GPS signal dropped quite often, every 30 mins or so and it takes long time to relock position, if anything at all.
While using GNex, there is no drop of GPS signal for the same route.
Any folks here proved it to be an OS issue or Hardware?
Thanks for any light on this.
Navigon works perfect for me, it always brings me to my destination. :laugh:
No problem with GPS I ques, it brings me to the door.
Probably a hardware fault with your machine, return it for warrantee.
No need to open another 'yes no yes no yes no yes no' thread, only HTC can help you with the hardware fault, not XDA. :cyclops:
Some will agree with you while others don't, so simple !!!
Hello, here attached are my stats with Airplane Mode Off, Serial - SH27J and Software - 2.17.401.2, white model. What do you think, is everything ok?
Mine is pants ... Utterly disgusted with HTC I've held off til September to give HTC a chance to resolve it, bought phone ... GPS all over the place AND no bl00dy Bluetooth voice dialing !
On top of that ... What's the point of taking it back for exchange : they nearly all seem to be like it : we got 2 me and the wife and the gps is the same, I can't tell her, she'll go ape, she's just spent 2 weeks getting it how she likes it
Miffed , very miffed

Very interesting Gabrielvl ... worth knowing if the fault comes back after the warranty runs out:good:
Hallo,
I'm on a Vodafone brandet hox. I had the same GPS-fault. I updated my phone to buildnumber 2.17.161.4 yesterday. I performed a factory-reset before i started the update and after the update and now the GPS works fine. No signallost or positionhopping. It seams the bug is fixed and it is a softwareproblem not a hardwareproblem.

Thanks, I have succesfully fixed my Wifi already using this method so if this also fixes my GPS I will be a happy man!
Will try and let you know.
If you're locked into as many as ten satellites is there any reason to have erratic GPS performance?
I got a refurbished S3 from Sprint and the GPS is a freaking mess. I can be standing perfectly still and the map starts moving around erratically, sometimes even straight backwards. Other times I'll be driving and it will show me on a totally different street or moving in a totally wrong direction. Sometimes this is going on when I'm locked into as many as ten satellites.
Shouldn't that be enough to get a good fix? Does this suggest that the GPS receiver is working well but there is a software problem? Or is this a hardware problem that can't be fixed?
I reset/downloaded agps data with GPS Status, I've tried TopNTP and I've tightened every visible screw. Nothing has helped. I also can't get a fix indoors like I used to be able to with my original S3.
Any suggestions on other things I can try to make my GPS work or is this a hardware problem that can't be fixed?
This is the fourth or fifth refurbished Android phone I've received from Sprint over the years and not a single one has worked right. It's like they don't ever really address the reported problem. They just factory reset the phone, give it a cosmetic facelift and then ship it back out without any testing.

I'm totally stock 4.3, just rooted. I rooted it pretty soon after I got it so I don't remember if it was like this right off the bat. I believe it was.
Weird thing is that today I tried turning of Google location services and that seemed to help a lot. It doesn't seem to be getting a lock while indoors but when I'm driving around I'm not getting the erratic map behavior I had before. No idea if it will work for long, there have been a few other times when I thought I fixed the problem and it came right back.
I know on my previous phone I had Google location services on and it worked like a charm. Anyone have an idea why turning location services off helps and what I can do to make GPS work right with location services off?
Any real downside to keeping location services off?
I've always kept it on. But if your Stock rooted, and have that big an issue with GPS. I would almost be inclined to say it's a hardware issue. You could always Nand, and flash a coherent Rom. Just to see if it resolves the issue.
TEAM MiK MikROMs Since 3/13/11
After driving extensively with Google location services turned off I did not experience any more erratic behavior. Problem solved but I'd like to have location services on.
Tonight I turned location services back on and it still seems to be working fine with no erratic behavior. I haven't given this as thorough of a test but I'm optimistic.
I have no idea why turning location services off fixed things but if anyone comes across this thread looking for a solution to GPS problems try turning Google location services off and see if that helps. It looks to have done the trick for me.
after a loooot of search on the internet and after reading all the older posts here i am desperate and i am opening here a thread. Thats my last hope that someone found a solution to this issue.
So 6 months ago i bought a nexus 7 2013 wifi for a car project. i wanted to use it as multimedia and navigation system. After i modified my car (see pic. / contact me in case of interesst or advices)
https://postimg.org/image/exyp7da37/
everything was nice i was happy with the result. The problem starts when i wanted to use the navigation...
The device cant find a satelite, searching for gps signal is the only message i see. 9/10 the gps cant find satelite. One or two times it found the signal after one hour or more..
My thoughts:
1. The case is causing this issues... the tablet charges wireless and is kept in place with magnets so i can remove it in a second.
I am trying with the "naked" tablet outside with directly sky view... no change.
2. The backcover is modified with 2 small metal plates in order to get magnetizied with the magnets installed in the car dush.
i tried an other backcover.. no change.
3. I tought it is a software issue.... i was using Cyanogenmod 13 with elemental X... installed the original software / Android 6. Without any other installations only GPS Status... still no signal.. I installed android 5.0.1 ... still no signal.
4. i used various of settings changes and apps ( GPS FIX, GPS Doctor, GPS Status) ... the gps android settings are the the most accurate level. Still no change..
created the data/gps/ folder with the permissions rwxrwxr-x. Still no change.
After all that and after reading that there are many people out there with the same problem i thought thats a hardware issue.
5. Thats why i bought an other one (used)... before buying it i made sure that the tablet will find a satelite in GPS Status... i went to the sellers house.. and it did (with wifi off). I went back home i tried again and it did... i was so happy.. i wiped my storage flashed CM13 with ElementalX again ... i opened the Nav App (Sygic)... Everything worked like a charm... i was so happy i finally have gps in my car. I visited a friend stayed there 5 hours went back home... Navi still works.
I took the tablet in my home and wanted to make a restart for some reason... After restarting , tablets gps was dead again... and still looking for a solution..
i am 100% it is a software issue. in case there is someone out there with a solution i would really appreciate it.
I'm kinda on the same boat.
My trusty Nexus 7 2013, that has been through a lot of display changes due to my clumsiness. Few days ago it decided to kick the GPS boat for reasons.
It used to work just fine, without any software tricks or anything. Used to work beautifully without wi-fi (even though I tethered from my phone, many times I travelled to places without connection) with a 8-10m precision.
Now it's spotty, taking from 2 to 280 seconds for the first fix, and precision floats between 10 and 150m (which is unbearable).
Using GPS Status & Toolbox, I can see the A-GPS does it part guiding the tablet on where are the sattelites at (I see around 22 sattelites), however the tablet has a real hard time connecting to them, most of the time staying at a solid 0 connections. My phone (Moto G5 Plus) connects within' seconds to the sattelites with pinpoint precision.
When the tablets manages to fix, it only connects to a couple (5 or 8 out of 22) sattelites, thus not so precise.
I am guessing the heat might have damaged something, but I'm not also 100% sure it ain't a software issue. I flashed the sole GPS fix, but it didn't help at all. I tried every software trick on the book, but nothing. I flashed several ROMs but it didn't make even a dent.
It seemingly gets better if I keep it connected for a good while. I tried letting it overnight with the GPS connected, and it worked fine the day after at any time (between 5 and 20m precision). However it was dead again the next day.
I couldn't find anything regarding a GPS antenna for this device, it's almost like it doesn't have one... I fiddled with the Wi-Fi antenna, which has 3 pins (one I guess is for bluetooth?), but it didn't help with GPS. Bluetooth (I use an OBD2 scanner that sends too many data per second, and I still can play music through bluetooth just fine) and Wi-Fi (Speeds and latency are optimal) are great.
I can't help but think this device doesn't have a GPS antenna, and whatever it uses for an antenna has failed or is now faulty.
Have you ever managed fixing yours?
Just recently over the last couple months, I have been having a problem with getting a good gps signal in programs such as Waze and Google maps. I have done all kinds of searches and many mention to go into settings and in location settings, turn on High Accuracy. That option is bo longer available and not sure if it was eliminated in Pie. I have been doing all the latest updates and believe I am current. The only thing I have been able to find is to go into settings, then Biometrics, and there I found location. The only choices under Improve Accuracy is to turn on Wifi scanning and Bluetooth scanning which I have done. There no longer is a choice of High Accuracy and the ability to turn GPS on or off like I had in previous phones and previous versions of Android. I have even tried turning on High Performance under Battery Power settings and turned off any choices to optimize battery or disable apps. I ended up downloading 2 different GPS apps from Store, GPS Status and GPS Fix/Optimizer. I will normally use Waze or Google maps through Android Auto. I can tell when there is a problem when the position indicator keeps bouncing all over the place in Waze and cant find exactly where I am. When that happens, I will check on GPS Status and it always shows that it is having a problem acquiring the satellite signals. I will then open up GPS Fix/Optimizer and on the home screen, there is a button that will say Service Off. I press it and it will then read Service On. Switching back to GPS Status will now show that it is starting to acquire multiple satellite signals. When I switch back to Waze, now it is able to show my exact location and begins to work properly.
This is driving me nuts. I never had this problem on any other of multiple different phones or Android versions. I can get GPS working but have to jump through all these hoops each time and it sucks. So what other steps can I do to be able to fire up Waze and have it find me right away?
It's not just an Android Auto thing, it happens with GPS in general. There have been many posts about it over on Reddit in the Note 8 Forum dating back to March. The best fix is to just toggle location whenever you notice that GPS isn't working.
The scary thing is not only has Samsung not even acknowledged there is an issue, newer phones are also starting to have the problem. Just saw people complaining about the same thing in a S20 forum. Just like our issues, they started after an update.

Did you ever find a fix for this problem ? I am dealing with this too and have been for a while. GPS when using as a phone is no issues at all but, once you connect Android Auto, it's a mess. Very hit or miss and even if I hit where it works, it will drift off and require me to unplug/re-plugin my Note 8..
I posted to a few other places on this issue, nothing has solidly fixed this. Otherwise my note 8 works fine, so I no reason right now to upgrade, till the phone I want drops a little in price.

Anyone else figure this problem out ?
I still havent found a fix. Here is another thread I started on the main Galaxy Note 8 that produced a lot more discussion but sadly, no fix yet.
https://forum.xda-developers.com/galaxy-note-8/help/recent-gps-problems-t4058849
For me at least, it seems like it may be an issue between Android Auto and my Chevrolet. Still not entirely convinced but folks over at Android Auto claim that there is a communication problem with Android Auto trying to communicate with the internal gps on my truck. Supposedly even though I dont have traditional on board navigation, there is still gps communications going on. I believe that with Chevy, it is the onstar system. Android Auto is programmed to utilize vehicle gps because it is supposed to be more accurate. Unfortunately, if that is the case, and there is constant communication error between the Note 8 and vehicle, the result is that the apps in AA like Waze and Google maps continually have location errors. I inquired why AA couldnt just allow users to utilize the phone GPS as an option and was again told that a vehicle gps would be way more accurate so that option isnt available. When unplugging usb from vehicle, it defaults to the phone GPS and begins working again almost immediately. So is the problem with AA programming or communication problems with my Chevy truck? Who knows. Sometimes they communicate just fine from the get go but other times, not so much. I just wish the problem could be fixed. I would be leaning towards AA programming as this does not just happen with Chevy vehicles but AA just passes the buck.

Yep, saw that thread as well and the one on Android Auto's site, I even replied to it. Wishing there was a solid fix here but, no... I have a Lexus LS that I added on a 3rd party Android auto device on. I had this same issue when I had a 2019 Ford with Android Auto as a rental. I figured 6 months later (I just put AA in my car about 2 weeks ago) it would be resolved by now.
Not 100% sure it is the GPS car thing you were told, as other phones plug into Android auto and have a seamless experience if this was the case, all phones would have this issue. We are using the same software. So why is the Note 8 different ? Well, I hear this effects other Samsung phones but, none as bad as the Note 8. Newer Android 10 even Samsung phones do not report this issue, as far as I have heard.
Oh, well the quest goes on... If you find something, please drop me a line....and thanks !
"Me too" - Driving me crazy. Toggling Location services off and on sometimes helps, but not always. I'll be moving, and the map doesn't reflect any movement.

Toggling when driving is not a good idea, Normally unplugging and plugging back in works just as well. Funny for the last week, it was working fine (get lost when in a lot of trees and sometimes not recover but, on the highway it was perfect), till this morning and it was a mess.
There was an update for the Note 8 on Verizon a week ago, I need to double check all the power saving features and make sure they are fully disabled...
I had also started a thread on the Google Android Auto community back in May where the developers monitor posts. Just recently (about a week ago) it seems they are acknowledging that there may be a problem and posted they were going to send out emails to several that were affected by this. They gave directions on how to forward a bug report to them when the problem showed up. I was one that received the bug report email. I have since submitted 2 bug reports to them but have not received any kind of reply. Hopefully I hear back sometime soon and they are able to identify exactly what the problem is. If I do, I will post their response...
This could be a one off device issue, But over the past 2 weeks ive noticed my GPS has become unusable.
Downloaded and Used a 3rd Party App called "GPS Test" to look into it in more detail.
Would appear the GPS would work but very weak and limited results after a few seconds results would dwindle down and show no signals avalible.
Reboot the device then all of a sudden the GPS Test would show results, results would appear for around 20-30 seconds then numbers would start to drop to 0.
Other time i am able to reboot the device, Open up GPS Test and it would get a Fix, I would start driving and it would loose the Fix and Google maps would say searching for GPS.
Other times i have rebooted the device and its located a GPS Fix, opened up Maps and drove home without any issues.
Other times i will drive home and it will work then stop working then start working jumping in between 5 - 10 miles in between it reconnecting.
I have factory rest the device, Made no difference.
Just downloaded the latest Formware files and flashed using Odin so its clean and has nothing installed and still experiancing the same issue.
Device has not been rooted.
Unsure what else i can do, I am starting to think its a hardware issue. (Just dont understand why it would work for a few seconds after reboot before failing)
Raised issue with Samsung and waiting for a Door Stop Repair (Slots are limited so still waiting on mine)
Unsure if anyone else has had GPS Hardware issues.
Also open to suggestions
You are probably correct about hardware issue. Mine has some issues with the compass needing frequent calibration. Not bad enough to bother replacing, but clearly not to spec. It happens.
Sounds like bad hardware or failing internal connection.
Try clearing data/cache... otherwise most likely hardware.
A failed chipset, contacts, trace or solder joint.
This was a common issue on the S4; the GPS antenna contacts would fail over time; poor design.
Not sure how it's implemented on the Note mobo. Either way the phone will need to be opened up... sorry.
