GPS not working!!

Until few days back GPS was working like a charm.
Today I performed an upgrade of Google Maps to 5.9.
And GPS doesn't work!!! Searching and searching, not able to fix satellites!! Outside, sunny day...
Uninstalled upgrade, rebooted phone, reinstalled upgrade....
GPS doesn't work! On old and new version.
Any ideas what can cause that? Anybody experienced similar problems??!! What a disaster!

only in Google Maps or also in other apps (car dashboard etc)?

When I use Google search it doesn't work either.
I don't use apps with location but just checked with WeatherBug and apparently it doesn't work either!

GPS working fine here on .368 update using Maps 5.9

This is crazy but after second reboot it works again.
It's so strange!

If you don't use GPS that often, a fix can take a long while. I'd suggest a tool like GPS Test to see if it's picking up a signal and what the quality is like.

Those bars will tell you about the GPS signal. If GPS would not be working at all the bars would be completely flat. If you get some bars, it should be a matter of time.

Well thanks!!

I guess nobody needs 2 GPS test apps, but if you do then i can recommend GPS status.

[Q] Problematic GPS

My GPS has been problematic lately. Currently I have an AT&T version that I converted over to GPE (4.4.4 with GPE kernel 3.4.0-gb1b6fb1 [email protected]#1)
Lately I haven't been able to use my GPS apps. So, I started going through the motion of refreshing the A-GPS data.
When I downloaded GPS Toolbox from the Play Store, I noticed that it was seeing GPS satellites but it couldn't lock on ANY of them -- I ran it for roughly a few hours but inside and outside. The number of satellites it's seeing is always roughly 15+. My location settings have High Accuracy enabled. (Which I believe is the only thing I need to have checked, right?)
I think it has something to do with the modem but I don't know how to troubleshoot through a process in order to get a definitive answer.
Could someone offer some suggestions on what to do?

I just finally gave up with it, pulled my dusty old Garmin GPS from my closet lol

I have the same problem. Can see 21 sattelites but no lock. I have this with different roms.

Any success here :?

Gps issues

Ok so this started today, gps is constantly losing lock, then gaining it back. Happening in Google maps, Waze and Pokemon go. I booted up gps status, and it's constantly going from double digit satellite lock to 0, then jumping back to double again. Phone wasn't dropped or anything. Is this thing defective now?

Were they ever resolved with a software update?

No. But I recently found out that if I turn off high accuracy and instead use device only mode, it works a lot more consistently. Received my RMA Pixel today, will report back if anything changed.

Any luck? im having issues myself.

I don't typically use GPS for long periods of time. Mostly just in an app that's trying to get my location once instead of continually following my location like navigation does and in those cases I have not had any issues.
In the cause of actual navigation, in the 5 weeks I've had my Pixel 2 XL I've used navigation maybe a total of 2 hours. It's not a very big sample size but so far I haven't had any loss of satellite lock.

Try the following:
- Close all apps that use location.
- Go to Location settings, switch to 'device only'.
- Then turn off location/GPS completely.
- After that, open Google Maps. It will ask you to turn on location services. Click OK on both dialog boxes.
Following this procedure I could resolve my problems with GPS on 4 different Android phones.

So looks like I'm not the only one with this problem. I also realized that turning off high accuracy fixes the issue. However, I strongly believe that with high accuracy, it makes use of cell tower information for faster location lock.. and if your cell reception is not good, it screws up the device-only GPS signal as well.
The reason why I say this is because when I was on vacation for the past week, I drove long distances and was on roaming (drove across Malaysia to Thailand), thus having poor reception. That is when I had GPS issues. In Singapore where I reside, the cell reception is much better and I do not have such issues.
Now setting the GPS setting to device-only isn't a permanent solution. Apps like FB needs it to know where you are.
I think Google needs to fix this. Has anyone logged this yet?

I haven't had the issue again since 8.1, so I'm hoping it's fixed.

Unfortunately not

Any update on this? I'm having the exactly same issue. Pixel 2 XL.

I finally resolved this issue by changing my carrier. Any other attempt to solve this failed in the long run.
I realized my carrier or sim-card was the culprit when I once enabled airplane mode while navigating - suddenly I got an instant GPS lock that stayed.

Changing carrier sounds a bit extreme but wouldn't everyone on that carrier have that issue? Which carrier was it?

Yes I know, maybe it was my sim-card which I have had for years. It does not make much sense to me anyways. It was "Drei"/"3", a carrier in Austria.
I really tried lots of settings and combinations of settings and at some point I figured out the following:
When I still had that carrier, GPS worked flawlessly only when I
- enabled flight mode OR
- when turning off mobile data OR
- when set to '2G only' mobile data.
So maybe if you have that issue you can try these settings to check if it's similar to my issue.
Ever since I changed carrier (and sim-card ofc), my GPS problems went away.

GPS problems only in my country?!

I'm constantly losing the GPS signal during navigation.
I've already replaced the phone two times through warranty and the mainboard got replaced each time.
The last time was just one month ago.
The problem always remained though.
The last days I could observe that this issue seems to be caused by my provider. Is this possible?
I have travelled through 4 bordering countries the last few days. The GPS worked great.
As soon as I passed the border to my country and the network switched to my home provider the GPS signal got lost shortly after and lost signal continuously frequently.
We were joking a lot about it because it happened every single time.
Is it possible that my provider's network can somehow cause theaw GPS drop outs?
Can I fix?
I'm happy about any help!
Thanks

I guess I am alone with that

Try using this app to clear or update assistance data (AGPS).
I have also found that a GPS connection is made much faster when the data is turned on.

Thank you, but unfortunately this doesn't help. I've already tried it many times.
I only have the problem in my country or rather with my provider.
I should try a friend's SIM to confirm it.

The problem really seems to be related to my mobile connection.
As soon as I turn on the airplane mode the GPS works perfectly.
Anyone got an idea what the issue may be?

Have you tried to set LTE/4G to 3G and tested?
Do you use Custom Rom?

Currently I'm using CypherOS 4.2, because I was hoping that the GPS will work better.
I am using 3G because my plan doesn't include LTE.

Do You urgendly need GPS With 3G or is only GPS enough? Have you Tried only GPS?

I usually don't have offline maps and I'd like to be connected while navigating or be able to receive messages.
Besides that it's a fault that shouldn't happen with the phone. Using GPS should work without limitation.

I've being using Navigon Europe for the last 6 years. First in LG-P880 and last 2 years with G4 H815. Sometimes, but only sometimes, maybe weather, high buildings, I don't know.... I have problems with GPS.
I've use it in Poland, Germany, The Netherlands, Belgium, France, Spain, Portugal, Italy and Luxembourg.
My location is set for "High Accuracy" (GPS and Networks), no matter if DATA is ON or not.
Of course that when DATA is ON my location is detected almost instantly.
But if you see that network is messing with the GPS, try to limit network access on your network settings. Maybe it works.

Yes GPS should work without limitation, but if Your provider has messed something up,its his fault.
And like You said it works in other countrys so its not Your device.

Or GPS is fine but the software not... I mean, the apk might not be the best.
How can a provider mess with the GPS? The signal are where they are, not possible to shake, move them, hide them...
Maybe the lack of signal from the provider might counts concerning the maps. If the data needed to navigate is downloaded and how fast.
Also, with no data, how it's possible to use GPS without offline maps??

Use GPStest from play store https://play.google.com/store/apps/details?id=com.chartcross.gpstest and make sure you are getting enough satellites. Also with that app you can reset and retrieve the a-gps data.
Just a thought

My GPS is fine!
Stop answering my posts as if I have an issue.
Thank you

It's definitely not a faulty device since the motherboard got replaced already two times.
It's somehow an incompatibility between my provider's network and my phone's GPS.
I am using GPS test since many years and love it. It doesn't help in this case though. The GPS status there also freezes when the GPS stops working.
To answer the question how I can use navigation without data:
Google Maps caches the maps so I can use it also offline.

Install a navigation apk like "Navigon" or "CoPilot", something like that.

I know these apps but I don't want to turn off data when using GPS.
I was hoping that someone is familiar to this problem and knows a fix.

And you don't have to turn OFF data while using them.
And once again, maybe there's nothing wrong with your device or carrier, maybe the app that you're using, or how accurate and updated are the maps of a specific country.
In Portugal, there are places where the GPS goes crazy, just because of the maps.
In Poland, sometimes I'm driving on the grass. The roads where deviated but the map was not updated. So, I know that is a problem of the map because I know how the roads where before and now.
Someone who don't will say that the GPS is crazy...
BTW, in The Netherlands, 6 years ago, I use to drive over the water most part of the time :silly:

Hi,
have you found a solution to this?
I notice very similar issues now and then during road navigation, gmaps (and others previously). GPS signal repeatedly disconnects and then reconnects after a while, and velocity reading becomes 0 or odd.
I thought it was overheating, but a carrier incompatibility issue seems plausible,.

Hi!
No, unfortunately I didn't find a solution. Replacing the motherboard didn't help either. I have a new phone now and don't have the problem anymore.

GPS lag during navigation

Hi guys,
During the navigation on Google Maps, my displayed position is about 100mt or few seconds back from my real position. I noticed the problem increase when I turn.
I have a S20 Ultra snapdragon version. I used Maps for almost a year without any issue.
I restarted the phone. Cleared Google Maps cache and data. Reset the compass. Reset the GPS and downloaded the new data thru GPS Status app.
What else can I do?
I'm really getting lost.. in all the ways.
Do you think is a software or hardware issue?
Any help is really appreciated.
Many thanks

Hey David Im having the same issues. When im running using Strava the location frequently bounces around and GPS is practically unusable.

I just spoken with Samsung, after a GPS test they said me that it's an app issue and that my GPS is working fine. I'm not sure about that..
I hope someone already solved this problem.

Nothing. I downloaded and tested another app.. exactly the same problem.. must be a samsung problem. I hope a software problem that can be fixed with an update.

Sometimes it happens to work, i would say 1/5 times. I just installed the may patch hopefully that fixes some things.
