Weird thing is that my Nokia 8 is on the list and when checking GPS Test (this one) I get GPS, GLONASS, and even some BeiDou pings but no Galileo.
EDIT: After 18 minutes, 4 have appeared all at once. Either I don't know how these systems work or the Galileo system doesn't have great coverage for my area.
GNSS ID: 1, 7, 26, 31.
EDIT 2: Had a walk outside to get some direct LOS. Suddenly 8 appeared. Seems the Galileo satellites have more difficulty penetrating my roof compared to GLONASS and GPS. Went back inside, seems to have settled to 7 now, 3-4 of which are being used.
GPS know their own accuracy and can report it. You can use an app like GPS Test and it'll show you what's the accuracy of the position currently reported.

Do you remember hearing about the iphone 4 antenna issue? The XZ1 seems to have the opposite problem - the GPS antenna performance appears marginal until you have some fingers, or the base of your hand, along the left side of the phone.
Someone here on reddit suggested "squeezing" on it around the SIM slot some time back, but I've been doing some experimenting over the past month and it's not the squeezing that does it, it's simply having skin contact on the left edge which increases the antenna strength.
To prove it, you can use the https://play.google.com/store/apps/details?id=com.chartcross.gpstest (GPStest) app to monitor how the GPS unit is doing locking to satellites. If you aren't holding it, sometimes it will lock, but other times it'll just sit there unable to obtain lock on enough satellites. When that happens, I hold the phone for a little bit and locks every time.
On rare occasions, it'll lock to a bunch, but then go into a weird bug mode where it alternates between no-lock and locked. In that case, simply toggle GPS off, then back on.
I've had decent success once it's locked onto a good number of satellites (more than 10), you can let go of the phone and it'll usually stay locked.
So when you're on a plane, GPS will not update rapidly. A phone uses a combination of data and GPS to get your location much faster than a "cold" GPS sync. If you're 2 hours into your flight and you open Google Maps, the location marker will be gray and at your departure airport. A full sync may take a whole minute of leaving your phone on actively searching for location (the GPS icon in the status bar for Android), and only if you're holding the phone by a window.
There's a good free app (for Android at least) called GPS Test that will show you the GPS unit's status and acquired satellites so you know when location is acquired. Or, you just leave Google Maps open and be super patient until the location indicator turns blue.
Once you have a location fix, location services will take over and sync later when you have data. If you have geotagging enabled for your camera app, you can use that. GPS Test has a Share button that will copy your lat/lng to the clipboard.
I do it using using GPS Test. To get the time to lock click on the square at the bottom left hand corner with a radar in it. The first fix time at the bottom right is the time taken to get a position lock.
With A-GPS enabled:
- Install the app.
- Start the app.
- Go to the 3-dot menu and choose location services.
- Set the location accuracy to 'high'.
- Return to the app.
- Go to the 3-dot menu and 'Update A-GPS Data'.
- Wait.
- It should take somewhere between 2s-60s.
2s is good, 60s is bad if you are outside with clear skies. While 60s may be acceptable when inside.
Without A-GPS enabled:
- Install the app.
- Start the app.
- Go to the 3-dot menu and choose location services.
- Set the location accuracy to 'device only'.
- Put your phone into airplane mode.
- Return to the app.
- Go to the 3-dot menu and 'Clear A-GPS Data'.
- Wait.
- It should take somewhere between 20s-180s.
If you are inside you may never get a lock, however outside 20s is amazing and 60s is good. 180s is on the longer side but in most cases it's acceptable as long as it doesn't lose your position too often.
I just dealt with this last week on My N5. After a bit of research I came across this app:
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
The page I was reading said that outside, I should have 4 bars hitting at least 30 for the GPS to be accurate. The signal I was getting was very poor. The GPS antenna is on the back plate of the phone and apparently wasn't making good contact with the phone. I followed the instructions here:
https://www.youtube.com/watch?v=QBpNtWvY454
Immediately my GPS was performing much better.
Your phone's GPS relies on Assisted GPS, which uses cell data to rapidly get a first approximate fix.
When you don't have cell data, it will take your phone longer to get a fix by listening to GPS satellites. This may take up to a minute of active listening.
If you're using something like Google Maps, you need to keep the app open and keep the phone from sleeping while it gets a fix. Maps will place the position correctly, even if you don't have high-resolution map data downloaded. Download map data for the area in which you're traveling ahead of time so it's cached.
There's also a great app called GPS Test (Android link) that shows satellite signal strength and a status indicator for when your phone has obtained a fix. This shows you if you are truly unable to reach GPS or if it's just taking awhile.
Sounds like you've got a problem with the GPS hardware in the phone. You might find better ideas for how to fix this in /r/motorola/.
I used to have issues with the GPS on my phone but over the years I've since flashed newer roms and radio firmware and the problems don't happen anymore. But back when they did I had a lot of luck using this app: https://play.google.com/store/apps/details?id=com.chartcross.gpstest
Open it up and tap the three line menu icon in the top right. Then tap AGPS>Clear and Update. Hopefully after a few seconds to a minute the GNSS status box will say "3D Fix" which means your GPS location is good. I would do this every time google maps or any map app didn't work right and it always did the trick, at least for a while. Hopefully it does something for you.
On Android I use GPS Test.
I just wait until the accuracy is on 3 m (I don't think it's possible to get anything lower on a phone) before I take the coordinates.
>When using Google Maps, I get a precise location but no "direction cone". I also checked with another app (GPS Status) and there the compass does not work. Direction changes have no influence / compass is "fixed". Baseband-Version: G900FXXS1CQA9
Compass works fine in both Google Maps (direction cone) & GPS Test by Chartcross on my S5 G900M LineageOS 16.0 klte build 2019-03-18 + Open GApps Pico + LineageOS Addonsu with the most recent modem, bootloader & TWRP for my model.
Having the most recent modem for your S5 helps. I described here with screenshots how I updated my S5 using haggertk's Odin flashable bootloader & modem combos: S5 Odin Flashable Modem & Bootloader
He has a package with bootloader G900FXXU1CQK3 and modem G900FXXU1CRH1 (2018) for the S5 G900F. The higher the last 4 alphanumeric characters, the most recent it is. Your G900FXXS1CQA9 modem is from 2017.
Haggertk is the S5 klte + variants LineageOS maintainer & one of the LineageOS project directors.
I like this app. It picks up location from GPS/GLONASS/etc.
Shows lat-lang, speed, local time, sunrise-sunset time, & a few more info.
Can save current location very quickly. (2 touch I think)
Superbly customisable (in the paid version)
Does it get a 3D fix with this GPS Test app?
Try turning off LTE ( or ejecting the Sim card), turning on only Device only location, getting a GPS fix with that and re-enabling the LATE/reinserting Sim.
No. But if you have GPS stability issues. You could try downloading GPS Test and try manually update your A-gps. Your phone (just like mine does) might not be updating to new satellites automatically. You can do this by tapping the menu button in the top right and hit update a-gps. I have to do this every time I play PoGo otherwise it could take up to 20 minute before i'd have a stable GPS location.
Give GPS Test a shot, see if your phone is finding satellites and if they're locking. Also, the app has a feature to clear and update A-GPS to refresh those settings.
I don't have the same phone, but this has fixed some intermittent and similar issues for me before: Open this app, wait until the indicator in top left says "3D Fix" then immediately swap back to Pokémon GO. Also try opening location settings on your phone, killing (via Force Stop button) all apps that currently or recently used location services, then try the above.
I have no idea if this will work for you, but it might be worth a try.
If you're on Android, have a look at GPS Test https://play.google.com/store/apps/details?id=com.chartcross.gpstest you'll be able to check the strength of your GPS (and GLONASS, etc…) signal. That could help you trace your problems. If you're on iOS, I guess similar apps exist. Good luck! Edit: you're obviously on Android, so all fine. Do as DuckSaxaphone said, but you can also check if your phone maker didn't add some option to shut down (or slow down) apps when the screen is off, in order to save battery. On my Xiaomi, I need to put a "lock" on the app in the change app menu if I don't want it to go out of memory after a couple of minutes in the dark.
Not exactly sure what you mean here.
This GPS Test app has a feature to clear and update AGPS data. https://play.google.com/store/apps/details?id=com.chartcross.gpstest
You can do that while you have data connection. And then GPS will lock faster when fully offline. AGPS data needs to be updated from time to time though.
I did a AGPS update with a GPS testing app in playstore. https://play.google.com/store/apps/details?id=com.chartcross.gpstest
Once it did the AGPS satellite update I was off and running.
Plus of course make sure you give the apps permission to use your GPS / etc.
TimJ
use GPS Test on play to reset your APS, https://play.google.com/store/apps/details?id=com.chartcross.gpstest
Make sure you're outside in the open and be prepared for it to take a while to get a good fix.
Try checking your GPS with a testing app that shows your connection to satellites: https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en
It's more likely that it's a software issue than a hardware issue. You can try some apps like GPSfix https://play.google.com/store/apps/details?id=com.androidlab.gpsfix&hl=en to help dial in your location quicker.
If that fails, factory reset and clean install of your ROM.
Install this app and go outside.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
The counter in the corner tracks how many satellites you can see. You should see 8+. If your phone shows less than 10, and takes longer than 20 seconds to get a lock, or never gets a 3d lock, then you have the issue.
Both mine and my wife's G5 had this problem and we got them exchanged for $25 each through the carrier, without insurance.
My OPO's GPS shits the bed pretty regularly.
I've found that when it happens I can "fix" it for a while by using https://play.google.com/store/apps/details?id=com.chartcross.gpstest
Right after I reboot I go into that app and "clear AGPS" then "Update AGPS" and wait until it gets a 3D lock. After that I'm pretty solid for a while.
I'm not all that hopeful it will help you. I have no idea why it works for me.
I have had this problem with a couple phones. Happens most often when I travel. I use GPS Test but they both work fine. Go through the menus to "Clear AGPS" then "Refresh AGPS". Usually works like a charm.
Have you and your wife install GPS Test and see what it tells you. It shows you a great deal of information about the GPS functions in your phone.
I solved past issues with my phone's GPS using GPS Test. It can diagnose issues, and update your AGPS which can help improve the lockon speed (May be a paid feature). It may also help to recalibrate your phone's compass when you have Waze open.
Here's what fixed it for me after flashing Cyanogen OS 12 (2I3). I ran GPS Test and cleared AGPS then updated AGPS. Now I get a GPS fix in 5-6 seconds.
You're right - WORKED LIKE A CHARM!! Thanks so much!!
FYI (for any future readers): If your GPS doesn't lock immediately, download GPS Test from the Play Store, and hit "Clear AGPS" followed by "Update AGPS"
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
I use this app if I start drifting to see how my signal is, usually after opening it I pickup more satellites and then switch to ingress and everything is gravy.
Because it's not nearly so cool to fly at Mach 0.88 and 36000 feet.
The IFE system, if present, should tell you speed, altitude, etc. You can also use a phone app like https://play.google.com/store/apps/details?id=com.chartcross.gpstest
Thank you for sharing this. However, we have checked our community and others do not experience the same problem.

Look, it's not perfect, but most flagship smartphones will pull a GPS Speed on a good app like Torque or literally GPS Test will pull within a 2% variance over your actual speed (so you're slower than indicated) most of the time (in my experience)
They're programmed to read over, not under.
Unless you use a programming cable and can set the circumference of the tire in cm/mm, it wont be accurate at any setting.
Changing the setting to a larger tire will fool the controller and you will go slower, setting it to a smaller tire will make you go faster as the speed is calculated from the magnet/sensor on the wheel. Your speedo will not be accurate at all, use your phone and a GPS app > https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en\_CA&gl=US
Possibilitity:
Your phone in your new car is in "radio shadow" caused by the dashboard or other obstructions (such as certain glass tints)
Consider downloading GPS Test from Play.google.com
You can try to fix the gps with this app: https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=pt_BR&gl=US
In an open air place click on the 3 dots above on the right and click on AGPS/Clear and update". Then wait about 5 minutes or so until 3D Fix appears in GNSS Status. If it doesn't work, restart the device and try again.

Install this:
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
Check if your time is acceptable - eventually also enable "set time zone based on location" (the time from most carriers is surprisingly wrong very often).
If it still does not work after like 15 minutes outside (power-saving disabled) try in the program menu - AGPS - Clear and update.
If it still does not work enable developer options and activate "Force full GNSS measurements".
Did you install LineageOS then reboot in recovery & install MindTheGaps in one go without rebooting in system in between as described in your device's installation wiki?
As seen in a blue box in https://wiki.lineageos.org/devices/instantnoodlep/install#installing-lineageos-from-recovery :
>NOTE: If you want the Google Apps add-on on your device, you must follow this step before booting into LineageOS for the first time!
You wrote in the OP "I even installed a GPS Test app".
Is that GPS Test by Chartcross and do you get a fix?
FWIW on my Galaxy S5 G900M LineageOS 18.1 klte build 2022-01-30 + MindTheGapps third-party apps see my location.
You can try to fix the GPS with GPS Test app. In an outdoor location tap the 3 dots at the top right, tap AGPS, then tap Clear and Update. Wait about 5 minutes in the app until it gets a location and your GPS will be working again.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=pt_BR&gl=US
>u/Timbred - ...No Google Location Service with latest builds ...This issue also appeared on my Galaxy S5 when I recently upgraded from Lineage 17 to 18, also using the latest build
FWIW on Galaxy S5 G900M LineageOS 18.1 klte build 2021-11-14 + MindTheGapps both Maps & GPS Test by Chartcross (Fix accuracy 3 meters) work fine.
In April 2021 I upgraded from 17.1 + Open GApps Pico 10 to 18.1 + MindTheGapps 11 without wiping the Data partition so not to lose my apps & settings.
BTW "Newest" or "latest" will not mean a thing for future readers after the next update so including the build date & LineageOS version is good practice IMO. ;-)
Bugs may be created by a merged patch in a given build date for a given device & solved in an other build.
I use my phones GPS and the GPS Test App, it pulls up to 24 satellites at any given time, its super accurate. No need for extra gear when the phone does most all of it.
Look at
- Urban Biker
- Trail Forks
- Google Maps
You might try this app, to see if it is indeed the GPS.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en_US&gl=US
Unfortunately, viewing Waze via Android Auto may introduce problems of its own.
To check your GPS sensors, try this app:
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en
It will check connectivity to GPS satellites, AND display a compass, so you can check your sensor.
I used the GPS Test app; I think they serve the same purpose. I found in Hungary, where I live, the Galileo has slightly bigger presence.
You can use an app like GPS check to actually see what the GPS receiver in your phone sees.
I'm also not sure how you'd disable google location services specifically on your firewall? They work in your phone and don't require anything other than SSID and working connection to Google/Apple servers at some point (it could be fair bit earlier as this information is cached).
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
If you're on Android, you can check your GPS sensors and how accurate they are.
My guess is way more often than the wifi and cell tower triangulation.
You can try this app:
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=pt\_BR&gl=US
Open the app, click the 3 dots above on the right, click AGPS, Clear and update, wait a few minutes and the GPS should work again. This should be done in an open place, not indoors.
Android or iPhone?
I'm on Android and I use GPS Test which is good for all the basic functions and showing you where you are now. Free, but has zero navigation capacity.
For navigation, I use Mapfactor Navigator (also free) which downloads maps so it is good for rural or no-signal areas, but poor support for trails and walking.
I've also seen a number of people report it on various reviews of the phone online.
I think it's actually a hardware issue.
If you use an app like GPS Test, how long does it take to get a GPS lock when have a clear view of the sky? In my case, it takes a really long time - 2+ minutes, even though it can see lots of satellites. I compared it to my wife's phone (a Xiaomi), which consistently got a lock in under 10 seconds. I also tried clearing/updating the AGPS data, which doesn't seem to help.
I had a similar problem with a Samsung Galaxy S3 phone years ago. On that phone, whenever it started to have trouble getting a GPS lock, all you had to do was take the back battery cover off, and tighten the screws that held the back of the phone on. (That was back when phone backs weren't glued on.)
There are a couple of methods, here's what I would use assuming you use a smart phone and no handheld gps device.
1) Install an app that gives you the data from your gps. There are several, depends on your phones operating system which you should get. I have Android and use GPS Test 2) Find your spot. 3) Approach it from a direction (let's say north) 4) Once at your spot, wait a few minutes for the gps to settle, then record that number. 5) Walk away, then approach from a different direction (such as south). You want to walk away at least 50ft or more, so that the gps chip picks up that you've moved and is tracking your new location. 6) Repeat Step 4.
What you then really should do is repeat all that again a few times, at different times of the day. Different satellites, different atmospheric conditions, different aircraft overhead - lots of little things can affect the numbers that you get. Once you have enough samples, you average them.
The more samples you get, the more accurate your result will be. If you invest the time to get lots of samples (especially if you can use more than one type of device) then your coordinates should be accurate. Many new people get over-excited, grab one number from the official app and call it done. Then people have trouble finding their cache due to the number not being very accurate.
The above seems complex, but it seems harder than it really is when written down. Putting out caches requires a little bit of effort and ongoing care to maintain the caches, it isn't for everybody but can be very rewarding (and frustrating).
I love the Gingerbread and Ice Cream Sandwich comment! But seriously, I had a problem like this with Lollipop.
To fix it THEN, I used GPS Test (https://play.google.com/store/apps/details?id=com.chartcross.gpstest&) and reset the AGPS data.
The details are here: https://blog.benmoore.info/2015/08/oneplus-one-gps.html
Give that a try!
This app give you a display of signal strength of connected satts.stats. app my roof has a crushing effect on the signal, even just covering phone with hand with cut it in half. My drone will my get a lock in the car and at work we have had issues with older dispatch equipment but the new stuff is better. Might consider adding a shark fin to the roof. On factory cars they have radio and GPS in them for this reason.
Some phones come with a built in barometer so maybe you should explore that option as well. Also check out GPS Test.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en
Can you use a GPS test app to see how many satellites are in view/use and their signal strength? I've used this one before:
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en_GB
is your phone in a case with any metal in it? do you have a metal or magnet (for a mount)?
were you holding your phone, was it in an arm band, a waist band, or a pocket?
when you open google maps, and you let it grab your location, does the wide blue circle eventually go down to the size of the dot of your location?
does your location jump around when you're using navigation?
lastly, have you checked to make sure you're getting a good lock on multiple satellites using a GPS Test app like this? https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en_US
The accelerometer has nothing to do with your GPS. Where are you and where are you testing your GPS?
Also, this is a far better GPS testing app.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
It happened me too, I used the GPS Test application and since 2-3 months it working stable.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
I follow that steps: 1. In service settings (phone ##7378423##) GPS/purge assistance data, 2. Go GPS Test application in APGS options choose clear only, 3.APGS options again and this time choose update only ( not choose clear and update idk why but I saw in a video ), 4. Wait like 2-3 mins, in view and in use satellites will be appear.
My GPS works great! Every photo I take is even GPS tagged. Try this app and see how the GPS performs.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en_AU
Try app like GPS Test.
It shows the signal strength to each satellite.
It helped me to diagnose a problem on my nexus 5 where the GPS antenna connector got loose
Have you booted into safe mode to check it? This app might help you debug it a little more.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en_AU
Very interesting. How much time are you giving to the Maps (or other app) to achieve a GPS lock. Have you tried another app, like GPS Test?
Yeah i'm not exactly sure, but I can imagine them being antenna contacts, that's the way it was in my HTC One X many years ago. I would do some speed tests to make sure you're getting proper LTE speeds as well as using an app like GPS Test (https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en_US) to make sure you're getting a position lock with good accuracy
OK. That is probably running Android 7.1.1 (Nougat)
Go to the Android App store, and search for an app called GPS Test. Install the app, and activate your GPS.
If your phone is working well, and if you are not inside an area that has poor GPS reception, you should see a signal within a few seconds. You will also be able to see a map of the GPS satellites. AND there will be a link to push to update your AGPS.
(AGPS is used to get GPS locations faster, by scanning nearby cell towers to approximate your location).
If it takes a long time to get a GPS signal, there may be a hardware problem with your phone.
First thing you need to check is how many GPS antennas your phone is able to connect to.
You can check from this app https://play.google.com/store/apps/details?id=com.chartcross.gpstest , and see if you are able to triangulate the position.
​
If you dont have a 3D fix, then try calibrating your compass, gps.
​
If that also doesn't help, then its a Hardware issue.
I just tried, I got locked in with a few BDS!
Together with GPS and GLONASS, I have 16 satellites locked in, that is great, location only takes less than a second to show up!
I used this app to test https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en
thanks for adding info.
> and my research is in gps
wow.
this GPS app in my phone says it can see so many satellites and uses multiple of them (often between 9 & 12). and it shows altitude info.
How does it work ?
Did your phone come from abroad? The reason I ask is that GPS tracking is divided into timezones and it may be that the default zone for the phone is the other side of the world, so it's not registering any of sats it's looking for.
Try GPS test and in the menu there is an option AGPS - Clear and Update. Then leave it on and searching. This can take up to half and hour to update, so patience is a virtue.
Make sure you have power saving turned off, as well as the latest version of maps.
If that fails, try flashing the phone with an updated firmware from your region/provider.
It seems it knows there should be 23 satellites in view, but it's not getting a fix on any of them.
Make sure you test it outdoors where you have line of sight to the sky.
Another app is https://play.google.com/store/apps/details?id=com.chartcross.gpstest which has a more user friendly interface.
Not sure what the problem could be. Only other thing I could think of is try resetting your AGPS. Try this app.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
I actually use this app to clear AGPS (clear only option) if I start rubberbanding too much while spoofing. But there's an option to clear and update AGPS which is what you would want to try.
Make sure your GPS hardware is even working:
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
If it can pinpoint your location correctly, then you can go back to Google Maps to figure out it's problem.
Ada setting power-saving yang nggak sengaja ke switch? Kalau pake GPS Test dan duduk di tempat terbuka, dia bisa lihat satelitnya nggak? Di Location Services di settings pastikan mode nya di High accuracy.
OnePlus 5 bought in September.
I used to have issues after 2-3 days of up-time, the only satellites it would connect to were GPS and GLONASS.
I have the latest OOS, I tried GPS in airplane mode, I had 29 satellites visible, GPS, GLONASS, BeiDou and even one Galileo, and it connected to 13, near a window.
350h uptime.
P.S. I use this to check GPS info https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en
>GPS is completely wrong in a particular location alone...
It reminds me of a certain man that thinks he is at the center of the universe.
You can try clearing AGPS data using.. https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en
I think goldensnakes is correct .. I think you may just only need to clear the cache and kill the app...
Try using GPS Test:
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en
right after you reboot and look after the number of satellites and levels.
First GPS lock might work differently if you have cellular data and wifi turned off. On some cellular providers if you have the cellular data active A-GPS makes GPS lock almost instant.
I have a GPS issue with my phone. I used GPS Test to see what was going on, and it identifies satellites, but none of them seem to be affecting the device?
I want to know if this is a hardware or software problem and a possible fix? Edit: Running Android 6.0.1.
The navigation chipset/antennas on the N8 seem pretty good. I compared it to the S7 Edge and it was an improvement (probably because now it also supports the Galileo constellation).
Try this app to see what you're picking and SNRs of GPS, GLONASS, GALILEO and BEIDOU. https://play.google.com/store/apps/details?id=com.chartcross.gpstest
As for simple orientation (usually only noticeable while walking) you do need to calibrate the magnetic sensor now and then.
there's an app called GPS test which shows you how accurate your GPS is as well as being able to reset it,
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en_GB
What GPS setting have you got enabled? High? Device Only?
Weird, the S7 was one of the harder phones to GPS spoof with because it has such a good GPS signal. Maybe try THIS app and clear/update teh AGPS data.
More information may be needed, but as others have stated:
POGO needs to have Location detection set to either High Accuracy or GPS (not WiFi only)
Mock location cannot be enabled in the developer's settings (even if she is not running a mock location app, this option needs to be disabled.
You can test the GPS signal strength with apps and you can improve location detection by going into Settings>Location>Improve Accuracy and enabling WiFi scanning (and Bluetooth scanning)
Try GPS Test: https://play.google.com/store/apps/details?id=com.chartcross.gpstest – the compass pane shows “High magnetic accuracy” in my hammerhead, but Google Maps occasionally advices me to recalibrate by moving it in a certain figure-8 pattern.
I tested it yesterday (clear blue skies, not sure if that makes a difference) and it took 19 seconds to lock using GPS Test. I was on foot and it was the first time I'd turned on the location toggle in a couple of weeks.
When I was on MIUI (int dev), it couldn't get a lock at all.
I use https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en
But there are lots of Apps that do the same.
But it may be an A-GPS problem which there are guides out there on how to clear the cache and update it to fix it. The Update took me around 5 mins and it reduced drift I once had. Tho I do it after each Android System Update.
I see what you are trying to do... I'll take a kick at it. On my android I have an app called GPS test. It will give you your co-ordinates for latitude and longtitude. It includes a map of the world but really what you want to communicate to people is the lat/long. Take a screen shot and email at the end of the day, or text the co-ordinates. You will need phone coverage or data. The people on the other end can use google to input the co-ordinates and see where you are. Example of screen shot is here.
You could track a small portion of your day using an app (and make sure your phone is in airplane mode). You would need a 10,000 to 20,000 milliamp charger to get your phone through a week....
The fix is quite easy if it ever happens to you. Download one of the GPS apps out there that allows you to clear the GPS cache. Once you do that it clears it right up or the most part. Something gets corrupted and at least one of the satellites it locks on to is corrupted as the history is wrong from what I've read.
this is the app I used: https://play.google.com/store/apps/details?id=com.chartcross.gpstest
These are the instructions:
I don't need to keep running the app or anything, the app's only permissions needed are internet access for the ads, so there's no push notifications with it. (It also seems to have been around forever, since 2012). Once I clear those two settings I'm good for months usually.
i wonder how those would be visible in gps debugging apps, for example GPS Test shows gps satellites with numbers 1-60 (circles) and glonass ones as over 60 (triangles)
Lg phones have had overheating and GPS issues. Either could be affecting you.
Download this GPS app and see if you get a GPS lock. If it takes more than ten seconds or so, there is your issue.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
You should see something like ten plus satellites and definitely get a 3D lock in under twenty seconds at most.
Better to download a GPS testing app.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en
For example. With that, when I start the program, I instantly had 28 satellites "in view" but no GPS fix. 30 seconds later I had 7 locked in and a 3D position locked in, with 200 foot accuracy. 15 seconds later it was locked in on 16 and 30 foot accuracy. Not great, about par for the course for pure GPS tracking - but I am sitting indoors...
Fast. Out of five tests with GPS Test and location services set to GPS-only, three times I got a full lock in 1 second. Once I got 2 seconds, and once 10 seconds. Accuracy hovers somewhere within 10-30 feet.
The GPS/LTE issue centered around losing data connectivity after location requests. The location info itself continued to work, so I'd say your problem isn't related.
You can try looking at your GPS signal levels with something like GPS Test. See if that app has difficulty making a fix at the same time Strava is acting up.
You don't need Internet to get a GPS lock. Furthermore, if it works on your mom's phone but not on his that would indicate the problem is isolated to his phone; not your mom's phone or the hotspot.
On his phone I would download GPS Test from the Play Store and see if he can get a lock. Make sure GPS is enabled and it is set to "High Accuracy" before doing the app. If it doesn't work troubleshooting GPS issues is usually no fun. Might need to factory reset or use a utility to restore the phones original firmware.
If you are on android, install this app and go to the settings on te top right (three dots) and press clear a-gps followed by update a-gps. Had the exact same problem on my phone and this managed to fix it.
download GPS Test and keep your phone near a window for 15-30 minutes. If it doesn't gets a lock, then we can try more advanced things.
Try a different map app. HERE maps for instance.
Also, get this https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en and see what it tells you.
Now, about GPS in general:
Keep in mind, getting a pure GPS fix (which is what this tests) takes a while. 30 seconds, a minute, maybe even more is normal. That time goes up as well if you have a big "jump" - like, say, putting the phone in airplane mode in location A and flying to location B. When you turn the GPS back on, the cached data it uses to speed up satellite acquisition will be out of date and "confuse" it for a while.
Also, GPS accuracy can be affected by specific car types. Especially if you have something like an electrically heated windshield, the thin thin wires in the glass will wreak havoc with GPS signal to the device if it's on the dashboard. The car itself is a metal cage, which is perilously close to a Faraday cage. In the earlier days with the iPhone, Tomtom sold a car phone mount that had a GPS amplifier just to deal with that issue.
Also, make sure the device is on the dashboard and under the glass. If it's in the backseat or some such it will get a much worse signal.
Also - in cities, with many tall buildings, GPS works less well also. The signal bounces off the buildings and line of sight to satellites is randomly occluded as you drive. AGPS compensates for this somewhat, but GPS will work less well in cities regardless.
I'm not saying the G5 doesn't in some cases have a GPS issue, clearly it does. Just saying that even with a fully functional device, numerous outside factors can cause real problems with any GPS enabled device.
Assisted GPS:
>Standalone GPS provides first position in approximately 30–40 seconds. A standalone GPS needs orbital information of the satellites to calculate the current position. The data rate of the satellite signal is only 50 bit/s, so downloading orbital information like ephemerides and the almanac directly from satellites typically takes a long time, and if the satellite signals are lost during the acquisition of this information, it is discarded and the standalone system has to start from scratch. In A-GPS, the network operator deploys an A-GPS server. These A-GPS servers download the orbital information from the satellite and store it in the database. An A-GPS capable device can connect to these servers and download this information using mobile network radio bearers such as GSM, CDMA, WCDMA, LTE or even using other wireless radio bearers such as Wi-Fi. Usually the data rate of these bearers is high, hence downloading orbital information takes less time.
Basically, your GPS downloads some data online to be more accurate and faster to sync. There is indeed apps and other methods to clear that aGPS cache. This will force the GPS module to update it's aGPS data and maybe fix OP's issue.
I saw an option to clear the aGPS cache in the following app: https://play.google.com/store/apps/details?id=com.chartcross.gpstest
But I can't guarantee it works on all phones.
В железном автомобиле GPS работоспособен, а в алюминиевом самолёте неработоспособен? Вы это серьёзно?
Вот смотрите, я три года назад провёл такой эксперимент и смотрел на GPS Test в полёте:
http://piccy.info/view3/9004967/fe115dc1c6703f639c0f7b147c04728f/
(Желающим повторить эксперимент напоминаю о том, что почти во всех самолётах во время полёта смартфон надо переключать в «режим полёта»; на приёмник GPS-сигнала этот режим не влияет).
What do you want it to do? Navigate? Probably just use Google maps. Test out out the reception? check this out. I'd go and have a look at /r/android too.
I'm sorry. The default formatting in my reply doesn't make it clear that I included a link to GPS Test in the Play Store. Here is the link: https://play.google.com/store/apps/details?id=com.chartcross.gpstest If you tap the three dots in the top right corner you get choices to Clear AGPS and Update AGPS.
What does it look like if you run the GPS Test application? When it's in its fail state, can it see any satellites, or are they just considered too weak to lock onto?
Your phone is probably already using both the American GPS and the Russian Glonass. If you use GPS Test the Glonass satellites are numbered 65-96, they're also triangles unlike GPS that's round on the sky view.
More satellites will mean better accuracy.
This was true when GPS was the only thing in town. But these days people refer to GPS for the technology more than the US satellite constellation.
Now there are 4 fully operational global positioning satellite constellations:
- GPS (US)
- GLONASS (Russia)
- Baidu (China)
- Galileo (EU)
2, 3 and 4 all provide much higher accuracy than GPS alone already and these days most new phones support all 4 or at least 3 out of 4.
I don't know about the rest, but Galileo is specifically designed for non military usage and provides the highest accuracy, much higher than GPS. My smartphone can see around 40 satellites about 14 are GPS, 15 GLONASS and 12 Baidu, mine doesn't seem to support Galileo but a lot of them do already.
Another interesting fact, Galileo is designed in such a way that the signal is impossible for it to be jammed by anyone rogue. Which is possible with GPS and even US government will block access to it during war time.

You have to download the GPS Test app.
I hate the GPS on mine too...
I have to use a GPS test app to get a lock and then switch to Google Maps.
Give it a go.
I don't know if this is common. I have two V20's in my family. GPS works ok on one, and not so great on the other. Neither is as good as my Note 4.
I think the GPS antenna is in the plastic end piece at the top of the phone. If you google, you'll find people talking about the the contacts in there. For example:
https://www.reddit.com/r/lgv20/comments/7fx2gz/becareful_buying_the_top_plastic_bezel_of_the_v20/
There is also no need to drive around. Get a GPS testing app that shows your signal strength, for example:

I guess you did not install a GApps package, right?
If you go outdoor for 10 minutes with an unobstructed view of the sky can you get a first lock with one of those GPS apps or similar?
It's very useful to have a simple app installed that just shows basic GPS info and tells you whether your device can get a valid location through the GPS signal.

>u/DeeHasty82 - I'm looking to root/custom rom my OnePlus 3 ...but how do I get a reliably working GPS on a custom rom?...
As you can see in https://wiki.lineageos.org/devices/ the OnePlus 3 / 3T codename oneplus3 is supported by LineageOS @ the present.
For a ROM to be accepted in the LineageOS roster it must meet the strict LineageOS Device Support Requirements Charter where you can read:
>All devices with GPS supported in their stock OS MUST support GPS.
Just make sure you update your device to the most recent manufacturer's firmware, as older version may affect GPS performance, before flashing LineageOS & test GPS outdoor with an unobstructed view of the sky for the first fix.
>I've used Lineage ...on past devices, but I've never been able to have a reliable GPS signal.
I don't know if you are talking about official LineageOS or unofficial, which devices you are talking about or in which region/country you live but I have GPS 3d Fix & 3 meters accuracy on GPS Test by Chartcross or SatStat on F-Droid & Google Maps works fine on my Galaxy S5 G900M LineageOS 16.0 klte build 2020-01-06 + Open GApps Pico + LineageOS AddonSU for root.
With an old Galaxy S3 with the last official LineageOS 14.1 for it the GPS also works fine in Costa Rica.

Try GPS test. It gives you signal strength data.
Try running GPS Test and clear AGPS and update AGPS. That helped me when I went to COS 12 and COS 12.1.
Check your speedometer. Many under-report speeds, so while you think you are going 25 mph, you might infact be doing only 21mph, which would certainly annoy other drivers.
GPS Test for your phone gives accurate speed measurements when travelling in a straight line. (it will never under-estimate speed, but with poor signal could slightly overestimate). Get a friend to help.
Use GPS test from the Play Store. Are you seeing any satellites at all? If you're never seeing any signal, it might indicate a hardware problem.
https://play.google.com/store/apps/details?id=com.chartcross.gpstest
Check your location settings that it's set to High Accuracy rather than Battery saving. Even change to Device only if you want to be sure.
There are also GPS apps that you can try (I favor this one) and see if they can lock on.
Worse comes to worse, nandroid then restore Sense ROM to see if GPS issue is a device problem, or 'NuSenseSeven' problem.
Good luck
Thanks, here's the link.
Edit: you may want to play with it a bit to get used to it. It'll show you how many satellites in view and the number locked at the top. Below those is a bar chart of the signal strengths. Finally bottom right on the satellite radar is the first lock time. You can delete A-gps data by accessing the menu and set the GPS mode to device only in location settings which will mean the phone will have to obtain your location using only the internal gps.
For the record, the Android app GPS Test will tell you how accurate your phone's GPS signal is in feet (and possibly meters). Lots of other interesting info, too, like which GPS satellites you're getting a signal from.
This is actually a very common problem, and if I recall, it was present in many N900* models (like the Canadian N900W8). Samsung is aware of it but won't acknowledge it, and an AT&T representative confirmed this. A variety of software problems existed with this phone and its GPS; for this specific issue, had the users owned their phone since Jelly Bean, they would have experienced this issue after upgrading to ICS.
For many, the contact adjustment (as mentioned elsewhere in this thread) won't fix anything. It is a software issue, and a special patch exists for rooted phones to fix the issue. This GPS problem appears to be very similar to the software problem on the surface, but be caused by different issues.
For me, the problem existed from my very first attempt at using the phone. Samsung and my provider said to send it in for servicing. I included their standard note indicating steps taken so far and ways to reproduce the problem. I received the phone back with a note saying "Flashed phone. Tested: works", even though I flashed it myself with no success, they should have read that, and they should have at least said that they tested the GPS specifically so that I wouldn't doubt their competence. I couldn't even hold my phone until I signed a form from the provider saying that I have my phone back and I've confirmed that it was fixed (don't get me started about how wrong that is). Tested it, and it was no different: still broken. I called my provider back, and they authorised a swap. I got a new one, and the same problem existed. I called them back, and we agreed to switch me to an S5. I sold it and switched to a Sony Xperia Z Ultra, which has been blissful (although I do miss the S Pen).
During the shenanigans, I was able to do something that would trick the GPS into working better, usually (but not always) until reboot. Someone suggested testing it with different cellular modes (e.g., with LTE turned off). I tried it once, and it did work, but then I could never reproduce the success of that attempt. I tried some creative things, and found that it was easiest and most reliable to:
Install the app GPS Test and open it when you're in an area that you know should have some good GPS coverage.
Go to the settings button at the upper right and go into the settings. Set the device to keep the screen on.
Go back to the settings button and choose "Clear AGPS", then go back and choose "Update AGPS".
Wait (with the screen on) until it gets a GPS lock, which should be more successful than usual. If you do anything during this time, it will stop and have to restart.
Once the lock is obtained, you can close/quit the app (even from multitasking) and GPS signal should be more reliable than before. It will need to be done after every reboot, and perhaps at other times.
I came back to this subreddit to see if anyone has made posts about the GPS being fixed since updating to Lollipop, but only found this post. Hopefully this helps.
I would try the following:
Download the GPS Test app. No root needed.
Start the app. At the bottom of the apps screen, are choices for the displays. Choose the leftmost one, it looks like a coordinate circle. You will see number of satellites uses, etc.
From this screen, at the upper right, click on the three dot menu. From the dropdown menu, select AGPS. From the pullout, select "Clear and Update"
See how this works out.
