Hi all, i have tried to find similar thread with "search" before opening this one, but this function is not working right now to me.
The problem: usually my Artemis integrated GPS works very very well, for weeks (cold fix in not more than 2', also without downlaod of efemeridi, and hot fix very very fast, with 7-10 satellites hooked). But in some days/weeks/periods the gps doesn't work well. In particular the cold fix (first fix) needs some minutes (5'-10'), and once the fix happened, the signal of each satellite hooked is really poor, or the number of satellites hooked is low and instable; for eg the gps hook not more than 3-4 satellites, and loose and find the signal continuously. And also other fixes during the day ar slow if made just after few hours from first one.
The strange thing, as said before, is that usually the gps works very very well, for weeks. But expecially during the winter it happens that it works bad for days/weeks. And without any operation after some days/weeks it turn working very well again.
The issue don't seems to be linked with bad weather days. Can it be related with seasons and relative different position of satellites in the sky?
Untill now i never found other guys with a similar problem on their Artemis device. So now i ask here for support.
Which could be the problem? And which is the solution?
Thanks in advance for support!!
PS i use WM5 original. The issue happened since first year of life untill now (i just did an hard reset). And the issue happened both with TT6 and TT7 (just installed).
I have a problem with my Defy.
The GPS doesn't seem to work properly. I've tested it with GPS Status & GPS Test...it detects satellites but doesn't use any of them to locate the cell phone.
A few days ago, I've succeed to get a localization but since it doesn't work.
I've just reboot it so that I'll have the manufacturing settings but, it still doesn't work...
Can someone be of any help ?
Thanks.

Have you tried calibrating the compass in the settings? I had what sounds like a similar problem and I did that it worked for me.
Have you tried going into airplane mode, then using the GPS?
The compass is calibrated.
I've tried to turn on the airplane mode & then to launch the gps...same result no satellite in use, no localization...
I tried the GPS today, no airplain mode, defy was working as usual. I had to wait quite long time to get the fix but then no issues. FYI compass was already calibrated.
Since your defy is able to detect the satellites it should not be an hardware issue, i guess you were using pre-installed gmaps and navigator, have you tried any other software which makes use of gps location? (e.g. TrackMe)

Yes, that's what I think, it shouldn't be a hardware issue...
I tried with the apps GPS test & GPS status which were not pre-installed and it doesn't work either...

I can't figure out what's causing your issue... but, take a look here:
https://supportforums.motorola.com/thread/40896
maybe it could be helpful, second post of cheaplikeafox, he's talking about a gps reset (made through GPS status) which solved the problem. Did you try that specific option in GPS status?
Sadly, I've already tried...arf...I don't what to do.
Maybe I should try with other Motorola phones' owners...

Just to be sure, are you trying to use the GPS without being in "maps" that came with the phone? But on a separate set of installed maps? Except for the link above, I don't see GPS as an issue on the Motorola forums.
If I turn on network nav. and go into maps, my location is off by from two miles to forty miles. If I then turn on GPS it will correct my location within thirty second (time, that is). Turn off network nav., go back into maps and hit location and it corrects within 10-15 seconds using just GPS.
FWIW I just bought and downloaded Copilot live for North America ($5) Shut off data and ran on GPS -- it loaded very quickly. Of course it's pulling maps off the SD, but there was no lag in the GPS.
Same issue here.
Bought a defy (made in brazil) today and no gps (endomondo, gps test, gps status).
I already have a x10, and their gps always works.

When I first tried GPS on my phone it took so long to "kick in" I thought the phone was broken. Finally it did. I later got "GPS status" and it picks the satellites up right away. However, I believe you must have your google maps "Maps" turned on or the GPS won't work in the stock phone.
How much time your gps needed in the first time? I im trying right now.
In google maps: My location: Accurate to 70 meters (wireless method).
In endomondo: Locating satellites
In Gps Test: In view 1, In Use 0, Gps On (yellow), Accuracy (feet): 0
After about 1 hour, i am getting 2 sats in view on Gps test, but no one in use.
After hours, i am getting 2 sattelites in GPS Test (sometimes 3). But the color of the bars (SNR Color, according the documentation) is white. Not working...
On my xperia, i am getting 9 sattelites (yellow and green).
Make sure you're not on WiFi

My previous phone was an xperia x1 too, yes GPS was much much better. More than a issue with defy it looks like Android is not so brilliant in dealing with GPS.
I need long time to get my position fixed (could it be the lack of QuickGPS??), and it seems many apps can't correctly display the satellites while the device is searching for a fix.
It gets better if i have google maps app opened in background.
Finally got gps working.
I made a few things (not sure what work...)
- Factory reset
- Install a bunch of softwares (Endomondo, GPS Test, WisePilot, TrackerBooster)
What work (i think)
- Leave my phone with TrackerBooster and GPS Test turned on, in open space (a bench on a park) for about 45 minutes (airplane mode off, wifi on and connected, 3g on). In the early minutes, GPS Test only find a few satellites (4 or 5). Suddenly 10 satellites appear and change the color to yellow and green (it was white). Working!
Thanks all!
ps: Defy is better than X10. Even motoblur is better than TimeScape (IMOHO).

When i read "xperia" i thought about x1, anyway, i agree defy is better than xperia (them all) except for GPS. With my x1, in open spaces, i got 10-11 satellites in just 2 minutes (without QuickGPS) and it needed about 20 seconds when QuickGPS was working.
Hi, I'm really not sure what to make of this problem so maybe you can help me out pinpointing the problem so I can take care of it. I've observed several things and don't know how to connect the dots, or if there's any connection, so let me list what I've been seeing:
1 - I've got TomTom to use on my car.
2 - Worked wonderfully well on the first week or so. Fast to lock onto satellites (10 to 20 seconds), accurate and stable without loosing the lock.
3 - I've noticed from day one that it tends to to locate me a few meters back than what I'm actually am, so if I come about two streets very near one another, the turn on the correct one is a bit hard to to tell without looking at the map.
4 - A week ago, the phone started to take longer to lock my position and won't keep it, it often loses connection with the satellites.
5 - Also, the problem is a lot worse if I stop. It might be accurate while I'm driving over 50mph but, if I stop, the direction I'm facing is lost and then my location. It will place me within 50m to 100m of where I am, which could mean on another street. It has become useless for the slow paced city driving, with red lights and slow traffic.
6 - I haven't changed ROMs or anything major but I have downloaded a few apps, might have taken a few others out, the usual stuff... I'm using Android Revolution HD 31.2.
7 - I've noticed that a lot of times, in regular mobile use, the GPS icon shows up trying to locate my position, even with GPS off. Might be that I have accepted Google's location request or is embedded on some app. Don't know if this has any relation to the workings of navigation or with the timeframe the problem occurred.
8 - A final though... I've always had this problem with standalone GPS devices... They work fine for a few weeks/couple of months and then they seem to deteriorate, having a hard time to locate my position, maintaining a good connection, etc. I have no idea on why this is or if there's some sort of cache I should be cleaning.
Oh, and this happens regardless of the weather... overcasted, rainy days or clear skies, it's all the same.
So any thoughts on how to pinpoint the source of the problem so I can fix it?
Cheers!
Renato
Anyone?
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?
Hello,
I have this strange problem with the Samsung A50 given to me by my company (this to say that my possibilities to mess around "under the bonnet" are quite limited).
The first GPS fix from a "cold" start (that is, at reboot or after some hours from last use of an app using location) is EXTREMELY slow. It may take also 10 minutes or more, in full air and with good weather. If I control with the app GPS Status and Toolbox (or similar apps giving details on GPS sensors status) the phone "sees" a LOT of satellites, up to 20 or more, but none of them is fixed, they all are "yellow", and the location is not set.
When it finally makes it, one way or another, then the fix is stable and even if lost, it gets re-fixed soon in some seconds... For an hour or two.
Naturally this makes most app using GPS highly frustrating to use - Before running with Strava or navigating with Waze I have to wait 10-15 minutes for the GPS to fix! Google Maps is somehow an exception because it uses the Google "fused" location which, though not as accurate as GPS, allows nevertheless tp have an approx lpcation pretty quickly while the GPS makes its slooow fix.
But now the strangest thing: if I reboot the phone without SIM cards inside, the GPS works like a charm and fixes satellites on a matter pf 30 seconds max! Moreover, if I turn off the 4g on both SIM and then reboot the phone again, also it all works well. I tried multiple times and this cannot be a casual result. I also tried making a a full reset of the phone: the behavior is exactly the same. Seems like something in the 4G system causes some software conflict with GPS making it crappy.
Firmware is the latest (SH2 sept 2019).
Am I the only one? This looks to me definitely a software issue, not an hardware one, do you agree? Do any of you have commwnts, suggestions, ideas?
Thanks
Looks like I'm the only one with this issue?

And what about on wifi? Did you tried this?
The only thing that i can think of is on 4g probably it struggles to get agps data from the internet (probably cant connect to servers) but not trying to receive the data from the satellites themselves because it think it can get it from the internet. This is just wild guess.
I just tried getting GPS via cell data while taking a dump (inside the house), the GPS lock was instant in Sygic, also 15 satellites locked on.
I am having this same issue with an A50 I just purchased. I use GaiaGPS quite a lot and it works horribly on this phone. My tracks are a total mess. To the point that it is not usable. I will be returning the phone (if I can) if this issue is not resolved, as it is a key feature for me.
