Has anyone managed to get their GPS Locking in Google Maps?
I've used QuickGPS to download the database and set Google Maps to use GPS but it never gets a fix.
When in TomTom it knows theres satalites about but doesn't connect to any.
Wondering if I have a duff.... anyone else?
How fast do you connect to satalites?
Have you been out of the house? Some houses really interferre with the connection.
Also, maybe there are some settings in the application you have to change? It should get a fix pretty quick. (first time from 10 sec tot 60, after that, below 10 sec).
So you have updated the quick GPS? Did you (after running tomtom and getting the update for the first time) do a soft reset?

Yeah, did a soft reset after I turned A-GPS on in Advanced Config program. Have tried it in work which usually gets a fix, but will try outdoors, just thought I'd ask the question first
why did you do it on in advanced config? maybe that's where it went wrong. Can't remember me having to put A-GPS on in advanced Config program.
I had the issue in google maps where I could not get a lock. I had to manually configure connectivity to com port 4 in settings.
After that it has worked perfectly. I cannot say if TomTom works or not as I am waiting for my ne SD card to be delivered.
I have however noticed that everytime I sync with active sync QuickGPS always moans it is out of date even thoguh I might have updated it about 1/2 an hour ago.
Its not a major issue as its connected to my PC and just downloads the data again. i'm just ignoring it.
Do not use A-gps.
I have my TP2 fixing with no problem without it: first fix in 55", then always under 10".
Try and use for first fix Quickgps.

Brilliant, turned off A-GPS and loaded TomTom 7.915/Google Maps, got a lock, even indoors.
Spot on, thanks for that!
Turn off A-GPS?
I keep seeing that to make the GPS work better, while also using QuickGPS, the A-GPS should be turned off?
How do I do this?
I have only had the Touch Pro2 for a few days, but have not been able to get a satellite lock in Google Maps even when standing outside away from many buildings.
If it would work better with A-GPS disabled, please tell me how to do this!
Thanks,

It should be turned off by default, I turned mine on using a program called Advanced Config.

Ok, thanks, just going to go try Google Maps again to see if I can get a lock. Maybe I just wasn't outside long enough, or far enough away from buildings last time.
Hopefully I can make GPS work soon
Ok, I just sat outside for about 20 minutes, in the middle of a field, away from any buildings, and was unable to get any GPS lock!
What is wrong here?
I have not touched the GPS Port settings in the control panel, but Google Maps only says Seeking Satellites (0) all the time.
If I do change Google Maps to use COM 4 Baud 4800, it gets worse and says Seeking Satellites (48037656) or some other equally stupid number! At least 0 makes sense, as there are not millions of GPS satellites, only about 20!
Please help, surely there is some way to make GPS work?
Thanks,

Hi all,
AGPS is not currently supported by any UK Networks, so should be turned off if in the UK.
Cheers,
Beasty
i think i ended up setting all mine to com0 but i think it wasn't working originally coz i was sitting in the car and it badly needs a wash (yes that bad). Just stuck it up by window for around 2 mins and it had 8 satellites but i've reset it so often since i last used the gps i wouldn't have been surprised with around 5 mins ... 20 on the other hand is a bit daft
Yeah, I'm beginning to wonder if there is something wrong with settings somewhere, as in 20 minutes outside it never indicated a single satellite in Google Maps.
I have downloaded the Advanced Configuration tool, and it says that A-GPS is Disabled, which is correct for the UK, so there is nothing to change here.
I have tried changing the Port settings, but I don't know what I should change it too. The Hardware GPS port is blank!
Getting close to giving up for the day, but I really want to get GPS working soon!

Ok, I had the same problems, have you updated Quick GPS? Are you using Google Maps?
If you go into settings and go to External GPS my GPS Program Port os COM4 next page GPS Hardware Port is none and Baud Rate is 4800.
Make sure settings are same and restart phone.
Have you installed anything since getting phone? Might be worth doing hard reset and trying is "out of the box" so to speak.
I could confirm the GPS is working and flawlessly! Much quicker than my old HTC P3600i and the locking is done in the CBD area!
I used the QuickGPS (download the latest update) and then using my GPS software called TechrificWay for Australian (it's a rebrand of NavNGo iGo MyWay 8)
Very happy ^^
(I need to set the TechrificWay application settings to find the GPS unit on COM4 though)
I actually spoke to HTC today and they think it's actually a fault with the hardware, possibly the internal antenna for the GPS is not connected properly.
Slightly annoying as I now need to send it back to get a replacement, or have it repaired, but good in that it's not a problem with me using it! There definitely is something wrong that I can't fix, I just can't wait to get one that works now!
I can get a lock, but get bad lag, and it wonders off course regularly. I wonder if it could be that the radio is not that great for GPS, as many other HTCs have suffered with GPS performance that has gotten better with certain flashed radios?
HTC gave me a generic response of "check these settings" (which were all as they should be in terms of com port and baud rate etc... So I think I'll have to call them if it keeps crapping out on me
(Fortunately) For me it turned out to be a genuine hardware fault causing the GPS to not work. I spoke to HTC and they believe I was the first in the UK to need to get a replacement due to a genuine hardware fault, which I guess is an honor (just a very annoying one!).
Even with the GPS not working for the week that I used it, I loved the handset, can't fault it, and can't wait until tomorrow when I should be receiving my brand new replacement, hopefully with working GPS and no faults!
Thanks for the suggestions here though, I needed to make sure it was a hardware fault before sending it back for a replacement.
I've tested three over 30km trips with Tom Tom 7 installed on the device.
Haven't lost a signal once. So it works fine here in Finland.

Guys,
According to this site, the problem with the GPS is the software Google Maps
Read this:
http://samsungi9000galaxys.com/galaxy-s-gps-review-sygic-gps-signal-and-gps-lock-times/
So it seems that using other Navigation software gives very good GPS performance.....
But how come using the GPS TEST software also shows that the GPS is loosing sattelites lock and erratic performance? I mean if the cause of the problem is the Google Map, testing the GPS receiver using GPS TEST should show good signal lock and stable reception isnt it?

It's a software setting: http://forum.xda-developers.com/showthread.php?p=7281059
Other android devices have the same problem with a wrong setting.
Its not true, I tried google maps, co-pilot and NDrive and all gave really, really crappy gps performance. Upgrading to JG5 firmware has improved things a lot but its still pretty unusable for me.
You know I was just about to post that I think the issue is with google maps and not the phone. If I apply the ntp europe fix my gps locks very quickly and stays locked to within 16 feet in gps test when driving about.within google maps navigation the performance remains as shocking. Arrrggghhh!

I wish i could help testing the phone with different GPS/navigation software to validate the analysis, but I already sold my phone last week out of desperation due to the the GPS problem and lag problem and phone freeze problem and signal drop problem when you hold it a certain way....
but i love the design, size of the screen, the thinness of the phone and the super amoled display.....
Ouch...
Why did you not return your phone instead? I have never had my SGS freeze and I have never been able to drop a call by cupping the antenna, altough the signal strength does go down, wich it will on ALL phones with built in antennas since you are shilding the antenna... ( NOT SAME AS IPHONE4 design flaw where you shortcircuit 2 different antennas and that part seems particulary hard to grasp for some on this forum....)
But, to get on subject again, the GPS has been bad, that is for sure and I hope this is a step in the right direction.
Its clear that testing the gps is waaay too subjective and subject to too many factors. Applications have no effect on the gps performance.

My GPS seems to be very hit and miss, but it has worked on the several occasions that I have really needed it (getting lost).
And widjaja why are you still shambling about this forum when you sold your phone? get back under your bridge.
Once again, another thread started because someone made one change, tested it and it worked, then posted how great it was. Trouble is since the GPS can work fine for days on end, and then not work for days on end, these supposed cures are pretty much all wrong.
The GPS doesnt work, and so far there hasnt been a public explaination as to why, just lots of guesswork, and no fix has been released (in any of the firmwares available today). It's coming, but its not here yet.

Seems some phones work some dont.On jf3 my gps was shocking but on jg5 it has always been spot on with google navigation and co pilot and ive tested it a lot in all weathers.It has never lost lock and is always bang on with position.I even tested google maps satalite view in the car parked next to a tree and it had me right next to the tree-within 10 feet accuracy.I dont change any settings just leave it on whatever settings jg5 uses.Im in england if that makes any difference
Found a fix on another forum and its been working pretty well for me.
Enter *#*#1472365#*#* in the dialer to enter GPS settings and change the following:
Application Settings:
Operation Mode - MS Based
Use SkyHook - ON
Accuracy - 30
SUPL/CP Settings :
Server - supl.google.com
Server Port - 7276
SUPL Secure Socket - OFF
I was having problems with 3G and WIFI with these settings at first, so I left Operation Mode on Standalone and Skyhook OFF. Works great now. Just tested it and got 9 satellite locks and 5 in use.

I'm in Hong Kong btw running local JF7 firmware. Hope this helps.
I'm almost convinced that most of the problems people are having is down to google maps. I'm not saying that tweaking the settings as people have, inc me, doesn't improve maters, but I believe there is an underlying compatibility issue between google maps and the galaxy which is making the issue seem worse than it is.
If I leave gps test running while driving I get at worst a lock down to 32 feet, speed is accurate and never lose lock even when on roads totally covered with big wet trees. It looks spot on.
Google maps navigation can't even get me in an accurate position when stationary, start driving and its bloody awful jumps all over the place and sometimes doesn't even move for 30 seconds after I've pulled away from a junction.
I've updated my supl settings to use google (manually edited the conf file, I don't use the hidden menu screen because even if you change nothing it makes changes to the conf file on exit, delete the file and reboot to refresh it) and updated my ntp settings to use europe.
In the jg5 rom google maps is built in, so I can't reinstall it or seem to be able to clear the cache to see if that helps in anyway.
It wouldn't surprise me if any gps fixed rom released by samsung contains a tweaked version of google maps that works.

I've been testing copilot 8 on my Desire G7 lately. I keep the GPS turned-off, when I'm not planning on using the navigation application and I activate it before i start the navigation app (copilot). At start up, it always takes the app 1-3mins or a longer time to determine it's current location.
Could anyone with off-line GPS experience tell me whether this kind of performance is within the normal boundry? A friend told me that leaving the GPS activated at all time will solve the problem. Is it true? If I do that will the GPS constantly sync satelite signals and causing it to wear out faster than usual?

if you keep your gps enabled, it will already have a satellite fix before you run your gps apps, so there will be no waiting time, the gps dosent constantly sync satellites, it just keeps a fix, it will use more battery, and it will also use the gps for "my location" but it isnt a noticeable battery drain!! try it, if you think it drains your battery you can always disable it

I'm glad to know that keeping the GPS activated will solve the problem. I'm not too worried about battery drain, since I can charge it frequently and the battery is at least replacable. My understanding is that if the GPS can maintain a "fix" on my current location, it should be synchronizing location data with satelites. My location varies throughout a day. It would mean to me that the "fix" on my location a GPS has is dynamic information. For a machine to maintain dynamic information, it must be processing some type of data at a particular frequency, which means that the GPS will be frequently operating. Is there anything wrong with my speculation?(I'm new to these stuff. Sorry if i'm wrong.)
My biggest concern is that whether keeping the GPS activated 24/7 will cause it to wear out at a abnormal rate. Have you had experience in taking such a practice with your mobile phone for a long period of time while your GPS hardwares still function at normal performance.
Thank you for helping me with my questions.
I've been using Co-pilot with my Desire ever since I got it (end of March) and GPS has always 'fixed' in less than 30 secs.
Recently I was trying out different radio ROMs (for non-GPS related issues) and there was one that took an awful long time to obtain a GPX fix. I switched to another one and all was fine again.
NB: My GPS is off and only switched on if and when an app requires it.

May I ask what rom/radio you've been using? Do you still remember which rom/radio didn't work quite well with your copilot? How often do you use your copilot?
I was having the same problem with the stock ROM & radio (2.2 latest OTA). Haven't tried yet with the new ROM (Leedroid 2.2d), but I was wondering if there was an Android application similar to QuickFix, Ephemeris or such on WinMo (downloading some satellite positioning data every few days to keep an approximate mapping of satellites, thus helping for a quick fix).
I also keep my GPS off unless an application requires it (e.g. navigation).

Well even with a stock ROM and radio (T-Mobile UK), which I had running for about 1.5 months, Co-Pilot still used to have a fast fix.
Later I upgraded to the earlier MCR ROMs (leaving the stock radio) and it was still fine.
After that I went to Froyo LeeDroid ROM (v2.1a) and upgraded the radio to meet minimum requirement (I forget what version it was). With this same ROM I am now using 32.48.00.32.
I can't remember what radio version didnt work well with GPS, but it was one that many threads stated it had a 'better battery life'.
I don't use Co-pilot that often but whenever I do, the fix is reasonably quick.
anybody can use gps on archos 101g9? can't get no sat fix. app gpstest does not show any satellite. is this a further bug in ics?

The same with my device at first.
I used the rooted ICS 4.0.5 and GPS Status from the market and started some experiments.
There'd been no response from the GPS part at all.
After some time i used a serial port api tool to directly connect to ttyO0.
Though the GPS part uses some hex protocol i had been able to get a response from the chip, but it was not human readable.
So this way i made sure there's no hardware damage on my UART interface or GPS chipset.
Afterwards i did some hard resets and checked settings of the UART by typing:
Code:
stty -F /dev/ttyO0
I started to run GPS Status again and also deleted my AGPS data by using the tools menu. Then i changed GPS Status setup to stay active and prevent device from sleep.
I took a while, but then the first satellite came in sight, still no fix.
Next day i did the same after some time more and more satellite where seen, but still no fix.
I restarted my device again to boot stock firmware.
Same again... more and more satellites became visible... but then... suddenly a fix. In fact it took very very long and i'm not very satisfied with the situation.
After i re-booted to rooted firmware again i was able to get a fix here as well.
The signal reception is still far from being nice though.
Try to get a fix with stock firmware first, then reboot and check again with rooted firmware.

Should be no problem with this setup.
AFAIK, these three settings address different services.
GPS should be set of course.

Nice thread, but people start to mix things up at some point.
Though the GPS and location service on Android OS is quite mystic, i'll try to concentrate on some facts.
Hardware:
- NL5550 chipset used on Archos Gen9 is up to date and not that bad
(merged into WL1283 chipset, see http://www.murata-ws.com/com7.htm)
- Due to hugh shielding areas, GPS reception is not the best with tablets (if compared to handsets).
- GPS antenna and position of the antenna seems to be problematic
Software:
- Firmware setup changed form HC to ICS
- size of the patch file for the chip had grown in ICS
(mabye they wanted to make thinks better, but they got worse)
So what could be done...
Hardware:
- I started searching for a better antenna to be placed in the housing
(e.g. helical/helix antenna)
- Place a HF-connector on the mainboard to use an external antenna
Software:
- Extract the firmware files from HC and try this setup for ICS
- try to find other devices based on the navilink chipset and compare their firmware setup
Basically GPS works on ICS and things in fact are not related to ICS itself.
Some firmware tweaks might be the cause of these issues.
The basic construcion of the hardware could have some side-effects on this as well.
Some people seem to have no trouble at all, so at least GPS reception is of course little bit depended on the weather and the area you live in.
I may post the HC firmware files here, if you like to try the HC setup on your device.

GPS lib loops
Hi,
I can ONLY get my GPS to lock on if the wifi and location services are enabled and working.
This is because, the gpslib tries to speed up the lock and position information by going out on the internet and firstly fetch the time from the main European ntp server.
Looking at the system logs, it appears to get into an infinite loop waiting for a time update.
Therefore my gps WILL NEVER WORK if actuated with NO wifi.
However..... If I start the GPS application, (I am using mmaps) with the wifi on and the locaation services on I get a good lock, with 10-12 satellites with the Archos INSIDE my house, within a few minutes. (There is nothing wrong with the sensitivity of the GPS engine!)
If I then stop the app and turn off the Wifi and location serves and restart the app it will get a lock in a few seconds and stay working until I power down the Archos.
This is OK apart from the problem that I want to use the Archos in my car with no wifi.
cheers

Yes, thanks for pointing at this.
Try to disable automatic time sync in time & date settings menu and check again.
You should definitely get a fix without setting the other location services or having wifi enabled all the time.

seems like a complicated science for a simple functionality
my older external sirf 3 receiver need only 5 minutes for sat fix after cold start (very cloudy!) and 10 up to 15 seconds in warm state. i wonder why the archos is much slower.
ok, i will give a new chance an try it again and again and again...and report later.

Assisted GPS !!!!!
Hi,
Unfortunately The Archos uses assisted GPS
I am not allowed to post links yet so see:- the wikipedia entry for assisted GPS
The Archos "might" use the Qualcomm chipset "GPSONE" , I am not sure but a lot of phone makers use it:-
see the wikipedia entry for GPSONE
Like I said in a previous post in the other place, I wish Android tablets were not still so mobile phone centric.

Archos uses TI NaviLink chipset. GPSONE is Qualcomm only and there's no Qualcomm chip inside our units.
TI NaviLink supports AGPS as well but it does not rely on that.
In other words even without assisted data you'll get a fix... sooner or later
Assisted GPS is always an option to get faster fix.
Did you try again with disabled automatic network time setting?

libgps loops!
Hi Scholbert
Thanks for correction re type of gps chip. Why I thought there was a GPSONE chip in the Archos was because the /etc/gps.conf uses the Qualcomm extra server site , see below.
However I still maintain there is an infinite loop in the ICS (or Archos modded) libgps. I have left the machine on for 8 hours and never got a lock without wifi.
I cannot post the /etc/gps.conf and the log here because I am too noob yet.
Instead have a look at my post here:-

I guess you're right... I made some further tests and must confirm, that i observed the same behaviour. This in fact is really annoying...
The GPS receiver receives satellite information (satellites can be "seen"), but there's no fix without beeing connected to the networks.
This is acceptable. We should contact the Archos developer's, especially user courville who has joined this forum for bug fixing.
He's an employee of Archos and one of the chief developer's, very friendly and helpful as well!

Had a view at this thread and read your posting.
If the described behaviour is compiled in the lib, we can't fix it ourselfs.
Archos needs to fix this problem by tweaking the library.
If it is related to a setup option, we might easily fix it at least on a rooted device using a customized image.
Had anyone tried the 4.0.6. firmware test release yet... maybe GPS got fixed as well.

Since GPS is integrated into wlan chip it may be necessary to power on wifi to power on also GPS part.

On 4.0.6 GPS works exactly the same.
Some observations (GPS Test)
-it takes quite a while to aquire lock even with "fresh" aGPS data
-lock is not stable- it likes to dissapear even if I don't move tablet
-catching new sattelites "unlocks" the lock
-accuracy seems poor- GPS Test didn't report anything less than 80 meters (Xperia Arc S in the same spot has <20m)
I get a lock within 10 seconds with my G9 inside my house. The accuracy has gotten down to under 4 meters. On my particular tablet, it works fantastic. I never had to clear AGPS data. I think this is luck of the draw. Some work great, some not.
My ASUS TF101 has all the issues you guys describe. Unreliable and slow. Most people with the TF101 do not have my issue.
My wife's LG Optimus One GPS works great, locks in under 20 seconds and never unlocks. My Samsung Galaxy Ace struggles to get a lock but can maintain it once lock is achieved.
All these devices are running different Android versions so I agree that it is not a software issue. I tend to believe it is the fact some get better build quality antennas than others making some of the same devices work better than their twins.
i have tested copilot on 3 different archos G9 80s. All have gotten a lock in my house. I have tested one while driving to work and it maintains the lock.
anybody want an archos 101g9 ?????
hi,
i'm back here after testing my 101 and i'm not really lucky
thanks to all here first. i pursued the discussion with interest.
my archos did not work with gps at all!. i checked with gpstest and gps status apps indoor and outdoor several hours/days. no satellites found! nothing, zeroooooooooooo. clear sky, no clouds and NO satellites. i'm alone in the universe
what i did:
- device cold start (many times)
- switching on/off date and time from ntp server
- wifi on/off
- google location service on/off
no idea what happen. this is not my first archos. my older g8 had broken usb ports and was changed 2 times. the g9 freezes very often in cpu state "hotplug", run stable only with half speed and gps don't work. why gps need an internet connection?? i have no 3g stick in my tablet and no wifi in my car. yes, i can connect my phone with wifi tethering but sorry, that's not what i have planned. puuh archos, what do you think what customers tolerate. i love android, but the next tablet should be better an ipad
seems, there is a defect. how can i check my hardware before i put it in the trash?
thanks,
4carlos
by the way, my htc legend with froyo works great. it beams my to every point i wish!
Sorry to hear all you guys are having such problems with gps lock.
I have an original 8gb 9g classic. I have taken it through Honeycomb and up to the last ICS update. I have rooted it, over-clocked it and it has taken everything that I have thrown at it!
In every case, the gps has been first class. Using gpsstatus from the market, it locks on to 9 sats from inside my house within 30 seconds.
It was originally set to europe.pool in the gps.cfg file and I got a good lock with that. When I changed to rooted custom fw, I downloaded fasterfix from the market and used it to change the gps.cfg to uk.pool. This speeded up the lock and increased the number of sats to 11.
One thing that may help, has anyone tried toggling airplane mode on then off again. Whenever I install a new rom, on phone or tablet, I reboot the system at
least twice after setup and then toggle airplane on/off. This was an instruction in some roms that had wifi issues and I now do it as a matter of course.
It may be worth a try.
I use Co pilot live as satnav and it has never failed to lock on within seconds of being set up.
GPS on G9 still behaves strange...
First of all, thanks for posting your observations.
The GPS issue remains little mystic though

I just got a fix within a minute, yesterday it was a no go!
The device actually needed a reboot before. What is responsible for this locking???
I got the fix by...
- deleting the AGPS data in the settings menu of GPStool
- setting the data update interval to never
- unchecked set system time from server in the device settings
- Wifi and 3G were disabled as well
So it's possible to get satelite fix without network connection.
But something may lock the interface. Afterwards it seems to be impossible to get a fix again... at least things get worse.
BTW, GPStool and the AGPS "framework" of the G9 use definitely different data bases for the assisted data. Maybe this causes locks as well...
So from what i can tell... disabling the AGPS function in GPStool definitely helped to get a fix.

O.k. might try fasterfix... though it seems to set the timeserver to another domain... What else does it do?
We need more understanding of the mechanism in general.
Did anyone try the Gingerbread setup on ICS yet?
I may post the files here...

Maybe it's worth a try but maybe it won't help anything.
As far as i can tell, a reboot certainly fixes some kind of lock on the interface.
But as long as we always guess there will be no improvement, nor we'll find the real reason for the missbehaviour.

I can't find GPStool in the market - is that the correct name?
I would like to try your procedure to find out if my GPS is working at all.
Thx.
Don.

i guess :
GPS Status & Toolbox (author EclipSim, can delete agps data)
also nice
GPS Test (author Chartcross Limited)
GPS Status (author espresso3389, nice graphical tool but only portrait mode)
btw.
upgrade to firmware 4.06 (fix for increasing gps stability) did not help in my case. only my problem has more stability now. still no satellites in sight. my htc legend shows a minimum of 5 satellites with the tools from above at my location (indoor) but still nothing with my archos. disappointing.
the better way is to check the gps functionality before rooting the tablet (loosing guarantee!). seems a weak point of tablet.
i'm searching for an external bt mouse. any recommendation? the mouse should be bought in germany.
I found a new rom for the XZ1 Compact.
Until now only a few regions are available. Probably the June patch.

Yep. None for Customized DE just yet.
It also comes a little bit late. Am I right?
The xz1c was released on 7.31.17 and I wonder if we will get more security updates after the two years after the release date.
Flash this yesterday using the FTF found here: https://xperiafirmware.com/sony-xperia-xz1-compact/
Can't really see any difference so far, but also no issues with it
Seems to have improved GPS performance on my end. Connection is still a bit weak, but it catches more satellites and doesn't lose tracking suddenly.
The GPS bug is still there and things have gotten even worse. I use a lot of GPS (Waze) and during the weekend I experienced that three times... I just dont get it how Sony cannot resolve that issue (((

I came across this problem on my XZ1c, but I found a fix.
Go into airplane mode and make sure GPS is disabled.
Settings\Apps & notifications\App info - find Maps
Force stop - Storage - Clear cache - Clear data
Restart phone
Enable GPS, airplane mode off.
If that doesn't work use the following service settings number to go in the gps settings :
on your phone keypad dial *#*#7378423#*#*
Go into service tests, select gps then purge test data
reboot

what GPS bug is this? I can't say that I've noticed anything off when using Google Maps for directions.

Usually it happens when I finish using Waze or Google Maps (or any GPS driving app) and after a while I start it again and then it just does not find any satellites. Sometimes after a few minutes its back but sometimes even an hour waiting does not help nor restart nor anything you can think of. And of course it usually happens when you are in hurry It really p....s me off when thing does not work as they should be, especially when you have no time to waist
Well, everything worked fine couple of days and then I started losing GPS again. Seems that purging test data from service menu is the best solution for this bug, sometimes I dont even have to reboot. Still that is very annoying and one more reason not to buy Sony anymore... zero customer support, all this nonsense preventing people to root their phone, bug after bug that dont get fixed etc. They just don't care about anything after you've made your purchase. I've been loyal customer with 3 different phones for 7 years but seems that current XZ1c is the last phone for me that bears the Sony label. Shame on you Sony.

Can you please upload it on mega or drive if possible
Here you are:

Has anyone experienced loosing GPS signal after a 1-2-3 hours of Google Maps ? It may be like the device is overheating. GPS is back usually after resetting.
