AL00 GPS not working - Huawei Mate 20 X Questions & Answers

Got the phone from Wonda in December. Have now just notice that GPS is not working. Haven't attempted to use GPS before so don't know if this is a new problem or not.
Have downloaded several GPS tools but none have helped. One tool (GPS status) does not even show any satellites.
I have previously removed some apps using adb following guides given in these blogs but have not seen any reports of similar problems. So at this stage I'm not sure if this is a hardware or software issue.
Have carefully checked all settings and can't see anything that would stop the GPS function. But, looking on the web I came across an image of the "location access" settings screen. This shows additional location mode settings which includes GPS but these options do not appear in my phone settings? So maybe that is the issue.
Have included a screen shot of my settings page and a copy of the web page image that I found.
Can someone please confirm if Location mode is or is not included in Location access.

what is your phone version number?Is it after the upgrade?

Its an EVR-AL00 and had all updates installed.
I'm not sure what/when affected the GPS. It may not have been working since I took delivery from Wonda.
Did a factory reset today and GPS is now working fine :good: and now I know that the screen shot that I took of my phone location access settings is the standard for EMUI 9 (GPS is not shown as additional location mode settings).
So it will remain a mystery but would edit the title to show it is 'solved' - if I knew how

Is there metal in your cell phone case?Or there are other magnetic objects around it.

No. Thought of that at the time. Took it out of its case but still didnt work. Not even outside the house. Only a hard reset fixed it. Now it works in the case, in rhe house, everywhere ?

How you know not work? You can't choose between gps and wifi net?

The clue was in my first post: Have downloaded several GPS tools but none have helped. One tool (GPS status) does not even show any satellites.

A little different question
How to control now do I use gps or just nets?
Thanks

Maybe there was something wrong with the software at that time.I'm glad it's back to normal.

GPS Lock, anyone with issues?

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.

Motorola Defy GPS Problem Solved - 14 April 2013

First fix will take 3 minutes in open sky.
Use GPS TEST in open sky.
Please give your feedback on this thread . Thanks
If you Like Click Thanks ------>
i'll try this on CM7 to see if the problem is solved...as the most problems are on CM7(not stock)
updated first post...
popcorn1122 said:
In CM7 & MIUI... this line is removed... so that may be creating the problem.
The initial ephemeris data is downloaded by a active gprs connection. Many people instantly start the gps application to check the satellite fixes after they install a ROM. During a new setup of ROM, the gprs is over burdened by lot of sync... hence if the ephemeris data is not downloaded on time... and they feel that the GPS is not working.
Click to expand...
Click to collapse
i know that location.cfg was altered on cm7/miui hence learn_store.bin wasn't there anymore
i've changed gpsconfig.xml and location.cfg with stock ones and modified that line.
I'll test gps navigation and report how/if changed
edit: i rather go for an accurate psitioning than instant gps fix
Great work there..kudos man!! Is 40402 the proxy port no. for Airtel GPRS? I'm kinda lost on what to put for TATA Docomo as there aren't any port nos. in the settings..
Always try the experiments in open sky
Always use GPS & Location on
I did all that. From your numbers -before reading your last post- I figured out that it was MCC/MNC #s; so mine is: China Mobile (46002)... --> the "(46002)" part is required isn't it?
After a few quick tests with Locus Pro, I can't really tell if anything is different. If I turn on wifi (agps) the lock is real quick, the reported accuracy is less then 10m, but in reality the position is always off by 50-150m...pretty much like before the tweaks.
But, like I already wrote on the cm7 thread before, gps is always not so accurate in dense urban areas filled with cellphone transmission towers, wifi access points, tall buildings and what not...
So I'll leave all this as it is now and keep monitoring.. hopefully, I'll be able to squeeze in a MTB ride sometimes soon...
Thanks for sharing all this anyway.. Cheers

Is true that in dense urban areas gps is not so accurate but the annyoing thing is that on stock motorola rom the positioning was spot on...now not so good:-s i wonder why? we still use same (proprietary) files like in stock rom
popcorn1122 said:
404 is MCC and 92 is MNC... but you need not touch those values....
Just do this:
In Menu-->Setting-->Wireless & Networks-->Mobile Networks-->Access Point Names-->Select the Profile you are using-->Click Name--> In that input box whatever you see is what you have to write in the location.cfg file of /system/etc
Click to expand...

I had a thought it might be MCC/MNC but still wanted to be sure. My MCC is 405 and MNC is 03..so mine should be TATA DOCOMO INTERNET (40503) since my apn is TATA.DOCOMO.INTERNET. Hope it works. Thanks again.
so this fix is for stock roms only?
This fix is for any motorola defy using stock or CM7 or CM9 or ICS roms
As a defy user, I also found that the gps is not working, after I have rooted it long time ago. I have just tried to fix it using the method provided, but after doing what you ask me to do, the matter gets worse! Originally a few satalittes could be searched when I ran the GPS test app, but now there is no satalitte that can be searched... the gps simply is out of service.. I am a Hong Kong resident. Could anyone kindly provide me with a way out? thanks!
No improvement
Hey guys, thanks so much for the advice.
I'm on T-Mobile US, using CM7.1 jordan.
I updated the location.cfg file as you suggested. I did not originally have the Default line in it so I just added it. I deleted the files recommended and copy the gps.jordan.so file, calibrated compass and rebooted.
Is there anything I check to see that I did this right? Any info I can provide for someone to check my work? Thanks again.
Does not work for me
followed all the steps by the second method, but still my phone reboot when i use GPS and WIFI :-(
using defy mb525 with the default rom (rooted)
Guys I have updated the first post with a new set of files for making Motorola Defy GPS work better. Please comment here if you find it better and if you have any suggestions.
popcorn1122 said:
To test GPS
Always "Use GPS satellites" in menu-->settings->Location & Security.
Always "Enable Use wireless networks" in menu-->settings->Location & Security.
Always use automatic in data and time setting.
Always perform the testing near a open window where you and your defy can see sky.
After installing all the above.... go to setting...privacy... reset and it will reboot. Wait for 5 minutes after you enter the initial google registration login. It is assumed that you have a valid gprs APN or wifi working during this process.

Thanks for this research work! I am really happy, than someone cares about this. I am also suffered from the problem, that I can't get a fast fix, if the download of the latest AGPS data is 6hours or more ago.
So I exactly did what you suggested.
A few questions to that.
1) I found that my /data/location/gpscmd file is empty (0 byte) - is there something wrong in myy system?
2) The 2nd part of your lge.cert docu is not clear to me. How can I install lge.cert ? This is rwrwrw, not x. And even if it is executable I don't know how to execute it (using root browser)
3) about location.cfg: I remember that some time ago the moto-servers failed and there was are recommendation to exchange to google servers... But this might be obsolete now - this is just a hint.
4) the gps..jordan.so file has same size before. I didn't check it binary. Is this the same lib?
5) I don't understand why it is necessary to use the setting/location/use wireless networks. I don't like the idea to involve google here - and this is only helpful, if I am online.
Now my observations (short term).
Initial start with wifi on (to download AGPS data):
My impression is, that time to fix is longer and numbers of sats are smaller than before. Might this have to deal with some initial setting which is for you maybe ASIA but has for me to be Europe?
After 2h the fix was quite fast (40s). it behaves a bit different than before. Originally I have a few sats fast, but to fix them takes some time. Currently in the first 20s nothing is to see, but than the fix is rather fast.
Thanks and best regards!

Do you know this thread (http://forum.xda-developers.com/showpost.php?p=24014309&postcount=1) with downloading and usage of an lto file? Is this used in your approach too?

Wireless network are part of aGPS as the cell towers also provide the location info if your carrier has made proper settings on cell towers based on its location.

GPS on Archos 101G9

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?
running rooted ics 4.05 for sde (surdu_petru).
I have a Archos 80(same hardware though) and my GPS works fine on firmware 4.0.5
And if I may say so wow is it good, I get a GPS lock inside my house after about 20-30 seconds

settings location + security:
"use wireless networks = off"
"use gps satellites = on"
"use location for google search = off"
edit:
found this in another forum
http://www.forum.archosfans.com/viewtopic.php?f=85&t=64272
can anybody confirm?
Mine works great. I'm using 80g9. My archos is now my traveling/adventure teblet. I have two and like the screen size for jps etc in my jeep?

Hey guys,
last week i also thought about open up a thread related to GPS issues on the Gen9 series, because i had some trouble to get a fix as well.
I'm using an Archos 80 G9.

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.

O.k. this is also very helpful information. I must admit that sensitivity is not that bad, but could be further improved... that's why i also talked about hardware in my last post.

big thanks for descriptions!
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.
cheers

Please refer to my post above:
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)

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:-

Yeah no problem, i'm a hardware addict... so if you need some info about the chips of G9 ask me

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.

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.

[Q] GPS drop out

Brand new Huawei P6 ... GPS horrible!!! .. takes ages to lock on, and then when it does [sometimes] cannot use NAV for any reliable length of time as GPS drops out and stays out .... oh, some times it might come back on again .. but long after the waypoint has been passed making the navigation service completely useless ....
Have upgraded to B111 via the GUI on the phone. Android 4.2.2 but ... no joy.
I have been trying to find a reason .. thought maybe it was app related and that myabe gmaps or nav contributing to the issue ... so installed some GPS helper apps to try and troubleshoot the issue, but they seem to be affected by the same problem ...
I am annoyed and frustrated as i rely heavily on GPS ... the Ascend G600 i had previously worked flawlessly!!!
Has anybody got any clues on this ... :crying:
Try TopNTP. Play around with the settings. One of them might speed up lock on tremendously.
My fastest lock on was 7 seconds, even with GPS cold start. Inside my apartment!

Thnx for the suggestion UpUp ... but unfort no joy either with TopNTP.
So did a factory reset and first up Google Maps Navigation finds my location and draws the route to destination .. even get a voice announcement to send me on my journey ... BUT from that point on the GPS icon continually flashes with a notification "Searching for GPS ..." that continues ad infinitum with the map locked on my initial position ... suddenly it might jump to some totally inaccurate location ... and then finally the voice announces Lost GPS Connection ...
However, on one occassion .. after 'searching for location' for about 15 mins .. all of a sudden my location is pinned as accurate and the navigation went along smoothly for about 3 klm ... then "Lost GPS Connection" again ... never to return!!
I have tried TopNTP, GPS Status & Fix, GPS Fix, Essential GPS ecc ... but no joy!!
I cannot believe just how crappy the Google Maps Navigation is on this highly regarded HUAWEI phone is!!!
Surely i cant be the ONLY one with this gripe??? But at this stage i can find very little on the net about it ... very frustrating!!
PS: At one stage i got GPS Status & Fix to lock on in smart time 7 seconds with maybe 6 out of 9 sats .. but then when i loaded Google Maps Navigation, even GPS Status & Fix could no longer get a fix!!!
Does anybody know if there is an issue with the software Google Maps Navigation????
Help IS neeeeded .. thnx!
Mmm... wonder if your P6's GPS is defective. You should get service since it's new.
I read a lot about slow lock-on, but it is a common complaint on most brand names. Nothing can't be remedied by TopNTP or GPS Fix.

Okay .. fair call .. i was starting to think the same way due to lack of similar cases returned via Google search.
Spoke to their local service centre ... after describing the issue was promptly told to return the phone for servicing, even though i pressed for a firmware upgrade! Even though they would not admit it, sounds like they believed it to be a hardware issue.
So have to wait 2-3 days for an email to arrange pickup instructions .. then 2-3 weeks for resolution!!! But i have no option, save throw it in the bin and try another brand/model ... obviously at my expense! .. wtf ... will just have to be patient.
Will advise on outcome.
Thnx
This is what I did,
go to dialer, press
*#*#2846579159#*#* then go to item5, background setting, next to AGPS settings, change the positioning method to autonomous, on service location, change to supl.google.com. This will speed up the GPS lock. I am using ASIA phone, not sure if your firmware is similar. Good luck.

Alternatively, if your phone is rooted, you can replace the gps.conf file under the System\etc\ with the one I am using now.
I actually got it from the LG Flex and played around with it. It works perfactly. When you have Internet on, it fix the SAT really quick.
You need the Root Explorer to change the permission to overwrite or delete.

Can I use this on Europe version of the phone?
Edit: OK, I answer myself. The posted gps.conf file works great on my phone (EU/CZ) and at the moment I get fix in a few seconds.

[New Firmware] 47.2.A.10.80

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

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.

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.
