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

mmh, where is my mistake? can't get gps lock with google maps, navigation and so on. car navigation is impossible. gps search is endless inhouse and outdoor
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?

It's little bit mystic...
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.

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.

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.

WiFi and Bluetooth won't turn on - Hardware defect or persist folder?

Hey all,
So I've been working on this for quite some hours now for two nights, but I'm done for and hope someone can give me clarity:
HTC One m9, running stock, latest update VDF Germany, Android 6.0.
Problem occured last week. I was using the phone quite extensively (yeah, tbh I was playing Pokemon Go... like a lot). With it being constantly on wifi/4g/GPS and all, charging it all the time, the battery also became quite warm.... And then while walking about it crashed and rebooted. I never had such a crash before tbh. After Reboot HTC Error Report even popped up and I also sent it. Then I found that the Bluetooth and Wifi Connections were off, which I usually both have activated all the time. And now I cannot turn them on anymore. No matter which shortcut is used. Wifi displays "error" after some minutes, while BT is just greyed out after triggering. Wifi Mac is showing with a 02:00:00:00:00 now as well.
So I did my research and performed quite some things, trying to get it fixed, because I am still not sure wether this is a Hardware or Software issue. A lot of people reported the issue at least for the wifi part. Less people reported it for both, wifi and BT, but I would guess that not too many people use BT regularly anyway. I found one person mentioning, that if both is not working it is most probably a hardware related issue. Which was my first thought exactly, thinking it overheated, something had gone loose internally and now the antenna is killed or at least not connected anymore.
As for the physical methods, I only tried the "whacking the back part of the device"-technique, which did not do anything. I haven't gone through "freezer" or "hair dryer" yet....
Some people were able to fix it via draining the battery and then restarting and draining again and what not.. but that all sounded weird to me.
I am still hoping it is software related so I went:
- Wifi Fix and Rescue App
- Unlock
- TWRP
- Root
- Reflashing stock
- numerous factory and network settings resets
Because I read about the /persist partition or folder and that it should contain wifi or mac address related info. Some guy had simply deleted those files and they were recreated upon reboot. But those files are not existing in my /persist folder (checked via Root Explorer - got the paid version) and I have Root - as stated above. Still that folder only lists:
\data
\display
\hlos_rfs
\lost+found
\rfs
\tee
I found a thread in google's cache of someone on how to recreate or fix that folder and contents, based on a nexus 5 however and that is probably not working on the HTC one m9 I was presuming.
So, what do you guys think?
Is there any way to get the wifi back to work? Would you say it even might be software related, looking at the persist partition/folder contents? Or am I totally wrong and the fact that BT AND Wifi are not working, rules everything else out and only leaves a Hardware Issue?
Looking forward to hearing your thoughts on this.
Thanks in advance!
- Arne

I'd bet a bollock its the hardware popped. Bluetooth and wifi are on the same board, probably the same rf chip. A local phone repair shop should ve able to fix it seeing as it's out of warranty.

why does my Head Unit loose timezone / Date & Time and country settings ?

since the last four weeks my head unit looses timezone / Date & Time and country settings!!
every time i reboot the device
The radio stations and other configurations don't get lost
Does someone know what causes this failure?
The wires for +12V Ground and so on are connected correctly

I update it manually.
I also tried the factory reset of the device.
But after i restarted the device the failure was the same

Another question is that did you update or install a custom ROM for it? If not I would suggest that as it might be outdated drivers may not be compatible. Basically its just like any other computer. Another suggestion would be to make sure the power connectors are tightly fitted if its not a plugplay.
Sent from my SM-N910P using Tapatalk

I installed the latest custom Rom from Malaysk.
It worked perfect for about 3 months
all power connectors are tightly fitted!

Same thing happened to me.

the only thing i can imagine how such problems can occur is a RAM problem
If the memory of the RAM loses it's information over a longer time period than we really have a big problem
I had an USB stick with this problem a longer time ago. In this case you can throw away the hardware!
The short solution is to delete all data and update the MCU
afterwards the bug is fixed and everything works fine again.
THE QUESTION IS ONLY----- HOW LONG??

How long did you use your device until it happened?

quite a while, year maybe. but i think the time messed up in december as well. I just messed with the settings so hopefully it is fixed.

Hi brownstein72 i could not find out how i can fix this problem in the settings. I tried everything what is configurable with time and date. But nothing worked. If you found a solution please give me a feedback. Greetings

Can't figure it out either. It seems to always revert to Moscow timezone, no matter what I do. I have even disabled all automatic date/time settings. As well, my bluetooth stopped auto-connecting to my phone around the same time. Strange, I have not changed anything, a bug with something to do with new year maybe? I rely on the auto connect for having tasker start the wifi hotspot... I am not on the latest Malaysk, I may update but don't want to, I had it all set up the way I like it.
Edit: This time problem also screws up the auto-dimming feature.

That's the same behaviour like on my machine. What i can say... it has nothing to do with the new year. I had this failure in the middle of december. The only way to get it running again is to wipe all data ;-(

I think I will update later today then, I see a new firmware from Malaysk was just released today.

On my unit the automatic time/zone according to GPS never worked.
The home time zone is grayed out and cannot be changed. First, on original soft and then on DSA's and original 2.97 MCU I had the home time zone set to Hong Kong.
A few days ago I updated soft to Booroondook's 5.1.1 + MCU to 2.98.
Home time zone is still grayed out, but now it's Moscow.
In both cases, time and zone never changed according to GPS (to Polish time, Eastern Europe, GMT+1). It was always the home time zone's time (Hong Kong something like GMT +12, Moscow: GMT+3). It's much better for me to have Moscow as a home time zone than Hong Kong, but still it's useless and I got to set the time manually. A complete fail with such a trivial and basic feature.
Anybody knows how to change the home time zone? Apparently it's a matter of either ROM or MCU (ROM probably, since Booroondook is located in Moscow, I suppose).

Hi ttoton, it's like i wrote last time.
The only possibility to fix this problem is to wipe all data and install the whole system new.
I did it last month and now everything works find.
I hope this bug will never occur

If you are root, check into the file build.prop in there you should see a line that looks like: persist.sys.timezone=Europe/Moscow
Modify that to whatever your android timezone is. That should do the trick. It worked for me.
I had the same problem as you, my time was always off. It basically remembers when the unit was shutoff . Than it took 10-20minutes for the right time to be updated (via GPS). I kinda solved it by changing the timezone line in build.prop .... and by forcing the GPS to update faster via an automation (app) script that wait for the car to boot and than automatically forces a GPS update by disabling the GPS than re-enabling it 3 seconds after. Now my time gets updated in 1min instead of 10+minutes. Something is up with the unit for sure but this is the best way I found it to make it work for me.

I did what you suggested. I found 3 files named build.prop in the system folder, so I made the change in every one of them. Changed the timezone to Europe/Warsaw.
Works like a charm, at last proper time with auto GPS time option. Updated the time within a second. Many Thanks again!

How to make my unit work in my car

Hello all,
I am desperately seeking some help.. I purchased this unit online May. 11 2018 and i have hardly been able to use it.
When i originally plugged it in it seems to be ok only the steering wheel button had some issues, either not working, or when i selected to change the track the menu also changed.. anyway after this i took it out just to make sure everything was connected correctly. and nothing was damaged. Then to fit it back and now none of the steering wheel buttons worked at all...
then one day the system would not even start up, I could see all the button light flash for a second and then nothing at all. I was finally told that i needed a new main chip to which they wanted $53 to which i blatantly said no! as this was under warranty. so after about a week they said ok but i will need to pay for the shipping, which i did reluctantly, but only because i wanted my unit working again.
So I received the new main chip and fitted it fine. I fitted the radio unit to the car and everything seemed to work perfectly, only no audio sound coming out at all. I can however here the beeping when i am pressing the menus etc on the unit, so there is some sound there.
The seller send me two MCU files to update my unit with, which i did, only now after these updates i don't have the image as full screen anymore and it is full of lines where the screen should be that's missing. The two files they sent me where: MTCE_GS_V2.89b and MTCE_GS_V2.88.
So now i have a unit in it with a new main chip and all looked good, except the audio sound not playing. i.e. MP2 through CD, USB or even radio. Plus now as well, that after the two updates above, the image is not showing full screen and in the blanks it is showing lines.
Please can someone help me as since May i this i have used this unit for 2 - 3 weeks max. Isudar, from where i bought the unit are also useless when it comes to support..
I just want it working again.... please help

You could try reading throught the thread about cross compatible MCUs. I see there are some GS specific notes in the first post. Maybe it will help.

Hi Kind3r,
Many thanks for pointing me to that thread, I am still reading through the posts as the original one makes some sense, i guess. But i am non the wiser what MCU i can or even should use. Being a bit of a noob, i am also a little afraid of putting something on that will make it worse I know how to upload the files, i just dont know what files I should be looking for or try.. right now for me the screen size is an issue and also not having any sound. When it worked it was such a lovely unit.
Could you possibly help guide me to where i can get these files and what files i should be looking for? And installation as simple as possible.
Pleeeeeeeeeeeeeease

Sorry, but I'm by no means an expert in this units, still waiting for mine to arrive. Nevertheless you should have taken note of your original MCU firmware, screen resolution, ram, android version and all the other settings found in the About device section. Without this information it is difficult to guess what is compatible with your unit.
I would first backup the MCU settings (via the Factory Settings menu). This you should do before any other atempts to install new firmware, change configuration etc. I think of this as a list of drivers from windows 98/XP times. This tells the unit what type of canbus is installed, if you have a CD/DVD, what physical buttons, if you have a reverse and side camera, tv tunner, TPMS etc. You can play around with the different settings but since they are so many you'll have a hard time getting it right.
Now the actual OS is more permissive. It communicates with all periferals via the MCU and enables/disables various features and apps based on what the MCU tells it is available. You can basically flash any OS you like and it should work just fine as long as the MCU has the propper firmware and configuration.
Now, in your case, I would try reflashing the MCU firmware that you got from your seller using the 'dmcu.ext' screen thing. It's a simple text file you put on the root of your SD card, with the firmware. It seems like the configured screen resolution is different than the display resolution (also the aspect ratio seems to be wierd). Try first with 'screen:3' (my guess it's an older PX3 unit) and if it does not work with 'screen:1'.
If that does not work, I would also apply the 'GS Configuration Settings file', but before doing that, take a note of all the settings in Factory Settings menu (as those defaults might mess with your canbus or other settings).
Please note that you are doing this at your own risk and I'm just trying to help based on the information I read in this forum. You should also read https://forum.xda-developers.com/wiki/Hui_Fei_Type and take a look in the repository https://yadi.sk/d/umCvHqCDzHccr for updated MCU firmware and OS for your device. If you are not confortable with all the information, I suggest you try to go to an auto repair shop that has a more skilled person who can troubleshoot your issue.

Thank you, this is making a lot more sense, i was not even aware that the dmcu.ext needed to be copied to the root location on the unit. So this has not been done. (i will try that again tomorrow, thank you).
I am now a little worried about saving the MCU settings... no one ever said i had to, but from what i have seen they seem to be the same as from before i upgraded it (fingers crossed now and worried)
The unit i have is a GS model or at least so the MCU updated tell me and what i received from the re-seller. I know its an Octa-core and PX5 with Android 8.0 and the screen resolution is 1024x600 32gb ROM.
So could the MCU in be a cause of me not hearing any of the audio? as you mentioned it communicates with differend peripherals? sory if it is a dumb question..
What unit have you ordered? I bet you are looking forward to it? I know i really liked mine, for the short time i could use it..
This is what i bought, i guess the look is just cosmetic to fit my car (Mercedes C class)

Then you should try with the file provided with 'screen:0'. Maybe you can see a screenshot of the About Device on the product page (btw, your link is not working for me), maybe it's a different MCU.

From what I read, yes, the audio is controlled by the MCU and not Android. Also it is possible that some or all settings are reset during the MCU update (some users reported this), this is why it is recommended to back them up. Playing around with the Factory Settings will not damage anything but it's a trial and error process that can take a lot of time as you have to reboot the unit for the changes to apply. You should try to ask you seller for the original factory settings file.

Oh you bet I'm looking forward replacing the decade old almost unusable Android 4.0.4 that came with my brand new expensive 2018 HR-V. Why manufacturers put such crappy units in new cars is out of my understanding. At least if it had Android Auto it could have been good for something, but nooo, it only has mirrorlink for which there are no apps.
Ok, enough rant, this is the model I ordered https://www.aliexpress.com/item/Car-1-din-radio-android-8-0-GPS-Navi-for-Honda-Vezel-HR-V-HRV-2014/32905561946.html?spm=a2g0s.9042311.0.0.121e4c4d03PwUR, after doing some research here on the forum. I think HotAudio/Dasaita have the best software support. I only wish they would also update the security patch level.

AL00 GPS not working

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.
