gps not working after the forced mango update

There's a problem with gps on my phone Samsung FOCUS ,Gps is not working even in the open sky, tried several app like -> gpsinfo,wingps and others like RunKeeper,RunSat etc
Phone is Dev unlocked as well as Interop Unlocked with internet sharing enabled.
The update was done using forced method.Updated from stock firmware->7008->7032->7043->7720.68.
Versions ->
Diag app-> 0103
firnware - 2103.11.8.1
hardware rev. no. - 3.1.0.7
Bootloader ver. - 5.8.0.2
radio software ver. - 0.0.0.3
Please help?

Microsoft released a statement saying they don't blame people or doing the forced update... it doesn't do anything bad to the phone so I don't think that's the issue. You might want to try rolling it back to nodo, checking your gps and then reloading mango. if still no go. Hardware issue maybe??

Issue solved,thanks anyway

So, what was the problem?

Don't know, flashed mango again.That's it.
Gps locked in under 10 sec inside the room.

Hmm. My GPS will find my location fine but getting directions is terribly slow now and turn-by-turn will always just say "can't connect to satellites." Now I'm wondering if a rollback and updating again to Mango will fix this.

I'm on official Mango on an AT&T Focus (and I didn't force the update), and I'm having problems just like the previous posters with GPS fixes and 'can't connect to satellite' errors when trying to get directions.
I found a solution by going into another application that uses GPS, getting a GPS fix in there, then going back into the maps. The program I use is "GPS & GPX Logger." After that finds the satellites, the maps work as they should.
For background info, my phone went from NoDO->Mango Beta 2 (7661)->Mango Beta 2 Refresh (7712)->Unforced official Mango including "Samsung Update"

I tried the turn-by-turn again this morning and it actually worked. This is the first time it has since updating last wk. I didn't change a thing, so I have no idea why it work suddenly.

GPS works on Samsung Focus even after Tango update
I own samsung focus 1.3 (AT&T). I purchased it in the beginning of Sep. 2012 (quite late). As soon as I got the phone, I connected it to Zune for updates. After having updated to 7.10.7720.68, I started using the phone. The GPS did not work. I then updated it to 7.10.8773.98 with the hope that updates may make GPS working. I tried all possible tricks available on XDA as well as other forums. I tried following tricks with various permutation & combination:
(i) Pulling out the battery for 30 minutes.
(ii) Changing the MOLR CP/UP setting in GPS diagnostic to UP and CP (one by one),
(iii) Rebooting the phone with location off & again rebotting with location on
(iv) Apps like GPS info & others
& few more which I do not recall now.
After having tried for about a month, I reverted back to original OS version 7.0.7004.0 just to ascertain the availability/ functionality of GPS hardware as on some of the forums I read that their GPS stopped working after No-Do updates. The GPS did not work even after trying all above tricks on 7.0.7004.0 version of OS.
Finally I accepted my GPS to be faulty or not being there and again updated to latest OS version.
One day I read on some forum that putting off the location service & then switching on makes GPS working. Wow, I tried it today, IT WORKED. On bing map it locked, initially with a bigger circle & then reducing down to a dot. In areas covered with thick trees or high-rise buildings, the circle used to become bigger but again in clear sky area it used to reduce down to dot. I am keeping my fingers crossed. Let me observe for some more days to ascertain that this trick actually works.
Those who have not been able to make their GPS working with other tricks, please try this & let us have your feedback on this forum/ thread.

GPS not reliable
In continuation to my previous post, the working of GPS is not reliable. It sometimes works very fine & some times doesn't work at all during the entire journey of 15 Km. You cannot depend on this GPS for navigational aid. It appears to be some software issue. But anyway, I am happy that my GPS is not faulty. Hoping for some fix in future which will make GPS work reliably.

GPS working perfectly for me with my Nokia 800 with Nokia Drive.
Some cars have some sort of coating on the windscreen which sometimes blocks GPS, although I wouldn't expect that to be on US cars.

The issue is not related with car glasses as I have tried a lot in clear sky on foot. The issue seems to be specific to Samsung focus drivers.

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?

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.

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 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.

Location inaccurate despite 10+ satellite locks

Hello friends,
since June 19th I'm having severe issues with location accuracy on my OP3. I'm running the most recent sultan Lineage 14.1 build from June 15th, flashed it on June 17th. On 17th and 18th location was fine, since then it became inaccurate (I'm a daily ingress player). I did not make any changes to phone settings or setup between flashing the rom and the location service going bad. Then I went through different firmware files from https://forum.xda-developers.com/oneplus-3/how-to/radio-modem-collection-flashable-zips-t3468628 (Open Beta 16 through 18, 4.1.6 builds) without any improvement. Also cleared cache, reverted to the previous sultan build, all to no avail.
I have all possible location services enabled and I'm outside, consistently maintaining a lock with about 6 to 8 GPS satellites and 2 to 4 GLONASS satellites according to "GPS Status and Toolbox" (https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2&hl=de). I tried re-downloading aGPS data through that app as well as re-calibrating everything it allowed me to but even then and with those 10+ satellites, I'm seeing location error of +-70m or even more. Also, I'm moving around in an area with buildings not higher than 2 floors or even in small parks.
In Ingress, I'm drifting from one side of the street to the other, wrongly going into side alleys, not moving at all for several minutes, and so on. Before June 19th I could effortlessly navigate through the game with pretty much perfect accuracy, now I have problems accessing portals I'm standing on top of for 2+ minutes.
I'll attach some screenshots of GPS Status app from today. You can see errors of 30+ and 70+ meters with 14 satellites available. When taking those screenshots, Ingress was basically unplayable. I'd be grateful for any input on how to tackle this issue.

Does the same thing happens if you use the previous build? If the answer is yes, then there's something wrong with the June 15th build.
You can also try with the latest OxygenOS stable or official LineageOS to see if it's a ROM or hardware problem.

Thank you both for your input!

I reverted to the previous build but the issue remains. I plan on eventually trying OxygenOS if I can't find another solution. This will have to wait until next week though. Not enough spare time right now.

I think that's the same thing that "GPS Status and Toolbox" does. Still, I'll give it a shot and test during lunch break.

I used to get erratic gps info when i was near high tension electric line...

HI,
i've also bad signal GPS but with FASTERGPS ( https://play.google.com/store/apps/details?id=org.fastergps&hl=fr) i've solved the problem.

As I've been living and playing in the area for years, I doubt this issue is about external influences

The app you recommended doesn't seem to be able to change the gps.conf file on my phone. I made the NTP server change manually, though. Sadly, I can't see any improvement.
I just don't get what's wrong. It has to be something about my phone or how it processes the data. I know that GPS has some leeway, but I have a lock 12 satellites and only 70m accuracy. I can't comprehend how this is even possible. :crying:

--> You must be to root. This soft modify without error my 'gps.conf'.
Despite an improvement, I remain decadent of the quality of the GPS. I do Geocaching and I can not rely 100% on my position (20M Margin with 20/25 Sat).
Here is a link from the ONEPLUS forum that talks about this: https://forums.oneplus.net/threads/fix-the-horrible-gps.465819/
OOS 4.1.5 Beta have good result with GPS: http://downloads.oneplus.net/oneplus-3/oneplus_3_oxygenos_openbeta_15/
EDIT : I Forgot --> test to activate only hardware GPS without WIFI, BT, data.... Only GPS --> Go to setting - location.

The beter isue is to modify the GPS.Conf manualy, and fastergps make this change automaticaly just selecting continent and land.

I have the same issue with beta18.
If I select location only by gps it works perfect, but if I select high precision (wifi+network+gps) it see satellites but never get a fix.

Yes, same problem. I use only GPS and work good.

Interesting, I have been having the exact same problem and first noticed it with Ingress. Using a OnePlus 3T running open beta 18 Will try changing GPS mode to device only and see how that goes. I'm sure this only started a week or two ago, it worked well for a while after flashing open beta 18.

Sorry for abandoing my thread for so long. Been on vacation. While on the highway, GPS suddenly died completely, had to take a break to reboot the phone.
After that, I reflashed opengapps because I was bored one evening. Like two days later, it felt like it improved a bit. Playing ingress got easier again, but it's still... "wonky" up to this day, which it wasn't before.
I'll try GPS only mode asap.

i was on AOSPA 7.2 when this issue started, switched over to OOS beta 19 (freedomOS), and now updated to OOS beta 20 (freedomOS), and still this issue persists.
already tried clearing AGPS data once, has anyone figured out a permanent fix?

+1
ALL other GPS apps work.
Just Ingress is fussy.
P.S. Seems like Ingress has a slalom algorithm that manages to navigate around portals and avoiding them for hacks/capture...
Waze, Google Maps, etc. - are SMACK on location.
I'd like Ingress to constantly update it's location, even when screen is off.
Plus, force-keep internet connection alive.

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.
