[Q] Location service at switched-off screen - Windows Phone 7 Q&A, Help & Troubleshooting

Hi,
I have a problem using my sports app "Runtastic". Every time when I start an activity and switch off the screen after a minute or so I get the message that GPS signal got lost. When I switch on the screen then I have immediatelly a GPS signal. In the settings of "Runtastic" is a switch "carry on application at active lockscreen". This is activated but seemes not to work.
Can it be that at WP7 the location service (GPS) will be stopped after some time when screen is switched off? If yes, does anybody know a tweak to disable it?
Thanks and best regards

mhh, that's strange. maybe you can disable your lockscreen.
here the registry twek
[HKEY_LOCAL_MACHINE\System\State]
"Lock"=dword:1

Maybe it is a problem of the "Runtastic" app. I tried with disabled lockscreen. After switching off the screen the GPS signal got lost again.

Runtastic appears to run okay for me with the lock screen up(HTC SparkW), but this could be a phone specific issue. I used to have a very similar problem with gMaps Pro, but it was eventually corrected when brought to the developers attention. I would contact the developers and let them know that your model phone is having an issue.
This app doesn't have any settings under Settings=>Slide to Applications=>background task=>Advance.. and I know after gMap's Pro was updated, I went here and change some settings and it would keep running afterwards.. but.. the dev had to implement a fix on their end first.

Thanks for reply. I have a HTC HD2 with Pdaimatejam 7.3 custom ROM. I will check other sports programs like Endomondo or Sports Tracker to see if it is related to the Runtastic program or to my phone.

GPS when phone turned off ?

Hi all,
I've posted this in the Iolite/Cruise 09 section as well. I'm posting here so there's a better chance of answering my question.
I just got my Cruise 09 delivered last week, it replaced an Eten M600 which finally died a month ago !!
I'm really happy so far, it could do with one or two more hardware buttons , but it's not really a problem.
I've been trying out TomTom , and bought the Europe maps, it works perfectly so far.
I have a question I hope someone can answer for me - Is it possible to turn off the phone and still use the GPS ? When I turn the phone off and try to use TomTom, I have a message on screen "All connections are disabled (Flight mode) "
Is there a way around this ?
I will be driving abroad soon and don't want to leave my phone on all of the time.
Thanks
you can turn it off but you can prob toggle the screen so you save a bit of power
that way
thing is when suspented the phones disable the sd interface to save power
and thats where most people keep their maps
It's a design flaw of TomTom. Other GPS apps work in flight mode though. You can turn the phone off but leave the wifi and/or bluetooth on. Driving with the phone off seems like an unnecessary/bad idea. Any good reason for it?
Hi ,
Thanks for the replies.

The reason I wanted to operate Tomtom without the phone turned on is because when I go away on holidays I usually turn my phone off. After all , the whole idea is to get away from it all and try to relax, not be answering the phone all the time.
I'm planning on driving around Scotland, and will be using the GPS on my new Cruise.
I've just been experimenting with my phone. If I have wifi enabled and the gsm off, Tomtom says flight mode enabled.
If I have Bluetooth enabled but wifi and gsm off , Tomtom works !
I also just got an email response from HTC, as follows --

I just installed the app..I'll give it a whirl tomorrow outside. I did a test recording indoors and I noticed something weird.. the video doesn't show what I'm looking at, it shows everything rotated 90 degrees.But the video that gets uploaded to the site looks fine.
edit: Have you checked Qik? They're kinda your competition..they don't emphasis location as much, but it's an option there too.
looks interesting but what would you need it for?

Could post details of which Android phone you tested on please and also if you have cooked or the OEM ROM?
On the Tattoo when you rotate the phone the video view rotates too, however, I did code both the broadcast and record screens to stay in portrait mode, which could be the cause of the problem you reported.

I'll try to give you a couple of examples:
The broadcast option is intended to be used for live tracking, for example, a phone mounted in a car and broadcasting can be tracked and viewed live on the web by other people.
Here's a link to how the US Navy used the app for asset tracking.
http://www.microsoft.com/casestudies/Case_Study_Detail.aspx?casestudyid=4000005831
The record option is generally used by people for social media - here's a good example from the website

Hope that helps?
Its exactly the same on my Liquid, with 1.6

I've uploaded v1.1 which might fix this - please give it a try when you have time.
The new version is not fixed in portrait mode, so I am hoping you will get the default camera rotation - fingers crossed.
Caveat: on the Tattoo when you rotate the phone during a recording or broadcast it terminates it, so best to say either in portrait or landscape until I can resolve both issues
The GPS doesn't work on my Liquid.
I get fix and everything is ok when I go into "GPS - Enabled".
But when I start to record either in "Broadcast" or in "Record" mode, it loose fix after about 15 seconds.
And when I check the recordings it seems that the GPS data freezes at the start of the recordings, since the speed doesn't seem to change.
V1.1 seem to have fixed my GPS bug.
But the 90 degree rotation of what I see on my display is still there. As long as I keep the phone in portrait position the recording comes out correct on the web page. Will go out for another test drive now to be sure it keeps the GPS fix, and check if it updates the GPS data while I drive.
And the background is white on my Liquid now in v1.1, then its impossible for me to see which file I have marked in the Geocast folder.
Edit: nope, still the same GPS problems, can not keep fix.

Thanks for feedback above and also for your post #13.
FYI I've coded the app to drop the GPS connection after start-up to save on battery usage, so when you select broadcast or record it will re-initialize the GPS receiver, which depending on weather conditions etc, could take a while to get a fix.
In the Windows Mobile version we have an option "GPS always on", which might help (if I added that), but that doesn't help if the GPS receiver cannot fix on enough satellites (less than about 5 and you can get some random locations)
[edit] explaination about the number of satellites required for an acurate GPS location - if there are less than 3, then your location data might not change or be quite random - 4 to 7 satellites and you get resaonable accuracy ~10 satellites and then it's pretty acurate on the map.
I don't think this is the case. Every other program I use gives exact location and speed, at the same locations as your program looses fix.
Your program also takes very long time, and sometime can't regain fix at all until I turn it of and restart it. So it must be a bug.
The Liquid also have very good GPS receiver(much better than the one on the Hero), and also have A-GPS so it get fix very fast.
If the problem is that you have set the limit for how many satellites it need to approve it as good enough for your program, then at least it shouldn't affect the other GPS programs I have running at the same time.
After your program messes up my GPS, the other programs take a very long time to regain fix after I have shut down your program.
So as I said it must be a bug, and if its not then its useless since you can only use it as a video recorder, not a logger since the location you get on the map jumps all over the place, and the speed recordings show everything from N/A to 1000 kmh.

Yes, sorry it probably is a bug in the beta, but it does works fine on the Tattoo and as that is the only Android phone I have to test with I posted the link here to try and get some feedback to improve the app for other phones.
FYI there is no code in the app explicitly setting a limit on the number of satellites - my previous comment was generic about GPS, the higher the number of satellites the receiver aquires the more acturate the positioning is.
For example on the Windows Mobile version of the app it shows you on the website how many satellites the receiver has aquired throughout the tracking -- I'll need to delve into the Android APIs to see if that is possible to add to the app and that might help with debugging problems like this.
Many thanks for the feedback.
Ok, and if more guys can test it out on other devices maybe that can help too. I am subscribing to this thread and will test out a new version as soon as you have one out.
My girlfriend is using the Hero now and I don't have access to it until friday, but I will ask if she can download and test it on that.

Thanks - I think the next thing for me to concentrate on is the GPS issue, because you say the app is useless if that doesn't work correctly on all Android devices
I'll upload a new build tomorrow with some additional GPS info displayed so we can see what happens on your phone - from looking at the API I will be able to display the accuracy (in meters) that the receiver is returning - but I can't see anything in the location API that gives the satellite count.

There's an app called GPS Status that shows you how many satellites you are connected to (it shows position in a radar view and also the count). I don't know if the source code for it is available, but maybe looking at that app will be helpful to you.
GPSTest and Tricorder also show number of satellites.

[Q] Recently GPS problems

Hi all,
I have a Desire S and am very happy with it. But recently I have GPS problems.
Since I have this device I never ever had any problem with the GPS. A fix within a few seconds. The GPS of the phone had a fix faster and more stable than my Garmin I use for geocaching.
I have installed c:geo and GPS Status from the beginning. And I did not add any 'strange' programs, no games.
But since a few weeks the phone it takes a long time to get a fix. Even in an open terrain, so no trees or buildings. And when it can determine it's location it is very unstable. The phone even has trouble to determine it's location by the mobile network.
I have Android 2.3.5 and HTC sence 3.0 and softwareversion 2.10.401.8
Can anyone help me with this one? It drives me crazy....
TIA, Peter
I can only advice you to install Faster Fix from the market. It changes the GPS configuration for faster fixing. It worked for me but there are also other GPS optimization tips all over the forum, though I can't give you a specific one.
Sent from my HTC Desire S using xda premium
I had GPS problems on my DS as well, googled a bit, and found out you can change the GPS config file.
First use FasterFix, and select your location to where ever you is closest to you, then google "ntp pool" enter the website and choose a region from the right hand side. Use Root Explorer to go to your /System/etc location. Open gpsconf, and type in the "server 0.europe.pool.ntp.org" text. It will change on where you are located. Mine was Europe thats why there is ".europe.pool"
Hope i helped you out man. Peace.
Thanks guys. I will try your suggestions.
Althought I still don't understand why my phone has these GPS problems. Just out of the blue...
I had major problems with GPS fix for several days, until I made a "compass calibration" through GPS status program. A reboot might do the same, but I'm not sure.
Sent from my Desire S using XDA App
Hi all,
I did a hard reset of device and restored the factory defaults. As I did not change a lot on the device this was not a very big issue for me.
But after this the problems are gone. My device now has a fix within a few seconds.
Kind regards,
Peter

[Q] [AVD 4.1.2 - DarkMoon] - Are this issues expected?

Hello,
Can't post on developer forum since I am rookie and system doesn't allow me to post there, so I have to post it here.
I installed AVD 4.1.2 on my Zperia J (JLO) one week ago and took it for a spin for the past 7 days. However I found a few issues that do bug me and don't seem acceptable for a ROM that is so well reviewed.
I believe there is something wrong with my configuration so, please help me in case this is a mistake on my side:
1) GPS can't track... keeps looking and looking but can't fixate satelites.
2) GPS icon on notification bar, while tracking, keeping alternating with Bluetooth icon..
3) Google maps dont open if GPS is not finished with tracking.. Since I cant get it to track satelites, the only way to open google maps is to turn off GPS
4) Keyboard is missing the closing parantesis ")", so no smiles for anyone.. only frowns
5) Cannot turn off data comunication on shortcut from notification panel
6) Doesn't sinc my mail "with the native android app", despite being set in the application settings to sinc every 5 minutes
Is it me doing anything wrong or are these known issues of the ROM?
If these are known issues I'll have to roll back.. I do need the GPS very much....
Thanks

GPS not working well

Anybody seem to be having problems with their XZ Premium GPS not working as they should be? Mine is intermittent, sometimes when it works, it works well. But the moment I took a wrong turn and quickly fired up my Google Map navigator, it have problems detecting where I'm at. The Map will show the route, but my location is all over the place. It would pause and stay in that spot for a while, then move me on a lake or off road. I tried "GPS status" app to pin point where I'm at. It doesn't always want to work.
It's getting really annoying, I want it to be reliable when I need it. Lucky I still have my Z3 as backup. So far, seems like the Z3 is the best Sony ever made.
Same problem here...It is hard to start GPS....it shows current position, it lose it. I have to fight for 10 minutes until its stable.
the same issue here. OK after reboot, but problem is back again a after
I had that problem once while downtown... the buildings in that area are all old and packed pretty closely together. It just did not want to update for the life of me. Rebooting it did not seem to help it at all. Especially using the walking directions... forget it. I didn't have time to fuss with a gps app to see if I just wasn't getting any sat connections, but if it happens again I will.
Wow, so it's a known common problem. I hope it's software related so it can be fix by updates. Now I have to open two programs to make sure it always working all the time. Run "GPS Status" app and then open Google Map. Cumbersome.
Dial *#*#7378423#*#*, service test, GPS, Purge Assistance Data
This worked for me!
My use of Purge Assistance Data seemed to help, but I've had a couple of episodes of the problem since then where it didn't help. However, in the past three days the problem has not appeared. I cannot determine what has changed; many apps have updated as usual, and in order to try to determine if this is a hardware problem I ran phone in Safe mode during which problem did not appear. Interestingly (or not) the problem has not occurred during subsequently use of the phone in normal mode. BTW, I'm running the July 1st security update (45.0.A.7.90); the August 1st version has not been offered to me yet by the Software Update).

Very nice. Seem to be working very well. Although I have not put it to full use yet since I'm working at home today. Let's see how it run when I go to work in the office tomorrow.
This won't help? - - https://forum.xda-developers.com/showthread.php?p=73337848
My XZ premium is 4 weeks old and had problems with the GPS since day one. The GPS was very unreliable taking me in the wrong direction and sometimes delays in giving instructions until after passing my turns. Using google Maps and high accuracy settings. Contacted Sony today and they have asked me to contact google first to make sure there is no software issues from their side before they can look at it. Meanwhile I will download a different navigation app and see if the same problem happens.
I did GPS location test but it seems everytime I attempt it the phone seems to take forever in finding anything so I give up normally after 10 mins.
If any one has found a solution to this problem please let me know (other than changing the phone of course)
My GPS problems went away with 45.0.A.7.120
You're not alone!! I always end up going wrong directions. Compass is very way off.

+1 here. it's really frustrating as i use my GPS a lot.
I have the same issue. Second time I sent my phone to Sony. I will update the forum.
Was having this issue as well. Purned GPS Assistance data seemed to help. also did the battery trick. maybe sony should give us an update that will not allow gps to "turn off" when using apps that require it.
i searched on my phone some where on the hidden settings. The Destination was 30mins and about 20miles or so. Said the gps was only on for around 10. Cellular data was used too. This has to be a software issue. why it shuts off gps at times.

Galileo is a new GPS system developed by the EU, like GLONASS is the russian GPS and Beidou the chinese GPS.
And to answer the question, yes, our phone supports Galileo.

Yes, XZP supports Galileo. But it has not been enabled yet. :/
Had the same problem, gps not locking until I purged assistance data and rebooted the device, then it worked fine for about 48 hours until I had to repeat the process.
I completely solved this problem by uninstalling Google play services updates. This was a known issue for other phones some years ago.
Can anyone else confirm this solution?
