Lumia 900 GPS bug

So I've had the Lumia for about a week now and for the most part I like it. But lately I've been running into a bit of a brick wall with any sort of Map application I use.

 

Now I use maps on my phone a lot, especially when traveling, so this is a huge deal to me. Whenever I hit the button to show my current location, instead of pointing to Denver it either points me to Roswell, GA or Akron, Ohio. Never having been to either state this is incredibly bizarre, and I can't think of any reason my phone would do this. I downloaded other map utilities to test it out, so I can confirm it's not app related.

 

At first I thought it might have just been some weirdness related to the office building where I work, but when I got home I was getting the same thing. I've already had to get the phone replaced once because the capacitive buttons on my first model died, so I'm hoping I don't have to do that again.

Re: Lumia 900 GPS bug

Hi ClockworkNinja,

 

Thank you for your post and welcome to the forums!

 

We're sorry to hear about your problem. This has been mentioned on the forums before, and is very odd indeed. Please check this link for the previous discussion.

 

I have escalated this issue to our technical experts who will look into this. As mentioned in the other thread, the problem may be caused by your SIM card or your operator, so we would advise you to contact them on this matter as well.  

 

Let us know how you get on,

Re: Lumia 900 GPS bug

Just go and exchange your defective phone for another one. It's got nothing to do with SIM card or operator.

Re: Lumia 900 GPS bug

Pulgchild,

 

If by 'the other thread' you meant that one I posted on May 10th,

/t5/Maps-Navigation-and-GPS/Lumia-900-GPS-fails-when-battery-is-50-or-below/td-p/1396825

 

then no, the SIM card trick doesn't fix it. I like to know what you might discover from the internal investigation.

 

Asking the user to exchange for a new phone would be a convenient answer, I don't want to go through that process yet. Hypothetically, if its something wrong with the hardware, wouldn't it more likely to show random gps locations rather than the exact same two places?

Re: Lumia 900 GPS bug

The map location probably defaults to specific places instead of random locations if the GPS doesn't work. You could wait for a software fix but it is highly unlikely as other users are not having the same problem. The most probable reason is a hardware defect which can only be resolved by exchanging.

Re: Lumia 900 GPS bug

i am seeing the same problem, although it seems unrelated to how full the battery is. i am in Washington DC currently and the phone keeps saying i'm in Akron, OH. i have not been to Akron at any point. i've tried restarting the phone, at which point launching the maps app briefly shows DC, but then zooms over to Akron again.

 

i'm currently installing the latest phone update, and i'm going to try resetting the phone after that if it still doesn't work. i don't want to have to reinstall all my apps, though. that sucks.

seems like a lot of other users are having this same problem, from a quick googling.

Re: Lumia 900 GPS bug

What seems to have worked for me in this case is the following:

1. Be connected to Wi-Fi

2. Turn off the AT&T data under settings

3. Launch Maps and tap the current location button

4. Maps should adjust this to be the right location

 

Then to verify if it is working... 

5. Turn on AT&T data

6. Turn off Wi-Fi

7. Launch Nokia Maps... 

8. Go to current location -> should reflect the right location.

 

And then you can turn on Wi-Fi again.  This seemed to do the trick just fine for me.  Hope this helps!

Re: Lumia 900 GPS bug

Same here.

 

Turning on and off "Aiplane" mode seems to help - but it is a temporary fix. After a day or so my Lumia thinks I am in Akron, OH.

Re: Lumia 900 GPS bug

I'm in Chicago and taking some nice pictures, tweeting, trying to find and check in to local places.. and the phone keeps thinking I'm in Akron. There is absolutely nothing I can do to revert it back to Chicago. It's extremely annoying, specially with geotagging photos in COMPLETELY INACCURACY! Come up to the issue and own it Nokia.

Re: Lumia 900 GPS bug

Same issue here, GPS still saying I'm in Akron , OH, if I reboot the phone and turn off Cellular Data and Turn ON Wi Fi connected to my house, then it gets the right location, but once I turn on Cellular Data again, after 5 or so minutes it goes back to Akron.,  I really think is a software issue, if I go outside to the street I do get the right loctaion, but if I go outside and the gps have to calculate my location based on triangulation then it goes back to Akron.

Re: Lumia 900 GPS bug

Same problem here.  Just happened this morning for the 1st time in well over 4 weeks of use.  My wife & I have two WP7 Nokia Lumia 900 purchased a week apart.  The issue affected both phones at the same time simultaneously.  The problem affected all Apps that use GPS positioning (System View did show wrong GPS position @ Akron Ohio).  I tried a bunch of things including some mentioned above to no avail.  After reboot, I would open the map and it would 1st display my actual location (correctly) for a split second and then move immediately to Akron Ohio.  So, Ï went into the settings of the Maps Apps (...) and tapped the "clear map"menu. And ... Now everything works!  Maps works, Nokia Maps works, Realtor.com works, even the System View displays the correct GPS location.  But wait, what if I reboot?  Let see:  Go To Maps ... & ... Yes, correct location!  This trick worked on both phones (time will tell for how long).

For System View I am using System View Pro Version 1.2 by Rainbow Dreamworks & System Information Version 1.0 by Eyjo.

 

FYI.  To help troubleshoot the problem :

Phones Versions are:

    Nokia Lumia 900 - alias - Nokia Lumia 900 RM-823

    Hardware:    112.1914.2.0

    firmware:      2175.1003.8112.12085

    OS:               7.10.8112

    .net clr:         3.7.11140.0

    time zone:    UTC-05

Re: Lumia 900 GPS bug

So is this problem still resolved for you? Ever since the other day, my a-gps (assisted gps) does not work. It just defaults to Akron, OH. I find it interesting that this problem happened to a lot of people on the same day. Something tells me it has something to do with AT&T's network. How else could we all have this problem on the same day? It is not a GPS issue because the GPS (Satellite) works fine. If I go outside and wait a minute or so, it knows exactly where I am. But if I am in my house, it thinks i'm in Akron. Indoors, A-GPS is used as you can't get satellite reception indoors. Even when this was working the day before yesterday, it never really worked that well. It would show me where I was on the map, which looked accurate, but when I tried using an app (Nokia Transit), it seemed to have wanted a true GPS signal, not assisted GPS. This is acually my 5th(!!) Lumia 900. Yep - they all had some kind of a bug. At this point, I wish I could return the phone. The problem is, the only better phone is the iPhone..which i don't really want to go back to. Anyway, if anyone (Nokia??? hello??) knows of a fix for this, I'd much appreciate it. I'm really hoping this is not a hardware issue.

Re: Lumia 900 GPS bug

Well, @ 17:12 EST I am back to Ohio.

@ 17:25 all of a sudden I am back to my location ...

@ 17:58 -> back to Akron Ohio

I have no idea why that is ...  I don't think it's HW and I don't think it is based on activity because 2 phones bought 1 week apart have the same issue at the same time - confirmed.  A hardware problem would have revealed itself much sooner.  It does seem that both phones fail to locate the GPS coordinates and go to some sort of default location that may be in Ohio for the Eastern US.  The AT&T angle is interesting, but why would the AT&T network somehow interact with the GPS satellites?  Technically, you would have to go the extra mile and write quite a bit of code to "force"a device to somehow "need" a "network" in order to use GPS and/or GLONASS.  Any way, I seriously doubt that AT&T is behind this since GPS and GLONASS do not belong to AT&T at all (independent). 

In System View Pro, I have GPS location, and it does show the wrong GPS coordinates in Ohio.  Military Compass does the same thing.  So, I think that it is a GPS/GLONASS based issue.  GPS is based on triangulation and time.  Keyword is TIME (as in exact time to the ns).  The device must be Time synchronized perfectly in order to determine GPS coordinates.  Could there be an issue there?

Any how, this is a CRITICAL problem since so many apps depend on your location in order to function properly.

NOKIA must look at this issue and  I hope that they monitor this exchange.  This could reveal something deeper that may affect a greater number of people later on and become news (as in "something bad happened").

Re: Lumia 900 GPS bug

Update: I just reverted the update that came out about a week or so ago but the problem did not go away. Then, I re-applied the update and everything seems to be okay now. Well, it thinks about 2 blocks from my house now which is much better than Akron. So far so good. I will keep this thread updated if anything changes.

Re: Lumia 900 GPS bug

Oh, I forgot to mention that I was outdoors (country side).  So I didn't think it was A-GPS.  A-GPS should triangulate from the towers to assist standard GPS signals (if poor - in cities usually), so depending where you are, it may or may not work (or be of no use).  If it turns out to be A-GPS, then it would be most interesting to know why you need A-GPS in the middle of nowhere when other devices (try Garmin) clearly can catch the GPS satellites without a glitch (and great accuracy) at the exact same location.  Also, it did not work when I had my 3G/4G turned off. 

 

It's about 23:30 Zulu time, so I doubt we'll hear from Nokia until tomorrow (provided they read this).

Meanwhile, here is something to read: http://en.wikipedia.org/wiki/Assisted_GPS

My lumia started doing this today. I've NEVER had this issue. Even after a restart it won't work. Takes WiFi to fix. :/

Re: Lumia 900 GPS bug

My phone did this today for the first time as well.  So far I have only been able to display my correct location for about 30 seconds.  Extremely frustrating, but I am learning alot about Akron.

Re: Lumia 900 GPS bug

I am still having the problem.  Meanwhile, a friend of mine got the Nokia Lumia 900 about 4 weeks ago.  She has not run the latest updates from Nokia yet and, she does not have the problem at all.  So the question is, for the folks who are experiencing this issue, did you run the last Nokia Updates about a week ago (if I recall correctly)?
