@martin.fd , That's how the GPS self test works. Go to the last item (summary) in the self test menu to see what is tested and the result.
Please go to settings>applications>see all apps>google maps>3 dots>uninstall updatesthen restart phone.Does that help?
I wrote on Nokia chat with this problem. They told me, that the compass problem can cause some apps. Make sure to restart device in Safe mode and slowly delete apps that use location services. If it does not help, try hard reset the phone. Hmm. The user needs a stable and reliable mobile device and does NOT spend half a day repairing problems. When I had an iPhone, these things always worked 100%. I wanted to give the chance to Android and Nokia but this is a disappointment.
