Sent my Nolia Lumia 800 to Nokia at Thetford last week with a failed GPS problem. Phone delivered back today and I am thinking what a brilliant fast turnaround service until I tested out Nokia Drive 2 out after reloading everything again. SAME PROBLEM, in Nokia drive 2 phone only finds the cellular network therefore position jumps all over the place and never centres on where I actually am. Have left it out in clear sky for an hour, TWICE, still no position found. Tested again with GPSinfo same result as I put on the fault sheet A-GPS only phone does not change to accurate GPS info.
So, my question is what do I do now. Having sent it for repair and it comes back exactly the same - I have lost all faith in the system now.
