Question [Q] GPS keeps turning itself on

Not sure why this is happening. Never had this problem in first three months I've had this phone and now suddenly for the last 5 days, the GPS just won't stay turned off. If I switch it off from location services it just switches itself on again 3 minutes later. Have tried disabling Google Maps and other apps that use location, tried factory reset, still the same thing.

I found a few threads talking about this problem:

They all say it's something called CarrierIQ. Does anyone know if Sony Xperia C also has this crappy horrible spyware, and if so, is that to blame? What else could be causing this?

Thanks!
