Norton Security Anti Theft "Locate" is not working correctly

Anti-Theft option "Locate" does not find the phone.  Tried turning off the WiFi and also the Norton WiFi Security.  "LOCATION" on my android was turned off.  Turned it ON and then tried again. It took a long time, but it seems to have finally found the phone.  Does LOCATION have to be turned on my cell all the time for Norton's Anti-Theft to work? 

 

Yes. Location services has to be turned on for the Locate functions to work. How else could the location be detected by the device and then sent back to Norton.
