Comment 4 for bug 1573674

Location is working again for me. What I did, which I think is what got it working again:

1) Go to location settings and disable both WIFI and GPS location (alone this did not work)
2) Go to energy saving preferences and disable WIFI and GPS (this is what probably fixed it)
3) Turn back on WIFI and GPS
4) Turn back on WIFI and GPS location - location icon stopped flashing
5) Use a mapping service that requested my current location - this still did not work.
6) Press and hold down power button and select reboot
7) Phablet did not reboot but hung with dull back light so held down power button for a long time until it turned off. (This is probably a separate problem. )
8) Hold down power button to boot

Wohey, location based service now works!

I don't think I have a GPS connection as I am indoors, but at least WIFI location is working correctly now.
