GPS 300km out Intermittently?

Hello

I have the Nexus 6p and have been using it fine with no hassle, 7.1.2 version of android (non root).

For some reason as of this morning my GPS has gone out of whack and puts me in two different locations Intermittently, but about 325km apart.

I have never been to this other location, and have done a full phone reset and reinstall but the problem persists unless the phone is restricted to "device only" mode for location.

Otherwise everything couple of minutes it flips between the two locations about 325km apart - the weird thing is, when it shows me in a location 325km away, it says it has an accuracy of within 10meters, how strange!

Anyway, I know the silly answer is leave it in device only GPS mode, but what wondering if anyone else had experienced anything similar? :)

(The blue dot in my image is where I actually am, the red line indicates the phantom position GPS keeps putting me when not in device only mode).
