You have location turned on on your phone?
Any sort of google enabled tracking?
I would look there...Google knows where you been.
I think its not nefarious by the Dr. I think its a Google thing...I would be interested in others ideas.
ROBO callers are rampant on the internet today. I get several
a day but I don’t answer. I let it go to answer mode and they
never leave a message and I block them to my phone there after.
