The Massachusetts Department of Public Health is facing a class action lawsuit that says they "coluded with Google to repeatedly auto-install contact-tracing spyware on the Android smartphones of over a million Massachusetts residents, without their permission or consent". Google is not a defendent but I'd expect they clarify what they did to get the app onto Android phones without owner knowledge at some point.
From the suit that may affect you...
At least two dozen other States have developed contact-tracing apps using
Google API. These other States engaged in community outreach and encouraged their residents
to voluntarily download the apps and opt-in for contact tracing. Massachusetts, however, is the
only State to surreptitiously embed the Contact Tracing App on mobile devices that DPH locates
within its borders, without obtaining the owners’ knowledge or consent.
If you passed through(or over) Massachusetts with an Android phone you may have the secret app installed. HOW it was done will likely become a key focus of the suit.
