Just get a new phone and sync a back-up…unless it just might be beneficial PR to, apparently, do the “risky” thing and carp about it.
So far, I see ZERO corroborating evidence—even something as simple as a suitably redacted screenshot of an email to Google support.
Trust, but verify & extraordinary claims require extraordinary evidence.
