I remember there was some guy who installed spyware on a phone that couldn’t be wiped off by normal means. Stuff that gave him remote camera access, location, file access, everything. Then he got that phone stolen and made a documentary about this dude’s life.
I think it was baked into the OS somehow (probably what you said). He disabled system updates as well so the OS didn’t wipe. The only way it could have been removed was flashing the OS, but you’d have to find out it was there to begin with.

I remember that, he installed it as a system app and would persist through a factory reset
