I'm not an expert in this, but I've been perusing it a bit recently.
I'm told that article is a bit out of date by randoms on twitter,
although this research was presented this week:

Also, FWIW, I can count at least five OSes in my phone (for a
definition of OS that defines a trust boundary, privileged code,
ability to install applications or backdoor, and a hunch):
1) Android
2) Baseband
3) Mobicore running in Trustzone
4) SIM Card
5) Secure Element hardware device
