I would expect any electronics mass produced in China has PLA mandated backdoors in addition to anything the CIA adds.
That’s probably the back doors being piggybacked.
“...China has PLA mandated backdoors in addition to anything the CIA adds.”
The tech at the iPhone Store says...
“I’m sorry sir, but we won’t be able to repair your iPhone. Apparently, there’s an internal conflict between the CIA-installed spyware and the Chinese-installed spyware. Frankly sir, that kind of repair is beyond our expertise. Have you considered calling the CIA? I understand they have a pretty sophisticated technical branch.”
Apple controls everything about the iPhone and there are no backdoors. Some Android phones have such backdoors in them, not all.
