Re: iPhones and Androids
"using Apple's A12 system-on-chip" I think I see the problem here.
Is this similar to Intel's Management Engine?
Not at all.
Apple manufactures their own ARM CPUs and name them A12, A13 or whatever. They're not that different from Qualcomm Snapdragon, Samsung Exynos or many other mobile CPUs.
If you're referring to "system-on-a-chip" ('SoC'), it just means that the CPU has more stuff integrated than just the CPU logic, and all the other mobile ARM CPU's are SoC's as well.
