Yeah, keep believing that. In IFixIt’s iPhone 12 Pro Max tear down, the only Samsung parts are the 6GB RAM (among Micron, SK, and Toshiba suppliers) and likely the OLED display and its driver chip. LG supplies the 6.1 OLED for the iPhone 12 and in those iPhones probably the driver chips.
So sure, there’s at most 3 Samsung parts and at worst ZERO Samsung parts in the latest iPhone 12 series phones. But most of Apple iPhone parts, No, that would now be Texas Instruments, Qualcomm, and of course, Apple own A-series CPU’s, U1, and power controller chips.
