Yes I know there's a series of specific Samsung models that are approved for US govt use and are likely made in a facility in south Korea.
I think we have two categories of things
A) phones made in China with software/OS load for CCP compliant censorship and data collection
B) phones made in China with software and OS load for the global market (example would be oxygenOS on an English language OnePlus phone. If it turns out there's hidden data collection or censorship frameworks in oxygenOS I would be very disappointed.)
