I've heard people unironically say that Asian people can only be creative in the West because of freedom or some shit. At least that's a step up from the outright racists who claim only white people are capable of creativity.
i suspect that this lack of detail is characteristic of the sanctions. my head hasn't been in the semiconductor game for decades, but any laymen like me could see that the sanctions had obvious loopholes that enabled china to proceed and i wonder if that's intentional or because the politicians lacked this kind of detailed knowledge.
Not sure about their newer phones but I had a P8 that was built like an absolute tank. Took it to -40C and back repeatedly during a trip up North and it was still usable 2 years later. Gave it to my grandma when her Samsung crapped out. I’m pretty sure it’s still in working condition.
I am sure it will keep working with your grandmother. They are built exceptionally well. It's the lack of continued os and security updates that concerns me. If they could match samsung and googles 5 years of updates they would be the only phone I use
