Os,ui,features: one of the iphones with lidar.

Functions: it depends on what you see yourself doing. I keep an android phone for the second number and using as a usb drive, sd card reader, other computer crap. It’s rare that i use it though, the circumstances where i want to host pxe boot or something and don’t have a computer are few and far between.

Ai: I don’t know. Most of it is done in the cloud so the phone doesn’t actually matter.
