(nothing I am about to say is necessarily personal; I am genuinely grateful for the link!) Is there a table of these requirements as columns and vendors as rows? I think most of this list is acquired by having a modern CPU or SoC, no? Much of the list is software requirements. There is one item that sticks out: Support for disabling USB data and also USB as a whole at a hardware level in the USB controller Just how much of the hardware list is satisfied by say having a Snapdragon SoC? I would prefer if people said such and such vendor is missing such and such feature which we need. Always NAME the SPECIFICS. A link to a web page with the exact specifics missing for the most popular phones would help, imo. This is clear and educational. Instead we get “they don’t got no good hardware maaaan.” It’s annoying. Looks handwavy even when it is not.
