Control-F "baseband"

Funny you should mention that. I just watched Brian Lunduke's latest show talking about the Librem 5, which will include a hardware switch for the separate baseband chip which will be physically isolated from the rest of the system. Not here yet but it's good to see the awareness building: https://www.youtube.com/watch?v=4SwE9W8JasA

I don't understand what you want to say.

Baseband processor is the magical chip that lives on its own, even if you "switch off" your phone and you are not allowed to tamper with it by most developed countries legislation (i.e. you can only take what is offered to you, sanctioned by government but will be punished if you make any modifications to it). See Neo 900 developers talking about it. So separating it off should allow better sleep to all paranoid users that might think they are being monitored.

And what did you hope to read about the baseband processor's relationship to the OS?

You're replying to someone other than me.

However any mobile OS advertising itself as 'private and secure' is just lying if it is installed on a handset that hasn't dealt with the baseband issue - and none of them have or likely will.

Are we talking about binary blobs for the baseband processor?

Baseband processor on most phones can access RAM/storage/IO at will even if the phone is "turned off".
