I prefer smartphones with kill switches, Librem 5 and Pinephone.

But you need to trust that they are actually working, and that the device was not intercepted and modified en route.

They have the schematics [0,1] for these devices and even X-rays [1] for Librem 5. Also, anti-interdiction services for the latter [2].

Isn't this rather a security theater for the more naive prospective buyers? Even if the device is verified to comply with high-level schematics, it still may not comply on the micro-level. There is the problem with all modem chips being able to access/control phone memory and being potentially controllable by the mobile network operator. How are we going to verify this vulnerability has been removed?
