- strcat 1y agoThat standard Android toggle doesn't turn off USB support at the OS level but rather controls the default USB gadget mode. USB gadget functionality is one part of the high level USB functionality. That doesn't block USB peripherals, USB-C alternate modes, etc. and leaves nearly all the kernel attack surface being exploited by Cellebrite intact.
