> iPhone may do something special to detect that Apple seem to have lockscreen "keyboard mash detection" for macOS (where, if you are cleaning your keyboard and therefore mashing down keys as you swipe across them with a cloth, the OS will wake up and process the random inputs a while — until it detects that you've mashed 4+ function-row keys at once, at which point it'll just go back to sleep) so I wouldn't put it past them to have similar logic for iOS.
