Sure. Networking is the obvious one, then comes similar stuff like Bluetooth, then you've got stuff like peripherals; headphones, hardware keyboards, and to a lesser extent stuff like USB storage. You have state changes like charging and not charging. To a lesser extent stuff like switching SIMs or removing SD cards. More broadly, i.e., stuff that isn't networking or peripherals, you have stuff like the screen being on or not, wheyher the screen is locked or not, whether the phone has been unlocked since a restart (and therefore the filesystem still partially encrypted), you have power saving modes, dynamic brightness changes. While a lot of these also apply to more traditional computing, I'd say on a phone that many of them are more prone to changing rapidly, part of a more integrated device (for instance, turning off your phone screen is usually a very different kind of action that merely turning off your monitor), and generally effect the function of the device to a greater extent. Would you agree?
