Typically, the app needs to ask for permissions like that, though. On Android, they need to ask to become a "Device admin", and they need to specify what specifically they'll use that access for. I imagine (though I'm unsure since it's never happened to me) they need to ask to update those permissions if they want their uses to change.

Agreed, but its not perfect. I recall but couldn't recover a link to a story about some application bypassing android or iPhone permissions.

Another big recent flaw allowed apps without the permission to draw over other apps.
