Some theoretical bug. It happens, even in simple stuff.

More likely would be e.g. a platform finally getting a halfway decent way to store secrets (which iOS got with the 3GS and even better with iOS 5/6/7), and which Android as a whole still lacks (specific manufacturers are adding it, like Samsung, but it's not a standard due to Google being insane). I don't see a zombie client rapidly adopting those new storage technologies.
