How do we know there isn't a bug in a device's airplane mode?

  How do we know there isn't a bug in a device's off switch? Most of them are software-based these days.

    Most of them allow you to take the battery out if it comes to that.

      Like all the iPhones, iPads, and unibody MacBook Pros?

      But nobody actually does, so clearly we're content to trust the software on that matter.

        They do if the power button malfunctions. Are you aware of any devices that cannot be turned off because of a software error?
        • mikeash 15y ago
          How could you even tell if you had one?

          nknight mentioned iphones, ipads, and unibody macbooks.

    The off switch is almost certainly much more thoroughly tested, and most of its failure modes are much easier to detect.
