Emergency call mode is a convenient way to implement incoming calls, but at least when an unauthorized user picks up the phone they have the ability to *attempt* to unlock it. On an incoming call, there is no way at all to even attempt an unlock.
We should at least allow the user to try, and if they get the passcode correct, they should be able to use the device in full. Would probably also be a good idea to at least show the indicators, even if they don't respond to input until after unlock. It's important to be able to see what time it is and how much battery is left, regardless of whether the user is authorized.
