An electronic device, while in a restricted interaction mode in an application other than a call application, displays a first user interface that includes a plurality of user interface objects, and receives an incoming call. The electronic device determines whether the incoming phone call satisfies predefined signaling criteria. In accordance with a determination that the incoming call satisfies the predefined signaling criteria, the electronic device outputs a signal that indicates the incoming call. In accordance with a determination that the incoming phone call does not satisfy the predefined criteria, the electronic device foregoes outputting the signal indicating the incoming call.
