A first version of a notification associated with an application is displayed. A first input is detected on the first version of the notification. If the first input meets application-launching criteria which require that the first input has ended without having met a first input threshold, launching of the application is initiated in response to the first input. If the first input meets notification expansion criteria which require that the first input meets the first input threshold before an end of the first input is detected, an expanded version of the notification is displayed in response to the first input. A second input is detected on the expanded version of the notification. If the second input is outside of the expanded version of the notification, the expanded version of the notification is dismissed; and if the second input is on the expanded version of the notification, application launching is initiated.
