An electronic device with a display and a touch-sensitive surface receives notification(s) while the device is in a screen-off state. After receiving the notification(s), the device detects an input for waking the device to a screen-on state. In response, the device transitions to the screen-on state and displays the notification(s) on a wake screen user interface. The device further detects another input for dismissing the wake screen user interface and ceases to display the wake screen user interface. Afterwards, the device detects a third input for redisplaying the wake screen user interface. In response, upon determining that the third input meets notification-clearance criteria, the device redisplays the wake screen user interface without displaying at least one of the notification(s); and upon determining that the third input does not meet the notification-clearance criteria: the device redisplays the wake screen user interface and redisplays at least one of notification(s).
