A method comprising: at an electronic device with a touch-sensitive display and a plurality of applications, including a camera application : while the device is in a locked, passcode-protected state: displaying a lock screen interface (5000-E) on the touch-sensitive display, the lock screen interface including a camera access indicia ; detecting a first gesture on the touch-sensitive display; in response to a determination that the first gesture starts on the camera access indicia and is of a first type : displaying, on the touch-sensitive display, an indication of a second type of gesture required to access a restricted session for the camera application; in response to a determination that the first gesture starts on the camera access indicia and is of the second type: ceasing to display the lock screen interface; starting the restricted session for the camera application; displaying the interface for the camera application , without displaying a passcode entry interface; and maintaining the device in the locked, passcode-protected state for at least one application in the device other than the camera application; and in response to a determination that the first gesture starts at a location on the touch-sensitive display other than the camera access indicia: forgoing displaying the indication of the second type of gesture required to access the restricted session for the camera application. while the device is in a locked, passcode-protected state: displaying a lock screen interface (5000-E) on the touch-sensitive display, the lock screen interface including a camera access indicia ; detecting a first gesture on the touch-sensitive display; displaying a lock screen interface (5000-E) on the touch-sensitive display, the lock screen interface including a camera access indicia ; detecting a first gesture on the touch-sensitive display; in response to a determination that the first gesture starts on the camera access indicia and is of a first type : displaying, on the touch-sensitive display, an indication of a second type of gesture required to access a restricted session for the camera application; in response to a determination that the first gesture starts on the camera access indicia and is of the second type: ceasing to display the lock screen interface; starting the restricted session for the camera application; displaying the interface for the camera application , without displaying a passcode entry interface; and maintaining the device in the locked, passcode-protected state for at least one application in the device other than the camera application; and ceasing to display the lock screen interface; starting the restricted session for the camera application; displaying the interface for the camera application , without displaying a passcode entry interface; and maintaining the device in the locked, passcode-protected state for at least one application in the device other than the camera application; and in response to a determination that the first gesture starts at a location on the touch-sensitive display other than the camera access indicia: forgoing displaying the indication of the second type of gesture required to access the restricted session for the camera application. <EOS>
