A method is performed at a mobile device with a display. The method includes displaying a first mode of a plurality of modes of the device. The first mode of the device is active when a first set of time and/or device location criteria are met and the second mode of the device is active when a second set of time and/or device location criteria are met. While the first set of time and/or device location criteria are met and the first mode of the device is active, the mobile device detects a first input that overrides the first mode of the device. In response to detecting the first input, the mobile device activates the second mode of the device. The mobile device detects a second input and, in response to detecting the second input, performs an operation in the second mode of the device.
