Abstract: Call control information regarding a phone call that a user of a mobile communications device is currently engaged in with an individual is displayed on a screen. A request to display in-call contact information is received, and in response to the request the in-call contact information regarding the individual is displayed. This request can be a single user input, and the in-call contact information can include information obtained by the mobile communications device from a social networking service.

Abstract: Techniques are described to implement a user interface for a display of a mobile device. In an implementation, the user interface may include a chromeless menu configured to be displayed when menu-based user input to the mobile device is available; a system tray configured to be displayed on the display when a notice containing status information affecting operability of the mobile device is available; and a task switcher module operable to cause a chromeless overlay be displayed over an active application being executed by the mobile device to allow selection of one or more applications of the mobile device.

Abstract: Notification techniques are described. In an implementation, an unlock screen is displayed by a mobile communications device that indicates that one or more keys of the mobile communications device are locked. If an input is detected at the mobile communications device to remove the lock, an animation is displayed that gives an appearance that the unlock screen is a page that is being turned and removing the lock of the one or more keys.

Abstract: Unlock screen and notification techniques are described. In an implementation, an unlock screen is displayed by a mobile communications device that indicates that one or more keys of the mobile communications device are locked. If an input is detected at the mobile communications device to remove the lock, an animation is displayed that gives an appearance that the unlock screen is a page that is being turned and removing the lock of the one or more keys.

Abstract: A mobile communications device user interface is described. In an implementation, a method is implemented by a computing device that includes displaying content in conjunction with a first level of a hierarchical menu in a user interface on a display device of the computing device. Responsive to receipt of an input to navigate to a second level of the hierarchical menu that is a sublevel of the first level, the second level in displayed conjunction with the content on the display device, the content having a reduced display richness when displayed in conjunction with the second level than when displayed in conjunction with the first level.

Abstract: A mobile communications device home screen is described. In one or more implementations, a method is performed by a mobile communications device that includes receiving status updates of contacts from a social network service. A home screen of the mobile communications device is configured to include the status updates.

Abstract: Column organization of content is described. In an implementation, a mobile communications device configures a user interface to include a plurality of representations of content arranged according to a plurality of columns that permits navigation between first and second said columns upon detection of a gesture input via a touchscreen of the mobile communications device. The user interface is displayed on a display device of the mobile communications device. The first column is configured for vertical navigation through each of the plurality of representations and the second column includes a filtered subset of the plurality of representations such that at least one of the representations is included in the first column and not the second column.

Abstract: Location-based display characteristics in a user interface are described. In an implementation, a determination is made by mobile communications device that icon is to be displayed at a particular location in the user interface. A display characteristic is applied by the mobile communications device that is defined for the particular location such that a display of the icon is changed. The icon is displayed having an applied display characteristic on the display device of the mobile communications device at the particular location in the user interface.
