Abstract: Various arrangements for handling a call by a mobile device and/or selecting a function for execution by the mobile device are presented. A phone call may be commenced by a mobile device. During the phone call, the mobile device may collect proximity data that indicates the mobile device is not proximate to an ear of a user. The microphone of the mobile device may be muted in response to the proximity data that indicates the mobile device is not proximate to the ear of the user.

Abstract: This disclosure describes techniques for automatically detecting transitions in captured video and using the detected transitions to mark portions of the captured video for editing, where editing may be deleting, retaining, or playing at a faster playback rate the marked portions. During video capture, a video capture device may obtain image information and determine based on image and sensor information the presence of a transition from a target scene to a non-target scene. The image information may be obtained from a video front end sensor (e.g., image sensor) and the sensor information may be obtained from other sensors that provide orientation information (e.g., accelerometer, compass, and the like). A processor may determine automatically or based on user input how to edit the marked portions.
