Abstract: Systems and methods for functionality management of devices are disclosed. Multiple computing devices may be located in the same environment and/or space and at least two of those computing devices may be configured to perform a given functionality. In these and other examples, one of the devices may be identified as a primary device and the other devices may be identified as secondary devices based on, for example, historical usage data, audio-signal data, computer-vision analysis, and/or one or more other criteria. The functionality may be disabled on the secondary devices until the secondary devices are utilized and/or until a triggering event occurs.
