Mobile device context aware determinations

Abstract

Systems and methods are provided for mobile device context aware determinations. In one implementation inputs are received in relation to a location which corresponding to an incidence of deceleration, the inputs are processed to determine a likelihood that the deceleration is to be maintained for a shorter and/or longer time duration, and based on a determination that the deceleration is to be maintained for longer, a restriction at a device can be modified. According to another aspect, first time intervals which correspond to navigation instances associated with a first instruction provider and second time intervals which correspond to other navigation instances can be received, the first time intervals can be compared with the second time intervals to determine an efficiency of the first navigation provider, and based on a determination that the first navigation provider is relatively efficient, a recommendation to select the first navigation instruction provider can be provided.
