Smartphone Usage

As indicated by the graph, the majority of users who used smartphones for their Twitter activity did so through an Android smartphone. A smaller percentage used an Apple iPhone and only very few used a Blackberry phone. Although ISIS announced in mid-December 2014 that members of its organization are no longer allowed to use iPhone products for security reasons, the ISIS Twitter Census found only a 1% decrease in the use of the iPhones in early February 2015.
