A larger number of American teens are getting their hands on smartphones and in turn are increasingly heading online via their mobile devices rather than using desktop or laptop computers. The findings come from the most recent Teens and Technology survey from Pew Research Center.

One in four teens ages 12 to 17 consider themselves “cell-mostly” internet users. A full 78% of teens own a cell phone, and 47% of them own smartphones. That translates into 37% of all teens who own smartphones, a rise from 23% in 2011.

In terms of other connected devices, 23% of teens have a tablet computer, and 93% of the youth demo have a computer or have access to one at home.

The report, which is based on a survey of 802 parents and their 802 teens, is the second in a series of reports issued in collaboration with the Berkman Center for Internet & Society at Harvard. The first release, Teens, Parents and Online Privacy, was published in November 2012
