Majority of mobile users now use smartphones, blame those young people.

Nielsen's mobile report for Q3 2013 shows that more and more teens have convinced their parents to get them smartphones, especially during back-to-school season. Usage of non-dumb devices among those in the 13 to 17 year-old range has reached 70 percent, a nice 12 point growth over September last year. A prodigious 79 percent of all users aged 18 to 24 are also toting smartphones, contributing to the 64.7 percent total of all US mobile owners who have now traded their feature phones for something more advanced. Android continues to leadthe battle of the operating systems with 52 percent, though it's held that share since mid-2012. While Apple's iOS trails close behind with 41 percent, it actually tops the list of smartphone makers in terms of OS share. Despite Cupertino's continued reign in the hardware department, Samsung's market slice by OS has increased by 2 percent, while Nokia and HTC saw a slight bump, thanks to their new Windows Phone models. Meanwhile, BlackBerry held steady at 3 percent despite its billion dollar lossin the second quarter. If you digest numbers better with a side of images, check Nielsen's charts after the break.
