This IDC study analyzes the installed base of smartphone users in the United States by operating system (OS). It combines IDC's extensive knowledge of smartphones, smartphone users, subscribers, subscriber growth, and challenges and opportunities for different operating systems. Findings in this document are based on information gathered from primary and secondary sources during the past six months.
"Smartphones continue to grow among consumers amid feature phone decline, although the way consumers are purchasing and holding on to devices is changing," says Brian Haven, senior research analyst with IDC's Consumer Mobility team. "A strong secondary market as well as the fact that the device has been decoupled from the service component have led to consumers turning to non–service providers for device purchase, as well a growing trend of outright device purchase at the full retail price."
