Apple will introduce new versions of iOS and OS X at its annual developer's conference.
Apple Makes Gains in U.S. Smartphone Market Share
Samsung was second in hardware makers with 21.4%, up from 19.5% three months earlier. HTC and Motorola both experienced significant drops in market share, while LG gained slightly.
Google's Android was the largest smartphone platform with 52.3% of smartphone platform share, down from 53.6% three months ago. Android, BlackBerry, Microsoft and Symbian all lost share, to the benefit of Apple. As a result, Apple and Google control more than 87 percent of the smartphone market.
Notably, comScore's data tracks installed user base rather than new handset sales, making it more reflective of real-world usage but slower to respond to shifting market trends than some other studies.
