In addition to top smartphone OEMs and platforms, the comScore report also provided a list of top smartphone applications for the same period, which showed that Facebook's app led the pack reaching 76.4 percent of users. Other apps to make it to the top five included Google Play, YouTube, Google Search and Pandora Radio.

iPhone Loses To Android Worldwide

Although the iPhone dominated the U.S. smartphone market, it has a lot of catching up to do in markets worldwide where it trailed its Android-powered counterparts in the three months ending in May, according to Forbes, which cited a report from Kantar Worldpanel.

According to Kantar data, iPhone’s global market share was reportedly at 32.5 percent during the period while Android’s market share stood at 61.9 percent.

“The Samsung Galaxy S5 has had some success in attracting former iPhone owners across Europe. In general, consumers buying the Galaxy S5 were primarily attracted by its large screen size. This is something Apple is likely to address with the rumoured larger screen iPhone 6 launch expected in late September,” Dominic Sunnebo, strategic insight director at Kantar Worldpanel, said in a statement.

“Apple loyalty is high in the US, with former iPhone owners making up just 8% of Galaxy S5 sales. The majority of those switching to Samsung were LG and HTC users.”
