But here's what really hurts Google. According to Net Applications, 61.2% of mobile Web users use the Safari Web browser that comes as a default on all iOS devices. This is up from 54.9% in January. Android has only a 18.6% share, followed by Opera Mini with 14% (which Facebook has reportedly been looking at as an acquisition target). So, even though Android is supposed to have a market share advantage over iOS, Apple users out-browse Google Android users by a 3.3x margin. It gets worse. A ComScore study in April found that 70% of American Android users can't seem to figure out how to use WiFi on their devices. They found that 29% of iPhone users only connected to the Internet using nothing but cellular data. In the UK, only 13% of iPhone users solely used wireless data to get on to the Web. But in the U.S., 68% of Android users relied on their wireless carrier to do their internet browsing.
