According to research firm Kantar WorldPanel, Android operating system is the fastest growing OS in the market. In Europe, smart phones running Android are more popular than Apple's products to iOS. During the twelve weeks of the year, which ended in April, the operating system from Google in some European countries more than doubled its presence. This happened in Spain, Germany and Italy, where the market share of Android OS has reached 72%, 62% and 49% respectively. The position of Apple's iOS remained strong in the U.S. and the UK, which ensured her place in the second quarter, but the markets of continental Europe's position weakened under the pressure of new devices with Android. In the same UK there is a high demand for smartphone HTC One X, which is the first Android-smartphone with quad-core processor. The demand on the Island was so great that up to 12 weeks in 2012, of which only one One X was present in the market, he was in the top 10 most sold vehicles. Some increased interest in and to the operating system, Windows Phone, which was due to the massive impact of sales of Nokia. Although sales of the company Nokia is not growing, but the connection among the Finnish manufacturer selling WP7-smartphones, leads to increase in the proportion of such devices. In Germany, this OS has doubled its presence reached 6%, while in the U.S., Britain, France and Italy, its share has reached a level of 3-4%. The greatest regression predictably reached the Symbian and BlackBerry. However, if it is officially Symbian leaves the market, the decline in the share BlackBerry from 9% to 3% - a very significant event.
