Android is at the top of the charts for smartphone sales in the U.S., Australia and five major European markets, a first for the OS. Results from a recent survey show Android's share rising to 84.1 percent in Spain, and it has at least half of the smartphone sales in Great Britain, Germany, France and Italy.

According to the survey conducted by Kantar Worldpanel ComTech, the sales were recorded over 12 weeks, ending on June 10. Though Android is the leading OS in the U.S., that has dropped 6.8 percent from last year. Many respondents who wanted to spend less than U.S.$80 on a smartphone chose Android-powered devices, which attributes to its market growth.

"It's great time for Android. It was only less than four years ago when Google launched its first mobile OS. Ten versions later, Android holds more than half of the global smartphone market share, it completely dominates the low-end smartphone market, and it also established itself on the high-end market with phones like Samsung Galaxy SIII and HTC One X.

It's not going to continue like that forever, though. On the low-end, two open-source mobile operating systems will try to steal some Android's lion's share. The first version of Tizen was already launched a few months ago, and Mozilla intends to release Firefox OS in the next several months. On the high-end, Apple will release the highly anticipated new iPhone 5 very soon, and surely all of the attention will turn to them."
