Android owns more than 70 percent of the smartphone operating system market in the South American countries of Brazil and Argentina, according to a new report from global analytics firm Kantar Worldpanel.

Android was by the far the most popular mobile operating system in the two South American countries featured in the report. In Argentina, Android holds a comfortable 71.8 percent market share and an even more impressive 87.6 percent in Brazil. The statistics reflect a three-month period ending March 2014.

Both countries showed a preference for the Windows Phone operating system as second choice. In Argentina, Windows garnered 12.9 percent and in Brazil, 5.5 percent.

The report shows that BlackBerry is the third most popular operating system in Argentina with 9.9 percent. Apple's iOS, which is incredibly popular in the United States, meanwhile only has 1.7 percent of the Argentine market. Around 3 percent of Brazilians choose Apple's iOS and 1.5 percent prefer BlackBerry.

Interestingly enough, Android's dominant numbers actually represent a slight decline from a previous report focusing on a three-month period ending February 2014. During that time, Android controlled 72.7 percent of the smartphone operating system market in Argentina and 87.9 percent in Brazil.

The report highlights a trend that has shaped the mobile industry since last year: Android is no longer playing second fiddle. Various reports focusing on the 2013 mobile market indicate that Android ran away with around 80 percent of the smartphone market last year. Although iOS remains popular in the United States (38.7 percent popular, according to the Kantar report) Android has the edge in many countries around the world outside the West. An earlier Kantar report showed that Android phones accounted for 84 percent of smartphones sold in Latin America in December 2013.

"We expect Android's growth to slow further in 2014 due to market saturation, and rivals like Microsoft or Firefox will be ready to pounce on any signs of a major slowdown for Android this year," reads a Strategy Analytics report from the beginning of 2014.

Last year also marked the first time that Android tablets were able to outsell their Apple counterparts.

"As the Android tablet market becomes highly commoditized, in 2014, it will be critical for vendors to focus on device experience and meaningful technology and ecosystem value -- beyond just hardware and cost -- to ensure brand loyalty and improved margins," wrote Gartner research director Roberta Cozza earlier this year.
