Gartner said more than 156 million Android smartphones were sold in the first three months of the year, or 74.4 percent of the global total. That compared with 56.9 percent in the same period a year ago.
South Korean electronics giant Samsung, the largest maker of Android phones, boosted its lead in the marketplace with a 30.8 percent share, up from 27.6 percent a year earlier.
Apple held second place with its iPhone and iOS operating system, accounting for 18.2 percent of smartphones and the same percentage for its operating system, the Gartner survey showed.
"There are two clear leaders in the OS (mobile operating system) market and Android's dominance in the OS market is unshakable," said Gartner's Anshul Gupta.
The survey showed the BlackBerry operating system in a distant third place with a three percent market share, just ahead of Microsoft Windows at 2.9 percent.
Among manufacturers, South Korea's LG was third largest with a market share of 4.8 percent, followed by and Chinese makers Huawei (4.4 percent) and ZTE (3.8 percent).
