Android is now the top-selling smartphone platform in Southeast Asia, with volumes growing more than 1,000% in the course of a year, according to market research.
GfK Asia estimates that Android accounted for around 40% of handsets sold during the quarter ending in September.
The operating system has climbed two positions in the last two quarters, overtaking BlackBerry OS and Symbian.
These three platforms power a combined 90% of all smartphones sold in the region - which GfK estimates to be more than 4.7 million units during the quarter.
Smartphone shipment volumes grew 9% from the prior quarter, while the total value of units sold grew 6% over the same period to nearly $1.5 billion.
GfK notes that there is variation between the most popular platforms in individual markets, with RIM still in the lead in the major market of Indonesia, while Symbian is on top in Vietnam.
