In the fourth quarter of 2009, the market registered a single-digit growth as mobile phone sales to end users surpassed 340 million units, an 8.3 per cent increase from the fourth quarter of 2008.
Three of the top five mobile phone vendors experienced a decline in sales in 2009 (Nokia, Motorola and Sony Ericsson). The top five vendors continued to lose market share to Apple and other vendors, with their combined share dropping from 79.7 in 2008 to 75.3 per cent in 2009.
On the OS side, the two best performers in 2009 were Android and Apple. Android increased its market share by 3.5 percentage points in 2009, while Apple's share grew by 6.2 percentage points from 2008, which helped it move to the No. 3 position and displace Microsoft Windows Mobile.
