Smartphone shipments will grow 23.8 percent to 1.25 billion in 2014 from 1.01 billion units in 2013, said IDC.
In 2018, smartphone shipments will be 1.8 billion units, resulting in a 12.7 percent compound annual growth rate (CAGR) for the 2013 – 2018 forecast period.
In 2014, mature markets will slow to 4.9 percent growth, while emerging markets will grow at 32.4 percent.
Average selling prices (ASPs) in mature markets will be over $400, while ASPs in emerging markets will be less than $250.
Emerging market smartphone volume will grow to 920.8 million units accounting for 73.5 percent of all volume shipped in 2014. Android devices are expected to account for 88.4 percent of this volume.
Emerging market smartphone volume will be 1.4 billion units by 2018, growing to 79.5 percent of worldwide volume.
The support to Google’s Android platform from over 150 handset manufacturers has allowed it to gain the share in emerging markets.
Phablets (smartphones with 5.5″—7″ screens) will grow from 14 percent of the market in 2014 to 32.2 percent of the market in 2018.
With the expected entry of Apple into this market segment, and the pent-up demand for a larger screen iPhone, Apple has the ability to drive replacement cycles in mature markets despite the slower growth seen in recent quarters, said IDC.
