A slowdown in smartphone sales in China is cooling the global market for the devices, research firm IDC said Tuesday.
The market tracker said global smartphone sales will see a rise of 11.3% in 2015, following robust growth in 2014 of 27.6%.
IDC said the overall market is still moving forward thanks to growth in other countries and estimated sales rising to 1.9 billion units by 2019 from a projected 1.44 billion this year.
"Smartphone volume still has a lot of opportunity in the years to come, but two fundamental segments driving recent years' growth are starting to slow," said analyst Ryan Reith.
"As reported earlier in May, smartphone shipments in China actually declined year over year in the first quarter of 2015, showing that the largest market in the world has reached a level of maturity where rapid growth will be harder to achieve."
Reith said China has been a key driver of Android, accounting for 36% of total volume in 2014.
Growth for Android, the free operating system from Google, will be only around 8.5% this year due to the China slowdown, according to IDC.
The forecast showed Android is likely to remain dominant this year with 79.4% of the market, while Apple's iOS boosts its share to 16.4%.
Windows Phone, the struggling mobile system from Microsoft, is likely to grab a 3.2% market share as unit sales increase to some 46.8 million, IDC said.
