Tablet computer sales fell in the second quarter of 2015, with market leaders Apple and Samsung losing ground to other vendors, a survey showed.
The survey by IDC said tablet sales fell in the April-June period, marking a third consecutive quarter of declining year-on-year sales. Total tablet sales were 44.7 million units, down 7 percent from a year earlier, and 3.9 percent from the prior quarter.
Apple remained the top vendor with 10.9 million iPads sold in the past quarter, for a market share of 24.5 percent. But iPad sales were down 17.7 percent from a year earlier, and Apple lost more than 3 points of market share.
Samsung was No. 2 with 7.6 million tablets sold, for a 17 percent market share. The South Korean giant saw unit sales down 12 percent from a year earlier. But the market saw modest growth from Lenovo, the No. 3 vendor, and explosive growth from China's Huawei and South Korea's LG, tied for fourth.
IDC said the tablet market is cooling after explosive growth following the introduction of the iPad in 2010.
"Longer life cycles, increased competition from other categories such as larger smartphones, combined with the fact that end users can install the latest operating systems on their older tablets has stifled the initial enthusiasm for these devices in the consumer market," said IDC analyst Jitesh Ubrani.
"But with newer form factors (for PCs) and added productivity-enabling features ... should be able to bring new vitality to a market that has lost its momentum."
Lenovo sold 2.5 million tablets for a 5.7 percent market share, with unit sales growing 6.8 percent.
Huawei doubled its sales from a year ago to 1.6 million units. LG also sold 1.6 million units, a 246 percent increase from the previous year, IDC said.
