According to the research firm, over 281.6 million units of smartphones were shipped worldwide in the first quarter of 2014.
"This growth was led by strong smartphone sales in emerging markets (excluding China); the fastest growing regions were emerging Asia/Pacific, Eastern Europe, and the Middle-East and North Africa," Gartner said in a statement.
Due to these high-performing regions, the emerging markets achieved a 40 per cent increase in sales during the quarter.
Samsung led the market with 21.3 per cent share, followed by Apple (13.1 per cent), Microsoft (7.2 per cent), LG Electronics (4.3 per cent) and Lenovo (4.2 per cent).

During the said quarter, local brands and Chinese vendors came out as the key winners (in smartphones) in emerging markets, Gartner Research Director Anshul Gupta said.
"These vendors recorded an average growth of 73 per cent in smartphone sales and saw their combined share go up from 38 per cent to 47 per cent during the first quarter of 2015," Gupta added.
"We expect Samsung's drop rate to be slower than that seen in recent quarters with sales of its new S6 smartphones starting in the second quarter of 2015, and its Galaxy Alpha receiving good response," he said.
Apple continued to exhibit a strong performance in the quarter, particularly in China. IPhone sales were up 72.5 per cent (60.17 million units) during the first quarter of 2015.
Lenovo, Huawei and LG Electronics followed in the smartphone tally with 5.6 per cent, 5.4 per cent and 4.6 per cent share, respectively in the reported quarter.
