Worldwide mobile phone sales to end users totaled nearly 426 million units in the first quarter of 2013, a slight increase of 0.7% from the same period in 2012, according to Gartner. Worldwide smartphone sales totaled 210 million units in the first quarter of 2013, up 42.9% from the first quarter of 2012. The Asia Pacific region was the only region to show growth in mobile phone sales for the quarter, with a 6.4% increase on year.

　　"More than 226 million mobile phones were sold to end users in Asia Pacific in the first quarter of 2013, which helped the region increase its share of global mobile phones to 53.1%," said Anshul Gupta, principal research analyst at Gartner. "In addition, China saw its mobile phone sales increase 7.5% in the first quarter of 2013, and its sales represented 25.7% of global mobile phone sales, up nearly 2pp on year.

　　"China-based and local manufacturers have been exemplary at addressing demands of buyers by offering affordable devices with optimum features such as 2.5G (EDGE) instead of 3G in a smartphone. In the smartphone market, local and China-based manufacturers are making faster inroads as they account for 29% in the first quarter of 2013, up from 13.2% a year ago."

　　In the first quarter of 2013, sales of mobile phones in the EMEA region declined 3.6%. The North America and Latin America's mobile phone market fell 9.5% and 3.8%, respectively, while Japan saw its mobile phone sales drop 7.3%.

　　Samsung remained in the No. 1 position, growing 13% in the first quarter of 2013. Its share of smartphones reached 30.8%, up 3.2pp from the first quarter of 2012. "We expect the new Galaxy S4 to be very popular despite being more of an evolution than a truly revolutionary device compared to the S3," said Gupta.

　　Nokia's mobile phone share dropped 4.9pp in the first quarter of 2013 mainly due to a steep decline in feature phone sales. Although Nokia's Windows Phone sales have sequentially improved reaching a volume of 5.1 million units, Nokia is yet to see high growth in the smartphone segment. Nokia's position in the smartphone market dropped to No. 10 in the first quarter of 2013, from No. 8 in the fourth quarter of 2012.

　　Apple's sales to end users reached 38.3 million units in the first quarter of 2013 as Apple was able to burn some of the inventory built at the end of 2012, as iPhone 5 was rolling out in more markets, and as the company prepared for Lunar New Year. China is a key contributor to overall sales for Apple, and Gartner analysts saw evidence of this in the first quarter of 2013, when sales reached close to seven million units in China alone thanks to the lower price of the iPhone 4. "Apple is faced with the challenge of being increasingly dependent on the replacement market as its addressable market is capped. The next two quarters will also be challenging, as there are no new products are expected to be coming before the third quarter of 2013," said Gupta.

　　LG electronics moved in front of ZTE in the first quarter of 2013 for the No. 4 position. ZTE had a weak performance, failing to grow its smartphone sales, selling 7.9 million smartphones in the first quarter of 2013, a 5.1% decline from the fourth quarter of 2012.

　　In the first quarter of 2013, smartphones accounted for 49.3% of sales of mobile phones worldwide. This is up from 34.8% in the first quarter of 2012, and 44% in the fourth quarter of 2012. On the other hand, sales of feature phones contracted 21.8% in the first quarter of 2013.
