STAMFORD, CT – Global smartphone sales to end users totaled 366.2 million units in the second quarter of 2017, a 6.7% increase year-over-year, according to Gartner.

In the smartphone operating system market, Android extended its lead with 87.7% market share, while iOS accounted for 12.1%.

"Although demand for utility smartphones remains strong, there is growing demand in emerging markets for 4G smartphones, with more storage, better processors and more advanced cameras. This is translating into higher demand for mid-priced ($150 to $200) smartphones," said Anshul Gupta, research director at Gartner.

Sales of all types of smartphones grew in the second quarter compared with the same period last year. However, rising component costs are a concern, as is limited supply, due to the reduced availability of critical components.

"We expect a shortage of flash memory and OLED displays will affect premium smartphone supply in the second half of 2017," said Gupta. "We've already seen Huawei's P10 suffer from a flash memory shortage, and smaller, traditional brands, such as HTC, LG and Sony, are stuck between aggressive Chinese brands and the dominating market shares of Samsung and Apple in the premium smartphone segment."
Samsung's smartphone sales grew 7.5% year-over-year after three consecutive quarterly declines. The company had been hit hard by problems with the Galaxy Note 7, but the Galaxy S8 and S8+ are bringing back high demand for Samsung smartphones.

"Despite growing competition from Chinese brands such as Huawei, Oppo and Vivo, we expect Samsung to register growth in 2017," said Gupta.

Despite clearing the distribution channel of iPhone inventory amounting to 3.3 million units during the second quarter, Apple's sales were down 0.2% year-over-year.

"Apple's sales in emerging markets are expected to grow as older generation iPhones continue to attract buyers. The new iOS 11, which will include augmented reality, machine learning, an improved Siri and a new display design, will likely fuel strong iPhone sales in the fourth quarter of 2017 and help Apple increase its sales in 2017."

Vivo and Oppo achieved the best performances in the second quarter, with year-over-year sales increases of 70.8% and 44.1%, respectively. Vivo's smartphones with front-facing cameras have carved out a niche for themselves.

"Vivo maintained second place in China and grew its sales internationally," said Gupta. Similarly, Oppo secured its leading position in China by offering dual rear-facing and front-facing cameras.”

Greater China and emerging Asia/Pacific markets drove sales of smartphones, with market shares of 27.7% and 21.4%, respectively.

Growing smartphone penetration of India, Indonesia and Southeast Asian countries drove a year-over-year rise in smartphone sales in the emerging Asia/Pacific group. However, smartphone sales in Greater China declined year-over-year, primarily due to longer replacement cycles, and as users prefer to buy better smartphones.

"Large vendors continued to strengthen their positions by increasing their market share, while smaller brands lost ground in Greater China."

Sales in Western Europe returned to year-over-year growth, fueled especially by strong sales of Huawei and Samsung smartphones.
