Samsung may face its first ever year-over-year decline in smartphone shipments this year, a new market report from TrendForce has indicated.

According to the new forecast, Samsung’s year-over-year smartphone shipment totals are expected to drop one percent in 2015 thanks in part to a reduced number of predicted Galaxy S6 shipments. The report also attributes the predicted dip to losses in low-end and mid-range markets due to increased competition from Chinese companies, like Huawei. For the full year 2015, Samsung is expected to ship 323.5 million units total.

Contrarily, number two smartphone maker Apple is expected to achieve a year-over-year growth of 16 percent with about 223.7 million units shipped in 2015.

Despite the anticipated overall slip, Samsung remained a strong competitor in the third quarter, accounting for around 25 percent of all global shipments. Huawei also made notable gains in the third quarter, becoming the first Chinese smartphone-maker to pass the 100 million unit mark for smartphone shipments in a given year. The company is expected to see a whopping 40 percent growth over its 2014 figures. Xiaomi, which also hoped to hit the 100 million shipment mark for the year, is expected to fall short of its target but is still forecast to achieve 14.6 percent growth in annual shipment totals.

Approximately 332 million units were shipped in 3Q 2015, TrendForce reported, hitting a third quarter growth figure of 9.1 percent over the prior quarter this year. TrendForce’s latest projection shows that the global smartphone shipments are set grow by 9.3 percent overall in 2015 before slowing to an annual growth rate of 7.7 percent in 2016.

“Emerging markets such as Southeast Asia and India are now the major battlegrounds for vendors as developed markets have become fairly saturated,” TrendForce wrote of the impending slowdown. “Increasing competition also means profits will fall in spite of steady shipments, and this will be the primary issue that most vendors will have to deal with in the near future.”
