That's down from 17.57 trillion Korean won ($ 15.1 billion) for the same period a year ago. Sales fell 5% to 62 trillion won ($ 53 billion) from the same period last year but improved 10% from the previous quarter.
"Third quarter profit fell sharply from a year earlier but improved from the previous quarter, as stronger smartphone sales and improved utilization in mobile OLED screens were weighed down by continued weakness in the memory chip market," the company said in a statement .
The company said smartphone sales "improved significantly" this quarter due to strong sales and robust shipments from Samsung's latest flagship phone, the Galaxy Note 10, along with its Galaxy A series.
Samsung has benefited from the current troubles facing Huawei, the world's largest telecommunications equipment maker and no. 2 smartphone seller.
Research firm Canalys said in August that Samsung rocketed to a 40% market share in Europe, its highest in five years.
"Samsung has been quick to capitalize on Huawei's [US] problems, working behind the scenes to position itself as stable alternatives in conversations with important retailers and operators," Canalys analyst Ben Stanton said at the time.
The US ban also puts a dent in Huawei's ambitions to dominate the global 5G smartphone market.
As the market gears up for the next generation of ultra-fast wireless technology, Daishin analysts predict Samsung will have the upper hand "as virtually the only 5G smartphone manufacturer in the world outside China."
Samsung said it expects consumer demand for 5G devices to rise in 2020 as 5G networks expand globally.
"The company plans to offer more 5G devices and foldable products to enhance its competitiveness and build a foundation for further growth," it said.
