LG Electronics has sold 200,000 units of its flagship V20 smartphone in the US since launching there on October 28, the company has announced.

The figure is double what the V10, the V20's predecessor, sold in the same amount of time last year, the South Korean tech giant said.

The V20 phablet was launched in South Korea late September.

Sales of the V20 and Apple's iPhone 7 surged in its home country following the ending of competitor Samsung's Galaxy Note 7.

A LG spokesman said V20's multimedia features were especially popular with young Americans who like sharing videos on social media.

The phone has the latest Android OS, Nougat, and a removable battery. It also comes with a 32-bit Hi-Fi Quad digital to analog Converter (DAC), the first for a smartphone.

Its predecessor the V10 also came with a single DAC, making it ahead of rivals in terms of audio even then.
