Samsung has reportedly sold more than 40 million units of its Galaxy S4 range of smartphones in the past six months.
Samsung CEO JK Shin revealed that it took just a month for the South Korean company to sell the first 10 million units of the device, which was launched on April 27 this year.
According to Mashable, it took the smartphone manufacturer about two years to sell the same number of units of its Galaxy Note devices.
By comparison, tech giant Apple has sold 31 million iPhones in the third quarter of 2013, the report added.
