Samsung Electronics' Galaxy S4 has been selling faster than any of its predecessors in the top-selling smartphone line-up.
"As of the end of April, we supplied four million Galaxy S4 handsets to telecommunication operators around the world," an executive at the company said on Friday.
Samsung officially unveiled its latest handset on April 26 and had supplied 4 million units worldwide within five days. In contrast, it took 85 days for the company to shift 3 million of its S1 handsets, 55 days to do the same for the S2, and 21 days for the S3.
"As of Friday, we have sold more than 6 million units, and we predict that we could break the 10-million mark by as early as the end of this month," the company said.
