Samsung has reportedly shipped 6 million Samsung Galaxy S4 smartphones and is on track to top 10 million by month's end.
According to South Korean newspaper Chosun Ilbo, which cited an unnamed company executive, Galaxy S4 shipments surpassed 4 million by the end of April and were at 6 million one week ago.
At that rate, the exec thought the new phablet could top 10 million shipments by the end of May.
A Samsung spokeswoman said she could not confirm the numbers provided to Chosun Ilbo. But recent Galaxy smartphone releases have seen impressive numbers.
In January, Samsung announced that total sales of its flagship Galaxy S smartphone, which debuted in 2010, had topped 100 million units.
The original Galaxy S smartphone, launched in June 2010, had sold some 24 million units as of January, with 10 million purchased during the first seven months of launch, Samsung said. The follow-up Galaxy S II, launched in April 2011, reached the 10 million sales mark in five months, and had logged sales of around 40 million units earlier this year.
The Galaxy S4's predecessor, the Samsung Galaxy S3, achieved 20 million global sales in 100 days, and also passed the 40 million unit sales mark as the beginning of the year.
Samsung unveiled the S4 in March. The 5in Galaxy S4 includes 2GB of RAM and a 1.9-GHz quad-core processor. The GS4's 1,920x1,080 screen runs on an enhanced version of Google's Android 4.2.2 Jelly Bean. It comes in 16GB and 32GB, with expandable memory up to 64GB.
At this week's I/O developer conference, Google unveiled a version of the Galaxy S4 running stock Android, which will be available next month.
