Samsung's Galaxy S4 has reportedly hit the 40 million unit sales mark, suggesting that there's still plenty of love for the 5-inch smartphone.

A Samsung exec said the quad-core beauty has now tipped over the big 4-0, according to a report in Korean-language site inews24 (via Google Translate). I've contacted Samsung for confirmation, and I'll let you know if I hear anything back.

The Galaxy S4 went on sale in April, with sales reckoned to have hit 10 million just under four weeks later. Just over two months after that, in early July, the 20 million milestone was hit, suggesting that sales may have slowed ever so slightly during the summer, or at least leveled out.

All these numbers should be taken with a pinch of salt, as it's hard to know precisely when particular milestones were met, and Samsung's numbers generally represent sales to retailers, rather than sales to actual individuals. That said, it appears that the Galaxy S4 may be selling at roughly the same pace as last year's S3.
