Samsung today announced that it has sold 40 million Galaxy S4 around the globe, achieving a great milestone especially when the device has been through a strong competition in recent months since launch. Samsung’s CEO JK Shin made this statement while talking to the Korean media.

The number is only relevant to the original Galaxy S4 units distributed on the market since the launch, and doesn’t include the other variants such as S4 Active, S4 Mini and S4 Zoom. Shin also stated that 40 million units are sold in exact five months after the launch makes us conscious of the success that has been able to get the device, although Samsung were expecting a little more.

The Galaxy S4 has been achieving record sales since its debut across 60 countries. Samsung sold 30 million units in first four months followed by another 10 million units in last 30 days. Compared to the year-ago-quarter, Samsung sold 30 million Galaxy S3 last year, hence the successor device has been a true success and undoubtedly doing better.

Possibly, Samsung might have expected results even better, but certainly it’s a remarkable result especially when they are getting direct competition with Apple. The Galaxy S3 has had challenges and faced stiff competition from other high-end handsets, while the Galaxy S4 has struggled in recent months with devices such as the HTC One, the Sony Xperia Z and of course, the iPhone 5.

As expected, Samsung has also started rolling out Android 4.3 for Galaxy S4 – particularly international GT-I9505 model now — to keep the momentum up. Android 4.3 Jelly Bean update for Galaxy S4 includes few key improvements and features such as support for Open GL 3.0, Galaxy Gear compatibility, improved memory management and tweaked TouchWiz launcher. In addition to new features, new Samsung keyboard and browser, and Reading mode have introduced.
