The Galaxy S5, which was unveiled at the Mobile World Congress in Barcelona, Spain, will be available in 150 countries, including India, on April 11. However, the company did not announce the price of the new smartphone.

It sports a slightly larger 5.1-inch Super AMOLED (1080 X 1920p) display which looks similar to that of the Galaxy S4.

Powered by a 2.5GHz quad-core processor and 2GB RAM, the Galaxy S5 will come in 16GB and 32GB internal storage variants, which will be expandable up to 64GB through microSD card.

While acknowledging the market murmur about lesser-than-expected sales of Galaxy S4, Shin revealed that Samsung had so far sold over 200 million units of Galaxy S series phones. Galaxy S4 was launched in the summer of 2013. It has faced tough competition from the likes of Apple iPhone 5 and 5S, LG G2, HTC One and Sony Xperia Z1.

Usually, Samsung launches flagship Galaxy phone every year after World Mobile Congress (MWC). But, this year, the company announced Galaxy S5 at the MWC because it wants to replace Galaxy S4 as soon as possible.

In Galaxy S5, Samsung has introduced several unique features aimed at fitness conscious users in a bid to steal Apple's thunder. It is widely rumoured that the iPhone maker will launch the successor of iPhone 5S with a clutch of health and fitness-related features.

"With the enhanced S Health 3.0, the Galaxy S5 offers more tools to help people stay fit and well. It provides a comprehensive personal fitness tracker to help users monitor and manage their behaviour, along with additional tools, including a pedometer, diet and exercise records, and a new, built-in heart rate monitor," said a Samsung spokesperson.

"Galaxy S5 users can further customize their experience with an enriched third party app ecosystem and the ability to pair with next-generation Gear products for real-time fitness coaching,"

Another highlight of the phone is a new iPhone-like fingerprint sensor integrated with the phone's home button. The finger scanner will offer a biometric screen-locking feature and mobile payment experience to consumers.

The Galaxy S5 sports a 16MP rear camera and a 2.1MP front-facing camera. The rear camera is capable of capturing 4K video at 30 frames per second. Samsung claimed the Galaxy S5 offers the world's fastest auto-focus speed up to 0.3 seconds.

The smartphone runs on Android 4.4.2 KitKat, the latest version of Google's mobile operating system. It is IP67 certified dust and water-resistant. The back panel of the phone sports a dimpled soft-touch cover, similar to the Nexus 7(2012) tablet.

In terms of connectivity options, the Galaxy S5 offers Wi-Fi 802.11 a/b/g/n and ac, Bluetooth 4.0, USB 3.0, NFC and InfraRed. The phone supports a large number of 4G LTE frequency bands with LTE Category 4 standard. It comes with accelerometer, gyro, proximity, compass, barometer, RGB ambient light, Gesture (IR), and heart rate sensors.

The phone packs in 2800mAh battery with a claimed standby time of 390 hours and talk time of 21 hours. It will be available in four different colours: charcoal black, shimmery white, electric blue and copper gold.

Along with Galaxy S5, the company also announced the Gear Fit, a new fitness band. David Park, a senior Samsung executive, said, "Gear Fit is for people who want the functionality of Gear 2 smartwatch, but in the size of a fitness band."
