S5-metal-version-release-rumouredThe Samsung Galaxy S5 has finally arrived and was unveiled this week at a packed Samsung event at the 2014 Mobile World Congress. A lot of the speculation and rumours which we've reported on over the last few weeks and months turned out to be pretty accurate. The S5 is absolutely bursting with great features and specs so here's what you need to know.

Similar in size and styling to the Galaxy S4, the Galaxy S5 also sports a plastic design this time with a metal surround and has measurements of 142 mm height x 72.5 width x 8.1 depth. It weighs in at slightly more than the S4 at 145grams and sports a textured raised pattern on the rear for a better grip. The S5 also has the added bonus of being robust and as well as water and dust resistant, features which proved popular with the Galaxy S4 Active. We're going to have to wait a little bit longer for a Samsung smartphone with a 2k screen however the Galaxy S5 none the less impresses with its Super AMOLED 5.1-inch, 1920 x 1080 display which gives it a very decent resolution of 432 pixels per inch.

The speculation was correct concerning a fingerprint scanner. Like it's big rival Apple, Samsung have installed a fingerprint sensor just underneath the home button. However Samsung's fingerprint sensor, which requires a swipe of the finger to activate, can also be used to authorise online Paypal payments as well as unlocking the S5 handset. You can register 3 different fingerprints with the Galaxy S5 and is the handset also includes a 'Private Mode' where files and photos can be stored in a secure area of the smartphone and can only be accessed by using the fingerprint reader.

The Galaxy S5 also has a some fantastic fitness features - located just below the camera on the rear of the phone is a heart rate sensor. The heart rate sensor tracks your pulse and works in conjunction with the new S Health 3 software to monitor your health and fitness. The upgraded S Health 3 also keeps tabs on calories you burn and has a pedometer function to record the number of steps taken.

The S5's main rear camera is 16-megapixels in size and comes with a very speedy (0.3 seconds to be precise) autofocus which makes it the fastest camera on a smartphone. It comes with some of the latest camera technology including 4K Ultra High Definition video and a HDR preview mode when you're using it in to take photos. It also has a Shot and More mode which can help you choose the best settings for your pictures and a slow motion function. In addition, there's a 2-megapixel camera on the front.

As we'd expect from Samsung, the S5 also has some great specs under its cover. It runs on the latest Android KitKat 4.4.2 operating system and is powered by a 2.5GHz quad-core Snapdragon 800 processor. It comes with 2GB of RAM and there are options of 16 or 32GB of internal storage and a microSD slot which increases it up to 64GB with a microSD card. It also boasts superb download speeds thanks to a download booster which combines the WiFi and LTE connection to maximise the bandwidth for fast downloading large files.

The 2800mAh battery will provide up to 21 hours of talktime and a good couple of weeks on standby. The Galaxy S5 has a handy Ultra Power Saver Mode which can eke some power out of the battery and gives you a countdown on how much battery time you have left.

The Samsung Galaxy S5 will be available from April in a choice of 4 colours including Charcoal Black, Shimmer White, Electric Blue and Copper Gold.
