The Fastest Smartphone on the Market: What Makes the S4 Tick?

By Your Mobile Life on at

It's time to grab a slice of birthday cake and warm up those vocal cords as RAM has turned the ripe old age of 62! And my, what a way it's come since it's early incarnation on 11 May 1951.

Without RAM, many of our day-to-day devices simply wouldn't function – from PCs and laptops to smartphones, tablets and games consoles.

We've got a lot to thank it for, not least the power of the Samsung GALAXY S4, so we hope you'll join us in giving it the birthday celebration it deserves as it prepares to start drawing out of what we can only assume is a huge pension pot.

What is RAM?

RAM, or Random Access Memory to give it its full title, allows devices to access chunks of memory without having to file through the chronological storage method which hard drives use to hold data.

This means RAM can offer up information at much faster speeds, although its capacity is much lower than your main storage device and all data is removed when the device is switched off - with all your data saved on the main storage.

Adding more RAM to a computer (or similar device) will allow it to process more information at once, therefore increasing the amount you can use and radically improving performance.

Where it all Began

The date is 11 May 1951, the location is the Massachusetts Institute of Technology and Professor Jay Forrester and a team of researchers have just produced something dubbed Project Whirlwind.

This project came about after the US Military decided it required faster computing power so it could run real-time flight simulations, and though Project Whirlwind never made it into any of those simulators, the foundations for RAM as we know it today had been laid.

Technically Random Access Memory had been around before 1951 – with cathode ray tubes being used to store electrically charged bits of data - though Whirlwind was where RAM became reliable, practical and speedy.

Where we are Now

Fast forward 60-odd years and you'll find RAM rapidly accelerating, with the technology getter smarter, faster and smaller, thus giving devices such as the Samsung GALAXY S4 and the rest of the GALAXY range the capability to deliver blisteringly fast speeds before your very eyes.

There was a time not too long ago when 2GB of RAM in a PC was seen as cutting-edge, but we're now seeing that sort of power in smartphones, along with quad-core processors making their way into devices which fit into the palm of our hand.

RAM and the GALAXY S4

Samsung has always been at the leading edge of technology and RAM is no exception, with the GALAXY S4 sporting 2GB of the latest LPDDR3 RAM, allowing you to use the handset in ways that were never possible before.

The benefit of having a large chunk of RAM on your GALAXY S4 is simple. It means you can have more apps open in the background, reducing the endless opening and closing cycle, and allowing you to get on with your life without being forced to wait for your phone to load.

As well as the cutting-edge RAM, the GALAXY S4 also packs a powerful processor punch with the choice of a supercharged 1.9GHz quad-core chip and superfast 4G network connectivity or a market leading octa-core option which harnesses the power of eight cores.

This perfect combination of processor and RAM means the Samsung GALAXY S4 is ready to take on any task, and process it in a blisteringly fast time.

RAM and Android Jelly Bean

The Samsung GALAXY S4 comes running the latest version of Google's mobile platform - Android 4.2.2 Jelly Bean.

Jelly Bean has been specifically developed with speed and simplicity in mind thanks to Project Butter, and coupled with Samsung's intuitive TouchWiz user interface and the power under the hood the GALAXY S4 provides you with one of the best smartphone experiences going.

You'll always find the GALAXY S4 offers a smooth and fluid smartphone experience, allowing you to glide between homescreens, effortlessly scroll through emails and continuously jump between apps without having to break a sweat, or waste any time.

Seamless Multi-tasking on the S4

We're always multi-tasking on our phones and, whereas this task can become more of a chore on handsets that don't feature industry-leading RAM and processing power, with the GALAXY S4 it's a breeze.

The 2GB of LPDDR3 RAM inside the S4 allows you to have more applications running at any one time than ever before, making the device the perfect tool for both business and pleasure.

With Multi Window, you can also have two apps displayed on its Full HD Super AMOLED 5-inch screen at once, so if you don't want to stop watching the latest blockbuster while you respond to an important email, say, or check something out online, you can simply make your movie share the screen with another app and you won't notice any slowdown or interruption in video playback.

Sensing the World with the S4

All that high-end power in the Samsung GALAXY S4 comes in handy when you're interacting with one or more of its nine sensors, which allow you to control your smartphone in new and exciting ways.

With Smart Scroll you can gaze at the bottom of the screen and the page you are viewing will begin to scroll without you having to lift a finger. And with Air Gesture, simply swipe your hand above the S4 to make the gallery scroll to the next image. Finally, with Smart Pause, if something interrupts you watching a movie, you needn't miss a thing as the GALAXY S4 will recognise that you're not looking at the screen and instantly pause your film.

Fast, intuitive and inventive controls like these are not possible on other handsets, as they do not have the technology or sheer processing grunt behind them to make these futuristic ideas a reality, today.

Downloads at the Speed of Life

There's nothing people love more than downloading the latest app, game, tune, movie or TV show on their smartphone and with the GALAXY S4 it just got even better.

Thanks to the 2GB of RAM, punchy processor and connectivity options such as 4G and Wi-Fi b/g/n, you can download content to the S4 in almost no time at all, giving you more time to actually enjoy your content.

It's easy to find the media you want on the GALAXY S4 as well, with the well-stocked Google Play store accompanied by the Samsung Hub - which reveals the best content available so you're not left endlessly scrolling through stuff you don't want.

Plus, don't forget you can even control your TV using the GALAXY S4 thanks to its inbuilt infrared blaster and excellent WatchON application.

Supercharged World Wide Web

It's not just the awesome gestures, next-gen eye-tracking and speedy downloads that set the GALAXY S4 apart from the crowd. Oh no, it also delivers a top-notch internet experience.

The full HD display and powerful components inside the S4 give it the best foundations for browsing the web, and it makes mincemeat of even the most complex desktop sites.

Web browsing on phones has previously struggled to match the responsiveness and ease of use you get with a computer, but the GALAXY S4 changes that giving you an excellent way to surf the internet without the need for a full-size computer.
