Samsung Galaxy S4: Everything you need to know

The rumour roller-coaster ride is almost over. The invites are in and now, finally, we know when we will first set eyes on the next Galaxy, the Samsung Galaxy S4.

On 14 March 2013, Samsung will unveil its flagship Android phone which could, in theory, set the standard for all smartphones for the year to come. If everything goes to plan, that is. But what do we already know and what has been rumoured? Read on to whet your appetite for what is to come from Samsung.

Samsung Galaxy S4 release date

Samsung Mobile's Twitter account gave tech fans the world over sweaty brows when it announced "Ready 4 The Show" and "Come and meet the next Galaxy".

Alongside the tweet was a press invite to a New York-based Samsung Unpacked event, with a reveal penned for 7pm ET (midnight UK time) on Thursday 14 March. Given the history of these Unpacked events, Samsung will have the Galaxy S4 on show for us to take a look at.

What we can't be sure of is just when the SGS 4 will land in stores and in the hands of customers. The Galaxy S3 was unveiled in London's Earls Court on 3 May and put on sale just a few weeks later on 30 May.

Samsung could do much the same thing here, especially given HTC has already played its trump card this year with the new HTC One handset. Incidentally, HTC's phone was announced on 19 February and will hit stores and networks on 15 March, so this month will be very exciting for smartphone fans.

We'll find out the official Samsung Galaxy S4 release date at the event itself, we fully expect.

Samsung Galaxy S4 screen

Rumours point to the SGS 4 being fairly big on the display front with a 5-inch Full HD Super AMOLED screen being its flagship feature. Pocket-lint's own trusted source confirms this to be true.

With a screen that big, things are moving closer to Note territory. A leaked roadmap also backs up this claim, with an apparent 441ppi screen shipping with the Galaxy S4.

More recent rumblings have suggested that Samsung is struggling with the manufacture of the display units at this size and may opt for LCD instead, but from what we've heard, this is highly unlikely.

Samsung Galaxy S4 processor

Processor rumours for the SGS4 are especially exciting. A 1.8GHz Exynos 5 8-core processor has cropped-up and been widely suggested.

Benchmarks of a GT-I9500 have appeared online, showing a phone with a seriously high score in the AnTuTu benchmark test. While they don't verify rumours of an 8-core handset, they do show a 1.8GHz processor.

Again, our own source also backs up claims of an 8-core processor. However, it will actually be more a 4+4-core processor, with the extra cores being utilised for power management rather than extra wellie - much like Nvidia's fifth core in its 4+1-core array.

More screenshots, this time in leaked hands-on pictures of a device a Chinese forum poster claims to be the SGS4, also show that the processor is 1.8GHz.

Samsung Galaxy S4 camera

HTC has kicked up a big fuss over how great the camera is in its new HTC One phone. Expect Samsung to be doing just the same. It seems that the 13-megapixel sensor is the norm for flagship devices, but will Samsung change tack like HTC?

Unfortunately, it seems, no. Our source says that the camera on the rear will be 13-megapixel. As do the leaked hands-on pics from China. The front-facing camera, we have been told, will be 2-megapixel.

Interestingly, it may come done to the software itself to give Samsung the edge. Samsung Orb appears to be an attempt at tweaking Google's Android 4.2 Photosphere imaging tech for Samsung's own phones, although it might be produced by Samsung in-house.

Whatever the camera turns out to be, expect both front and back to be HD capable, with 1080p video recording on the rear and 720p (at least) on the front.

Samsung Galaxy S4 design

A few pictures claiming to be of the Samsung Galaxy S4 have appeared online over the last couple of months, with this one still being one of the most convincing. The leak came from sammobile.com and shows what looks like a snap from a computer screen showing a picture of the phone.

The problem is that it could very easily be faked and its similarities in looks with the SGS3 also have us wondering if it is simply an enlarged version of that, with the home key removed, which we're not sure Samsung would do.

The other convincing pictures, that at least show a phone if not the Samsung Galaxy S4 itself, are those of the aforementioned hands-on by a Chinese forumite.

There's much to suggest that the person who posted the pictures is barking up the wrong tree, but we have one niggling doubt. The bezel and rear of the alleged SGS4 in the shots has the same dotted pattern design as the background in Samsung's marketing materials, both in the teaser video it has released and on the posters currently looming over Times Square in New York.

Samsung Galaxy S4 eye-tracking tech

The New York Times is convinced that the Samsung Galaxy S4 will feature new eye-tracking technology. There will be several applications of this, it says, including Eye Scroll, where the phone will automatically scroll down on a web page, for example, if you look at the bottom of the screen.

The Samsung Galaxy S3 did feature a form of eye recognition, where it would stay on without going into screen standby mode if you were still looking at the screen, but this new tech will be much more advanced. Certainly, knowing Samsung, there will be several cunning software gimmicks pulled out of the bag on the night.
