On the back of the handset is a 13-megapixel camera, which is a step up from the 8-megapixel found on the Galaxy S2 and S3 models. On the front will be a 2-megapixel camera. It will have 4G LTE connectivity, Wi-Fi, NFC and a IR Blaster. The 2,600mAh battery has been improved and in which the handset should be able to last throughout the day.

With Samsung's latest device the Galaxy S4 being rumoured to be released later today, this will be the final round of the most anticipated rumours that will either be confirmed or denied by Samsung at their Global Unpacked Event at around 11pm tonight.

The S4 is rumoured to be coming to users with eye-scrolling, allowing you to change and scroll pages using only a movement of the eyes. Bloomberg however has stated that “sources familiar with the devices” have said the S4 will not have anything even like this. With the best scenario being simple eye tracking (to pause videos when you look away) and the worst, being that this technology will be on future Galaxy S devices.

Samsung has stated that their current focus for the new Galaxy S4 will be a full HD 1080p display, with no implementation of a flexible screen as the technology is “not currently up to standard” according to a Samsung expert in the field. The Samsung Galaxy S4 will have a 1920x1080 display that is there to compete with other phones on the market.

There had been speculation over the recent weeks that Samsung would release their new S4 handset with a flexible screen but Samsung have now officially stated that, their progress with the flexible, foldable and bendable screens has not been good enough to put it on their highly anticipated device.

A Chinese forum has posted pictures of what looks like the new Samsung handset, the Galaxy S4 ahead of its official launch in the New York on the 13th March with the poster claiming that this is a dual-SIM version of the phone.
