Samsung Galaxy S4 to be unveiled on March 14 London - Arabstoday Leaked images showing the eagerly awaited Samsung Galaxy S4 smartphone, have appeared online - a week ahead of its proposed launch in New York. The pictures, if legitimate, confirm several of the widespread rumours about the forthcoming phones specifications, particularly the upgrade to a massive 5in screen. The handset, dubbed 'GT-I9502', is apparently customised for Chinese carrier Unicom. It is said to have a 'Universal5410' 1.8GHz processor, 2GB of RAM and a PowerVR SGX 544MP graphics processor. The images were uploaded to Chinese forum 52 Samsung just hours ago and were quickly picked up and republished by respected tech site The Verge. A reporter for the site says the Universal5410 is probably a codename for the Exynos Octa 5410, an eight core processor which has been widely speculated to be at the heart of the new Galaxy. The pictures also that the new handset is broadly similar to the last-generation Galaxy, complete with oblong home button. Another hotly anticipated feature of the forthcoming handset is Samsung's patented 'eye tracking' system, which will allow users to automatically scroll through webpages by simply casting their eyes across the display. “The phone will track a user’s eyes to determine where to scroll”, a Samsung employee told the New York Times. Speculation is also mounting that the new device will feature an impressive 1920x1080 display as well as a 13MP camera, in a bid to outdo Apple in the smartphone wars. Mocked-up graphics put together by mobile phone retailer Expansys based on the widespread rumours have shown how the S IV could match up to previous incarnations of the Galaxy device. However, The Verge sounded a note of caution over the latest set of apparently leaked photographs, reminding readers that the S4 was leaked several times in dummy casings that concealed its actual design. “While this leak doesn't have a visibly-fake outer shell, there's every chance Samsung could've crafted a false casing for testing purposes — just as there's every chance this could be an elaborate hoax,” the site reported. Meanwhile, Samsung Electronics' mobile division chief JK Shin told South Korea's Edaily news website that the decision to launch the new smartphone in the US was spurred by demand from mobile networks. “We introduced the Galaxy S3 in London last year, and this time we changed the venue (to New York)... as we were bombarded with requests from US mobile carriers to unveil the Galaxy S4 in the country,” he said.
