SAMSUNG has published a teaser image of a new smartphone ahead of the expected launch of the Galaxy S4 on Thursday.
Samsung Mobile US published the picture on Twitter, showing a handset mostly in shadow. The update said: "The countdown for #TheNextBigThing has begun. Who’s ready for the Global Unpacked Event on March 14?"
Though the picture shows only the top of the handset, the device looks similar to leaked images published on a Chinese forum yesterday, which claimed to show the new Galaxy S4.
The leaked pictures showed a device that looked very similar to the Galaxy S3, only slightly larger. Information published on the forum claimed that the phone has a 1080p display, runs Android 4.2.1, has a 1.8GHz Universal5410 processor and 2GB of RAM.
The Verge, which first published the leaked photos, said the Universal5410 is "likely a codename for the Exynos Octa 5410, an eight-core processor with four A15 cores for power and four A7 cores for power efficiency".
The most recent leaked images do not match pictures published by SamMobile in January, which showed a similar device but without a button on the front.
Samsung's Global Unpacked Event takes place in New York at 7pm local time (midnight UK time) and though very little has been confirmed, lots of rumours have emerged about the new handset.
A video posted on YouTube today shows a similar device and the uploader claims that it is a "world first hands-on" with the Galaxy S4.
Earlier this week it was suggested that the Galaxy S4 would have a "floating touch" display, which would allow people to control the phone without touching the screen. Hovering a finger over a photo album might bring up a preview of the pictures inside, for example.
The Samsung S Pen, the stylus used with the Galaxy Note range, has a similar feature, known as Air View.
Last week it was reported that the new handset would scroll the screen based on the movement of the user's eyes, which would be tracked by the front-facing camera.
SamMobile reported yesterday that it had been told by "an insider" that the Galaxy S4 would have a PHOLED screen, which is more energy efficient than the standard OLED screen.
The site added that it expected the new smartphone to include a 13-megapixel camera and a new photography mode called Samsung Orb that will capture 360-degree images.
Other rumours have said the Galaxy S4 will have wireless charging capabilities, using the Qi standard supported by Google and Nokia, and a 5-inch, 1080x1920 pixel display with 480 pixel-per-inch density.
Samsung has not released any specific details of the Galaxy S4 but continues to tease ahead of the launch, with photos like the one published on its Twitter feed today and with a series of promotional videos.
