While Samsung may be keeping the Galaxy S IV a closely-guarded secret until its grand unveiling on March 14, that hasn’t stopped a number of screenshots that were supposedly taken on the device itself from being leaked. One of the images reveals the handset’s specifications, which include a 1080p display, and a 13-megapixel camera.

There’s no sign of Samsung’s eight-core Exynos 5 Octa processor, however.

The most interesting of the three screen are the second two pictured above. The one in the middle is taken from an app called Quick System Info PRO — available from Google Play — which lists a handset’s internal specifications, including its processor, its display, its cameras, and more.

According to this screenshot, the Galaxy S IV will offer a 1080p display, as expected; with an “estimated screen size” of 5.01 inches — though it’s widely believed to be more like 4.99 inches. The device also has a 1.7GHz quad-core ARMv7 processor, and a 13-megapixel camera that’s capable of shooting images with a 4128×3096 resolution.

Although this particular handset doesn’t feature Samsung’s new Exynos 5 Octa processor, it’s believed that there will be two versions of the Galaxy S IV — one with this new eight-core chip, which will ship in Europe, and another with a quad-core Snapdragon 600 chip, which will ship in the U.S.

Samsung did the same thing with the Galaxy S III — shipping a quad-core 3G model in Europe, and a dual-core LTE version in the U.S.

Another screenshot, which you’ll see on the right, also shows the handset’s new “smart screen” features, including smart rotation, smart pause, and smart scroll. The latter allows you to scroll through pages simply by moving your eyes up and down the display, and it’s also expected to come to the Galaxy S III.

You’ll also notice a slightly updated TouchWiz user interface, with a new light look.

All of the images were obtained by GSM Israel, but it’s unclear where they were originally sourced. Although we cannot confirm they’re genuine, they certainly look it, and they’re the most convincing Galaxy S IV leaks we’ve seen to date.
