Only three days are left for Samsung's March 14 Galaxy Unpack New York event, and once again images of Samsung Galaxy S4 have leaked on the Internet.

The latest leaked images bring out a different kind of feature and suggest that the South Korean tech giant is going to launch the Galaxy S4 which will support two SIMs.

The pictures were spotted on a Chinese blog 52Samsung where the description says that the dual SIM version of the Galaxy S4 is specially customized for China's Unicom and the model number of the device will be GT-I9502.

The blog also suggests that for rest of the world the device will be available in the single SIM version holding the model number GT-I9500.

The other specifications of the phone are almost same like they were revealed in earlier benchmark results.

The most recent AnTuTu benchmark showed that the Samsung Galaxy S4 will be powered by Samsung's own Exynos 5 Octa system on chip (SoC) processor. Exynos Octa 5410 CPU has eight cores and is clocked at 1.8 GHz.

A render released last month had shown the smartphone packed in a metal body with front speakers, but the latest leaked images don't show any of the features like that.

Going by the Samsung's traditional pattern of putting the physical home button, the images also show a physical home button on a curved edge case.

The display looks like a 5-inch 1080 pixel full HD Super AMOLED display. A camera, a flash and a speaker are placed on the back of the phone.  Changing the pattern style from Galaxy S3 in which the main camera was flanked by the speaker and the flash light, in the S4 picture the LED flash is place just below the camera, and the speaker is place at the left bottom on the back.

However, the benchmark results shown on the screen suggest that the smartphone might be running Android 4.2.1 Jelly Bean out of the box.

However, the pictures can just be of a benchmark test where the hardware and the system of the device are tested and not the design. In this situation, nothing can be confirmed until Samsung shows the real device on March 14 in New York.
