A couple of days ago, a few pictures of what was allegedly the Chinese variant of the Galaxy S4 made its way on the Internet. Today, a video of the same Chinese variant of the SGS4 has surfaced online on a Chinese forum giving us a sneak peek of what the Galaxy S4 might look like and its TouchWIZ UI.
While it is not confirmed whether this is the final variant of the Galaxy S4, the device in question does sport a design language similar to the Galaxy S3. The video also confirms that the Galaxy S4 will be having a microSD card slot along with a beefy 2600mAh removable battery.
The latest version of TouchWIZ UI does not seem to look that different from the current nature inspired version found on the Galaxy S3 and Note 2, but does have a new white color scheme. The white color of the UI may suggest that Samsung is using a different form of OLED technology or maybe even an SLCD, since AMOLED displays are not that battery efficient while displaying white elements on screen.
It might very well be possible that the above device in question is one of the prototypes of the Galaxy S4, and the final device may look completely different.
