Despite the fact that there has been no official disclosure from Samsung about the announcements it will make at its March 14-scheduled event, there are speculations galore that the company will likely introduce its next Galaxy handset - the Galaxy S4 - at the forthcoming event.

In an indication that Samsung's highly-guarded secret about the much-speculated Galaxy S4 announcement at the event - which will be held at the Radio City Music Hall in New York on March 14 - is continuing to leak out, an almost completely dark image showing one corner of the rounded-edged Galaxy S4 in profile was tweeted On March 12 by @SamsungMobileUS.

Though not much can be gathered about the handset from the dark image, there are still apparent indications that the Galaxy S4 will be fairly akin in appearance to the Galaxy S3.

Earlier too, images posted to Chinese user forum 52 Samsung this week had hinted that the Galaxy S4 will bear a striking resemblance to its predecessor. The pictures posted on the forum showed a handset which looked like a bigger version of the Galaxy S3, and featured a pattern or possibly texture in the back paint.

Moreover, a March 3 leak from an Android developer suggested that the key features of the Samsung Galaxy S4 - which will run the Android OS version 4.2 `Jelly Bean' - will include a 5-inch Super AMOLED screen with a resolution of 1080p HD; an 8-core processor; 2GB of RAM; up to 64GB storage capacity; and a 13-megapixel camera.
