Samsung is rumoured to be about to capitalise on the public popularity of its Galaxy S4 smartphone by further expanding the family to include a variant focusing more on the camera side of things.

Dubbed the Samsung Galaxy S4 Zoom, the new phone will reportedly join a line-up of additional devices named the Samsung Galaxy S4 Mini and Samsung Galaxy S4 Active, with the latter being the waterproof, more rugged handset revealed by a company executive during the recent Dubai launch of the conventional S4.

SamMobile claims that the Zoom, codenamed SM-C1010, will have a 16-megapixel camera; the recently released S4 has a 13-megapixel sensor. The site states that the sensor on the new camera-centric smartphone will be similar to that in the Samsung Galaxy Camera, released at the tail end of last year.

This won't, however, make the S4 Zoom a premium version of the existing model. The screen size, says SamMobile, will drop from 5-inch to 4.3-inch. Additionally, it says it hasn't yet found out if the processor will be quad-core, like the UK and US editions of the S4, or just dual-core. There are no mentions of the octa-core processor sported by the non-LTE versions of the Galaxy S4.

The touted release date for the Samsung Galaxy S4 Zoom is June or July, and it will come in black and white colour schemes, it is said.
