A Russian website hi-tech has revealed the specifications of the speculated two Galaxy S4 variants - one camera-centric model, Galaxy S4 Zoom, and another rugged-version Galaxy S4 Active.

The website claims that the Galaxy S4 Zoom will sport a 16.0-megapixel camera with 10x optical zoom at the rear side and 1.9-megapixel camera, and it will feature 4.3 inch Super AMOLED screen with qHD 540x960p display resolutions.

It will run on Android Jelly Bean OS powered by a 1.6GHz dual-core processor and standard connectivity features such as Bluetooth v4.0 and Wi-Fi (802.11 a/b/g/n).

On the other hand, Galaxy S4 Active, which is expected to feature a rugged body case with water-proof and dust-resistant capability, will sport a 5.0-inch Super AMOLED Full HD display and it will run on the Android mobile OS v4.2.2 Jelly Bean powered by Qualcomm Snapdragon 600 series quad-core processor with Adreno 320 graphics engine.

According to reports, Galaxy S4 Active and Zoom are expected to get unveiled at the 'Samsung Premiere 2013 Galaxy & Ativ' event to be hosted by the company in London on 20 June.

Along with two new variants, Samsung is also reportedly set to showcase the Galaxy S4 Mini at the event. It was unveiled only a couple of days ago.
