Sammobile, after speaking to anonymous insiders, reports that the South Korean mobile manufacturer intends to unveil the Samsung Galaxy S4 Mini this week itself. The market release of the S4 Mini is expected by the end of May or in the beginning of June.

Like the Galaxy S4, its smaller version is also expected to come in two colour variants: Black Mist and White Frost. Additionally, the handset will be available in single and dual-SIM variants. The S4 Mini will carry a model number of GT-I9190 whereas the dual-SIM version will be codenamed GT-I9192.

The Galaxy S4 Mini is rumoured to feature a 4.3in qHD display. It will run on Android 4.2.2 Jelly Bean and have the new TouchWiz Nature UX user interface. It will have an eight megapixel rear-camera and support Wi-Fi and AGPS.

The single SIM-card variant of S4 Mini will be powered by a quad-core processor and the dual-SIM version, dubbed as Galaxy S4 Mini DUOS, will use a dual-core processor.

Details about the S4 Mini have come out following confirmation of the proposed launch of the new device by a top company official. "The Galaxy S4 does not come out until late April. It is fast, has a big screen, and will probably be another huge hit for Samsung, as will the S4 Mini that will go on sale soon after," Lee keon Hyok, senior vice president at Samsung Electronics has been quoted saying.
