At a Thursday event in a London exhibition hall, South Korean device manufacturers Samsung Electronics unveiled a number of devices, including the Galaxy S4 Mini handset; two new ATIV tablets; and the upgraded version of its Galaxy NX camera.

The unveiling of the new devices by Samsung comes amid concerns about the lower-than-expected sales of its high-end flagship handset, the Galaxy S4; and underscores the company's attempts to increase its mobile-device market share.

The Galaxy S4 Mini handset unveiled on Thursday is a cheaper, stripped down version of its Galaxy S4 smartphone. While the handset is apparently aimed at consumers in emerging markets, the cost or availability of the device has not been disclosed by Samsung as yet.

Other than the Galaxy S4 Mini, Samsung also refreshed its ATIV lineup, with the launch of a 10.1-inch, 8.2mm ATIV Tab 3 tablet, which is being touted as "the world's thinnest Windows 8 tablet"; and the 13.3-inch ATIV Q tablet which is capable of running both Windows OS and Google's Android software.

Apart from smartphones and tablets, Samsung also launched the latest version of Galaxy NX camera which is a Web-connected camera that comes with an interchangeable lens.

Meanwhile, describing Samsung's launch of an array of new devices as an 'all things to all people' strategy, Sanford C. Bernstein's senior analyst Mark Newman said that such a strategy covers "every possible product size and type possible to capture as many customers as possible."
