'Samsung has broader range of products', computer expert

Samsung accounted for one in four of all mobile phones shipped worldwide last year, as its shipments rose nearly 20% to almost 397 million units, a report by Strategy Analytics says.

The Korean company said its profits surged 76% in the last three months of 2012, helped by sales of its Galaxy smartphones.

Samsung became the world's biggest smartphone maker last year, overtaking its main rival, Apple.

Computer Weekly's Editor-in-Chief, Bryan Glick, told the BBC News Channel the firm's success was down to its wider range of products.

"Samsung have got products which can match Apple and are very popular at that high-end, but they've also got smartphones and lower-end phones that appeal to people that don't have so much money."
