Sony Ericsson's chief executive Bert Nordberg has said that the company, which is a joint venture between Japan's Sony Corp. and Sweden's Telefon AB L. M. Ericsson, would become a complete smartphone manufacturer by the mid of 2012.

In an interview with WSJ, Mr. Nordberg said that the company had been closing down low-end phone business to build up a complete smartphone business.

Speaking on the topic, he said, "By now, some 70% of our sales stem from smartphones and some time in the middle of next year, I estimate that we will be a complete smartphone company."

He also said that they were quite cautious in introducing new technologies in their handsets as there was no guarantee that consumers would purchase them.

Since his appointment as the chief executive of the company, Mr. Nordberg took many radical decisions to boost sales, such as he ditched the Symbian platfrom and moved to Google popular Android operating system.

But, the company share in the global handsets market has declined from 4.3 per cent to 1.7 per cent since his appointment. Sony Ericsson reported another loss for the most recent quarter as the earthquake & Tsunami in Japan hit its component supplies.
