Samsung has lifted the lid on its plans for Tizen, after Yoon Han-kil, senior vice president of the Korean firm’s product strategy team, said that it will launch smartphones running the Linux-based mobile operating system during its second quarter of business in 2014 — which runs April-July. Tizen-based devices were originally scheduled to go on sale last year, but Yoon admits that the company aborted launches in Europe and Japan “because of poor market conditions”.
