(Telecompaper) Samsung Electronics saw its fourth-quarter profit jump 76 percent to KRW 7.04 trillion from KRW 4.01 trillion a year earlier. Sales rose 19 percent to KRW 56.06 trillion. The mobile communications division was the main contributor, growing sales 58 percent to KRW 27.23 trillion. The growth was mainly driven by solid sales of the Galaxy S III and Galaxy Note II. For 2013, Samsung expects intensified competition amid smartphone growth slowdown, and for the tablet market, the company foresees more competition as well as strong growth with emerging market expansion. Profitability of the network and IT division decreased due to intensified price competition, while sales of LTE equipment and notebooks in overseas markets increased. At the semiconductor division, sales grew 5 percent year-on-year to KRW 9.59 trillion due to the differentiated product mix but memory sales were down 2 percent to KRW 5.33 trillion. The consumer electronics division saw sales slip by 1 percent to KRW 13.95 trillion and display panel sales fell 9 percent to KRW 7.75 trillion as TV panel sales declined.
