Samsung Electronics posted its first decline in quarterly profit in two years, hit by one-off special bonus as well as slowing smartphone sales as it braces for a year of tougher competition with rival Apple.
The world's biggest smartphone maker kept its full-year investment plan conservative and warned it would be difficult to increase earnings in the first quarter as demand pulls back from the year-end holiday period.
October-December operating profit fell 6 percent on year to 8.3 trillion won ($7.7 billion), in line with a previous estimate of 8.3 trillion won, Samsung said in a statement on Friday.

The figure was brought down by an 800 billion won ($745 million) special employee bonus to commemorate 20 years since Chairman Lee Kun-hee announced a management strategy that the company regards as the catalyst to its recent growth.
