In fact, the division's operating profit slid down from a healthy 6.43 trillion won ($6 billion) for Q1 2014 to only 2.74 trillion won ($2.6 billion) for Q1 2015.  Samsung clearly needs a compelling product to compete with Cupertino's iPhone sales, and the South Korean corporation believes the new Galaxy S6 and S6 Edge are the answer.  The company expects an increase in global earnings by selling 23 million S6 and 23 million S6 Edge units this year.  It seems to be struggling to keep up with the demand for the wraparound screen version of its new flagship, but it did promise to "resolve the difficulty in supply." 

Outside the mobile division, Samsung's semiconductor business continues to flourish, with an operating profit of 2.93 trillion won ($2.7 billion), up from last year's 1.95 trillion won ($1.8 billion).  The Display Panel division's also doing well thanks to an increasing demand for UHD TVs, earning a 520 billion won ($490 million) profit that's much larger than last year's 80 billion ($75 million).
