Samsung Electronics Co Ltd is under mounting pressure to produce eye-catching new smartphones after its mobile business shrank 3.5 per cent in the second quarter, taking the gloss off a record $8.5 billion operating profit.
The South Korean IT giant on Friday said April-June operating profit increased 47.5 per cent from a year ago to 9.53 trillion won, in line with its estimate.
Profits at its mobile division, the biggest earnings generator, jumped 52 per cent to 6.28 trillion won from a year ago but fell 3.5 per cent from the previous quarter.
The reporting period included the launch of its flagship samsung Galaxy S4 in April, backed by a massive advertising campaign, in Samsung's biggest assault yet on arch rival Apple Inc's iPhone.

Samsung said its 2013 capital spending would rise by more than 1 trillion won to 24 trillion won this year from 2012, joining rivals seeking to boost output. It said it may further increase investment depending on market conditions.
The world's biggest maker of memory chips and televisions also said profits from its chip business rose 71 per cent to 1.76 trillion won on the back of soaring prices for semiconductors used in personal computers and mobile devices.
Shares of Samsung have lost 14 per cent or 32.7 trillion won since early June, hit by a series of brokerage downgrades as concerns mount that its handset margins may drop on weakening sales of the S4 and slowing high-end market growth.
Apple on Tuesday reported stronger-than-expected iPhone sales, easing investor concerns that growing competition is hurting demand for its top-selling product.
But its quarterly profit fell 22 per cent and gross margins slid below 37 per cent from more than 42 per
