Samsung disclosed on Friday that its overall operations in the three months leading to end of June netted $US5.9 billion, 70 per cent of which contributed by its Galaxy smartphone product lines.

While its second quarter income for 2012 failed to surpass the earnings' of Samsung's fiercest rival, Apple, in the same period, the figures were good enough for the Asian tech titan to keep the multiple titles it snapped earlier this year.

Samsung has become the biggest mobile phone maker in the March quarter, ending Nokia's more than a decade of rule in the market, while at the same time it bested Apple as the smartphone king, with the company's wide-array of smartphone models getting the best of the iPhone.

And the most important distinction is Samsung has sustained its reputation as the top tech firm in the revenue department, its 79 per cent in operating profit pushing its present value at around $US160 billion, according to Reuters.

However, Samsung said not all its business concerns were signalling positive indicators, quickly clarifying they were not losing profits in other divisions but merely witnessing slowdowns, especially in the PC components business, where the company is among the chief global supplier of dynamic random access memory (DRAM) module.

Besides that, Samsung said that it sold enough units of LCD televisions and flat panel parts for the divisions to register considerable earning in the June quarter.

Also, the company's telecom business further in the last quarter as it spiked by more than a hundred per cent in the period mainly due to the estimated 50 million units of smartphones that Samsung sold.

Those numbers totally dwarfed the 26 million iPhones that Apple reported it sold in the same amount of time and Samsung has the Galaxy S3 to thank for driving up most of the global consumer interest on its handsets.

Media reports said the iPhone competitor shifted more than six million units from the day it was released in late May through the end of June and went on to sell past the 10 million mark by the end of July, according to figures provided last week by Samsung mobile division chief Shin Jong-kyun.

The past two quarters have been so overwhelming that Samsung believes its September performance will not be any different and will in fact exceed expectations, with analysts noting that viable competitions were nowhere to be found until that moment.

Apple, based on speculations and reports, will not release a new iPhone until middle or late October, which coincides with the expected debut of Microsoft's Windows 8 smartphones.

But experts said the new market entrant, the Windows phone, is not primed to make a major dent in the industry until a few quarters due to insufficient ecosystem support.

With such rosy horizon ahead, Samsung said it remains for than upbeat for its overall prospects in the upcoming period results.

"The third quarter is expected to be marginally positive as demand for consumer electronics goods, including smartphones and tablets, remains strong and a stream of new products hit the market. Supply for display panels is also expected to increase, as TV makers prepare for the year-end holiday season," The Associated Press (AP) reported Samsung as saying in a statement on Friday.

Samsung's mobile business alone would shore up its chances of hitting $US7 billion in profits by the time the company issues its new quarter report in October, Reuters said in separate report.

And those numbers will be underpinned by Samsung's surging mobile phone sales, which jumped by more than a hundred per cent in the past 12 months, plus the steadying LCD television global market that previously was hampered by the financial crisis battering the major economies in Europe and partly in the United States.
