Smartphones will only get bigger in the next few years because consumers are embracing the trend, Samsung said, hinting too that its current success rides high on the level of satisfaction the company delivers to global gadget users.

Testament to the South Korean tech giant's incredible achievement is the $US8.3 billion operating profit it realised in Q4 2012, based on the firm's preliminary reporting, which was backed by indications from Daewoo Securities that Galaxy smartphones were snapped up by at least 62 million consumers worldwide.

For the past six quarters, Samsung undoubtedly is the boss among the giant device maker, besting even the company that started all this excitement, Apple.

So what is the secret of Samsung's success and how far is the company willing to go in stretching the mobile phone's screen size and entrance the world?

Samsung is now an Asian tech juggernaut, according to Farhad Manjoo writing for Slate.com, because it was willing to challenge the seemingly unstoppable rise of Apple a few years ago, when iPod, iPhone and iPad were practically waylaying the competition.

Samsung braved the global Apple hurricane by figuring out that global consumers outside of the iPhone and iPad sphere are willing to pay for, Mr Manjoo said.

"By giving people what they wanted - even if it meant copying Apple - Samsung had become a global gadget powerhouse," he added.

And the company was willing to gamble and face ridicule. When it launched the Galaxy Note, critics were like: "What Samsung was thinking?" The Note was outrightly dismissed to head for oblivion. Yet the smartphone, now called phablet, generated phenomenal reaction and racked up more than 10 million of global sales and counting.

It was also refreshed via the Galaxy Note 2, which found more success, which convinced the firm to further push the envelope, indicating too that its future offerings will only be limited by buyers' reception.

There will be more giant screen phones to roll out from Samsung's production lines, according to Nick DiCarlo, who heads the company's product planning division, adding that "we know, and we've proven very effectively, that consumers like big-screen phones."

In an interview with PC Magazine, Mr DiCarlo acknowledged that rival manufacturers are noticing the rise of Samsung's phablet initiative and are issuing Note challengers. He maintained, however, that the Note's unique flavour will keep it on top of the food chain.

"Ours has the S-Pen ecosystem: the pen, the digitizer, the SDK and the apps ... We have more work to do to make that ecosystem as good as it can be," the Samsung executive told PC Magazine.

For the next two years, Samsung is not only gunning to improve on its devices' hardware and software specs but also to deliver the best experience possible that users can draw from the gadget of their choice.

Putting into perspective the prevailing trend in the mobile device industry, Mr DiCarlo pointed to Samsung's flagship smartphone, the Galaxy S3, deemed as too much of a widescreen when its 4.8-inch screen debuted to tussle with the iPhone 4S, iPhone 5 and other Android handsets.

Now, save for the Apple smartphone, the rest are stretching their screens too and all of a sudden "the funny emotion for me now is how small the Galaxy S3 feels," noted Mr DiCarlo.
