Feature: Samsung aims to charm Taiwan with Anycall Studio

The output from Gumi will rise to 75 million units this year from 69 million last year.

It is also considering several locations, including Vietnam, for its next overseas handset plant, adding to the current facilities in China, India and Brazil.

The next growth momentum will come from emerging markets, including China, India and Africa, Roh said.

"Users in these markets need lower-end phones. When we launch such products, we will add differentiation to our low-end phones to make them stand out," he said.

But industry watchers said competition is fierce.

"Samsung's Ultra edition phones are well received but rivals like LG or Motorola also focus on slim phones," Fox Su (蘇昱霖) of the Topology Research Institute (拓墣產業研究所) said. "Any mistake in the product mix could cost a maker dearly."

However, Lee is convinced that Samsung phones will continue to enjoy high popularity.

"Handsets are no longer merely a communication item. We create brand originality in our phones by adding the element of sensibility'," Lee said.
