Tech analysts said over the weekend that South Korean giant Samsung's latest flagship smartphone, the Galaxy S4, would likely continue to attract buyers, particularly Asians.

The 5-inch, full HS Super AMOLED display screen was launched in New York on Thursday, March 14, and will be sold by 327 carriers in 55 countries.

Ovum chief telecom analyst Jan Dawson forecast fast sales of the S4 once it reaches stores because it mostly meet techies' expectations of a slightly larger screen, better camera and stronger processor power and memory as well as augmented features from previous units, including the eye-tracking capabilities.

Among the specs of the S4 which would likely be appreciated by buyers is its large internal storage capacity of 64 GB plus option to expand by another 64GB through an external microSD card and its two cameras - a 13-megapixel shooter on the back and a 2-megapixal front-facing camera.

The two cameras can shoot over 100 shots in four seconds, while its S-Translator supports nine languages with 3,000 useful ready phrases.

The New York launch was just the first roll out of the S4 which has a global launch on April 26, that is quite close to the delayed launches of HTC One gadgets in some markets.

An analyst pointed out that with the top spot that Samsung is enjoying in the smartphone market, it would face similar challenges that main competitor Apple is grappling with, which is how to released better devices yearly even if their current flagships are on top of the chain and have minimal shortcomings.

It includes differentiating Samsung units from other phone manufacturers that also sell Android units such as HTC and Sony which are also improving unit specs and hardware.

However, Apple remains Samsung's toughest competitor, and this week, besides the launch and word wars, the battle ground was at YouTube which featured the new features of the S4 and iPhones. Analysts said the YouTube battle was apparently won by the South Korean tech giant.
