The Galaxy S4 follows on from last year's S3, a product that sold over 40 million units worldwide.
The device was unveiled at a lavish, Broadway-themed event in New York.
Technology analyst Carolina Milanesi, from Gartner, said the key to its success would be whether its novel features would be of use on a daily basis.
