The South Korean company has sent out invitations to a February 24 event in Barcelona. Samsung looks set to be taking the wraps off its latest flagship smartphone on the first night of this years Mobile World Congress. Although the companys existing premium handset, the Galaxy SIV, is one of the most popular in the world in terms of sales, it hasnt had quite the consumer impact that Samsung had hoped. Indeed, in a recent interview with Bloomberg, Samsung executive Lee Young Hee accepted that the SIV wasnt as big a hit as it could have been because it wasnt sufficiently different from the handset it replaced and that the company wouldnt be making the same mistake again.
