BlackBerry has been put on notice as well, Llamas said, since dual-personality features are included in the S4 because of Samsung's introduction of Knox technology based on SAFE (Samsung For Enterprise). With the dual-personality approach, a worker can safeguard company data on a separate area of the S4, something the BlackBerry has included in the Z10. The Z10 goes on sale in the U.S. next Friday through AT&T.
Samsung said the S4 will go on sale in the U.S. sometime in the second quarter, and on 327 carriers in 155 countries at the end of April. AT&T, Sprint, T-Mobile USA and Verizon Wireless will carry it, Samsung said, and Sprint confirmed it will have it in the second quarter. Pricing has not been announced, but analysts presume it will sell for $200 with a two-year contract.
In addition to gesture capabilities, another unusual feature allows the 13-megapixel rear camera and the 2-megapixel front camera to be used simultaneously during a video chat, with the two images presented within windows.
The S4 is slightly slimmer and lighter than the GSIII, although both look much the same. The S4 is 5.38 x 2.71 x 0.31 inches and weighs 4.6 ounces. It will come in black or white.
At a glitzy event at New York's Radio City Music Hall on Thursday, Samsung unveiled the Galaxy S4 flagship smartphone.
