Today's report states that one reason for the price hike could be the new iris scanner that Sammy plans on stuffing into the entire Galaxy S7 line. With the iris scanner on board, a steely stare at your Samsung Galaxy S7 should be able to unlock the handset, verify your identity, and basically do all of the things that a fingerprint scanner can do. Because everyone has unique patterns in their eyes, the iris scanner is the most precise type of biometrics available
Recently, we passed along to you images of some new cases said to be made for both the Samsung Galaxy S7 and the Samsung Galaxy S7 Plus. One of the photos contained an image that was claimed to be that of the Galaxy S7, which will apparently include a rectangular home button. The Galaxy S7 should be unveiled on February 21st, the day before MWC opens in Barcelona, during the Samsung Unpacked 2016 event. And a leaked road map showing China Mobile's upcoming handset launches reveals a March release for the Galaxy S7.
With this report in mind, we could see the Samsung Galaxy S7 carry a retail price above $700 at the time it is released in the U.S.
