Samsung wasn’t kidding when it said the Galaxy S6 would be unlike any other Galaxy smartphone on the market. Just about every feature on the device is an upgrade from the previous model; there is no confusing the Samsung Galaxy S6 with the Galaxy S5.

The sixth generation device is Samsung's attempt to recapture the market, in which it has suffered significant sales drops in the last year. After being criticized for releasing a host of smartphones that were too similar to one another, Samsung started from scratch, and code named the Galaxy S6 "Project Zero." That project, the Galaxy S6 and Galaxy S6 Edge was unveiled Sunday at the Galaxy Unpacked press event in Barcelona, Spain. The event precedes the World Mobile Congress, which starts Monday.

The competition among premium smartphones is at an all-time high. Having noticed the how crowded the smartphone market has become, the Korean manufacturer set out to make the "best in class smartphone with the best in class design," Samsung President and CEO J.K. Shin said. The Galaxy S6 and Galaxy S6 Edge include a host of features, which Samsung said it hesitated to introduce until it was certain the features worked well and would be valuable to consumers.

Check out the preliminary details for both devices.
