Unfortunately, details on this new smartphone UI from Samsung are missing. But we can spot a Magazine icon, which leads us to believe that the new UI is related to the new Magazine UX that debuted yesterday on Samsung's 12.2-inch Galaxy NotePRO. Overall, the UI looks simple and elegant. Sure enough, there's no way of telling if this will ever make it to a commercial smartphone. But we're thinking that the rumored Galaxy S5 - expected to be officially announced in the next few months - can have a fresh look with a UI like this.
Until we hear more on the matter, take a peek at the screenshots below and let us know what you think about this new possible Samsung UI design.
Update: We must mention that this looks like an early prototype of the UI.
