A new rumor suggests that the company may unveil its Galaxy S5 on Feb. 23 just before Mobile World Congress, although the phone isnt expected to hit store shelves until April. The tip comes courtesy of Eldar Murtazin, editor-in-chief of Mobile-Review.com who has been known to leak Samsung information in the past. Murtazin posted to Twitter that the phone will be announced in Barcelona on Feb. 23, adding that a new TouchWiz UI is in tow and pricing will remain the same as Samsungs previous flagship.
