Samsung initially said Knox would launch on the Galaxy S4, which is to arrive in AT&T stores on 27 April. But two people working with Samsung on Knox said Samsung had decided to delay the release because it needed more time to test the software internally and with carriers. Samsung informed one of these people that Knox would be out around July.
Samsung’s spokespeople confirmed that a full version of Knox would not be available until a later date. "All the Knox framework components come standard on the device, with full-feature activation by solution providers and distribution channels to become available at a later date," the company said in a statement.
