It isn't clear if Samsung will be replacing all BlackBerry units now used by the FBI, or whether some 'Berry phones will remain in use. The FBI did not offer a comment. Another published report late Thursday said that Samsung was working on a similar, albeit smaller deal with the U.S. Navy.
Samsung has developed a layer of software that runs on top of Android that allows certain business-style applications to run securely. But according to Rob Enderle, principal analyst with Enderle Group, despite the use of the Samsung Knox software, Android is not a secure system. In a letter to the FBI, U.S. Representative Kenny Marchant of Texas said he was concerned about the FBI using Android with Knox on top. In his letter, the Representative said, "I understand that the FBI may be considering a new solution that is a patchwork of technologies stitched together. I am concerned that this approach may prove to be more costly than other alternatives." In May, the Samsung Galaxy S4 received Defense Department security approval, something also received by BlackBerry 10.
