Samsung and BlackBerry recently teamed up with the goal of beefing up the security of Android OS.

Galaxy Smartphones to be the number one phone trusted by big businesses (just like BlackBerry was in the not too distant past).
Samsung licences a software from BlackBerry called Knox. It is Knox which will add in the extra layer of security to your phone early 2015.
