I am a My Knox user and like the rest of you guys I received the End of Life notice. Samsung is positioning Secure Folder in the place of My Knox. For the uninitiated, My Knox is a secure container that helps separate work and personal stuff for BYOD applications. With your password, fingerprint, etc. you unlock a folder or launcher and you can remote access your phone to locate, lock, unlock, or wipe it. Secure Folder functions are almost the same but you lose a few features.
