I have been a BlackBerry user for years....I am considering moving to the Galaxy S4 at the end of the month....I am not an Enterprise user nor do I own a PC, all of my communication, browsing and financial activity, etc. is done via the Smartphone. I am concerned about Android security but have read about Knox. Does this app offer improved security for a private user such as myself? I am new to this forum and attempted to find an answer before posting but could not find what I am looking for thanks for any assistance you can provide
