Knox is an extra layer of containerized security between your phone and other devices for the transfer of data. That's the official definition, actually its written by the NSA for Samsung. Can you say SPYWARE? This info is right off the Samsung website.

I run 4.4.2 NC5, stock, rooted, with Philz custom recovery. I disabled and removed KNOX, and flashed Philz recovery ( which voided my warranty the second day I owned the device ). They are working on a way the reset KNOX warranty counter.
OK, if you root your phone with Towelroot it will NOT trip the KNOX warranty counter. Here is the link https://towelroot.com/
this will give you the ability to run certain apps like WiFi Tether Router that needs root.
Now, if you flash a custom recovery ( highly recommended and needed if want to flash other roms ) here is the link to PhilZ CWM recovery http://forum.xda-developers.com/show....php?t=2201860
I would use hltespr version 6.12.9 .tar this is the latest Sprint version. This will definitely trip the KNOX warranty counter. But think about, did you root your phones in the past? I have, and Sprint never gave me a problem with the warranty.
The Note 3 is an awesome device !!! Enjoy !!!
