mobile

First I'd like to say I love this site and my first post whooo! lol. I have used it for several months and finaly got to the point where i might as well been an active member. (also I'm getting pretty decent at this stuff and figured I could help some of the beggener questions)

Ok so My wife plays clash of clans and i finaly talked her into letting me root her phone so she could use xmodgames with it.
come to find out with the phone being on Android 5.0 the S5 is one of two phones that wont work with xmod (S5 and Note 3) because of SeAndroid Enforcing. So I found and flashed a Kernel for her phone that is set to SeAndroid permissive. Which is great it worked. But now there is a constant notification stating "Security Notice" There is an unknown process which can harm blah blah blah. you know the usual Samsung "Don't do it stuff"

Is this being produced by Knox? if so will using a terminal emulator and the "pm disable com.sec.knox.seandroid" work to make that stop? and will adb work for that command? ( I've found especially with samsung devices that using a computer for everything has saved me a headache.

if not, i'm just theoryizing here but could I do an adb log and watch it and wait for the notification to come back up ( its like 30 seconds after you remove it) then stop that process?

thanks for your help guys.
