hello , please help, i cant get rid of a popup saying (se for android is disabled,please tap here) , i got a samsung galaxy prime, and when i long press this notification for app info, its directing me to "knox notification manager' if you force stop it,it keeps popping and popping again, please help me its really annoying T_T

Hi, I have been reading a lot of stuff about this problem and the only solution for me was to get root access with the app "Kingo ROOT", then to install "Titanium BackUp Pro" and to freeze all Knox apps.
You can try, it works for me :)
