Interesting, there must be something wrong with my root then. My note 4 is rooted and private mode works well with it rooted and knox is tripped.
My note 4 has android 5.0.1 so maybe that has been fixed in this version. One thing that does bother me is my kids have got note 4 and I would like to lock it out for their safety and my peace of mind. It seems for some reason the monitoring software I have installed (I know spying on kids, tisk, tisk).
Now the problem I am having is it has been excepted in the anti-viral, I allow google to accept unknown software. So question is is it google or android (knox) that has locked it out, or does anyone know a work around?
