I have yet to decide on a ROM for this phone yet. I am running stock ROM which is rooted with CWM Recovery. I understand a little regarding the "KNOX" implementation of security that seems to block hotspot tethering. I thought my SUPERUSER got rid of it but I still seem to have it. My question is, IF KNOX IS THE PROBLEM, is there a a way to get rid of it? (I have heard about manually deleting KNOX files but not sure if that is completely safe). I have not been able to get any WIFI Tethering APP to work. I have tried pretty much all them. Am I just going to be forced to install a custom ROM at this point? Thanks in advance for your comments.
