Prevention Information


Prevention Information

Starting yesterday I started revcieving a notification that states

"An application has been forced to stop for an unauthorized attempt to access system in your device.  It may be safe to delete an application obtained from an unauthorized route.  Check now?"


I have not installed or updated anything recently. 


Its coming from Knox Notification Manager and doesnt give the name of  the app causing the problem.  I have no access to knox so how do you fix this and what app is it that is causing the problem?


I believe this is from samsung hub's update not being supported on my device.  Help?

Re: Prevention Information

You know, there are a number of us with the same issue, searching the issue on google, possibly hundreds of us are having this issue.


Why not post support infor here, or at  least on the FAQs?  It would be a lot faster than the hour or more it usually takes me when I have to get on the phone with ATT support, not even mentioning the odds against recieving a call at a time I can sit around and mess with the phone for an hour, or the difficulting in trying to troubleshoot a phone while I'm talking on it.
