Found this strange misspelled cert in the user cert s. I was experiencing problems and overnight hacking into my tablet. A proper cert already existed this seemed redundant and possibly the source for the unauthorized access. I ran a query and found a few hits were others found the same and deleted it, so I deleted it. Some posts say Knox is Samsung's main security software but I can't substantiate that. Can anyone assist? I lost Twitter update ability and probably other functionality I haven't found yet. Is the misspelling a normal occurrence? I thought the "hac" in the misspelled word to be rather ironic. Any assistance would be greatly appreciated.
