Note 7 Home button, edge, and notification bar disabled?

[AC Question]

My (not yet returned) Note 7s "return to home" function via home button, notification bar, and Edge feature seem to be disabled. The home button works to wake but won't be used for a return to home function. The notification bar will pull down but only show the 5 top functions and won't show notifications. Edge is completely gone and won't return. I've tried many things and nothing seems to do it. Anyone else have this problem? Any feedback helps. Thanks!
