Galaxy Note 4 "Menu" icon after pressing volume up button

[Android Central Question]

Hi all, my grandfather has a Note 4 and whenever he presses the volume up button, a menu icon populates at the top of the screen. It seems to be related to accessibility, but nothing under the accessibility menu is sleeted. Any advice would be helpful. Thanks!
