I cannot get to the settings screen on ellipsis 8

My grandson turned on the voice assist(?) on his tablet - Ellipsis 8. I now get green boxes that must be double tapped to do anything. I need to get back to Settings to turn whatever he turned on - off. However when I tap on the Apps Icon, it will only give me page 1 of 3 and the settings Icon is on page 2. How do I get to the second or third page? I keep tapping on the three little dots but nothing happens.

Thank you for any and all assistance.
