Why aren't my overview and home buttons working?

[Android Central Question]

The back button works, and I can see the little response thing when I click on the buttons, but it doesn't do anything besides that. I'm on an Elipsis tablet, and have tried resetting it multiple times.

Welcome to Android Central! What do you mean by the little response thing? Does the screen respond to any touch at all -- for example, swipe down the notification panel, or swiping to a different homescreen?
