How can i get that little man in the square to pop back up on my phone? (Acatel Pixi 4 6'')

[Android Central Question]

I remember having the square on my screen, I turned it off and don't know how to fine the option to turn it back on.. My home buttons no longer work at all.

Welcome to Android Central! What function did that icon serve? What do you mean your home buttons no longer work? Are you talking about the Home, Back and Recent Apps buttons along the bottom?
