Android Question How to know if the phone has the central button?

[Matteo Granatiero]

Because the phones that do not have the central button have this menu that I attach in photos (taking up space of the display) and creating problems with the layout of the app.
So my question is how to know if the phone in which the app is installed has or not the central button.
