I thought that is a solution for that but I cannot find it. I know that I can disable back button by overriding onBackPress() method and not call super.onBackPress() but it only disable, I want to remove/hide from navigation bar this button.

And I known that on some device where the back button is a part of hardware it can be done.

To be clear I mean arrow on below screen:

You can find solution in the documentation.

View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
              | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

and this code should be placed in onCreate() method in the Activity after initializing all UI elements.
