What do you use the google search bar in android home page for?

[mustang7757]

I just moved the bar to the second home page, and I notice I need to swipe my home page to the second home page that the bar is on, then when I speak "hey google" it will work.

I can long press and remove icon from home too.

Any idea how to let it work like normal after removing the bar? And when I am not at the home page that the bar is? (I mean like if i say hey google it will still work.)

Just enable hot word "hey google" should work anywhere
