'Ok, Google' crippled

I think Samsung should stop wasting their time with S Voice. It was nice when Google's was not around and then just released, but it is among the many duplicate features that really aren't needed.
 
Looks like Samsung may have crippled some aspects of 'OK, Google'.:See here: :-\
Did you know: 'Ok, Google' voice command comes crippled on Samsung's Galaxy S6, S Voice promoted instead

Yeah there's a few threads on that here. The option to have it always on was there when the phone was first released but then Samsung sent an update through and disabled it.

You can add the Google widget to any screen that you like and 'OK Google' it will work as long as you are on that screen.
