Hi there, I just got the OTA KitKat update and I can't seem to figure out why the OK Google hotword detection isn't working from the home screen. I read previous posts and made sure that the English language is installed, it is pre-installed for me and also that it was enabled. I tried both search widgets but neither of them has the text that says "Say OK Google to search" or whatever it says. Any ideas? :-\
Edit: Looks like resetting my system settings fixed it. When the phone booted back up it asked which launcher to use and gave me the option of the Google Now Launcher. All is well again.
