Can't find Google enhanced services options anywhere on Note 8

[sknole]

Just gonna give an update that I had the same issue one the Galaxy S9+. I disabled Bixby and Google Enhance Services was set as the default assistant automatically, but the "okay google" options were grayed out. I fixed it by going into Settings>Advanced Features>Device Assistant App and changing the device assistance app to "none" and then changing it back to "Google Enhanced Services". Then it came up with the voice training for the google assistant. I guess it doesn't set properly when you disable the Bixby assistant.

I know this thread is for the Note 8, but it is one of the top results when I'm searching for this issue on the S9+. I hope this helps anyone else with this problem.

Thanks. This solution worked perfectly on my S9.

SN: my phone is always in ‘mid’ power saving mode, so battery saving mode isn’t the issue.

I was having the same problem. It is very simple. Uninstall the Google app from the app store. Reinstall it and it will automatically start prompting you to register your voice after you click on settings, voice and choose to turn ok Google on. Then you are all set. Don't worry about Google enhanced voice service, it doesn't exist on the note 8 anywhere in any settings menu

Here is the solution:
Go to settings > Advanced features > Device assistance app > Device assistance app "Change it from None to enhanced Google services"

You will see that the option to turn OK Google on is available now, so basically you need to turn on the option that holding the home button opens google assistant for ok google voice to work.

I had the same issue too although ok google voice recognition is horrible on my S8. Hope that helps
