Why did ok google stopped working randomly

[Android Central Question]

I went to say "ok google" earlier today and the google assistant didn't pop up, even though I set it up and did voice matching without turning anything off. I tried to fix it, and when I went into Voice Input, I tried switching it off Google and onto Basic Google Recognition, thinking I could turn it off and back on. Well, now the Google button is greyed out and it wont let me select it as an option, so when I go into Voice Match, the Access with Voice Match is greyed out as well as the Unlock with Voice Match. I dont know what to do. I can still talk to the assistant when manually clicking the microphone, and I have microphone permissions turned on, so I dont know what to do. Please help!

Welcome to Android Central! Which phone? Does this persist after a reboot?

 

[Haley Westbrook]

I have a samsung galaxy s9+, and yes, I still am unable to select the "google" option under voice input after I restarted my phone

 

[B. Diddy]

Sorry, can you clarify where's the Voice Input menu you referred to?

 

[Haley Westbrook]

Under settings, general management, language and input, on screen keyboard. It says Samsung voice input with a blue microphone icon

 

[Haley Westbrook]

It wont allow me to select options under samsung voice input either. The specific one I was referring to with the google and basic google recognition can be found typing "voice input" into the search bar in settings and selecting the one under "lock screen and security." That will take you to the google/basic google recognition options

I might not be able to help that effectively, since I don't have a Samsung device to test on. Let me see if @SpookDroid can help.

 

[Haley Westbrook]

Okay thank you!

I don't see those options in Lockscreen and Security, but that might be because I don't set up my Google Assistant to respond automatically on my phone (I already have speakers around me that do that, don't need my phone turning on whenever I say those words).

So, let's check the basics. Under Settings, go to Google, scroll down to Search,Assistant & Voice, then tap Google Assistant. There (make sure it's the right account), tap the Assistant tab and under the Assistant Devices section select PHONE. (Phew! Still there?) In there, in the 'Get hands-free help with Voice Match', are the two toggles there active (one to enable the hotword when the screen is on, one to unlock the device with it)?

 

[Haley Westbrook]

The two toggles under "get hands free help with voice match" are greyed out. They wont let me select either of them.

I don't know if anyone found a solution but it's been bugging me all day and I figured out how to fix mine. My notifications for Google were switched off. I have after switching it back on and restarting my phone I was able to turn on the greyed out option.

Hope this helped even if it is a long time ago
