Hey Google not working

[Avinesh]

HI. My Hey google does not work for a few months now. Very frustrating as it worked well on my S21 ultra.

I  have tried some recommendations on your forums but have had no success fixing it.

Hi, and welcome to the community,

As this is a 3rd party app then consider reaching out to the Google help forums

However, in the meantime head to Settings >Google>settings for Google Apps. Check for all settings associated with Google Assistant.

FYI. Google Assistant was moved after the recent UI6.1 update. It is now accessible by swiping up from corner of screen. You don't say what UI you are running, which would help here.
