“Hey Google” not working for you? Here’s how to fix it

Back when Google Assistant was launched for smartphones, although it was superb news, users were disappointed for two reasons. First, you could not set a custom command to launch Google Assistant and secondly, you could use only one command ‘Ok Google’, which seemed awkward to say.

Finally, after a long wait, we have some good news to share. Although you still cannot set a custom launch command, Google Assistant users on Android phones can now use the ‘Hey Google’ command to launch Google Assistant. Yes, the ‘Hey Google’ hotword now works on phones that support Google Assistant. This was earlier available to Google Home devices only.

  1. There are four suggestions above of how to get Hey Google to work:
    1) Does not work
    2) Does not work
    3) Does not work
    4) Does Not Work
    5) Here is the only way it will actually work. Have Google release things when they work and not in Beta so it can be tested for free.

  2. This.bullshit still doesn’t work what the fuck is actually wrong?

  3. Samsung S10+ running Android 12 and Google voice not working. Raised a call thru the app to Google. Advice received from them was the equivalent of technical sloping shoulder – try the same approach as above (which, as others have commented, fails to work) and if it doesn’t then contact your supplier.
    I have a very similar ‘Hey Google’ problem on a Maze Alpha, so it’s not Samsung – it’s Google.
    As they cannot get their product to work and they have now kicked Android Auto off the mobile phone platform for Navigation, I’m Wazing them goodbye…

  4. Google are bending us over. This shit they serve to us is obviously untested because it is so unreliable.
    The technology has been developed, Google just do not use the best iteration of it.
    There is a possibility they would have to spend money buying or developing some system that works.
    This could mean shareholders get a slightly smaller dividend than they would prefer.
