Recently I found my Google home becomes a bit silly. It never responds to my
Hey Google command any more like before. However
Okay Google still works. Also while playing my Google music playlists, it randomly stops and drops songs which is quite annoying.
Then I notice in the version, its language value is
Japanese which I set previously when there is not dual language support. It turns out this is the reason: I set my Google Home default language to Japanese. Some time later, google release the dual language support and I added English as the second language. However maybe there is bug on this release that now it only support
Okay Google(maybe it is like this in Japanese lang).
To fix this, I need to remove
Japanese first so now
English becomes the default language, then reboot Google home so that the language version reverts to English. Then I can add Japanese back as my second lang. Now finally,
Hey Google works again. Hooray!
