There are several ways to activate Android's mobile phone "Google Assistant", but perhaps the most convenient way seems to be in the way by users around the world now.
More frustrating is that problems are reported on many devices of many companies such as Samsung, LG, Huawei, OnePlus, Xiaomi etc. Google is aware of this problem and studies its root cause, but I do not know when the solution can be expected and I can not find any workarounds for Reddit, Twitter, or a huge support page.
This problem can be explained easily enough to disable "Ok Google" activation. In other words, many people just wake up to Google Assistant, not to wake up, you can not hold the main button of the mobile phone like a savage person.
It is not a serious bug for the security of Android phones and the general user experience, but many people seem to express frustration with social media and enthusiasts using Google Assistant's audio trigger. We are waiting for a solution.
