Editor in Chief of XDA-Developers Mishaal Rahman managed to get a hidden feature of Google Home devices to work and posted the screenshots to Twitter. Google and Nest Home devices that listen for the wake phrase: Hey Google will be given a new slider adjustment for tuning the sensitivity of the phrase.

I can personally say that my Google Home Mini has trouble hearing me in the kitchen, perhaps due to the broad acoustics in its location, so I cant wait tweak it to be able to hear me utter the wake phrase and not have to keep saying Hey Google until I see the LEDs light up.
Conversely, if your Google Home speaker is constantly firing off queries you didnt ask it, lowering this sensitivity should make it so you dont have as many false activations.
As per Rahmans Twitter thread, the new feature will work for both Google and Nest Home speakers and smart displays. We are still wondering if the option will only be added to Google and Nest-branded Home devices, or if other third-party Google Assistant-enabled devices will see the same setting as well.
Following the initial posting of the screenshots, Google confirmed to The Verge that the feature has indeed begun rolling out, but gradually.
