Re-Assign the long-press of your device home button
 
Getting Google flags from accidental long-presses. For those who leave the Google Voice assistant unblocked on Android in order to use voice recognition for composing text messages, etc, we can highly recommend installing HomeBot (https://play.google.com/store/apps/details?id=com.abast.homebot) which allows you to assign the long-press on your device home button to something else, such as starting an app or turning on the flashlight, instead of starting the Google Assistant.
