Google has done what they said they would. You can now trigger voice search anywhere on your Android smartphone with a new Google Search update. This new feature is similar to what you can do with a Moto X but now it is available for all Android phones. Just say “Ok Google” when your screen is on and tell Google Now what to do. You can even activate the feature from the lock screen.
Just head to Google Now and select the menu at the bottom right of the phone and then tap on Settings, then Voice, and then select “Ok Google” Detection. According to Gizmodo, this feature is rolling out phone by phone. We’ve tested it on the Nexus 5 and it seems to be working already. Just be a bit patient if it hasn’t landed on your Android just yet.
