How To: Enable "OK Google" on all screens of your Android
Want to enable Google Now
voice search from any screen of your Android? Of course you do. Thanks to a recent update to the search app you can now say, “OK Google” from anywhere you want on your Android smartphone or tablet. It’s quite easy to do, actually, and here’s how you go about it in five easy steps.</p>
. Open Google Search
Tap on Voice
Tap on “OK Google” Detection
Check the box for “From any screen”
You’ll have to train the voice model, which really amounts to you saying “OK Google” three times. After that, you’re good to go! Now, which commands
are you going to use?
A couple of things worth noting: This works whenever the screen is on or the device is charging. In other words, you can’t wake it up with the command. Also, if you’d like, you can add the feature to your lock screen, too. Just look for the other check box below “From any screen”.
NOTE: For most Google Now-related tips, you need to be using Android 4.1 or later.
