Motorola's Touchless Control seen on a few of their most recent Motorola phones, especially the Moto X got another update. This updates most notable feature is the "Find my phone" feature.
Activating your Moto X by using the phrase "Okay, Google Now" will wake your phone and be actively awaiting your command. If you say "Find my phone" it shows the white screen shown above, along with a decently high pitch tone.
If you got yourself a Moto X or newer compatible Android Phone, be sure to grab this update... if you can find your phone.
If you manage to find your phone, you can find this app via the Google Play Store HERE
