‘Ok Google’ will not unlock your Android phones anymore
But you can still use it to activate Google Assistant
Bhubaneswar: Google has come up with a compromise to make its “OK Google” feature more secure. Now the feature shall open a Google Assistant interface on locked screen and not unlock our Android phones anymore very soon. The interactions will be limited to “personal results,” things like Google Calendar, email, reminders and shopping lists.
The search-engine giant has decided to limit the “Voice Match” unlock feature to only launch the Assistant interface on the lock screen instead of unlocking the Android device on the basis of voice match.
The idea behind deprecating the “Unlock with Voice Match” feature is probably to enhance security. When you enabled the feature previously, a pop-up message warns that it’s not a secure feature — a similar voice or recording of your voice could unlock the device.
“Moto Z” and “Pixel XL” devices had already lost the functionality with the Google app’s 9.27 update.
With the 9.31 update, other devices that still had continued to have full voice unlocking powers will also lose it.
