ΜMany people may not know it, but it has been possible to unlock your Android device with your voice for several years. However, users either ignore this option, or choose the more "traditional" ways with a pin or pattern or fingerprint or face recognition.
Google, however, seems determined to permanently eliminate the general voice unlock method from the Android operating system and has already made the start of Pixel 3 and Pixel 3 XL. The reason; The fact that it is not so safe, because a similar voice or a recorded message with the user's voice could easily unlock his device.
So, with the first application in Pixel 3 and Pixel 3 XL, Google replaced "Voice Match" with the "Lock Screen Personal Results" function, to show the user only email, calendar and contacts via Google Assistant, but for any other action requires a password or unlock with a fingerprint.
The rest of the Android devices will see the new option by upgrading the Google app to version 8.39
