as reported by Android Police, but before long, no one will be able to fully unlock an Android device using just their voice anymore. Instead of that, "Access with Voice Match" can be enabled to read or show personal results from your email, calendar, contacts, reminders, memory aids, and shopping lists.Curiously enough, it took many months for this security-improving feature to start spreading to other phones,
Basically, saying "Ok Google" in the presence of your phone will technically keep it locked while still allowing you to perform a few hands-free tasks. Everything else now requires a different, more secure form of unlocking, like scanning your fingerprint or entering a password. As Google explains in a support document, a "similar voice or recording of your own voice" could be used to unlawfully unlock your device with previous Voice Match settings, which is why these new restrictions were needed.
To enable voice-commanded lock screen personal results, all you have to do is access your Google Assistant settings by tapping the little compass icon on your phone's bottom right corner after touching and holding the home button, selecting your device, and turning on both "Access with Voice Match" and "Lock screen personal results." While significantly less convenient than before, the feature should be safer to use, which sounds like a pretty decent compromise.
