Exclusive: Galaxy S21 features to include Bixby Voice as a biometric option - SamMobile

There will naturally be a couple of new features that will be exclusive to the Galaxy S21 until One UI 3.1 is released for other Galaxy devices, and according to our sources, one of those features will be the option to use Bixby Voice as a biometric method for unlocking the device.

Bixby itself has had the ability to unlock the device to follow your commands when you wake it up by saying ‘Hi Bixby’, and initially, it also offered the option to set a voice password for hands-free device unlocking.

Neither of those features can be found in Bixby anymore, but we’re told One UI 3.1 will let you select Bixby voice unlock from the phone’s lock screen security settings, though the exact details of how it will work are unclear at this time.
