At second preview for Android 11 developers included the option for facial unlocking "requires the eyes to be open", but it was not known for sure if it would be included in the April update for the Pixel 4.
It is finally like that, and, apart from having April security updateYou also have this option to be able to activate or deactivate this option for the face unlock of the Google phone.
If it is interesting to have this option, it is because we are facing a Pixel 4 and Pixel 4 XL that arrived last year with the system of Google's most advanced face unlock. In other words, it has all that advanced technology that one could wish for in this type of unlocking, although the big G forgot a small detail, the requirement by the user that their eyes be open for facial unlocking.
Google has taken 6 months to implement this option, one that is required as far as security is concerned. It is now available on the Pixel 4 with the April update and you can find it from Settings> Security> Face Unlock and the option "Requires eyes to be open" is in the "Requirements for facial unlocking" section.
Surely you will find this option already active by default when you update your brand new Pixel 4. A small detail more than important to be able to complete that advanced technology that Google has with your phone for facial unlocking.
When we have been knowing all of the new Pixel 4a, users who have the 4 already have another function more to be able to use this form of unlocking than for those who are used to it, you can hardly live without it; just like the fingerprint one and it also works like a charm with the right technology.
