The app with this feature is not yet available on Google Play.
The feature appeared in the Android Accessibility Suite 12.0.0 application, released together with the fourth beta version of Android 12. An updated version of the application with this feature is not yet available on Google Play, writes the website of mobile developers XDA.
There are six gestures in the application: open mouth, smile, raised eyebrows, look to the left, look to the right, look up. You can assign a specific action to each of them — for example, open the application, go to settings, scroll through and others.
The user can adjust the sensitivity level of the software when recognizing facial expressions to limit the possibility of accidental actions. The application also warns that the function may be energy-consuming, and it is better to connect the phone to the network during use.
According to The Verge, the function can be useful for those who have difficulties with touch control. Unlike voice commands, facial expressions can simplify the use of smartphones in public places or in a quieter environment, the publication writes and notes that the update may become available before the end of 2021.
