On a ZenFone 8, Android 12
Occasionally i notice some type of lockscreen when I pull my phone out of my pocket, but it is gone before I get a good look. It says something about using the proximity sensor to detect Bering in a pocket. The screen has a red tint.
I have been unable to trigger the screen, but would like to better understand what the feature is.
I have also seen another screen that said something about "swipe up with two fingers to unlock". That seems very useful, but again I have been unable to find how it is triggered.
Does anyone know how to trigger these screens, or where to find some sort of documentation on the functions.
