TrippyZ , via OnePlus Nord , Jul 28, 2021 : What is this option for on the selfie cam? I assumed it was 'smile detection' but it doesn't seem to take a photo. Maybe it doesn't like my smile? I do get yellow boxes drawn around faces but that's about it. It also seems to have have a 1-2-3 tiny numerals embedded in the icon, 'detect three smiles'?
