Face detection in Galaxy note 9

Face detection works pretty fast and seamless
I myself use Intelligent Scan for lock screen security on my Note 9 - it's fast and works 99% except some rare occassions when I am lying on my bed and the phone needs to be kept in the right angle to my face. Seriously, a reliable and safer option than typing PIN, password or PATTERN in public when somebody could be staring over your shoulder or follow your finger movements while typing. Go for it 👍 and let me know if works
