I have been using the face recognition to unlock my phone since getting it 2 days ago and it worked extremely well making it one of my favorite new features of my S8 plus. But ever since installing the update last night, face recognition has all but stopped working. Despite recapturing the face data multiple times and restarting the phone, I have only been able to get it to work a hand full of times. I am forced to put in pin almost all of the time now. Is anyone else experiencing this? I'm about ready to go into the Verizon store and ask for a new phone.
