I just upgraded my phone to the new Android version 4.04 and I am missing the "face unlock" feature on the security menu. Does anyone know what is going on? Its weird. I thought I had it earlier when I first did the upgrade by my phone ringers were not working right. So I just took out the battery and powered up again. Everything seemed to be working fine and now the "face unlock" feature is missing from the phone. any ideas/suggestions? thanks in advance!
