I have a Samsung Galaxy S4 running Android 5.0.2 stock, and I'd like to use the facial recognition in addition to drawing an unlock-pattern. This works fine, my face is recognized, but after that, only the dots of the unlock-pattern disappear, meaning I still have to swipe the screen in order to get to the home-screen (where the icons are). I'd like to go to that screen directly when my face is recognized, without the swipe-part. So what's the clue getting rid of that? If I have to swipe, faciol recognition is useless in my opinion, because if I swipe the screen or if I swipe a pattern makes no real difference. So how is this intended to work?
In some of the Samsung devices there is a bug in the stock rom that forces the swipe unlock to prompt even when you have by-passed your lock screen and acts as a double lock screen. This is solved if you switch to a custom ROM instead. In Some cases you want to check the lock screen tab under the settings menu and uncheck something as Use Swipe to unlock. And select the facial recognition under the settings -> Lock screen option.
Hope this helps!!
