Unlock device using facial recognition and go to Homescreen
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!!
