Chrome Version       : <copy from 
Samsung settings 
Video issue within vision & dexterity accessibility settings  
After accidentally turning on a facial recognition feature in the phone settings.
The screen remained locked whilst a red scanning line repeatedly 'scanned' my face I tapped my home screen icons the scanner boxed in the icon tapped after which a flash notification popped up face not recognised whilst making a low blooper/humming noise.
I'm not sure if this is a debugging issue or not for myself it was very frustrating as I had no idea or was I able to access 
My phone to search via the settings app or access help/advice via the many Google tools! 
I eventually was able to switch off the phone after numerous attempts to which the normal phone function returned.
I would like to know what settings I changed for this to have happened and how to turn this funtion off if it were to be accidentally accessed/applied 
In the future! 
Many Thanks
