Still crap, just saying, so you don't get your hopes up like I did, when I was reading some reviews :smile:
My iris scanner/windows hello works very smoothly both with or without glasses. Was fine even on AU, but is now even faster after CU installed today. Only time it has problems is outside in bright sunlight when I cant keep my eyes fully opened due to intense light. Really like this feature. I trained the scanner when I first started using it in various light conditions with and without glasses and I try looking at the Microsoft text, opens up very fast every time. I also try not to tilt my phone away but hold it in a straight line parallell to my face.
