If FaceID needs 25-50cm of difference to work properly and even in a perfect scenario, it's still slightly slower than gen 2 TouchID, seems it's somewhat of a step backwards. They should have kept the fps on the back and swallowed their pride. This is s perfect scenario and the one on the right seems slightly annoying to me. There is also no telling how it would work with odd angles and glasses. It's why I didn't buy the Note 8. The iris scanner needs angles and is hit or miss with glasses. I guess I will find out when I receive mine in a month
Correct, but on a Note 8 I can put my finger on the FPS at the same time I look at the phone. Its a race. One of them will win and it is different each time. If my phone is coming out of my pocket, then the FPS will always win. If its on the charger on my desk then Iris will win.
For all that bought the X, I hope it works well or that is a lot of money to spend and have it not. If they nail it then it is good for everyone because the better tech will proliferate. I just didn't want to take the risk.
