why can't we use both facial & retina recognition

[tomcat777]

It would be great if we could use both the facial recognition and the Iris scanner....or better yet have the Iris scanner come on automatically when low light is recognized by the phone. Surely Samsung or even a third party developer can come up with something like this. I love facial recognition, but would love to have it switch in low light. Any thoughts on this?

Why not use more secure iris instead of face.
I wear glasses and surprised how well iris works including at night though I haven't used in very bright sunlight

Same for me. The Iris scanner works great through my glasses even in the dark.

Doesn't work when I'm squinting upon wake up but of course. How does iris work in full sunny day??

I find iris scanner works better in lower light conditions.
I use fingerprint scan most of the time but iris scan too, both very good.

I live near Seattle. This isn't the time of year for bright sunny days.

Many times can't work under bright sunlight for me

We can't use both because Samsung sucks

Iris scan works great for me, in the sun, with sun glasses on, dark even in the morning when I'm squinty just not one eye open both need to be open for it to work but other than no problems at all and I don't find one eye a problem I like that I know its working when it won't work for one eye lol
