The brightness changes too often if left in auto. It obviously needs work. However, I don't really mind, because I think I could easily get used to it. The other thing is that the screen is just so bright that I have been leaving in at low brightness in manual, and that is plenty for me.
If there is already an update available for this, that is amazing. Erike, I'm assuming that it was an app update that you saw, improving the extra settings. HTC has their "Attentive Phone" app that does not show up in the app list, but in the settings. I can only assume that it is the same thing here. I searched the Samsung Zone, and there is no such app that describes what the auto display intensity feature does. Of course, it is likely hidden. I'm hoping they get this resolved soon because there is little excuse for it, and it will likely be getting a bit of press.
