Samsung has hinted that the Galaxy S9 might include more advanced face recognition, but we're now getting clues as to what's involved. SamCentral's sleuthing in the settings APK for the Galaxy Note 8's Oreo beta has discovered a hidden Intelligent Scan feature that uses both camera-based face detection and the iris scanner in tandem for "better accuracy and security" and improved results in "low or very bright" lighting. Given that the iris scanning on the S8 and Note 8 can be finnicky, this could deliver a much more consistent experience when you're unlocking your phone or accessing secure info. Just how it works isn't immediately apparent. A video included with the feature suggests that both the iris scanner and camera are active at the same time regardless of the conditions, but it's not certain whether this means combining their data or using one as a backup for the other.
