Scene Optimizer isn't the only Galaxy Note 9 feature making its way over to the Galaxy S9 and Galaxy S9+. In addition, it looks like the Galaxy S9's Android Pie update will bring the Galaxy Note 9's Flaw Detection feature.
If you're unfamiliar, the Galaxy Note 9's Flaw Detection feature analyzes your photos and detects flaws like blurriness, blinking, and smudges in your photos.
It's a nifty feature (it's not gimmicky like some of Samsung's other software features) and one that we've been enjoying on the Galaxy Note 9 so far.
