Google’s Pixel Visual Core just got an update today through Google Play to v1.0.185741828.
There isn’t a changelog for the update, so we don’t know what Google tweaked here. However, this app (or service) “updates image processing and machine learning algorithms on Pixel 2 phones,” so I’d assume any update means Google has done some tweaking.
Just this month, Google turned on the Pixel Visual Core for all 3rd party apps that want to take advantage of its processing power and HDR+ skills. It could be that this update improves that experience for other camera apps.
The update should be live on your Pixel 2 phone right now.
