Android 8.1 Oreo arriving on Pixel phones "in the coming weeks"
Apparently, the Pixel 2 smartphones feature Google's first custom-designed co-processor, which is called Pixel Visual Core. The processor handles imaging and ML apps, and it's supposed to offer lower-latency and more power-efficient HDR+ processing.
Later on, the component will be enabled for all third-party apps using the Android Camera API, allowing them full access to the Pixel 2's HDR+ technology.
Unfortunately, aside from enabling Pixel Visual Core on the Pixel phones, there's not much else we know about other features Android 8.1 Oreo might bring into the mix.
