Pixel’s Visual Core for third party apps tested: Here’s what we found


The camera on Google Pixel 2 works with a key ingredient called the Visual Core, which makes it as good as it is.

We tested the Pixel phones with and without the Visual Core chipset.

We compared samples from Pixel 2 XL running Visual Core update against the one without it, and found out something really interesting.

In the picture above, Instagram camera has tried to balance the exposure but the image looks washed out when compared to the …read more
