Gave the cameras on Nexus 5X and iPhone 6 a try. Let the phones do the thinking, raise the phones and take the shots. The HDR was off and no post processing.
Nexus got better color but iPhone got the sky.
Photo from the iPhone looks nice and warm.
This time photo from Nexus looks warmer. It has wider background to measure the light?
A couple steps closer ... iPhone photo is warmer. The difference is not much but noticeable.
I like the color produced by the iPhone’s camera. But overall, both cameras are good.
