It's pitty nobody posts lately photos from this nexus phone(s)
I have seen portrait samples from all top smartphones, and one thing is for sure. Nexus 5X / 6P with HDR+ are by far the best for portraits of any kind, (pets, children, adults). It is closest to natural. All the other flagships (S7, G5, HTC 10 etc) add NR in photos and it remove face's details, but not nexus phones. If only these phones had features like eg. my phone G4. (SD card, radio, IR blaster, removable battery)... It would be by far best seller phones...
