The best Camera for HTC 10 no matter Nougat or Oreo is Arnova version 7 test 1 !
Thats it by the best i mean FAST view portrait on both cameras fast HDR+ processing no greenish tint, Improve Sharpness also work, awesome quality from both cameras the only one problem like i say thousend times with all Arnova Builds in dark using flash light crash if there is not close up object to focus if there is an object to focus no problem will take the picture.
so for daily driver this is the best so far. you wont find it anywhere so because was not released officially.
Install this and Thank me later

The problem is this ALL pixel2 based Arnova Builds and all other builds from different developers who use the Arnovapixel 2 mod for a base have the same BUG with crashing in the dark when have to be used flashlight if the object is not close enought its seems like te Pdaf senzor or something related cant focuse the object and this is the reason the camera to crash, for our bad luck there is no developer for HTC 10 so nobody can fix it if someone can this will be most stable build that everything works in all situations.

for Night Shoot and daily driver as well you can use the other that i recoment it is
Tolyan 1.3.2 Version this is super version Portrait doesnt work but it takes amazing night shoot wit Pixel 2017 configs sometimes i use this as a daily driver if i dont need portrait mode.

MGC_5.1.018_v2e_tolyan009_v1.3.2.apk
Oposite to the above all builds thats are 5.1.018 based on BSG doesnt have the flashlight bug and all of them can take night shoots with flashlight without a problem.
Both Cameras work fine under Android 7 and 8 Sense ROMs also with AR Core stickers and so on.
