The nexus 6P is supposed to be good for low light. Not sure if it really is though... Also the OnePlus X has a pretty good camera but you'll have to put up with their dumb invite system.

And the HTC Desire eye has a great camera, almost as good as the V10s. Neither the V10 or HTC are good in low light though: the LG’s led is too harsh and the HTC is just… Too dark 😛
