With respect I think you are missing the point of the discussion here.
The phone camera functions, just not as well as the previous model. The issue looks to be software related. I have compared 3x iPhone 6's in our office and they all exhibit the same traits. If this is not a wide spread problem I can only assume that others are less quality critical. (Or we have been unlucky with a dodgy batch!) As a photographer, this looks to me like high compression coupled with aggressive noise reduction in post. Don't get me wrong, if this was the first iPhone I'd purchased I'd be happier not having had a frame of reference. (the 4s & 5s Models).
I'd like to argue that this is 'phone' first, and camera second, but... I do use this camera quite a bit for reference shots etc. It's useable, but sadly the results are not as clean as the previous model. I'm sure an update will improve the overall quality of the final image. As @Tahpagh suggests, a google search reveals that we are not alone. Fingers crossed and all that.
Oh, and the Apple store for a fix... Hmm remember the iPhone 4 antenna issue? Guess we did get a free rubber case to solve that one
