Wow! So you guys sound like there is a disaster in the making.... All to get clicks, of course, like mine.
I have the 6+. It replaced a S5 and an Xperia. It's a MUCH BETTER CAMERA.
The GS5 has a very noticeable dynamic range issue: light areas in the image are blasted out, dark are underexposed. Very noticeable and much more significant than the WB shift you are jumping up and down about.
I am glad that Apple is "investigating the issue" based on your observations and I am sure it makes you feel incredibly important.
But the fact is, the iPhone 6+ camera is still the best camera I've seen on a phone and your article is..., just for clicks (mostly, OK).
