LG5 - 13MP normal view angle + 8 MP wide angle lens. Can't use both to combine effect I think. Won't be a meaning comparison.
It would a 12MP+12MP combo vs a single lens 13 MP more likely. Correct me if I am wrong.
fergsu, I think you're right. Because the monochrome does not have to debayer the image, it is going to be slightly higher resolution 13MP seems to be right. But because the RGB sensor color information has to be mapped on this, more probably it's going to be same 12MP for color picture but 13MP for monochrome. I don't know, have to see.
There is a good discussion in the comments section for the otherwise shitty article written here:

Let me repeat some of my comments here:
When you wrote "You're paying for that monochrome sensor in there, the one that you'll probably never use", Mike Lowe, you are wrong. Kindly revise your article. Not only that sentence, but write the whole thing again in the light of new knowledge.
The monochrome sensor has 2 main functions:
1) To take monochrome pictures, and
2) To increase the signal to noise ratio of the RGB color image of the 2nd camera by combining the monochrome picture (superior S:N) as the luminosity channel with the RGB image (color but inferior S:N). It creates what astrophotographers call an LRGB picture.
Also you are confusing f-number. f-number is f/D where f is the focal length and D is the diameter of the aperture. So there are 2 aspects: aperture size concerning depth of field, and amount of light gathered.
Having 2 lenses changes things a little bit so from the perspective of light gathered, the f-number is correctly virtualized. Since it was stated that the Huawei P9's dual Leica lens system takes in 75% more light than the S7's f/1.7 lens, that means 3/4 stop better than f/1.7 hence the virtual f-number of the dual lens system should be about f/1.2. However, this is the part of the f-number which determines `amount of light' and not bokeh.
The f/0.95 number you quoted was NOT relating to the amount of light, but it was the part of the f-number which determines bokeh. In this case it is virtual bokeh - means that the f-number adjustments in the bokeh mode virtualizes only the depth of field, but the light aspect ability of the f-number is determined separately as stated in the preceding paragraph.
As long as you understand what the dual lens system actually does - basically to combine 2 images to improve signal to noise - and separate that ability from the post-shot filtering and trick modes, you will not make such a critical error again.
