It turns out that Samsung Galaxy S7 is not in two variants (edge and flat), but at least a few others. The differences are not visible, because they concern the components. In addition to two different processors they are also (again …) two different matrices camera.
Photographic tests Samsung Galaxy S7 appears on the Spider’s Web soon. Mateusz Nowak already compares images of S7 and iPhone 6s, and soon the camera of the smartphone, check it myself, what I was waiting with undisguised excitement. If the first reviews are confirmed, we will have a new king of mobile photography.
It turns out, however, that various models of the Galaxy S7 will be equipped with different types of matrices
The same situation occurred in the predecessor of the model. Part of dies was transducers from Sony and Samsung’s own part of the production. Both matrices were very good and gave similar results, but the tests clearly showed that there are differences between them, eg. In mapping the white balance.
The Samsung Galaxy S7 is similar. Some of the models uses an array of Sony IMX260, and part of Samsung’s ISOCELL S5K2K1 production. What’s more, it seems that there is no correlation between the country and the distribution of the sensor. Both models of the US (with a Snapdragon 820) and European (with the Exynos 8890) have different types of matrices.
It’s a strange practice that is not entirely fair to the customer. It is as if the manufacturer assumed that the customer is not very intelligent and not notice the difference. Most people do not return the attention to detail which is a matrix, but there are customers who, before buying a smartphone they want to know what they are buying. In particular, the pay is not enough.
Crazy team of enthusiasts with chipworks.com undressed Samsung Galaxy S7 to pieces and checked what lies inside.
In the tested model was new transmitter Sony IMX260 designation. It is a matrix Exmor RS of the third generation, and so it is done in the best technology, which has now Sony. It is a CMOS BSI (back-illuminated side), the layers are stacked (stacked).
is a diagonal matrix 1 / 2.5 inches and a resolution of 12.3 million pixels, each of which has a size of 1 4 microns. One of the biggest news, however, is a new system autofocusu built directly into the matrix. 100% of the pixels on the sensor is both cell detection phase, and therefore outside the collection of light participates in focusing.
It is very important, because the system AF gets more light, so more information on the (in) focus . As a result, the focus is to be set record time, especially when enough light. And that is important, because in such conditions cameras have the most problems with finding focus.

Service Chipworks presented interesting photo of the new matrix. The black surface of the pixels which cell detection phase, and colored pixels around the most likely are inactive and do not participate in the recording of the image. Trivia is more, for example. Stability applied to the lens.
And what is the matrix Samsung ISOCELL?
Samsung on its website boasts that his new matrix uses technology ISOCELL, which isolates photodiodes on a single pixel by a physical barrier between pixels. This makes the data of the adjacent pixels do not interfere with each other, the image quality is higher. We do not know whether the same technology uses a Sony sensor, but in the forum XDA already there are voices that the matrix ISOCELL gives you better quality pictures.
The Galaxy S7 much attention is paid to processors, or to systems Exynos 8890 and Snapdragon 820. I am sure that they will appear performance comparisons and prądożerności these systems. Nobody is hardly surprising. Comparison of image quality with two different matrices for me are equally important.
