Perhaps sticking the camera has become a stumbling block for anyone who wanted to buy a new iPhone. It turned out that bulging optics - it's the worst thing that can happen in a person's life and everyone thought his duty to tell the public that Jonny Ive is not the same, just made this design miss.
However, whether this blunder? The answer to this question was given by Engineer NASA, Robert Frost.
Designers and engineers, who were able to put a number of parts in such a small camera module deserve great respect. Since at this point to make a thinner module with the same recording quality is simply impossible, the only possible solution to the issue protruding camera could only be thicker body smartphone.
Since 87% iPhone users carry the device in the bag, bulging camera will not be a critical issue. Apple could not make the camera slimmer, but I could do body fatter. Value for doing this? Definitely not.
Now, there are more subtle modules, however, the amount of light that they miss less than that of the module 6 and iPhone 6 Plus is, in this regard, resulting photos are noisy. Do not think that you are smarter than engineers. If they were able to insert as much good, but not bulging module, they would have done it.
But since at the moment it can not be done, we will have to settle for sticking the camera. Nevertheless, this "deficiency" probably correct in the next generation of devices.
