There are plenty of rumors about the upcoming Apple iPhone 6S and 6S Plus that I have heard so far. One of those rumors said the next generation iPhone will feature a 12-megapixel main camera, and it seems the information is confirmed by now, according to the Business Insider report.
Following the report, this new camera is not only just upgrade about the megapixel, but also brings a bigger image sensor into the camera (compared to previous iPhones). By that, the new iPhone 6S and 6S+ will able to take brighter photos.
Also, according to the source, Apple will use the same lens setup for the next generation iPhone, like on previous models with five-element lens. Apple has ordered six-element lens, but it seems the component will be used in the Apple iPhone 7 in 2016.
