According to the latest reports form Chinese forum Weibo, Samsung has been suitably impressed with the 23MP IMX300 camera sensor found in the Sony Xperia Z5. So much so, in fact, that it wants to shove it into the Galaxy S7.
While Sony currently has exclusive rights to that particular sensor, it’ll be very tempting for it to strike a deal with Samsung, given the number of Galaxy flagships the company shifts.
Samsung is also working on its own 20MP ISOCELL sensor too, which, according to rumours, uses a newer RGB colour pattern to improve low light performance.
It’s likely that Samsung, as it has done with processor variants in the past, will use Sony’s sensor in selected markets, while sticking to its own offering in others, but we'll just have to wait and see.
