Samsung Galaxy S6 is one of the best Android smartphone and received universal acclaim for its 16 MP camera. It turns out, however, that not every handset has the exact same camera: some phones use a Sony IMX240 imaging sensor while others are equipped with Samsung’s own ISOCELL sensor.
A XDA-Developers user first reported this and Samsung has confirmed the same. According to Samsung spokesperson, there are different vendors who make cameras for Galaxy S6. Although he did not reveal how Samsung distributes those components, it seems it is done in an effort to pad out inadequate supply of whichever sensor is Samsung’s first choice, and is not determined by whether you buy an S6 or Edge variant of the phone.
The Galaxy S6 and S6 Edge utilize camera sensors from several different vendors. Like all of the technology used in our products, they meet our strict global quality and performance standards.
SamMobile has conducted tests showing that the practical differences are slight. Image quality in the sample images appears to be a tie between the two sensors, with Samsung’s ISOCELL showing a slight advantage with a better white balance than the Sony chip.
