Samsung's event invite for the Feb. 25 unveiling event teases that the new devices will include a "reimagined" camera. Leaks and rumors have filled in some of the details: the Galaxy S9+ is expected to feature a dual-camera setup of 12-megapixel cameras, while the Galaxy S9 will stick with a single 12-megapixel camera. Features of the new cameras could include variable aperture capabilities, "tag shot" (which tags photos with the current location) and slow-motion video. The camera system may also enable a new form of biometric authentication that combines both facial and iris scanning, potentially called "Intelligent Scan."
By contrast, both the Galaxy S8 and S8+ feature a single rear camera, of 12 megapixels, without variable aperture capabilities or combined facial and iris scanning.
