CAMERA

Samsung s9 camera got 12 megapixel camera while the s9+ is integrated with dual 12 megapixel cameras.The major change in this Samsung s9 series is the camera,and this is the worlds first phone to have that feature.and that feature is the ability to change the aperture of the camera.

this is a huge step for the Samsung company as this feature is really great to have photos in low light conditions. the aperture can be changed between 1.5-2.4  and that allows the camera to take the photos at the low light conditions.If you take a closer look you can see the camera eye is closing when capturing a photo.and it is the same process like the "human eye"

and when it comes to the video mode this device is compatible with recording 960 frames per second in 720p  and that is ultra slow motion which is a rare video effect on the phone world.so these features have empowered the Samsung s9+.
