It was already known that the Galaxy S9 would be unveiled during the Mobile World Congress 2018. However, Samsung officially today announced the date of its new top-of-the-line smartphone. Information about it will be revealed by the company on February 25th – and the company’s announcement leads to expect some interesting news regarding the device’s camera.
As previously mentioned, the device must have a 845 Snapdragon processor or Samsung’s own manufacturing equivalent, 4 GB or 6 GB of RAM and storage options starting at 64 GB. It should follow the same trend as the S8 – a normal version and a Plus version, different only in screen size and battery capacity. The company’s announcement through Twitter can be seen below:

However, according to the Android Authority, the Galaxy S9 should differentiate itself from the company’s previous handsets because of a variable aperture technology in the lens of its rear camera. It should come with a 12 MP sensor and should be able to vary its aperture between f / 1.5 and f / 2.4.
The lens aperture is the space through which light reaches the camera sensor. The smaller the number, the more light comes to the sensor. A sensor that receives more light works best in low-light conditions such as outdoor shots taken at night or indoor shots in low-light locations.
On the other hand, to take pictures with the blurred background (such as those that the iPhone 8 Plus and Galaxy Note 8 take in portrait mode), a lens with smaller aperture is more appropriate. It is therefore likely that Samsung intends to use this variable aperture technology to make these images possible without the need to include two cameras on the back of the device.
