Understand The Mechanism Of The Camera Aperture Samsung Galaxy S9
Samsung Galaxy S9 / S9 + are two new super launches with the ambition to redefine the ability to take pictures on smartphones. Equipped with two f / 1.5 and f / 2.4 apertures, the camera on the Galaxy S9 will meet almost all shooting conditions, even in extremely dark environments or in bright places. JerryRigEverything has posted a close-up video of a Galaxy S9 operation on the youtube channel and tested the aperture on the camera.
After it was quite difficult to open the back as well as the circuit board, battery and related components, JerryRigEverything had access to the camera module. The lens can be moved in 4 dimensions in the module. This is the OIS optical anti-shake system integrated into the camera of the Galaxy S9.

After removing the camera protection, we will see the aperture mechanism of the Galaxy S9. This is a two-position lever, which controls the f / 1.5 to f / 2.4 and vice versa. Because it can be changed by turning the needle, the aperture is an electrically controlled aperture like the one with a DSLR.

Below the lens is a 12 megapixel CMOS image sensor.
To control the aperture system as well as the optical anti-shake, the Galaxy S9 is equipped with electromagnets around the module. These magnets will increase the suction power to be able to “hang” the lens system in balance with the image sensor. Finally, it allows changing the position of the lever, which allows the aperture on the lens to be changed.
