The World's First Smartphone with Four Cameras

The world's first smartphone with four cameras is not, contrary to expectations, a flagship device but a mid-range phone: the "Samsung Galaxy A9." The Samsung Galaxy "A9" features four cameras on the back with different sensors and lenses for various purposes. The main sensor has a resolution of 24 megapixels and uses a lens with an aperture of 1.7 and autofocus capability. The second camera has a 10-megapixel sensor with a lens that has an aperture of 2.4, autofocus, and 2x optical zoom. The third camera uses an 8-megapixel sensor with a 120-degree wide-angle view and an aperture of 2.4, while the fourth camera, which is used for depth detection, has a 5-megapixel sensor with a lens of 2.2. However, how is this high number of cameras utilized, especially when the Google Pixel 3 achieves all these functionalities with just one camera? Essentially, if the hardware of this phone were strong and its software could effectively utilize artificial intelligence, there would be no need for so many cameras. Samsung has compensated for the weak hardware of a mid-range phone by adding more cameras for photography. Additionally, this high number of cameras on the back of the phone could serve as a better marketing tactic to attract more customers for this South Korean company. The software of this phone's camera is quite similar to that of the Galaxy Note 9 and employs artificial intelligence to detect subjects and adjust photography parameters accordingly. For selfies, this product is equipped with a 24-megapixel camera with a lens of 2.0. Among these four cameras, having a depth-sensing camera may seem excessive. This camera does not take any photos and only detects the subject in portrait mode, separating it from the background. Some phones, like the Google Pixels, can perform this feature with just one camera, but due to the low processing power of this mobile phone, Samsung has resorted to such a trick. This phone features a 6.3-inch display with a resolution of 2220 × 1080 pixels. For the processor, this phone uses an eight-core Snapdragon 660, which is weaker than even the cheapest iPhones. Even the latest series of iPhone SE has stronger processors than this phone. However, the RAM of this phone is between six to eight gigabytes, which is more than all iPhones. Currently, the strongest iPhones only have four gigabytes of RAM. This phone has 128 gigabytes of internal memory and can support a microSD card of up to 512 gigabytes. The battery of this phone is 3800 mAh, indicating that Samsung remains cautious in increasing battery capacity due to fears of its phones catching fire. The Galaxy "A9" will be launched in its base model at a price of 599 euros in mid-November (late Aban) in three colors: blue, black, and pink in Europe; a price that seems high for a mid-range phone. With this price, one could purchase some flagship Android phones that use the more powerful Snapdragon 845 processor. Meanwhile, the processor of this phone is of the Snapdragon 660 type, which is not very strong and will likely perform slowly in applications that require more data processing.
