Samsung Galaxy Z Fold3
This device is Samsung’s most advanced foldable mobile phone to date. With the Galaxy Z Fold3, the South Korean company has demonstrated its capacity when it comes to innovation. This phone is the first foldable smartphone with an under-display camera in addition to being the first foldable smartphone with water resistance.
It comes with a 12MP main camera, a 10MP outdoor selfie camera, and a 4MP under-display front camera.
The main disadvantage of this phone compared to other models is its price. Because it is more expensive than the other models because of the form factor.
- The first foldable with water resistance
- Great specs
- Versatile camera setup
- Too expensive
ZTE Axon 30
ZTE has more experience with under-display cameras when you think of the rest of the brands. This device comes with a new generation under-display camera, with a pixel array designed in a special way to improve the passage of light.
The sensor is hidden behind a huge nearly 7-inch diagonal Full HD display with a 120Hz refresh rate. It is powered by a Qualcomm Snapdragon 870 processor, a 4,200 mAh battery with 65W fast charging support. It has a 64MP main sensor, an 8MP secondary sensor, a 5MP macro sensor and a 2MP portrait sensor.

How do under-display cameras work?
Even though each manufacturer uses its own “approach” when developing these systems, the basics elements are always the same.
In most smartphones with this feature, in the area where the camera is hidden, we will see a small rectangle in certain situations, with less sharpness or a lower brightness level.
This is because the cameras need to have the most transparent material possible in front of them in order to capture the light and generate the image. In the case of smartphones with an under-display camera, a small rectangle using a semi-transparent material needs to be integrated over the camera. This allows the light to pass through the glass to reach the sensor. Each brand will use its own semi-transparent material technology.
In addition, in order for the light to reach the sensor, there must be gaps between the pixels in the area of the screen covered by the sensor. Given the size of these gaps, the pixel density, and therefore the sharpness of that area is reduced to some extent.
