A Complete Analysis of the Samsung Galaxy A21 Smartphone

Modern and Beautiful Design of the Galaxy A21

The Samsung Galaxy A21 comes with a matte plastic body, available in black, though more colors are expected to be released in the future. The design of this smartphone is very attractive, with a nice look on both the back and front panels. The selfie camera is located in the top-left corner of the screen, occupying a minimal portion of the display. On the plastic back panel, we find a quad-camera setup with an LED flash placed vertically in the top-left corner. Just below the cameras, there is the fingerprint sensor. On the right edge of the frame, you can see the power button and volume controls, and the frame itself is resistant to fingerprints and smudges. One major issue with many phones in the A-series has been the placement of the speaker at the bottom-left rear of the device. This often led to the hand covering the speaker, causing muffled sound. Samsung has repositioned the speaker in this model, now providing better sound quality. The USB Type-C port is located at the bottom of the device. Another change in this model compared to previous ones is the addition of the fingerprint sensor in the middle of the back panel, designed so that your finger doesn’t accidentally touch the camera, and over time, using this sensor becomes easier.

Display of the Galaxy A21

According to Samsung, the Galaxy A21 features a Super AMOLED display with good brightness and contrast, and it provides readable colors in sunlight. The 6.5-inch screen has a resolution of 720x1600 pixels and an aspect ratio of 20:9, meaning the length of the display is more than twice its width. The pixel density is 270 pixels per inch, which is a good number for an affordable phone. The phone has an Infinity-O display, which refers to the hole-punch design for the selfie camera, so the display remains uninterrupted. The phone also features an Always On Display feature.

The main camera has a 76-degree field of view, while the second camera covers up to 123 degrees, almost matching the human eye’s field of view. The third and fourth cameras are a 2-megapixel macro sensor and a 2-megapixel depth sensor. This quad-camera setup, with autofocus, comes with an LED flash to adjust the lighting according to the environment for better quality images. The camera also supports panorama and HDR modes and can record Full HD videos at 30fps. The selfie camera boasts a 13-megapixel resolution.
