Samsung a21 Design and Build quality

Although the Galaxy A21s is a budget phone, it doesn't need to be cheap. The screen takes up most of the front, and the frame and back are made from plastic. Samsung is a master at making phones that look good. We are very pleased with the Galaxy A21s. The bezels are thin and have rounded corners, as with all recent displays.

Although the Galaxy A20 was equipped with a Super AMOLED screen, the manufacturer switched to LCDs for the A20s. Later, this switch was made to the A21 duo. The majority of A series screens come with AMOLED screens, so there are many options. 

You can expect uneven backlighting around cutouts, but this is to be expected with an LCD panel. Samsung has minimized this unevenness, which is a significant improvement on the other more expensive options.

Inside this cutout is a small 13MP self-portrait camera. The protective glass meets the screen at the top, and the earpiece grille can be found above the screen. If you are curious, there is no LED notification light on the A21s.

The frame is made of solid plastic and is curved. The matte finish gives it a more gripping feel, particularly when shooting photos or watching movies on the go.

The frame houses all the essentials: the volume and power keys are on the left and the triple-card slot on the right. While the bottom contains the USB-C port and speaker, as well as the 3.5mm audio jack and the mouthpiece.

The rear panel is also made from plastic. However, it now has several layers of paint and is glossy. It looks great if it isn't covered in fingerprints or smudges. A subtle blue/purple-green gradient depends on the surrounding reflected light. The back of your piece will need to be cleaned regularly if you want it to look great.

The quad-camera setup is on the back A21s. A black rectangle separates them. It protrudes only a little and will not cause the phone to wobble on your desk.
