Design and Display

The A21s has an eyeball-grabbing design with a plastic back, and a gradient finish. The backside is kept plain, with no engravings or patterns. The device has a classy look and feels good on the hand. The front side has a 6.5-inch Infinity-O display, with a punch hole towards the left corner, and an LCD panel with HD+ resolution. The device has a rear-facing physical fingerprint reader.


There are four cameras on the Galaxy A21s. Two of them— the depth and macro cameras — are equipped with 2-megapixel sensors. The depth camera is primarily used for background blur in bokeh photos. There is also a macro camera in the device. The primary camera of 48 megapixels gives detailed and superb quality photos. There is, however, no dedicated Night mode, slow motion and hyper-lapse modes. The ultra-wide camera is useful, though it has an average picture quality.
