Samsung Galaxy M21 Design And Display

Samsung Galaxy M21

As far as Aesthetic go, this device looks simple and clean. It didn’t add or remove anything from the design when compared to its predecessor. Most of the upgrades and improvements are on the inside but still on the outside, there is more to talk about.

The display here which stands at 6.4-inch tall is made of Super AMOLED so bright colours and deep blacks are to be expected. The display has a FHD+ (1080p) resolution, uses a 19:9 aspect ratio (with a waterdrop notch) and has 403 pixels per inch density.

A slab of Corning gorilla glass 3 is slapped on top of the display from protection and according to Samsung, the display can reach of 420nits at max brightness. Being a budget device, the back and frame of this device are made of plastic.

The plastic back is also home to the optical fingerprint sensor and the triple rear cameras with flash. Overall, this device weighs 188grams and measures 8.9mm in thickness with two colour options to choose from; Midnight Blue and Raven Black.

Camera Specs

There are a total of three cameras at the rear of this device which consists of a 48MP main camera with an f/2.0 aperture and PDAF, an 8MP ultrawide camera with an f/2.2 aperture and a 5MP depth sensor with an f/2.2 aperture. Features of the rear camera include an LED flash, Panorama and HDR.

The rear camera can also shoot 2160p and 1080p videos at 30fps with gyro-EIS. Meanwhile, the single front-facing 20MP camera in the notch at the top of the display has an f/2.0 aperture, HDR and only shoot 1080p videos at 30fpd.

Hardware and Software

Samsung fitted the Samsung Galaxy M21 with their in-house SoC; Exynos 9611. This Chipset which is based on the 10nm node has an octa-core processor clocking speeds of up 2.3GHz with a Mali-G72 MP3 GPU for graphics.

Battery and Connectivity

Samsung Galaxy M21 has a massive 6,000mAh battery which comes with a 15W fast battery charging technology. Although this is pretty slow by today’s standards, it isn’t bad and is definitely better than no having any at all.

Moving on, it also has 4G LTE, Bluetooth, dual-band WiFi, WiFi hotspot, WiFi direct, GPS, FM radio and a USB Type-C port for charging and file transfer through cable. There is also a 3.5mm jack here which is someone we rarely see on smartphones these days.
