Samsung Galaxy M21 Review

Score: 84.1 / 100

Samsung Galaxy M21 is a very high-end Android device released back in the year 2020, provisioned with a really big 6.4 inches display, an extremely fast 2.3 GHz Octa-Core processing unit, a 48 MP back camera and a 20 megapixels front camera. But it's time to get into a bit more details.

This cellphone ships with a Exynos 9611 chip, backed up by a great Octa-Core CPU running at 2.3 gigahertz and a big 4 GB RAM memory. A great point of this phone is its 64 GB large internal storage and a slot for an external memory card, enough to store tons of applications, games, photos and videos without having to worry about how much memory is left.

This cellphone is available in two different colors, midnight blue and raven black. This phone construction is a mix of Plastic and Plastic . The M21 is a bit heavy for a phone this size, with a weight of 6.63 oz. The Samsung Galaxy M21 is a compact cellphone, taking into consideration it presents a 6.4 inches display and it's only 6.26" long and 2.96" wide. The M21 is extremely slim, being just 0.35 inches thick.

The M21 is equipped with two cameras, a 48 megapixels back-facing camera and a 20 megapixels front side camera. Its back-facing camera has a f/2 aperture so it can shoot great pictures even in low light environments. This cellphone can also capture videos up to 3840x2160 (4K) at 30 fps, and Full HD 1920x1080 slow motion videos up to 240 fps (8 times slower than regular videos).

Samsung equipped this cellphone with a gorgeous 6.4" display, and a resolution of 1080 x 2340 , which makes everything look absolutely great.

This cellphone offers WiFi capability (which it can share with other devices around, as a mobile hotspot), LTE-A 4G high speed connection type and also HSPA+ data connection (which is a lower speed 4G type) and 3G fast connection type, using HSDPA and HSUPA technologies. This phone has dual SIM cards so it's able to work with two different carriers or phone numbers.

This cellphone also features lots of cool features such as Biometric fingerprint, Facial recognition to unlock, Bluetooth, GPS (Global Positioning System) and FM Radio, and a couple sensors likeProximity Sensor, Accelerometer and Gyroscope.

This cellphone features an awesome 6000 mAh Li - Polymer non-removable battery that can keep it running for many hours and even reach the end of the day without charging it at all. An issue to evaluate is that this cellphone's battery is non-removable so you won't be able to replace it when it begins to last shorter, even though with such a great capacity you will probably discard this cellphone before that happens.

This cellphone is probably a good choice for you if you want it for gaming, want a social phone, want it to take plenty of pictures or are looking for a cellphone for work.
