Samsung Galaxy A21 Review

Score: 76.1 / 100

Samsung Galaxy A21 is a great quality Android phone launched some years ago, coming with a large 6.5-inches screen, an extremely powerful Octa-Core processing unit running at 2.3 GHz, and two cameras, a 16 megapixels back camera and a 13 megapixels front camera.

Samsung decided to build this cellphone with a Mediatek Helio P35 system chip, including an extremely fast 2300 megahertz Octa-Core CPU and a huge 3 GB of RAM memory. A great advantage of the Samsung Galaxy A21 is its huge 32 GB internal storage and an external memory slot, which allows the user to install lots of applications, games, pictures and videos without having to worry about running out of space.

Samsung is offering the A21 in color black. Samsung did an amazing design job making this device as lightweight as 6.81 oz. This cellphone is a mix of Plastic and Plastic . Being just 0.32" thick,this phone is very thin and good-looking. This cellphone is just 6.61" long, but it manages to hold a 6.5" display.

This device includes a nice 6.5" display with a 720 x 1600 resolution, which makes it hard to see the pixels composing the display.

This phone counts with WiFi connectivity (which it can share with other devices as a mobile hotspot), LTE-A 4G high bandwidth internet connection and also HSPA+ connectivity (which is a bit slower 4G technology) and the fastest 3G connection type, supported by HSDPA and HSUPA technologies. This phone works with a Nano SIM card to use GSM services.

This phone is equipped with two cameras, a 16 mega-pixels back facing camera and a 13 megapixels front side camera. Even though it's 16 MP may sound great the back facing camera sensor size is quite small which makes photographs be less detailed and darker than they should. It also shoots videos up to 1920x1080 (Full HD) at 30 frames per second.

This cellphone counts with a 4000 mAh big capacity Li - Polymer non-replaceable battery, enough to provide this cellphone with an impressive battery life. An issue to evaluate is that this phone's battery isn't removable so you won't be able to replace it when it begins to get older, though with its 4000 mAh you will probably buy a new device before it becomes a real problem.

The A21 also includes a lot of useful features like Fingerprint Sensor, NFC (to trigger actions, transfer data or make payments by holding your device close to another NFC device or tag), Bluetooth (5.0 ), GPS Geolocation and Radio, and plenty of sensors like Light Sensor, Proximity Sensor, Accelerometer, Gyroscope and Compass.

The A21 is priced about $ 194, which is similar to other similar cellphones. If you are looking for a social cellphone, want a work cellphone, want this phone to take many photos or want a device for playing games, you will probably be very happy with it.
