Samsung Galaxy A31 Review

Score: 81.3 / 100

Samsung Galaxy A31 is a very powerful Android cellphone launched in 2020, including a big size 6.4 inches screen, a high-tech Octa-Core CPU ticking at 2000 megahertz, and two cameras, a 48 MP back camera and a 20 megapixels front camera.

Apparently Samsung forgot about optimizing the weight in this 6.53 oz cellphone. Whereas this cellphone only has 6.27" long and 2.88" wide, it still manages to contain a 6.4 inches screen. The A31 is just 0.34 inches thick, making its way into the thinnest phones podium. This phone is for sale in multiple color options like prism crush black, prism crush blue, prism crush red and prism crush white. Talking about its body materials, this cellphone is manufactured with Plastic .

This phone is powered by a MediaTek Helio P65 MT6768 chip, which holds a high performance 2 GHz Octa-Core CPU with a big 4 GB RAM. An excellent feature of the Samsung Galaxy A31 is its huge 64 GB internal memory and a slot for SD memory cards, which allows you to store tons of applications, games, pictures and videos without even thinking about how much memory is left.

Samsung equipped the A31 with an astonishing 6.4-inches screen, and a 1080 x 2400 resolution, which makes all images and videos look perfect.

This cellphone features two cameras, a 48 mega-pixels back camera and a 20 mega-pixels front facing camera. this device's back camera has an aperture of f/2 so it can take clear photos even in poorly lit environments. It is capable of shooting videos in Full HD 1920x1080 at 30 frames per second.

This device features Wi-Fi capability (which it can share with other devices around, acting as a mobile hotspot), 4G LTE-A really quick data connection and also HSPA+ data connection (which is a bit slower 4G variation) and fast 3G data connection, over HSDPA and HSUPA technologies. This cellphone comes with two Nano SIM cards to be able to to use 2 different phone lines or carriers in the same cellphone.

The A31 also features a wide variety of cool features such as Fingerprint unlock, NFC (Near Field Communication), Bluetooth (enables communication with other bluetooth devices, computers, and accessories) and GPS Geolocation, and lots of sensors like Light Sensor, Proximity Sensor, Accelerometer, Gyroscope and Compass.

The A31 uses a 5000 mAh big capacity Li - Polymer non-replaceable battery that provides this cellphone an incredibly long battery life. An issue to take into consideration is that this cellphone's battery is non-replaceable so you can't change it when it begins losing capacity, although with so much capacity you will probably buy a new cellphone before it becomes an issue.

If you want a phone for work, will use it as a social phone, will use it as a gaming device or want this device to take lots of photos, this phone is definitely a good choice for you.
