Samsung Galaxy S21 Review

Score: 91.8 / 100

Samsung Galaxy S21 is a wonderful Android cellphone launched in 2021, counting with a 6.2" screen, an extremely powerful Octa-Core CPU clocking at 2.84 GHz, a 12 megapixels back side camera and a 10 MP front side camera. That's all? No, it's just the starting point.

Apparently Samsung decided not to care much about the weight in this 6.03 ounces cellphone. The S21 has an inspired design, with a thickness of just 0.31". This device is quite a compact cellphone, considering it has a 6.2 inches display and it has just 5.97" long and 2.8 inches wide. This device is offerred in multiple color variations like gray, phantom pink, violet and white. This phone construction is a combination of Plastic and Aluminum .

Samsung ships the S21 with a very fast Octa-Core CPU speeding at 2.84 GHz, bundled in a Qualcomm Snapdragon 888 system chip with a great 8 GB RAM. A key feature of the S21 is the 128 GB astonishing internal storage and while it doesn't have an SD card slot, it it is more than enough to install lots of applications, games, songs, pictures and videos without having to worry about how much memory is left.

This cellphone features two cameras, a 12 megapixels back side camera and a 10 mega-pixels front facing camera. this phone's back side camera has a maximum F1.8 aperture so it can shoot excellent photos even in poor lighting situations. It can also shoot 7680x4320 videos at 24 fps, and slow motion videos in 1280x720 (HD) up to 960 fps (32 times slower than regular videos). The camera also has auto-focus.

The Samsung Galaxy S21 has a high-tech 1080 x 2400 6.2" screen, which makes everything look beautiful and brightful.

The S21 has wi-fi connection (and it can be shared with other devices around, acting as a router), 5G cutting edge connectivity, 4G LTE-A ultra fast internet connection and also HSPA+ internet connection (which is a bit slower 4G technology) and 3G fast data connection, using HSDPA and HSUPA technologies. The Samsung Galaxy S21 works with a Nano SIM card to connect to GSM networks.

The Samsung Galaxy S21 also features a lot of cool features such as Fingerprint Identification, Face unlock, Wireless charging system, NFC (to trigger actions, transfer data or make payments by holding your cellphone close to another NFC device or tag), Bluetooth (5.0 ), GPS (Global Positioning System) and Radio, and plenty of sensors like Light Sensor, Proximity Sensor, Accelerometer, Gyroscope, Barometer and Compass.

This phone has a 4000 mAh amazing Li - Polymer non-removable battery, enough to provide this device with an amazing battery life. An issue to evaluate is that the S21's battery isn't removable so you can't throw it away and buy a new one when it begins to have trouble holding its charge, even though with such a huge battery size you will probably replace this cellphone before that becomes an issue.

Samsung is offering the S21 for 722 dollars, which is not a very good offer for comparing with other similar cellphones. If you want it for work, want it to take plenty of photos, want a social phone or need a phone to play lots of games, you will probably be very happy with this phone. Samsung sells the S21 with Ejection Pin and C to C Data Cable.
