LG K51S Review

Score: 9.31/10

LG K51S is a high-end Android device released in 2020, equipped with a high speed Octa-Core CPU running at 2.3 GHz, a huge 6.5 inches screen, and two cameras, a 32 megapixels back camera and a 13 MP front camera.

LG equipped this cellphone with a MediaTek Helio P35 MT6765 system chip, which holds a high speed 2300 megahertz Octa-Core processor and a great 3 GB of RAM. The LG K51S counts with a 64 GB big internal memory and an SD card slot, which allows the user to install hundreds of apps without thinking about how much storage is left.

This device is a compact phone, considering it has a 6.5 inches display and it is only 6.5" long and 3.02 inches wide. This phone is incredibly thin and stilized, being just 0.33" thick. This phone is offerred in three different colors, blue, pink and titanium. LG has made a great design job making the LG K51S as lightweight as 6.77 oz.

The LG K51S features two cameras, a 32 MP back camera and a 13 MP front side camera. It is also able to film 1920x1080 Full HD videos at 30 fps.

This cellphone includes a interesting 6.5" display with a 720 x 1600 resolution, which makes all photos and videos look very nice.

The LG K51S comes with a huge 4000 mAh non-removable battery that can keep this device running for many hours and even reach the end of the day without charging it at all. An issue to consider is that this phone's battery is non-replaceable so you can't change it when it starts to last shorter, even though with so much capacity you will probably replace this phone before that becomes an issue.

This cellphone counts with wifi capability (which can be shared with other devices as a mobile hotspot), LTE-A 4G really quick connectivity and also HSPA+ data connection (which is a lower speed 4G technology) and fast 3G data connection, over HSDPA and HSUPA technologies. This cellphone comes with 2 Nano SIM cards so it's able to use two different phone lines and even different carriers at the same time.

The LG K51S also comes with a wide variety of great features as Biometric fingerprint, NFC, Bluetooth (5.0 ) and GPS Geolocation, and multiple sensors like Light Sensor, Proximity Sensor, Accelerometer, Gyroscope and Compass.

It doesn't matter whether you need a work cellphone, want it to take plenty of pictures, will use it for playing games or want a social cellphone, this cellphone is probably the correct option for you.
