Editor Rating

Samsung Galaxy S21 5G is the base model of the popular Galaxy S series smartphones sold by the Korean brand, which gets a completely new design and solid build quality. The frame of the device is made from lightweight aluminium, while the rear panel is still plastic. The camera module has been trimmed down to sit inside a slim rectangle that juts out of the top left corner. While the rear panel is given a smooth matte finish, the camera module gets a metallic finish to make it stand out against the backdrop. On the front, you get a vibrant display that is protected by Corning Gorilla Glass Victus and features a small cutout for the selfie camera.


Bottom Line

Samsung Galaxy S21 5G is the latest upgrade to the popular Galaxy S series, which features an amazing display, a super fast processor, a versatile camera array and a small and relatively fast-charging battery.
