Samsung has introduced the S21, S21 Plus and S21 Ultra as successors to the S20. The latest technology has been used in this smartphone. The Samsung s21 Ultra is currently one of the most powerful smartphones. The camera block is a little higher than the mobile body, which can cause light dust to accumulate on the side of the camera. The power button and volume button are placed on the right side of the mobile. The SIM card tray is placed at the bottom of the mobile. This device does not have the opportunity to use a micro SD memory card. It is one of the first smartphones with WiFi 6E.
The Galaxy S21 Ultra has a 6.8-inch dynamic AMOLED display; the screen resolution is QHD – 3200 x 1440 pixels. The default mode is 2400 x 1800 pixels, but you can safely turn on QHD. The resolution has almost no effect on battery life. It has a unique feature of the 120 Hz refresh rate. As a result, users can use the mobile very smoothly.
The S21 Ultra has four back cameras – an ultra-wide-angle 12MP with f / 2.2 aperture, a 108-megapixel wide-angle module with f / 1.8 aperture, and two telephoto lenses. The smartphone now can shoot video in 4K and 60 frames per second on all cameras, including the main and front ones. The selfie camera has also been updated with a 40-megapixel resolution with f / 2.2 aperture.
The phone is running on the operating system, Android 11 (One UI 3.1). Qualcomm Snapdragon-888 has been given as the chipset for the Chinese and American markets and Exynos-2100 for the international market. It is developed using 5-nm technology; this means an increase in performance and longer battery life for the user. The mobile comes with 128GB, 256GB, 512GB ROM variants of 12GB and 16GB RAM.
