Samsung has long shortened the list of pre-installed software, and now you have the ability to set up programs. So buying Galaxy S21 Plus, you get a device where you will find applications from Google, Samsung and Microsoft.

To protect your personal data on the device, the company has offered a fingerprint scanner built into the screen. This year, Samsung is betting on Qualcomm's second-generation 3D Sonic sensor. He is responsive and faster. It reacts even to wet fingers. Tests show that even if it's raining outside and your hands are wet, the trigger rate is about 75%.

The front camera is 10-megapixel. While with the main camera you can make 8K videos at 24 frames per second, creating 4K videos is possible with both the main and front.

Judging by the quality of the photos in standard mode, the South Korean company has significantly improved the algorithm for image processing. HDR-activated shots are bright, detailed and with accurate white balance. The Galaxy S21 Plus's camera does an excellent job of processing the dark and light areas of the photos. Even in limited light, you can count on beautiful shots.

The ultra wide-angle lens of the Galaxy S21 Plus is defined by many as a real find. The photos taken with him are perfect. You will be fascinated by its capabilities.

Autonomous work
