Reviews

Techradar wrote about the S21: "The Galaxy S21 isn’t the star of Samsung’s S series in 2021, like we’ve been used to for most of the past decade, but it’s a solid smartphone choice with an impressive camera, powerful internals and great battery life. If you want the best of the best, look to the Galaxy S21 Ultra; but if you want a handset that’s cheaper than the Galaxy S20 was at launch, with a whole load of premium features, the Galaxy S21 is a delight to use, and will do you proud."[13]
