"The Samsung Galaxy S21 is a series of Android-based smartphones designed, developed, marketed, and manufactured by Samsung Electronics as part of its Galaxy S series. They collectively serve as the successor to the Galaxy S20 series.The lineup comprises three devices, with the Galaxy S21 being the least expensive with a smaller screen size and a (plastic) polycarbonate back. In contrast to the Galaxy S20+, the Galaxy S21+ is very similar to the S21 spec-wise, with the exception of a larger display, higher battery capacity, and back glass instead of plastic. The Galaxy S21 Ultra has an even larger screen size, battery, and a host of other improvements over the other models, including a more advanced camera setup highlighted by its 108 MP main sensor with laser auto-focus and a higher resolution 1440p display. The S21 Ultra is also the first phone in the Galaxy S series to support the S Pen, albeit sold separately and with limited functionality."
