"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 Samsung Galaxy S20 series.The lineup comprises four devices, with the Galaxy S21 initially being the least expensive with a smaller screen size and a (plastic) polycarbonate back which then is undercut later on by the Galaxy S21 FE with the same material minus the camera bump being also polycarbonate than metal. 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."
