We've seen mockups of Samsung's upcoming trio of flagship phones, the Galaxy S21 lineup. And now, with the release date a month away, we've seen what appears to be the real deal.

Leaker Max Weinbach has released a clip that is supposedly the official teaser for the Galaxy S21, Galaxy S21 Plus, and Galaxy S21 Ultra. According to this exclusive Android Police video, the Galaxy S21 and S21 Plus share many similarities, while the S21 Ultra stands out with its unique design.

Specifically, the Galaxy S21 Ultra shown in the clip posted by Weinbach features curved edges along the figure (at least if this year's Galaxy S20 Ultra is anything to go by), the largest of the three S21 models. In contrast, the Galaxy S21 and Galaxy S21 Plus feature flat displays; all three models have a circular camera cutout in the center of the screen, a feature carried over from the S20 lineup. [But it is the Galaxy S21 Ultra's camera array that will attract the most attention. The video shows a rear camera setup with four lenses: three lenses overlap on the left side of the array, while another lens is off to the side. According to Weinbach, this is a single 10x zoom periscope camera. The stacked cameras are a 108MP main shooter, a 12MP ultra-wide angle lens, and a 10MP telephoto camera (3x zoom). Samsung also plans to include a time-of-flight sensor in the S21 Ultra, Weinbach said. [The Galaxy S21 and S21 Plus videos do not feature a second telephoto lens. Instead, these phones feature only three rear cameras, according to Weinbach, which are a 12MP main shooter, a 12MP ultra-wide camera, and a 64MP telephoto lens.

There really are no noticeable physical differences between the Galaxy S21 and Galaxy S21 Plus depicted in these videos; according to Weinbach, Samsung differentiates by featuring different screen sizes and battery capacity.

The design depicted in the video is striking. The phone's frame extends all the way to the camera bump on the back, and at least in the S21 and S21 Plus teasers, it is a different color than the rest of the phone. For example, in the Galaxy S21 video, the camera array is a copper color, although Weinbach describes it as a phantom violet color.

The Galaxy S21 Ultra has a black camera bump, which blends in with the black design of the model in the leaked video.

A recent trend in cell phone design has been the use of large rear camera arrays that stand out above the rest. The design Samsung has chosen for the Galaxy S21 seems to make that feature even more prominent, rather than trying to hide it. Let's see how would-be shoppers react to the new look when Samsung actually unveils the new phone.

That could happen quite soon. Other Galaxy S21 rumors have pointed to an earlier than usual launch for the phone, with some leakers suggesting that Samsung will unveil its new device on January 14. That is the same date cited by Weinbach, who further predicts that the new S21 model will hit store shelves on January 29.

Weinbach adds to expect a lower price than last year's model, which started at $999 for the Galaxy S20. If true, that would be a welcome start to the new year.
