Samsung Galaxy S21: Everything you need to know

Reading Time: 3 minutes

During the first Unpacked event of the year, Samsung announced its latest flagship smartphones: the Galaxy S21, S21 Plus, and the S21 Ultra. The new devices can effectively be divided into two categories. The first one – the S21 and S21 Plus are almost identical phones with a few differences in screen/battery size and other minor details. The second category – the S21 Ultra is the ultimate device in Samsung‘s diverse lineup of Android smartphones. It is the star of the show and we believe it’s currently the best phone available.

Samsung’s smartphones are renowned for their elegant and innovative design, and the new S21 series flagship is no different.

The curved edge, which is Samsung‘s hallmark for years, is replaced now by a flat display. All three models come with a larger camera bump that is connected to the aluminum frame of the phone. If you ask us, it’s a nice touch with a new feel. The camera bump on the S21 Ultra is the largest compared to the other two models because it has to make room for the quad camera on the phone.

There is a wide range of new colors, but as is usually the case with Samsung phones, your options will be based on which model you decide to go with. The S21 has four color options (white, pink, grey, violet), the S21 Plus has three (silver, violet, black), and the S21 Ultra has two (silver, black).

Samsung S21 and S21 Plus

As we previously mentioned the two phones are almost identical. They both have an IP68-rated body. It means the devices can survive underwater for 30 minutes. Also, S21 and S21 Plus have USB-C for charging, and a larger ultrasonic fingerprint sensor inside the display. Sadly for some, the 3.5mm headphone port was removed.

To highlight the differences, we should focus on the size of the screen. If you prefer a larger smartphone, then S21 Plus is the choice for you. It has a 6.7-inch display. The display is no longer of the WQHD+ type featured on last year’s models (Galaxy S20). Now the devices have the FHD (2400 x 1080) AMOLED screen with a refresh rate of 120Hz. It is quite good for streaming HDR videos on Netflix or Youtube.

The options for memory and storage are limited to 8GB of RAM and 128GB/256GB, respectively. Unfortunately, on all S21 devices, there is no alternative to expanding the storage via a micro SD card, which is hugely disappointing.

Both phones have three rear cameras. The primary 12MP sensor is assisted by another 12 MP wide-angle lens and a 64MP telephoto lens. The cameras can record 8K video at 30fps and 4K content at 60 fps. There’s a 10MP sensor around the front, too, for selfies and facial unlocking.

These are the first Samsung smartphones to ship without a charger and even earphones in the box.

Samsung S21 Ultra 5G

The S21 Ultra is a beast of a phone with five cameras, a 6.8-inch display featuring a Quad HD+ resolution, a 108MP sensor (ISOCELL HM3), and 16GB of RAM. The new S Pen support transforms the phone into a mini-tablet.
