Announcement of flagship smartphones Samsung Galaxy S21, S21 Plus and S21 Ultra

The announcement of TWS inserts as a seed before the show of the family of top smartphones has already become a tradition for Samsung. For the Old New Year of 2021, Galaxy Buds Pro became such headphones, announced on the very eve of the debut of the "mobile phones" of the S21 series.

Aesthetically, the Pro version of the "in-earphones" is close in spirit to the headphones Live (https://ek.ua/SAMSUNG-GALAXY-BUDS-LIVE.htm ), and in fact it has more similarities with the Buds+ model (https://ek.ua/SAMSUNG-GALAXY-BUDSPLUS.htm ). The tiny headphones managed to accommodate two speakers — 11 mm low-frequency and 6.5 mm high-frequency drivers. Thanks to this arrangement, high sound quality is achieved. An important emphasis is also placed on the quality of calls, during which a system of three microphones cuts off unnecessary noise, and a special air chamber neutralizes the effect of wind blowing.

For the most complete immersion in music, the headphones use the active noise reduction function with a configurable noise removal intensity. At the same time, the headphones recognize the user's speech and automatically turn on the transparency mode if he speaks to someone (Ambient Sound). Another useful feature is instant switching from one Samsung device to another. For example, from the video viewing mode on a tablet (https://ek.ua/k30.htm ) to receive an incoming call on the phone (https://ek.ua/k122.htm ) (when the headphones are connected to two of these devices at the same time).

Outside of the time of presence in the user's ear, headphones live in the "nests" of the charging case. Just 5 minutes of staying in them extend the battery life of the headphones for a whole hour. In general, Galaxy Buds Pro will be appreciated by both fans of Samsung products and ordinary fans of high-quality music. The model is able to impose strong competition in the fast-growing segment of TWS inserts.

The usual Galaxy S21 without any prefixes in the expanded name is an example of a smartphone balanced on all fronts in a relatively compact case (by modern standards of "gigantomania").

The model is recognizable against the background of "classmates" in the S21 line with reduced dimensions and the material of the manufacture of the "back" — it is made of polycarbonate here. At the same time, from a tactile point of view, the device does not feel much worse than its older counterparts — the smartphone case does not slip in the hand and does not collect fingerprints. The front panel of the gadget is occupied by a Dynamic AMOLED 2X screen with a diagonal size of 6.2", a resolution of 2400 x 1080 pixels and an adaptive refresh rate from 48 to 120 Hz. A fingerprint scanner with lightning responsiveness lives in the sub-screen layer.

In the version for the vast majority of markets, the Samsung Galaxy S21 comes with an Exynos 2100 mobile processor, which is made according to the norm of 5 nm. The volume of RAM of the smartphone is 8 GB, and the capacity of the internal storage starts at 128 GB. It is noteworthy that in the S21 generation, the memory expansion slot was abandoned — from now on, users will have to approach the choice of the capacity of the regular drive more legibly, so as not to experience a lack of free space in the future.

The main camera unit of the smartphone is designed in the Contour Cut style — it seems to "flow" from the side metal frame of the case and is its visual continuation. Under the wing of the rear photo module there is a trio of image sensors: a stabilized 12 MP master sensor with Dual Pixel phase autofocus, a 12 MP ultra-wide and a 64 MP TV speaker with triple optical zoom and a built-in stub. The resolution of the front camera "in the forehead" of the smartphone screen is 10 MP.

The Samsung Galaxy S21 has a 4000 mAh rechargeable battery, which supports both fast wired, wireless, and reverse charging. But the power adapter is no longer provided in the standard configuration of the model, as well as wired headphones. The manufacturer justifies their absence by taking care of the environment. The model is available in four variations of body colours: purple phantom, grey phantom, pink phantom or white phantom.

The fundamental difference between the "plus" modification of the Samsung Galaxaxy S21 from the original is, of course, the increased size, which is due to the use of a much larger diagonal screen.

In the Plus version, the Dynamic AMOLED 2X matrix was stretched by 6.7". The screen of the smartphone is flat (without curved sides), its resolution corresponds to the FullHD+ format (2400 x 1080 pixels), besides, the display works with an adaptive frequency from 48 to 120 Hz (flexible adjustment of the refresh rate allows you to keep the battery charge longer). In the centre of the upper segment of the front panel of the mobile gadget, there is a hole for the 10 MP front camera.

The photo module on the glass back of the device looks much more interesting. A neat die with it "flows out" from the steel frame of the case and contains three photographic "eyes". The leading image sensor of the main camera is shooting at a resolution of 12 MP, providing the user with a Dual Pixel autofocus system and optical stabilization. It is accompanied by 12 MP ultrashire and 64 MP stabilized TV speaker. In general, the cameras here are made at the highest level and are worthy of the top lines of the podium in the discipline "Mobile Photography".

The "iron" combination of the Exynos 2100 octa-core chipset (or Qualcomm's 888th "dragon" in the American version of the device), 8 GB of RAM and 128/256 GB of ROM (without support for memory cards) vouches for the high performance of a smartphone with an eye even for the distant future. The device was loaded with an under-screen fingerprint scanner, a set of up-to-date wireless communications (including Wi-Fi 6 and a 5G modem), a good 4800 mAh battery (supports accelerated charging by wire and reversible wireless "refueling"). The smartphone case is protected from external influences in accordance with the requirements of the IP68 dust and water protection standard.

The smartphone "for all the money" from Samsung is named Galaxy S21 Ultra. He is the most technologically "savvy" in the newly minted line of flagships of the sample of the beginning of 2021.

Recognizable features of the model's appearance are formed by a screen with small bends on the sides, which has diagonal dimensions of as much as 6.8". The substrate for it, as before, is the Dynamic AMOLED 2X matrix. Yes, not simple, but with an increased image resolution (3200x1440 pixels), a wider range of adaptive refresh rate (from 10 to 120 Hz), a high threshold of peak brightness of 1500 nits. An important difference between the Ultra and its peers from the S21 squad was the support of the S Pen thanks to the additional Wacom touch layer.

In the "under-the-hood" equipment, the Samsung Galaxy S21 Ultra is completely identical to the brothers of the series. Depending on the regions of sales, the smartphone is equipped with Exynos 2100 or Snapdragon 888 processors, the minimum amount of RAM on board is 12 GB, and the capacity of the internal storage varies from 128 to 512 GB. Surprisingly, the model no longer does business with microSD flash drives, so it is necessary to approach the choice of a suitable amount of memory wisely.

A truly outstanding thing is the main camera unit of a mobile device. The smartphone sports a 108 MP leading sensor, 12 MP ultra-wide with autofocus and two 10 MP telephoto lenses each (the first provides 3x optical approximation, and the second provides 10x). Moreover, the model is able to shoot 4K video with a frequency of 60 fps for all photo modules, including an island front-end with a resolution of 40 MP.

The model supports Galaxy Smart Tag accessories — thanks to a small tag, it will be easier to find devices or things. The smartphone is also notable for a number of other points of the programme: a separate flattering words deserve an under-screen fingerprint scanner, AKG stereo speakers, an accelerated battery with a capacity of 5000 mAh, water protection of the device body according to the IP68 standard. Finally, for Samsung Galaxy S21 Ultra, two basic colours are provided (black phantom, silver phantom) and three options of "casters", which can be ordered directly from the manufacturer.
