The
Samsung Galaxy S21
is a series of high-end
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 first three smartphones were unveiled at Samsung's Galaxy Unpacked event on 14 January 2021, while the Fan Edition model was unveiled at Samsung's CES on 3 January 2022.
The S21 series consists of the base
Galaxy S21
model, the larger
Galaxy S21+
model, the high-end
Galaxy S21 Ultra
model, and the mid-range
Galaxy S21 FE
model. Key upgrades over the previous models, in addition to improved specifications, a display with a 120 Hz adaptive
refresh rate
, an improved camera system supporting
8K video
recording (7680×4320) for the first three models, and a super-resolution zoom of 30?100x, for the ultra model.
The first three phones were released in the United States and Europe on 29 January 2021, while the Fan Edition was released globally on 7 January 2022. The Galaxy S21 FE, S21, S21+, and S21 Ultra launch prices started at $699.99, $799.99, $999.99, and $1079.99, respectively.
The Galaxy S21 was succeeded by the
Galaxy S22
, which was announced on 9 February 2022.

History
[
edit
]
S21, S21+, and S21 Ultra
[
edit
]
The lineup of the first three devices was unveiled at Samsung's
Galaxy Unpacked
event on 14 January 2021. The three devices served as the successors of the 2020 models. All devices' design scheme has changed drastically, redesigning the massive rear-camera module for a slimmer camera module incorporated with the buttons and a uniform appearance for the S21, S21+, and S21 Ultra. The base model possesses a (plastic) polycarbonate back, the only model of the three devices to attain the change. The base model attains similar specifications to the S20.
[1]
The S21+ retains the specifications and design of the regular S21, in contrast to minor differences. It serves as the successor to the S20+.
[2]
The S21 Ultra serves as the high-end model of the S21 series, integrated as the professional version of the lineup, and successor to the S20 Ultra. The phone became the first of the S-Series lineup to have S-Pen support, with limited functionality.
[3]
The S21 series discontinued sales once the
Galaxy S22
were released.
[6]
The phones were released on 29 January 2021.

S21 FE
[
edit
]
The "Fan Edition" follow-up was unveiled at Samsung's CES 2022 event on 3 January 2022. The S21 FE serves as the successor to the S20 FE, a series of mid-range variants of their corresponding Galaxy S lineup upon launch. The Fan Edition maintains the majority of the specifications and design of the S21, with slight discrepancies to meet its lower price value.
[8]
The phone was originally planned to be released in October 2021 but was delayed due to the
2020?present global chip shortage
. The S21 FE was released on 11 January 2022.
[9]
It's battery had 4500mAh (25W wired and 15W wireless). It was also equipped with a 6.4" 1080x2340 display which included under display fingerprint.
[10]
Lineup
[
edit
]
The lineup comprises four devices, with the Galaxy S21 initially being the least expensive with a smaller screen size and a polycarbonate (plastic) 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 glass back 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.
[11]
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.
[12]
Design
[
edit
]
The Galaxy S21 series has a design similar to its predecessor, with an Infinity-O display containing a circular cutout in the top center for the front selfie camera. The S21 and S21 FE's back panel is reinforced poly-carbonate (plastic) similar to the
S20 FE
and
Note 20
while the S21+ and S21 Ultra use Gorilla Glass Victus.
[13]
The rear camera array has been integrated into the phone body except for the S21 FE which is made out of reinforced poly-carbonate integrated instead on the back cover and has a metallic surround; the S21 Ultra has a carbon fiber camera surround for exclusive colors.

The S21 and S21+ have similar camera setups to their predecessors but benefit from improved
software
and image processing. Both have a 12 MP wide sensor, a 64 MP telephoto
sensor
with 3x hybrid zoom, and a 12 MP ultrawide sensor. The S21 FE also has a similar camera setup to its predecessor but benefits from improved software and image processing. It has a 12 MP wide sensor, an 8 MP telephoto sensor with 3x optical zoom, and a 12 MP ultrawide sensor. The S21 Ultra has a new HM3 108 MP sensor with several enhancements over the previous HM1 108 MP sensor, including 12-bit HDR. It also has two 10 MP telephoto sensors with 3x and 10x optical zoom and a 12 MP ultrawide sensor.
[20]
The
front-facing camera
uses a 10 MP sensor on the S21 and S21+, 32 MP sensor on the S21 FE, and a 40 MP sensor on the S21 Ultra. 4K@60 recording is supported on the ultrawide camera on the S21, S21+, and S21 FE and all cameras on the S21 Ultra. All cameras are Samsung except 12MP Ultra Wide on S21 Ultra and 10MP front on S21 and S21+, which are both made by Sony, and the 8MP Telephoto on the S21 FE which is made by SK Hynix.
The Galaxy S21 series can record HDR10+ video and support
HEIF
.
[15]
Moon photo controversy
[
edit
]
Users discovered that the Scene Optimizer included with Samsung Galaxy S21 and later phones use artificial intelligence to identify the
Moon
and add details that the camera is not capable of capturing, based on a library of existing moon photos.
[21]
[22]
However, this was disputed by Samsung, claiming that they have an AI enhancement algorithm that adds detail to your moon photos.
[22]
Supported video modes
[
edit
]
The Samsung Galaxy S21 series supports the following video modes:
[15]
Still frames extracted from high-resolution footage can act as standalone photographs.
[26]
Software
[
edit
]
The first three S21 phones were released with
Android 11
(One UI 3.1) and
Google Mobile Services
, with Samsung's
One UI
software. While the S21 FE was supposed to be released with the same Android version and One UI skin, due to it being delayed all devices are now updated with
Android 12
(One UI 4.0) instead.
[27]
They all use
Samsung Knox
for enhanced device factory reset protection (FRP) security, and a separate version exist for enterprise use.
[28]
The first three S21 series smartphones were updated to
Android 12
and One UI 4 on 15 November 2021.
[29]
[30]
Samsung added a "repair mode" to its Galaxy S21 on 28 July 2022, hiding users' data when they entrust an ailing device to a technician.
[31]
The One UI 5 update based on Android 13 began rolling out to S21 devices on 7 November 2022.
[32]
Reception
[
edit
]
The Verge
'
s review, by Dieter Bohn, praised the S21 Ultra's punchy display, fast performance, long-lasting battery life and the general improvements to the camera system, likening the latter to that of the
iPhone 12 Pro Max
's; however, Bohn did note that the phone's glass back is slightly more susceptible to minor scratches.
[33]
Android Authority
's review by David Imel noted the Samsung's Galaxy S21 Ultra "is a powerhouse smartphone" and that "the camera system in Samsung Galaxy S21 Ultra is one of the best you can get on Android".
[34]
Matt Sweder at Techradar gave a positive review noting its "mesmerizing design" calling it "Samsung’s best-looking phone ever" and how "phenomenally powerful" the camera is, but also went on to criticize the price and lack of
microSD
card slot, and questioning the stylus support, which is a separate purchase, with nowhere to put the S Pen on the phone itself.
[35]
Criticism has been aimed at the lack of a
charger
and
memory card-expandable storage
, the latter of which existed on the preceding Galaxy S20.
[36]
In 2018, Samsung made fun of
iPhone
's lack of the same features and an
audio connector port
in a series of
commercials
for the
Galaxy S9
named "Ingenious", where unhappy iPhone customers confront an
Apple Store
employee over the lack of functionality that the Galaxy S9 was equipped with, a feature which has since been removed from all Galaxy phones.

Following Apple
, Samsung decided not to include a wall charger or earphones when selling the Galaxy S21 series of smartphones, the reasoning being that "Samsung believes the removal of earphones and charger plugs from our in-box device packaging can help address the growing e-waste problem and unnecessary duplication of these items". However, reaching the highest charging rate possibly requires a new charger with separate packaging and shipping with a standalone environmental footprint.
