Model overview based on user reviews  
The Samsung Galaxy S21 256 GB is a smartphone that stands out for its excellent camera quality, offering numerous settings for customization and capturing good selfies. It is powered by a robust processor, ensuring quick performance without lag, making it suitable for various tasks. The phone features a bright display with high picture quality, enhancing the viewing experience. Its compact size makes it convenient to hold and use, while the quick charging capability and reverse wireless charging add to its practicality. However, the phone's battery life is a concern for some users, as it drains quickly, especially at 120Hz. Additionally, the device tends to heat up during charging and prolonged use. The plastic back cover may not appeal to those seeking a more premium feel, and there are some software and UI issues reported. Despite these drawbacks, the Samsung Galaxy S21 256 GB remains a strong contender in the smartphone market, offering a blend of performance, design, and camera capabilities.

I definitely recommend it, but not for everyone.
25 March 2021 
Update the software, remove or disable unnecessary things, set up notifications, configure operating modes and the issue of autonomy will disappear. After all the optimizations, my device lasts for a day and a half. 1.5-2 hours of music a day, often instant messengers and calls, 2 online banks and the use of an Android car alarm application. Plus, the smart device works in tandem with the Samsung Galaxy Watch 3 quite successfully. Something like this.
Fast device, eSim support, good customizability
Build quality, minimalism of the kit
Alexey Razovuse Samsung Galaxy S21 256GB less than month
High-quality flagship smartphone without obvious flaws
19 July 2022 
I switched from Huawei Nova 5T to this model because I wanted a compact smartphone with good battery life, a camera, and performance. Honestly, I was hoping for some "wow" effect from buying the S21, but in reality, even though the Huawei is a couple of years older and 2.5 times cheaper, the impression of switching to the S21 is quite ordinary: yes, the screen is better, yes, the number of decent shots from the main camera is higher and their quality does not raise any complaints, yes, it feels better in hand. But: the interface is definitely not more convenient than EMUI, the speed is higher, but in everyday use, it is almost unnoticeable, battery life, despite the OLED screen and more capacious battery, is not significantly higher (4.5 hours of screen time versus 5-5.5).
1. Compact size
2. Bright screen with very good picture quality
3. Good camera
4. Sufficient performance for everyday tasks
1. There are shortcomings in One UI
2. Battery
3. The sensor in the screen is still slower compared to classic ones
Konstantin Katarskiyuse Samsung Galaxy S21 128GB few months
Years go by, but it gets worse...
22 January 2022 
Everything is very bad. It seems like there are innovations after innovations, yet the phones are getting worse and worse. SEVEN years of development and technological progress, THREE cameras, more modern software, etc., yet on the expensive flagship - S21 you get a blurry [censored], while on the ancient, like a mammoth, S7 Edge - a clear photo that is almost 3 times smaller in file size. I thought, well, okay, accidents happen, I take a night photo, which Samsung boasts so much about, and I don't see a difference. No, there is a difference, but to my ordinary eyes, not being a photographer, it's not noticeable. SEVEN YEARS, THREE CAMERAS, AND THIS IS IT?! How the heck did you manage to degrade so much? Back when I was using the S7, I bought a Galaxy Watch, and since then, I've had a third phone from Samsung, and EVERY SINGLE TIME I connect to another phone with the same Samsung account, the watch refuses to connect without resetting (screenshot below), and this hasn't been fixed to this day. I specifically checked, updated the watch, updated the app on the phone, and it still doesn't work. And this isn't the only complaint about the software, they removed convenient features for some reason. Before, you could record a call using the phone app itself, now you can't. Before, you could set any sound for notifications, now you can't, only the dull system ones. Before, you could enable maximum power-saving mode, which allowed the phone to last up to a week, but now you can't.

I used to be able to connect headphones to both my phone and tablet at the same time, watch YouTube on one, and easily hear and answer calls on the other. Now, the headphones work either with the S21 or everything else. On the other hand, when it comes to codes from messages, there is stability; the phone still hasn't been taught to suggest entering them, so I have to go into SMS and manually retype them, just like seven years ago. Thanks, Samsung, for the care. I've used Samsung since the first Galaxy Note, but now I just don't see any reasons to buy Samsung phones anymore. The in-screen scanner works intermittently, cameras either shoot roughly the same or worse than SEVEN YEARS AGO, the design is average for Android and unremarkable, especially compared to Apple, reverse charging is inconvenient and useless, fast charging is only 25 watts compared to Xiaomi's 120, and you have to buy it separately. The ecosystem is laughable, especially considering that AirPods worked with my Samsung phone better than Samsung's own headphones...
