Display:1.4 ", 450x450 px, Super AMOLED
Body:aluminium, IP68
Health:heart rate monitor, tonometer, ECG, oxygen in the blood, stress level
Sports and tourism:swimming mode, GPS
There is a model with a 40mm and 44mm display (differences in dimensions and colors). Wear OS with support for Google services and popular Android applications. 90 sports modes. A large number of built-in sensors including the BioActive sensor.
Not suitable for diving or swimming in salt water. Models with an LTE module were released for the US and European markets (not for the CIS countries). Not compatible with Apple products, models without Google services and Android GO.

the 44-mm version of Samsung's flagship watch for 2021 comes with a 1.4-inch Super AMOLED display boasting a resolution of 450x450 pixels and increased dimensions of 44.4x43.3x9.8 mm, while weighing 30.3 g. Along with its increased size, the battery capacity has also grown to 361 mAh, although it still offers up to 40 hours of autonomy with active use. That's essentially all the differences from the 40-mm model.

The watch is housed in an aluminum case with military-grade MIL-STD-810 and water resistance IP68, meaning it’s not afraid of shocks, drops, and underwater immersion. The silicone straps hint that the gadget is more suited for sports and an active lifestyle than as a stylish accessory with a business suit. The main features of the Samsung Galaxy Watch4 can be considered the Wear OS operating system, jointly developed by Samsung and Google, the Exynos W920 processor, increased memory (1.5 GB of RAM and 16 GB of internal storage), as well as the new Samsung BioActive sensor, responsible for health and sports tasks.

Thanks to it, the device becomes your personal doctor and coach, as it supports more than 90 sports modes, can perform ECGs, measure heart rate, blood pressure, and blood oxygen saturation levels, monitor sleep, and even determine body composition in real time, including the amount of fat, skeletal muscles, and water in the body. In addition, the watch is equipped with a GPS module, microphone, and speaker for making calls without a phone, and an NFC chip for contactless payment using Samsung Pay.

Model overview based on user reviews  
The Samsung Galaxy Watch4 40mm is a stylish and functional smartwatch that offers a range of features for health and fitness enthusiasts. It runs on Wear OS, providing a smooth interface and compatibility with Android smartphones, though it is not compatible with Apple products. The watch includes numerous sensors for tracking heart rate, blood pressure, ECG, and blood oxygen levels, along with a variety of sports modes and a vibrant Super AMOLED display. However, users frequently mention the watch's low battery life, often requiring daily charging. The design is praised for its durability and aesthetics, although some users find the strap less durable. Despite some issues with sensor accuracy and connectivity, the watch is generally well-received for its comprehensive functionality and ease of use, making it a strong alternative to other smartwatches on the market.

great model, love it
14 May 2023 
A fantastic model, up-to-date for today! After using the Gear S2, the leap in performance is enormous. The large display is of very high quality, and the operating system is awesome. Lots of features and sensors. It's been two months, and I actively use most of the functions. Body composition tracking, heart rate monitor, very detailed workout recording (including elevation changes on the route if running or cycling), calls (the speaker is good, and the microphone is reliable, you can talk directly from the watch), notifications. I'm very pleased with the presence of Google Pay. It's a special thrill to control it with hand gestures - answering/declining a call, launching an assigned function (for me, it's Google Pay) is quite convenient, especially when your hands are full. Battery life is great! With all the features turned on, like Wi-Fi, automatic workout tracking, heart rate monitor, gestures, always-on display, the watch lasts for two days of active use. And, of course, the watch is very stylish! Both the overall appearance and the look of the Samsung watch faces. I highly recommend buying it!
Battery, screen, workouts, calls from the watch, numerous sensors, gesture control, Google Pay, Samsung watch faces, built-in memory (6 GB available, enough for several offline playlists in the YouTube Music app).
The watch is very comfortable and almost unnoticeable when worn, at least on my wrist.
A small downside is that when measuring body composition, you have to tighten the strap much tighter, about 4 notches more than when wearing it. Otherwise, it complains and asks you to "press the watch closer." However, this only takes about 20 seconds a day and doesn't cause much discomfort.

This is a wonderful choice for people, like joking stylish and functional year.

This anniversary is hostile with its design and functionality. The screen is one of the best, like I'm a bachelor at the birthdays, and a body of preparations from the finest materials, so that it can be made resistant to fraying.
a wonderful screen, the case is resistant to sagging, you can win as a bluetooth headset to connect to the dialer if the phone is near another room
that sound is drastic, the microphone is bad, the ECG does not work, the charge lasts for 1.5-2 days, after a few months the GPS stopped catching satellites
EcoCatuse Samsung Galaxy Watch4 40mm more than year
I adore Samsung phones, but the watch is a misunderstanding, I had to return it
16 February 2022 
compared to the Apple watch, it sucks.
nothing
when you turn your hand, it sometimes activates intermittently
when you move your hand sideways - on Apple, the screen blurs to hide content - Samsung doesn't have that
pulse reading is inconsistent - for example, on the blood pressure monitor it's 120 - the watch slowly starts from 80...
pulse is 80 - the watch continues to show, for example, 100 and so on.
can't measure ECG - access to the required app is blocked in Ukraine even if you download the APK from the internet
battery runs out in a workday
reacts strangely to screen touches - not always adequately
menu visualization - like in Nokia from 2006

Runs on Wear OS

The Samsung Galaxy Watch4 is a feature-packed armor-piercing smartwatch from Samsung with a shock-resistant case, wireless charging, a comprehensive Samsung BioActive body monitoring sensor and Wear OS operating system, developed by the Korean giant in collaboration with Google. That is, on board there is a familiar set of Google services and applications that many users are used to seeing on their Android smartphone. In addition, the watch is dressed in an aluminium case with MIL-STD-810 military protection and IP68 moisture protection, that is, they are not afraid of bumps, falls and diving under water.

NFC chip for contactless payment

The fourth generation Galaxy Watch is powered by an Exynos W920 dual-core processor with 1.5GB of RAM and 16GB of built-in storage. Their communication capabilities include Wi-Fi 4 and an NFC chip for contactless payment. This version does not have an LTE receiver, so you can only get information on the built-in Super AMOLED screen, however, due to the built-in microphone and speaker, the watch can be used to receive voice calls from a smartphone. The battery life of the Galaxy Watch4 Classic depends on the specific usage scenario: in normal mode with GPS turned off, the battery lasts about 40 hours, and in active mode, the battery can last up to a day. In addition, the watch is equipped with a GPS module, a microphone and a speaker for making calls without a phone and an NFC chip for contactless payment for purchases using payment systems from Samsung and Google.

Large number of built-in sensors including BioActive sensor

In the role of a wrist trainer and tracker, the watch proves to be a solid five, there is nothing unexpected. They can measure blood pressure, ECG, blood oxygen levels, count pulse, monitor sleep quality, record an increase in stress levels, and also keep a women's calendar. The new Samsung BioActive sensor is able to analyze body composition in real time, including fat, skeletal muscle and water. More than 90 sports modes are waiting for fans of an active lifestyle, from the usual running and walking to basketball, skiing, swimming and some martial arts. The 5 ATM (IP68) waterproof case makes it possible to swim in the pool or wear them in the shower, but the manufacturer does not recommend diving in them or swimming in salt water.
