Samsung Galaxy Watch4 40mm LTE
Display:1.2 ", 396x396 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 colours).
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 representative of the fourth generation of Samsung smartwatches is a mid-budget solution in a 40mm case with an LTE module available. The presence of the latter ensures support for e-SIM (operational in Western Europe and the USA), and together with the built-in speaker and microphone, it allows for making voice calls without a mobile phone nearby. The model is equipped with a proprietary dual-core Exynos W920 processor with a clock speed of 1180 MHz and 1.5 GB of RAM, and this "hardware" runs on the Wear OS operating system.

Among other features, the latter supports contactless payments (both Samsung Pay and Google Wallet). The Samsung Galaxy Watch4 40mm LTE smartwatch features a 1.2-inch touchscreen with a Super AMOLED matrix, a resolution of 396 by 396 pixels, and several operating modes, including Always on Display. The dial is protected by Gorilla Glass DX+. The case of the wrist accessory itself is made of aluminum, which combines strength, lightness, and beauty.

The water resistance class is declared at IP68, but the model should not be used for diving and swimming in saltwater. The device's features, in addition to its GPS module and support for 97 sports modes, include a large number of measurements, including heart rate, blood pressure, ECG, blood oxygen saturation tracking (SpO2), sleep, and stress level monitoring. It should also be noted that there is 16 GB of built-in memory for music and apps, and the battery life is stated to be up to 2 days.

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
