Galaxy Fit 3 review



Galaxy Fit 3
The Galaxy Fit 3 is a great generational improvement and benefits from many features of the Galaxy Watch, making it an attractive choice for users on a tighter budget.

Galaxy Fit 3 review

It has been four years since Samsung released the third generation Galaxy Fit smart band; In this long absence, many probably forgot that Samsung also has a smart wristband in addition to a smartwatch, and for a while, it was even rumored that the Koreans have abandoned the Galaxy Fit product line forever.

Galaxy Fit 3, which was launched at the end of February 2024, has changed its face so much that it can hardly be considered the sequel of the previous generation; From the 31% increase in screen size, which has changed the previous very elongated form factor to more reasonable dimensions, to the two-piece strap and aluminum material of the body instead of plastic, and the addition of fall detection capabilities and ambient light sensor.

If you have had a Galaxy Fit 2 and want to stay in the Samsung ecosystem at a much higher cost than Chinese smart bands, you will not regret buying the Galaxy Fit 3; But I don’t think many people are going to upgrade now. You probably either want to know which one to choose for your first smartwatch, between the Fit 3 and the Xiaomi Smart Band 8, or you want to know if you can spend more than half the price of the Galaxy Watch 6 and get all the features and functions that make this watch one of the best. Has the market smartwatch become accessible or not?

Before we go to the features, let me tell you about the feel of the Galaxy Fit 3. Samsung’s new smart band with an aluminum body weighing only 18.5 grams is very light, comfortable, and well-made, and although it has relatively large dimensions, it fits well on narrow wrists.

The Fit 3 silicone strap, which you can get in three colors, black, white, and rose gold, is very soft and high-quality, and it has changed from the previous generation’s integrated mode, where the screen was placed inside, to a more standard two-piece model. Fastening the strap and connecting it to the wristband is done easily; Perhaps the only fault that can be found is that there are not enough holes on the strap to firmly fasten the body on narrow wrists.

Having said that, if you are the type of person who wants to monitor your health status 24 hours a day, even while you sleep, the Galaxy Fit 3 is a more logical choice of watch, because apart from the lower price (albeit at the expense of fewer features), it is smaller and weighs less. Almost half of the Galaxy Watch 6; So it won’t bother you when you sleep.

In addition, Galaxy Fit 3 benefits from the highest certificate of resistance against dust penetration (IP68) and resistance up to 5-atmosphere pressure (50 meters depth) against water penetration so that you can easily use it to record information related to swimming in the pool.

Currently, it is not possible to connect Galaxy Fit 3 to iPhone

Galaxy smartwatches and wristbands are specially optimized for the Samsung ecosystem and then for Android phones, they are usually compatible with the iPhone (with some limitations of course); But currently, it is not possible to connect the Galaxy Fit 3 to the iPhone, because the Galaxy Fit application in the App Store does not support the new generation of Samsung wristbands. So, if you have an iPhone and want to use the sports and health features of other brands for a much lower price than the Apple Watch, you have to leave the Galaxy Fit 3 out of your options for now.

Like the previous two generations, Galaxy Fit 3 uses the open-source operating system FreeRTOS, which can be considered a lighter and simpler version of WearOS. Samsung has preferred using FreeRTOS for its smartwatch because cheaper and less powerful chips can handle it well and do not lag. In addition, the life of the battery increased many times; Fit 3’s battery lasted about a week in my daily use, while continuous monitoring of heart rate, stress, and sleep was active, but Always-on was disabled, and I spent 30 minutes exercising and 15 minutes checking the time and notifications. With a day or two of charging, the Galaxy Watch 6 is fantastic.

The FreeRTOS user interface is similar to WearOS in many ways, and even the application icons are almost the same; But unlike WearOS, it does not support Google Play and the ability to install external applications, and you have to go with the same default apps; including health application, music control, phone finder, weather, calendar, timer, alarm, stopwatch, world clock, calculator and camera shutter control. Galaxy Fit 3 has almost all smartband applications; However, the possibility of downloading favorite applications may not be pleasant for some users.

FreeRTOS operating system, smooth, simple, and fast but more limited than WearOS

The Samsung Health app for the Galaxy Fit 3 is one of the most complete and useful apps that can be found on the smartwatch. In this application, you can see various information, including the number of steps, how long you have exercised in a week, the amount of calories and water consumed, and the heart rate. By tapping on each, the corresponding app will open with more data. There is also information related to the prediction of menstruation in this section, which, unlike the Huawei Watch GT4, which works based on information such as heart rate, skin temperature, and breathing, only relies on the information entered in the calendar.

Leaving aside the limitation of FreeRTOS in installing applications, during the time I was testing the Galaxy Fit 3, the operating system performed very smoothly and even appeared as good as the Galaxy Watch 6. Fit 3’s user interface is also very simple and straightforward. By pressing the physical home button once, you will return to the main screen. Pressing the button twice will open the list of workouts, where you can choose another application for this command from the Advanced Feature section of the smartband settings.

There is a long delay in sending notification messages to the Galaxy Fit 3

Galaxy Fit 3 uses simple and standard gestures to access different parts of the wristband; Swiping up shows the list of applications, swiping down shows quick settings, swiping left shows the Tile (Tile) or the applications card, and swiping right shows notifications. In the tile environment, you can add up to 12 different cards. The notification text also supports Farsi language and emoji, although it takes about 28 seconds for the message notification to be displayed on the smart band.

Unfortunately, on the Galaxy Fit 3, unlike the Galaxy Watch, there is no possibility to reply to a message, and at best, you can only send predefined replies, which are not very useful. I think it’s time for sending messages from smart watches and wristbands to become a standard, not to remain exclusive to luxury devices.

Galaxy Fit 3 does not lack in the watch face department; From the Wearable application, you can access more than a hundred watch faces with various designs and colors. If none of the watch faces catch your eye, you can use your favorite images and edit them with the application’s tools, and even change the color of the time display for better readability on any background. Samsung also lets you switch between watchfaces you’ve created by saving multiple images in the Watchfaces section and tapping on the Fit 3’s home screen.

Galaxy Fit 3 has almost all the health and sports features of Galaxy Watch 6 (except ECG and irregular heart rate measurement, which is not available in Iran), but in some features, it shows different accuracy; For example, in the heart rate test, the Fit 3 was about 5% different from the Watch 6. While I was sleeping, with both devices strapped to my wrist, the Galaxy Watch 6 reported that the blood oxygen level dropped below 90%, but the Fit 3 reported everything as normal. In the stress test, Watch 6 showed a slightly lower stress level.

In sleep monitoring, Galaxy Fit 3 appeared very accurate and provided complete statistics; including sleep duration, different stages of sleep, sleep score, and even blood oxygen level recording during sleep. If you activate the snore detection option from the application, the phone’s microphone will record your snoring sound.

Galaxy Fit 3 has over a hundred workouts to cover almost any sport you want. For some sports activities, including walking, running, elliptical, and swimming, which have just been added, it has an automatic detection mode so that if you forget to start the workout, the smart band will start the corresponding workout after a few minutes. Fit 3’s pedometer was also about 10 steps different from reality and is generally accurate.

Fit 3 is equipped with two new safety functions, fall detection, and Emergency SOS

The Galaxy Fit 3 uses two new safety features, including Fall Detection and Emergency SOS, which are present in the Apple Watch and Samsung’s WearOS-based devices. If you fall while exercising, the Fit 3 will call the emergency services or a selected person from your contact list thanks to the fall detection feature.

By activating Emergency SOS and selecting a person as an emergency contact, you can send your location to this person by pressing the button 5 times. If you have already entered your medical information, it will be displayed on the screen of the smart band.

The Galaxy Fit 3 is now equipped with an ambient light sensor to adjust the screen brightness according to the environment. Samsung hasn’t announced the Fit 3’s maximum brightness, but it seems to be around the 600 nits we’d expect from this price range.

Samsung’s new smart band uses two interesting features in the security department that may come in handy; First, you can choose a pin code for it; As long as the smart band is on your wrist, you don’t need to enter a passcode, but as soon as you remove it from your wrist, the device is locked and a PIN code is required to unlock it.

The second feature, which is enabled by default, prevents the display of notifications as long as the smartband is not attached to your wrist. For example, if you put the Galaxy Fit 3 on the table and leave it behind the table, another person cannot read the messages; Of course, if you notice that the notifications are not displayed even when you wear the smartband on your wrist, disable this feature from the security section, because there is probably an interference between the skin of your hand and the sensor.

Is the Galaxy Fit 3 worth buying?

So far, we talked about the features and capabilities that seem to put the Galaxy Fit 3 almost at the level of the Galaxy Watch 6; But the Samsung Smartband lacks some of the basic functions of the Galaxy Watch, including built-in GPS, speaker, and microphone for answering calls, sending replies to messages, installing additional applications from Google Play, Wi-Fi connectivity and LTE options, and models with different sizes to better fit the size of the watch. Different wrists. In terms of appearance, the Galaxy Watch has a more luxurious and attractive design and is more similar to a classic watch.

Considering the differences, the Galaxy Fit 3 cannot be considered a replacement for the Galaxy Watch 6. If answering calls and messages, internal GPS, installing applications and the classic appearance of the watch is not your priority, and at the same time you want the device to be attached to your wrist all the time, the battery life is satisfactory, and to spend half the price of the Galaxy Watch, the Galaxy Fit 3 at a price of about 4 4.5 million tomans is a more appropriate choice in the Iranian market; But if you don’t care about staying in the Samsung ecosystem and a bigger screen, and you just want to get a smart band for your Android phone with all the health and sports features, including swimming, the Xiaomi Smart Band 8 with a price of around 1.5 to 2 million Tomans seems like an attractive option. .

Positive points

  • Great battery life
  • Big and bright AMOLED display
  • Fall detection and Emergency SOS
  • Light, and comfortable with a soft strap and metal frame
  • Has the most important health and sports capabilities

Negative points

  • Unable to answer calls and messages
  • Unable to install the application
  • Lack of built-in GPS
  • Not compatible with iPhone


Unveiling of OpenAI new artificial intelligence capabilities





OpenAI claims that its free GPT-4o model can talk, laugh, sing, and see like a human. The company is also releasing a desktop version of ChatGPT’s large language model.

 Unveiling of OpenAI new artificial intelligence capabilities

Yesterday, OpenAI introduced the GPT-4o artificial intelligence model, which is a completely new model of the company’s artificial intelligence, which according to OpenAI is a step closer to a much more natural human-computer interaction.
This new model accepts any combination of text, audio, and image as input and can produce output in all three formats. It can also detect emotions, allow the user to interrupt it mid-speech, and respond almost as quickly as a human during a conversation.
In the live broadcast of the introduction of this new model, Meera Moratti, Chief Technology Officer of OpenAI, said: “The special thing about GPT-4o is that GPT-4 level intelligence has been made available to everyone, including our free users. This is the first time we’ve taken a big step forward in ease of use.
During the unveiling of the model, OpenAI demonstrated the GPT-4o, which translates live between English and Italian, with its intuitive ability to help a researcher solve a linear equation on paper in an instant, just by listening to The breaths of an OpenAI executive give him advice on deep breathing.
The letter “o” in the name of the GPT-4o model stands for the word “Omni”, which is a reference to the multifaceted capabilities of this model.
OpenAI said that GPT-4o is trained with text, images, and audio, meaning all input and output is processed by a neural network. This differs from the company’s previous models, including the GPT-3.5 and GPT-4, which allowed users to ask questions just by speaking, but then converted the speech to text. This would cause tone and emotion to be lost and interactions to slow down.
OpenAI will make this new model available for free to everyone, including ChatGPT users, over the next few weeks, and will also initially release a desktop version of ChatGPT for Apple computers (Mac) for users who have purchased a subscription, starting today. They will have access to it. The introduction of the new OpenAI model took place one day before the Google I/O event, which is the company’s annual developer conference.
It should be noted that shortly after OpenAI introduced GPT-4o, Google also presented a version of its artificial intelligence known as Gemini with similar capabilities.
While the GPT-4 model excelled at tasks related to image and text analysis, the GPT-4o model integrates speech processing and expands its range of capabilities.

Natural human-computer interaction

According to OpenAI, the GPT-4o model is a step towards a much more natural human-computer interaction that accepts any combination of text, audio, and image as input and produces any combination of text, audio and image.
This model can respond to voice inputs in less than 232 milliseconds, with an average speed of 320 milliseconds, which is similar to the response time of humans in a conversation.
This model matches the performance of the GPT-4 Turbo model on English text and code with a significant improvement in converting text to non-English languages while being much faster and 50% cheaper via application programming interface (API). The GPT-4o model is especially better in visual and audio understanding compared to existing models.

What exactly does the introduction of this model mean for users?

The GPT-4o model significantly enhances the experience of ChatGPT, OpenAI’s wildly popular AI chatbot. Users can now interact with ChatGPT like a personal assistant, ask it questions and even hang it up wherever they want.
Additionally, as mentioned, OpenAI is introducing a desktop version of ChatGPT along with a revamped user interface.
“We recognize the increasing complexity of these models, but our goal is to make the interaction experience more intuitive and seamless,” Moratti emphasized. We want users to focus on working with GPT instead of being distracted by the UI. Our new model can reason text, audio, and video in real-time. This model is versatile, fun to work with, and a step toward a much more natural form of human-computer interaction, and even human-computer-computer interaction.
The GPT-4o model has also been extensively reviewed by more than 70 experts in areas such as social psychology, bias and fairness, and misinformation to identify risks introduced or enhanced by the newly added methods. OpenAI has used these learnings to develop safety interventions to improve the safety of interacting with GPT-4o. The members of the OpenAI team demonstrated their audio skills during the public presentation of this new model. A researcher named Mark Chen emphasized its ability to gauge emotions and noted its adaptability to user interruptions.
Chen demonstrated the model’s versatility by requesting a bedtime story in a variety of tones, from dramatic to robotic, and even had it read to him. As mentioned, this new model is available for free to all ChatGPT users. Until now, GPT-4 class models were only available to people who paid a monthly subscription.
“This is important to us because we want to make great AI tools available to everyone,” said OpenAI CEO Sam Altman.

Strong market for generative artificial intelligence

OpenAI is leading the way in productive AI alongside Microsoft and Google, as companies across sectors rush to integrate AI-powered chatbots into their services to stay competitive.
For example, Anthropic, a competitor of OpenAI, recently unveiled its first corporate proposal to Apple to provide a free program for iPhones.
“We recognize that GPT-4o audio presentations present new risks,” OpenAI said in a statement. Today we’re publicly releasing text and image inputs and text outputs, and in the coming weeks and months, we’ll be working on the technical infrastructure, post-training usability, and security necessary to release other methods. For example, at startup, audio outputs are limited to a set of predefined sounds and adhere to our existing security policies. We will share more details about the full range of GPT-4o methods in a future system.
According to the report, the generative AI market saw a staggering $29.1 billion in investment across nearly 700 deals in 2023, up more than 260 percent from the previous year. Predictions indicate that the yield of this market will exceed one trillion dollars in the next decade. However, there are concerns about the rapid deployment of untested services by academics and ethicists who are troubled by the technology’s potential to perpetuate prejudice.
Since launching in November 2022, ChatGPT’s chatbot has broken records as the fastest-growing user base in history, with nearly 100 million weekly active users. OpenAI reports that more than 92% of the world’s top 500 companies use it.
At the presentation event last night, Moratti answered some questions from the audience and when he spoke in fluent Italian and the artificial intelligence translated his words into English, the hall was filled with excitement.
There is more. This means the next time you take a selfie, OpenAI’s artificial intelligence can assess your exact emotions. All you have to do is select a selfie and ask ChatGPT to tell you how you feel.
It should be said that OpenAI employees were so happy that ChatGPT asked them why they were so happy!
