There could be something new coming from Samsung in terms of fitness tracker products, but their latest wearable device has already generated some interest. Samsung’s upcoming Galaxy Fit 4 was leaked in a video clip and despite the fact that the design is somewhat similar to what we have seen before, there might still be some surprises in this one. After all, a new fitness tracker does not necessarily need a totally new design.

This is just a sneak peek into what Samsung could be planning, but the more interesting thing would be whether Samsung would be able to add something new and different or would strictly follow the path which was responsible for the success of its previous model. Let us find out from the details of this leak what Samsung may have planned.
Samsung Galaxy Fit 4 Leaks in Three Colors
Leaks happen to be the most reliable source when it comes to breaking any tech-related news. In this case, we got an excellent sneak peek from the leak as Android Authority managed to get its hands on exclusive video snippets and render leaks of what is said to be Samsung’s Galaxy Fit 4. With these leaked renders, we can take a great look around the upcoming wearables. As per these leaked videos, Samsung Galaxy Fit 4 will come in three different colors. These reported colors include a classic black, a clean white and a very light blue finish.
The light blue model is especially noticeable due to the elegant way it adds some style to this smartwatch. However, it is important to note that these renders are still leaks. Samsung has not yet officially approved the product, its colors or its release date. So, we should certainly not refer to them as official Samsung product renders. Additionally, it is impossible to say whether all three colors are approved until Samsung officially announces something. Nevertheless, even without such an approval, the leak gives us a quite definite idea of how the Samsung Galaxy Fit 4 would look. Strangely enough, it is extremely similar to the previous model, Galaxy Fit 3.

Galaxy Fit 4 Design: What’s Changed From the Fit 3?

When you put the leaked photos of the Samsung Galaxy Fit 4 next to its predecessor, it may be difficult to differentiate between the two. As seen from the leaked photos, the device comes with a recognizable rectangular-shaped screen with round edges. The long screen is enclosed by a casing that features rounded edges. Together with the screen, the Samsung Galaxy Fit 4 comes with the familiar side button on the right side of the fitness band.
Additionally, the new model appears to feature a regular silicone band. It comes with many adjusting slots and a regular buckle which helps make the device suitable for wearing comfortably. As for the rear part of the device, the arrangements of the sensors on it is surprisingly similar to that of previous models. Generally speaking the dimensions and design of the Samsung Galaxy Fit 4 fitness tracker are virtually the same as those of its predecessor, Galaxy Fit 3.
The latest leak doesn’t give us any indication of any big changes made to the screen size or to the outer body design. It’s necessary to state that just because the device looks the same doesn’t mean the internal specifications haven’t been changed. The biggest changes by Samsung could have been done internally.
Galaxy Fit 4 Specifications: What We Know So Far
Though the entire specification sheet is yet unavailable for official references, recent leaks give us insight into the hardware of the upcoming Samsung Galaxy Fit 4. As per earlier reports by the tech publication Android Authority, the coming wearable device has been linked with the SM-R391 model number. The particular model number has been seen to be explicitly tied to the FIT4 model name in different regulatory applications. Besides the above-mentioned model number, there are reports of the new device having Bluetooth 5.4 support. It is therefore expected to be more efficient than previous standards.
Moreover, the leaked documents show that there is a particular optical sensor module intended to serve as a daily health monitor. The reports clearly indicate that Samsung Galaxy Fit 4 may use the Goodix GH3036 sensor, which is especially built to be used with low power for heart rate measurement and fitness tracking. As the hardware is specifically developed to be energy-efficient, the software is going to mirror this approach. Thus, it is unlikely that the operating system will be based on heavy platforms such as Wear OS. In the end, although these leaks describe an energy-efficient fitness tracker, all the specs still need to be verified by Samsung.
Galaxy Fit 4 vs Galaxy Fit 3: Should You Expect a Major Upgrade?
It is important to take a closer look at the previous product in order to see how the Samsung Galaxy Fit 4 stands out in the market. The Galaxy Fit 3 came out in February 2024. This device has become very popular because of its small size, vivid AMOLED screen and dependable fitness tracking during daily activities. That is why users are expecting great improvements from the new model.
Given the Samsung Galaxy Fit 4’s limited visible design changes, the exterior will not be the main selling point. Instead, the true value of the upgrade will depend entirely on what is hidden inside the casing. Features like battery life, advanced health sensors, built-in GPS capabilities and software fluidity will matter far more than just new color options.
Right now, we should avoid making any bold claims. We cannot definitively state that the Samsung Galaxy Fit 4 has improved health tracking, built-in GPS or a significantly larger battery. Until reliable evidence confirms those specific details, we must temper our expectations. If you are currently exploring Samsung wearable alternatives, you already know that Samsung usually reserves its biggest hardware leaps for its premium tier, like Samsung Galaxy Watch 9 alternatives seen in recent Galaxy Watch releases.
What Samsung Still Needs to Confirm
While the Android Authority provides us with an excellent visual look, there are still many questions that are yet to be answered. First and foremost, Samsung should clarify the technical specifications of the display and the actual size of the casing. In addition to that, the battery life and endurance of the device are still unknown.
The battery life of the fitness trackers is usually a decisive criterion for people who search for such devices at an affordable price. Next, one should be clarified if there will be the built-in GPS in the device this time. Lastly, there are a number of other questions that should be answered directly by Samsung, the health sensors, the list of tracking functions, the actual price and the release date of the Samsung Galaxy Fit 4.
Wrap Up
The Samsung Galaxy Fit 4 might seem familiar, but that is not all there is to it. The footage that has been leaked gave us a glimpse of the product, but some crucial information remains unknown. Now, it is a matter of waiting to find out whether Samsung plans to unveil something more exciting than new colors.
