Samsung Galaxy Fit 4 recently appeared in a US Federal Communications Commission certification listing. This development suggests that its launch may arrive soon. Meanwhile, Samsung appears to be developing another wearable. References to the new device have reportedly appeared in the Samsung Wearable app.
The upcoming model is expected to sit between the Galaxy Fit 4 and the Galaxy Watch FE. It could help Samsung fill the gap in its wearable range between fitness bands and higher-end smartwatches.
According to reports, Samsung is working on a wearable with the internal codename Galaxy Aero. The Galaxy Wearable app identifies it as “galaxy_rtos_watch.” Unlike Wear OS models, this device is expected to run on a real-time operating system. Such systems are commonly used in more affordable wearables.
If launched, the Galaxy Aero will likely position itself between the Galaxy Fit 4 and Galaxy Watch FE. It is expected to include an accelerometer, gyroscope, and heart rate monitor. Moreover, the device should offer longer battery life than typical Wear OS watches.
Samsung has not released a new fitness tracker since the Galaxy Fit 3 in 2024. The Galaxy Fit 4 now appears close to announcement. It was spotted in the FCC database under the model number SM-R391. The filing confirmed support for Bluetooth Low Energy.
The Fit 4 is believed to use a Goodix GH3036 sensor module for heart rate monitoring and sleep tracking. It may also include a photoplethysmography sensor.
For reference, the Galaxy Fit 3 launched in India in February 2024 at a starting price of Rs. 4,999. It featured a 1.6-inch display, 16MB of RAM, and 256MB of storage. The tracker offered more than 100 watch faces and carried an IP68 rating. Sensors tracked heart rate, stress levels, and blood oxygen levels.
These developments indicate that Samsung is expanding its wearable options across different price and feature levels.
