Samsung Galaxy Fit 4 Leaks with RTOS and Larger OLED Screen

The Samsung Galaxy Fit 4 has surfaced in leaked design renders, revealing a refreshed budget fitness tracker available in black, white, and green colorways. The most notable upgrade is an expanded rectangular OLED display housed in a metallic silver frame, offering more screen real estate than the Galaxy Fit 3. Tailored for casual fitness enthusiasts who prioritize long battery life and essential health tracking, the wearable trades Google Wear OS for a lightweight RTOS, and users will likely still need a paired smartphone for outdoor route tracking due to the probable absence of built-in GPS.

Refreshed Design and a Bigger Screen

Leaked renders shared by The Cipher Project show that the upcoming fitness band retains the sleek, minimalist aesthetic established by its predecessors. The rectangular OLED screen appears visibly wider and taller than the display on the Galaxy Fit 3, giving users extra space to view daily activity statistics, incoming notifications, and workout metrics without excessive scrolling.

Surrounding the expanded display is a silver-toned bezel that lends the tracker a more metallic, premium appearance compared to earlier models. On the right side of the casing, Samsung retains a single physical hardware button, which serves as a dedicated trigger for waking the display and navigating back through menus.

Core Tracking Hardware and RTOS Efficiency

Under the hood, earlier hardware disclosures indicate that the Galaxy Fit 4 will support Bluetooth 5.4 with EDR for faster and more stable pairing. The rear casing houses an optical heart rate sensor dedicated to continuous pulse monitoring, sleep tracking, and basic exercise logging.

Because the device is positioned as an entry-level fitness tracker, it will not run Google Wear OS. Instead, Samsung relies on an efficient Real-Time Operating System (RTOS) to minimize manufacturing costs and keep power consumption low. The trade-off is a locked ecosystem without downloadable third-party apps.

It remains unconfirmed whether the Galaxy Fit 4 integrates standalone GPS hardware. If satellite positioning is omitted, runners and cyclists will need to bring their smartphone along to map outdoor routes and record precise pacing data.

Would the lack of built-in GPS be a dealbreaker for your daily workouts, or do you prefer the lighter weight and extended battery life of an RTOS-based tracker?
