Leaked footage and multiple regulatory filings have revealed the design and several specifications for the Samsung Galaxy Fit 4, a successor to the Galaxy Fit 3 that may be headed to India. The device has been identified under model number SM-R391 in documents from the FCC, Bluetooth SIG and India’s BIS, and the earliest visual leaks show the tracker in three colour options: Black, White and Light Blue. None of the details have been confirmed by Samsung.
What the leaks show
The leaked video, circulated on Telegram according to reports, presents the Galaxy Fit 4 with an exterior very similar to the Galaxy Fit 3: a pill-shaped optical sensor on the rear and metal charging contacts that indicate a pogo-pin charging arrangement rather than USB-C charging. The regulatory listings linked to the device also point to connectivity and sensor features.
- Colours: Black, White, Light Blue (reports note early variance in how the third colour was described)
- Model number: SM-R391
- Sensors: pill-shaped optical heart-rate sensor (as on previous model)
- Charging: pogo-pin contacts visible in renders and footage
- Connectivity: Bluetooth 5.4 (Low Energy and Enhanced Data Rate support tipped)
The move from Bluetooth 5.3 on the Galaxy Fit 3 to Bluetooth 5.4 on the Fit 4 is highlighted in the leaks. Industry listings suggest the newer radio protocol could bring incremental improvements in wireless efficiency and device compatibility with modern smartphones, but those benefits will depend on implementation and receive-side support from phone makers and platforms.
Specifications at a glance
| Item | Leaked detail |
|---|---|
| Model number | SM-R391 |
| Colours | Black, White, Light Blue |
| Sensors | Optical heart-rate sensor (pill-shaped) |
| Charging | Pogo-pin contacts |
| Connectivity | Bluetooth 5.4 (LE + EDR) — tipped |
Regulatory appearances in the FCC and Bluetooth SIG typically precede official launches, and an India BIS entry makes the Fit 4 a strong candidate for an Indian release. However, the leaks do not include final pricing, launch dates, battery capacity, display or confirmed fitness-tracking features beyond the optical heart-rate sensor. Samsung has not issued a statement confirming the model or its specifications.
For Indian readers, the presence of a BIS listing is notable because it suggests Samsung or its partners have at least begun the certification process required to sell the device in India. The exact timing of any launch, retail availability, market-specific features or India pricing will depend on Samsung’s official announcement.
The information summarised here is drawn from leaked footage and regulatory filings; these items are unconfirmed until Samsung provides official specifications and launch details.
