Samsung Galaxy Fit 4 leaks: familiar design, Bluetooth 5.4 upgrade

Leaked footage and a string of regulatory filings have given the clearest look yet at Samsung's next budget fitness tracker, and the picture is almost identical to the device it replaces. The Samsung Galaxy Fit 4 leaks published this week show a band that looks nearly indistinguishable from the Galaxy Fit 3, with Bluetooth 5.4 standing out as the only confirmed specification change reported so far (SammyGuru, three weeks ago).

The footage shows the band in black, white, and a third light shade that two outlets describe differently, traced to leakers on Telegram rather than anything Samsung has published officially (Android Headlines; SamMobile). Samsung has not announced the Galaxy Fit 4, confirmed a release date, or said whether it will sell in the U.S., where the Galaxy Fit 3 never launched (Android Headlines).

Current Fit 3 owners have no documented reason to upgrade yet. Prospective buyers should hold off on assuming this is a meaningful successor rather than a connectivity refresh until Samsung confirms price, launch markets, battery life, and whether health tracking actually changes.

What Samsung Galaxy Fit 4 leaks and filings actually show

Two different kinds of evidence are driving this story, and they don't carry equal weight. Regulatory filings with the FCC, India's BIS, and the Bluetooth SIG have repeatedly surfaced a device carrying model number SM-R391, labeled "FIT4" in some documents, with an optical heart-rate sensor, pogo-pin charging contacts, and a quick-release strap mechanism on the back (SammyGuru, three weeks ago; SamMobile, in August). That's documented hardware, not guesswork, since the same model number keeps resurfacing across independent certification databases.

Leak footage fills in the rest: a rounded rectangular display with a silver bezel, a physical button on the right edge, a silicone strap with adjustment holes, and the three colorways now making the rounds. That footage traces back to a Telegram channel called The Cipher Project, not to Samsung itself, so it's useful for visual reference but not an official confirmation of anything (SamMobile; Android Headlines).

Android Headlines reached a similar conclusion after its own look at the device, describing the Fit 4 as looking very similar to its predecessor. That lines up with what the certification filings already suggested: a rectangular body, a side button, and sensors on the back arranged roughly the way Galaxy wearable owners already know (Android Headlines).

Samsung Galaxy Fit 4 colors: three shades, one unresolved detail

Both leaks agree the Galaxy Fit 4 will come in three colors: black, white, and a third, lighter option. Where they disagree is what that third color actually is. SamMobile, citing images posted to the Telegram channel The Cipher Project, calls it green and says the device appears to have a bigger screen than the Fit 3's (SamMobile).

Android Headlines describes the same shade as "very light blue" and doesn't mention any difference in screen size at all (Android Headlines). Neither outlet has published measurements, so there's no way to settle which account is right, or whether both leakers are simply describing the same pale shade under different lighting. Treat the exact color name and any screen-size claims as pending until Samsung does its own reveal.

What's confirmed, and what's still rumor

Bluetooth 5.4 with Low Energy and Enhanced Data Rate support is the one spec change that multiple independent filings back up, replacing the Bluetooth 5.3 radio in the Galaxy Fit 3 (SammyGuru, three weeks ago; SamMobile, in August). That makes it the only reported functional upgrade over the previous model, not the only documented detail about the Fit 4 overall; the heart-rate sensor, charging contacts, and strap hardware mentioned above are confirmed too, they just aren't new relative to the Fit 3.

Don't expect the Bluetooth bump to change daily use much. SammyGuru, which has tracked the Fit 4 through its certification filings, notes the upgrade "may not make a major difference in everyday use" even though it should improve wireless efficiency and compatibility with newer phones (SammyGuru, three weeks ago). It's a backend improvement, not something you'll notice on the wrist.

Everything else tied to the Fit 4 carries more hedging. Gizmodo reported in August that documentation pointed to a Goodix GH3036 optical sensor module, which could mean health-tracking features similar to the Galaxy Fit 3's, though that's a possibility raised by leaked documents, not a confirmed spec (Gizmodo, in August). SamMobile separately reports the Fit 4 will likely run a lightweight RTOS instead of Wear OS to cut costs, and could offer at least a week of battery life on a charge, language that stays firmly in "likely" and "could" territory (SamMobile).

Built-in GPS would make the Fit 4 more useful without a phone nearby, but SammyGuru points out there's no confirmation Samsung is adding it, and Gizmodo similarly flags NFC support as unconfirmed rather than a settled feature (SammyGuru, three weeks ago; Gizmodo, in August). Samsung hasn't confirmed any of this, and no outlet has run independent hands-on testing to verify sensor accuracy, software behavior, or real-world battery drain.

Samsung Galaxy Fit 4 vs Galaxy Fit 3: what buyers should weigh

The Galaxy Fit 3 is the baseline for judging whether the Fit 4 is worth the wait. It launched in early 2024 at roughly $60, sold mainly across Asia, Europe, and Latin America, and never reached U.S. shelves (Android Headlines). Two years is a long gap for a budget wearable line, which is part of why the SM-R391 filings have drawn attention: the device is clearly moving through certification, but none of those filings say anything about a launch date or confirm whether the Fit 4 will finally sell in the U.S. (SammyGuru, three weeks ago).

Price comparisons to Google's Fitbit lineup are worth noting, but only as a conditional reference point. Android Headlines pegs the Fitbit Edge at $179; if Samsung repeats the Fit 3's roughly $60 launch price, the Fit 4 would undercut it by a wide margin. That gap only matters if Samsung actually prices the Fit 4 that low and sells it in the same markets as Fitbit, neither of which Samsung has confirmed. Android Headlines frames the device as a potential answer to the Fitbit Edge specifically, but stops short of calling that a confirmed strategy rather than a plausible read on the timing (Android Headlines).

A handful of questions still separate this from a real buying decision. Launch regions, especially whether the Fit 4 breaks the Fit 3's U.S. absence, top the list, followed by final pricing, verified battery life, whether GPS or NFC get added this generation, and whether health tracking meaningfully improves over the Fit 3 rather than just carrying the same feature set forward (SammyGuru, three weeks ago; Gizmodo, in August).

What to check before Samsung's announcement

Right now, the verified facts are narrow: a design that looks nearly identical to the Galaxy Fit 3, three leaked colorways with one shade still disputed between leakers, and Bluetooth 5.4 as the only confirmed spec upgrade. Everything tied to battery life, sensors, operating system, and pricing remains either hedged reporting or outright speculation.

Before deciding anything, watch for Samsung's official announcement to confirm display size and sensor hardware, check whether a U.S. listing actually appears this time, and compare any announced price against the Fit 3's roughly $60 launch point. Wait for an independently tested battery figure rather than the "at least a week" estimate currently circulating, and look for Samsung to state plainly whether GPS and NFC made the cut.

Nothing in the current evidence shows the Fit 4 as more than a connectivity-focused refresh of its predecessor. Hold off on purchase plans until Samsung's own reveal and independent hands-on reviews fill in the gaps the leaks haven't.
