The Galaxy Fit 3 arrived in early 2024, so a successor is overdue — and it looks like Samsung is finally getting ready. Renders of the Galaxy Fit 4 have surfaced from an update to Samsung’s own app, and regulatory filings for model SM-R391 suggest a launch is not far away.
Key Takeaways
- Galaxy Fit 4 renders leaked from Samsung’s own app update.
- It appears in three colors, with a familiar slim fitness-band design.
- Bluetooth 5.4 is expected, up from Bluetooth 5.3 on the Fit 3.
- A new Goodix GH3036 sensor is reportedly inside.
- GPS remains unconfirmed — the biggest open question about the Fit 4.
What the Renders Show
The renders show a device that is instantly recognizable as a Galaxy Fit. The slim rectangular body, the wraparound strap, and the clean watch face all carry over from the Fit 3, which makes sense: the Fit line has always been about disappearing on your wrist, not making a fashion statement. A 1.6-inch AMOLED display is expected again, keeping the band light, readable, and easy to wear all day.
Look closer, though, and the details change. The watch face in the renders matches the strap color, giving the Fit 4 a more coordinated look, and the sensor array on the back points to new hardware inside — reportedly a Goodix GH3036 sensor, which should bring improved heart-rate and sleep tracking over the Fit 3.

The GPS Question
The Fit 3’s biggest weakness was its lack of built-in GPS: runners had to carry their phone to track routes accurately. The Fit 4 leaks so far say nothing about GPS, which is why this is the question to watch. If Samsung adds it, the Fit 4 becomes a far more serious running companion; if not, it remains a great everyday tracker that still leans on your phone for route mapping.
Price and Launch Expectations
Certification filings point to a launch soon. The Fit 4 has appeared in FCC filings, Malaysia’s SIRIM database on October 16, and India’s BIS system — a pattern that usually precedes a release by weeks rather than months. Pricing is expected to stay close to the Fit 3, at around $60, which would keep it one of the best-value fitness bands Samsung sells.
FAQs
When will the Galaxy Fit 4 launch?
Samsung has not announced a date, but FCC, SIRIM, and BIS filings suggest a launch is near.
What colors will the Galaxy Fit 4 come in?
Leaked renders show three colors, though Samsung has not yet confirmed their names.
Does the Galaxy Fit 4 have GPS?
That is still unconfirmed. The Fit 3 had no built-in GPS, and the leaks so far do not settle the question for the Fit 4.
What is new in the Galaxy Fit 4?
Expected upgrades include Bluetooth 5.4, a new Goodix GH3036 sensor, and refreshed colors, with a similar 1.6-inch AMOLED display.
How much will the Galaxy Fit 4 cost?
Pricing is not confirmed, but around $60 is expected, in line with the Galaxy Fit 3.
Bottom Line
The Galaxy Fit 4 looks like a careful, sensible update: the same slim, comfortable design, a newer sensor, and modern Bluetooth — all at a price that should stay very affordable. Whether it finally answers the GPS question will decide if it is a modest refresh or a genuinely bigger upgrade for runners. Either way, it is shaping up to be one of the easiest fitness bands to recommend.
