Samsung Galaxy Fit 4 Leaks in Three Colours With Bluetooth 5.4: Looks Like the Fit 3

Samsung looks set to launch a new budget fitness band, the Galaxy Fit 4. Leaked images and videos have now shown the full design in three colours, and it looks a lot like last year's Galaxy Fit 3. Samsung has not announced the band, so everything below comes from leaks and filings.

Design: a familiar look

The leaked renders show a long, rectangular screen with rounded corners, a single physical button on the right side and a plain silicone strap. That is the same layout as the Galaxy Fit 3, so this looks like a tidy update rather than a redesign. The bezel around the screen appears to be silver. The back has a heart-rate sensor in the middle with the charging contacts next to it.

One report says the screen looks bigger than the one on the Galaxy Fit 3, which has a 1.6-inch AMOLED display. Another says the images do not show whether Samsung changed the size. Treat the screen size as unknown for now.

Colours

The band appears in three colours: black, white and a third shade. One report calls the third colour green, while another describes it as light blue, so the exact shade is not clear. The images come from a messaging channel and not from Samsung.

What the filings say

The band carries the model number SM-R391 and is listed as "FIT4" in a US regulatory filing that appeared in August. The paperwork shows Samsung was already testing hardware in July. Regulatory documents also point to Bluetooth 5.4, an upgrade from Bluetooth 5.3 on the Galaxy Fit 3. The same filing lists a battery supplier but does not give the capacity.

A heart-rate sensor from Goodix, the GH3036, is also possible, but that has not been confirmed. Nothing is known yet about extra health sensors.

What we still do not know

Battery life is the big open question. One report expects at least a week on a single charge, and that is a guess based on the Galaxy Fit 3. It is also not clear whether the Galaxy Fit 4 gets its own GPS, which the Galaxy Fit 3 does not have, or NFC for payments. The band is also reported to run a simple operating system rather than Wear OS, which would keep the cost down, but that is not confirmed either.

What we know at a glance

Price and launch date

Samsung has not announced a price, a launch date or the countries where the band will be sold, including India. Because the Galaxy Fit line is Samsung's cheapest wearable, expect the Galaxy Fit 4 to be priced below its Galaxy Watch models. We will update this article when Samsung confirms the details.
