Samsung appears to be preparing the Galaxy Fit 4, a possible successor to the Galaxy Fit 3 launched globally in 2024. The new fitness tracker is expected to compete with devices such as the Fitbit Edge, but Samsung has not confirmed its release date or specifications.
The Galaxy Fit 3 launched at $59 and later became available in the U.S. during winter 2025. No pricing information has surfaced for the Galaxy Fit 4, although expectations point to a slightly higher price than its predecessor while remaining below the $99 Fitbit Air.
Leaked blueprints reportedly show a rectangular device with an AMOLED touchscreen and one physical button on the side. This would preserve the basic design used by the Galaxy Fit 3. The previous model has a 1.6-inch display with 256 x 402 resolution and brightness of around 600 nits.
A report from SammyGuru, said to be based on an unreleased version of Samsung’s companion app, indicates that the Galaxy Fit 4 could use a 258 x 428-pixel panel. The screen size is expected to remain similar, while a brighter display is considered possible. The wearable may use an aluminum case and arrive in at least three colors, potentially including black and white, alongside blue or green options.
Samsung documents reportedly identify the company’s GH3036 health sensor array for the device. This could support continuous heart-rate monitoring and other health measurements. Recent insider reports have also pointed to stress-management tools and automatic workout detection.
Other expected features include fall detection, emergency SOS, blood oxygen readings, sleep scores, high- and low-heart-rate notifications, and snore detection. Sleep apnea detection is another potential addition, although it has not been confirmed.
GPS and NFC remain among the biggest unanswered questions. The Galaxy Fit 3 lacks both features, so their inclusion would allow phone-free location tracking and contactless payments. However, GPS could affect battery life. The previous tracker can last up to 13 days per charge, and similar endurance is expected unless the new model includes a more power-hungry GPS system.
Compatibility could also influence the Galaxy Fit 4’s success. The Galaxy Fit 3 does not support iOS, while Fitbit’s trackers work with both Android and Apple devices. Even with hardware upgrades or an aggressive price, limited platform support could make the Galaxy Fit 4 less appealing to users outside Samsung’s ecosystem.
