This Samsung Galaxy Fit3 review covers the Silver SM-R390 fitness band. It combines a 1.6-inch AMOLED display, exercise tracking, sleep insights and phone notifications in a compact aluminium body. Its strongest fit is everyday tracking alongside a compatible Android phone, particularly a Samsung Galaxy smartphone.
Our verdict: choose the Galaxy Fit3 if you want a clear screen, a straightforward activity record and Samsung Health integration. Check phone compatibility first: it does not support iPhone pairing. Runners who want GPS route recording without carrying a phone should look at a watch with built-in GPS.

1. Phone compatibility comes before the feature list
The Galaxy Fit3 works with Android phones. Samsung’s India documentation specifies a Galaxy smartphone with Android 10 or later and at least 1.5 GB memory for several features. Other Android users should confirm support for their exact phone and the features they need. iPhone, Galaxy Tab and Galaxy Book pairing are not supported.
Set up the band through Galaxy Wearable and review your activity data in Samsung Health. Complete the account, permission and notification settings during initial setup. For a shared family purchase or gift, check the recipient’s phone rather than assuming a Bluetooth connection alone establishes compatibility.
2. The AMOLED screen suits quick daily checks
The rectangular AMOLED display gives activity figures and notifications more space than a narrow tracker screen. A side button provides a quick route back to the main screen. The Silver version pairs its metal body with a light-coloured band, giving it a simple everyday appearance.
Its practical appeal is easy access to a few useful numbers: the time, steps, workout information or an incoming alert. Consider how the band fits your wrist and whether the display is easy for you to read. A device that you comfortably wear through the day and night is more useful than one whose features you rarely open.
3. Exercise tracking covers everyday sessions
Galaxy Fit3 provides more than 100 exercise options and can automatically recognise selected activities when auto detection is enabled. Start a workout manually when recording the exact beginning and end matters. Review automatic entries afterwards to keep your activity history understandable.
Outdoor GPS recording depends on the paired phone. Bring a compatible Galaxy smartphone when you want its location data for a supported workout. This makes the Fit3 a reasonable match for someone who already carries a phone on walks and runs. For phone-free GPS recording and more training analysis, our Garmin Forerunner 265 review covers a different type of sports watch.
4. Sleep and wellness information are most useful over time
Samsung Health brings together sleep records, activity and wellness information. The Fit3 offers sleep-stage estimates, sleep scores and coaching, alongside heart-rate, stress and blood-oxygen features. Samsung specifies at least seven days of sleep data, including two days off, for Sleep Coaching.
Snoring detection uses the microphone on a nearby paired Galaxy phone; the band does not make that feature independent of the handset. Use sleep records to explore your routine and compare several nights. Heart-rate, oxygen and sleep figures are wellness information rather than medical diagnoses. The Fit3 also does not provide ECG or body composition measurements.
5. Battery life and water resistance need the correct figures
Samsung advertises up to 13 days from the 208 mAh battery. That is a test-based maximum, and your display settings, notifications, workouts and measurement settings affect the result. Samsung also advertises charging to approximately 65% in 30 minutes under its test conditions.
The 5 ATM and IP68 ratings cover defined water and dust tests. They do not make the band suitable for diving or high-pressure water activities. Follow the manual’s swimming and care instructions, and dry the band and charging contacts before charging. Treat the marketplace’s contradictory “not water resistant” field as an error, rather than overlooking Samsung’s published rating.
6. Phone controls add convenience without replacing the handset
You can check notifications, use preset text replies where supported and control media playing on the phone. Find My Phone helps ring a connected handset within Bluetooth range. Camera Remote is available with compatible Galaxy smartphones running One UI 6.0 or later and the supported Samsung camera mode.
These features are useful when the phone is nearby but inconvenient to reach, such as during a workout or while taking a group photograph. Media control is different from downloading a music library to the band. The Fit3 is also a Bluetooth fitness band rather than a standalone LTE calling watch, despite the cellular wording in some marketplace fields.
7. Set up fall detection and SOS deliberately
The Galaxy Fit3 includes hard-fall detection and Emergency SOS options. Samsung describes pressing the Home button five times to trigger the SOS process. Use Galaxy Wearable’s Safety and emergency settings to configure contacts, emergency options and medical information before relying on them.
Emergency communication requires the compatible connected phone and appropriate connectivity. Fall detection cannot guarantee that every fall will be recognised, so it should support an existing plan for getting help. It is a useful extra for a fitness band, but it does not turn the Fit3 into an independent emergency communicator.
Strengths and trade-offs
| Reasons to consider it | Buying limitations |
|---|---|
| Large AMOLED display in a compact band format | Phone and feature compatibility need checking before purchase |
| Activity, sleep and wellness information in Samsung Health | No iPhone pairing, ECG or body composition measurement |
| Up to 13 days of advertised battery life | Actual endurance varies with settings and use |
| Fall detection, SOS setup and phone controls | Phone connectivity is required for communication features |
| Many workout options and selected automatic detection | No built-in GPS for independent route recording |
Samsung Galaxy Fit3 review: final buying verdict
The Galaxy Fit3 is a sensible everyday tracker for a compatible Android user who values a clear display and Samsung Health. Choose it for regular activity recording, sleep patterns and convenient phone alerts. Check that the features you want work with your exact phone, especially if it is not a Samsung Galaxy model.
Before ordering the Silver SM-R390, confirm the seller, regional warranty, box contents and return terms. Compare the current offer with our Fitbit Inspire 3 review if you are considering another fitness band. Your phone compatibility and tracking routine matter more than a long list of marketplace specifications.
