The Quick button gets positive marks for usefulness and shortcut flexibility, but other reviews dislike the overall button layout or want better workout-time control behavior.
Multiple reviews explicitly note that the Pace 4 has no speaker and is not built for handling calls.
Reviews confirm that the watch supports speaker-and-mic calling, but they focus more on availability and setup than on deep call-quality analysis.
The watch tracks active calories alongside steps and floors, giving basic daily calorie data rather than especially deep calorie guidance.
Charging is generally convenient thanks to the compact adapter and keyring approach, though reviewers do not describe it as a fast-charging standout.
Wireless charging is a plus, but convenience is undercut by Samsung’s decision to omit the wall charging block in the box.
Charging looks decent rather than class-leading, with one review citing about 95 minutes for a full charge and another showing a meaningful top-up during a short morning routine.
