3. Select Sleep → Snore detection.
4. Toggle the switch to enable snore detection.

5. Why Sleep Data May Be Inaccurate

Several factors can affect the accuracy of sleep tracking:

- Loose wristband placement can reduce motion and heart rate accuracy.

6. Additional Tips for Accurate Sleep Tracking

Follow these recommendations for reliable sleep data:

- Wear the Galaxy Fit3 firmly on your lower arm, just above the wrist.
