Hello there Amy, thank you for your question about the Samsung Galaxy Watch7. Yes, the Galaxy Watch7 detects snoring by using the microphone on your paired smartphone to record audio while you sleep. You must enable the feature in the Samsung Health app, wear the watch to bed, and keep your charging phone nearby to monitor, detect, and optionally record snoring sounds. If you think of additional questions, do not hesitate to reach out to Support. Thank you for being a loyal Samsung customer. - Debra
