Samsung’s Sleep Apnea feature supports Galaxy Watch4 series and later models, excluding Galaxy Fit, running Wear OS 5.0 or later, paired with a supported Android phone running Android 12 or later. To enable it, open Samsung Health Monitor on the paired phone, select the Sleep apnea tab, turn on the feature, and follow the prompts. You need about four hours of sleep on each of two nights within ten days; the result is not a diagnosis.
Availability depends on the market, device, and paired phone, so check Samsung Health Monitor and your local Samsung support information before buying a watch. Samsung reported availability in 70 markets on June 5, 2025; that is a dated snapshot, not a guarantee of current availability everywhere. [c003]

What the Galaxy Watch is measuring
Samsung describes the feature as analyzing relative decreases in blood oxygen associated with breathing disruptions during sleep. It is intended to detect signs of moderate-to-severe obstructive sleep apnea, not to provide a diagnosis. [c001] [c003]
The feature is an over-the-counter, software-only mobile medical application intended for on-demand use in adults aged 22 or older who have not already been diagnosed, over a two-night period. Samsung says its data is not intended to help clinicians diagnose sleep disorders. [c003] [c006]
What Sleep Apnea detection does not tell you
- It does not diagnose sleep apnea.
- It is not intended for someone who has already been diagnosed with sleep apnea. [c003] [c006]
- It does not replace traditional diagnostic methods, a qualified clinician, or prescribed treatment. [c003] [c006]
- A result should not be treated as proof that you have or do not have sleep apnea.
- Its data is not intended to help clinicians make a diagnosis. [c003]
What to do with the result
If the result or your symptoms concern you
Consult a qualified healthcare provider. Samsung advises users not to rely on the feature as a substitute for professional diagnosis or treatment. [c003] [c004]
If the result does not flag a concern
Do not treat that result as proof that sleep apnea is absent. Talk with a healthcare provider if you remain concerned or have symptoms.
