On November 3, 2026, Samsung announced that its updated Sleep Apnea feature was available on Galaxy Ring and compatible Galaxy Watch devices. It screens for signs of moderate-to-severe sleep apnea; it does not diagnose the condition or replace care from a qualified clinician. Samsung’s announcement describes the feature as an on-demand tool for users 18 and older who have not previously been diagnosed with sleep apnea.

What it takes to get a screening result

Samsung requires two valid nights of data within a 10-day period. Its U.S. support guide says each night must include at least five hours of sleep, and that setup requires a compatible Samsung Galaxy phone running Android 12 or later. The feature is accessed through Samsung Health Monitor. Samsung’s U.S. setup guide also advises wearing the Galaxy Ring neither too tightly nor too loosely, with its orientation indicator toward the palm and its sensors against the skin.

The screening is on demand, not continuous: Samsung says monitoring ends when a result is ready or after 10 days, whichever comes first.

What a negative result means

A negative result does not rule out sleep apnea. Samsung says the feature can miss cases, and its U.S. guide advises contacting a health professional if symptoms continue, even when the feature detects no signs. The result also should not guide changes to medication.

Samsung’s U.S. guide cautions that pregnancy or temporary breathing problems, including flu, allergies or asthma, may affect accuracy. It lists certain movement-related, heart and lung conditions among reasons not to use the feature.

Regulatory milestones and Galaxy Watch support

Samsung says the original Sleep Apnea feature received U.S. FDA De Novo authorization in February 2024. The updated feature received U.S. FDA clearance in July 2026 and approval from South Korea’s Ministry of Food and Drug Safety in October 2026. Those are separate regulatory milestones for the original and updated features, respectively. Samsung’s announcement dates each one.

In that November 3 announcement, Samsung listed Galaxy Watch9 running Wear OS 7.0 or later and said Galaxy Watch7 and Galaxy Watch8 support would follow through software updates.
