Symptoms

  • Watch triggers an emergency call after a hard high-five, sport, or drop of the arm
  • Alert countdown starts even when you're fine
  • False alarms happen mostly during specific activities like tennis or biking
  • Emergency contacts get notified unnecessarily

Likely causes

  • CommonHigh-impact wrist motion mimicking a fall patternThe accelerometer can misread sudden, hard arm movements from sports.
  • PossibleFall detection sensitivity too high for your activity levelSome watches let you tune or disable this per activity type.
  • PossibleWatch not set to the correct activity mode during exerciseCertain sport modes suppress fall detection intentionally.

What to do

  1. When a false alert triggers, tap 'I'm OK' or cancel promptly before the countdown finishes, so no emergency call goes out.
  2. Check the watch's fall detection settings and consider turning it off during specific high-impact sports.
  3. Select the correct workout or activity mode before playing sports, since many suppress false fall triggers automatically.
  4. Update the watch's firmware, since fall detection algorithms are periodically refined.
  5. If false alarms are frequent and disruptive, weigh disabling the feature entirely against its safety benefit for you.

When to call a pro

No professional help is needed; this is a settings adjustment based on your activity patterns.
