Howdy BLR, thanks for taking the opportunity to inquire about the Samsung Galaxy Watch8. To enable the fall detection feature on your Galaxy Watch8, please open the Galaxy Wearable app on your phone, then go to Watch settings, and tap Safety and emergency, then select Hard fall detection, and finally be sure to toggle the switch to turn it on. Take a moment to check out, "Use the Detect fall feature on your Samsung smart watch" if you would like to learn more about using this feature. Let us know if you would like further assistance by reaching out to Support at your leisure. Thank you for being a valued Samsung customer. - Debra
