Greetings, thank you for finding the time out of your bustling day to ask us your question about the Samsung Galaxy Watch8. Yes, the advertised Galaxy Watch8 utilizes sensors to detect significant changes in motion patterns indicative of a fall. When a hard fall is detected, the watch will alert you with vibrations and a sound for 60 seconds, giving you the option to cancel the active alert or send an SOS message to your emergency contacts. If no response is received within that 60-seconds, the watch will automatically send an SOS message with your location to pre-set emergency contacts and can also initiate a call to them. If you have additional questions for us, feel free to reach out to Support. Thank you for being a dedicated Samsung customer. - Debra
