The Samsung Galaxy S5, S6 and S7 and Note line of phones have a lot of great features.
One of these, called “Safety Assistance,” is a built-in emergency tool that lets you quickly notify pre-determined contacts that you may be in immediate trouble.
You can enable and configure Safety Assistance by tapping Settings > Quick Settings > Safety Assistance > Send Help Messages.
Once the feature is turned on, you can send an SOS alert by pressing your phone’s lock button three times.
Sent information can include a map of your location, photos from your phone’s front and rear camera and a brief voice recording.
It’s important to note that Samsung’s Safety Assistance feature isn’t a means of contacting 911 (text-based 911 isn’t supported in all areas).
You should also be aware that poor network conditions may delay or block these alerts.
