I'll send an SOS to the world. I hope that someone gets my message in a bottle.

Since we're all pretty much tethered to a smartphone 24 hours a day, Samsung has designed some emergency functions, you know, just in case.

The Galaxy S7 comes with the ability to send SOS messages, enter emergency mode, and even receive Amber alerts.

How to enable SOS messages

Samsung introduced SOS messages on the Galaxy S6, a feature designed to literally be a lifesavers should the need for one ever arise.

Quickly tap your power button three times and the front and rear cameras will immediately take a photo and send them to your emergency contacts. It then sends a message to these contacts stating that you need help, along with your exact location and a 5-second ambient sound recording.

There's a bit of a setup process for this feature, so make sure everything is in order before heading out.

  1. Launch the Settings app from your Home screen or from the app drawer.
  2. Tap Privacy and safety.
  3. Tap Send SOS messages. It won't send a message right away; this is just to enable the feature.
  4. Tap the toggle to turn it on.

    Tap Privacy and safety, tap send SOS messages, tap the toggle to turn them on

  5. Tap the checkbox to agree to the terms and conditions.
  6. Tap Agree.
  7. Tap Add in the pop-up.

    Tap the checkbox, tap Agree, tap Add

  8. Tap Select from contacts to pick an existing contact; otherwise, tap Create contact.
  9. Tap the checkbox next to each contact to whom you'd like to send SOS messages, should you need to.
  10. Tap Done on the top right corner of the screen.

    Tap Select from contacts, tap the checkboxes to select contacts, tap Done

Now, the contacts you have selected will receive your SOS messages if you have to send them.

Remember: to send an SOS message, quickly press your power button three times.

How to use emergency mode on the Samsung Galaxy S7

Emergency mode is used in a situation where you absolutely need your phone to conserve as much power as possible while on standby. You may be out, lost in the wilderness, or you might be stuck somewhere and in need of a hand and that connection to the outside world.

Here's how to enable emergency mode on your Galaxy S7:

  1. Hold down your power button.
  2. Tap Emergency mode.
  3. Tap the checkbox to agree to the terms and conditions.
  4. Tap Agree.
  5. Tap Enable.

    Tap Emergency mode, tap Agree, tap Enable

Your phone will now flip to a grayscale display with only six available apps on the Home screen. The performance of the phone will be limited and you'll only be able to make emergency phone calls.

To disable emergency mode, you just have to tap More in the top right corner of the screen and tap Disable emergency mode.
