Flashing light
An ordinary flashlight is built into any modern smart phone. However, if you think that they can only shine in the dark, you are mistaken.
In an extreme situation, it is a real wand.

Tip: if you suddenly had a disaster, and you urgently need help to get the attention of rescuers or who will help you out, you can give three light signals: 3 short, 3 long and 3 short again.
Thus, you are giving the famous SOS signal - an international distress signal. You will surely be heard and helped in an emergency.
