SOS is an international distress signal that flashes in the pattern '···−−−···' (three short, three long, and three short). You can use it to signal for help in an emergency.
Red light helps preserve your eyes' dark adaptation. Using it for stargazing or nighttime reading reduces the time your eyes need to readjust when you move from a bright area to a dark one.
Keeping the screen bright can drain the battery faster than normal use. If you use it for a long time, we recommend keeping your device plugged in.
