■ Showing a wave message in the air
To show the message, turn the back side of the phone towards the person to
whom you want to show it, and wave the phone in the air evenly. The LEDs in the
back cover paint the message in the air. The LEDs work best in the dark or with a
dark background behind you, and the optimal viewing distance is from 1 to 6
metres.
If the message does not appear in the air, try to wave the phone faster from one
side to another. To discover the optimal waving speed and position, you can
practice waving your phone, for example, in front of a mirror.
