The S4 Light is Distracting
By default the Bluetooth indicator will flash blue at regular intervals to indicate that the S4 is switched on. If
you prefer, you can switch this light off. You might want to turn off the light if you find it distracting, for example
if you are using the S4 while driving at night.
When you turn the LEDs off, they will still light up when you turn the S4 on and off, but not at other times.
To turn the lights off or back on again, use the LED Light command.
