Setting the Breathing Light 
The breathing light on the back of your phone will be turned on

call or an app notification. You can also assign a specific 
breathing light colour to a contact or an app, so you know who is 
calling or which app has a notification when you see the 
breathing light. 
  NOTES:   
  If you want to turn off the breathing light at night, open 
Settings and touch Notification & status bar > Breathing 
light > Don’t light up at night and set the time period. 
  The breathing light will be turned off when Power-saver mode 
or Ultra Power-saver mode is on.
