What is the 'Daydream' feature found on the LG G2 handset?
Day Dream runs following Auto Screen Time-out settings when the phone is connected to a rack or charger.
For the screen to be displayed in stand-by mode, 4 effects (clock, photo table, photo frame and color) are selectively available.
Day Dream runs in one of three modes: “Connecting to rack, Charging or Connecting to rack or charging”.
Settings → Screen → Day Dream→ Select a preferred screen.
