Using Duo Light

iPhone Duo: choose a light on the outer screen while the phone is closed, then open the phone to turn the light on. Close it to turn the light off and get your normal brightness back.
Other iPhones: choose a light, then flip the switch. Switch it off to change the light or your settings.
Colour: tap a preset, or use the Colour slider to set your own, from warm candlelight to cool morning light.

Common questions

The light turned itself off. That's the auto-off timer, which saves battery if you fall asleep. Change it or turn it off under Settings → Turn off automatically.

My screen brightness changed. Duo Light raises the brightness while the light is on and puts it back when the light turns off or you leave the app.
