If you would like to turn on Night Shift temporarily, tap the toggle switch next to ‘Manually Enable Until Tomorrow’. Night Shift will remain active until sunrise (or your set end time) the following day unless you manually turn the toggle switch back off.
Adjust the slider labelled ‘Colour Temperature’ to alter the amount of blue light emitted by the screen. Adjusting the slider to the left reduces blue light, making the screen appear redder and less bright. Adjusting the slider to the right increases blue light, making the screen appear bluer and brighter.
