We are accustomed to the fact that in iOS there are no tweaks and system parameters. Even the image on the screen is not adjusted and not calibrated by the user.
Not everyone knows that the system has a special section that allows you to adjust the screen settings for themselves.
How to change display settings
1. Go to the Settings – Basic – Universal Access – Display Adaptation – Light Filters section .
2. Activate the Light Filter switches and select the Hue mode .
3. Use the Intensity and Hue sliders to select the appropriate mode of operation.
So it will turn out to adjust the temperature of the display to warmer or colder without using the option Night Sift .
