Switch off auto-brightness
iOS devices use an ambient light sensor to adjust brightness levels based on the light conditions around you. The sensor lowers brightness in dark locations and raises brightness in light locations.
You can turn auto-brightness on or off as follows:
1. Go to Settings > Accessibility > Display & Text Size.
To reset the auto-brightness settings, turn off auto-brightness and then turn it back on.
