6.4. Adjust the screen brightness and
color temperature
Adjusting the brightness on your realme phone tailors visibility to suit your
environment. You can manually dim the screen when reading in bed, for
example, or make it brighter when you're in a direct sunlight situation. Or use
Auto-Brightness, which can automatically change screen brightness depending
on the level of ambient light. Reducing screen brightness can also help to
conserve battery life.
