Turn Auto Brightness On or Off auf Realme
Auto brightness on Realme phones uses the ambient light sensor to raise or lower screen brightness based on your surroundings. When you drag the brightness slider manually, the system often disables this automatic adjustment, leaving the screen locked at one level regardless of lighting changes.
This becomes noticeable outdoors, where a fixed brightness feels too dim in sunlight, or at night, where a fixed high brightness strains your eyes. Re-enabling auto brightness restores the sensor-based adjustment without needing manual changes throughout the day.
Where to find the setting
Go to Tap on Settings ➔ Tap on Display & brightness ➔ Enable or disable Auto brightness. Toggle the switch to activate automatic adjustment, or turn it off if you prefer fixed manual control.
Disabling auto brightness makes sense for color-accurate work, gaming sessions, or reading under stable lighting where you want one consistent level. For everyday use, keeping it enabled usually helps battery life, since the sensor avoids unnecessarily high brightness in dim rooms.
