Why is the screen brightness low when auto brightness is enabled on the REDMI A5 indoors at night?

Thank you for supporting REDMI products.
If the brightness is low when auto brightness is enabled indoors at night, please refer to the following details:
1. The virtual ambient light sensing system operates differently from traditional physical light sensors, as it relies on software algorithms rather than dedicated hardware to detect changes in environmental lighting;
2. As a result, its accuracy can be limited, especially in dim or dark environments, where there will be a slight brightness difference with the actual brightness level required for comfortable viewing. This can lead to the screen appearing dimmer than expected;
3. To ensure optimal screen visibility in such situations, it is recommended that you manually adjust the screen brightness through the settings whenever necessary for a better viewing experience.
