The screen display of the mobile phone is sometimes yellow and sometimes white

After enabling the adaptive colors feature, the screen's color temperature will adjust according to the ambient color temperature, resulting in a more natural and gentle display of colors. Consequently, the screen display is sometimes yellow and sometimes white. This phenomenon is normal.
It is recommended to confirm whether the adaptive colors feature is enabled by going to [Settings] >> [Display & brightness] >> [Color scheme] >> [Adaptive colors] >> you can choose to turn it off.
