Thank you for your support of Xiaomi products. The screen of the mobile phone has undergone strict professional testing before leaving the factory, so you can use it with confidence.
In a dark environment, the screen color difference is caused by the camera imaging principle, not the problem of the mobile phone screen itself. Usually, in a dark environment, in order to fully expose the photo, the camera will increase the exposure to make the picture look brighter in the dark. This operation will also make the originally unnoticeable details and colors more prominent, which is different from the effect of direct observation with our eyes. These are all normal phenomena, please feel free to use
