Why does the screen of the POCO X7 appear red or green when viewed at an angle?

When titled to look at the phone, due to the different refraction of different colors of light, there will be a slight color difference, which is a normal phenomenon.

For your reference, here is the method:
1. Go to [Settings] APP on the phone;
2. Select [Display & brightness];
3. Tap [Color scheme], and adjust the position of the dots on the color temperature dial, and change the preference for screen display effects.
