The Xiaomi 14 Ultra features a 3D flexible display screen, where slight color differences appear in the curvature area of the phone due to the varying refraction of light across different colors. This is a normal phenomenon. Xiaomi rigorously tests its products before they leave the factory to ensure they meet our specifications, making you feel free to use them. Additionally, you can adjust the screen color by navigating to [Settings] >> [Display & brightness] >> [Color scheme]. From there, you can fine-tune the color temperature by adjusting the position of the pick-up point on the dial according to your preference.
