Why does the Redmi Note 13 Pro+ 5G screen turn red or green when viewed at an angle?

Thank you for your support of Xiaomi products. The Redmi Note 13 Pro+ 5G screen uses advanced OLED technology with the latest generation of emissive materials to enhance screen brightness. When viewing the phone at an angle, there can be slight color differences, such as the screen turning red or green. This occurs due to the refraction of different colored light, which is a normal phenomenon associated with OLED displays.
Xiaomi's products undergo rigorous inspection before leaving the factory to ensure they meet Xiaomi's high standards. You can use your Redmi Note 13 Pro+ 5G with confidence. We appreciate your understanding and hope you continue to enjoy using Xiaomi products.
