The Xiaomi 14 display appears reddish at low brightness when the screen temperature is high

Thank you for your support of Xiaomi. The phone goes through strict professional inspection before leaving the factory. You can use it with confidence.
The phone adopts the innovative LTPO technology, which allows for adaptive refresh rates under various brightness and scene conditions. It utilizes PWM dimming to ensure display effectiveness at low brightness levels. You will notice slight variations in brightness during transitions between high and low brightness. This is a normal phenomenon.
