Why is the screen of the Xiaomi 15 yellowish or dark when using Mi Mover or after using it for a period of time?

Thank you for your support. The Xiaomi 15 undergoes a thorough inspection and color calibration before leaving the factory, ensuring that the screen is of high quality. However, if you notice that the screen appears yellowish or darker after using Mi Mover, transferring data, or after extended use of high-load APPs, this is due to the device's built-in high-temperature protection mechanism. When the phone detects an increase in temperature, it automatically adjusts the screen brightness to prevent overheating, which can cause temporary changes in the display's appearance. Once the phone cools down and the temperature returns to normal, the screen display will automatically return to its original state. This feature is designed to protect the device and enhance its service life, so you can continue using it with confidence.
