Why does the screen of the POCO X6 Pro flicker slightly when lighting up?

Thank you for your support of Xiaomi products. The POCO X6 Pro has undergone strict professional inspection before leaving the factory, so you can use it with confidence. Under the combined influence of ambient light and screen brightness, slight differences in brightness during the refresh rate switching process can cause changes in visual effects when the brightness is low. It is recommended to moderately increase the screen brightness, which will improve the visual effect.
For your reference, here is the method to adjust the screen brightness:
Go to [Settings] >> [Display & brightness] >> you can adjust the screen brightness by dragging the level bar.
