Why do the icons of the Xiaomi MIX Flip turn big or small when switching inner or outer display?

The Xiaomi MIX Flip is designed to provide an optimized experience on its displays, involving different fonts or icon sizes to maximize usability and aesthetic appeal on each display. The Xiaomi MIX Flip comes with adaptive display settings that automatically adjust the elements of the homepage based on the screen. This ensures that icons and fonts are appropriately sized for the current display's characteristics. If you adjust the size in [Accessibility], the icons will have changes of the size when switching the display. Please set the defaulted size and adjust the size of font and icons in [Settings] >> [Wallpaper and personalization] >> [Fonts] or [Icons].
