Why does the Xiaomi 15 Ultra experience slight stuttering when sliding the screen?

Thank you for your support. Each phone undergoes strict professional inspections before leaving the factory, so you can use it with confidence. Stuttering is linked to the refresh rate of your display. If your phone is set to a lower refresh rate, the smoothness of screen transitions, like scrolling or swiping, not be as fluid. This can cause a slight delay or jerky motion as you slide through the interface. For a smoother sliding experience, you can manually set the refresh rate to 120Hz, which should help improve the experience.
If you notice stuttering while multiple apps are running in the background, try closing unnecessary apps to free up system resources. Accumulated cache files in apps can slow down performance. Clearing the cache helps alleviate minor lag or stuttering issues.
