On the POCO C71, you can notice that the sliding effect of the notification shade appears less smooth or visually less refined compared to some other devices. This is due to the specific style design of the notification shade in the system, and it is a normal characteristic of the stock Android interface.
It is important to note that this visual effect does not impact the actual functionality, performance, or usability of the mobile phone. All core features, including notifications and quick settings access, work properly. You can continue to use the device with confidence. There is no need for concern, as it does not affect daily operations or system stability.
