Why does the notification bar prompt "Uninstalled apps leave residual items" after booting and entering the home screen on the Redmi Pad 2 4G?

Thank you for your support of Xiaomi products. The Redmi Pad 2 4G undergoes strict professional inspection before leaving the factory, and you can use it with confidence.
Please refer to the following explanation:
  1. After booting, the system automatically removes pre-installed APPs that are not required or supported in your current region. This helps optimize device performance and using experience;
  2. Because some files or data related to these uninstalled APPs can remain temporarily, the notification bar shows a prompt indicating that residual items exist. This is a normal system behavior during the cleanup process and does not affect device functionality.
