Why do the Control Center and lock screen overlap on the POCO C85?

Thank you for your support of Xiaomi products. The Control Center and lock screen overlap on the POCO C85 when pulling down the Control Center after tapping Emergency Call on the PIN code screen.
If the Control Center and lock screen overlap on the POCO C85 when pulling down the Control Center after tapping Emergency Call on the PIN code screen, please refer to the following details:
  1. Check for system updates. This issue has been fixed in newer versions, so please update to the latest version.
