Why does the POCO C85 sometimes flash white when expanding grouped notifications on the lock screen?

We appreciate your support for Xiaomi products. On the POCO C85, the lock screen sometimes flashes white when expanding grouped notifications. On the POCO C85, this occurs when a new notification arrives before being grouped with an existing notification. These notifications appear briefly below the grouped notifications before being merged.
If your POCO C85 screen goes white when you expand grouped notifications on the lock screen, please refer to the following details:
  1. This does not affect normal use and is not a cause for concern. Animation effects will be optimized in a future major HyperOS 3 update.
  2. Avoid excessive background tasks that can cause excessive system load and maintain smooth system operation.
  3. Clear cached data on the system home screen or notification-related apps to prevent white flashes caused by abnormal cached data.
  4. Restart the phone and try expanding grouped notifications again.
