How to return the notification bar after Android update
There was a problem that after updating Android to version 11, the notification bar stopped working [ phone model - Realme 6 pro, but it may work for others as well].
How did we fix it:
First you need to check that this item is active in your phone settings:
Settings - Notifications and status bar - “Pull down on the lock screen to open the notification panel”
Then we blocked the phone. In the locked mode we tried to pull out the notification bar.
After the notification bar is activated in the locked mode, it starts to work in the main mode as well.
