Question:  

After OS upgrading to Android 11, charging information is not continuously displayed on bottom of the screen when connecting (wireless) charger. What should I for this?

Answer:

After updating to Android 11 (R), the way charging information appears on the Always On Display (AOD) screen has changed. Previously, the charging details were constantly shown at the bottom of the AOD screen while charging. However, now the charging information appears for a brief period of 5 to 10 seconds after connecting the charger and then vanishes. To see the charging information again, simply tap on the AOD screen, and it will display for another 5 to 10 seconds.S, displayed charging information
