Remove notifications "Activate Anti-malware service" and "Battery fully charged" on rooted Samsung S10 On my Samsung S10e device I often get these notifications:


  Device care - Activate Anti-malware service


and


  Battery fully charged


When I try to turn one of them off, I am told:


  These notifications can't be turned off


Which raises the question: On my rooted device, how can I turn them off?

Solutions that only work for one of these notifications are OK.
If you want to "flex your root muscle" so to speak, there are options using Xposed modules, but these options do not require it.

Battery full notifications are a bit of a workaround:


Open Settings and select the Notifications option
Click See All under the Recently Sent list
Select All from the dropdown in the top left
Click the 3 dots in the top right and click Show system apps
Select System UI
Click the Battery full item
Edit the options as desired


As for Device care, that is a little less of a workaround:


Open Settings and select the Device care option
Click the 3 dots in the upper right of this screen
Select Advanced 
Slide the Notifications switch to off


This option may have been part of the Android 10 update. If you do not have this option:


Open Settings and select the Notifications option
Click See All under the Recently Sent list
Select All from the dropdown in the top left
Click the 3 dots in the top right and click Show system apps
Select Settings
Click the Device care (Important) item
Edit the options as desired
Return to the previous list
Click the Device care item
Edit the options as desired


Keep in mind that this will disable all Device care notifications. If you went with the second method, you may want to try disabling one at a time to remove the notification you want without necessarily removing all of them.
