Automatic Do Not Disturb for Calendar events on Samsung Does anyone know of any free apps that can control the Do Not Disturb based on Calendar events? I know this is built into Android OS10, but Samsung has removed that from their phones. I know of one app that should work but it does a lot of things I do not need and costs money for what was originally built in but removed by a second party.
You can try IFTTT, Automate, Macrodroid app and automate that.

look given examples and try to create automation script for those calendar events.
