This question already has an answer here:
Scheduled turning the device off and on has apparently been discontinued in Android 8. Edit: At least for my device thats the case.
Given that it was one of my favorite functionalities in android 7, I would like to retain it through the update to 8.1.
Is there a similar function on 8.1 or an app i can use to emulate it?
Taskr and Automateit require root access to be able to shut down the device.
