Since about a month ago, my DND shuts off before the end of the scheduled time. I have multiple schedules and, it doesn't matter which one I use, it shuts off. I'm not sure exactly when it shuts off, but sometime between 1am and 7am. I know because I am woken up by the phone vibrating. I will then but on DND again by # of hours from that point, and it seems to stay on until end time.
For example, The DND notice will state "DND is scheduled to stay on until 9am", but then it will shut off prior to that.
Things I have done:
Deleted all schedules and redid
Cleared cache from phone in startup menu
Tried to create a "sleep mode" and use DND feature within the mode instead
I usually set it to "Until I Turn It Off". You *might* be able to set a routine to automatically put it in and then take it out of DND Mode. Otherwise I'd do it manually as long as you remember to turn it off each time.
