Do not disturb schedule going from vibrate to mute with no reason

[Members_RZhHy3e]

Hey,

Since I got the recent update to One UI 3 the other week I've had an issue where my phone will be on vibrate, then a scheduled do not disturb will turn on overnight, and it'll turn off DND mode in mute the next day. 

Have tried to test multiple scenarios to resolve it, with no luck. Have tested in and out of safe mode on the same day, have tested with new scheduled DND's, done soft resets etc. 

It's obviously not the end of the world but is quite annoying to have to remember to put my phone back on vibrate every morning when DND turns off. 

Anyone got a fix?

the only thing I can suggest is Optimising all apps, preferably through the Galaxy Labs App Booster module. it is always a good idea to completely refresh the apps after an update. Couod be worth checking that DND permission for Phone & Sound is selected too, you can find this by opening Settings and searching for "Special Access". I will add that I have had a similar issue on my S21 Ultra, but with the Temporary Mute, it doesn't revert to Vibrate after the time is up, remaining on Mute. so it could be a U.I bug, but I am on 3.1.

Yeah I did that straight away when I got the upgrade, will do it again just in case. I think there is an issue with the U.I but I don't really know enough to test and prove it

Did you resolve this issue in the end? Mine is doing the same.

Thanks.
