Do not disturb does not work

[iacobau]

When I switch Do not disturb mode ON it has no any effect. Calls and notifications sounds are still the same as before. I tried safe mode as well, still the same.

I use xperia assist actions and it is able to switch phone into silent mode when action is active. But by switching on Don't disturb at any time when no action is active it has no effect. I have this phone only 5 days so it do not need full reset.

Go to Settings -> Sound -> Do Not Disturb and revise the settings on that page. Maybe something is messed up about "Behaviour" or "Exceptions" tabs.

I checked it many times and I tried several combinations of these settings. Still the same. My phone's build number is 52.0.A.3.202
