On Android 7.1, whoever thought enabling Do Not Disturb mode during calls should be fired. Half the time coming out of DND alone, breaks my notification sounds.
1. Breaks notification sounds after DND is disabled/ends.
2. Phone calls should not have DND enabled by default. I have an automatic rule set and ending a phone call disables my DND rule.
3. After ending Bluetooth calls, DND will remain enabled (when it wasn't prior).
Don't force a mode on the end-user if you haven't ironed out all the kinks. DND should not mute notification sounds after it's disabled. A phone call should not disable DND if you had DND enabled prior.
I can use another app like Trigger to silence my phone instead of DND rules, but I can't disable DND during calls. This is counterproductive, Google!
