My A6 Plus was OTA updated yesterday, now it have
DND worked perfectly before the update, now the phone vibrate on all notifications all night long. It is set to allow only calls from starred contacts and no messages. I always leave sound on with "vibrate on call" turned off.
DND is scheduled every day from 21:00-7:00. Between this period, if any(!) application have new notification, the phone vibrate. On incoming calls from not starred nubers, it stay silent with no vibration.
I don't want to turn off notifications for all applications one by one, becouse I need them when DND is disabled. DND was perfect, but something went wrong during the last update.
