I am not sure if it's the same bug, but for me (E5, OTA-12), I do not get sound notification at all (sometimes I do though), even if device is unlocked.
I do hear vibrator, see green blinking light, but no sound. I am quite sure that Sound options are set OK. I've attached tailed syslog.log and unity8.log. ** Attachment added: "tail.log" https://bugs.launchpad.net/ubuntu/+source/indicator-messages/+bug/1516696/+attachment/4720668/+files/tail.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1516696 Title: SMS notifications are received only when the phone is unlocked To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1516696/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
