I've noticed same issue on BQ E5 on OTA-12 and OTA-13. Sometimes incomming call gets silent after a split second (I can hear a blip of sound).
Attaching syslog and unity8.log of that exact minute it happened. There are no lines in media-hub log. ** Attachment added: "syslog" https://bugs.launchpad.net/ubuntu/+source/media-hub/+bug/1612367/+attachment/4748323/+files/syslog -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1612367 Title: [Touch] Incoming call gets silent randomly To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1612367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
