Ok this does not happen after you have first flashed/upgraded the phone (as I do every evening) but by the morning when I'm on the bus it has happened, I'll list what I usually do and my suspicions.
1) Upgrade device 2) Device starts charging 3) Toggle silent mode 4) Plug and unplug headphones 5) Set an alarm 6) Alarm sounds, which is then dismissed 7) Device stops charging 8) WiFi Access point is lost and mobile data is used 9) SMSs are sent/received. I currently suspect it is something todo with the alarm sounding and being dismissed, as I have only starting seeing this issue since I've been using my device for an alarm. However I will try and isolate the issue so there are reproducible steps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1458897 Title: [mako] When starting/seeking music the volume notification appears To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-sound/+bug/1458897/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
