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 Touch seeded packages, which is subscribed to indicator-sound in Ubuntu. https://bugs.launchpad.net/bugs/1458897 Title: [mako] When starting/seeking music the volume notification appears Status in indicator-sound package in Ubuntu: Incomplete Bug description: What happened: 1) Open the music-app 2) Start playing a track or seek the playing track 3) Observe that the volume notification appears What was expected to happen: 1) At step 3 the volume notification should not be shown $ system-image-cli -i current build number: 194 device name: mako channel: ubuntu-touch/devel-proposed-customized-here alias: ubuntu-touch/vivid-proposed-customized-here last update: 2015-05-14 21:20:36 version version: 194 version ubuntu: 20150514 version device: 20150210 version custom: mako-1.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/indicator-sound/+bug/1458897/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
