HOW TO REPRODUCE: 1) Move to a place where many wifi hotspots are available 2) Connect the device via USB and run "phablet-shell" and then "dbus-monitor" 3) Use the device while keeping an eye on dbus-monitor output To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1480877/+subscriptions -- Mailing list: https://launchpad.net/~ubuntu-sdk-bugs Post to : ubuntu-sdk-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-sdk-bugs More help : https://help.launchpad.net/ListHelp
