This happened to me a few times indeed, unfortunately I've no idea how to reproduce that or what's causing it.
One thing for sure is that unity8 isn't. It also seems to be hardware- specific, no other device has done that. When this happens to you again, will you please post the contents of /var/log/syslog and the output from: $ adb shell /system/bin/logcat Maybe it will shed some light... ** Also affects: canonical-devices-system-image Importance: Undecided Status: New ** Also affects: turbo Importance: Undecided Status: New ** No longer affects: unity8 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1611374 Title: Phone vibrates randomly, turns on flash To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1611374/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
