The screen was locked and I pressed the power button to unlock the screen. The phone did not react on any pushed buttons. The phone continued ringing but I was not able to do anything with the phone during this time. During the next minute the phone was blocked. After this period a "restart" followed. "Restart": The restart was not a real reset. The phone screen was black. Then approx. 1 - 2 minutes after the call was gone, the screen went on again and the ubuntu logo with the dots appeared (same screen when you start the phone but without the "bq"-screen). I did not need to enter the PIN code of the SIM card. The phone was again fully operational. This happened on January, 10th at approx. 13:30 h. I have attached the sys.log for your review and hopefully for tracing back the issue to the root cause.
