I did a test right now, and I managed to reproduce it at the first attempt. I just asked my wife to call me, and I didn't pick up the phone or touch it. Initially, the pickup dialog appeared, but after some time, while the phone was still ringing, it disappeared all by itself.

The device was ringing but in dark without presenting the slider to pick-up the call or to reject it. When she came home I could proof this and have had to reboot the BQ. I have some log files because I was monitoring every 300 secs all running processes (ro catch some other battery drain issue) and will attach this log later.
