I got a similar behaviour on verla with my Xperia 10 II. I got notified by KDE Connect, but my phone wasn’t ringing even it’s not in silent mode.
Screen wake up without the correct behaviour and there was an icon representing a call at the bottom of the lock screen. Unfortunately, I don’t remember exactly how it was.
I tried to find who called me, but nothing has been saved. No history, no logs. I only can provide infos from journalctl.
I decided to enable Phone app log as is it described on wiki.
Should I copy what I retrieved from my logs? Or wait that this bug reproduces the next time? Is there a way to retrieve log from oFono without running the Ofono Log and at specific time?
Thanks
