Had this occasionally with every android phone I've ever had. Nothing to worry about unless it starts doing it very regularly and even then a factory reset should sort it. Unlikely to be a hardware issue.
One or more apps have likely crashed in the background and caused a Kernel Panic, causing the phone to reboot...a bit like a Blue Screen of Death on a PC.
Thanks for responding. It happens like 2 times a week. Is it normal? I don't have such a problem on my HTC U11 if I recall correctly.
My phone still reboot itself once or twice a day after motherboard replacement. Previously can be multiple times like 5 or 6 times.
However, no issues when using Google 2 pixel.
Happens to me too, about twice a week. Very unlikely to be a hardware issue, since I've had it happen on two different P20 Pro phones. Factory reset does not work.
So now I'm removing one app at a time... Fitbit was not the culprit. NEXT!

If someone with this issue wants to compare apps privately, I'm up for that. My e-mail is my username here + gmail.
I've had this issue also. A couple of times a week it restarts.
It's annoying that there's no fix
Can anyone tell me where I can see a log on the phone that shows these issues please?
