Note 8 decided to reboot itself

I had to reboot the phone when some apps like Gmail, Paypal started freezing. all fine now. I've got the Qualcomm version in the US.

Everything fine after the reboot.
 
I would do a clear cache once a week if streaming a lot but performance mode should look after it too

Thank you. I have done the cache clearing a couple times I will possibly look into performance mode though I don't like the screen to be too bright

You can still manually reduce brightness anyway, I honestly don't see any power zapping from full performance mode compared to next level down, it simply manages your phone differently and quite possible better
 
Maybe some bug/conflict with an app you have. Maybe with the Security Update rolled out yesterday that it will resolve your issue.
