Alarm won't go off and phone automatically switches off

[Galaxy J7 Pro]

My Samsung J7 Pro alarm does not go off in the the morning, I go to sleep with my phone on the charger while it's on but in the mornings my phone requests a pattern as if it auto restarted however my auto restart is off, hy does this happen?

Hey @Galaxy J7 Pro! Do you have any Bixby Routines active? They could be routinely restarting the phone. To check this, please swipe down to access the Quick menu > Bixby Routines > Details > My routines.
