My iphone xr is muting all alarms when bed time is switched on
usually i used to plug in my iphone xr for charging overnight and all alarms are getting muted early in the morning and there is no sound out from it. and also i can't hear any sound if play a music. The volume is set to max and it is in ringer mode only
then i had shutdown my iphone and restarted then later sound is back
Is there any problem with my iphone xr or its a bug of ios 12.3.1?
iPhone XR, iOS 12
