Two days ago, I set an alarm on my iPhone and laid down to take a nap. But It didn't go off, no sounds at all. I ended up missing an important appointment. After that, I came home and check the alarm clock. The alarm screen still showed up but there is no sound. I did check the volume, restart the device but nothing worked. Couldn't figure it out. Has anyone else here had the same issue with alarm app as mine? Is it due to firmware problems?
