Ok, so, I have noticed - and not just my tablet - but every android device I have ever had, the alarm has failed to go off in the morning, even though it's set. it will go off if you set it for a few minutes, maybe hours, but if you leave an alarm to go off by itself at an important time, it fails you. I wake up, and the notification is in my notification saying "Alarm set for xx:00 AM" and I tap it, and THEN it goes off, even saying that the alarm was set for the whatever the time was when I tapped the notification. USELESS. same thing on my phone, and my previous phone. Is this something with android or what? I need to sort this out or I am going to end up being late for something really important!
