I use the alarm clock feature daily, well - I used to. It no longer works for me. If I set an alarm for 5 minutes from now, it'll work perfectly. If I set the alarm for 6:00am tomorrow, it will not go off. I have volume up and all obvious settings correct, but this no longer operates for me. It's been about a week. Are there any possible updates I can install? I can remove and re-install this clock application?
