My phone alarm didn't work this morning, anyone know why?

Question

I set it for 6:30am last night, and I checked it after I saved it to make sure my tired brain did it right, and I checked it this morning when I woke up too...

And my phone didn't even say that I didn't hear the alarm (it does that if I don't press a button when the alarm goes off). =/ I ended up waking up at 6:47, so I wasn't late for school, but still.... grrr...

Anyone know what I can do to make sure it works tomorrow morning?

My phone is a UpStage from Sprint....

Answer 1

Give it a test. Set it for 3 minutes from now. Don't rely on just your phone alarm. Get a real alarm clock.

Answer 2
