I'm using Alarm Clock Xtreme Free in the app drawer. Last week, I overslept and lost $75 for a training session because my alarm didn't go off. I checked and it didn't go off because it wasn't in the app drawer. This morning, I woke up a bit before my usual time and decided to check the alarm clock, just in case. Sure enough, it wasn't running and if I had slept I would have missed another $75 appointment. What's happening? The process is being killed somehow, even though it's in the app drawer and this shouldn't happen. How can I fix this? I'd rather not use MIUI's default alarm app because Alarm Clock Xtreme Free has many, many useful features.
