I use my cell phone as my alarm clock, and it works most of the time. The problem is, sometimes the alarm does not go off for seemingly no reason. It has done this three times so far. After the second time, I even set five alarms at one-minute intervals to each other for backup. This morning, none of them went off. One even set itself to 6 PM instead of AM.
I have checked this forum for answers, and the one answer that I seem to have consistently gotten is to check if the tone is "Light Only," and I did, it's always been set to Tone.
How can I prevent this from happening, and how do I test it to see if it works? I have missed my first class three times because of this.
