The problem is when I set an alarm clock, alarm will sound as ever, but then the tone or sound is not loud enough. I understand that the alarm is in an ascending order that is soft and a loud voice, but I still feel that it is not strong enough yet. I tried to adjust the volume of alarm clocks, but fail to do so. Does anyone here know what I'm supposed to do? (Actually, the same also applies to my message of warning is not strong enough, however, how I can make it stronger?). I heard somewhere that repetition can be adjusted, I'm right? But why does my phone break-out time does not allow me to adjust? It just stays there for 10 minutes.
