Did anyone share with my similar circumstance? I am used to use my mobile as an alarm clock for morning calls. It worked fine on my all previous Nokia's simple phones. However, I face a problem when I switch into Milestone this month. I have 2 cases that the alarm clock (default in Milestone) failed to alarm. Both cases, I need to restart the OS until it resumes to normal. 1st of the cases - the alarm seemed to alarm before with no sound, noting that the music player's unable to play sound as well (audio device unconnected?). 2nd of the cases - happened this morning. No alarm again and I found a message for force close dialog on OS.Process. It give auto reboot showing Android startup logo on screen... I find it's insecure of using my mobile as my alarm clock. It is very obvious if I compare it with Nokia simple phones. I don't reboot my phone until it stuck. And I like use Taskiller to kill some used apps. For example, killing music apps before listening albums. Does Android phone require daily reboot so that it work properly on going? And the Taskiller may be the cause of abnormality? Anyone shed me some lights?
