Alarm doesn't work properly
The whole point of setting the alarm is that you can just leave it and know that it will go off at the assigned day and time. Unfortunately, it is just not reliable at the moment. I have already been late for work once, and have gone back to using my WinMo phone for the alarm, as at least that works every time.
It does seem to be an Android issue, I have seen it mentioned on other forums for other handsets, but I want to track down exactly what might be causing it on the Hero, and if there is a work around until HTC/Android releases fix it.
First off, the screen is switched off, but the phone is stil powered on, just like any other phone when you have the alarm set.
When I got the phone on Thursday, I set the alarm for Monday through to Friday, 10.30am.
Friday morning, the phone wakes and the alarm goes off at 10.30. Fine.
Monday morning, nothing happens. Go into the settings, check alarm set for the correct time and day, all is fine, it just didnt go off.
Tuesday morning, it works fine, phone wakes and alarm goes off at 10.30.
Wednesday morning, nothing. WinMo phone alarm wakes me at 10.34. I switch on the Hero's screen, and immediately the alarm goes off, 4 minutes late!
Last night I didnt charge it, thinking it may be an issue when being charged. But this morning it didnt work, so it is not an charging issue.
The Alarm icon was showing the top corner, so the alarm was obviously set, and the Clock App was still running (I checked in Advanced Task Killer). I will try to set it again tonight from scratch, and see if that works.
Having to set it every night would be a pain, but at least it would actually work like it is supposed to.
