I have seen several people post online similar comments to this: "Why would you want to set an alarm in your alarm clock, but not have it work because you silenced your phone the night before so you COULD SLEEP? This makes absolutely NO sense. I would also like to be able to look down in a meeting and see if I have a text/email without having to unlock my phone."
Both of these things work as they should on my Note3 now. If I take a chance on the update to 5.0, should I expect the alarm to no longer work if the phone is on silent? What about seeing status bar notifications on the top of the screen when waking the phone with power button? I would not want to have to actually fully unlock the phone to see them.
