I haven't experience this problem... but I must admit I misunderstood your topic...

I'd like to have a way to disable notification sounds while I sleep!!

-SF

 

What are your settings?

 

I'm a pretty deep-sleeper but my Moment chimes whenever an email comes in-even when it is sound asleep.
You CAN set the alarm to ring audibly in spite of having everything else silenced. It is in the alarm settings.

 

lol

 

Ok, my little LG Optimus Zone 2 does the same thing, when its asleep, which is when ever its not in my hand and on, K9 does not alert me when I get a email, or the stock message app I believe, unless I pick it up and wake it, and it connects to the wifi. Im always around a wifi so I usally have data turned off to save money. Ive checked all the settings, its suppose to check for email and messages every 5 min, so.....WTF?
