Could you expand on what you did?  Currently, I'm having app problems with paid apps, and other pesky problems like the disappearance of the notification LED for alerts and push notifications just to start.  I do not want to play an annoying "sound file" or have my phone "vibrate" when I get either a notification from an app.  Even text messages do not use the LED for notification anymore.  All I want to do is glance at my phone, and if the blue LED is flashing, I know to look further.

Android is turning into Windowz... with each "update" of their software they seem to introduce dozens of "bugs" to complement it. ; )
