Although Jelly Bean brought some good features, it also caused some problems. Here are three work-arounds I found: Dimmer notification light. The notification is not as bright as it was, making it at times difficult to see. This was mentioned my a number of people, and confirmed by Verison. The fix is the Light Flow app; it doesn't have a brightness control, but seems to restore the brightness to pre-JB levels. Notification sounds are lower. My calendar notification sounds are lower with JB, even set to maximum volume. The SpeakerBooster app has helped. Blocking Mode and Verizon. Blocking Mode is an inherent part of JB, and passed onto the S3 by Samsung. For some reason, Verizon decided we didn't need it. In order to get it, use the QuickShortcutMaker app to put a shortcut on the home screen. Other providers have it in Settings (and at least one in the switches at the top of the pull-down shade), but at least Verizon subscribers can use it.
