After the release of Android Jelly Bean 4.3, may be you have heard about a new feature: Notification history, which would be a screen showing not only the current notifications but also past ones. If you have not heard than it is also a not a big thing because they didn’t make any mention of it in their What’s New page. Although now What’s New page is all about Android 4.0 KitKat at this date.
You can follow the steps described below to use this function of Android 4.3 .
1. Go to your App drawer in Widgets tabs and drag and drop the Settings icon to the home screen.
2. A new window will pop up asking what function do you want to have as a shortcut, select the Notification option.
3. Go back to your HomeScreen and select the setting icon. There you will see all your Notification history.
Remember: if you turn off notifications for any app, you will not be able to see your notification in this Notification History, you may miss important alerts and updates.
