I recently upgraded my phone to Galaxy S5. This phone has 4.4.2. One big inconvenience I have encountered so far is the way the event and notification work - the system automatically dismisses a notification when I tap on the notification to check the detail. Usually, I can only prioritize what I am doing and the upcoming events after seeing the event detail. But by tapping on the notification, the notification is dismissed and will not show up later, should I decide to ignore the notification for now.
Previously on 4.0, unless I mark a notification and tap on a dismiss button, the notification stays. I would like to keep the old behavior if possible.
