iOS 6 Notification Sounds w/out Notification
For the past few days I'd been experiencing a strange phenomenon on my iPhone 5 running iOS 6. Every so often the notification sound would play, but there would be no notification displayed. The timing was seemingly random and could happen at any time of the day, no matter what I might be running (or not running) on my iPhone at the time.
I figured it might be related to disabling notifications as I recently turned some off for a few apps. Turns out that's what it was. I had disabled notifications in the Notification Center from the Slickdeals app, but that app was still sending out notifications. When I turned notifications back on for the Slickdeals app in the Notification Center, a whole list of them was displayed in the iOS pull-down menu. Notifications that were previously hidden but still occurring. These notifications were being issued even with the Slickdeals supposedly app force-quit.
To fix this, I had to change my notification settings within the Slickdeals app itself.
