I've been having these issues ever since the IOS 8 update and no bug fixes has fixed them. I wanted to know of anyone else has experienced the same thing. Firstly, the control centre is often unresponsive. Swiping up will not do anything. Only after locking and unlocking the phone does the gesture work. Secondly and more annoyingly, when I get a whatsapp notification whilst I'm in an app the notification doesn't go away if I try swiping up. It gets stuck there and only goes alway if I rotate the screen or quit the app. There are a couple other issues but I'll lost those later. These two are the most prominent and annoying. Anyone had these problems?
