I can't access my control Center while I'm using an app
When I'm on my home or lock screen I can swipe up and change the current song or use my calculator, but when I'm in any app, let's say google chrome, I can swipe up and nothing happens so I'll hit the home button and swipe up again and then the control Center comes up. What's wrong here? What can I do? I have a gold Iphone 6. This has been like this since i can remember. I got the phone in August of 2015
iPhone 6, iOS 9.1
