how can I permanently disable the Game Centre?
I am running iOS 9.5 on an iPhone 5s.
I have absolutely no wish to play games with other people, and I never shall. It is therefore very annoying when the Game Centre keeps launching itself whenever I open a game on my phone and I am fed up with constantly having to cancel it.
Can I disable the Game Centre permanently and if so how?
iPhone 5s, iOS 9.0.2
