I'm sick of this bug!! I've tried restoring everything with/without backup.. Rebooting my device like a million times.. I thought wiping all my data and starting like a new device would fix it, as read on some forums, but NO!! DO NOT wipe your data it won't do anything.. This an iPhone 6 with iOS 9.2.1 latest update.. I'm really hating Apple right now.. Do something Apple!! Can't play any games that need Game Center.. and my device can't stop freezing..
