I Can't log to my Game Center' account. I write my Apple ID and my password but it says that my Apple ID or my password are wrong but I know that they are right because they work in the App Store and iClou, what sh I do??
iPhone 6s Plus, iOS 9.2.1
Reset the device:
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
If that doesn't help, tap Settings > General > Reset > Reset All Settings
If that doesn't help, tap Settings > General > Reset > Reset Network Settings
You will have to re enter your Wi-Fi password.
No data is lost due to a reset.
