Inactive Click for Apple ID
Hi,
I'm having a problem on iPhone ONLY. The apple id option on Settings-->iCloud or Settings--> iTunes is INACTIVE. I can't click on it, this way I can't access anything that requires my apple id. It has a Grey Color instead of blue (see images below)...I can use my id on ANY device but the iPhone. I tried hard reseting, I tried logging out from every device through iTunes on my Macbook but nothing changed actually, the icons for App Store and iTunes disappeared. Can someone help me please?
iPhone 6, iOS 8.4
