Here’s a suggestion from iMore’s Ally Kazmucha for users that are experiencing vanishing or incorrectly syncing iCloud get in touches with once they’ve upgraded to iOS 7.1.2.
It turns out the issue isn’t with iCloud, it’s with a new default in iOS 7.1.2. The update reasons your iOS device to change your contacts back to the On My iPhone group. To take care of the problem, merely switch your get in touches with group back to iCloud in setups.
1. Go to the Setups application.
2. Visit Mail, Contacts, Calendars, and scroll to the base.
3. Select Contacts.
4. Click on Default Account.
5. Finally, choose “iCloud” rather than “On my iPhone.”
Kazmucha has actually additionally written up a tutorial on ways to remove disappearing contacts from your phone. To review that head over to iMore.
