Those who have updated their devices to Apple's latest iOS 7.1.2, which was released in the beginning of this month for compatible iPhone, iPad and iPod touch models, have come across an issue of contacts disappearing from the Contact app.
The issue is the iPhone or iPad defaults the "On My iPhone" contacts group after the device is updated to iOS 7.1.2. The issue is not related to the iCloud sync. Thankfully, there is a workaround available for this. In order to get the disappearing contacts, users will have to only change the default in Settings back to iCloud.
Below are two easy methods: One showing how to change the default back to iCloud and the other one is to get the disappearing contacts.
Those who are facing the same, may try the following trick to get the disappearing contact again.
How to Default Back to Save Contacts to iCloud
Step-1: Go to Settings app on the iOS 7.1.2 running device
Step-2: Scroll down and tap on Mail, Contacts, Calendar
Step-3: Under Contacts, tap on Default Account
Note: Ensure that iCloud is selected, but not On my iPhone
There is no way to toggle where contacts are saved after adding them. In order to get the missing contacts into iCould, copy the numbers and create new entries once you have defaulted back to iCloud syncing. Below is the procedure to find missing contacts.
How to Find Out Disappearing Contacts
Step-1: Open the Phone app on your iOS device
Step-2: Tap on Groups at the top left
Step-3: Uncheck All iCloud and check All on My iPhone
Step-4: Tap Done at the top
Step-5: You should now see a list of all the contacts which were missing from the list
For some users, the problem group will be "All on My iPhone." When you have the list of friends who needs to be added back, ensure that iCloud is selected under groups. One of the easiest ways is to hide the "On My iPhone" group.
