I recently read a question on Apple Communities, it said as below:
“I was updating my iPhone 6 to iOS 9.3.5, last night and this morning when i looked at my phone several of my contacts were missing. I tried to put a dare range to it but it doesn’t make sense. Some contacts that I have were added only months ago, while I am missing some that I have had for years.”
You may also meet this issue. Because, in the process of updating to a new iOS operating system, no matter recently iOS 9.3.5 or upcoming iOS 10, your device will be backed up and then restored. In the whole process, you should keep your iPhone connected to computer or iCloud in a stable state, or you may lose something. In this post, we give you some tips about how to restore iPhone contacts. If your iPhone contacts disappeared after iOS update, these tips may be helpful.
How to Get Back Missing Contacts on iPhone
- Restart your device, or Force restart your device.
- If you are using iCloud, you can go to iCloud.com to check whether your lost contacts are there. Or you can try to turn off iCloud and then login.
- If you are using Google contacts or some other email contacts, you can login your email contacts to get back lost contacts. Or re-login your email on your iOS device to retrieve disappeared contacts.
- If you have created an iOS backup, you can restore your device with the latest backup to get your lost contacts. Of course, sometimes when you don’t know whether the backup contains contacts, you can use backup viewers to check whether the contacts are backed up to the backup.
