Contacts on iPhone are missing

Most often, owners of the iPhone 4S face this problem. Why have contacts disappeared on iPhone and what to do in this case? Is it possible to restore them? Do we need PC and iTunes, like when recovering a program deleted from iPhone. or are they not required? It is to these questions that our article is devoted.

Why contacts disappeared on iPhone?

In fact, there are many reasons why this could have happened. As you know, a copy of iPhone contacts is stored in the “cloud” storage iCloud. If we go to the settings and scroll the slider (opposite the “Contacts” item) to an inactive position, then we simply won’t see them.

It is recommended to immediately check in what position this very slider is. We add that for successful synchronization with the “cloud” you need Internet access.

If scrolling the slider to the active state did not help, go to iCloud and check if everything is turned on there. If there are no contacts, it is quite possible that we have not been online for a long time, and therefore the system was unable to synchronize. We connect to the network, then disable and enable the display of contacts in iCloud. We are waiting for a while.

If this also does not help, we try to import contacts from SIM. This is especially useful if we have just purchased our smartphone. Better to import all contacts at once.

If contacts disappeared in iPhone, you can try to restore them. Knowing how to use iTunes (for example, how to download music to iPhone in iTunes), why not try to restore contacts using this application? Of course, we will need to take care of the backup in advance, which would protect us from losing important information.

How to Recover Contacts on iPhone if They Disappeared?

The address book is constantly in sync with iCloud storage. Accordingly, you can restore a deleted contact from iCloud contacts, or even OS X. It is even possible to restore deleted contacts by re-synchronizing with the “cloud”. This method means that the phone numbers already existing on the mobile device will be synchronized with those stored in iCloud. Unfortunately, this method does not always work, but it is worth trying.

Next way: restore numbers from iTunes backup. This will work if you regularly synchronize your smartphone with a PC. In addition, the advantage of this method is that it guarantees recovery if a backup is available. We connect our device to the computer with which we synchronized it, launch iTunes on the PC and go to the restore from backup menu. We select the last backup, that is, backup, and begin the recovery process.

What about those paid apps from the App Store that also promise contact recovery? Most of these programs do not provide any guarantees at all, so it is better not to spend money on them.

we repeat that the best way to protect yourself from data loss is to create backups (in iTunes on PC, as well as in iCloud).

Contacts disappeared after flashing (software restore), factory reset or iPhone repair

If the subsequent entry of the Apple ID in the iCloud section does not download contacts, then it will be impossible to restore them.

Why did it happen. Contacts were entered manually without syncing with iCloud. If synchronization with iCloud is not performed, then after reflashing the iPhone through recovery or in the event of a device breakdown, all contacts will be irretrievably lost.

Delete contacts from iPhone one by one

On your mobile device go to the Contacts app.
2. Select the entry to be deleted.
3. In the upper right corner, tap on the Edit button.

In the tab that opens, at the bottom of it, click Delete contact.
5. Confirm the deletion.

Deleting all contacts from the iPhone is possible in the special case of synchronization with an empty Outlook or Windows Contacts library. We described this option a little earlier. To do this, simply connect your device to your computer and sync your contacts with an empty app. Also, all contacts are deleted when restoring iOS firmware. But in this case, you will lose all other personal data.

Greetings to all! When you have hundreds of entries in your phone book, the need for a convenient search for contacts increases several times. IPhone owners can solve a similar problem directly in the application of the same name or using Spotlight. And this is really convenient. you entered any data about the subscriber (or even a few letters) and here he is on the screen, you can immediately call or write an SMS. But this is not always the case. Often, especially after iOS updates, this very search simply does not look for contacts, although of course they are in the phone and have not disappeared anywhere.

The same misfortune happened to me, at one “fine” moment the iPhone simply stopped showing phonebook entries, although nothing special happened to the device. But I managed to quickly fix this mess. How? I’ll tell you now!

First of all, about what Apple representatives say about this on the official support forum. And they offer us:

  • Update or reinstall software.
  • Erase all data.
  • Set up the machine as new (remember).
  • Make a hard reboot (second point in).

Not bad? Then it will become clear to anyone that after such operations everything will function as it should. Fortunately, you can use other, less radical methods to deal with the broken contact search on the iPhone.

And everything is so individual that any of the proposed methods can help. Here’s what we found on the Internet:

  • Just edit any of your contacts.
  • Disable phone book sync with. If, of course, it is included.
  • Change sorting in the directory. For example, you have set. “Name, surname”, do the opposite. To do this, go to Settings. Mail, addresses, calendars. Sorting.
  • (any, you can then delete) go to the phone book on the iPhone, in the upper left corner we see the group item, go to them and click “done”. Search should work.
  • For a short time (3-5 seconds) we turn off the synchronization of the phone book in iCloud, then turn on.
  • Turn off Siri suggestions for searches. You can do this in Settings. General. Spotlight. Relevant for iOS 9.

Perhaps these are all ways to get the phone directory search to work correctly on iPhone.

Yes, you can’t call them official and “beautiful”, but in any case it is better and faster than updating the iOS software several times or deleting all information, as Apple technical support operators advise us.

For many experienced smartphone users, the loss of contacts is the worst thing that can happen to a gadget.

Phones, birthdays and addresses of the right people have been collected for years and entrusted to the iPhone for storage so that nothing is lost, even backups are created. Despite this, gadgets manage to lose the necessary records.

This does not always happen and not with everyone, but the problem is clearly not an isolated one. Here is Nikolai’s story:

Importing contacts using iTunes

Launch iTunes.
2. Connect your mobile device to your computer.
3. Select your iPhone in the list of connected devices and go to the Details tab.
4. Activate the item Synchronize contacts with.

6. At the bottom of the page, go to the Additional section.
7. Open Replace the following information on this iPhone and check the box next to Contacts.
8. Click Sync.

What to do if contacts are missing on iPhone

This strange iOS bug was discovered a couple of weeks ago, and a guide to fix it was not long in coming. To bring the Contacts tab back between Recents and Keys, first go to iPhone settings, select iCloud, and check if the toggle switch is turned on for Contacts. If it is active, disable it and enable it again.

After that, perform a forced restart of the device. hold the Home button and the power button until you see the Apple logo on the screen. As soon as the system boots, open the “Phone” application. contacts should be in place again.

In 99% of cases, this method should help.
